// Hmmm. Normal, interpreted as Null Terminated ("**"), strings prints no problem, as does
// a standard char array buffer. The question is, then, how do you get a STRING
// resource to format as char? FormatMessage does not seem to do the trick.
// Or I am not using it correctly. There is only
// some stuff in Japanese about it on MSDN, so
// I have no reference....
//
// Just a note, the STRING resource, that comes from a *.txt file, is NOT stored with the
// *.exe as letters, but apparently as its character (scan?) codes. Ie; non hexadecimal numbers.
// I am wondering if the conversion to characters is required in a separate function, even though
// a scant, indirect reference seems to promise that this
// is not needed when using FormatMessage() function.
//
// So, my doubt: Is the way I am embedding a STRING resource the right way (ie; as a txt file)?
// Is there another way? Is this possibly the problem?
BitBlt(hdc, 0, 0, prc->right, prc->bottom, hDcBuffer, 0, 0, SRCCOPY);
SelectObject(hDcMem, hbmOld);
DeleteDC(hDcMem);
SelectObject(hDcBuffer, hbmOldBuffer);
DeleteDC(hDcBuffer);
DeleteObject(hbmBuffer);
}
What I have already covered (please note the comments in the code, too).
