   A brief overview can be found here: InfoPath 2007 features that are unavailable in InfoPath 2003.

2. What are browser-compatible forms?

   InfoPath 2007 introduced the possibility to fill out InfoPath forms by using a browser such as Internet Explorer, Firefox, Netscape, or Safari. These types of forms are called InfoPath 2007 browser-compatible forms. For a complete list of browsers that can be used to fill out InfoPath forms, see Plan browser support (Office SharePoint Server).

   For more information see Introduction to browser-compatible form templates.

   Yes, you can, but you will have to install Forms Server to be able to run browser-compatible forms.

4. What is Forms Server?

   Forms Server is the extracted version of Forms Services that comes with Microsoft Office SharePoint Server 2007 (MOSS). It is sold and can be used separately from MOSS to run and fill out InfoPath 2007 browser-compatible forms.

   For more information see Introduction to Office Forms Server.

5. What do I need to be able to run Forms Server?

   Windows SharePoint Services 3.0, which you can download, install, and use free of charge.

7. How do I retrieve the value of an InfoPath field through code?

   In C# code:

   XPathNavigator nav = MainDataSource.CreateNavigator();
string fieldValue = nav.SelectSingleNode("//my:field1", NamespaceManager).Value;

   In VB.NET code:

   Dim nav As XPathNavigator = MainDataSource.CreateNavigator()
Dim fieldValue As String = nav.SelectSingleNode("//my:field1", NamespaceManager).Value


8. How do I set the value of an InfoPath field through code?

   In C# code:

   XPathNavigator nav = MainDataSource.CreateNavigator();
nav.SelectSingleNode("//my:field1", NamespaceManager).SetValue("myValue");

   In VB.NET code:

   Dim nav As XPathNavigator = MainDataSource.CreateNavigator()
nav.SelectSingleNode("//my:field1", NamespaceManager).SetValue("myValue")

9. How do I call a web service through code?

   In C# code:

   // Create an XPathNavigator object to navigate the data source of the web service
XPathNavigator nav = DataSources["HelloWorld"].CreateNavigator();

// Set the value of the parameter to pass to the web service
nav.SelectSingleNode("//dfs:queryFields/tns:HelloWorld/tns:name", NamespaceManager).SetValue("myValue");

// Call the web service
DataSources["HelloWorld"].QueryConnection.Execute();

// Retrieve the results returned by the web service
string results = nav.SelectSingleNode("//dfs:dataFields/tns:HelloWorldResponse/tns:HelloWorldResult", NamespaceManager).Value;

   where HelloWorld is the name of a data connection to a web service.
   
   In VB.NET code:

   ' Create an XPathNavigator object to navigate the data source of the web service
Dim nav As XPathNavigator = DataSources("HelloWorld").CreateNavigator()

' Set the value of the parameter to pass to the web service
nav.SelectSingleNode("//dfs:queryFields/tns:HelloWorld/tns:name", NamespaceManager).SetValue("myValue")

' Call the web service
DataSources("HelloWorld").QueryConnection.Execute()

' Retrieve the results returned by the web service
Dim results As String = nav.SelectSingleNode("//dfs:dataFields/tns:HelloWorldResponse/tns:HelloWorldResult", NamespaceManager).Value

   where HelloWorld is the name of a data connection to a web service.
