Window Handle

Two properties allow access to the handle of the Revit main window:

• Autodesk.Revit.UI.UIApplication.MainWindowHandle
• Autodesk.Revit.UI.UIControlledApplication.MainWindowHandle

This handle should be used when displaying modal dialogs and message windows to insure that they are properly parented. Use these properties instead of System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle, which is not a reliable method for retrieving the main window handle.
