Examples
In the following example, the Import method of the IInfoPathDataImporter interface is used to iterate through the mshtml.IEnumUnknown collection of IInfoPathViewControl controls in the view of the active form.
The Import routine is the main part of a solution used to build a custom data importer. The Visual Studio project requires a reference to the Microsoft Office InfoPath 2.0 Type Library and System.Windows.Forms, with Imports statements for each as well as mshtml.Implements statements are required to generate the signatures for the methods provided by the custom data importer interfaces, including IInfoPathDataImporter, IInfoPathDataImporterFields, IInfoPathViewControl, and IPropertyBag.
Note
To build a custom data importer using a .NET class library, check the Register for COM interop check box on the Compile tab of the class properties editor.
Note
To debug a custom data importer, set a Start Action in Visual Studio to Start an external program, and browse to INFOPATH.EXE located at <drive>:\Program Files\Microsoft Office\Office12\. This option is available on the Debug tab of the class properties editor.
