Subject: C extension with progress bar

Hi,

I have a ruby extension which shows a progress bar window.

The progress bar shows the progress of a loop in the ruby code.For each
iteration of the loop I call an extension method that sets the current
progress through the PBM_SETPOS message.

The progress bar is actually shown.The problem arises when I want to
implement a cancel button in the progress window.

While the progress is updating the window becomes unresponsive and
cancel button click does not work.

I tried to update the progress in C code through a separate thread using
CreateThread but it does not show the progress at all.

Kindly suggest solution to fix this problem

Thanks in advance and let me know any other details are required.

Simi
