The below VB.Net 2005 code errors out on the line

        qryTable = oSheet.QueryTables.Add(conn, oSheet.Range("A1"), "Select * from tblActiveIngrediantAnalysis")

with the below error message.  Please help to resolve.  Thanks.

System.ArgumentException was unhandled

Dim oExcel As New Excel.Application

        Dim oSheet As Excel.Worksheet

        oExcel.Workbooks.Add()

        oSheet = oExcel.ActiveSheet
 

        Dim conn As New SqlConnection(My.Settings.BRDWorklsates)

        conn.Open()

        Dim qryTable As Excel.QueryTable

        qryTable = oSheet.QueryTables.Add(conn, oSheet.Range("A1"), "Select * from tblActiveIngrediantAnalysis")

        With qryTable

            .RefreshStyle = XlCellInsertionMode.xlInsertEntireRows

The first parameter should be a connection string, not a Connection object.

Thanks Rory.  Now I have a subsequent error:

"Exception from HRESULT: 0x800A03EC"

When I try:
qryTable = oSheet.QueryTables.Add(conn.ConnectionString, oExcel.ActiveSheet.Range("A1"))

or

qryTable = oSheet.QueryTables.Add(conn.ConnectionString, oExcel.ActiveSheet.Range("A1"), "Select * from tblActiveIngrediantAnalysis")


Thoughts?

What does the returned connection string look like? It should start with "ODBC;" or "OLEDB;"

Well, it was this:

conn.ConnectionString = "Data Source=usgrrd3;Initial Catalog=BRDWorkslates;Integrated Security=True"

So I changed it to

Dim conn As New OleDb.OleDbConnection(My.Settings.OLEDB_Connection)
and conn.ConnectionString now equals
"Provider=SQLOLEDB.1;Data Source=USGRRD3;Integrated Security=SSPI;Initial Catalog=BRDWorkslates"

I still get the same error.  I'm trying to directly access a SQL Server.  Am I using the wrong approach.  Basically I'm wanting to quickly dump the results of 15,000 records from a SQL Server 2005 into Excel 2007 using VB.Net 2005

Is Your Active Directory as Secure as You Think?

More than 75% of all records are compromised because of the loss or theft of a privileged credential. Experts have been exploring Active Directory infrastructure to identify key threats and establish best practices for keeping data safe. Attend this month’s webinar to learn more.

Your connection string would need to be:
"OLEDB;Provider=SQLOLEDB.1;Data Source=USGRRD3;Integrated Security=SSPI;Initial Catalog=BRDWorkslates"

That now works, Thanks.  Is there a way to add that OLEDB via the Project Settings form, so that I would not have had to append it as shown below?

qryTable = oSheet.QueryTables.Add("OLEDB; " & conn.ConnectionString, oExcel.ActiveSheet.Range("A1", "A1"), "Select * from tblActiveIngrediantAnalysis")

Not that I know of, no. The prefix depends entirely on the type of connection - whether it's OLEDB, ODBC, web etc.
