I wrote a little program the other day that scanned through a multi-megabyte file looking for certain bit sequences and then decoding them. I was surprised how slow it ran. After some testing I ran across some interesting observations. Take this simple code below. Code: Sub App_Start form1.Show form1.Refresh For i = 1 To 100000 label1.Text=i' label1.Refresh form1.Refresh Next label1.Text="done" form1.RefreshEnd Sub The code above takes about 5 minutes to run. :sign0161: Change the form1.refresh to label1.refresh and it runs in 10 seconds! Comment out label1.refresh and it runs in 6 seconds!! Comment out label1.text and it runs in less than second!!!! So the point here is that from now on I'll make sure my number crunching, loops, etc.. are done without refreshing the data on screen if I want speedy code. We are talking about 2 orders of magnitude in difference here!! Going to go back and rewrite some of my code now. This is was all done on the desktop. I haven't tried this on a PPC yet.
