overlay during continuous acquire

[dcimma]

Are there any examples of doing overlays while continuously acquiring images?   Trying to do a simple crosshair overlay on a live image in VB.net.  Have been able to do it using ImageAquired event but the results aren't that great... lines (crosshairs) tend to flash.   Anyone know of a way to do this and get cleaner display?  I am re-drawing the crosshairs on every event (frame).

I don't know of example code that does exactly what you are looking for. You may already know but the example VB.net code is located at the C:\Program Files\National Instruments\Vision\Examples\MSVB.NET folder. If this doesn't have code that you are looking for maybe you can check ni.com/community. This is a location made for posting example code for anything related to National Instruments. I'm not sure if there are any NI Vision examples in VB.net yet but if you create code that works or find some from someone else feel free to post it there.
