emails to sort through first.  Thanks!!

Hi Anthony,

I usually use DAO for this:

Usage:
Call CreatePKAutoIncr(CurrentDB, "Table","Field",True)

Private Function CreatePKAutoIncr(objDB As DAO.Database,  _
tdfName As String, fldName As String, PK As Boolean)

Dim tdf As DAO.TableDef
Dim fld As DAO.Field
Dim idx As DAO.Index

    objDB.TableDefs.Refresh
    Set tdf = objDB.TableDefs(tdfName)
    Set fld = tdf.CreateField(fldName, dbLong)
        With fld
          .OrdinalPosition = 0
          .Attributes = dbAutoIncrField
        End With
    tdf.Fields.Append fld

    If PK = True Then
        Set idx = tdf.CreateIndex("PrimaryKey")
        With idx
          .Primary = True
          .Required = True
          .Unique = True
        End With

        Set fld = idx.CreateField(fldName)
        idx.Fields.Append fld
        tdf.Indexes.Append idx
    End If
    RefreshDatabaseWindow

Exit_CreatePKAutoIncr:

On Error Resume Next
    Set idx = Nothing
    Set fld = Nothing
    Set tdf = Nothing
Exit Function

Err_CreatePKAutoIncr:

        MsgBox Err.Description, , "Error in Function mTbl.CreatePKAutoIncr"
        Resume Exit_CreatePKAutoIncr

End Function
