The functions in a DLL are generally designed as passive. That is they only return information when requested by the controlling application. If you need the DLL to be active then you will need to register a callback in the application to receive the data.

To keep it simple, the C++ function should just find the names and return the found names to WPF.

A message isnt the best solution, but some callback delegate to change the displayed data. Best is to use some dispatch to avoid blocking and threading issues of the software.

Read my article about C++ and C# interaction for some example code.
