nVidia NvGetDisplayInfo

[twanvz]

I'm trying to make an exe file eventually, for doing the following:

1) get both connected monitors cloned

2) set the "analog display" as primary display

the first step is not a problem, I did this:

rundll32.exe NvCpl.dll,dtcfg setdelay pre 5000

rundll32.exe NvCpl.dll,dtcfg setview 2 clone

rundll32.exe NvCpl.dll,dtcfg setview 1 clone

rundll32.exe NvCpl.dll,dtcfg setdelay pre 0

that's not a big problem.

but now i deed the tool to detect which display is called "analog display".

i'm reading nvidia site manual (page 36) and I see I have to use these options:

char szDisplayName[MAX_NVDISPLAYNAME] > to see what are the monitor names.

DWORD dwWindowsMonitorNumber > to see if the analog display is called monitor 1 or 2.

BOOL bDisplayIsPrimary > to see if the analog display is the primary display.

then with DTCFG primary make the analog display primary.

but I don't know how to use these commands.

because the first above 4 lines, I just put it in a batch file and then converted it to an exe.

but how do I get the nvidia tool to tell me which display is the analog display and then set it as primary?
