[flexcoders] Problem with ColumnChart within a repeater

2005-12-01 Thread jrab2999

Hello,

I am trying to use a ColumnChart within a Repeater. Sadly the charts
are always empty. If I copy and paste the chart below the repeater,
the chart is displayed with valid vlaues of the last repeat. The
bindings seem to be right. So why the charts are empty if it's inside
the repeater? Is it a bug? I am using Flex 1.5.

Source:

mx:Repeater id=panel
dataProvider={dataService.result.survey.bereich}

...

mx:VBox borderStyle=none marginTop=0 marginBottom=4
marginLeft=0 marginRight=7 width=314 height=100%
mx:ColumnChart type=stacked columnWidthRatio=.7 marginLeft=0
height=100% width=100% marginRight=0
dataProvider={panel.currentItem.reihe} showDataTips=false
clipContent=false
mx:horizontalAxis
 mx:CategoryAxis dataProvider={panel.currentItem.reihe}
categoryField=text/
/mx:horizontalAxis
mx:series
 mx:Array
  mx:ColumnSeries xField=text yField=wert styleName=seriesStyle
  /mx:ColumnSeries
 /mx:Array
/mx:series
/mx:ColumnChart
/mx:VBox

...
/mx:Repeater

Thank you for any kind of help!

Re: [flexcoders] Socket (not XMLSocket) Issue

2005-12-01 Thread Ralf Rottmann

Title: Re: [flexcoders] Socket (not XMLSocket) Issue








Darron,

Thanks so much. Sometimes it's better to know something cannot be done than to search for a solution hours and hours.

Two remaining questions:

1. What do you think about using something like a sequence number? Client Requests increment a sequence number and server returns it. The sequence number could then be used as a literal index in a collection.

2. There is still one part I don't get: Suppose I send my command to the server. Right after that I start a for loop incrementing to like 10 doing nothing in the loop body. I just want to kind of sleep. My idea was that sometime while the for loop still executes, the response is retrieved, so the OnDataReceived event should be fired (by the Socket) even if I am still in the for loop. Isn't this the idea of asynchronous events? However to me it appears that the event does not get fired while I'm in the for loop. Instead the event (and the attached Handler) is called right after the loop exits. Why?

Thanks in advance
Ralf

Welcome to the world of asynchronous socket programming. In short, you
can't do what you want to do in the manner in which you have it coded
above. There is no way to make the Flash Player block until the socket
returns a value, so you're only choice is to move everything into event
handlers.

Essentially, this was the biggest hurdle for me in developing FlashVNC.
I was so used to doing thing synchronously that having to deal with
event handlers and callbacks for socket data threw a monkey wrench into
my master plan. The main issues I ran into:

1. Not sure which socket write the onSocketData event handler is
triggered by (if any).
2. Not enough data in the socket to finish processing (i.e. you need to
call 4 readBytes but only 3 bytes are available, so you get an EOFError
when trying to read the 4th byte and your program dies).

To fix #1, a simple solution is to use a state variable:

// send the login command
state = SENT_LOGIN;
SendCommand( login name );

// event handler
private function onSocketData( pe:ProgressEvent ):Void {
 switch ( state ) {
 // recevied data back after the login was sent, handle the response
 case SENT_LOGIN: processLoginResponse( pe ); break;
 case OTHER_STATE: processSomeOtherState( pe ); break;
 }
}

Somewhere down the line, update the state and write some more data in
the socket so when data is received as a response you can call the
appropriate handler in the switch. This isn't quite100% how I'd
implement it, but you get the idea.

#2 above is potentially a LOT harder to handle. The gist of it is you
need to know how many bytes of data you need in the socket before
starting to read the data in the socket. That is, the first line in the
method body should be:

// method called from within onSocketData
private function processLoginResponse( pe:ProgressEvent ):Void {
 if ( socket.bytesAvailable = BYTES_NEEDED ) {
 // have enough data, ok to process
 } // else not enough data, so just wait for onSocketData to be
called again when more data arrives
}

The trick is knowing how many bytes are needed. After talking with
Spike about this - the best thing you can do is send the number of bytes
in the response as the first element in the response. That way the
client can read how many bytes the server sent, see how many bytes are
in the socket, and only process if all of the data has reached the client.

