I need to get faster algorithm to capture from a secondary system and to display on mine. Alike a remote control but just to see , without control this system.

I intend to grab from the second monitor images and to stream it with DSPack library to mine. ( to let the teacher to see what do the students on their systems )

Can somebody to support me with tips how to capture faster the images from the second monitor and to prepare these to be streamed?

<b>It's possible to stream the second monitor video signal (not to capture every second a new desktop image ) ?</b>

I will like to have a real image from the second system monitor, alike that  this  monitor is connected directly to my system.

Can be find on net sample projects? I have one but big delays onrefreshing (long time spend with capturing)

Best regards,

P.S. Suplimentar points available

I know this isn't what you asked, but..... have you considered all other options first? Writing a whole new application for this seems unnecessary, if it's the results that you want, rather than the development experience...

Something like the free RealVNC lets you monitor and control a remote PC - that's reasonably quick - and I think the source is available.

There are already various companies offering similar stuff, specifically for teacher/student situations.

And have you considered simply using some form of monitor splitter box - especially if you're in a teaching classroom environment..

You're likely to be hard pushed to find a Delphi version. Isn't the C++ understandable enough to give you some ideas? I think they've various white papers and other documentation that describe how it all works, too.

There is a Delphi translation available, but the source hasn't been updated for a while: http://delphivnc.sourceforge.net/
