When I use the following code nothing appears if the ZBuffer is enabled... The display is in a picturebox located within a VB form... Can anyone see what I am doing wrong... so that I can use a Z buffer.
In the Debug Window it says it is choosing the 32 bit Depth buffer but i have tried it with all the buffers to no avail
