Question

Okay this is what I have so far. I have a form that needs to load a file externally and populate the combobox. I can get that part if I use a button, but I don’t want to use a button. I want it to populate when the form loads for the first time. The below code does not accomplish this, it doesn’t even try to load it. I put break points in this code but it never breaks. I am thinking that the combobox isn’t loaded yet and the program doesn’t try.

Any help would be nice.

Private Sub mortCalMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    'sets listview values
    mortBox.SelectedIndex = 0

    Dim rdr As StreamReader = File.OpenText("mortgageTypes.txt")

    While Not rdr.EndOfStream
        Dim line As String = rdr.ReadLine()
        mortBox.Items.Add(line)
    End While

    rdr.Close()
End Sub

Comment out this line:

'mortBox.SelectedIndex = 0

You can’t set the index on an empty list.
