What you can do with that is call EnumProcesses to get all the process id's in the system and then call GetProcessMemoryInfo for each process id. Or if you already have a process id you can just call GetProcessMemoryInfo.

This is in the Process Status Helper library and is available only on WinNT, this won't work on 95/98 to my knowledge.

you could use the GetProcessHeap function to get the handle from the process.. then call HeapSize to determine the size of the process...

Unfortunately GetProcessHeap will only give you a handle to the heap of the calling process. You can't use this to look at the heaps of other processes.
