Update an excel sheet using VBA/ADO

Question

When I execute this function I get a run time error, "Operation must use an updateable query". What is causing it?

Function updateConfigFile(strQuery As String)

Dim cnn As ADODB.Connection         
Dim objMyCmd As ADODB.Command

Set cnn = New ADODB.Connection
Set objMyCmd = New ADODB.Command

constConfigFile = "MyWorkbookName"

With cnn

    .Provider = "Microsoft.Jet.OLEDB.4.0"
    .ConnectionString = "Data Source=" & ActiveWorkbook.Path & constConfigFile & ";" & _
        "Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"";"
    .Open

End With

strQuery = "update [test$] Set [test]='Hello' WHERE [Test]='h'"

objMyCmd.CommandType = adCmdText
objMyCmd.CommandText = strQuery
objMyCmd.ActiveConnection = cnn

objMyCmd.Execute


Set objMyCmd = Nothing
Set cnn = Nothing


End Function

Answer 1

Get rid of IMEX=1 from your connection string. That works for me.

.ConnectionString = "Data Source=" & ActiveWorkbook.Path & constConfigFile & ";" & _
    "Extended Properties=""Excel 8.0;HDR=Yes;"";"
