Basically, my data source is a piece of hardware connected throught a serial cable. This connection is very slow; it takes about 3 seconds to fetch current data which are constantly changing.
Now, there is a need to watch different resources through the same cable as well, so when you run two instances of my app then the refresh takes 6 second. Potencially, there is no limit of how many views on the resource there is going to be (within a reason).
So, I had an idea of refreshing just fields which are currently visible to speed everything up. After all, why waste resources when nobodu is going to see it.
I was interested in native windows. The real visibility for a user.
What is the diffucult way?
thanks,
Martin
