Cannot update. Database or object are read-only

I have to build application Excel (interface) - SQL Server (backend)

I've created Data Source File "test.dsn" and tested succesfully.
SQL Server database in on the other machine.
This is a code that I am using.

And error message I am geting is "Cannot update. Database or object are read-only".

Dim cn As ADODB.Connection
Dim strSQL As String

Set cn = New ADODB.Connection
cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=C:\Documents and Settings\pd\Desktop\Development\test.xls;" & _
"Extended Properties=Excel 8.0"


strSQL = "INSERT INTO [DSN = test.dsn].Region Values(5, 'ab');"


cn.Execute strSQL

cn.Close
Set cn = Nothing

Read-only of databse properties is not selected.If I get it right you're attempting to insert a row into excel. As long as I know it's not possible because you cannot update, insert records throught Jet provider. mojza|||Your query is unclear . Understanding you are trying to update region table In sql database .
if that's case you should then rather open an ODBC or OLE DB connection to SQL server

cn.Provider = "sqloledb"
cn.Properties("Data Source") = ServerName
cn.Properties("Initial Catalog") = DatabaseName

' If Windows NT authentication.
cn.Properties("Integrated Security")= "SSPI"

'If SQL Authentication
cn.Properties("User ID")= UserID
cn.Properties("Password") = pwd

' Open the database.
cn.Open

Dim strSQL as string

strSQL "INSERT INTO dbo.Region Values(5, 'ab')"

cn.execute strSQL

cn.close
set cn = nothing
