Auto-pulsing wxProgressDialog?

[Rooney, Mike (ext. 324)]

Hello everyone. I am looking for a progress dialog that basically just moves along and starts over again until it is told to stop or destroy. I have seen these in Windows and other places all the time however not in wx. Normally I hate progress dialogs that don't actually show progress, however for our current application a call is made to a module that could take awhile and we have no way of getting actual progress, but I want the user to know the program hasn't frozen.

I have tried using a wxTimer which calls Pulse() on the ProgressDialog every 100 milliseconds, however that didn't do anything while the function call was running, defeating the entire purpose. I also tried making a little class that Pulses the dialog and running that in a thread, which also didn't work. Maybe the function call is taking up all the CPU and that is why the timer and thread didn't work? I once had the function call crash and then the dialog pulsed along as I would expect, so that seems to tell me what I am doing is right but it isn't getting enough priority. This is why I thought if there was a built-in way to do this in wx it might solve the problem.

Does anyone have any ideas as to how to solve this issue?

Thanks in advance,
Mike
