I try to allocate approx. 50MB of memory for a DIB:
hDIB= GlobalAlloc(GHND,dw /*approx 50MB*/);
It fails. But Windows task manager told me that more than 500MB available.
The OS is win xp.
Why??? What is the problem?
This needs to allocate a contiguous block of 50MB. This may not be available, though many smaller blocks may be available that together make up more than 500MB.
Maybe you could try preallocating the large block of memory early in your program. Or you could try enabling the low-fragmentation heap if you are running on XP.
