The Crosshair sample program is based on our PXCBASIC Visual Basic example. The Crosshair program demonstrates a simple technique for generating a destructive overlay using the GetPixel and PutPixel functions. You can find the actual routine for generating the crosshair (DrawCross) at the bottom of the display form (frmDisplay) in this example. This program will work for both PXC200 and PXC200A boards.

This sample was built for Windows NT, 2000 and XP. If you are using Windows 95, 98, or Me, you will need to delete the module PXC2_NT.BAS and insert the module PXC2_95.BAS. The modules for each operating system are listed below.
