SYMPTOMS
When you use the Adodb.Command.Parameters.Refresh method with an Access stored query, the following error message appears:

ADODB.Command (800A0CC1) Item cannot be found in the collection corresponding to the requested name or ordinal.



CAUSE
ADODB does not support the Command.Refresh method for calling Access queries.



RESOLUTION
To work around this problem, use ActiveX Data Objects Extensions for Data Definition Language and Security (ADOX) with Catalog.Command. This will enable you to use Command.Refresh.



MORE INFORMATION
Paste the following code in a text editor, such as Microsoft Notepad, and save it as an ASP file in the \InetPub\WwwRoot folder. You can then execute this code from the browser to test the Catalog.Command.Refresh method.

NOTE: The code as provided here demonstrates the error. Refer to the comments in the code to avoid the error.   <%@ Language=VBScript %>

<% Dim adoConnection Dim adoCommand Dim adoCatalog Dim strSQLCreateProc Dim strSQLDropProc

'JetOLEDB4.0 adoConnectString="Provider=Microsoft.JET.OLEDB.4.0;" & _ "Data Source=D:\inetPub\wwwRoot\Databases\Northwind.mdb;" & _ "User ID=Admin;Password=;"

Set adoConnection = CreateObject("adodb.connection") With adoConnection .CursorLocation = adUseClient .Open adoConnectString End With strSQLCreateProc = "Create Procedure uspInsertShipper(" & _           "@parm1 VarChar(40)," & _            "@parm2 VarChar(24))" & _ "as " & _ "INSERT INTO Shippers (CompanyName, Phone)" & _ "VALUES(@parm1, @parm2)"

strSQLDropProc = "Drop Procedure uspInsertShipper" On Error Resume Next adoConnection.Execute (strSQLDropProc) On Error GoTo 0 adoConnection.Execute (strSQLCreateProc)

'* Comment this code (And uncomment the AdoX code below) to fix the error. Set adoCommand = CreateObject("adodb.command") Set adoCommand.ActiveConnection = adoConnection adoCommand.CommandText = "uspInsertShipper" adoCommand.CommandType = adCmdStoredProc adoCommand.Parameters.Append adoCommand.CreateParameter("parm1", adVarWChar, adParamInput, 40) adoCommand.Parameters.Append adoCommand.CreateParameter("parm2", adVarWChar, adParamInput, 24) adoCommand.Parameters.Refresh

'* Uncomment this code (And comment the AdoDb code above) to fix the error.

Response.Write "The parameter properties for uspInsertShipper: " & " " _ & "Name: " & adoCommand.Parameters(0).Name & " " _ & "Type: " & adoCommand.Parameters(0).Type & " " _ & "Direction: " & adoCommand.Parameters(0).Direction & " " _ & "Size: " & adoCommand.Parameters(0).Size
