[AccessD] Cheecking field exists

Thanks folks
 
One of our medical people wants a highly interactive search screen built for doctors to use. Sets of check boxes etc. Was stuck there for a bit.

Martin:

Here's a snip where I add a field based on the field count of a table. 
I suppose instead of checking the field count you could loop through the
fields collection looking at the field names.

Rocky

Dim wrk As DAO.Workspace
Dim tdf As DAO.TableDef
Dim fld As DAO.Field

Set wrk = DBEngine.Workspaces(0)
Set Db = wrk.OpenDatabase(gstrDatabaseName)
Set tdf = Db.TableDefs("tblPartMaster")

If tdf.Fields.Count = 24 Then
    Set fld = tdf.CreateField("Picture", DB_TEXT, 255)
    fld.Properties("AllowZeroLength") = True
    tdf.Fields.Append fld
End If

Set fld = Nothing
Set tdf = Nothing
Set Db = Nothing
Set wrk = Nothing
