I normally click a button to initiate a process on the `vsto` add-in. when the process is done, feedback is received is received in form of a `MessageBox`. now here is the issue. If I remain inside Word while the process completes, the `MessageBox` doesn't show as an extra task/window in the task bar. If I initiate the process, then move to a different app or to a different document window, the message box shows up in the task bar and stays on its own so that i can still continue working on even the active document where the process was initiated without having the UI thread blocked which is supposed to be the usual case. How do I make it always belonging to the Word app even if it is not the active app?

Always set the Word window as the owner of the MessageBox.
In C# for a VSTO add-in, use:
var wordHandle = new IntPtr(Globals.ThisAddIn.Application.Hwnd);
MessageBox.Show(new WindowWrapper(wordHandle), "Process complete!");
This ensures the MessageBox is modal to Word (always belonging to it) and never appears as a separate taskbar item.
