Hi, i need yor help please: I want to handle XTP_DPN_PANEMENUCLICK. But when the lParam in this case doesn't point to a valid CXTPDockingPane. What is wrong or how can i get the pane who sends the message? LRESULT CMainFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam) { CXTPDockingPane* pPane = (CXTPDockingPane*)lParam; switch ((int)wParam) { case XTP_DPN_SHOWWINDOW: // here pPane is valid  break; case XTP_DPN_PANEMENUCLICK: // here pPane is invalid  break; } } |

because lParam is XTP_DOCKINGPANE_CLICK pointer. XTP_DOCKINGPANE_CLICK* pClick = (XTP_DOCKINGPANE_CLICK*)lParam; lParam depends on wParam value. move CXTPDockingPane* pPane = (CXTPDockingPane*)lParam; to scope of case XTP_DPN_SHOWWINDOW. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

Yes, sorry was not documented :( Use it as: XTP_DOCKINGPANE_CLICK* pClick = (XTP_DOCKINGPANE_CLICK*)lParam; CXTPDockingPane* pPane = pClick->pPane.
ps. structure declaration struct XTP_DOCKINGPANE_CLICK ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |
