Public Overrides Function Read() As Boolean

public override bool Read()

Returns true if there are more rows. Otherwise, it returns false.

The default position of the SADataReader is prior to the first record. Therefore, you must call Read to begin accessing any data.

The following code fills a listbox with the values in a single column of results.

while( reader.Read() ) {
    listResults.Items.Add( reader.GetValue( 0 ).ToString() );
}
listResults.EndUpdate();
reader.Close();
