  • Problem in In-App purchase-consumable model

    - by kunal-dutta
    I have created a nonconsumable in app purchase item and now I want to create a consumable in-app purchase by which a user to buy it every time he uses it,and also I want to create a subscription model In-App purchase. Everything works as expected except when I buy the item more than one time, iPhone pop ups a message saying "You've already purchased the item. Do You want to buy it again?". Is It possible to disable this dialog and proceed to the actual purchase?And what will have to change in following code with different model:- in InApp purchase manager.m: @implementation InAppPurchaseManager //@synthesize purchasableObjects; //@synthesize storeObserver; @synthesize proUpgradeProduct; @synthesize productsRequest; //BOOL featureAPurchased; //BOOL featureBPurchased; //static InAppPurchaseManager* _sharedStoreManager; // self (void)dealloc { //[_sharedStoreManager release]; //[storeObserver release]; [super dealloc]; } (void)requestProUpgradeProductData { NSSet *productIdentifiers = [NSSet setWithObject:@"com.vigyaapan.iWorkOut1" ]; productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers]; productsRequest.delegate = self; [productsRequest start]; // we will release the request object in the delegate callback } pragma mark - pragma mark SKProductsRequestDelegate methods (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { //NSArray *products = response.products; //proUpgradeProduct = [products count] == 1 ?

  • MySQL Binary Storage using BLOB VS OS File System: large files, large quantities, large problems.

    - by Quantico773
    Hi Guys, Versions I am running (basically latest of everything): PHP: 5.3.1 MySQL: 5.1.41 Apache: 2.2.14 OS: CentOS (latest) Here is the situation. I have thousands of very important documents, ranging from customer contracts to voice signatures (recordings of customer authorisation for contracts), with file types including, but not limited to jpg, gif, png, tiff, doc, docx, xls, wav, mp3, pdf, etc. All of these documents are currently stored on several servers including Windows 32 bit, CentOS and Mac, among others. Some files are also stored on employees desktop computers and laptops, and some are still hard copies stored in hundreds of boxes and filing cabinets. Now because customers or lawyers could demand evidence of contracts at any time, my company has to be able to search and locate the correct document(s) effectively, for this reason ALL of these files have to be digitised (if not already) and correlated into some sort of order for searching and accessing. As the programmer, I have created a full Customer Relations Management tool that the whole company uses. This includes Customer Profiles management, Order and job Tracking tools, Job/sale creation and management modules, etc, and at the moment any file that is needed at a customer profile level (drivers licence, credit authority, etc) or at a job/sale level (contracts, voice signatures, etc) can be uploaded to the server and sits in a parent/child hierarchy structure, just like Windows Explorer or any other typical file managment model. The structure appears as such: drivers_license |- DL_123.jpg voice_signatures |- VS_123.wav |- VS_4567.wav contracts So the files are uplaoded using PHP and Apache, and are stored in the file system of the OS. At the time of uploading, certain information about the file(s) is stored in a MySQL database. Some of the information stored is: TABLE: FileUploads FileID CustomerID (the customer id that the file belongs to, they all have this.) JobID/SaleID (the id of the job/sale associated, if any.) FileSize FileType UploadedDateTime UploadedBy FilePath (the directory path the file is stored in.) FileName (current file name of uploaded file, combination of CustomerID and JobID/SaleID if applicable.) FileDescription OriginalFileName (original name of the source file when uploaded, including extension.) So as you can see, the file is linked to the database by the File Name. When I want to provide a customers' files for download to a user all I have to do is "SELECT * FROM FileUploads WHERE CustomerID = 123 OR JobID = 2345;" and this will output all the file details I require, and with the FilePath and FileName I can provide the link for download. http... server / FilePath / FileName There are a number of problems with this method: Storing files in this "database unconcious" environment means data integrity is not kept. If a record is deleted, the file may not be deleted also, or vice versa. Files are strewn all over the place, different servers, computers, etc. The file name is the ONLY thing matching the binary to the database and customer profile and customer records. etc, etc. There are so many reasons, some of which are described here: http://www.dreamwerx.net/site/article01 . Also there is an interesting article here too: sietch.net/ViewNewsItem.aspx?NewsItemID=124 . SO, after much research I have pretty much decided I am going to store ALL of these files in the database, as a BLOB or LONGBLOB, but there are still many considerations before I do this. I know that storing them in the database is a viable option, however there are a number of methods of storing them. I also know storing them is one thing; correlating and accessing them in a manageable way is another thing entirely. The article provided at this link: dreamwerx.net/site/article01 describes a way of splitting the uploaded binary files into 64kb chunks and storing each chunk with the FileID, and then streaming the actual binary file to the client using headers. This is a really cool idea since it alleviates preassure on the servers memory; instead of loading an entire 100mb file into the RAM and then sending it to the client, it is doing it 64kb at a time. I have tried this (and updated his scripts) and this is totally successful, in a very small frame of testing. So if you are in agreeance that this method is a viable, stable and robust long-term option to store moderately large files (1kb to couple hundred megs), and large quantities of these files, let me know what other considerations or ideas you have. Also, I am considering getting a current "File Management" PHP script that gives an interface for managing files stored in the File System and converting it to manage files stored in the database. If there is already any software out there that does this, please let me know. I guess there are many questions I could ask, and all the information is up there ^^ so please, discuss all aspects of this and we can pass ideas back and forth and teach each other. Cheers, Quantico773

