Change text in this example

3 posts in this topic

Hello,

I've found a nice example in the helpfile "_WinAPI_DrawThemeTextEx"

It works perfect but I'm trying for the last two days to change the text realtime.

This code is very nice but a bit to difficult for me.

is there anyone who can help me?

This is the code from the "Autoit helpfile"

#include <APIThemeConstants.au3>
#include <FontConstants.au3>
#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
#include <WinAPI.au3>
#include <WinAPIGdi.au3>
#include <WinAPITheme.au3>
#include <WindowsConstants.au3>

If Not _WinAPI_DwmIsCompositionEnabled() Then
    MsgBox(BitOR($MB_ICONERROR, $MB_SYSTEMMODAL), 'Error', 'Require Windows Vista or later with enabled Aero theme.')
    Exit
EndIf
