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?
