Problems solved by technology
[0007] Although the above two methods both achieve the purpose of converting the form of the ActiveX component into the MDI sub-form of the main program, they both need to modify the main program or the ActiveX component, destroying the structure of the original program, and the conversion details are cumbersome and error-prone ; Moreover, each ActiveX component needs to be modified separately, which is not reusable

Embodiment Construction
[0015] The embodiment of the present invention provides an MDI conversion method and a related device, which are used to convert the form of the ActiveX component into the MDI sub-window of the main program.
[0016] see figure 1 , an embodiment of the conversion method of the multi-document interface in the embodiment of the present invention includes:
[0017] 101. Subclassing the form of the main program;
[0018] After the main program is started, the conversion device of the MDI subclasses the form of the main program.
[0019] Windows is a message-based system. Messages are passed between Windows objects; subclassing technology is used to intercept messages between forms or controls. Subclassing is the operation completed before the message reaches the target form. The intercepted message can be retained or modified, and the message can be sent after corresponding processing. Simply put, subclassing is to create a new form message handler and insert it before the orig...

An embodiment of the invention discloses a multiple-document interface conversion method and a related device which are used for converting a window of an Active X component into an MDI (multiple-document interface) child-window of a main program. The multiple-document interface conversion method includes subclassing the window of the main program after starting the main program; loading the Active X component which is a functional attachment expanded in the main program if the Active X component is called, and subclassing the window of the Active X component; creating the MDI child-window in the window of the main program and subclassing the MDI child-window; embedding the window of the subclassed Active X component into the subclassed MDI child-window, and displaying and operating the window of the Active X component as the MDI child-window of the main program. Besides, the invention further provides the related device for implementing the multiple-document interface conversion method.
Description
technical field [0001] The invention relates to the field of computers, in particular to a method for converting multiple document interfaces and related devices. Background technique [0002] In order to facilitate the user's operation, existing software generally supports Multiple Document Interface (MDI, Multiple Document Interface) technology, so that the user can freely switch among various sub-windows without closing the current window. [0003] ActiveX component refers to an executable code or program. Multiple ActiveX components may be inserted into the main program at the same time, and the form in the ActiveX component and the main program that calls it are fused into an MDI sub-window, so that the user can enter the main program in the main program. In the form, click the MDI sub-form list menu item in the "Form" menu to switch and operate the form of different ActiveX components. [0004] In the prior art, the form of the ActiveX component is mainly converted in...
