If I understood you correctly, you already have the information loaded into the combobox and listbox.

To make use of what is selected in the combobox, either use ComboBox1.SelectedValue or ComboBox1.Text in the SQL query. To use what is selected in the listbox, use the listbox's .SelectedIndex, SelectedText, .SelectedValue, .Text, or whichever you need.

After you have deleted the item from the database, clear the databinding of the list box using ListBox1.DataBindings.Clear(), and set it again like you did originally, or something like this:

Me.ListBox1.DataBindings.Add(New Binding("Text", DataSet_Of_Answers, "TableName.ColumnName")
