    Get size of client window

    Hi I am trying to find some function which would return a lenght and height of current window in pixels... I tried GetSystemMetrics() but it didnt work properly...

    Is there any other way how to find out these two values?

    Thx

    Isn't there a getClientRect type function?
    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.

    Yes. And GetWindowRect. A search would've found both.

    See also SystemParametersInfo(SPI_GETWORKAREA flag) if you just need to adjust GetSystemMetrics results to account for the taskbar.

    Thanks for that tidbit Ken, I knew there had to be a simpler way. Up until now, I had been using:
    y = GetSystemMetrics(SM_CYVIRTUALSCREEN) to get the height of the window
    hTaskBar = FindWindow("Shell_TrayWnd") to find the handle to the taskbar/tray
    GetWindowRect(hTaskBar, &trayRect)
    and finally,
    WorkAreaY = y - (trayRect.top - trayRect.bottom)

    While were on the topic of insanely complex methods of handling relatively simple problems, would you know a simple way of how to set a window's client size? So far I've been using SetWindowPos(), but since this uses total size, I have to then compensate for title bar thickness by calling GetTitleBarInfo().rcTitleBar.(bottom - top) first :S

    AdjustWindowRect() //calcs the window size based on the supplied/required client area and window style.

    This can then be passed to SetWindowPos() ect.
