I got this piece of line that i can't find why it gets a error:

Code:

invoke EnableDlgItem, [hWnd], IDC_NAME, TRUE

proc32.inc [20] invoke [6]:
call [proc] }
error: operand size not specified.

It's not defined as an API (in the import tables). Call it with stdcall instead.

Code:

stdcall EnableDlgItem, [hWnd], IDC_NAME, TRUE

Should work as ManOfSteel says provided you have a proc (or at least a label) with "EnableDlgItem" name.

The macro will do this:

Code:

push TRUE
push IDC_NAME
push [hWnd]
call EnableDlgItem ; Here invoke does call [EnableDlgItem]

[edit]Removed "dword" from "call dword [EnableDlgItem]" since the invoke macro uses "call [EnableDlgItem]" (so type is determined from the label)[/edit]
