Summary

If your Microsoft Visual Basic 6.0 (VB6) project was created for use with Reflection version 14.1 or earlier or EXTRA! X-treme version 9.1 or earlier, it may require changes to run with Reflection 2011, 2008, or 2007.

1. Modify Reflection or EXTRA! namespace references in your code as follows.

2. In the project References dialog, use "ReflectionCOM" or "EXTRACOM" as appropriate.
3. Re-compile your project code.
