I am trying to clear an uploadify queue from a .net method by this:
ScriptManager.RegisterStartupScript(Page, Page.GetType(), Guid.NewGuid().ToString(), "javascript:$('#" + file_upload_reply.ClientID + "').uploadifyCancel('*')", True)
but it does not clear the queue. Is it possible to clear the queue using the command uploadifyCancel?
Thanks for any pointers.
Library ScriptManager:
Manages ASP.NET AJAX script libraries and script files, partial-page
rendering, and client proxy class generation for Web and application
services.
Use ClientScript:
Such as in Page_Load:
protected void Page_Load(object sender, EventArgs e)
{
ClientScriptManager cs = Page.ClientScript;
if (!cs.IsStartupScriptRegistered("cancel"))
cs.RegisterStartupScript(GetType(), "cancel", "javascript:$('#aa').uploadifyCancel('*')", true);
}

I am trying to develop a web-socket server app for my UWP Windows 10 App.
This is my code:
class Server
{
public async void Start()
{
MessageWebSocket webSock = new MessageWebSocket();
//In this case we will be sending/receiving a string so we need to set the MessageType to Utf8.
webSock.Control.MessageType = SocketMessageType.Utf8;
//Add the MessageReceived event handler.
webSock.MessageReceived += WebSock_MessageReceived;
//Add the Closed event handler.
webSock.Closed += WebSock_Closed;
Uri serverUri = new Uri("ws://127.0.0.1/motion");
try
{
//Connect to the server.
await webSock.ConnectAsync(serverUri);
//Send a message to the server.
await WebSock_SendMessage(webSock, "Hello, world!");
}
catch (Exception ex)
{
//Add code here to handle any exceptions
}
}
//The MessageReceived event handler.
private void WebSock_MessageReceived(MessageWebSocket sender, MessageWebSocketMessageReceivedEventArgs args)
{
DataReader messageReader = args.GetDataReader();
messageReader.UnicodeEncoding = Windows.Storage.Streams.UnicodeEncoding.Utf8;
string messageString = messageReader.ReadString(messageReader.UnconsumedBufferLength);
//Add code here to do something with the string that is received.
}
//The Closed event handler
private void WebSock_Closed(IWebSocket sender, WebSocketClosedEventArgs args)
{
//Add code here to do something when the connection is closed locally or by the server
}
//Send a message to the server.
private async Task WebSock_SendMessage(MessageWebSocket webSock, string message)
{
DataWriter messageWriter = new DataWriter(webSock.OutputStream);
messageWriter.WriteString(message);
await messageWriter.StoreAsync();
}
}
It errors here:
await webSock.ConnectAsync(serverUri);
with this error:
Not found (404). (Exception from HRESULT: 0x80190194)
I don't have any personal experience with it, but you might want to give IotWeb HTTP Server a try. It seems to be a portable embedded HTTP and web socket server that also supports UWP and can be run inside Windows Store and Windows 10 IoT Core applications.
Judging from its repository, it's rather new and not exactly mature, nor does it have a lot of documentations or samples available. There's a NuGet package available, though.
Unfortunately I didn't manage to find any other alternative yet.
The code
await webSock.ConnectAsync(serverUri);
Is try to connect to existing server at ws://127.0.0.1/motion, Not to deploy a server on this address.
You can look for ways to build a c# WebSocket server at the follwing links:
https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_server
http://www.codeproject.com/Articles/57060/Web-Socket-Server
I want to create a simple login functionality in WP7 app using remote MySQL database using PHP as back-end. I have never used this in C#, so I don't know how to do this.
You can use WebClient or HttpWebRequest class to make a web request and get the response.
Here is a sample code on how to make a request and get response
WebClient client = new WebClient();
client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);
client.DownloadStringAsync(new Uri("http://someurl", UriKind.Absolute));
And the asynchronous response handler is here
void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
var response= e.Result; // Response obtained from the web service
}
The above example works for any web service(it may be PHP or jsp or asp etc).
All that you need to do is to make a proper request and handling the response
I m my application I want to use Webbrowser which will be using Wifi,after the Webbrower opens the the link (task.URL) ,I want to check what is the response like whether the linked got opened or it failed.How do I do that means get the response ?

Usually, to catch this use NavigationFailed event as follow:
void WebPage_Loaded(object sender, RoutedEventArgs e)
{
this.webHome.Navigate(new Uri(www,UriKind.Absolute));
this.webHome.NavigationFailed += webHome_NavigationFailed;
}
void webHome_NavigationFailed(object sender, System.Windows.Navigation.NavigationFailedEventArgs e)
{
this.webHome.NavigateToString("No web page available.");
}
i want to get the time schedule on
http://www.21cineplex.com/playnow/sherlock-holmes-a-game-of-shadows,2709.htm
first,
i have tried using webclient with htmlAgilityPack and get to the table id = "table-theater" but appearently the html generated from java script so the table innetHTML is empty.
public void LoadMovieShowTime(string MovieLink)
{
WebClient MovieShowTimeclient = new WebClient();
MovieShowTimeclient.DownloadStringAsync(new Uri(MovieLink));
MovieShowTimeclient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(MovieShowTimeclient_DownloadStringCompleted);
}
void MovieShowTimeclient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(e.Result);
var node = doc.DocumentNode.Descendants("div").First()
.Elements("div").Skip(1).First()
.Elements("div").Skip(1).First()
.Element("div")
.Elements("table").FirstOrDefault(table => table.Attributes["class"].Value == "table-theater");
}
Is it possible to get the data using webclient on windows phone? or is there any pssible way to get it using another method?
second,
i have tried to get the time schedule from mobile site which is
http://m.21cineplex.com/gui.list_schedule?sid=&movie_id=11SHGO&find_by=1&order=1
but the return ask me to enable cookies. im new to this, i find that there is a way to extend webclien ability by overriding the webRequest cookies, but cant find any reference how to use it.
thanks, for any reply and help :)
Just because the table is generated in JavaScript does not mean the WebBrowser control will not render it. Ensure that IsScriptEnabled is set to true, this will ensure that the JavaScript that renders the table is executed. You can then 'scrape' the results.
When i try to get uploaded filename from generic handler (upload.ashx) using session its ok, no problem. I can also use webmethod on samepage and uploadify works great, but Session["fileName"] is getting null. Is there anything wrong on my code? Do i only need to use generic handler to get filename?
[WebMethod(EnableSession = true)]
public void LoadPicture(HttpContext context)
{
try
{
HttpPostedFile file = context.Request.Files["Filedata"];
context.Session["fileName"] = file.FileName;
....................Some resize and save image codes.........
context.Response.Write("1");
}
catch (Exception ex)
{
context.Response.Write("0");
}
}
protected void Button1_Click(object sender, EventArgs e)
{
using (_modelService = new ModelService())
{
ModelEntity _models = new ModelEntity();
......some codes....
_models.modelphoto = Session["fileName"].ToString();
_modelService.ModelAdd(_models);
}
}
Uploadify uses Flash. Flash doesn't send cookies. In ASP.NET sessions are tracked by cookies. So, no session with uploadify, sorry.