  • springTestContextBeforeTestMethod failed in Maven spring-test

    - by joejax
    I try to setup a project with spring-test using TestNg in Maven. The code is like: @ContextConfiguration(locations={"test-context.xml"}) public class AppTest extends AbstractTestNGSpringContextTests { @Test public void testApp() { assert true; } } A test-context.xml simply defined a bean: <bean id="app" class="org.sonatype.mavenbook.simple.App"/> I got error for Failed to load ApplicationContext when running mvn test from command line, seems it cannot find the test-context.xml file; however, I can get it run correctly inside Eclipse (with TestNg plugin). So, test-context.xml is under src/test/resources/, how do I indicate this in the pom.xml so that 'mvn test' command will work? Thanks, UPDATE: Thanks for the reply. Cannot load context file error was caused by I moved the file arround in different location since I though the classpath was the problem. Now I found the context file seems loaded from the Maven output, but the test is failed: Running TestSuite May 25, 2010 9:55:13 AM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions INFO: Loading XML bean definitions from class path resource [test-context.xml] May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.context.support.GenericApplicationContext@171bbc9: display name [org.springframework.context.support.GenericApplicationContext@171bbc9]; startup date [Tue May 25 09:55:13 PDT 2010]; root of context hierarchy May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext obtainFreshBeanFactory INFO: Bean factory for application context [org.springframework.context.support.GenericApplicationContext@171bbc9]: org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99 May 25, 2010 9:55:13 AM org.springframework.beans.factory.support.DefaultListableBeanFactory preInstantiateSingletons INFO: Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99: defining beans [app,org.springframework.context.annotation.internalCommonAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor]; root of factory hierarchy Tests run: 3, Failures: 2, Errors: 0, Skipped: 1, Time elapsed: 0.63 sec <<< FAILURE!

UPDATE: I think I got the problem (still don't know why) - Whenever I extends AbstractTestNGSpringContextTests or AbstractTransactionalTestNGSpringContextTests, the test will failed with this error: Failed tests: springTestContextBeforeTestMethod(org.sonatype.mavenbook.simple.AppTest) springTestContextAfterTestMethod(org.sonatype.mavenbook.simple.AppTest) So, eventually the error went away when I override the two methods. I don't think this is the right way, didn't find much info from spring-test doc. If you know spring test framework, please shred some light on this.

  • HttpModule Init method is called several times - why?

