im loading dll on runtime and finding functions with GetProcAddress
how to invoke from eax register ?
im getting error "operand size not specified"
invoke eax,'c:\test.txt',0x40000000 or 0x80000000,0,0,2,7,0
same with
invoke dword eax,'c:\test.txt',0x40000000 or 0x80000000,0,0,2,7,0
seems invoke macro is putting 'dword' in [] with 'eax'[/code]

Use stdcall - invoke is always indirect.
