Question

When we go to Control Panel -> System, the detail shows a number of details like windows experience index including “Pen and Touch: Pen and Touch Input Available with x Touch Points”.

Is there any way to know this information from .NET/C# application? Basically I want to know whether the application can use touch/gestures.

Answer 1

If you can call GetSystemMetrics you can find this information. MSDN shows how to do it. Test for the multi-input and stack-ready bits.

I know you’re asking about C#, but in C you use:

int value = GetSystemMetrics(SM_DIGITIZER);
if (value & NID_READY) { /* stack ready */}
    if (value & NID_MULTI_INPUT) {
        /* digitizer is multitouch */ 
    }
}
