Word Processing Document API - Embed Images into a Mail Merge Template

This example implements the IUriStreamProvider to insert images from a database.

Implementation Details

The INCLUDEPICTURE field in the template has a nested MERGEFIELD that refers to the CategodyID field from the database. The "dbimg://" prefix is a stream generated by the IUriStreamProvider implementation. The GetStream method parses the received URI (the INCLUDEPICTURE field), finds the required data row, and returns the MemoryStream with an image.

Tip

You can use a DOCVARIABLE field to insert images to a template. Refer to the following topic for more information: Handle the CalculateDocumentVariable Event to Insert a Document Element
