AJAX :: Asynchronous Code For Checking Ports?

Nov 7, 2010

I have some code which connects to a port quickly and if it can connect then it turns the line in the gridview green, if it cant and times out then it turns the line red. This is great, the problem i have is that the page takes a long time to load (as it has to check each port first) and then if i want to check again if the port is up / down i have to manually refresh it which is not what im after.

[Code]....

The code is in a loop and cycles through the various ports in the DB, what i want to know is how i can write a loop that will going through each port without waiting for the last port to come back with a result

Secondly do this in some way that it will auto refresh every 30 or 60 seconds without having to refresh the whole page.

Add Web Reference Does Not Generate Asynchronous Proxy Code?

Jan 28, 2010

I am trying to add a web reference to an ASP.NET 2.0 application in Visual Studio 2008.However, the generated proxy classes do not include BeginXXXX and EndXXXX methods.Hcan I get these to be generated? Do I need to manually use wsdl.exe?(Incidentally in ASP.NET 3.5 apps, there is an option in the Add Service Reference box which lets me specify that Async methods should be generated. However, I am limited to ASP.NET 2.0 implementation).

Keep That Password Encrypted In Code While Checking It Against A Data Store?

Jan 18, 2011

Even with https enabled, you can write a password to the event log in code-behind. Any way to keep that password encrypted in code while you're checking it against a data store?

(using Login control)

(couldn't add comment to Andrew's answer, so I'm putting it here)
NTLM uses the username/password of the machine the user is logged into right? For this, I was thinking using ActiveDirectory on the server as the data store. It would have a diferrent un/pw than what the user is currently signed in to their machine as.

IIS - Different Ports To Run Several Websites Under One IP Address?

Nov 18, 2010

Setting ipaddress:80 as binding is standard. Setting ipaddress:87 (or any other number rather than 80) means another website can be accessed via the same IP, using port 87. When accessing this second site from the server itself (normally, not via localhost) it works fine. But on a remote client the browser complains that the server takes too long to respond and is not displaying the site.

IIS6 To Host Same Site To Different Ports?

Oct 26, 2011

IIS6 VS2008 .... I am trying to make a site that some folders will run on different ports of IIS but with the same site name.

So p.e. i would like mysite.com and mysite.com/hello to opetate on port 83 and mysite/otherport to operate(with any subfolders) on port 84.

Is this possible?I want to have 2 different membership databases on the same site so i'm thinkg either host a complete different site inside mysite/otherport or have multiple web.configs on the inner folders.The site is actually redirected to a server IIS so p.e. the site mysite.com is actually redirected to myserver.myiis.com:83

Visual Studio :: View In Browser Goes To Different Ports?

Jun 29, 2010

I have a solution CPortal created in Visual Studio 2010. It has two Projects (CPporal and Login). If I right click the Login project folder and select 'View in Browser' It opens in IE as http://localhost:4558/Login/. If I rightclick the CPortal folder and select 'View in Browser it opens as http://localhost:1807/CPortal/. Please note the change in port number.

I am facing problem because, after I get myself authorized on the Login, it is is supposed to redirect me to CPortal, which it does, but uses the same port number that Login opened with. i.e. It redirects me to http://localhost:4558/CPortal/ and gives 404 file not found error. How do I make Visual Studio 2010 to use the same port number for both (all) projects so that this problem does not occur.

AJAX :: Set A Textbox's Value Before A Asynchronous Postback?

Mar 16, 2010

Is there any way can let me set a textbox's value before the asynchronous postback. but I don't want to add a handler for a control which caused that asynchronous postback, because there are too much control can cause that. I want to know if there is a client event would be caused before the postback.

I tried the event initializeRequest of PageRequestManager to do this, but it did not work, it seems like the request has been generated when this event was executed, the value i set in this event for textbox did not be sent to server.

here is a page I used to test

HttpHandlers / Modules :: Using HttpWebRequest To Connect To Non Standard Ports?

Feb 4, 2010

I have an HttpHandler that runs the following code:

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(targetUri);
StreamReader stream = new StreamReader(webRequest.GetResponse().GetResponseStream()); [code]....

It works fine in my local machine for both, the default port 80 and the different 8090 but in my hosting it doesn't works for the 8090, returning "Unable to connect to the remote server" after few seconds.Anyone knows some workaround to call ports different than the 80?

AJAX :: Asynchronous Data Load In Dropdownlist?

Aug 20, 2010

first i'll describe my problem:

I have payment form with a clients dropdownlist that is populated from a database on form load with:

value field = clientIdtext field = nameId
<asp:DropDownList ID="selClients" runat="server">
</asp:DropDownList>

When user makes a payment, it's necessary to chose a client from selClients, and so i get the clientsId value and build my insert SQL query.

Until here, no problems.

The problem with my UI has started since i had a lot of clients been registered: My dropdownlist became huge and it's taking too much time to load it's contents on page load. Also the dropdownlist area is taking a large area from page screen.

So i tryied a solution with jquery autocomplete plug in. I put a textbox with autocomplete for client name and another hiddenfield to receive the clientId when user select a item.

