Apply Windows Theme

i did a little research on msdn and google, but couldn't get any helpful information. what i'm trying to do is to install and apply a theme for windows xp (i.e. $WINDIR\Resources\Themes\Windows Classic.theme).

when you do it over the registry, the theme won't be installed until next reboot. i'm not sure if one can install it using anything related to rundll32.exe shell32.dll,Control_RunDLL desk.cpl without pressing an extra button (OK or Apply) to apply it.

there might be a system-call, but i couldn't find anything (this might be a hint).

can anyone help me?

i know this has to be possible style xp does it and ive seen a self extracting copy of windows 3000 theme somewhere at one point that did it too.

But I think easy to use:

ExecShell "open" "$WINDIR\Resources\Themes\Windows Classic.theme"

Instructor,

that just brings up the dialog to change the theme it doesnt actually apply it

I know. See link above.

is it SetWindowTheme to use or do you suggest using ExecShell and CloseThemeData?

Yathosho, you can use API or ExecShell.

I tried to write a code, but have faced a problem with API - $1 is NULL:

System::Call 'user32::GetDesktopWindow()i .r0'

System::Call 'uxtheme::OpenThemeData(i r0, t L"StartPanel")i .r1'

Try this:

Name "ChangeStyleXP"

OutFile "ChangeStyleXP.exe"



!include "FileFunc.nsh"

!insertmacro GetFileName



!define BM_CLICK 0x00F5

!define WM_CLOSE 0x0010

	StrCpy $3 0



	wait:

	${GetFileName} '$2' $2

	StrCmp $2 'comctl32.dll' 0 wait



	HideWindow

	GetDlgItem $2 $1 1

	SendMessage $2 ${BM_CLICK} 0 0

	MessageBox MB_OK "Success" IDOK quit



	error:

	quit:
