<!-- REMOTE_HOST: 194.201.13.162; REMOTE_ADDR: 194.201.13.162-->
<P>After looking for a file/directory listing Tree control I found the CDriveView control available from MSJ. This is designed to work within the view/document architecture as a view. Great!!
<P>However, I wanted this control inside a dialog box, so I have reworked the code slightly to allow this to just derive from a CTreeCtrl.
<P>Ok, everything works okay, but I can't get the Treeview notification messages from the derived treeview control (which is in my dialog box).
<P>These are the two entries in the dervied control's message map, which *NEVER* get called:
<P>ON_CONTROL_REFLECT (TVN_ITEMEXPANDING, OnItemExpanding)    ON_CONTROL_REFLECT (TVN_SELCHANGED, OnSelChanged)
<P>Does anyone have any ideas why these messages aren't hitting my control?
<P>In contrast if I put in the following messages:
<P>ON_WM_LBUTTONDOWN()
<BR>ON_WM_LBUTTONDBLCLK()
<P>these both get called.
<P>I've just spent the last few hours trying to figure it out what's going wrong, but just can't!!
<P>Help!
<P>Richard.
