Here's the example of auto-complete. This example is for a combobox that
holds a list of fonts available. So I have the data table that is bound to
the combobox for the user's selection, and a collection of entries for the
auto-completion. I would think this would work for a textbox; if it doesn't,
post back and I'll go pull out Brian's book. I'm sure he has an example for
a textbox.

-------------------------------------

//variable checked in the selectedIndexChanged event
//  to suppress the event when the combobox
//  is being loaded
private bool m_loading;

//table of fonts
private DataTable dtFonts;

//collection to use for auto-completion of the font names
private AutoCompleteStringCollection m_Fonts;

private void LoadFontComboBox()
{
   m_Loading = true;
   //Set up datatable to bind to the combobox
   //  so you can use autocomplete.
   dtFonts = new DataTable();
   dtFonts.Columns.Add(new DataColumn("fontName"));

   m_Fonts = new AutoCompleteStringCollection();
   InstalledFontCollection m_allFonts = new InstalledFontCollection();
   foreach (FontFamily oneFamily in m_allFonts.Families)
   {
      if (oneFamily.IsStyleAvailable(FontStyle.Regular))
       {
           dtFonts.Rows.Add(oneFamily.Name);
           m_Fonts.Add(oneFamily.Name);
       }
   }
   FontFamilyComboBox.AutoCompleteCustomSource = m_Fonts;
   FontFamilyComboBox.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
   FontFamilyComboBox.AutoCompleteSource = AutoCompleteSource.CustomSource;

   //databind the combobox
   FontFamilyComboBox.DataSource = dtFonts;
   FontFamilyComboBox.DisplayMember = "fontName";
   FontFamilyComboBox.ValueMember = "fontName";

   m_Loading = false;
}
