I'm developing chat application. I use flash as front end and asp.net back-end. My question is: can my asp.net web app send data to flash app in browser without post back ?actually it mean asp.net push data to flash client. I don't know much about flash or siverlight, dose flash support to do that ? or other way help me connect direct from server to browser without using post back or Jabber ?
View 4 RepliesI'm transforming lotus note application to ASP.NET.In lotus note, we can pass the application(data) from staff to his/her manager for approval.The staff can also check status of his/her data whether the manager is opening it, approved it or not.This process can be done in real time. I mean on the staff screen he/she will see status is changing from data sent --> manager is opening --> manager accepted or manager rejected it.In the same time, if other staffs try to track this application(data) they will see the same screen with the first staff.ow, in asp.net, i'm thinking of sending data from staff to manager directly. I don't want manager's web browser need to do polling for every xx millisecond. I'm not quite too sure it can be done or not in asp.net because i'm not the WEB guy.After doing a research for a while, i found that comet may help me on that but it seems pretty hard. And I don't know it is suitable for my problem or not or someone may guide me a better idea on this.

In one web page we use a flash upload control but becouse a flash bug in the upload event the session is lost as its posted back with a new session.
We have tought of using a table with ip and old session id or a query string with the old session id in order to reassing it in the uploaded event...
Knowing the old session id how can i reassign it to the client? (In C#)
IIS 6.0 hosting ASP.NET 3.5. From the Visual Studio 2008 aspx code behind (aspx.cs) running on the server I need to determine if Silverlight is installed on the client and if so which version. I know from Java on the client this can be done. That is not what I need. I know I can put in a control that will render if Silverlight is installed. That is not what I need.
View 3 Repliesi am a php developer, not knowing much about silverlight, i am working on a project which needs to process request on client browser, like post httprequests and process them, its a auto directory submitter, can it be done in silverlight application?
i want the user to open the silverlight application, which will submit the post request from client side, and also process for success and failure. is it possible?
I'm having trouble exposing a method to a silverlight client from a WCF service although I can expose properties.
My WCF service has a LoadDeal method which returns a Deal object
public Deal LoadDeal(int dealerId)
{
Deal d = new Deal();
d.LoadDeal(dealerId);
return d;
[Code]....
This works fine and the Refernce property can be accessed from the silverlight client.
But when I try to expose a method such as the CancelEdit method below, I can't find a way to expose this method to the silverlight client:
public void CancelEdit()
{
//Add logic to cancel changes here.
}
I've tried adding the DataMember annotation but the compiler complains. I've re-compiled without an annotation and then updated the service reference but nothing seems to be working.

View 1 RepliesI have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?
View 8 RepliesI'm making tests with ASP.NET HttpHandler for download a file writting directly on the response stream, and I'm not pretty sure about the way I'm doing it. This is a example method, in the future the file could be stored in a BLOB in the database:
public void GetFile(HttpResponse response)
{
String fileName = "example.iso";
response.ClearHeaders();
response.ClearContent();
response.ContentType = "application/octet-stream";
response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);
using (FileStream fs = new FileStream(Path.Combine(HttpContext.Current.Server.MapPath("~/App_Data"), fileName), FileMode.Open))
{
Byte[] buffer = new Byte[4096];
Int32 readed = 0;
while ((readed = fs.Read(buffer, 0, buffer.Length)) > 0)
{
response.OutputStream.Write(buffer, 0, readed);
response.Flush();
}
}
}
When I open the url with the browser, appears the "Save File" dialog... but it seems like the server has started already to push data into the stream before I click "Save", is that normal? If I remove the line"response.Flush()", when I open the url with the browser, ... I see how the web server is pushing data but the "Save File" dialog doesn't come up, (or at least not in a reasonable time fashion) why?
When I open the url with a WebRequest object, I see that the HttpResponse.ContentLength is "-1", although I can read the stream and get the file. What is the meaning of -1? When is HttpResponse.ContentLength going to show the length of the response? For example, I have a method that retrieves a big xml compresed with deflate as a binary stream, but in that case... when I access it with a WebRequest, in the HttpResponse I can actually see the ContentLength with the length of the stream, why? What is the optimal length for the Byte[] array that I use as buffer for optimal performance in a web server? I've read that is between 4K and 8K... but which factors should I consider to make the correct decision. Does this method bloat the IIS or client memory usage? or is it actually buffering the transference correctly?
I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:

View 10 RepliesI have a response object which I want to convert to Json, but somehow I can't, propably beacuse of I cannot the framework too well. I'm trying to convert a anonymous object to json but somehow it doesn't go so well. I would preferably do it in JSON than just make a text/plain result. In my controller: ViewData["json"] = new { Ok = false }; In my view: <%: ViewData["json"] %>
In my js-code (ajax-callback) I get back the following: { Ok = False } Which ain't what I am excepting. I want the { ok : false } or else js doesn't recognize the property in the object as a boolean. Or are there some better way to push out json-data? EDIT I did a method in my controller with a JsonResult instead of Actionresult.
var obj = new
{
Ok = false,
Message = ""
};
return Json(obj);
And that's the object I'm pushing out. And like this in js: {"Ok":true,"Message":""} C# 4.0 and Javascript goes along so well
I want to create a flash swf file that will store a token in Local Shared Object. What do I need to do to read that token and look it up in the database on the back end? Is this possible at all? here is a possible scenario:
User visits my web page. A token is generated on the server and stored in the database. Token is then saved in LSO. User leaves the site (maybe shuts down his computer) and comes back later. Token is read, located in the database and the user is recognized (lets say that token is a foreign key that links to other user data stored in the db). I researched this for quite a while and all I find is that flash can use LSO to store read data for flash movie. Does this mean that the data can not be accessed by the server?
