hello, i will want help too, I attempt run DLLCALL winth GetOpenFileName, but by moment nothing of my attempt result. Mi code is:

$dll = DllOpen("comdlg32.dll")

$str1=" dword lStructSize; hwnd hwndOwner; hwnd hInstance; ptr lpstrFilter;"

EndIf

$result=DllCall($dll,"int", "GetOpenFileName","ptr",DllStructGetPtr($openFN)) :this param is for call de GetOpenFileName function, but de return value is cero, but the significance is that the one error has ocured how the user close de box or any thing for style. But for other side de CommDlgExtendedError report that the funtion has calling sucefully.

$result2=DllCall($dll,"dword", "CommDlgExtendedError","none","") ; this param is for check error en de call of function GetOpenFileName, but at firts glace I get of this function one notice. What the function GetOpenFileName Work Well

MsgBox(0,"el valor de la variable $62 es", $result[0] & @CRLF _

& $result[1] )

MsgBox(0,"el valor es", $result2 )

DllClose($dll)

I show the var content any times for check that the arguments are correct, but yet not work, the function GetOpenFilename always return cero value, but this we say that the function fail. I dont know if is for one error in the ESTRUCT param or is one error in the DLLCALL. Any can help me plis.
