Working with complicated controls

Hi there!
There a simple form with a complicated control on it. Let's say, Outlook Bar control, for instance.
The task is to change font for a particular element of the control.
What is the general approach to resolve similar problems using API functions?
Thanks a lot in advance.

Does the control have its own Font property?

Yes, it does but it does not work in runtime.
Besides Font property was implemented to change font for all elements of the control. I need to change font for selected element/s.

You can get the hWnd of the element of the control - each one is a window.

Then you can use SendMessage hWnd, WM_SETFONT

Code:

---

' note the change in red
Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As  _
Long, ByRef wParam As Long, lParam As Any) As Long
Private Const WM_SETFONT = &H30
Call SendMessage hWnd,WM_SETFONT,hFont,True

---

hWnd - window handle
WM_SETFONT - tell the window to change fonts
hFont - Font handle - a LOGFONT structure passed ByRef
True - force a repaint with the new font.

I guess I need to clarify my example.
I can easily get Window handle via hWnd property of Outlook Bar. Then I can also get a set of Window handles of child windows via EnumChildWindows. The question is what then? No one of child windows is accepted SendMessage function. I cannot receive any information about these windows via GetClassInfo or GetClassInfoEx functions. They do not work in this case.
So the task could be stated this way: how to get the Window handle of the right window?
Best regards,
V.
