  • LF/CR issue with RS232 in Linux

    - by Albinoswordfish
    I've been having this problem where anytime I send a 0xA through an RS-232 in a Linux OS the receiver interprets that as 2 bytes, 0xD and 0xA. Also whenever I receive 0xD the serial port interprets that as 0xA. I've been reading that there are known issues regarding this, has anybody been able to find a solution?

    - by yak
    Im working now on simple gui appllication in Java/C++ and CORBA. I want my client on VirtualBox connect to server on localhost.

  • How do you unit test a unit test?

    - by FlySwat
    I was watching Rob Connerys webcasts on the MVCStoreFront App, and I noticed he was unit testing even the most mundane things, things like: public Decimal DiscountPrice { get { return this.Price - this.Discount; } } Would have a test like: [TestMethod] public void Test_DiscountPrice { Product p = new Product(); p.Price = 100; p.Discount = 20; Assert.IsEqual(p.DiscountPrice,80); } While, I am all for unit testing, I sometimes wonder if this form of test first development is really beneficial, for example, in a real process, you have 3-4 layers above your code (Business Request, Requirements Document, Architecture Document), where the actual defined business rule (Discount Price is Price - Discount) could be misdefined. If that's the situation, your unit test means nothing to you. Additionally, your unit test is another point of failure: [TestMethod] public void Test_DiscountPrice { Product p = new Product(); p.Price = 100; p.Discount = 20; Assert.IsEqual(p.DiscountPrice,90); } Now the test is flawed. Obviously in a simple test, it's no big deal, but say we were testing a complicated business rule. What do we gain here? Fast forward two years into the application's life, when maintenance developers are maintaining it. Now the business changes its rule, and the test breaks again, some rookie developer then fixes the test incorrectly...we now have another point of failure. All I see is more possible points of failure, with no real beneficial return, if the discount price is wrong, the test team will still find the issue, how did unit testing save any work? What am I missing here? Please teach me to love TDD, as I'm having a hard time accepting it as useful so far. I want too, because I want to stay progressive, but it just doesn't make sense to me. EDIT: A couple people keep mentioned that testing helps enforce the spec. It has been my experience that the spec has been wrong as well, more often than not, but maybe I'm doomed to work in an organization where the specs are written by people who shouldn't be writing specs.

  • XML Postback issue

    - by Mikey1980
    I have a script that is designed to parse XML postbacks from Ultracart, right now just dumps it into a MySQL table. The script works fine if I point it to a XML file on my localhost but using 'php://input' it doesn't seem to grabbing anything. My logs show apache returning 200 after the post so I have no idea what could be wrong or how to drill down the issue.. here's the code: $doc = new DOMDocument(); $doc->loadXML($page); $handle = fopen("test2/".time().".xml", "w+"); fwrite($handle,trim($page)); // it doesn't save this either :'( fclose(); require_once('includes/database.php'); $db = new Database('localhost', 'user', 'password', 'db_name'); $data = array(); $exports = $doc->getElementsByTagName("export"); foreach ($exports as $export) { $orders = $export->getElementsByTagName("order"); foreach($orders as $order) { $data['order_id'] = $order->getElementsByTagName("order_id")->item(0)->nodeValue; $data['payment_status'] = $order->getElementsByTagName("payment_status")->item(0)->nodeValue; $date_array = explode(" ",$order->getElementsByTagName("payment_date_time")->item(0)->nodeValue); if ($date_array[1] == 'JAN') { $date_array[1] = '01'; } if ($date_array[1] == 'FEB') { $date_array[1] = '02'; } if ($date_array[1] == 'MAR') { $date_array[1] = '03'; } if ($date_array[1] == 'APR') { $date_array[1] = '04'; } if ($date_array[1] == 'MAY') { $date_array[1] = '05'; } // converts Ultracart date to if ($date_array[1] == 'JUN') { $date_array[1] = '06'; } // MySQL date if ($date_array[1] == 'JUL') { $date_array[1] = '07'; } if ($date_array[1] == 'AUG') { $date_array[1] = '08'; } if ($date_array[1] == 'SEP') { $date_array[1] = '09'; } if ($date_array[1] == 'OCT') { $date_array[1] = '10'; } if ($date_array[1] == 'NOV') { $date_array[1] = '11'; } if ($date_array[1] == 'DEC') { $date_array[1] = '12'; } $data['payment_date'] = $date_array[2]."-".$date_array[1]."-".$date_array[0]; $data['payment_time'] = $date_array[3]; //... we'll skip this, there are 80 some elements $data['discount'] = $order->getElementsByTagName("discount")->item(0)->nodeValue; $data['distribution_center_code'] = $order->getElementsByTagName("distribution_center_code")->item(0)->nodeValue; } } } $db->insert('order_history',$data); } else die('ERROR: Token Check Failed!');

  • Symfony 1.4 Layout footer glitch: Footer div is echoed out with $sf_content

    - by Parijat Kalia
    I have a very simple Layout for my application. A header, the main content, and a footer. Semantically, they are rendered like this: <body> <div id = "header"> </div> <div id = "content"> </div> <div id = "footer"> </div> </body> The corresponding CSS is very basic as well: #header{ width:100%; min-height:10%; } #center{ width:100%; min-height:80%; } #footer{ width:100%; min-height:10%: } As you would know in the layout page, here is how the content is rendered: <div id= "content"> <?php echo $sf_content; ?> </div> All of the above is very fine and it renders itself as it is supposed to. But there is a glitch with this, the moment i put in <?php echo $sf_content; ?> the footer is included as part of the content and not as a div that is after the #content markup. Essentially, I get this: <div id = "header"></div> <div id = "content> <div id ="symfony_template_to_be_rendered"> <!-- all web application related content like forms etc. --> </div> <div id = "footer">Footer material </div> </div> As you can see, for some weird reason, the footer moved up along with the symfony content. Clearly this is a glitch because if I remove the php hash $sf_content part from the div tags in my layouts, then the footer renders itself as and where it should be and everything takes up the required dimensions. What's going on here?

