Hello, I am writing a Addin for SW2003 with Visual C++ 7. I have created a new FeatureManager design tree view with the following methods ModelDoc2->ICreateFeatureMgrView3 ( bitmap, toolTip, whichPane, &retval ) retval->GetFeatMgrViewWnd(&handle) The command creates a new (empty) view, but I don´t know what to do with the returned CWnd handle (long) retval. I would like to add some controls and other stuff, is this possible at all? I´m very confused. Can someone give me a hint? Regards, Andreas
