    Just store a collection of rects for each key and cycle through each one to determine which one has been touched.

    in C++ I would use a lot of windows (maybe owner-draw buttons) and simulate key messages to fool any app into thinking it's a real keyboard

    well if you get the touchscreen input just like a mouse input it wont be hard at all
    just a bunch of buttons and a txtbox that would get the new letter for each button....
    well but I guess you have some other problem so what do you need?

    I just wanna know if there is any kind of a VB control which enables the use of an on-screen keyboard or any application which can be used in VB 6.If yes where can i find it... if not can someone provide me with a piece of code through which i can make the above idea provided, functional. ( the idea was to create buttons and a textbox) Cheers

    so youve got a problem with your vb application, sending the keys they press to the program you want, I kind of faintly remember a sendkeys API Function to send ascii data to another application as if the keyboard pressed it.

    i'm at college at the minute but whenIi get home I will see if I can find it

    This thread shows you how to simulate KeyPresses it discusses send keys and keyb_event API calls, you will have to look the declares for them in the API viewer.

    http://www.vbforums.com/showthread.php?threadid=155846

    remember you will have to return focus to the application the keys are being pressed to or they will be sent to your onscreen-keyboard

    keep in touch because I will help with project or if you dont want I would like to see finnished thing
