Transparent forms on video

[Lunatic3]

I am quite new to graphics in VB and currently using VB.NET to draw a grid on a transparent form, and this grid will be callibrated and used for some real world measurments. Everything is ok except that we are going to put this grid over a live movie captured from a device (microscope) and do the measurments, but the transparency of the form makes the grid to flicker and the movie to be played slow How can i avoid this? Or maybe I have to do the proccess on still images?

Don't use the SetLayeredWindowAttributes API, that is the one used by VB.net to draw forms transparent.

Ok, so how to make my form transparent then?

I know, there is no other descent way to make your forms transperant. If you want a raster over your movie to messure, you should import the movie/stream into VB. Then you can do a lot more with it.

Thank you very much, you seem to know much about it, so i would be glad if you help me more. I am thinking of building a small interface for capturing video from source and put the grid over that.

Thanks again!
