Is there any way to change the background color of a messagebox?

[LarryChen]

Here is what I did,

oldHook = ::SetWindowsHookEx(WH_CALLWNDPROCRET, CallWndRetProc, NULL, ::GetCurrentThreadId());

MessageBox(...);

UnhookWindowsHookEx(oldHook);

Then within the callback function CallWndRetProc, I tried to change the background color of the dialog,

PAINTSTRUCT ps;
HDC hdc = BeginPaint(msg->hwnd, &ps);

::SetBkColor(hdc, RGB(255, 0, 0));

EndPaint(msg->hwnd, &ps);

But it doesn't change the background color of the dialog. I wonder what is the right way to do that? Thanks.
