    Unhappy Generating *Keyboard Events* thru programming ???

    Hey guys

    I want to create a simple program to post some specified key events on a aregular basis for win32, but i do not know what libs and methods to use. The overall strucuture will be as follows :

    =============
    Code:
    int main()
    {
        while(true)
        {
            //post a <num_pad_5> event
            //wait 100ms
            //post a <num_pad_enter> event
            //wait 3000ms
        }
    }
    =============

    Thats it. Please guide me and tell me what libs and methods to use. I am using VC98. It will be great if you can tell me some links too, but basically I am looking for some straight forward lines of code.

    TY

    I'm not sure there is a straightforward way to do what you want. I encourage you to be very specific about what you are trying to do. For example, if you want to monitor keystrokes resulting in ASCII/unicode chars then that program will be different than if you want to monitor all keystrokes, whether they result in a char being displayed or not (for example the tab key, shift key, arrow keys, etc.) For the former you could look at individual char in the input buffer and whenever a certain char is encountered do a certain task. For the latter you may want to monitor virtual key (VK) values, I believe they are in winuser.h. To have the program wait for a predetermined duration before proceeding I'd suggest looking up Sleep(), I believe it is in windows.h.


    Who knows, you might end up with something like this:
    Code:
    while(1)  //an infinite loop
    {
       if(kbhit())  //non-std way to recognize keystroke happened
      {
    	 if(VK_Q)  //if key hit was q 
    	   //do something
    	 else if(VK_ALT) //if key hit was Alt key
    	   //do something
    	 .
    	 .
    	 .
       }
       Sleep(100); //pause program for 100 milliseconds
    }
    You're only born perfect.
