Abstract
The invention discloses a method for implementation of a universal keyboard lock function, which includes steps: calling a derived function from a dynamic link library and setting up a global hook within a system range; and judging whether each user's keying intercepted in the dynamic link library is an unlocking key combination or not, if yes, stopping intercepting and unlocking, and if no, directly ignoring the keying which is transparent for an operating system. An unlocking key predefined by a user is directly written into a registry, and an original file system of the user is unchanged while unlocking failure caused by file misoperation of the user can be avoided. A WIN32API (application program interface) is used in the method without depending on any other component, the capacity of a final program is greatly reduced, and the capacity of all finally released program files cannot exceed 64KB.
Description
Technical field
The present invention relates to a kind of method of keypad lock function, be specifically related to a kind of method that is implemented in the keyboard lockout function on the WINDOWS operating system to universal computer.
Background technology
In the real life, need the temporary close keypad function sometimes, the ongoing task of user is caused interference to prevent the keyboard misoperation.Traditional similar software is mainly considered from security purpose, in the locking keyboard, can lock mouse simultaneously, and What is more directly locks desktop, and the user just can't normally carry out other operation (such as watching video) like this, has therefore brought very big inconvenience.
Summary of the invention
The objective of the invention is to overcome the above problem that prior art exists, a kind of implementation method of universal keypad lock function is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
The implementation method of universal keypad lock function may further comprise the steps:
Step 1) is called the derivative function in the dynamic link library, and the overall hook in the system scope is set;
Step 2) whenever intercepting user's button in the dynamic link library, can judge whether it is the release Macintosh, is then to stop interception, release; Otherwise directly ignore this button, uncared-for button is transparent to operating system.
The invention has the beneficial effects as follows:
The present invention directly writes registration table with the locking key of separating of consumer premise justice, neither changes the original user file system, can avoid the user misoperation file to cause the release failure again.In addition, program of the present invention is used WIN32 API fully, does not rely on any other assembly, has dwindled the volume of final program widely, and all program file volumes of final issue can not surpass 64KB.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of instructions, below with preferred embodiment of the present invention and conjunction with figs. specify as after.Embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 master's dialog box of the present invention synoptic diagram;
Fig. 2 system tray synoptic diagram of the present invention.
Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the present invention.
The implementation method of universal keypad lock function may further comprise the steps:
During this program of step 1) operation, detect this program and whether move, withdraw from if moved then;
Step 2) the locking key setting is separated in inspection, if move this program first, then writes default setting to registration table;
Step 3) shows user interfaces such as dialog box, tray icon, and according to step 2) in the parameter that reads, window controls such as CheckBox and Edit are set, as shown in Figure 1;
Step 4) is called the derivative function in the dynamic link library behind user click Lock button, the overall hook in the system scope is set;
Whenever intercepting user's button in the step 5) dynamic link library, can judge whether it is the release Macintosh, is then to stop interception, release; Otherwise directly ignore this button, uncared-for button is transparent to operating system;
Other function of step 6): the user can be provided with, preserve and separate locking key; Right button can be selected to quit a program on tray icon, and is as shown in Figure 2.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (1)
1. the implementation method of universal keypad lock function is characterized in that, may further comprise the steps:
Step 1) is called the derivative function in the dynamic link library, and the overall hook in the system scope is set;
Step 2) whenever intercepting user's button in the dynamic link library, can judge whether it is the release Macintosh, is then to stop interception, release; Otherwise directly ignore this button, uncared-for button is transparent to operating system.
