  • WCF Duplex Interaction with Web Server

    - by Mark Struzinski
    Here is my scenario, and it is causing us a considerable amount of grief at the moment: We have a vendor web service which provides base level telephony functionality. This service has a SOAP api, which we are leveraging to build up a custom UI that is integrated into our in house web apps. The api functions on 2 levels. You make standard client calls into the service to initiate actions, such as Login, Place Call, Hang Up, etc. On a different thread, the service sends events back to the client to alert the user of things that are occurring on the system (agent successfully logged in, call was disconnected, etc). I implemented a WCF service to sit between the web server and the vendor service. This WCF service operates in duplex mode, establishing a 2 way connection with the web server. The web server makes outbound calls to the WCF service, which routes them to the vendor's web service. Events are received back to the WCF service, which passes them onto the web server via a callback channel on the WCF client. As events are received on the web server, they are placed into a hash table with the user's name as the key, and a .NET queue as the value to hold the event. Each event is enqueued to the agent who owns it. On a 2 second interval, the web page polls the web server via an ajax request to get new events for the logged in user. It hits the hash table for the user key, dequeues any events that are present, and serializes them back up to the web page. From there, they are processed in order and appropriate messages are displayed to the user. This implementation performs well in a single user scenario. The second I put more than 1 user on the system, I start getting frequent timeouts with the following CommunicationException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond We are running Windows Server 2008 R2 both servers. Both the web app and WCF service are running on .NET 3.5. The WCF service is running under the net.tcp protocol in duplex mode. The web app is ASP.NET MVC 2. Has anyone dealt with anything like this scenario? Is there a more efficient way (or a widely accepted pattern) to implement this?

  • How to detect the vertical scrollbar in a DataGridView control

    - by Billy
    Using winforms in vs2008. I have a DataGridView and I would like to detect when the vertical scroll bar is visible. What event should I register for? I am adding the summing the each cell value in the last column of the grid and displaying that value in a textbox at the bottom of the DataGridView. I would like this textbox to stay lined up with the cell values (I have made them right aligned since it is $$ values) even after the scroll bar is present.

  • How to restrict rightBarButtonItem size in UINavigationBar ?

    - by lefakir
    I create a rightBarButtonItem with this method : - (UIBarButtonItem *)customBarButtonWithSelector:(SEL)callback { UIButton *customButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; customButton.bounds = CGRectMake(0, 0, 30.0f, 30.0f); return [[[UIBarButtonItem alloc] initWithCustomView:customButton] autorelease]; } At execution time the selector is fired when the bar is touched outside the button (near the middle). Is there a way to restrict the event responder in the defined bounds or in a acceptable range ?

  • Control.IsAccessible

    - by Gerhard
    I need to check if a c# WinForm Window (FORM Class) has been initialized and waiting for user events. But I could not find out how to manage that. Therefore I had the idea to set the Control.IsAccessible Flag of the Form to true, within the OnLoad Event of the Windows Form. My question is now, what is the Control.IsAccessible Flag origin intended for? Or is there an other solution to check if the Winform is initialized. Thanks for your help

  • Why does Visual Studio sometimes add a number when creating page events in codebehinds?

    - by Kevin Pang
    When writing up a codebehind in Visual Studio for ASP.NET web forms applications, I often use the dropdowns at the top of the window to autogenerate page event handlers (e.g. Page_Load, Page_PreRender). I've noticed that sometimes Visual Studio likes to add numbers to these function names like "Page_Load1" or "Page_PreRender2". Programatically speaking, this has no effect on the code. But stylistically, I find it a bit ugly. Is there any way to get rid of this behavior?

