When we moved to CodeJock, we seemed to have lost the capability to provide custom tooltips for items in a tree control. With MFC/Windows I can see that our property page's OnNotify function is called when the tooltip timer trips. The call stack is pretty deep but the result is that the MFC/Windows tooltip system detects the mouse is over the tree control and notifies our property page that contains the tree control using the

TVN_GETINFOTIP

notification message. We return the text at that time. With CJ, the notification is not made. We do get a

TTN_NEEDTEXT

notification on the page as we move over the tree control but the call has no data indicating which item text is being requested for. We ignore the need text call (return zero) and the tip that is retrieved is the text for the item and not the info tip we serve up when we were not using codejock.

What do I need to set so that the CJ tooltip will send the TVN_GETINFOTIP message to get the tip text we want to show?

Where is the handle to the item that text is being request for stored when the TTN_NEEDTEXT notification is made?
