Microsoft sample mirror driver causing Excel problem

NTDEV

Hi,

I’ve been trying to develop a mirror driver for Windows XP, but
unfortunately the sample mirror driver that Microsoft provides in the
DDK (Windows Server 2003 SP1 DDK, and previous XP DDK) stops Excel from
working - once the driver is installed and has been used, any attempt to
start Excel (even an empty worksheet) causes a dialog with “Not enough
system resources to display completely”.

I’ve seen postings in other forums from people with the same problem,
but no answers. If anyone knows how to fix this, or has any suggestions,
I’d be very grateful.

Thanks,

Frances

Hi Frances,

The excel problem is due to the DDI calls returning FALSE in the sample mirror driver. To solve the problem, please change following functions to return TRUE in enable.c file :

DrvCopyBits
DrvBitBlt
DrvTextOut
DrvStrokePath

Now rebuild the driver, replace the .dll in system32 directory and reboot your PC.
That’s it, you can start playing with Excel again!

Cheers,
Avinash
