Hi game-master,

I am using a trusted connection (windows authentication) and used as User Id and Password the same in the WITH command value. But I have the same issue.  

 

by: game-masterPosted on 2009-08-18 at 00:46:30ID: 25120790



on which part of the code the error occurs?

 

by: game-masterPosted on 2009-08-18 at 00:59:22ID: 25120842



if your using trusted connection, user ID and password are not necessary.

try sumthing like this...


    Set cn = New ADODB.Connection
      With cn
        .CursorLocation = adUseClient
        .Provider = "SQLOLEDB"
        .Properties("Integrated Security") = "SSPI"
        .Properties("Persist Security Info") = False
        .Properties("Initial Catalog") = "TessySql"
        .Properties("Data Source") = ".\SQLExpress"
        .Open
     End With