    - by MartinF
    I was creating a http module and while debugging I noticed something which at first (at least) seemed like weird behaviour. When i set a breakpoint in the init method of the httpmodule i can see that the http module init method is being called several times even though i have only started up the website for debugging and made one single request (sometimes it is hit only 1 time, other times as many as 10 times). I know that I should expect several instances of the HttpApplication to be running and for each the http modules will be created, but when i request a single page it should be handled by a single http application object and therefore only fire the events associated once, but still it fires the events several times for each request which makes no sense - other than it must have been added several times within that httpApplication - which means it is the same httpmodule init method which is being called every time and not a new http application being created each time it hits my break point (see my code example at the bottom etc.). What could be going wrong here ? is it because i am debugging and set a breakpoint in the http module? It have noticed that it seems that if i startup the website for debugging and quickly step over the breakpoint in the httpmodule it will only hit the init method once and the same goes for the eventhandler. If I instead let it hang at the breakpoint for a few seconds the init method is being called several times (seems like it depends on how long time i wait before stepping over the breakpoint). Maybe this could be some build in feature to make sure that the httpmodule is initialised and the http application can serve requests , but it also seems like something that could have catastrophic consequences. This could seem logical, as it might be trying to finish the request and since i have set the break point it thinks something have gone wrong and try to call the init method again ? soo it can handle the request ? But is this what is happening and is everything fine (i am just guessing), or is it a real problem ? What i am specially concerned about is that if something makes it hang on the "production/live" server for a few seconds a lot of event handlers are added through the init and therefore each request to the page suddenly fires the eventhandler several times. This behaviour could quickly bring any site down. I have looked at the "original" .net code used for the httpmodules for formsauthentication and the rolemanagermodule etc but my code isnt any different that those modules uses. My code looks like this. public void Init(HttpApplication app) { if (CommunityAuthenticationIntegration.IsEnabled) { FormsAuthenticationModule formsAuthModule = (FormsAuthenticationModule) app.Modules["FormsAuthentication"]; formsAuthModule.Authenticate += new FormsAuthenticationEventHandler(this.OnAuthenticate); } } here is an example how it is done in the RoleManagerModule from the .NET framework public void Init(HttpApplication app) { if (Roles.Enabled) { app.PostAuthenticateRequest += new EventHandler(this.OnEnter); app.EndRequest += new EventHandler(this.OnLeave); } } Do anyone know what is going on? (i just hope someone out there can tell me why this is happening and assure me that everything is perfectly fine) :) UPDATE: I have tried to narrow down the problem and so far i have found that the Init method being called is always on a new object of my http module (contary to what i thought before). I seems that for the first request (when starting up the site) all of the HttpApplication objects being created and its modules are all trying to serve the first request and therefore all hit the eventhandler that is being added. I cant really figure out why this is happening. If i request another page all the HttpApplication's created (and their moduless) will again try to serve the request causing it to hit the eventhandler multiple times. But it also seems that if i then jump back to the first page (or another one) only one HttpApplication will start to take care of the request and everything is as expected - as long as i dont let it hang at a break point. If i let it hang at a breakpoint it begins to create new HttpApplication's objects and starts adding HttpApplications (more than 1) to serve/handle the request (which is already in process of being served by the HttpApplication which is currently stopped at the breakpoint). I guess or hope that it might be some intelligent "behind the scenes" way of helping to distribute and handle load and / or errors. But I have no clue. I hope some out there can assure me that it is perfectly fine and how it is supposed to be?

  • Trouble on setting SSL certificates for Virtual Hosts using Apache\Phusion Passenger in localhost

    - by user502052
    I am using Ruby on Rails 3 and I would like to make to work HTTPS connections on localhost. I am using: Apache v2 + Phusion Passenger Mac OS + Snow Leopard v10.6.6 My Ruby on Rails installation use the Typhoeus gem (it is possible to use the Ruby net\http library but the result doesn't change) to make HTTP requests over HTTPS. I created self-signed ca.key, pjtname.crt and pjtname.key as detailed on the Apple website. Notice: Following instruction from the Apple website, on running the openssl req -new -key server.key -out server.csr command (see the link) at this point Common Name (eg, YOUR name) []: (this is the important one) I entered *pjtname.com so that is valid for all sub_domain of that site. In my Apache httpd.conf I have two virtual hosts configured in this way: # Secure (SSL/TLS) connections #Include /private/etc/apache2/extra/httpd-ssl.conf # # Note: The following must must be present to support # starting without SSL on platforms with no /dev/random equivalent # but a statically compiled-in mod_ssl. # <IfModule ssl_module> SSLRandomSeed startup builtin SSLRandomSeed connect builtin </IfModule> Include /private/etc/apache2/other/*.conf # Passenger configuration LoadModule passenger_module /Users/<my_user_name>/.rvm/gems/ruby-1.9.2-p136/gems/passenger-3.0.2/ext/apache2/mod_passenger.so PassengerRoot /Users/<my_user_name>/.rvm/gems/ruby-1.9.2-p136/gems/passenger-3.0.2 PassengerRuby /Users/<my_user_name>/.rvm/wrappers/ruby-1.9.2-p136/ruby # Go ahead and accept connections for these vhosts # from non-SNI clients SSLStrictSNIVHostCheck off # Ensure that Apache listens on port 443 Listen 443 # Listen for virtual host requests on all IP addresses NameVirtualHost *:80 NameVirtualHost *:443 # # PJTNAME.COM and subdomains SETTING # <VirtualHost *:443> # Because this virtual host is defined first, it will # be used as the default if the hostname is not received # in the SSL handshake, e.g. if the browser doesn't support # SNI.

