Are you enabling visualstyles in the application?

Try commenting out the line where you do if you are...

I've narrowed the issue down: My app contains Syncfusion Menu bars, if I exit the app via the Syncfusion menu-bar File->exit the app shut's down correctly. If I close the app via the 'X' button in the top-right frame I recieve the exception. However I don't know of any workarounds or fixes(aside from buying CodeJock's commandbars and redesigning all my existing Syncfusion menus).

I'm using the dockingpane ActiveX control in a C# .NET app. My main form is an MDIContainer so in order to create panes I have to include the following code:

foreach (Control ctrl in this.Controls)

{

if (ctrl is MdiClient)

{

DockingPaneManager.SetMDIClient(ctrl.Handle.ToInt32());

}

}

Does anyone know what this code does? And why I receive "NullReferenceException: Object reference not set to an instance of an object" at shutdown when I include it?

I'm using the new dockingpane activeX control version 9.7. Any help/ideas is appreciated!
