Want to call .net func _Help::ShowHelpIndex.Here is the link in msdn:https://msdn.microsoft.com/en-us//library/system.windows.forms.help.showhelpindex.

I wrote the script below:

$dll = DllOpen("C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Windows.Forms.dll")
$result = DllCall($dll, "none", "ShowHelpIndex","HWND", 0,"wstr","D:\Program Files\AutoIt3\AutoIt3CHS.chm")
_check_result()
DllClose($dll)

Func _check_result()
        If @error Then
                ConsoleWrite(">--|error:=" & @error & "|--<")
                ConsoleWrite(@LF)
        Else        
                ConsoleWrite(">--|$result:=" & $result[0] & "|--<")
                ConsoleWrite(@LF)
        EndIf        
EndFunc

Can someone give some advices?

tks in advance

Failure: sets the @error flag to non-zero. 
@error: 1 = unable to use the DLL file,
2 = unknown "return type",
3 = "function" not found in the DLL file,
4 = bad number of parameters,
5 = bad parameter.