All this means that something is wrong. So, what I have to do to avoid the "Peer certificate cannot be authenticated with known CA certificates" warning and make the HTTPS request to work? Where is\are the error\errors (I think in the Apache configuration, but where?!)? P.S.: if you need some more info, let me know.

  • ASP.NET treeview populate child nodes. How can I avoid a postback to server?

    - by mas_oz2k1
    I am trying to test populate on demand for a treeview. I follow the procedure from these links: http://msdn.microsoft.com/en-us/library/e8z5184w.aspx But the treeview still make a postback to the server if I expanded one of the tree nodes (If you put a breakpoint in the first line of Page_load event), thus refreshing the whole page. I am using VS2005 and Asp.net 2.0 (but the same issue occurs in VS2008) My simple test page markup is: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="aspTreeview.aspx.cs" Inherits="aspTreeview" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <div> <table> <tr> <td style="height: 80%; width: 45%;"> <asp:Panel ID="Panel1" runat="server" BorderColor="#0033CC" BorderStyle="Solid" ScrollBars="Both"> <asp:TreeView ID="TreeView1" runat="server" ShowLines="True" PopulateNodesFromClient="True" EnableClientScript="True" NodeWrap="True" ontreenodepopulate="TreeView1_TreeNodePopulate" ExpandDepth="0"> </asp:TreeView> </asp:Panel> </td> <td style="width: 10%; height: 80%;" > <div> <asp:Button ID="Button1" runat="server" Text="->" onclick="Button1_Click" /> </div> <div> <asp:Button ID="Button2" runat="server" Text="<-" /> </div> </td> <td style="width: 136px; height: 80%"> <asp:Panel ID="Panel2" runat="server" BorderColor="Lime" BorderStyle="Solid"> <asp:TreeView ID="TreeView2" runat="server" ShowLines="True" ExpandDepth="0"> </asp:TreeView> </asp:Panel> </td> </tr> <tr> <td> </td> <td> </td> <td style="width: 136px"> </td> </tr> </table> </div> </form> </body> </html> The code behind is: protected void Page_Load(object sender, EventArgs e) { Debug.WriteLine("Page_Load started."); if (!IsPostBack) { if (Request.Browser.SupportsCallback) Debug.WriteLine("Browser supports callback scripts."); for (int i = 0; i < 3; i++) { TreeNode node = new TreeNode("ENTRY " + i.ToString()); node.Value = i.ToString(); node.PopulateOnDemand = true; node.Expanded = false; TreeView1.Nodes.Add(node); } } Debug.WriteLine("Page_Load finished."); } protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e) { TreeNode targetNode = e.Node; for (int j = 0; j < 4200; j++) { TreeNode subnode = new TreeNode(String.Format("Sub ENTRY {0} {1}", targetNode.Value, j)); subnode.PopulateOnDemand = true; subnode.Expanded = false; targetNode.ChildNodes.Add(subnode); } }

