Re: [flexcoders] Re: Flex and .NET
Hi Steve, The dataset which I am using in my Flex app is being edited, with some records added or deleted or filtered. As I am doing this in the Flex application, the backend service (web service) does not know which have been modified, thus, I need to send back the current data I have in the Flex application. By the way, some updates on this. I tried to send the ArrayCollection as it is in .NET and I am getting the same as an ArrayList, which contains XML document tags. The only beef with this is that there is no actual tag for the field (column), so I have no idea which column to actually map back to the dataset. I am going to field portions of the data returned back tomorrow, as my codes are all in my office machine. Thanks and regards, Angelo From: valdhor valdhorli...@embarqmail.com To: flexcoders@yahoogroups.com Sent: Tuesday, 9 June, 2009 21:31:56 Subject: [flexcoders] Re: Flex and .NET I don't understand why you would send the entire data set back to your .NET backend via the web service. The backend has already generated the data to be sent and the backend is what generates the report via Crystal Reports. I would have thought the best way was to send the query back to the back end, get it to do the data lookup again and pass the data into Crystal Reports.

As of now, I actually prefer to utilize what I know on .NET and what I am learning on Flex. Adding another utility (Web Orb) in my learning process may complicate things a bit. I might consult this later if I feel that the needs for is getting tremendous. Anyway, I am actually able to generate the report from what I am currently doing (no error encountered) , where the ArrayCollection I am parsing into a delimited string, passing the string to the webservice call, and letting the webservice de-serialize the string to populate a Crystal report document which I subsequentlt display in another browser window which I call from the Flex application. I mentioned that I did not feel it is the BEST way because I am literally storing all datagrid (report) information in a string variable. Assuming for example that the data displayed in the datagrid is quite huge, then creating the delimited string would take some time and additional processing time could also be consumbed by the back end web service to parse the string and populate the report. As of now, this is what the application does. 1. Flex App calls a webservice to retrieve data. 2. WebService responds by sending back a dataset which is returned as a string (via Dataset.GetXML method of .NET). 3. Flex App gets the service response, converts the string into an XML. 4. Flex App converts the XML data into an ArrayCollection which is bound to the datagrid. * Please note that I used array collection here for the search/filter functionality of the datagrid. 5. When generating print out of the data displayed in the datagrid, Flex would then serialize the ArrayCollection into a delimited string and send it to the web service. 6. Web Service would then de-serialize (or parse) the string, populate a .NET dataset which is the datasource for the Crystal report. 7. Crystal report is bound and PDF report is generated. 8. Flex displays via external javascript call the PDF report generated. Is there a better way for the ArrayCollection to be sent to the webservice, the webservice in turn would just convert it to dataset and the dataset is immediately bound to the Crystal report? Thanks.

I tried initially to pass an XML delimmited string, but .NET seems to read XML differently( ?) from Flex. I'd say XML would be a good way of doing it. What kind of errors are you getting, and how are you making the web service call? The other option is to use AMF, a native messaging format for Flash/Flex. This I believe would save you the effort of serializing and deserializing - it does it for you, among other things. http://www.themidni ghtcoders. com/products/ weborb-for- net/overview. html

Thanks Ben,
Changing the data type to Number didn't help either. I'll have a look at
Darron's solution ...

Hi Robin,
I have good news :), both of these issues should go away by setting a
single attribute on your WebService object. Try setting
makeObjectsBindable = false. This will cause Flex to deserialize your
ws responses into regular Object and Array instances instead of
ObjectProxy and ArrayCollection instances.

Hi Robin,
I have good news :), both of these issues should go away by setting a
single attribute on your WebService object. Try setting
makeObjectsBindable = false. This will cause Flex to deserialize your
ws responses into regular Object and Array instances instead of
ObjectProxy and ArrayCollection instances.
HTH,
Ben

Hi Sam,
Remoting is definitely a good alternative and would probably make things
a bit easier. I'm not programming the .net side of things though and the
guys who are working on the backend are not too keen on using a
technology which is not established standards yet.
I had a look at Fluorine earlier this year and it looks very good
though
Cheers
Robin

It sounds like you may be looking for a Remoting Gateway which uses AMF
rather than Web Services and has the ability to translate .NET - AS
Objects.
I've got articles written on two different options, Fluorine and WebOrb.

Re: [flexcoders] Re: Flex vs. .Net for RIA database apps; new to both
Actually flash remoting is part of Flex, when you use RemoteObject, you are using remoting.The thing is that currently (in F2B3), there are only server-side remoting gateway for Coldfusion (which support AMF3 - which also means, if you use RemoteObject in F2B3, your backend must be Coldfusion with updated adaptor) and FDS (which support Java only). So If you want to use Flex2 with .NET and remoting today, you can't use RemoteObject out of the box, you will have to maually create NetConnection instance and connect/call remote method.this is the product page from adobe: http://www.adobe.com/products/flashremoting/Fluorine is an open-source version of it, but just like the nature of most open source projects, stability and continuous development is always a consideration, when we have enough budget on the project, we will go with official product (at least we know whom to go to when things go wrong :-) ) On 6/12/06, michaellisten [EMAIL PROTECTED] wrote: What software is needed in order to use flash remoting?
