I am alwayas receiving a 0xc0020001 unknownException when exiting my app. I guess this comes from an improper disposal of the DockingManager manager that is hosted on a custom userControl. I ''ve tried some tricks found in older posts but with no success. Please have a look at the attached sample. Click on of the two menus before exiting the app. to get the erroneous behavior. thanks Clark

Hi Clark, I was able to see the problem and I have included the code to dispose the docking controls explicitly in the menu form closing event. And also I have included the DisposeControls public method in the MyTabPage user control which is used to dispose all the docking controls in the current invoking tab page control. Please take a look at the attached sample which illustrates the above functionality and let me know if this helps you. Thanks for your patience. Regards, Vijay Modified Sample
