    pPrintSettings As IPropertyBag, _
    punkViewControls As IEnumUnknown _
)
'Usage
Dim instance As IInfoPathDataImporter
Dim pPrintSettings As IPropertyBag
Dim punkViewControls As IEnumUnknown

instance.Import(pPrintSettings, punkViewControls)

void Import(
    IPropertyBag pPrintSettings,
    IEnumUnknown punkViewControls
)

Parameters

• pPrintSettings
  Type: Microsoft.Office.Interop.InfoPath.IPropertyBag

  A collection of print settings.

• punkViewControls
  Type: IEnumUnknown

  An mshtml.IEnumUnknown collection of controls in the view.

Remarks

For more information about programmatically importing data into an InfoPath form, see the InfoPath Developer Portal on the Microsoft Office Developer Center.

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.
