Using touchscreen with LabVIEW

[Gael Anquetil]

Hello,

I am trying to use classical touchscreen moves on my LabVIEW application. The problem is I really don't know how read the information coming from Windows indicating the type of move (zoom rotate, span,...)!

I tried to use the Windows message queue library (using user32.dll) with the message WM_TOUCH and WM_GESTURE but nothing works. I don't know if it's compatible...

Does anyone tried to do this? 

Thanks for your help!

It probably isn't going to be easy doing it yourself.  The simple touch screens I've used just simulate mouse interaction so multiple touches get registered as multiple mice, but there are several caveats associated with it.  I'd suggest looking into one of the toolkits for this type of thing.  I've never used one but it is where I'd start if I had to do anything advanced. I thought NI had one but I can't seem to find it.
