That is for Windows CE only.  "PROP_BUFFER" returns NULL data on
Win32.

An HWND does not store that information.  You cannot retreive the
filename directly from an HWND alone.  What you will have to do
instead is use GetWindowThreadProcessId() to get the process ID of the
HWND, and then loop through all of the running processes on the
machine until you find a matching ID.  Then you will know the
filename.

See the help section:  Retrieving a Window Property
http://msdn2.microsoft.com/en-us/library/Aa929345.aspx

hMemProp = (HGLOBAL) GetProp(hwndSubclass, "PROP_BUFFER"); 
lpFilename = GlobalLock(hMemProp); 
nSize = sprintf(tchBuffer,  "Path to file:  %s", lpFilename); 

I haven't found where the magic strings are listed, but you can enum
them with  EnumPropsEx

Good. I didn't like that "solution" anyway.

You didn't mention which function yields " running processes"

Ah! here it is..
SAMPLE: MODLIST.EXE Shows How to Enumerate Processes and Modules
http://support.microsoft.com/kb/192986

CreateToolhelp32Snapshot()
   Process32First()
   Process32Next()

And on the NT lineage (NT,2000,Xp,Vista) there is EnumProcesses
