Refresh a form

[Li Pang]

Hi,

I used a form tp populate data. When the data is still processing, I leave
the form and go to some external application, and then back the my
application again, the form becomes blank. The form is refreshed/coming back
until the data process is completed. I want to know if there is a way to
refresh the form (avoid blank form)?

Thanks in advance

I saw there is another thread talking about this issue. The solution is using
Application.DoEvents()

A solution, not always the most apriciated one.

You may want to perform processing in a separate thread:
