Hey guys,
So I am trying to use a DLL to install a custom Today Theme into a Windows Mobile 5 Device.

I used the code from this old post:

But this won't work for Windows Mobile 5 anymore. I have a hunch that I need to alter some additional registry, but I have no idea what. Or maybe I need to send out a different kind of broadcast message to inform the OS that the Theme has changed and a new one should be used instead.

When I use the code from the old post, the actual registry value is correctly changed. But the theme doesn't change, even after I reset my unit.

I have also read that very helpful post by Menneisyys

Kudos for taking the time to make such a high quality post!

Can anyone help me out? I have been working on this bloody bug for a week now

So the basic problem is that I need to send out a new message to tell the OS read the new values from the registry. Does anyone know what call I need to make to update registry values?

It seems that the SendMessage(HWND_BROADCAST, WM_WININICHANGE, 0xF2, 0) is not taken in account.

Try to set some dummy BaseHue in registry at the end of your function :

HKEY LOCAL MACHINE\ Software\Microsoft\Color\BaseHue

I have experimented this with my program ThemeGenCE when PDA is connected with ActiveSync. Modifiing Basehue forces Windows Mobile to refresh screen.
You can have a try with ThemeGenCE for direct interaction with PDA screen, only by modifiing BaseHue (fourth tab of main page -WM5-, WM5 button, interact with PDA checked and moving BaseHue on color scale)

I will give that a try when I get back to work monday. But I will add that I did try to edit that BaseHue registry using a registry editor, and it did change the tool bar color but not the today theme.

I will try it in code and see if it works differently.

I still believe there is some special command I need to give to update the theme. I have a theme generator program and it somehow forced the theme to change after it it run. If I could only figure out what that program calls, i will be set!
