C# and Excel QueryTable Problem

Hi ,



Can you provide some sample of querytable in excel using C#. I am
working for some assignment, but the query table.add method gives
error.

I wonder what the problem is. I am new to programming of excel and
querytables. We are using Excel 11.0 libraray in C#.



The code snippet:-



static void Main(string[] args)

{

try

{

Excel.Application oXL;

Excel._Workbook oWB;

Excel._Worksheet
oSheet;





// start Excel and get
Application object

oXL = new
Excel.Application();

oXL.Visible = true;





// get a new workbook







oWB =
(Excel._Workbook)(oXL.Workbooks.Add(System.Reflection.Missing.Value));

oSheet =
(Excel._Worksheet)oWB.ActiveSheet;









// I had a problem
here;

// import data to excel
sheet


oSheet.QueryTables.Add(" server=XXXX;database=XXXX;uid=sa;pwd=sa;
",oSheet.get
_Range("A1",
"A1"), "exec prc_X");







// NOTE: for the 3rd
argument I do a stored procedure

//call, but this can
also be a straigh sql statement...







// the QueryTables
collection of the worksheet seems to

//be indexed starting
at 1


oSheet.QueryTables[1].Refresh(true);

oXL.Visible = true;

}

catch (Exception ex)

{

Console.WriteLine
(ex.Message + "\n" + ex.StackTrace);

}



The error message is as following:-



Message           "Exception from HRESULT: 0x800A03EC."
String

_stackTraceString          "   at
System.RuntimeType.ForwardCallToInvokeMember(String memberName,
BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData&
msgData)\r\n   at Excel.QueryTables.Add(Object Connection, Range
Destination, Object Sql)\r\n   at
ConsoleApplication2.Class1.Main(String[] args) in c:\\documents and

Your prompt assistance is highly expected. Thanks for your time and
effort.
