  Parent window for the exception message box.

Rückgabewert

Typ: System.Windows.Forms.DialogResult
The DialogResult of the button clicked by the user.

Hinweise

When Buttons is Custom, Show always returns Cancel. Use CustomDialogResult to determine which button the user clicked.

When a nullein NULL-Verweis (Nothing in Visual Basic) value is supplied for Owner, the exception message box appears on the Windows Taskbar. We recommend that you pass the parent window object instead.