  • Problem with jQuery and ASP.Net MVC

    - by robert_d
    I have a problem with jQuery, here is how my web app works Search web page which contains a form and jQuery script posts data to Search() action in Home controller after user clicks button1 button. Search.aspx: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<GLSChecker.Models.WebGLSQuery>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Title </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Search</h2> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm()) {%> <fieldset> <div class="editor-label"> <%: Html.LabelFor(model => model.Url) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Url, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Url) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Location) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Location, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Location) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.KeywordLines) %> </div> <div class="editor-field"> <%: Html.TextAreaFor(model => model.KeywordLines, 10, 60, null)%> <%: Html.ValidationMessageFor(model => model.KeywordLines)%> </div> <p> <input id ="button1" type="submit" value="Search" /> </p> </fieldset> <% } %> <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> jQuery("#button1").click(function (e) { window.setInterval(refreshResult, 5000); }); function refreshResult() { jQuery("#divResult").load("/Home/Refresh"); } </script> <div id="divResult"> </div> </asp:Content> [HttpPost] public ActionResult Search(WebGLSQuery queryToCreate) { if (!ModelState.IsValid) return View("Search"); queryToCreate.Remote_Address = HttpContext.Request.ServerVariables["REMOTE_ADDR"]; Session["Result"] = null; SearchKeywordLines(queryToCreate); Thread.Sleep(15000); return View("Search"); }//Search() After button1 button is clicked the above script from Search web page runs Search() action in controller runs for longer period of time. I simulate this in testing by putting Thread.Sleep(15000); in Search()action. 5 sec. after Submit button was pressed, the above jQuery script calls Refresh() action in Home controller. public ActionResult Refresh() { ViewData["Result"] = DateTime.Now; return PartialView(); } Refresh() renders this partial <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" % <%= ViewData["Result"] % The problem is that in Internet Explorer 8 there is only one request to /Home/Refresh; in Firefox 3.6.3 all requests to /Home/Refresh are made but nothing is displayed on the web page. I would be grateful for helpful suggestions.

