Hi,

Try this code:

Dim AConn As New ADOdb.Connection
Dim ACat As New ADOX.Catalog
Dim ATbl As ADOX.Table
Dim ACol As ADOX.Column
'
AConn.Open("Provider='Microsoft.Jet.OLEDB.4.0';" _
    & "Data Source= C:\MyDB.mdb;")
ACat = New ADOX.Catalog 
ACat.ActiveConnection = AConn
ATbl = ACat.Tables("MyTable")
ACol = ATbl.Columns.Item("MyColName")
ACol.Properties("Jet OLEDB:Allow Zero Length").Value = True
ACat = Nothing

hey

thanx for the reply.

am getting error as invalid use of property and the error is in
ACat = New ADOX.Catalog

i have set all the properties of adox and catalog control.

can u tell me how to rectify this error

thanx a lot

its working fine

u gave the code for changing the particular column of a table and is there any way to change the properties of the entire table i.e. allow zero length should be set false to all the columns in a table.

Hi,

Just Loop through all the Available columns and set the property..

For Each ACol In ATbl.Columns
    ACol.Properties("Jet OLEDB:Allow Zero Length").Value = False
Next

Veena
