virtual display capture driver for headless system

[Stefan Pflaume \(XPe\)]

Hello,

I am thinking about programming a virtual display driver, which is able to
save a BMP to a local HD or to a mapped network drive, triggered by Telnet
or a timer.

So it should be possible to get the screen output of a headless device (e.g.
no graphic card) during FBA or during normal operation mode.

Any suggestions, ideas or interests to/in that?

(Maybe someone has already done this?)



Kind Regards

Just wondering why did you want to implement that screen capturing functionality in a display driver?
Since you are interested in GUI capture you can create a simple Win32 app that will capture the screen images. The app can be
implemented and run as a service or userinit type of app. If it is a user mode app, then the full power of Windows GDI interfaces
(DIB, files, timers) is available to you and the screen capture function is much easier to implement.

Quite frankly, I don't see much of the value in capturing screens during FBA. FBALog, setupapi log and other logs are often enough
to trace problems on headless systems that may appear during FBA.
During normal system operations you can remote in (RDP or other remote management/administration tools like VNC, RAdmin, etc.) and
see the screen "live".
