Hi Timo,

Many thanks, attached is the project built with Poasm. There are some minor modifications in the code, I hope you don't mind.

Running the executable, I get :


--- Code: ---0 x 0
--- End code ---

TimoVJL:
Thanks
In my system it gave 1920 x 1080

EDIT:
libs are useful for this testbed

Hi Timo,

Thanks, I tested your 32-bit version of msvcrt.lib. The result is the same on my Windows 7 Sp1 64-bit system :


--- Code: ---0 x 0
--- End code ---

EDIT : Here is the fixed version following Timo's recommendation to set the driver name to NULL.


--- Code: ---1366 x 768
--- End code ---

TimoVJL:
My system is also Windows 7 SP1 x64.
Those msvcrt.libs was for common usage for those, who don't have them currently.
