Having trouble with temp table

Hi all,

I have the following code but every time I get to the line marked with
*, I get a Type Mismatch error.

Private Sub Command9_Click()

On Error GoTo Err_Command9_Click

' This subroutine illustrates how to use a temporary MDB in your app.
' If the temporary MDB is present then delete it.
' The name of the temporary MDB created is the same as the current
Front End (FE) name with
' " temp" added to the end of the name.
' Create the temporary MDB.
' Create the temporary table(s) required in the temporary MDB.
' Link to those tables within your current FE
' Do whatever you want
' Unlink the tables'
' Delete the temporary MDB

' While this code is copyright 2000 by Tony Toews it's all code strung
together from the online help so do

Dim tdfNew As TableDef, RS As Recordset
Dim wrkDefault As Workspace
Dim dbsTemp As Database, strTempDatabase As String
Dim strTableName As String

' Get default Workspace.
Set wrkDefault = DBEngine.Workspaces(0)
strTempDatabase = Left$(CurrentDb.Name, Len(CurrentDb.Name) - 4) &
" temp.mdb"

' Make sure there isn't already a file with the name of
' the new database.

If Dir(strTempDatabase) <> "" Then Kill strTempDatabase

'Create a new temp database
Set dbsTemp = wrkDefault.CreateDatabase(strTempDatabase,
dbLangGeneral)

strTableName = "temp Import TNA Results"

'strBracketedTableName = "[" & strTableName & "]"

' Delete the link to the temp table if it exists
If TableExists(strTableName) Then
CurrentDb.TableDefs.Delete strTableName
End If

' Create the temp table
Set tdfNew = dbsTemp.CreateTableDef(strTableName)
With tdfNew
.Fields.Append .CreateField("NAME", dbText)
.Fields.Append .CreateField("USER ID:", dbText)
.Fields.Append .CreateField("JOB TITLE", dbText)

.Fields.Append .CreateField("IMPORT DATE", dbDate)
dbsTemp.TableDefs.Append tdfNew
End With


dbsTemp.TableDefs.Refresh

Dim tdfLinked As TableDef

' Link to the Import tables in the temp MDB
Set tdfLinked = CurrentDb.CreateTableDef(strTableName)
tdfLinked.Connect = ";DATABASE=" & strTempDatabase
tdfLinked.SourceTableName = strTableName
CurrentDb.TableDefs.Append tdfLinked

CurrentDb.TableDefs.Refresh

RefreshDatabaseWindow

* Set RS = CurrentDb.OpenRecordset(strTableName, dbOpenDynaset,
dbAppendOnly) - This is the line

RS.Close
dbsTemp.Close

CurrentDb.TableDefs.Refresh

Set RS = Nothing
Set dbsTemp = Nothing

' Unlink the tables
CurrentDb.TableDefs.Delete strTableName

' Delete the temp mdb
strTempDatabase = Left$(CurrentDb.Name, Len(CurrentDb.Name) - 4) &
" temp.mdb"
Kill (strTempDatabase)



tagExit:

Exit Sub

tagError:
DoCmd.Hourglass False
If Err.Number = 70 Then
MsgBox "Unable to delete temporary database as it is locked." &
vbCrLf & vbCrLf & _
"Import cancelled."
Else
MsgBox Err.Description, vbCritical
End If

Exit_Command9_Click:
Exit Sub

Err_Command9_Click:
MsgBox Err.Description
Resume Exit_Command9_Click

End Sub

It creates the database, and the table but I can't figure out what I'm
doing wrong. I'm no expert so it may be something obvious (I don't
really understand the line that's causing the problem!).

Please help, it's driving me mad!

hi Ben,

I have the following code but every time I get to the line marked with
*, I get a Type Mismatch error.
Dim tdfNew As TableDef, RS As Recordset
* Set RS = CurrentDb.OpenRecordset(strTableName, dbOpenDynaset,
dbAppendOnly) - This is the line
It is the declaration, which causes the error.

In Access 2000 and above, the Recordset class points to ADODB.Recordset,
but the CurrentDb.OpenRecordset returns a DAO.Recordset.

So, declare the the Recordset always with its library name:

Dim rs As ADODB.Recordset

or

Dim rs As DAO.Recordset

(In your case the second declaration).

You also need to check, if a reference is set to the Microsoft DAO 3.6
library.
