                throw new ApplicationException("An error has occured");
            }
            catch (ApplicationException ex)
            {
                // Define a new top-level error message.
                string str = "The action failed.";

                // Add the new top-level message to the handled exception.
                ApplicationException exTop = new ApplicationException(str, ex);
                exTop.Source = this.Text;

                // Show an exception message box with an OK button (the default).
                ExceptionMessageBox box = new ExceptionMessageBox(exTop);
                box.Show(this);
            }

Try
    ' Do something that may generate an exception.
    Throw New ApplicationException("An error has occured")
Catch ex As ApplicationException
    ' Define a new top-level error message.
    Dim str As String = "The action failed."

    ' Add the new top-level message to the handled exception.
    Dim exTop As ApplicationException = New ApplicationException(str, ex)
    exTop.Source = Me.Text

            catch (ApplicationException ex)
            {

                exTop.Data.Add("AdvancedInformation.UserContext", "single user mode");
