a test to know if a handle is a resource handle or a file handle

[TouEnMasm]

The test:

invoke SizeofResource, hInstance,hFile ; hfile = createfile

return 0 on XP but i am not sure it work on any system.
Thanks for testing it,if it don't work , return "BAD TEST..".

Seems there is many class.
To use them there is  need to create a c++ library (PROC C)who call those functions.

If it failed on some machine , i change it.

The value of an Handle of resource seem to be greater than the module handle (hinstance).It's not the case for Hfile handle.
The test is:

mov hFile,eax
.if eax < hInstance
invoke printf,TXT("GOOD TEST hFile isn't a resource Handle",10,0)
.else
invoke printf,TXT("BAD TEST hFile isn't a resource Handle",10,0)
.endif
invoke loadrcdatafile,2000,addr fileini
mov eax,fileini.Hmem
.if eax > hInstance
invoke printf,TXT("GOOD TEST Hres is a resource Handle",10,0)
.else
invoke printf,TXT("BAD TEST Hres is a resource Handle",10,0)
.endif
