Hi,
I have to process a large data loading in my form. In order to give a
feedback on the loading status, I'd like to display a progressbar in a
popup, in the middle of the screen. How can I do that, as the
progressbar is not in the same form as my data structures?
Thx 6 1919
Sam,
There are hundreds ways that data is stored. Than there are probably
hundered ways that data is processes. What answer do you want from us a link
to the progressbar on MSDN?
Cor
Hi Cor,
That's true, I haven't been very clear.
I'm actually building a tree and I don't know how much time it's gonna
take or even how many items will be added, as the data come from many
different stored procedures. Therefore I'm thinking about showing a
progressbar during the time of the tree construction. Basically I would
show the form that contains the bar before calling my BuildTree
function and I would close it as soon as the function finished. I would
like the bar to actually move from left to right and then from right to
left, kindof a fancy effect.
How can I achieve that?
Sam,
What is the in memory data the stored procedures point to. When it is a
dataset or datatables, how many Fill you have to handle?
If it is a datareader, than you can take two progressbars above each other.
In my idea is the simplest approach counting the stored procedures and take
those as steps. The progressbar documentation on MSDN does that.
If you want a procedure that I will not advice however because it is often
asked and therefore this sample (however you can see in that how to use a
progressbar). http://www.windowsformsdatagridhelp....6-fc0d5c470f53
I hope this helps,
Cor

thanks, that's a cool and useful link!
May I ask a question regarding the code on the link you gave me? In the
following block of code:
for( int i = 0 ; i < 100 ; ++i )
{
callback.SetTex t( String.Format( "Performing op: {0}", i )
);
callback.StepTo ( i );
if( callback.IsAbor ting )
{
return;
}
// Do a block of work
if( callback.IsAbor ting )
{
return;
}
}
When the author wrote //Do a block of work, I don't understand how you
can do different operations at each loop. Because obviously since I'm
building a tree, at each iteration of the for loop, I would like to
call a different method that handles building a sub-part of my tree.
(it's the way it currentely works). So how can I do that in this loop?

Hi, thanks for the previous advice on progressbars with showing the
percentage. I would now like to create a less clunky version.
I.e at the moment my progressbar shows 7 separate steps. Some steps can take
seconds to process, but others could take upto 10 minutes (leaving the users
thinking nothing is happening!).
Is there a way to show the progressbar smoothly increasing until the final
step has finished instead of clunking it's way...

In other programming languages I've been able to easily change the style
of a progress bar between smooth and blocked. I find that is either
really hidden or impossible in .NET. Am I missing something?
I'm shocked that .NET doesn't have a style property for the progressbar
control!

Hi
I'm currently developing a Windows application. At the start of the
application I load several tables into datatables in a dataset. I also use
a progressbar to show the user how much percent of the total is already
loaded. But I do this in a dirty way: I increment the progressbar with the
same number after each table, but not all tables contain the same amount of
data. I solved this with starting an other thread to increment the...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
