End If
If (createAttached(Me!txttblname, Me!txtdbname, Me!txttblname)) Then
MsgBox ("Table is created")
End If
End Sub
Function createAttached(strTable As String, strPath As String, strBaseTable As String) As Boolean
On Error GoTo CreateAttachedError
Dim tdf As TableDef, strConnect As String, fRetval As Boolean, myDB As Database
DoCmd.SetWarnings False
Set myDB = CurrentDb
Set tdf = myDB.CreateTableDef(strTable)
With tdf
.Connect = ";DATABASE=" & strPath
.SourceTableName = strBaseTable
End With
myDB.TableDefs.Append tdf
fRetval = True
DoCmd.SetWarnings True
createAttached = fRetval
Exit Function
If Err = 3110 Then
Resume CreateAttachedExit
If Err = 3011 Then
