How can you select a region into a DC ? Region can only be selected as clipping region, meta region, or used in PaintRgn directly.

Try: EnumDisplayDevices

As you said, compiler optimization in release mode may have removed the divide-by-zero.

( (GetRValue(cr) >> 3) << 11 ) | ( (GetGValue(cr) >> 2) << 5 ) | (GetBValue(cr) >> 3)

hBmp should be selected into srcMemDC. Destination bitmap missing.

Convert the image to one of the closest DIB format, and then use StretchDIBits to display it. My guess is that each pixel is a 16-bit grayscale level, so the closest DIB format would be 8-bit grayscale image, or a 256-color DIB with a grayscale color table. Setup a BITMAPINFO structure with a 256-color grayscale color table, convert the image array to a 64x64 BYTE array, and then use StretchDIBits to display it.

You can use ExtTextOut and glyph index to display any glyph in a font; Or you can use TextOutW or ExtTextOutW to display UNICODE string without using glyph index. http://www.amazon.com/exec/obidos/ASIN/0130869856

FindResource, LoadResource, and LockResource gives you a pointer to read-only data.

Select bitmap into the memory DC before drawing.

Sounds like a bug in the IDE, edit the .rc file yourself.

Each Win32 process has its own independent address space, of which only the upper part is shared system wide. For example, address 0x10000000 can point to different data in process1 vs. process2. http://www.amazon.com/exec/obidos/ASIN/0130869856

Create a DIB section and a memory DC, select the DIB section into the memory DC, play the metafile into memory DC, now you got a bitmap in the DIB section. http://www.amazon.com/exec/obidos/ASIN/0130869856

DWORD size = GetRgnData(hRgn, 0, NULL); RGNDATA * pData = (RGNDATA *) new BYTE[size]; GetRgnData(hRgn, size, pData); WriteFile(hFile, ,,, pData, size,,,); delete [] (BYTE *) pData;
