Implementation method and system of virtual input device in driver layer

Abstract

The invention discloses a method and a system for implementation of virtual input equipment in a driving layer. The method includes: calling a system application programming interface to set up virtual input equipment, and mounting the virtual input equipment on the driving layer; recording a function address of system input equipment into an equipment expansion structural part of the virtual input equipment to enable the driving layer to automatically obtain the function address of the system input equipment; acquiring an input data structural element sent by an application layer to the virtual input equipment; and allowing the driving layer to use the obtained input data structural part to control behaviors of the virtual input equipment according to the equipment expansion structure part recorded in the virtual input equipment. By means of the method and the system for implementation of the virtual input equipment in the driving layer, the virtual input equipment can be controlled when messages of the virtual input equipment are shielded by software.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and system for realizing a virtual input device at a driver layer. Background technique [0002] Under Windows 2000, almost all I / O is packet-driven. Each job command describes a single I / O operation. This command tells the driver what to do and tracks the request through the I / O subsystem. The progress of these commands is encapsulated into the form of an input request package (Iuput Request Package, referred to as IRP). When an I / O system service is issued (such as a request to create a file or read a file), the I / O manager will pass Construct an IRP describing the request, and pass a pointer to the IRP to the device driver to start processing the request. If the OS fully describes an I / O request to the I / O manager and device driver, then the information stored in the IRP can serve this purpose. [0003] The filter layer driver is an intermediate layer driver that intercepts...

Problems solved by technology

WINIO sends data directly to the physical mouse. However, when the program sends data, it is also possible to manually operate the physical mouse or keyboard, which may cause data confusion, the effect of the mouse flying all over the screen or the effect of typing wrong characters.

[0008] In summary, for the problem of being unable to control the mouse or keyboard under the situation of shielding the API function of controlling the mouse or keyboard, no effective solution has been proposed in the prior art
