MORE INFORMATION

Steps to Reproduce Behavior

1. Create a default ATL COM AppWizard project.



2. In ClassView, right-click on the root node and select New Class. Add a new ATL Class Interface pair.



3. Open the project's IDL file in the Source editor.



4. Add five blank lines anywhere above the interface you added as part of step 2.
   
   NOTE: Do not save anything at this point. The unsaved change is key to causing the problem.



5. In ClassView, right-click on the interface created in step 2 and select Add Method. Complete the Add Method dialog box and click OK.
   
   RESULT: The error described in the SYMPTOMS section is displayed. Click OK to dismiss the error dialog box and click Cancel to dismiss the Add Method dialog box.



6. Manually save the project's IDL file and repeat step 5.
   
   RESULT: The error does not occur.

1. In the project's IDL file, add a source file comment above or below any method or property in any declared interface.
   
   NOTE: Do not save anything at this point. The unsaved change is key to causing the problem.



2. Repeat steps 5 and 6 from CASE 1.
