Try this:

COLORREF colour = RGB(r, g, b);

where r, g and b are three colour components.

For printing in hexadecimal mode:

printf("%06X", (DWORD)colour);

For obtaining red, green and blue components back, use GetRValue, GetGValue and GetBValue.

CString str;
str.Format("%02X, %02X, %02X", rVal, gVal, bVal);

Somethings seem HARD to do, until we know how to do them.

Messages when windows lose focus

Hi All,

I would like to write an application which should receive a message when the current active window loses focus. For example, consider MS-Word is active now. As soon as somebody opens IE then word window will lose its focus. At this event my application should get a message. And after sometime when this IE gets minimized I should get another message. Basically my application should be able to receive messages when different window events happen.

Is this possible? Can somebody give me some information?

Thanks,
Sandeep

Do it this way,
Get the active window and store in the a variable :- activeWind.
Now keep checking the GetActiveWindow() window against the activeWind, If it differs, take that as an Event, and update your activeWind will this help you?, but there should other simpler ways Smile | :)

Assure that the .h file is with you , and if you use < > it searches the standard library directories. If you use "", it searches the local director. If you are not sure what to do, do this, copy the .h file to the local folder where you keep the other .cpp .h files of your project. Now use #include"sdf.h" here it can never say "cannot find the file " again.

print a bitmap

4-Jun-06 23:07

both Monitor and printer are set to MM_LOENGLISH

GetDeviceCaps(RASTERCAPS) supports for:

RC_BITBLT : both
RC_STRETCHDIB : both
RC_DEVDITS : monitor only
RC_STRETCHDLT : monitor only

Result:
monitor can display bitmap by 4 functions properly.
but Printer can display bitmap only by StretchDIBits() function, BitBlt() does not work.

who knows why?
