i had managed to display something by first getting the panel's windowsHandle(HWD),then call the MIL funciton to display the streaming image on the panel. but the image comes out flickering as the panel is trying to come ontop of the image, hence the flickering as the panel and image are overlapping each other. i would like to know if i can feed a streaming image buffer from a non NI video grabber (Matrox for this case ) onto a panel in CVI Labwindows. Thanks for your kind attention.
