  • Should I ignore the occasional Invalid viewstate error?

    - by Richard Ev
    Every now and then (once every day or so) we're seeing the following types of errors in our logs for an ASP.NET 3.5 application Invalid viewstate Invalid postback or callback argument Are these something that "just happens" from time-to-time with an ASP.NET application? Would anyone recommend we spend a lot of time trying to diagnose what's causing the issues?

  • Are functions declared before or after calling them?

    - by DMan
    I've made this a community wiki... Okay, I was looking through someone's code one day and I was annoyed how they declared all their functions first and then later called them below. I guess I'm use to Visual Studio's automatically generated functions, that are made after you call them- and I was wondering, which way do you prefer? Or is there a standard on these kind of things?

  • How do I add NSDecimalNumbers?

    - by Terry B
    OK this may be the dumb question of the day, but supposing I have a class with : NSDecimalNumber *numOne = [NSDecimalNumber numberWithFloat:1.0]; NSDecimalNumber *numTwo = [NSDecimalNumber numberWithFloat:2.0]; NSDecimalNumber *numThree = [NSDecimalNumber numberWithFloat:3.0]; Why can't I have a function that adds those numbers: - (NSDecimalNumber *)addThem { return (self.numOne + self.numTwo + self.numThree); } I apologize in advance for being an idiot, and thanks!

  • intercepting http traffic to/from Google Chrome

    - by anjanb
    I use Fiddler for intercepting HTTP traffic when using IE or Firefox. Now that I'm using chrome for most of my day, I would like to be able to see the http traffic using something like Fiddler. What do chrome developers use ? I prefer something automatic like Fiddler but something that needs config, etc would also help. P.S : I'm on windows vista 64-bit HOME PREMIUM, if that's important.

  • How to change the request IP in HttpWebRequest?

    - by holiveira
    I'm developing a website that will connect to a credit card processing gateway webservice. For security purposes this webservice accepts requests only from IP addresses that were previously informed to them. Since I'm developing locally, my IP changes almost every day. Is there a way for me to change the IP address of a HttpWebRequest so that I can test the Webservice calls locally? This webservice is accessed through a https address and the methods must be sent via POST.

  • SQL Insert into ... values ( SELECT ... FROM ... )

    - by Shadow_x99
    I am trying to insert into a table using the input from another table. Although this is entirely feasible for many database engines, I always seem to struggle to remember the correct syntax for the SQL-Engine of the day (MySQL, Oracle, SQLServer, Informix, DB2). I've been wondering if there is a silver-bullet syntax coming from an SQL Standards (For example, SQL92) that would allow me to insert the values without worrying about the underlying database.

  • Something Better than .NET Reflector?

    - by Josh Stodola
    I used to love Reflector back in the day, but ever since RedGate took over it has gone downhill dramatically. Now it forces me to update (which is absolutely ridiculous), half the time the update doesn't go smoothly, and it is increasingly hindering my productivity with each update. I am sick of it, and I am ready for something better. Does anybody know of a better disassembler?

  • Alter highchart output to display start - end date

    - by php_d
    I currently have the following highchart which display a start date and outputs the values for the next 31 days of data. Does anyone know how I may improve on this to include and end date so that I can filter the data by smaller specific amounts? On the x-axis I am also trying to only display labels that have data attached to them and hide any others. Any help is appreciated. My code is as follows: <script type="text/javascript"> var chart; $(document).ready(function() { chart = new Highcharts.Chart({ chart: { renderTo: 'container', type: 'line', marginRight: 130, marginBottom: 25 }, title: { text: '<?php echo $type ?>', x: -20 //center }, xAxis: { categories: [ <?php $start = $_POST["dateStart"]; $dates = array(); for ($i = 0, $days = date('t', strtotime($start)); $i < $days; ++$i) { $dates[] = date('Y-m-d', strtotime($start . ' + ' . $i . ' day')); } echo "'" . implode("', '", $dates) . "'"; ?> ] }, yAxis: { title: { text: 'Total Amount' }, plotLines: [{ value: 0, width: 1, color: '#808080' }] }, tooltip: { formatter: function() { return '<b>'+ this.series.name +'</b><br/>'+ this.x +': '+ this.y; } }, legend: { layout: 'vertical', align: 'right', verticalAlign: 'top', x: -10, y: 100, borderWidth: 0 }, series: [ <?php foreach ($array as $legend => $data) { echo '{'; echo "name: '" . $legend . "',"; $values = array(); for ($i = 0; $i < $days; ++$i) { $date = date('Y-m-d', strtotime($start . ' + ' . $i . ' day')); $values[] = isset($data[$date]) ? $data[$date] : 0; } echo 'data: [' . implode(', ', $values) . '],'; echo '},'; } ?> ] }); }); Thanks

  • What's the worst working environment you've had to suffer?

    - by John
    We'll leave "worst job ever" for another day if it wasn't already done... but after some recent discussions on good environments, what is the worst you've had? I've always been quite lucky - seats that go up and down, some kind of natural light, etc. But I think I dodged a bullet... what horror stories can you share?

