hey guys i have an ETL winform in VB 2005

and it's like-- off in la-la land.

i know it's doing things-- it's happily crunching away. but i'm
confused about what i need to do to make the main form refresh... or
repaint..

it's like.. it just looks hung (sorta like me lol jk)
and i just want something that LOOKS AND ACTS like a real app.

what can i do to make the form repaint itself/?

thanks

Oh... so, it's only slightly hung, eh? ;-)

Well, I'm a VB6'er so all I can suggest is DoEvents. The functionality that
DoEvents provides will need to be there, regardless of any syntax
differences, if the form has to repaint. One thing that seems to confuse a
lot of people is... Screen updates are low priority. If they suddenly became
high priority, every app known to man would instantly slow to a crawl. The
trick is to find that magical combination of "let the screen update" vs
"crunch the code and spit out the results"

If you, or someone you know, is comfortable with quick VB6 migrations, here
are a couple of things that may help find that "magical combination"

Here's a contest winning article....

.....and a project built using techniques from that article....
