[RESOLVED] group box and radio buttons

[vbforever23]

Hi folks.

I have put some radio buttons into a group box. When I run the program and select a button, a message box pops up with a message about the current button, and then another box pops up with a message about the newly selected button. I understand that this is because CheckedChanged happens twice(for the current button and for the newly selected button).

1. What can I do so that only the change for the newly selected button is recognised? I don't care about the CheckedChanged state for the currently selected button.

2. Besides being a visual container for the radio buttons, does the group box server any other purpose, and should code for the group box be included in my code?

Thanks in advance.

Public Class Form1
    Dim frequency As String
    
    Private Sub rdoYearly_CheckedChanged(sender As System.Object, e As System.EventArgs) Handles rdoYearly.CheckedChanged
        MsgBox("Yearly")
    End Sub

    Private Sub rdoWeekly_CheckedChanged(sender As System.Object, e As System.EventArgs) Handles rdoWeekly.CheckedChanged
        MsgBox("Weekly")
    End Sub

    Private Sub rdoMonthly_CheckedChanged(sender As System.Object, e As System.EventArgs) Handles rdoMonthly.CheckedChanged
        MsgBox("Monthly")
    End Sub

    Private Sub rdoDaily_CheckedChanged(sender As System.Object, e As System.EventArgs) Handles rdoDaily.CheckedChanged
        MsgBox("Daily")
    End Sub
End Class
