Thread: Mirror Driver

I am trying to write an app that mirrors a portion (or rather two) of the pr
imary display onto a seconday monitor in real time. In its final instance t
he user will need to be able to define the clipping region from the primary
display and then the destination location of the mirrored data on the second
ary monitor.

I am a visual basic programmer but realise I will need to do this in c/c++ b
ut I dont mind learning!!!

After much searching I have come up with two methods, one the bitblt and the
other a mirror driver. Unfortunately I have no idea what either mean. I k
now there is a sample on the Windows DDK which uses a mirror driver but I ca
nt find it anywhere for download and dont want to spend 199 dollars unless I
m sure it will do what I want.

Does anyone have any ideas/advice but preferably sample code that will do so
me or all of the above.

Many thanks in advance.

Start reading basic c++ tutorials and learn the basics.

You could probably do this in VB. Look up "screenshot code" to copy from the original screen and BitBlt the result to a destination window. Repeat several times per second.

The BitBlt function simply copies an image from a source device to a destination device. A device may be a screen, printer or memory.

The windows DDK isnt $199. I got my copy off MSDN for about $20 if I remember correctly. A note of warning though, unless you are very very comfortable with C, writing a driver will not be an option for you.