  • Firefox and TinyMCE 3.4.9 won't play nice together

    - by Patricia
    I've submitted a bug to the tinyMCE people, but i'm hoping someone else has come across this and has a suitable workaround. Here's the situation: I've got a form with a tinyMCE control that i load into a jquery dialog. it works great the first time, then after they close it, and open a new one. any interaction with the tinyMCE control gives: "Node cannot be used in a document other than the one in which it was created" it also doesn't fill the control with the text it's supposed to be prepopulated with. In my jquery dialogs i have the following scripts in my beforeClose handler: if (typeof tinyMCE != 'undefined') { $(this).find(':tinymce').each(function () { var theMce = $(this); tinyMCE.execCommand('mceFocus', false, theMce.attr('id')); tinyMCE.execCommand('mceRemoveControl', false, theMce.attr('id')); $(this).remove(); }); } and here's my tinyMCE setup script: $('#' + controlId).tinymce({ script_url: v2ScriptPaths.TinyMCEPath, mode: "none", elements: controlId, theme: "advanced", plugins: "paste", paste_retain_style_properties: "*", theme_advanced_toolbar_location: "top", theme_advanced_buttons1: "bold, italic, underline, strikethrough, separator, justifyleft, justifycenter, justifyright, justifyfull, indent, outdent, separator, undo, redo, separator, numlist, bullist, hr, link, unlink,removeformat", theme_advanced_buttons2: "fontsizeselect, forecolor, backcolor, charmap, pastetext,pasteword,selectall, sub, sup", theme_advanced_buttons3: "", language: v2LocalizedSettings.languageCode, gecko_spellcheck : true, onchange_callback: function (editor) { tinyMCE.triggerSave(); }, setup: function (editor) { editor.onInit.add(function (editor, event) { if (typeof v2SetInitialContent == 'function') { v2SetInitialContent(); } }) } }); is there anything obvious here? i've got all that complicated removal stuff in the close b/c tinymce doesn't like having it's html removed without it being removed. the setInitialContent() stuff is just so i can pre-load it with their email signature if they have one. it's broken with or without that code so that's not the problem. i was forced to update to 3.4.9 because of this issue: http://www.tinymce.com/forum/viewtopic.php?id=28400 so if someone can solve that, it would help this situation to. I have tried the suggestion from aknosis with no luck. EDIT: I originally thought this only affected firefox 11, but i have downloaded 10, and it is also affected. EDIT: Ok, i've trimmed down all my convoluted dynamic forms and links that cause this into a fairly simple example. the code for the base page: <a href="<%=Url.Action(MVC.Temp.GetRTEDialogContent)%>" id="TestSendEmailDialog">Get Dialog</a> <div id="TestDialog"></div> <script type="text/javascript"> $('#TestSendEmailDialog').click(function (e) { e.preventDefault(); var theDialog = buildADialog('Test', 500, 800, 'TestDialog'); theDialog.dialog('open'); theDialog.empty().load($(this).attr('href'), function () { }); }); function buildADialog(title, height, width, dialogId, maxHeight) { var customDialog = $('#' + dialogId); customDialog.dialog('destory'); customDialog.dialog({ title: title, autoOpen: false, height: height, modal: true, width: width, close: function (ev, ui) { $(this).dialog("destroy"); $(this).empty(); }, beforeClose: function (event, ui) { if (typeof tinyMCE != 'undefined') { $(this).find(':tinymce').each(function () { var theMce = $(this); tinyMCE.execCommand('mceFocus', false, theMce.attr('id')); tinyMCE.execCommand('mceRemoveControl', false, theMce.attr('id')); $(this).remove(); }); } } }); return customDialog; } </script> and the code for the page that is loaded into the dialog: <form id="SendAnEmailForm" name="SendAnEmailForm" enctype="multipart/form-data" method="post"> <textarea cols="50" id="MessageBody" name="MessageBody" rows="10" style="width: 710px; height:200px;"></textarea> </form> <script type="text/javascript"> $(function () { $('#MessageBody').tinymce({ script_url: v2ScriptPaths.TinyMCEPath, mode: "exact", elements: 'MessageBody', theme: "advanced", plugins: "paste, preview", paste_retain_style_properties: "*", theme_advanced_toolbar_location: "top", theme_advanced_buttons1: "bold, italic, underline, strikethrough, separator, justifyleft, justifycenter, justifyright, justifyfull, indent, outdent, separator, undo, redo, separator, numlist, bullist, hr, link, unlink,removeformat", theme_advanced_buttons2: "fontsizeselect, forecolor, backcolor, charmap, pastetext,pasteword,selectall, sub, sup, preview", theme_advanced_buttons3: "", language: 'EN', gecko_spellcheck: true, onchange_callback: function (editor) { tinyMCE.triggerSave(); } }); }); </script> a very interesting thing i noticed, if i move the tinyMCE setup into the load callback, it seems to work. this isn't really a solution though, because when i'm loading dialogs, i don't know in the code ahead of time if it has tinyMCE controls or not!

  • SecurityException in Sandboxed AppDomain

    - by Galen
    I'm attempting to use C# as a scripting language using CSharpCodeProvider (using VS2010 and .NET 4.0). I want the scripts to be run in a restricted AppDomain with minimal permissions. Currently, I'm getting an exception while trying to instantiate a class in the AppDomain (The call to CreateInstanceAndUnwrap()). Here is some simplified code that reproduces the exception: using System; using System.Collections.Generic; using Microsoft.CSharp; using System.CodeDom; using System.CodeDom.Compiler; using System.Security; using System.Security.Policy; using System.Security.Permissions; using System.Reflection; using System.Runtime.Remoting; namespace ConsoleApp { class Program { static void Main(string[] args) { // set permissions PermissionSet permissions = new PermissionSet(PermissionState.None); permissions.AddPermission(new SecurityPermission( SecurityPermissionFlag.Execution)); AppDomainSetup adSetup = new AppDomainSetup(); adSetup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; //Create a list of fully trusted assemblies Assembly[] asms = AppDomain.CurrentDomain.GetAssemblies(); List<StrongName> sns = new List<StrongName>(); for (int x = 0; x < asms.Length; x++) { StrongName sn = asms[x].Evidence.GetHostEvidence<StrongName>(); if (sn != null && sns.Contains(sn) == false) sns.Add(sn); } //this includes: "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" AppDomain domain = AppDomain.CreateDomain("NewAppDomain", AppDomain.CurrentDomain.Evidence, adSetup, permissions);//, sns);//, sn4, sn, sn2, sn3); try { String asmName = Assembly.GetExecutingAssembly().FullName; String typeName = typeof(ConsoleApp.ScriptRunner).FullName; //Throws exception here ScriptRunner scriptRunner = domain.CreateInstanceAndUnwrap(asmName, typeName) as ScriptRunner; } catch (SecurityException se) { System.Diagnostics.Debug.WriteLine(se.Message); } catch (Exception ex) { System.Diagnostics.Debug.WriteLine(ex.Message); } } } public class ScriptRunner : MarshalByRefObject { public ScriptRunner() { //A breakpoint placed here is never reached.

