[0029] In one embodiment, Figure 1 This is a flow chart of an object transmission method provided by an embodiment of the present invention. This embodiment is applicable to the case of uploading Outlook emails to a task management system with one click. The method can be executed by an object transmission device, which can be implemented in the form of hardware and / or software. The object transmission device can be configured in an electronic device, such as an Outlook client. Figure 1 As shown, the method includes:
[0030] S110 . In response to a received object drag operation, a target memory address of a target drag function is obtained from a preloaded target dynamic link library through a preconfigured address extraction function.
[0031] Among them, the object dragging operation can be understood as the action of a user dragging and moving an object through an input device such as a mouse, a touchpad or a touch screen. Generally speaking, the object dragging operation can be an action of selecting one or more objects, holding down the mouse button or touching the screen and moving the finger, and dragging the selected object from one position to another. The target dragging function refers to a pre-created function for performing the extraction of file information of the object to be transmitted and storing it in the local file path, and obtaining the file information of the object to be transmitted from the local file path. In the actual application process, the target dragging function may include a file extraction variable, a file access variable and a file operation object. Among them, the file extraction variable can be understood as a variable for performing the function of extracting the file information of the object to be transmitted, and the file extraction variable can point to the object to be transmitted; the file access variable can be understood as a variable for performing the function of accessing the local file path of the object to be transmitted, and the file access variable can point to the local file path or the file operation object; the file operation object can be understood as an entity of a specific object or class for processing file-related operations, and the file operation object can point to the local file path. In one embodiment, the file extraction variable can be a variable pointing to the object to be transmitted, for example, the file extraction variable can be pDropSource. The file access variable can be a variable that calls a file operation object, such as pDataObj. At the same time, a CFile object can be constructed as a file operation object, pointing to a local file path, to achieve the acquisition of file information of the object to be transferred during the object dragging process. Among them, the CFile object is an object that can be recognized by the task management system.
[0032] The address extraction function can be understood as a function for obtaining the address of a specified function. Exemplarily, the address extraction function may include the GetProcAddress function. The target dynamic link library can be understood as a pre-configured link library that stores the memory address of a specific function. The specific function may include a target drag function and an original drag function. After responding to an object drag operation, the target drag function can be dynamically determined in the target dynamic link library to determine the target memory address of the target drag function. In actual applications, the memory address in the target dynamic link library can be updated in response to an object drag operation. The target memory address is the memory address of the target drag function. In actual operation, the target memory address may be an address dynamically allocated by the operating system during program execution and stored in the target dynamic link library.
[0033] In an embodiment, when an object drag operation is received, a pre-created target drag function can be called from a pre-loaded target dynamic link library through a pre-configured address extraction function. Generally speaking, the object drag operation can include the entire process of dragging the object to be transferred from the Outlook client to the task management system; or, it can include the instant process of dragging the object to be transferred to the task management system. In an embodiment, obtaining the file information of the object to be transferred can also be performed by a file extraction variable in the target drag function.
[0034] S120: Calling a target drag function corresponding to the target memory address to automatically store the object to be transferred to a local file path.
[0035] Among them, the object to be transmitted can be understood as data or entity to be transmitted by a certain method or mechanism. Exemplarily, the object to be transmitted can include but is not limited to emails sent through an Outlook client. The number of objects to be transmitted can include one or more. The local file path can be understood as the path for storing files or folders in a computer storage system. The local file path can be a string used to identify the location of a file or folder. In general, the local file path can be characterized by a drive letter, a directory name, a file name, and a separator. For example, in a Windows system, a complete local file path can include a drive letter + separator + directory name + separator + file name. The specific format of the local file path can be set in advance according to user needs. In one embodiment, the local file path can be an absolute path or a relative path, which is not limited. In actual applications, the local file path and the object to be transmitted can be a one-to-one correspondence.
[0036] In an embodiment, after determining the target memory address, the target drag function corresponding to the target memory address can be called to automatically store the object to be transferred to the local file path. In the actual operation process, the pre-created target drag function can be called to obtain the file information of the object to be transferred, and then the file information of the object to be transferred can be automatically stored in the local file path.
[0037] S130 . Access the local file path corresponding to the object to be transferred through the target drag function, and obtain the file information of the object to be transferred from the local file path.
