Displaying a large amount of data quickly (VB6)

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I need to make a very large list (up to 250,000 lines) of array
entries visible to the user as quickly as possible. I found that a
standard text box can't hold that much data, so I am now using a rich
text box. It works, but it takes a long time to load.

It takes so long that I was prompted to implement a "Loading..."
indicator along with a progress bar. By so doing, I can now see that
it gets slower and slower as more data is appended. The mouse also
does an annoying flicker between hourglass and normal while this is
going on. I did provide the user with a way to bail out of this.

But the question is: Is there a quicker way? One that eliminates the
mouse flicker problem?

Thanks
Tom
