Threads and Interrupts in Windows CE 5.0

Hi Everyone,

I used the code below I found that the progress bar movement is not smooth, there is some struck during the movement of the progress bar initially i kept the sleep time as 50 and now reduced to sleep(1). Even I am getting the struck in the movement of the progress bar.

m_CtlTempoBar is the member variable for the Progress bar.

Looking forward to hear from you ASAP.

Thanks & Regards,
Gan
