COM ADO and SQLXML v3

Hi,

I'm in the process of updating an HTA hosted application to SQL Server 2005 Express, using javascript with ADO for database access. I have one function to which I pass an SQLXML query template or updategram for all database queries and updates:

function doSql(sXml) {
var cmd = new ActiveXObject('ADODB.Command');
var conn = new ActiveXObject('ADODB.Connection');
var strmIn = new ActiveXObject('ADODB.Stream');
var strmOut = new ActiveXObject('ADODB.Stream');
var xml = new ActiveXObject(sDOM);
xml.async = false;

try {
conn.Provider = "SQLOLEDB";
conn.Open("Provider=SQLOLEDB.1;Persist Security Info=True;"+
"Initial Catalog=CGIS;Server=(local)\\ocean;Integrated Security=SSPI;");
conn.Properties("SQLXML Version") = "SQLXML.3.0";
cmd.ActiveConnection = conn;
cmd.Dialect = "{5d531cb2-e6ed-11d2-b252-00c04f681b71}";
strmIn.Open();
strmIn.WriteText(sXml);
strmIn.Position = 0;
cmd.CommandStream = strmIn;
strmOut.Open();
cmd.Properties("Output Stream").Value = strmOut;
cmd.Properties("Output Encoding").Value = "UTF-16";
var iCount;
cmd.Execute(iCount, null, 0x400);
conn.Close();
xml.load(strmOut);
return xml;
} catch(e) { alert('A database error occured: \n'+e.description+'\n\nQuery:\n'+sXml); }

I understand that SQLServer 2005 has SQLXML built in, which can be accessed using ADO.Net. Can it also be accessed using COM ADO? When I changed the connection string to this:

conn.Open("Provider=SQLNCLI.1;Integrated Security=SSPI;Persist Security Info=False;Data Source=\\.\pipe\SQLLocal\SQLEXPRESS");

I get this error:

'A database error occured:
SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF].'

Sounds like a connection string error however this was the connection string I pulled out of a .udl file that connected successfully.

Any help/suggestions greatly appreciated!

Try changing the provider to see if that's it. My bet is that it is something to do with the network connection settings, so look in Books Online in the Database Engine section to learn more about the settings and various issues they have. You can also check out this article:
