Wait for Monitor

[Glenn9999]

Is there a function/way of some kind to be able to tell when a computer monitor has completed a draw to its surface? For example, if I wanted to determine the response time of it?

are you refering to Vsync or do you mean when the graphic card has finished a drawing order?

When the graphic card has finished the draw order and the picture/whatever is up on the screen. Say I do the order to draw a bitmap to the computer in full screen, the code to prepare it is done, and the code is issued to draw it. I want to know if/how to know when the drawing operation is completed.

I got the chance to look into it. VREFRESH in GetDeviceCaps gets me what I want to know. The problem is it's for NT/2000/XP only...how would I do it within 9X?
