[RESOLVED] Handling dialog box buttons

I have code that pops up a dialog box and waits for either the OK or Cancel button to be clicked. I am trying to figure out how to get and use the repsonse from dialog box. If the user clicks OK, I want the rest of the code to execute normally (it already does this by default). If the user clicks Cancel, I want to skip the rest of the code. I was assuming OK would return TRUE and Cancel would return FALSE, but that apparently is not correct. How do I figure out whether OK or Cancel was clicked?

Code:

---

        If Not MapCheck() = "" Then
            DiaError.TextBoxErr.Text = MapCheck()
            If Not DiaError.ShowDialog() Then  'show dialog box and evaluate output
                GoTo breakme 'if Cancel is clicked
            End If
        End If

        ' Rest of code

---

Instead of:

Code:

---

    If Not DiaError.ShowDialog() Then  'show dialog box and evaluate output
                GoTo breakme 'if Cancel is clicked
            End If

---

use this instead:

Code:

---

Select Case DiaError.ShowDialog()  'test the dialogresult
    Case OK 'edit this for the proper variable

    Case Cancel 'edit this for the proper variable

End Select

Here's what I did to confirm clearing all nodes in a TreeView...

vb.net Code:

Dim ConfirmClear As DialogResult
ConfirmClear = MessageBox.Show("Are you sure that you wish to clear all events?", "Confirm Clear Play Sequence", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2)
 
If ConfirmClear = DialogResult.Yes Then
    tvwPlaySequence.Nodes.Clear()
End If

Adapt for your situation.

Thanks. I used Campion's recommendation.
