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
