Examples

This example is for a document-level customization.

private void PromptUnprotectWorksheet()
{
    if (this.ProtectContents)
    {
        if (DialogResult.Yes == MessageBox.Show("The worksheet is protected. " +
            "Unprotect the worksheet?", "Example",
            MessageBoxButtons.YesNo))
        {
            this.Unprotect();
        }
    }
}

Private Sub PromptUnprotectWorksheet()
    If Me.ProtectContents Then
        If DialogResult.Yes = MessageBox.Show("The worksheet is protected. " & _
            "Unprotect the worksheet?", "Example", MessageBoxButtons.YesNo) Then
            Me.Unprotect()
        End If
    End If
End Sub
