Question : OnChange Event (Apply Button) VB.NET

(This is VB.NET)

I have a form with a checkbox (chkbxBackup).  When the checkbox is changed I want to turn on the Apply Button (btnApply).

I have read many posts but do not understand how to write an OnChange Event.  Is it a Function or a Sub? I have seen it different ways.

If I have mutiple checkboxes (I.e. chkbxBackup and chkbxDir) do I have to write 2 OnChange Events?

Any help would be appreciated.

Thanks

Answer : OnChange Event (Apply Button) VB.NET

I think u want something like
Private Sub chkbxBackup_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chkbxBackup.CheckedChanged
if chkbxbackup.checked = true then
btnapply.enabled = true
end if
End Sub

all u have to do is double click on the checkbox u are wanting to work with and then up in the right hand corner below the start button u will see the word checkedchanged, it looks like a drop down box. then select what feature u want and it will put the sub in ur program automatically.

if this wasn't what u wanted I am sorry...