[0038] Among them, file information can be understood as data of various descriptions and attributes contained in the object to be transmitted. The file information may include all data information of the object to be transmitted; or, part of the information of the object to be transmitted may be filtered. In one embodiment, the file information of the object to be transmitted includes at least one of the following: object subject and object content. The object subject can be understood as a brief summary of the object content, which is used to enable users to quickly understand the object content and the key information in the object content. The object content can be understood as detailed information that the user needs to convey. In actual applications, when the object is to be sent to an email, the file information of the object to be transmitted may include at least the email subject and the email content.
[0039] In an embodiment, the target drag function can be called to access the local file path corresponding to the object to be transferred, and the file information such as the object subject and object content of the object to be transferred can be read in the local file path. In the actual operation process, when the file access variable directly points to the local file path, the file access variable of the target drag function can be called to access the pointed local file path; or, when the file access variable directly points to the file operation object, and the file operation object points to the local file path, the file access variable of the target drag function can be used to access the pointed file operation object and access the local file path. At this time, the file information of the object to be transferred in the local file path can be extracted.
[0040] S140. In response to the received object release operation, the file information corresponding to the object to be transferred is uploaded to the task management system; wherein the file operation object in the target drag function and the task management system follow the same web page development specification.
[0041] Among them, the object release operation can be understood as the action of stopping dragging and moving the object through an input device such as a mouse, touchpad or touch screen after dragging the object to be transferred to a specified position through an object drag operation. Generally speaking, the object release operation can be the action of releasing the mouse button or stopping touching the screen after dragging the object to be transferred to the task management system through an object drag operation. The task management system can be a system for file collaboration and file sharing, and the task management system can at least include an ITM management system. Web page development specifications can be understood as the guidelines and requirements that need to be followed when designing and developing web pages, and web page development specifications can be used to ensure the quality, maintainability and performance of web pages. In the actual operation process, the web page development specifications can at least include the Request For Comments (RFC) specification and the Hypertext Markup Language 5 (HTML5) specification.
[0042] In an embodiment, when an object release operation is received, the file information corresponding to the object to be transferred can be uploaded to the task management system. In the actual operation process, when the object release operation is performed, the file operation object in the target drag function and the task management system follow the same web page development specification. Since the file information of the object to be transferred obtained in the local file path can be directly recognized by the task management system, the automatic upload of the file information corresponding to the object to be transferred is completed.
[0043] In the embodiment of the present invention, in response to a received object drag operation, a target memory address of a target drag function is obtained from a pre-loaded target dynamic link library through a pre-configured address extraction function, a target drag function corresponding to the target memory address is called to automatically store the object to be transmitted in a local file path, and then the local file path corresponding to the object to be transmitted is accessed through the target drag function, and the file information of the object to be transmitted is obtained from the local file path, so that the file information of the object to be transmitted is automatically obtained, and there is no need to manually search for the local file path corresponding to the object to be transmitted step by step and manually extract the file information of the object to be transmitted, thereby improving the convenience of object transmission; in response to a received object release operation, the file information corresponding to the object to be transmitted is uploaded to the task management system, so that the object to be transmitted is uploaded in the task management system in a one-click manner; and, the file operation object in the target drag function and the task management system follow the same web page development specification, so that the task management system automatically recognizes the object to be transmitted; at the same time, the user performs the object drag operation and the object release operation, so that the user can complete various operations more efficiently and conveniently, simplifying the user's operation steps during the object transmission process and improving the user's use experience.
[0044] In one embodiment, before responding to the received object drag operation, the method further includes:
[0045] Obtaining the memory address of the original drag function in the initial dynamic link library through a pre-configured address extraction function as the first memory address;
[0046] Preconfigure the memory address of the target drag function as the second memory address;
[0047] The first memory address in the preconfigured import address table is replaced with the second memory address to obtain an updated target dynamic link library.