  • HttpWebRequest possibly slowing website

    - by Steven Smith
    Using Visual studio 2012, C#.net 4.5 , SQL Server 2008, Feefo, Nopcommerce Hey guys I have Recently implemented a new review service into a current site we have. When the change went live the first day all worked fine. Since then though the sending of sales to Feefo hasnt been working, There are no logs either of anything going wrong. In the OrderProcessingService.cs in Nop Commerce's Service, i call a HttpWebrequest when an order has been confirmed as completed. Here is the code. var email = HttpUtility.UrlEncode(order.Customer.Email.ToString()); var name = HttpUtility.UrlEncode(order.Customer.GetFullName().ToString()); var description = HttpUtility.UrlEncode(productVariant.ProductVariant.Product.MetaDescription != null ? productVariant.ProductVariant.Product.MetaDescription.ToString() : "product"); var orderRef = HttpUtility.UrlEncode(order.Id.ToString()); var productLink = HttpUtility.UrlEncode(string.Format("myurl/p/{0}/{1}", productVariant.ProductVariant.ProductId, productVariant.ProductVariant.Name.Replace(" ", "-"))); string itemRef = ""; try { itemRef = HttpUtility.UrlEncode(productVariant.ProductVariant.ProductId.ToString()); } catch { itemRef = "0"; } var url = string.Format("feefo Url", login, password,email,name,description,orderRef,productLink,itemRef); var request = (HttpWebRequest)WebRequest.Create(url); request.KeepAlive = false; request.Timeout = 5000; request.Proxy = null; using (var response = (HttpWebResponse)request.GetResponse()) { if (response.StatusDescription == "OK") { var stream = response.GetResponseStream(); if(stream != null) { using (var reader = new StreamReader(stream)) { var content = reader.ReadToEnd(); } } } } So as you can see its a simple webrequest that is processed on an order, and all product variants are sent to feefo. Now: this hasnt been happening all week since the 15th (day of the implementation) the site has been grinding to a halt recently. The stream and reader in the the var content is there for debugging. Im wondering does the code redflag anything to you that could relate to the process of website? Also note i have run some SQL statements to see if there is any deadlocks or large escalations, so far seems fine, Logs have also been fine just the usual logging of Bots. Any help would be much appreciated! EDIT: also note that this code is in a method that is called and wrapped in A try catch UPDATE: well forget about the "not sending", thats because i was just told my code was rolled back last week

    We are about to roll out a client server application build with java web start. Our main server is located in a country in Europe and we will have many users downloading our client the first day from all over the world. Since the client application is quite big in MB our wan will be utilized a lot. Is there a way to cache or pre- distribute java web start clients to servers "closer" to the user (for example a local server)? Thanks.

  • jQuery AJAX POST gives undefined index

    - by Sebastian
    My eventinfo.php is giving the following output: <br /> <b>Notice</b>: Undefined index: club in <b>/homepages/19/d361310357/htdocs/guestvibe/wp-content/themes/yasmin/guestvibe/eventinfo.php</b> on line <b>11</b><br /> [] HTML (index.php): <select name="club" class="dropdown" id="club"> <?php getClubs(); ?> </select> jQuery (index.php): <script type="text/javascript"> $(document).ready(function() { $.ajax({ type: "POST", url: "http://www.guestvibe.com/wp-content/themes/yasmin/guestvibe/eventinfo.php", data: $('#club').serialize(), success: function(data) { $('#rightbox_inside').html('<h2>' + $('#club').val() + '<span style="font-size: 14px"> (' + data[0].day + ')</h2><hr><p><b>Entry:</b> ' + data[0].entry + '</p><p><b>Queue jump:</b> ' + data[0].queuejump + '</p><br><p><i>Guestlist closes at ' + data[0].closing + '</i></p>'); }, dataType: "json" }); }); $('#club').change(function(event) { $.ajax({ type: "POST", url: "http://www.guestvibe.com/wp-content/themes/yasmin/guestvibe/eventinfo.php", data: $(this).serialize(), success: function(data) { $('#rightbox_inside').hide().html('<h2>' + $('#club').val() + '<span style="font-size: 14px"> (' + data[0].day + ')</h2><hr><p><b>Entry:</b> ' + data[0].entry + '</p><p><b>Queue jump:</b> ' + data[0].queuejump + '</p><br><p><i>Guestlist closes at ' + data[0].closing + '</i></p>').fadeIn('500'); }, dataType: "json" }); }); </script> I can run alerts from the jQuery, so it is active. I've copied this as is from an old version of the website, but I've changed the file structure (through to move to WordPress) so I suspect the variables might not even be reaching eventinfo.php in the first place... index.php is in wp-content/themes/cambridge and eventinfo.php is in wp-content/themes/yasmin/guestvibe but I've tried to avoid structuring issues by referencing the URL in full. Any ideas?
