Hi,
i've to write an installable driver, similar to a webcam driver, that
makes screenshots of the desktop and sends them to output. I've no
problem with the
screen capture and i know how to create an installation driver for
windows, but i don't know the way the driver changes messages and
frames with the applications. The installable driver must be seem as a
standard webcam driver (but it doesn't receives frames from the
device, it generates them capturing the desktop).
Could you help me?
Thanx a lot
Tommy

take a look at

WMEncoder seems ok to capture the desktop. but I have no idea about the driver yet. If anybody knows about how to encapsulate this capture into a driver, pls, let me know.

I'm digging deep into the code of the Testcap sample provided in the windows DDK. The problem right here is that Testcap captures video from a hardware capture device and I need to make it capture the screen. Inside Testcap there is a function called imagesynth(). I guess that in there the output colorbars are generated since the function does not returns something.
I really need to make this **** work since it is for my practice period. Anyone who has some sollution can reach me here or private at dikkefritmayo at hotmail dot com.
I guess Tommy also been inside the testcap driver so any experience from you would be welcome.
Let's say that if we manage to develop a stand alone driver, with no app to control it, thats is able to send the screen to an app like flash we developed something amazingly new and very welcome in the world of screen sharing. I don't know if you guys are familiar with the story about Macromedia Breeze and its screen sharing function. Google a bit around and you find out that MM cut off the possibility to capture the screen and send it to the Flashcom Server just because Breeze was comming out and they expected to many competition from other developers. Breeze works now with the Breeze player which is a adapted Flash player.
So please help me develop this stuff so you, me and thousands of users can show their *** to MM.

All last summer I spent trying to create my own screen capturing program but the result seemed to be worth then the existing programs show. So I gave up the idea and now use Screen Vidshot (http://www.geovid.com/Screen_VidShot/)... Its much more convenient to use a finished tool then trying to create your own. There are numerous programs of all kinds......
May be you should try to find an application rather then create your own?
IMHO.....

Hi, Tomzie,
Did you solve your problem. What you are developing is exactly what I want. I am also trying to develop the same drive so that I can share my desktop through flash communication server. Can you post me a copy of your code. my address is: li_yonglin at yahoo dot com
Thanks!
