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!

Thus users can easily zoom in and out simply by using Ctrl+Scroll button(Mouse Middle button), just like AutoCAD.
