Cegetdev displays 320x240 on a VGA device

Hi Everybody!

Cegetdev.exe sample application (included in EVC4.0 samples) displays
these values on a HP iPAQ hx4700 (and on Pocket LOOX 720 also):

HORZRES=240
VERTRES=320

But, it is not the truth because these devices have 640x480 screen
resolution.

Cegetdev.exe uses GetDeviceCaps function and this function returns the
wrong value.

How can I get correct screen resolution? I don't know other way than
GetDeviceCaps func.

Any idea?

By default, applications compiled using the Pocket PC 2003 SDK or earlier
are run in a legacy mode where the OS pretends to be 320x240 and does
automatic pixel-doubling to properly display on 640x480.

To get out of this legacy mode, your application needs to be marked as being
resolution aware. There are whitepapers in the 2003 Second Edition
Developer Resources kit explain how to do this for both native and managed
code.

how about GetSystemMetrics (CE .NET 4.2) ?

int iWidthScreen = ::GetSystemMetrics(SM_CXSCREEN);
int iHeightScreen = ::GetSystemMetrics(SM_CYSCREEN);

All APIs will return 320x240 unless you mark your application as being
resolution aware. See my previous response in this thread.

Not quite all:

ExtEscape(dcH,GETRAWFRAMEBUFFER,0,0,sizeof(RAWFRAMEBUFFERINFO),(CHAR*)&rfbi);
