Remarks
The COMAddIns object returned by the InfoPath ComAddIns property is implemented in the Microsoft.Office.Core namespace. The Microsoft.Office.Core.COMAddIns object provides information about the collection of InfoPath COM add-ins that are registered in the Windows registry of the user's computer. To access the members of Microsoft.Office.Core namespace, you must first add a reference to the Microsoft Office 14.0 Object Library on the COM tab of the Add Reference dialog box in Visual Studio.
To use the Microsoft.Office.InfoPath.ComAddIns property to access the Microsoft.Office.Core.COMAddIns object, you must cast the InfoPath ComAddIns property to the Office COMAddIns type as shown in the code example.
This member can be accessed only by forms opened from a form template that has been configured to run with full trust using the Security and Trust category of the Form Options dialog box. This member requires full trust for the immediate caller and cannot be used by partially trusted code. For more information, see "Using Libraries from Partially Trusted Code" on MSDN.
This type or member can be accessed only from code running in forms opened in Microsoft InfoPath Filler.
