How to unwrap SemiTrust's objects?
An MSDN's tutorial did the following:

private Microsoft.Office.Core.CommandBars UnwrapCommandbarsObject(
    Microsoft.Office.Interop.InfoPath.SemiTrust.ObjectWrapper
commandBarsWrapper ) {
    Type t = commandBarsWrapper.GetType().BaseType;

    Microsoft.Office.Core.CommandBars objCommandBars =
        (Microsoft.Office.Core.CommandBars)t.InvokeMember( "InnerObject",
        BindingFlags.Public | BindingFlags.NonPublic |
        BindingFlags.Instance | BindingFlags.GetProperty,
        null, commandBarsWrapper, null);

    return objCommandBars;
}

to access the CommandBar. I need to access the thisXDocument.DataObjects
to modify query parameters as in JavaScript. In JS it would be:

strSqlCommand =
XDocument.DataObjects.Item("SalesSummary").QueryAdapter.Command;

strSqlCommand = strSqlCommand.replace(/@Ending_Date='[^']+'/,
"@Ending_Date='" + SqlDateTime(dtEnd) + "'");

How to access the Command property?? It's not there in the C# object!
Ms experts????

thanks!

Make sure you have the right type of object. E.g. ADOAdapter, not just
QueryAdapter. Cast as needed.

How could I know to which type perform the cast?

One way is to use the InfoPath help integrated into Visual Studio. Go to
Help, Search, filter on Microsoft Office InfoPath2003, and search for
Command.

This is also covered in Chapter 6 of the book below.

Thanks Matthew, I found the help very useful.
Btw I'm working with a web service so I used:

WebServiceAdapter2 wsA =
(WebServiceAdapter2)thisXDocument.DataAdapters["ElencoSchede"];

What I have to do is change a parameter of the WebMethod, to refresh the
query. I didn't find any property/method to do so.

I did it using a DOMDocument50Class object, I copied into it the

thisXDocument.DataObjects["ElencoSchede"].DOM

to replace the query value: I wasn't able to selectSingleNode directly
on the original DOM because of namespace's issues, actually I had to set
the needed namespace on the new object.

It's quite a long way to perform a simple task, I wonder if I'm missing
something about the WebServiceAdapter2 capabilities.

thanks

The adapter doesn't do anything special with the DOM (you can also call
GetDOM("elencoschede")). You will always have to deal with namespace issues
when using xpath. Typically I set namespace prefixes early in the process
(e.g. in the onload event, or immediately after calling Query).

You can also use rules or default values to set parameters in the web
service.
