Hi, I have a confirmation message box for the user in one of my apps. Below is the code for that,

MessageBoxResult res= System.Windows.MessageBox.Show("Could not find the folder, so the D:  Drive will be opened instead.");
                if (res == MessageBoxResult.OK)
                {
                    MessageBox.Show("OK");
                }
              else
                {
               MessageBox.Show("Do Nothing"); 
                }

Now, when the user clicks on the OK button, I want certain code to execute but when they click on the red cross at the upper right corner, I just want the messagebox to close without doing anything. In my case I get 'OK' displayed even when I click on the red cross icon at the upper right corner. Is there a way I can have 'Do Nothing' displayed when I click on the cross. I not want to add any more buttons.