That solves both problems:

No more large amout of data loaded on page loadThe dropdownlist doesn't take a large area from page screen
But it gave me another problem!

With a textbox, there is a possibility for wrong input client name. So if i don't have a valid clientId in hiddenfield, it will generate a database INSERT exception because it doesn't respect the client table constraint:

payment table REFERS client table

I'm trying to find kind of dropdownlist where the user can type text with autocomplete. Like this, the user will be able to select only data within the possibilities of the dropdownlist and i always will have a valid clientId.

AJAX :: ScriptManager Will Not Perform Asynchronous Postbacks?

Jul 14, 2010

I am trying to integrate ASP .Net AJAX into an existing application, but so far I am striking out.After significant digging, I found that for some reason, the ScriptManager was set so that SupportsPartialRendering is false, overriding EnablePartialRendering. From looking at the MSDN documentation, it seems to me that this should not be the case.The rules for determiningrSupportsPartialRendering are (from MSDN):The W3CDomVersion property value must be greater than or equal to 1.0.The EcmaScriptVersion property value must be greater than or equal to 1.0.The SupportsCallback property value must be set totrue.Using Firefox 3.6 and IE7+, these tests should have passed. W3CDomVersion = 1.0, EcmaScriptVersion=1.4, and SupportsCallback=true.n an effort to see if I could get around it by setting the value myself, I overrode the OnInit function in the code behind to explicitly set SupportsPartialRendering to true.his appeared to attempt to start an async postback, but failed with the javascript error "this._postBackSettings.async' is null or not an object" from within the ASP.Net AJAX scripts.

Also, I created a sample application outside of my existing project and got it working exactly as I wanted. When I copied and pasted all the code from the sample project and put it into the existing solution (aspx and code behind) it experienced the same issue. I know that it has something to do with the existing solution, but I am at the end of my rope as to what it could be.Other relevant information:he solution I am trying to integrate this into was at one time upgraded from ASP .Net 2.0 to 3.5.The controls which trigger the async postback are in a repeater and are being registered with ScriptManager.RegisterAsyncPostBackControl during prerender by looping over the bound items in the repeater. This occurs after the Repeater is databound. At the same time, triggers are dynamically added to the UpdatePanel. Code snippet (taken from OnPreRender):

[Code]....

I think the "_postBackSettings.async is null" error is something of a red-herring and is an indication that I am headed down a wormhole, so I am not considering heading down the path of forcing SupportsPartialRendering to true for now. Does anyone know what else could be turning it off in the first place? Or what else could be preventing partial rendering from functioning as expected?

AJAX :: Stop 2 Asynchronous Web Service Calls?

Nov 22, 2010

We have a custom Ajax checkbox control. In that control we set value (from inside the control) via a web service call (say WSCall1) to the business engine. There is also an event exposed on the OnClick of checkbox for the end user to have their custom code where the end user have their own web service call (say WSCall2). This event that end users will write is handled inside the ajax checkbox control on the "OnSuccess" of the internal web service call (i.e WSCall1) with an expectation that if WSCall1 succeeds, WSCall2 will get executed. This works fine with Firefox and Chrome but not in IE. In IE sometimes WSCall2 gets executed first and then WSCall1 -- actually there is no gurantee which web service gets called first. For WSCall1 we have used " Sys.Net.WebServiceProxy.invoke"

Is there a way we can make sure that WSCall2 gets only executed on the "OnSuccess" of WSCall1? Isn't the OnSuceess supposed to be executed when the WSCall1 thread returns?

AJAX :: Webforms And Master Page Asynchronous Postback?

May 18, 2010

I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.

AJAX :: Asynchronous Web Services, JQuery Or .NET (BeginInvoke) Calls?

Sep 24, 2010

I have been moving my application to be more AJAX-based. Currently I have a web service call where I use jQuery to gather some textbox (string) and checkbox (boolean) results and pass it to a web service. Everything works really well, the response time is super quick. The only downside that I can see to this is

1) you need to use jQuery, which will add to the user's download time - this doesn't really affect my application too much because I am using jQuery throughout the site

2) users can see the code and potentially try to hack the web service because they know where it is

I am most concerned with #2. I've been reading a lot about .NET web service calls, using IAsyncResult,

http://msdn.microsoft.com/en-us/library/2e08f6yc.aspx, and I am beginning to understand the 4 methods available in this article. However, is there extra bloat using this way compared to the jQuery web service call?If there isn't that much bloat or lag time using this method, I'd like to convert my application. Which one of these 4 methods is best in a scenario where I am just returning a small string value? The 4 methods in the article are to wait for EndInvoke itself, which from what I read is not recommended because this may block the first thread; and this should not be used on a service that affects the UI.Create a WaitHandle to wait for the 'OK' before EndInvoke is called Poll the IAsyncResult for .IsCompleted, using sleep() and a Do While until IAsyncResult.IsCompleted is true, then call EndInvoke Pass a delegate function to BeginInvoke to be called once the operation is complete.
