    Re: check whether mouse is plug in or not

    If you just want to know whether any mouse is installed (as opposed to specifically a USB mouse) then you can use

    Code:
    bool IsMouse()
    {
         return GetSystemMetrics(SM_CMOUSEBUTTONS) > 0;
    }
    See http://msdn.microsoft.com/en-us/libr...=vs.85%29.aspx

All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality.
