Return with event?

[russland]

Hi, I'm calling an assembly from my main WinForm. Now, that assembly is loading a file (DownloadFileGroupAsync("myFile")) in async mode. There is an eventhandler that would scream on completion of the download. Since I must return the instance to the main WinForm I wonder how I could make my method (in the invoked assembly) wait for that download to complete. How do I use the "Completed"-event in conjunction with the return.

I hope I made myself clear. The "Completed"-event should be the trigger for the invoked method to return the file to the main WinForm.

Any clue how I could bind that event to the return?

Any hint highl apperciated. Thanks

Normally,

you would make a call to download the file and attach to the completed event.

If you want to get the file path you could do that with a custom event delegate that includes the path (if you have access to the component doing the download)

example:

public delegate void CompletedEventHandler(object sender, string filepath);

Then you create your custom event:

public event CompletedEventHandler downloadcomplete;

Hope that gets you started
