What is the best way to do this?

Hi, I want to be able to change the appearence of all the shell controls
during runtime, so if i make a new function like reinitiate_cache() in

gcacheviewxp.cpp:

void reinitiate_cache(){

HBITMAP hbmScrollThumb;
hbmScrollThumb = SHLoadDIBitmap (L"scroll_thumb.bmp");
Gdi::SelectObject_I(g_cacheview.hdcScrollThumb, (HGDIOBJ)hbmScrollThumb);

}

and then call that function from for example the control panel, what is the
best way to make the function global so I can call it from the control panel
application?

Should I make a dll so I can call the function through a dll function call
or is there any simplier way to achieve this?

Regards, Dani

With UI customization you can't change or introduce new APIs you can only
change the behavior of the existing ones.

Thanks,

OK, so if I change the code in for example

void
CacheView_t::
Init(
HINSTANCE hInstance,
bool bLargeUi
){

changed code.....

}


How could I call that particular function from the control panel
application?

You can't call it directly. It's not a WIN32 API exposed to the control
panel. It's an internal GWES implementation not exposed to application.
That's what I mean by you can't add new APIs you can only change the
behavior of existing ones.

Is there no way to expose that function to the WIN32 API?

So how can I force that function to execute then, I don´t want to reboot the
device in between?

If I do a reboot between then I could alter a registry key that tells the
Init function to load different kinds of bitmaps for the controls, but I
don´t want to reboot just to get the Init function in GWES to get executed
again!

Do you have any suggestion how I could solve the problem?

Thanks, Dani

you could invalidate windows or send WM_PAINT messages. You will need to
follow through the code to determine how/when that function is called from
externally exposed APIs.

Ok, thanks will try that!

I found out that

CacheView_t::GWECacheSetSysColors

and

WINAPI SetSysColors

have identical parameters so they must be directly connected.

So I think that if I call SetSysColors, that calls GWECacheSetSysColors and
then modify the GWECacheSetSysColors function to load the control bitmaps
from there it should work!

and then of cource send a WM_PAINT message to all of the windows.

Do you think this is the way to do it?
