IWin32Window in WPF

Question

I have an excel AddIn which exposes IWin32Window as it's main UI. I want to show a WPF window that uses this as it's parent.

How do I go about doing that ?

You can use WindowInteropHelper to parent the WPF window appropriately:

var helper = new WindowInteropHelper(theWpfWindow);
helper.Owner = win32Window.Handle;

theWpfWindow.Show(); // This is now parented appropriately

I have this: System.Windows.Forms.IWin32Window (note, it is NOT namespace). MainHostWindow host = new MainHostWindow(); var helper = new WindowInteropHelper(host); helper.Owner = this._mainWindow.Handle; host.Owner is NULL

@Pacman: host.Owner will stay null - you just set the interop helper as I showed, and it should parent it appropriately. If you want it modal, use ShowDialog()...

What is I want to make the Owner Window Disabled: host.Owner.IsEnabled = false ?

@Pacman: You're trying to disable Excel's main window? You won't be able to do that from an extension - better to just use ShowDialog() to open your window modally, which will prevent the user from interacting with the host until you close your window.

I think you need to use a WindowInteropHelper, like shown here: IWin32Window Owner For WPF Window
