Hi frineds,
I have used WDK(7600.16385.1) mirror driver but i.e. only shows a simple blank window but I wanted to copy complete desktop into that window. I tried some experiments but could not get success. I saw in kernel mode driver drvCopyBits()/DrvBitBlt() are not copying data from source surface to destination surface. Is this the reason why window is showing blank?

I am very new to mirror driver so any help or any pointer will help me a lot.

If you have any sample code which will copy active desktop into a new window/file, please let me know?

Friends, I have heard that this community is very active, Please help me out.

Currently I am trying to implement DrvTransparentBlt(). I have read, purpose of this function is to copy data from device controlled surface to GDI surface and vice versa. But I have no clue how to implement it. Any sample code will also help me to understand what all calculation I need to do inside this function.

My main intension is to grab the display/any activity at user level and send it to driver through GDI calls.

Any source of information will help me a lot.

Looking forward to your response.
