My CListBox won't accept the keyboard focus

Hello All,

I am working on implementing a Multiple undo dropdown on my tool bar ---
like developer studios. To do this I create a window that contains a static
text box, and a class derived from CListBox. This window is a child of the
desktop so that it overlaps everything. (If I use a popup, the app gets the
inactive look when the window pops up). 

The problem I am having is that I can't set the keyboard focus to the list
box. m_list.SetFocus() returns null, even though GetFocus() does not.
According to the documentation this means that the m_list window handle is
invalid, but I don't know why. I am making this call from within DoModal,
just before I call RunModalLoop.

Any suggestions as to why I can't give the keyboard focus to my dropdown?

Thanks for any help,
Paul Martinsen.
BTW: I am pretty sure it is correct to make the desktop the owner. MSVC
seems to do that.

Hi,

Try to Set the focus in the parent windows WM_CREATE

		 (or)

Post a WM_USER+?? message to itself in the parent 
window and set the focus in the Handler for the 
user - defined message.

PS: to be really sure that your Listbox is created,
alive and well. use GetSafeHwnd() to check.... HTH.
