    Shall we guess the OS/Compiler you're going to use to attempt this?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Are you using the MFC library, the native Windows API or some other library to handle your graphics?

    In native windows the message is VM_LBUTTON_DOWN or VM_RBUTTON_DOWN.

    In MFC, use CWnd::OnLButtonDown (or OnRButtonDown). http://msdn2.microsoft.com/en-us/lib...9k(VS.80).aspx

    Other libraries obviously have their own way to deal with these things.

    Thanks for the reply, not sure which to use.

    Basically i would need the mouse clicks to be monitored outside of the client window, well there wouldn't even be a client window. I want to be able to monitor everytime the user clicks the left mouse button within windows xp. I'm writing an automated test app, i am using a combination of Java robot api and JNI, java does not support mouse click monitoring outside the VM, so i have gone native.

    Yes, I beleive you can create a handle for the desktop itself, and using that you should be able to "see" mouseclicks all over.

    SetCapture.

    Thank you for your help.

    I have been experimenting with HOOKPROC. I will also look into SetCapture. Using either of these i think my problem will be solved.

    I have tried googling my next question but with no luck, i dont think i am using the correct terminology, but basically i was wondering if i could open the application i am testing within the application i am writing. Is this possible?

    Yes, ShellExecute or CreateProcess will create a new process that your current process is "the owner of".

    Cheers for your help.

    I have a question concerning the following lines of code:

    Code:
    hinstDLL = LoadLibrary((LPCTSTR) "c:\\windows\\sysmsg.dll"); 
    hkprcSysMsg = (HOOKPROC)GetProcAddress(hinstDLL, "SysMessageProc");
    These two lines of code are from the MSDN website, i am confused with them though, firstly the .dll "c:\\windows\\sysmsg.dll" does not exist, i cant find it in that directory.

    Also "SysMessageProc", is this a method i should implement in my code, or is this a method within the .dll .

    Thanks Again.
