pass through message map

I have a tree control which I put a message handler on edit, copy, paste,
and delete keys.  When the in place edit control activates while editing a
tree item.. the tree control gets the edit,copy,paste, and delete message
first and never gives it to the edit control.

Q: Is there a way to pass through the message dynamically?

Sincerely,

Roger,
This is probably not the preferred method:
I've emulated the little popup windows that show the entire text of a tree item
if the TreeCtrl window is so small it cuts it off. (Like the tree views in VC 4).

I need to get mouse down messages, but I also need to pass them to the
tree control so it can select the item, expand it, etc.

As you can see, I pack the lparam, take the wparam and call SendMessage.
I suppose that Post Message is less draconian, but I wanted an immediate reponse.

void CTreePopupWnd::OnLButtonDblClk(UINT nFlags, CPoint point) 
{
	DWORD lparam;
	ClientToScreen(&point);
	m_pTree->ScreenToClient(&point);
	lparam = point.y;				// pack point into an lparam
	lparam = lparam << 16;
	lparam = lparam + point.x;		// wparm was the flags in this case.
OTHER STUFF....
	m_pTree->SendMessage(WM_LBUTTONDBLCLK,nFlags,(long) lparam);
OTHER STUFF
}

Hope this helps,
Jim Leavitt
