We have a datagrid that it takes time to always load (see code below).  We have the same open in other apps and it's not slow.

Please advice

ooops!  (forgot the code)...

 Set cnn = Nothing
 Set rst = Nothing
 Set cnn = New ADODB.Connection
 Set rst = New ADODB.Recordset

 cnn.Open "Provider=SQLOLEDB; " & _
          "Initial Catalog=" & cdb & "; " & _
          "Data Source=" & srvname  & "; " & 
          "integrated security=SSPI; persist security info=True;"

 sSql= "select col1, col2, col3 from TableName"
 dcRecs.ConnectionString = cnn
 dcRecs.RecordSource = sSql
 dcRecs.Refresh

Open in new window

Hi.  We read it but don't know what you want us to look for or anything that points to slow connection.  Can you be more specific?

The VB6 code takes around 8 to 12 seconds to load the datagrid window.

Running the same script in MS sql studio takes less than a second.

We have another apps that has the same cnn.Open and it takes 1 second.

(we still checking whats going on... hope u can help)

Yes, it es the server name.  We had "(local)" and change it to the actual server name, and it worked fast.

Why is it that if you use "(local)" as a server name it takes longer to connect than when entering the actual "server" name?

Thanx, but can you explain why using "(local)" as a server name it takes longer to connect than when entering the actual "server" name?

If you put local then the System will have to find out the name of the local server out of the servers available. If you directly put the name then this  time will be saved.
