Send Message to Parent Thread

[joe_pool_is]

I've got an application with a thread that works great except for one thing: I don't know how to get the thread to signal and pass information back to the main form.

 

What is the best way to do this in VB or C# 2005?

Depending on your needs the two easiest ways are:

1) Pass a callback function to the thread so the thread can call this method as a means of signalling the parent.

 

2) Declare an event the thread can raise to signal the parent.

 

Another possibility is if the parent thread has a message pump (normally means it is a UI thread) the background thread could use either the SendMessage or PostMessage APIs to signal the parent.

 

Personally I would choose either the callback or event based methods though.

Thanks for the idea. I was able to Invoke a Delegate with a TextBox Control.
