Hi, currently I'm reading the custom properties from  a file and putting them in a ListBox. Propnames are the names of the properties and Propval are the values of these properties. I'm using VB.NET with the Document Manager API.

    Public Sub ReadWriteProps()

            propNames = dmDoc.GetCustomPropertyNames()

        If Not propNames Is Nothing Then

            clb_Properties.Items.Clear()

            For Each propName As String In propNames

                propVal = dmDoc.GetCustomProperty(propName, Nothing)

                clb_Properties.Items.Add(propName & ": " & propVal)

            Next

        End If

    End Sub

I have put a textbox beneath this and would like 2 things.

I'd like to display the value of the selected item in the listbox. Currently I use this code, but it gives me both the value and the name.

    Private Sub clb_Properties_SelectedIndexChanged(sender As Object, e As EventArgs) Handles clb_Properties.SelectedIndexChanged

        txt_PropertyEdit.Text = propVal(clb_Properties.SelectedItem)

    End Sub

Secondly, I'd like to click a button and then this would trigger the replacement of the value in the listbox of the selected item with the given value in the textbox.

    Private Sub btn_Edit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btn_Edit.Click

        propVal(clb_Properties.SelectedIndex) = txt_PropertyEdit.Text

    End Sub

This code however, gives me an error. I've also tried the 'SelectedItem' function. Does someone know how I fix this?

Greetings!