[0048] Among them, the initial dynamic link library can be understood as a pre-configured link library that stores the memory address of specific functions. The specific function can include the target drag function and the original drag function. The memory address of the original drag function can be extracted from the original dynamic link library. At the same time, as the memory address of the original drag function, i.e., the first memory address, is replaced and updated, the initial dynamic link library can be updated to obtain the target dynamic link library. The original drag function can be understood as a function that needs to be replaced. In the actual operation process, the original drag function can be a function used to perform an object drag operation, and the original drag function can be used to point to the function to be transferred. The first memory address is the memory address of the original drag function; the second memory address is the memory address of the target drag function. In the actual operation process, the first memory address and the second memory address can both be addresses dynamically allocated by the operating system during the program running process. Among them, the second memory address is the target memory address. The Import Address Table (IAT) is an important structure in a Portable Executable (PE) file, which is used to record the function addresses in the Dynamic Link Library (DLL) file being used. During the running process, the memory addresses of the functions called in the DDL can be written into the IAT one by one, so as to associate the instructions for calling the function with the memory address. A portable executable file refers to a common file format for executable files and dynamic link library files (DLL) used in an operating system, which can reduce the use of memory and disk space, and facilitate function updates and maintenance. The file structure of a portable executable file can include a DOS header, a PE header, a section table, and sections.
[0049] In an embodiment, before responding to a received object drag operation, the memory address of the original drag function and the memory address of the target drag function can be extracted in the initial dynamic link library through a pre-configured address extraction function, and the memory address of the original drag function is used as the first memory address, and the memory address of the target drag function is used as the second memory address. Then, the first memory address in the import address table is replaced with the second memory address to obtain an updated target dynamic link library. In other words, the memory address of the original drag function can be found, and the memory address of the target drag function can be replaced with the memory address of the original drag function to achieve the replacement of the memory address, and the one-click drag replacement of the memory address of the original drag function can be achieved without changing other memory addresses, thereby improving the efficiency of memory address conversion.
[0050] In one embodiment, the return value type, input parameter type, and output parameter type of the target drag function are consistent with the return value type, input parameter type, and output parameter type of the original drag function.
[0051] Among them, the return value type refers to the data type of the value returned by the function after execution. For example, the return value type may include string type, structure type, character type, etc.; the input parameter type refers to the data type of the parameter passed to the function for executing its function in the function definition. For example, the input parameter type may include integer type, floating point type, array type, etc.; the output parameter type refers to the data type of the output parameter of the function after execution. For example, the output parameter type may include character type, floating point type, array type, etc. For example, the return value of the target drag function may include at least S_OK success, DRAGDROP_S_DROP drag operation success, DRAGDROP_S_CANCEL drag operation cancellation, and E_UNSPEC unexpected exception, etc.
[0052] In an embodiment, the return value type, input parameter type and output parameter type of the target drag function are consistent with the return value type, input parameter type and output parameter type of the original drag function, which can ensure the normal execution of the target drag function and avoid the memory address of the object transfer function changing in the import address table due to inconsistencies in the return value type, input parameter type and output parameter type, thereby affecting the execution of the target drag function.
[0053] In one embodiment, the target drag function constitutes an Outlook plug-in and is installed in the Outlook client.
[0054] Among them, Outlook plug-ins refer to small program modules that add additional functions to Outlook or enhance existing functions.
[0055] In an embodiment, the target drag function can be encapsulated to obtain an Outlook plug-in, and the Outlook plug-in can be installed in the Outlook client. At this time, when an object drag operation occurs, the Outlook client can execute the target drag function to achieve one-click drag and drop of the object to be transferred, that is, the file information corresponding to the object to be transferred can be uploaded to the task management system.
[0056] In one embodiment, before accessing the local file path corresponding to the object to be transferred through the target drag function, the method further includes:
[0057] Convert the local file path into a data structure that matches the file operation object and assign it to the file operation object;
[0058] Assign the file operation object in the form of a data structure to the file access variable in the target drag function.
[0059] The data structure refers to a way of combining different types of data to organize, manage and store data more efficiently. The file access variable can be understood as a variable used to perform the function of accessing the local file path of the object to be transferred. The file access variable can point to the file operation object; the file operation object can be understood as an entity of a specific object or class used to process file-related operations. The file operation object can point to the local file path.
[0060] In an embodiment, the local file path can be packaged as a data structure and matched with a file operation object, the data structure is assigned to the file operation object, and then the file operation object is assigned to the file access variable in the target drag function in the form of a data structure. Generally speaking, it is possible to first define a data structure that converts the local file path to match the file operation object, assign the file operation object to the data structure, and then define a data structure that converts the file operation object to the data structure, and assign the file access variable to the data structure. In other words, when the file access variable in the target drag function is called, it can point to the file operation object, and the file operation object points to the local file path. When the file access variable of the target drag function is called, the local file path can be directly accessed, and the file information of the object to be transmitted in the local file path can be called. There is no need to manually open the local directory level by level to search for the file information of the object to be transmitted, which reduces the complexity of searching for the file information of the object to be transmitted and improves the efficiency of object transmission.
