PRB: Collating Sequence Error Opening ADODB Recordset the First Time Against an Excel XLS

Symptoms

Opening an Microsoft Excel spreadsheet from within Visual Basic in Visual Studio 6.0 Service Pack 3 (or later) Integrated Development Environment (IDE) with the Excel/ODBC/ISAM driver generates the following run-time error:

Run time error '-2147467259 (80004005)' : [Microsoft][ODBC Excel Driver]Selected collating sequence not supported by the operating system


This problem occurs every time that you run the code within the Visual Basic IDE.

NOTE This error does not occur if the all the fields are selected in the SQL statement, for example:
SELECT * FROM ...
Also, this problem does not occur within a compiled EXE.

Cause

This is a problem within the Visual Basic IDE starting with service pack 3.

Steps to Reproduce Behavior

  1. Create a spreadsheet in Microsoft Excel 97 or Microsoft Excel 2000 and place the following values in the prescribe fields:
    • A1 = F1
    • B1 = F2
    • C1 = F3

  2. Save the spreadsheet and create a DSN pointing to it.
  3. Start Visual Basic 6.0 from Visual Studio 6.0 Service Pack 3 or later.
  4. Create a new Standard EXE and set a reference to Microsoft Active Data Objects. Paste the following code into the form:
    Public Sub Form_Load()

    Dim constring As String
    Dim Connection As New ADODB.Connection
    Dim cmd As New ADODB.Command
    Dim rs As New ADODB.Recordset

    ' define a DSN IMPORT-XLS, using the Excel ODBC driver, and point it to the xls file
    constring = "Provider=MSDASQL;DSN=IMPORT-XLS"

    Connection.Open constring
    Set cmd.ActiveConnection = Connection
    cmd.CommandType = adCmdText

    ' The following .CommandText causes the error, but only the first time it is run within the ide.
    cmd.CommandText = "Select F1, F2 from ""Sheet1$"""
    ' The following .CommandText will not cause the error.
    ' cmd.CommandText = "Select * from ""Sheet1$"""

    rs.CursorLocation = adUseClient
    rs.CursorType = adOpenStatic
    rs.LockType = adLockReadOnly
    rs.Open cmd
    While Not rs.EOF
    MsgBox rs.Fields(0)
    rs.MoveNext
    Wend

    End Sub
  5. Make the necessary changes to the ConnectionString.
  6. Run the form.
  7. The first time the form runs, the error appears; it does not appear in subsequent runs.
