I am converting a VFP 9.0 application to .NET gradually in bits, right now i am adding .NET C# usercontrols to foxpro forms and i have been succuessfull so far. I am trying to hook foxpro event handlers to the .Net control events using a foxpro function EVENTHANDER() to no success so far ! i need to use these event listeners to know, pass data and do action in the foxpro environment based on the actions on the .NET usercontrol. Anyway with an idea ?

Without seeing what you've done to expose the .NET controls to FoxPro, it is hard to say what needs to be done. You really need to provide your code.

Most likely either you did not set ComVisible in your build configuration or you did not mark the event as public and may be missing your com visible decorators as specified in that article. Also did you register your .NET component with COM?

Since you also have an article giving you the steps, I recommend you write an email to the author to see if the author may have suggestions for you as well. I would also recommend double checking every step shown in that tutorial and rechecking that you got everything correctly. It is too easy to have a simple typo ruin a good day. ;)
