Hi,
I am trying to play a bit with arm-wince-mingw32ce (0.50-cygwin).
I'd like to compile a piece of code which does "screen rotation".
It is based on the "Pocket PC Screen Rotation" example code:
http://www.codeproject.com/ce/pocketscreenrotation.asp
and the "Rotating the Contents of the Screen" explanations:
http://msdn2.microsoft.com/en-us/library/aa452713.aspx
The detailed explanations about ChangeDisplaySettingsEx can be found here:
http://msdn2.microsoft.com/en-us/library/ms908108.aspx
When I try to compile the code, I get a message that the symbols related
to screen orientation are not defined: DMDO_0, DMDO_90, DMDO_180,
DMDO_270, DM_DISPLAYQUERYORIENTATION, DM_DISPLAYORIENTATION.
So, I am trying to define them myself:
---------------------------------------------------------------------
enum DMD
{
DMDO_0 = 0,
DMDO_90 = 1,
DMDO_180 = 2,
DMDO_270 = 4
};
enum DM_Fields
{
DM_DISPLAYORIENTATION = 0x00800000L,
DM_DISPLAYQUERYORIENTATION =0x01000000L
};
---------------------------------------------------------------------
Can anybody verify that it is correct? (I have also seen source code, in
the Internet, in which people define, for example, DMDO_270=3, and/or
DM_DISPLAYORIENTATION=0x00000080.)
However, then the linker complains that the ChangeDisplaySettingsExW
function is missing (I'm new to this whole business, so excuse my silly
question - why, if I use ChangeDisplaySettingsEx in my source code, the
linker complains about ChangeDisplaySettingsExW? What's this "W" in the
function's name?)
Best regards,
Thanks in advance,
Jacek.
