Question

I am kinda newbie on Visual basic 2010, and wanted to create a chat loader, and i wanted it to read values from a xml table.

This is the code i have used in Vb.

 ChatXml.ReadXmlSchema(My.Application.Info.DirectoryPath & "/../Release/chat.xml")
 ChatXml.ReadXml(My.Application.Info.DirectoryPath & "/../Release/chat.xml")
 ComboBox1.DataSource = ChatXml.Tables
 ComboBox1.DisplayMember = "chat"

And the xml file.

<?xml version="1.0" encoding="utf-8"?>
 <chat>
    <gn>Help</gn>
    <gid>1913106</gid>
    <xc>2336</xc>
    <cn>1500337760</cn>
    <g8>g8</g8>
 </chat>

That i want it to do, is to read the value “gn”, and add it to the ComboBox, i am not sure what is wrong, tried the “Google is your friend” and could not find something that worked.

The error i get is this.

Complex DataBinding accepts as a data source either an IList or an IListSource.

Not sure, but tried to add data to the Tables in DataSet, but seems i can’t get it to work.
Any help?

Your problem is that you are instructing the combo box to show all the rows in the chat table, rather than telling it to show all the gn fields in the chat table. You need to do this:

ComboBox1.DataSource = ChatXml.Tables(0)
ComboBox1.DisplayMember = "gn"
