Programatically access Search richt text edit box in Outlook

[BeSharp]

Hi there,

I'd like to write a small C# application which sends some text to the Outlook 2007 Search box.

Spy++ reveals that the control has a class of

RichEdit20W

with an empty caption and is part of the overall main window:

class: rctrl_renwnd32
caption: Inbox - Microsoft Outlook

While I managed to get a handle to the main window using the user32.dll GetWindow() method, I cannot get a handle to the rich text box. I tried everything I can imagine so far. The problem might be, that all overloads of FindWindow() and FindWindowEx() seem to expect a String caption but the rich text box has an empty one. Passing in an empty string ("") does not yield any results.

Question:
How can I get a handle to that control, when all I know is the class name?
