Hello everyone.

How to specify the encoding when i pass a string using invoke macro?

For example:

Code:

invoke MessageBox,HWND_DESKTOP,"Message","Caption",MB_OK

How to specify explicitly the strings encoding? If i use w-extended header it always uses UNICODE, if a - ANSI. How to pass an UNICODE string using a - header, or ANSI using w header (for example to using GetProcAddress)?

alternatively, you can declare

Code:

 IMPORT64.INC [62]:
            db string,0
  load test byte from ($ - 2)
            rb RVA $ and 1
   if test = "W"
    define label#.TCHAR du
    define label#.sizeof.TCHAR 2
  else
    define label#.TCHAR db
    define label#.sizeof.TCHAR 1
  end if

in the import macro, and check for the corresponding value in the invoke macro

Code:

PROC64.INC [50]:
  if defined proc#.sizeof.TCHAR & defined proc#.TCHAR
           align proc#.sizeof.TCHAR
           ..string proc#.TCHAR definition@param,0
  else
           align sizeof.TCHAR
           ..string TCHAR definition@param,0
  end if

Code:

 PROC64.INC [42]:
  if defined proc#.sizeof.TCHAR & defined proc#.TCHAR
           align proc#.sizeof.TCHAR
           ..string proc#.TCHAR definition@param,0
  else
           align sizeof.TCHAR
           ..string TCHAR definition@param,0
  end if

well, etc. I have already rewritten my own for a long time, so I don't have such a problem

invoke MessageBoxW,...
invoke MessageBoxA,...

Use the full name of api, not shorter one.
