progress bar

[Sergey Bogdanov]

Hello,

I'm trying to implement progress bar for calculations. I opened dialog
(none-modal) with ProgressBar and set Max value for ProgressBar with
nrecords. In the loop I increase progress value by 1.

Forms("Progress")![Progress].Max = nrecords
Forms("Progress")![Progress].Value = 0
Do While Not rst.EOF
rst.Edit
rst![ANSumma] = rst![NLitri] * rst![rate]
rst.Update

Forms("Progress")![Progress].Value =
Forms("Progress")![Progress].Value + 1

rst.MoveNext
Loop
rst.Close

I've noticed that Access has been hanging in this loop. The Access stops
redrawing itself. Is there any universal solution for large amount of
calculations? What about timer?

Thnx,
Sergey

Hi,
Try adding DoEvents within yout loop.

I need to make a loading screen to show progress while my projector loads
from CD-ROM.
How do I do this?

I have asked this before and recieved only one suggestion which was to load
graphics off the stage over a period of frames and extend a progress bar as
each frame loads.

Is there any other way of doing this in lingo? Would I use a stub projector
??

Very much appreciate some help on this

Regards,

Flashster

The initial delay is that unnerving moment while the projector is
loading with no indication things are progressing. There are 3rd party
sub launcher applications that quickly put up a static greeting image
while the projector is taking perhaps 30 seconds to start up.

There's said to be an undocumented build in loading screen founction
enabled by placing projectorNane.bmp file in with the projetor.

Apart from using a splash screen, no lingo-based progress bar is going to work until your project has started running, you can't monitor the startup process.

The preload method you describe is if you need to preload graphics for an upcoming animation for example.

You can minimise the startup process by creating a fast-start projector and by only including the required xtras. See the link below

I would like to have a progress bar appear when loading images on my
portfolio website. I would also like to create my own customised progress
bar, that is more fitting with my website. I know about the publish setting
where you can choose to create a progress bar but do not know how to
implement it within a movie.

If anyone has any advice it would be much apreciated.

thanks
steve

One scheme is to have the initial 'loader' .dcr preload the main file to
local drive using preloadNetThing command, you can get percent loaded
info with periodic netEvent status calls (i forget that function name...)

[steve]

thanks for your help i will see if i can figure this out.

My client's site has some rather large PDF files that take a while to download.
I need some help creating a progress bar to indicate how far along the download
is. Or if I just used some kind of animated gif to 'pass the time' where does
it go in the code to make it show up on the page while the user is waiting for
the download to complete?

Hello everyone,

Hope this is a simple question!

I want to export my datagrid data to excel, so I just loop through every cell
to generate HTML string. But because the data amount is too large, it will
take tens of seconds to process it. So I want to give a client a progress bar
to indicate how much time left.

But the problem is the progress bar seems only update after all the process
finished, that is the application is too busy and looks like stopped during the
runtime. Can I make the progress bar keep updating and the process "export to
excel" run in the backgroud. Or can I have two threads to run two different
processes?

Thank you very much.

Hi,
Can I ask, how do you actually do the export. Do you generate an EXCEL file
and save it to the server, and then link to the file on the server, or do you
pass it directly to the client without writing to the server?

[cialeen]

Hi,

I used the navigateToURL(request, "_blank") to open a page on the server after
I generate all data to HTML string.

I tried to use ExternalInterface API to access Javascript in the wrapper page,
but it only works for Firefox not for IE. It kept saying that "trend" is
undefined. (which trend is the of in the embed object.) So I gave up but
actually this method is my preferred solution.

Any suggestions for the progress bar???

Thank you very much.

I created my own Progress Bar component, setting properties that will always
keep the bar moving, and then show/hide the component using event listeners and
handlers (see attached code).

CustomProgressBar.mxml:

<?xml version="1.0" encoding="utf-8"?>
<mx:Box xmlns:mx="http://www.adobe.com/2006/mxml"
creationComplete="setProgress();"
backgroundColor="white" borderStyle="solid" cornerRadius="10"
paddingLeft="10" paddingRight="10" paddingTop="10" paddingBottom="10">
<mx:Script>
<![CDATA[

[Bindable]
public var progressBarLabel:String = "Retrieving Data..."

public function setProgress():void
{
progressBar.setProgress(5, 10);
}

]]>
</mx:Script>

<mx:ProgressBar
id="progressBar"
mode="manual"
indeterminate="true"
label="{progressBarLabel}"
textAlign="center"
indeterminateMoveInterval="20"
minimum="1"
maximum="10" />
</mx:Box>

CustomCanvas.mxml:

<?xml version="1.0" encoding="utf-8"?>

// Handler for Creation Complete event
public function init():void

// Create a Progress Bar Component
customProgressBar = new CustomProgressBar();

customProgressBar.validateNow();

// Hide the Progress Bar Component
customProgressBar.visible = false;
customProgressBar.includeInLayout = false;

// Add the Progress Bar Component to this Component
this.addChild(customProgressBar);

this.addEventListener("dataRetrievalEnd", endProgressBar);
}

// Show the Progress Bar

// Set the coordinates of the Progress Bar Component to the center it over

customProgressBar.x = (this.width/2)-(customProgressBar.measuredWidth/2);

Thank you very much for your reply, Eric.

I tried your code but it didn't work for me.

My code is
private function openPage( pageFormat:String ):void
{
this.dispatchEvent( new Event( "dataRetrievalStart" ) );

if ( dataHtml == "" )
dataHtml = convertDataToHTMLDisplay();

this.dispatchEvent( new Event( "dataRetrievalEnd" ) );
}

The method "convertDataToHTMLDisplay" will do the actual converting job. When
run method "openPage", first dispatch an event to make progress bar visible,
and then go to the convertion, remove progress bar. But to the client's point
of view is the progress par never show up and application is stopped for a
while (actually busy for generating HTML).

If I remove the latst line :
this.dispatchEvent( new Event( "dataRetrievalEnd" ) );
then it looks like the progress bar will show up after the generation
finished. That's no use for me.

The thing I want to do is while the application is doing the HTML generation,
the progress bar can show the status at the same time.

Please help!
