The pen on a tablet functions like a mouse. You can get the position of the mouse/pen by using the Call library function node (Connectivity -> Libraries and Executables) in the functions pallete. You can use the user32.dll to call the GetCursor method for the pen position.

Thank you,But there is a predefined function in labview to get position of courser of mouse, can I use this function to pen?

Yes, you can. It basically uses the same backhand architecture I mentioned in my last post.
