quick C# question

[VJ]

Hello,

I have a small C# question. On a form, I have a progressbar and sort of a todo list. The todo list shows the current action being performed, the progress bar displays the progress of this action. All actions are dealt with in a single background worker.

Some actions require a continuous progressbar (as I can predict the amount of steps required), so for these the style is set to "continuous". For other actions, I would like to set it to "marquee". But just setting the style doesn't work...

I found in the help that "continuous" is only valid if visual styles are not enabled, whereas "marque" is only valid when visual styles are enabled.
What is this "visual styles" thing?
And can I change the appearance of the progressbar this way?
Thanks!

I don't know about the style thing.
Maybe it's a property that can't be changed after they are instantiated.

But you might be able to solve it simply.
Create two progress bars, one of each style.
Then just show and hide them as needed.

Hey, that is an idea (hadn't thought about that... )!
But what about that "visual styles" comment on MSDN? It makes me think that one can either have continuous bars, or marquee bars, but not both...

But I'll give it a go!

Well?

Sorry, haven't gotten round to trying it... I seem to be running into memory exception issues from my C++ dll, despite the fact that it has full exception handling.
