>I have been learning the ADOX model to manipulate an exisiting Microsoft Access database. My question concerns Field Size on a text field. Any way to change it programatically?

Try the following:

oCn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\myfolder\db1.mdb;"
oCn.Execute "ALTER TABLE [myTable] ALTER COLUMN [Column3] text(20);", ,adExecuteNoRecords

It's not ADOX but it should work. HTH