I have telnet'ed into the daemon and am listening on the port, and can send the daemon commands via the CLI.

I know of commands like 'flush_all' and 'stats' but those are not quite sufficient for what I want to do.

  • Problem with jQuery selector and MasterPage

    - by Daemon
    Hi, I have a problem with a master page containing a asp:textbox that I'm trying to access using jQuery. I have read lot sof thread regarding this and tried all the different approaches I have seen, but regardless, the end result end up as Undefined. This is the relevant part of the MasterPage code: <p><asp:Label ID="Label1" AssociatedControlID="osxinputfrom" runat="server">Navn</asp:Label><asp:TextBox CssClass="osxinputform" ID="osxinputfrom" runat="server"></asp:TextBox></p> When I click the button, the following code from a jQuery .js file is run: show: function(d) { $('#osx-modal-content .osxsubmitbutton').click(function (e) { e.preventDefault(); if (OSX.validate()){ $('#osx-modal-data').fadeOut(200); d.container.animate( {height:80}, 500, function () { $('#osx-modal-data').html("<h2>Sender...</h2>").fadeIn(250, function () { $.ajax({ type: "POST", url: "Default.aspx/GetDate", data: "{'from':'" + $("#osxinputfrom").val() + "','mailaddress':'" + $("#osxinputmail").val() + "','header':'Test3','message':'Test4'}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { $('#osx-modal-data').fadeOut(200, function () { $('#osx-modal-data').html('<h2>Meldingen er sendt!</h2>'); $('#osx-modal-data').fadeIn(200); }); }, error: function(msg){ $('#osx-modal-data').fadeOut(200, function () { $('#osx-modal-data').html('<h2>Feil oppstod ved sending av melding!</h2>'); $('#osx-modal-data').fadeIn(200); }); } }); }); } ); } else{ $('#osxinputstatus').fadeOut(250, function () { $('#osxinputstatus').html('<p id="osxinputstatus">' + OSX.message + '</a>'); $('#osxinputstatus').fadeIn(250); }); } }); }, So the problem here is that $("#osxinputfrom").val() evaluated to Undefined. I understand that the masterpage will add some prefix to the ID, so I tried using the ID from the page when it's run that ends up as ct100_osxinputfrom, and I also tried some other hinds that I found while searching like $("#<%=osxinputfrom.ClientID%"), but it ends up as Undefined in the method that is called from the jQuery ajax method anyway. The third and fourth parameters to the ajay function that is hardcoded as Test3 and Test4 comes fine in the C# backend method. So my question is simply: How can I rewrite the jQuery selector to fetch the correct value from the textbox? (before I used master pages it worked fine by the way) Best regards Daemon

  • Is it possible to change HANDLE that has been opened for synchronous I/O to be opened for asynchrono

    - by Martin Dobšík
    Dear all, Most of my daily programming work in Windows is nowadays around I/O operations of all kind (pipes, consoles, files, sockets, ...). I am well aware of different methods of reading and writing from/to different kinds of handles (Synchronous, asynchronous waiting for completion on events, waiting on file HANDLEs, I/O completion ports, and alertable I/O). We use many of those. For some of our applications it would be very useful to have only one way to treat all handles. I mean, the program may not know, what kind of handle it has received and we would like to use, let's say, I/O completion ports for all. So first I would ask: Let's assume I have a handle: HANDLE h; which has been received by my process for I/O from somewhere. Is there any easy and reliable way to find out what flags it has been created with? The main flag in question is FILE_FLAG_OVERLAPPED. The only way known to me so far, is to try to register such handle into I/O completion port (using CreateIoCompletionPort()). If that succeeds the handle has been created with FILE_FLAG_OVERLAPPED. But then only I/O completion port must be used, as the handle can not be unregistered from it without closing the HANDLE h itself. Providing there is an easy a way to determine presence of FILE_FLAG_OVERLAPPED, there would come my second question: Is there any way how to add such flag to already existing handle? That would make a handle that has been originally open for synchronous operations to be open for asynchronous. Would there be a way how to create opposite (remove the FILE_FLAG_OVERLAPPED to create synchronous handle from asynchronous)? I have not found any direct way after reading through MSDN and googling a lot. Would there be at least some trick that could do the same? Like re-creating the handle in same way using CreateFile() function or something similar? Something even partly documented or not documented at all? The main place where I would need this, is to determine the the way (or change the way) process should read/write from handles sent to it by third party applications. We can not control how third party products create their handles. Dear Windows gurus: help please! With regards Martin
