Hourglass VS. Processing Bar

[Chris Kelleher]

Hi All,

One of the marketing guys said that the Hourglass while waiting was not very
informative.

So ...
Is there any easy way to bring up a Processing bar ? OCX ?
Would the Processing Bar impact performance in noticeable way ?

I thought it might be neat to see a Processing Bar when loading a large text
file into an Editor Widget.

(Progress 8.3b, Win NT/95)

Regards,

Rich

How much information does a marketing guy expect?
Seriously, I think it can't be done if the load-file operation is just
one single statement that does not provide a progress trigger.
(where progress trigger is a trigger that says "60 lines loaded" or
"12 kilobyte loaded" so far). You could perhaps break the large file
into a lot of small chunks and write a loop that appends all these
chunks into the editor widget while you redraw the progress bar.
It would have negative impact on the overal performance.

I sucessfully used the Animation control that comes with VB6, and run an
.avi like the 'flying folders'.
I didn't notice any extra overhead, and I don't have to call back to update
a percentage, like a progressbar.

I dont think you can do it to show the progress of a single
statement, but if you are looping then you can.
I couldn't find a decent progress bar when I was looking ages ago.
The Msoft one is a little on the crap side.
The progress way is to have 2 rectangles. One white the other blue.
Superimpose the blue one on the white one and increase the size
of the blue one and hey presto, quick and cheesy progress bar.
