• Put an ADO Data Control on form, and set the properties as follows:
Property Value
Name adoBiblio
DataSourceName Biblio
SQL select * from authors
• Now put three text boxes on the form, and set their Name, DataSource, and DataField
properties as follows:
Name DataSource DataField
txtAuthor adoBiblio Author
txtAuID adoBiblio Au_ID
txtYearBorn adoBiblio Year Born
• Save and run the program. Notice how it works just like the other data control.
• Now change the SQL property of the data control to select * from authors order by author
and run the program again. Notice the difference.
• Change the SQL property back to what it was and add three command buttons to the form,
and set their Name and Caption properties as follows:
Name Caption
cmdNameOrder Order by Name
cmdYearOrder Order by Year
cmdIDOrder Order by ID
• Put the following code in the cmdNameOrder_Click event: adoBiblio.SQL = “select * from
authors order by author” adoBiblio.Refresh
• Put the following code in the cmdYearOrder_Click event: adoBiblio.SQL = “select * from
authors order by [year born]” adoBiblio.Refresh
• Put the following code in the cmdIDOrder_Click event: adoBiblio.SQL = “select * from
authors order by au_id” adoBiblio.Refresh
• Save and run the program and see what happens when we click the buttons.
