Removing unused map IDs

Map files (also known as header files) are used with all types of context-sensitive Help. They contain topic IDs and map numbers. The map number follows the topic ID in a string that looks like this:

#define ID_PizzaDeliveryForm 101

Why remove unused map IDs?

It's possible that another map file might eventually use a map number that is assigned to an unused map ID. Duplicate map numbers cause context-sensitive Help to not work properly. Also, it's easier for authors to find the valid topic IDs and map numbers if the obsolete ones are removed from the project.

To remove an unused map ID:

  1. Click the Project tab.

  2. Open the Context-Sensitive Help folder.

  3. Open the Map Files folder.

  4. Right-click the map file that contains the unused map IDs.

  5. Select Remove unused map IDs.

  6. Click each file to select individual map files.

  7. If you want to remove unused map IDs in every map file in the project, choose Select All.

  8. If you want to remove all map file selections and select them individually, choose Clear All.

WARNING! Before you remove map IDs, check with your developer and make sure that you won't need to use them in the future. You can always create them again, but you should not get into the habit of removing unused map IDs.