If you want an example of an application built with asynchronous
sockets, I recommend purchasing IFBIN's Flex By Example and looking at
the FlashVNC source code.

Also, Ely and Sho at Macromedia have some ideas on how to write easier
to read code for dealing with asynchronous events. Maybe they'll
contribute to this thread?

[flexcoders] showing values inside datagrid when click on button outside

2005-12-01 Thread sandip_patil01


Hi All,


I have data grid populated with records from DB as,
mx:DataGrid id=dGrid dataProvider={lglDocLst}
  mx:columns
  mx:Array
mx:DataGridColumn headerText=Item Name 
columnName=att_Name /
/mx:Array
  /mx:columns
/mx:DataGrid

where lglDocLst is values returned  from my Java class.
This works fine.In my datagrid its printing 2 values of att_Name.

Now I have a button outside datagrid as,
mx:Button label=Show click=showAlert() /

when I click on this button I am printing alert as

function showAlert(){ 
  mx.controls.Alert.show(MyValue +lglDocLst.att_Name);
   }

But this function printing undefined.
any suggestions will be appreciable.

Thx,
sandip p

[flexcoders] LabelFunction problem with DG built dynamically

2005-12-01 Thread Sreejith Unnikrishnan







I have a datagrid that is built
dynamically via AS.
I add columns to the datagrid 

   var
column:DataGridColumn = new DataGridColumn("Apples");
   column.headerText = "Apples";
   column.columnName = "apples";
   column.labelFunction = formatApples;

The labelFunction does not seem to work. What is the
right way to assign labelFunction.

Regards
Sree

[flexcoders] Re: Rich Internet Application (HaloGreen) Stencil for Microsoft Visio 2002

2005-12-01 Thread Darren Houle

Where exactly did I make a false pretense of free stuff?  Sorry if 
it came across like that, but there was no intention to deceive.

I actually had it set at less but Nimer suggested raising it to $25 
after using it.  I split the difference and went $20 (it did take me 
three weeks to develop after all.)  Believe me, if you're a Flash 
forms or Flex developer and you need to make static mockups this is 
awesome.  Not 100% perfect, but very complete and extremely useful.  
Actually don't believe me, wait a while to see what the feedback is 
for the stencil and then decide for yourself.

Thanks!
Darren

[flexcoders] Re: Rich Internet Application (HaloGreen) Stencil for Microsoft Visio 2002

2005-12-01 Thread Darren Houle

Dear WTF,

Not sure where you get the linking under false pretense of free 
stuff because I never said it was free, just pointed to more 
information.  I'm sorry you misunderstood.  No secrets here, it's 20 
bucks and includes a free update when the new Flex 2.0 object masters 
are added to the stencil. Considering it took me over three weeks to 
develop and it's extremely useful I think that's very reasonable.  I 
created it for my own use because I wanted an RIA stencil for Visio 
and there wasn't one out there already. Contacted Mike Nimer to see 
if he knew of one out there and he said no, but that it would be a 
cool thing, so... I made one.  After using it he suggested I sell it 
for more than 20... I thought I'd keep it low, so... there you are. 
It has worked quite well for me and based on the number of downloads 
from just this morning I'm guessing others are thinking it's worth 
the 20 bucks too.  Hopefully you will too once you get your copy :-)

Thanks!
Darren

Re: [flexcoders] gateway-config.xml configuration file description in Flex 1.5

2005-12-01 Thread Mykola Paliyenko

Ok Matt
What excectly I need is following:
1. Create my own adapter (don't ask me why I just need it),
2. Configure it with one string property, some parameter.
It is a common way for Filters, Servlets etc but seems to be impossible
for configuring adapters. If it is not impossible I'd like to create a
feature request for Macromedia to implement it since it makes sence :).
