Showing a progress bar as a progress of thread executing in the c++ dll

[ajitm]

Hi Friends

I am working with C#, C++(dll) based project.

I am trying to show a progress bar as a progress of thread executing in the c++

dll. I want to show the progress bar as a result of amount of work preformed by

thread but the GUI gets hanged.

So Please tell me how we can updated the GUI (progress bar).

Thanks for your help