[0061] In one embodiment, Figure 2 This is a flowchart of another object transmission method provided by an embodiment of the present invention. This embodiment is based on the above embodiment and further describes the specific method of automatically storing the object to be transmitted to the local file path through the target drag function, and the specific method of accessing the local file path corresponding to the object to be transmitted through the target drag function. Figure 2 As shown, the method includes:
[0062] S210 . In response to a received object drag operation, obtain a target memory address of a target drag function from a preloaded target dynamic link library through a preconfigured address extraction function.
[0063] S220 , obtaining file information of the object to be transferred through a file extraction variable in a pre-created target drag function.
[0064] The file extraction variable can be understood as a variable for executing the function of extracting file information of the object to be transferred, and the file extraction variable can point to the object to be transferred. Exemplarily, the file extraction variable can be a variable pointing to the object to be transferred, for example, the file extraction variable can be pDropSource.
[0065] In an embodiment, in response to a received object drag operation, a file extraction variable in a target drag function may be called, and file information of the object to be transferred may be extracted through the file extraction variable. In an actual operation, the file extraction variable may point to a data retrieval interface of the object to be transferred, and data such as the object subject and object content of the object to be transferred may be extracted as file information according to the retrieval interface, and the file extraction variable may obtain the file information of the object to be transferred retrieved by the data retrieval interface.
[0066] S230: Automatically store the file information of the object to be transferred to the local file path.
[0067] In an embodiment, the local file path of the object to be transferred can be determined by the file extraction variable in the target drag function, and the file information of the object to be transferred can be automatically stored in the local file path. In the actual operation process, the target drag function can extract the file information of the object to be transferred, create a local file path corresponding to the object to be transferred, read the local file path, and automatically store the file information of the object to be transferred in the local file path.
[0068] S240. Access the local file path of the object to be transferred through the file operation object pointed to by the file access variable in the target drag function; wherein the file operation object points to the local file path of the object to be transferred.
[0069] Among them, the file access variable can be understood as a variable used to execute the function of accessing the local file path of the object to be transferred. The file access variable can point to the local file path or the file operation object. Exemplarily, the file access variable can be a variable that calls the file operation object, such as pDataObj.
[0070] In the embodiment, since the file operation object points to the local file path of the object to be transmitted, the local file path of the object to be transmitted can be obtained by accessing the file operation object. At this time, the local file path of the object to be transmitted can be directly accessed through the file operation object pointed to by the file access variable in the target drag function.
[0071] S250: Obtain file information of the object to be transferred from the local file path.
[0072] S260. In response to the received object release operation, upload the file information corresponding to the object to be transferred to the task management system.
[0073] In the embodiment of the present invention, the file information of the object to be transmitted is obtained through the file extraction variable in the pre-created target drag function, and the file information of the object to be transmitted is automatically stored in the local file path. Only then can the file information of the object to be transmitted be automatically saved, and the local file path of the object to be transmitted is accessed through the file operation object pointed to by the file access variable in the target drag function, so that the file information of the object to be transmitted can be automatically obtained, simplifying the user's operation steps during the object transmission process.
[0074] In one embodiment, Figure 3 This is a flowchart of another object transmission method provided by an embodiment of the present invention. This embodiment is based on the above embodiment, takes MyDoDragDrop as the target drag function, pDropSource as the file extraction variable in the target drag function, pDataObj as the file access variable in the target drag function, the created CFile object as the file operation object, GetProcAddress as the address extraction function, DoDragDrop function as the original drag function, email as the object to be transmitted, and the browser as the task management system as an example, to further illustrate an object transmission method. Figure 3 As shown, the method includes:
[0075] Install the Outlook plug-in in the Outlook server, and replace the memory address of the original drag function DoDragDrop with the memory address of the target drag function MyDoDragDrop in the Outlook plug-in. When the user presses the left mouse button (performs the object drag operation), the target drag function MyDoDragDrop can be executed to obtain the email title and email content of the email as file information, and automatically save the email file information to the local file path corresponding to the email. When the user releases the left mouse button (performs the object release operation), the file information saved in the local file path is uploaded to the browser.
