Dialog Box Filter API (Standard 7 SP1)

7/8/2014

The Dialog Box Filter API exposes a set of functions that enables you to implement your own filtering, and optionally, your own window interrogation. This allows native and managed code to implement an in-process (DLL) COM object that the Dialog Box Filter service can load and use.

To enable support for the Dialog Box Filter API, add the Dialog Box Filter API to your component by linking with DialogFilterXmlFilter.tlb from the EmbeddedSDK\lib folder.

There is a sample Visual C++ project demonstrating a custom dialog box filter. The sample project is located in the Samples\CustomDialogFilter folder.

In This Section

The following table shows the classes that are provided in the Dialog Box Filter API.
