Hi!

We need very fast capture screen code or dll(may pay).
We do screen capture through Gdi32 or Graphics.CopyFromScreen, but maximum speed of screen capture very low.

Ok, so what is your question?

We are in search of technology that makes the fastest screenshot. We tried Win32 and Graphics. On average computer screen capture rate of approximately 40 ms (25 fps). Is there a technology which allows to make it faster?

That's good performance for GDI.

Every piece of code which is "slow" could be done even slower. So, how can we know your way of doing so? Let me tell you: screen measured in pixels, even big screens, are miserably small, capturing a bitmap from one happens pretty fast (who knows what speed do you expect, but the delay is almost not perceivable by a human). So, it means that you screw up something pretty well... Who knows what, without seeing your code?
I hope you did not do anything like GetPixel or SetPixel... :-)

Hi Sergey!
Now we are talking only about the screenshot, without working with him

Excuse me, who are "we"? I'm not talking about any separate part of it. We are talking about nothing now, just because you don't provide any information useful to help you, so far. You can also see available solutions of this problem at try to use it.

Well, "very fast" and GDI+ should never be used in the same sentence. The two are multually exclusive.

What are you doing that you think you need to grab the screen so fast. I take it you're doing some remote desktop application or making a video out of these screen grabs??

Perhaps my solution will help you. It is multi-threaded and the number of threads dedicated to polling the screen are configurable. I will even sell you rights to use it since it is licensed for non-commercial use.