[0076] The format requirements of the target drag function are as follows: the return value (HRESULT type), input parameter type, and output parameter type of the custom function must be consistent with the original drag function DoDragDrop function in the Windows system. In order to find the memory address of the original DoDragDrop function and avoid the memory address of the target drag function from changing in the import address table, the return value, input parameter type, and output parameter type of the target drag function must be consistent with those of the original drag function. For example, if the size of the return value of the target drag function and the number of bytes occupied by the name are inconsistent with those of the original drag function, the memory address occupied by the original drag function in the import address table will change, affecting other functions. HRESULT is the return value type in Windows programming, and its values include: S_OK success, DRAGDROP_S_DROP drag operation success, DRAGDROP_S_CANCEL drag operation cancellation, and E_UNSPEC unexpected exception.
[0077] The target drag function is a custom function, in which MyDoDragDrop is the name of the target drag function and HRESULT is the return value type of the target drag function; LPDATAOBJECT is a pointer type, pDataObj (file access variable) points to an object containing data such as the local file path; LPDROPSOURCE is a pointer type, pDropSource (file extraction variable) points to the dragged object to be transferred, and can obtain information such as the email subject and email content of the dragged email; DWORD is an integer type, dwOKEffects can indicate the scope of influence of the drag action, such as whether to delete the object to be transferred; LPWORD is a pointer to an integer type, pdwEffec can indicate the actual impact of this drag action on the object to be transferred after the drag is successful.
[0078] In one embodiment, the execution logic of the target drag function MyDoDragDrop includes: downloading the email to the local disk, and packaging the email in the local file path into a new structure (ie, CFile object) to replace the structure in the original drag and drop event (the event executed by the original drag function DoDragDrop).
[0079] Downloading the email to the local disk includes: obtaining the file information of the dragged object (email) through the file extraction variable pDropSource in the target drag function MyDoDragDrop, including the title and content of the email, etc. Creating a new file in the specified directory of the local disk and writing the file information can save the email locally.
[0080] Package the email in the local file path into a new structure (i.e. CFile object) to replace the structure in the original drag and drop event (the event executed by the original drag function DoDragDrop). The specific process is as follows: HGLOBAL and CFile are both file handles of the Windows system. However, unlike the original HGLOBAL, CFile is a type that can be recognized by the browser. The original input parameter pDataObj (file access variable) is a handle pointing to the original type HGLOBAL, and the content cannot be recognized by the browser. You can use the CFile constructor to create a new CFile object (file operation object) pointing to the local file path saved in the previous step, and let pDataObj (file access variable) point to the new CFile (file operation object. Therefore, in MyDoDragDrop (target drag function), the drag object is replaced with the email in the local disk, and when the mouse is released, the content pointed to by pDataObj (file access variable) can be guaranteed to be recognized by the browser.
[0081] In the actual operation process, in response to the object drag operation, a pDataObj (file access variable) is created. When the mouse is released (object release operation), pDataObj (file access variable) disappears. The local file path is assigned to the newly created CFile object (target drag function), and the CFile object (target drag function) is assigned to pDataObj (file access variable). At this time, pDataObj (file access variable) can point to the local file path.
[0082] At the same time, you need to find the memory address of the original DoDragDrop function (original drag function) of Outlook, and overwrite the memory address of MyDoDragDrop (target drag function) with the DoDragDrop function (original drag function). Specifically, you can use GetProcAddress (address extraction function) in Windows to get the import address table of the DoDragDrop function (original drag function) and put the DoDragDrop function (original drag function) into the method GetProcAddress (address extraction function) to get the memory address of the DoDragDrop function (original drag function), and then modify the memory address of the DoDragDrop function (original drag function) to the memory address of MyDoDragDrop (target drag function). At this time, you can get the corresponding portable executable file and update the target dynamic link library.
[0083] By default, when an object drag operation occurs in Outlook, DoDragDrop (the original drag function) is executed. Through the above steps, DoDragDrop (the original drag function) is replaced. Therefore, when an object drag operation occurs, MyDoDragDrop (the target drag function) will be executed instead.
[0084] The target drag and drop function and the portable executable file can be combined into an Outlook plug-in and installed in the Outlook client to implement one-click drag and drop of emails to the ITM management system web terminal.
