I have a little problem that nearly drives me xx! I've five Checkboxes and when I check the fifth I want the others to be unchecked and number five stay checked.
In runtime I got stuck with owerflow when it lies in "CheckBox5_CheckedChanged" Method and in other it wont just work guess it pretty simple right?

Code:
    Private Sub CheckBox5_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox5.Click
        Dim Check As Control

        If CheckBox5.Checked = True Then 
            CheckBox5.Checked = False
            Exit Sub
        Else
            For Each Check In Me.GroupBox1.Controls
                If TypeOf Check Is CheckBox Then
                    CType(Check, CheckBox).Checked = False
                End If
            Next

            CheckBox5.Checked = True
        End If

    End Sub
