_WinAPI_SetWindowTheme() - remove limits

Description

Trying to change a color on a checkbox control I needed to remove the theme and found the limitation on the implementation of the wrapper.
The request is to remove the "string or null, only" from the func., as zero is the value that is needed in this case.

#include <WinAPITheme.au3>
Test()
Func Test()
	GUICreate(@ScriptName)

	GUICtrlCreateCheckbox("one", 10, 10, 200)

	GUICtrlCreateCheckbox("two", 10, 30, 200)
	GUICtrlSetColor(-1, 0xFF00FF)

	GUICtrlCreateCheckbox("three", 10, 50, 200)
	_WinAPI_SetWindowTheme(GUICtrlGetHandle(-1)) ;, 0, 0)
	GUICtrlSetColor(-1, 0xFF00FF)

	GUICtrlCreateCheckbox("Four", 10, 70, 200)
	_WinAPI_SetWindowTheme_mod(GUICtrlGetHandle(-1)) ;, 0, 0)
	GUICtrlSetColor(-1, 0xFF00FF)

	GUISetState()
	While GUIGetMsg() <> -3
	WEnd
	GUIDelete()
EndFunc

Func _WinAPI_SetWindowTheme_mod($hWnd, $sName = Default, $sList = Default) ; #include <WinAPITheme.au3>
;~ 	If Not IsString($sName) Then $sName = Null ; <-- this limits what can get done with it.
;~ 	If Not IsString($sList) Then $sList = Null ; also, don't ask me why "Default" works !, I was going to use 0

	Local $sResult = DllCall('UxTheme.dll', 'long', 'SetWindowTheme', 'hwnd', $hWnd, 'wstr', $sName, 'wstr', $sList)
	If @error Then Return SetError(@error, @extended, 0)
	If $sResult[0] Then Return SetError(10, $sResult[0], 0)
	Return 1
EndFunc   ;==>_WinAPI_SetWindowTheme

in 3.3.14.5 it was:

Func _WinAPI_SetWindowTheme($hWnd, $sName = Default, $sList = Default)
	Local $sTypeOfName = 'wstr', $sTypeOfList = 'wstr'
	If Not IsString($sName) Then
		$sTypeOfName = 'ptr'
		$sName = 0
	EndIf
	If Not IsString($sList) Then
		$sTypeOfList = 'ptr'
		$sList = 0
	EndIf

	Local $aRet = DllCall('uxtheme.dll', 'long', 'SetWindowTheme', 'hwnd', $hWnd, $sTypeOfName, $sName, $sTypeOfList, $sList)
	If @error Then Return SetError(@error, @extended, 0)
	If $aRet[0] Then Return SetError(10, $aRet[0], 0)

	Return 1
EndFunc   ;==>_WinAPI_SetWindowTheme

maybe that's better than removing the "If Not IsString($sName) Then $sName = Null" ?

comment:2 Changed 3 months ago by argumentum <argumentum@…>

ok, close this and pardon my ignorance.
Calling $name and $list as an empty string is what I should have done.

anyone reading this in the future, here's an extended/"free style" function:

; these defaults are the most common use when calling SetWindowTheme
; to remove a theme, use name and list with "" ( empty string, do not use 0 as it is not an expected 'wstr' )
Func _WinAPI_SetWindowThemeEx($hWnd, $sName = 'Explorer', $sList = Null, $sTypeOfName = 'wstr', $sTypeOfList = 'wstr')
	Local $sTypeOfName = 'wstr', $sTypeOfList = 'wstr' ; a 'ptr' can be passed too
	Local $aRet = DllCall('uxtheme.dll', 'long', 'SetWindowTheme', 'hwnd', $hWnd, $sTypeOfName, $sName, $sTypeOfList, $sList)
	If @error Then Return SetError(@error, @extended, 0)
	If $aRet[0] Then Return SetError(10, $aRet[0], 0)
	Return 1
EndFunc   ;==>_WinAPI_SetWindowThemeEx

This would work for ... no clue, but is not a bad idea either:

Func _WinAPI_SetWindowTheme($hWnd, $sName = Default, $sList = Default) ; #include <WinAPITheme.au3>
	If Not IsString($sName) Then $sName = Null
	If Not IsString($sList) Then $sList = Null
	Local $sResult = _WinAPI_SetWindowThemeEx($hWnd, $sName, $sList)
	Return SetError(@error, @extended, $sResult)
EndFunc   ;==>_WinAPI_SetWindowTheme

Func _WinAPI_SetWindowThemeEx($hWnd, $sName = 'Explorer', $sList = Null, $sTypeOfName = 'wstr', $sTypeOfList = 'wstr')
	Local $sTypeOfName = 'wstr', $sTypeOfList = 'wstr' ; a 'ptr' can be passed too
	Local $aRet = DllCall('uxtheme.dll', 'long', 'SetWindowTheme', 'hwnd', $hWnd, $sTypeOfName, $sName, $sTypeOfList, $sList)
	If @error Then Return SetError(@error, @extended, 0)
	If $aRet[0] Then Return SetError(10, $aRet[0], 0)
	Return 1
EndFunc   ;==>_WinAPI_SetWindowThemeEx

I don't knowif it is so useful to extend this function as coloring checkbox can be done with the current implementation

#include <GUIConstantsEx.au3>
#include <WinAPITheme.au3>

I went overboard. You are right.
Ok, this modification will take 0 as it did in prior versions.
So it returns the expectation that ",0,0)" would do, without having to "'ptr',0" each field.

#include <GUIConstantsEx.au3>
#include <WinAPITheme.au3>

Func _WinAPI_SetWindowTheme_TakesZero($hWnd, $sName = Default, $sList = Default)
	If Not IsString($sName) Then $sName = ($sName = 0 ? "" : Null)
	If Not IsString($sList) Then $sList = ($sName = 0 ? "" : Null)
	Local $sResult = DllCall('uxtheme.dll', 'long', 'SetWindowTheme', 'hwnd', $hWnd, 'wstr', $sName, 'wstr', $sList)
	If @error Then Return SetError(@error, @extended, 0)
	If $sResult[0] Then Return SetError(10, $sResult[0], 0)
	Return 1

Hi,
there is no bug as 0, 0 will use Null in the current implementation
you must us "", "" if if you want to siable as stated in the doc
