Flex and C# Communication (Tutorial)

While waiting for Apollo i decided to check out what can be done with flash on the desktop today.
I`ve never been into microsoft programming but found out that it`s extremely easy to write your own wrapper for swf files in c#.
This gives you the opportunity to write your own Zinc like projector tool. As a start i implemented simple file I/O and a way to start and play cds.
The coolest thing i was able to do was to include microsofts speech recognition and make my flex application react to speech.
The app is quite simple but cool! I have a button on stage and if i say “left” it will jump to the left or if i say “green” it`s text becomes green.

I decided to write a small tutorial about how to embed an swf file into a c# project and how the communication works. Well this is my first public
tutorial so be patient. I had several dificulties:

- english is not my native language
- how to describe things and make them understandable
- how to show code in a nice way

Well i think i failed in coping with all of those challenges :-(

Anyway if i find the time i want to extend this article to the point with the speech engine.
If you want to help me i would be very interested in suggestions and corrections.

Check it out here.

    Hi Dan,

    where exactly have you placed the dll`s?

  6. Dan on January 24th, 2007 6:25 pm

    Hi!! Admin,

    I placed the dll’s in my project directory, as your article said. I think it’s correct, so in the VStudio I can see the shockwave object, but when I try to put it on a winform I have the error message we talk about.

    Thanks for your interest!!!

    Dan.

    Very nice tutorial, explained well. I have been developing Flex and AIR applications and have been longing for a way to call out to C# or COM components for a while.

    Now … if there was just a way to call a C# or COM component from a Flex AIR application, I would really be excited! I am disappointed at the lack of interaction with the local system that Flex AIR allows. General file access is great, but I wish you could launch other processes and call other components. Maybe in a future release.
