Load a Graph From an External Process

GraphEdit can load a filter graph created by an external process. With this feature, you can see exactly what filter graph your application builds, with only a minimal amount of additional code in your application.

The application must register the filter graph instance in the Running Object Table (ROT). The ROT is a globally accessible look-up table that keeps track of running objects. For information about how your application can add its filter graph to the ROT, see the topic Loading a Graph From an External Process in the Microsoft DirectShow documentation.

To use this feature, perform the following steps:

1. Compile your application with code that adds a ROT entry for the filter graph.
2. Run GraphEdit.
3. Run your application.
4. In the File menu, click Connect to Remote Graph....
5. In the Select a remote filter graph to view... dialog box, select the process identifier (pid) of the second application.
6. Click OK.

To refresh the list of process identifiers, click Refresh in the dialog box.
