The parameter "flag = 3 => strip leading and trailing white space" is not documented (Parameters), while is reported in the example

in WinApi.au3 include file in _WinAPI_UpdateLayeredWindow() is missing error checking.

UpdateLayeredWindow API doesn't exists on WIN9x Windows (only WIN 2000 and above) so if you call this UDF function on WIN9x it crashes with this error:

==> Subscript used with non-Array variable.: 
Return SetError($aResult[0] = 0, 0, $aResult[0] <> 0) 
Return SetError($aResult^ ERROR

After DllCall() should be added this:

If @error Then Return SetError(1, 0, 0)

Here is complete testing script with original commented UDF and corrected one:

_WinAPI_UpdateLayeredWindow(0, 0, 0, 0, 0, 0, 0, 0, 0)

;~ Func _WinAPI_UpdateLayeredWindow($hWnd, $hDCDest, $pPTDest, $pSize, $hDCSrce, $pPTSrce, $iRGB, $pBlend, $iFlags)
;~ 	Local $aResult

;~ 	$aResult = DllCall("User32.dll", "int", "UpdateLayeredWindow", "hwnd", $hWnd, "hwnd", $hDCDest, "ptr", $pPTDest, "ptr", $pSize, _
;~ 			"hwnd", $hDCSrce, "ptr", $pPTSrce, "int", $iRGB, "ptr", $pBlend, "int", $iFlags)
;~ 	Return SetError($aResult[0] = 0, 0, $aResult[0] <> 0)
;~ EndFunc   ;==>_WinAPI_UpdateLayeredWindow

Func _WinAPI_UpdateLayeredWindow($hWnd, $hDCDest, $pPTDest, $pSize, $hDCSrce, $pPTSrce, $iRGB, $pBlend, $iFlags)
	Local $aResult

	$aResult = DllCall("User32.dll", "int", "UpdateLayeredWindow", "hwnd", $hWnd, "hwnd", $hDCDest, "ptr", $pPTDest, "ptr", $pSize, _
			"hwnd", $hDCSrce, "ptr", $pPTSrce, "int", $iRGB, "ptr", $pBlend, "int", $iFlags)
	If @error Then Return SetError(1, 0, 0)
	Return SetError($aResult[0] = 0, 0, $aResult[0] <> 0)
EndFunc   ;==>_WinAPI_UpdateLayeredWindow

All tested on AutoIt 3.2.10 on WIN98SE

I would like to request a macro for the script you are currently running in, such as Array.au3 or My_Included_File.au3. This would help me a lot when I am Debugging.

@ScriptName only returns the name of the file executed.

@CurrentScript - Returns the name of where the code is being executed from.