  • Gui's with Win32 API

    - by user146780
    I'm wondering what the correct way of creating Gui's in with Win32 API. Right now I just call the CreateWindowEx in my WM_CREATE event, but I don't think this is the right way to do it. Just as an example, what would be the correct way of adding a 100x20 EditField and getting text from it? Would you create it on WM_Create then use GetText()? Thanks

  • CSS Calendar Display

    - by Steven
    I created my own custom date picker consisting of an ASP TextBox, Button, and Calendar complete with CSS styles, javascript code, and event handling vb code. I want to use this date picker multiple times on my form. I know the wrong way to do this would be to copy all the code and just adjust each name accordingly. How can I put those controls, styles, and code into a single entity?

  • How to know a device's name from its device ID in OS X?

    - by yangumi
    Hi all, I'm writing a program in OS X that receives click events from a mouse and a touchpad. When the user clicks at somewhere, the OS sends the device ID, which is just an int, and the position of the cursor to my callback function. I want to know if the click event comes from mouse or touchpad. So, how can I know the device's name from its device ID? Thank you! (I'm sorry for my poor English.)

  • Java mouse motion anywhere on screen

    - by Dave
    I'm sure this is possible but all my searching is coming up blank. In Java is it possible to register for a mouse motion event outside of a Java app? So if the mouse pointer moves anywhere on the screen I get a call back. An approximation is possible with polling MouseInfo.getPointerInfo but there must be a better way. Thanks

    Is it possible to disallow free text entry in the JQuery UI autocomplete widget? eg I only want the user to be allowed to select from the list of items that are presented in the autocomplete list, and dont want them to be able to write some random text.

  • Booking form works but does not give feedback

    - by Naim
    I have a form where people can book seats for a given event. It's actually a WordPress plugin. When someone sends his booking, email notifications are sent properly and the event booking status is updated accordingly. The issue is that the booking form does not give any feedback whatsoever. Once you hit "book now", the graphic keeps loading and no feedback is ever displayed like for instance "booking sent successfully" or "there are errors in your form", even though the booking is saved correctly with both sides notified by email. I guess it's a JavaScript issue,Firebug console is not showing any error... So here is the code source of the booking form : Also please experience the issue live Here username: tester password: testsa Thanks! $('#em-booking-form').submit( function(e){ e.preventDefault(); var em_booking_doing_ajax = false; $.ajax({ url: EM.bookingajaxurl, data:$('#em-booking-form').serializeArray(), dataType: 'jsonp', type:'post', beforeSend: function(formData, jqForm, options) { if(em_booking_doing_ajax){ alert(EM.bookingInProgress); return false; } em_booking_doing_ajax = true; $('.em-booking-message').remove(); $('#em-booking').append('<div id="em-loading"></div>'); }, success : function(response, statusText, xhr, $form) { $('#em-loading').remove(); $('.em-booking-message').remove(); $('.em-booking-message').remove(); //show error or success message if(response.result){ $('<div class="em-booking-message-success em-booking-message">'+response.message+'</div>').insertBefore('#em-booking-form'); $('#em-booking-form').hide(); $('.em-booking-login').hide(); $(document).trigger('em_booking_success', [response]); }else{ if( response.errors != null ){ if( $.isArray(response.errors) && response.errors.length > 0 ){ var error_msg; response.errors.each(function(i, el){ error_msg = error_msg + el; }); $('<div class="em-booking-message-error em-booking-message">'+error_msg.errors+'</div>').insertBefore('#em-booking-form'); }else{ $('<div class="em-booking-message-error em-booking-message">'+response.errors+'</div>').insertBefore('#em-booking-form'); } }else{ $('<div class="em-booking-message-error em-booking-message">'+response.message+'</div>').insertBefore('#em-booking-form'); } } $('html, body').animate({ scrollTop: $("#em-booking").first().offset().top - 50 }); //sends user back to top of form //run extra actions after showing the message here if( response.gateway != null ){ $(document).trigger('em_booking_gateway_add_'+response.gateway, [response]); } if( !response.result && typeof Recaptcha != 'undefined'){ Recaptcha.reload(); } }, complete : function(){ em_booking_doing_ajax = false; $('#em-loading').remove(); } }); return false; });
