QAxObject and msvc

mrdebug

Hi. I'm trying to connect to a sql server by ado using the component QAxObject and these lines of code:

QAxObject *connection = new QAxObject("ADODB.Connection");
connection->dynamicCall("Open(\"Provider=SQLOLEDB.1;Integrated Security=SSPI;Initial Catalog=Inaz;Data Source=SERVER02\")");

// Execute query and get recordset
QAxObject *recordSet = connection->querySubObject("Execute(\"select column01 from table01\")");
// Get fields
// or check https://msdn.microsoft.com/en-us/library/ms681510(v=vs.85).aspx to see what you can do with and how to use a recordset
QAxObject *fields = recordSet->querySubObject("Fields");

But I obtain this error:
-2147467259

The example
http://wiki.qt.io/Using_ActiveX_Object_in_Qt

goes to crash.

How can I do to resolve my problem?

After many tries the software works using an ado connection through odbc but not directly to a sql server.

Have you got any idea?
