Hello,

Welcome to Microsoft Newsgroup Support Service! My name is Marco Zhou. It's
my pleasure to work with you on this thread.

If I understand you correctly, you need to pass some data from ASP.NET web
pages to the XBAP application, if this is the case, there are two options
you could try out:

First option:

You could use cookie to pass data to XBAP application as follows:
At the codebehind of ASP.NET web page, you could simply write something
like the following:

// Construct the cookies.
HttpCookie cookie = new HttpCookie("MyData");
cookie.Value = HttpUtility.HtmlEncode("MyData");

//Add to the response stream
Response.Cookies.Add(cookie);

// Redirect the page to XBAP delopyment URI.
Response.Redirect("http://localhost/XBapCookieDemo/XBapCookieDemo.xbap");

And in the XBAP application, you could retrieve the cookie using the
following method:

try
{
String cookie = Application.GetCookie(BrowserInteropHelper.Source);
MessageBox.Show(cookie);
}
catch (Win32Exception)
{
}

Second option:

You could use query string to pass data to XBAP application, at the
codebehind of ASP.NET web page, you could write something like the
following:

String data = HttpUtility.UrlEncode("MyData");

// Pass the data using query string.
Response.Redirect("http://localhost/XbapCookieDemo/XbapCookieDemo.xbap?MyDat
a=" + data);

And in the XBAP application, you could retrieve the data using following
method:

String queryString = BrowserInteropHelper.Source.Query;
if (queryString != null && queryString.Length > 0)
{
MessageBox.Show(queryString.Trim('?'));
}

If you want to pass data after the XBAP application has launched, you could
try creating an ASMX or WCF service at the XBAP deployment site, so that
you could communicate data to XBAP application via ASMX and WCF service.

If you have any further questions on this issue, free feel to ask here, we
are glad to answer them.
