DialogResult from a MessageBox.Show

How do i use the DialogResult (or something similar) from a MessageBox.Show that has a yes/no option on it?  I want to do one thing if the user selects the yes and another thing if no... i'm sure you get the picture.

i tried the following in my    "Private Sub CheckOutMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckOutMenuItem.Click"
 
MessageBox.Show(messagestring, "Check Out", MessageBoxButtons.YesNo, MessageBoxIcon.Hand)


If optionSelected = DialogResult.Yes Then
            totalSales.salesNumberInteger(1) += TotalCost
            'totalSales.salesNumberInteger(0) = 0
        ElseIf optionSelected = DialogResult.No Then
            clearTransaction()
End If

but when i test it and select either yes or no, i don't get any results... it seems like VB.NET transfer control/focus to something else and my "IF" statement isn't executed.  is there another object that should be used with MessageBox.Show?

thanks

Hi 03xc600,

You need to store the result:
optionSelected = MessageBox.Show(messagestring, "Check Out", MessageBoxButtons.YesNo, MessageBoxIcon.Hand)


Cheers!

the best way to implement this is:
If MessageBox.Show(messagestring, "Check Out", MessageBoxButtons.YesNo) = DialogResult.Yes Then
            totalSales.salesNumberInteger(1) += TotalCost
            'totalSales.salesNumberInteger(0) = 0
        ElseIf optionSelected = DialogResult.No Then
            clearTransaction()
End If

gangwisch,

Your ElseIf does not make sense. No optionSelected is initialized.

Hello,

The REAL best way as I see it is this :

        Dim optionSelected As DialogResult
        optionSelected = MessageBox.Show(messagestring, "Check Out", MessageBoxButtons.YesNo)
        If optionSelected = Windows.Forms.DialogResult.Yes Then
            totalSales.salesNumberInteger(1) += TotalCost
            'totalSales.salesNumberInteger(0) = 0
        ElseIf optionSelected = Windows.Forms.DialogResult.No Then
            clearTransaction()
        End If

Hello 03xc600;

This is how I would do it. I would also set the MessageBox default selected button. In the sample code below the No button in the MessageBox is selected button. If you want to make the Yes the default button then change this, MessageBoxDefaultButton.Button2 to MessageBoxDefaultButton.Button1.

            Dim messagestring As String = "Message to be displayed"
            Dim optionSelected As DialogResult
            optionSelected = MessageBox.Show(messagestring, "Check Out", _
                MessageBoxButtons.YesNo, MessageBoxIcon.Hand, _
                MessageBoxDefaultButton.Button2)
            If optionSelected = DialogResult.Yes Then
                totalSales.salesNumberInteger(1) += TotalCost
               'totalSales.salesNumberInteger(0) = 0
            Else
                clearTransaction()
            End If
