Re: Win32::GUI sending Windows messages between threads

Here's something that I personally would try.

Launch a thread and create Win32::GUI::Timer object. When the timer goes off, have it check to see if the thread is joinable. If it's not, do nothing. If if it is, then you can join the thread and kill the Win32::GUI::Timer object.

However, if you're needing the thread to continue running for a long time and return stuff periodically, you can tweak the above steps so that you're checking on shared variable(s) instead of checking to see if the thread is joinable.

I definitely need the child thread to run for a long time -- possibly the entire lifetime of the program. Sounds like you're suggesting I essentially poll inside the timer handler. I am considering that as a fallback if I can't get the message passing thing to work, but ultimately it's polling and it's inefficient and the message passing approach seems much better, so I want to pursue it first.
