owner
text

Return Value

One of the DialogResult values.

You can use the owner parameter to specify a particular object, which implements the IWin32Window interface, that will serve as the dialog box's top-level window and owner. A message box is a modal dialog box, which means no input (keyboard or mouse click) can occur except to objects on the modal form. The program must hide or close a modal form (typically in response to some user action) before input to another form can occur.

By default, the message box displays an OK button. The message box does not contain a caption in the title.