  • website creation - for non web programmers?

    - by Tim
    I thought I would find decent questions and answers for this, but none really caught my eye... I am a C++ developer and I own a few domains. I'd like to start off with simple web sites for each with a minimum of time and fuss and minimum learning. I have too many projects going and don't have the time to learn how to build websites. One is for a company that currently has only a single product with custom development as well. I hacked together some really bad html with paypal links on it. It is just one simple product. I want to add uservoice to it and maybe some other stuff like FAQ, forums, etc. Right now I just link to a google group I created. Another is a startup in development phase, but we want to provide simple content like whitepapers and press releases and a section for investors. - mostly an "about us" type of thing. We will also be providing details about our product. Then there is a blog site - currently using godaddy's quickblogcast. Not a bad start but I suspect I want to move to something else. The question is - is there a framework that I can use that will make decent, if not outstanding, sites? Again, I have my hands full with three projects in addition to my day job and don't have time to learn web programming. I also don;t want to just pay a web person and then be out in the cold for upgrades, changes, etc. I have been burned before. I am happy with a web-based app or a desktop app that builds html or whatever and then I can ftp it up to the hosting servers. To summarize: - simple to get started - low time to get a web page going - ability to integrate with a few hand-done pages - pay pal integration - uservoice integration - ability to put under my svn would be nice too EDIT Thanks to the responders. I understand now why my original searches failed. I was not searching for "CMS". I'll go back and do that. I would expect that this is a many-times-duplicate... EDIT: I am considering using Wordpress and Drupal - one for each of the sites. I did one Drupal site quickly just so I could qualify for one of the Microsoft programs for discounted dev tools - anyway - it was a quick and dirty homepage and I am still on the learning curve. I look forward to playing with it. So far it has been ok. I am not sure about doing a taste-test between the two - might be a waste of time where I could just become that much better at Drupal faster than spending time on wordpress... Will keep updated. EDIT: Selecting the Drupal answer by slim for now. That is what I am going with. Don't have time to check them all out. Wordpress sounds like a good option too, but such limited time... Results: I have tried wordpress and drupal so far. Wordpress is great for blogging or for a site that you want to run ads from, but I disagree that it is ready for a corporate site, unless you want to spend lots of time making your own theme, etc. But if you spend that time, why not work with drupal? Drupal was a little intimidating at first - but after spending about 4 hours reading the overview and step-by-step guide online was a HUGE step. I got a simple site up and running easily after that. Trying to make a website just by going to the admin panel without reading anything is a waste of time. You really need to read the docs. The site is great. start here: http://drupal.org/getting-started I'd suggest drupal to anyone. It has amazing capabilities, lots of support and lots of users. Just doing blogging? Wordpress is really great for that. So now I've got two sites running with a lot of the functionality I wanted - and they look good. ONE MORE EDIT Well, I have switched back to wordpress after buying a theme and then getting help from web developers. I guess either one will work - it is just a matter of getting comfortable witht he basics, using the right tools and trying things out.

  • Node.js vs PHP processing speed

    - by Cody Craven
    I've been looking into node.js recently and wanted to see a true comparison of processing speed for PHP vs Node.js. In most of the comparisons I had seen, Node trounced Apache/PHP set ups handily. However all of the tests were small 'hello worlds' that would not accurately reflect any webpage's markup. So I decided to create a basic HTML page with 10,000 hello world paragraph elements. In these tests Node with Cluster was beaten to a pulp by PHP on Nginx utilizing PHP-FPM. So I'm curious if I am misusing Node somehow or if Node is really just this bad at processing power. Note that my results were equivalent outputting "Hello world\n" with text/plain as the HTML, but I only included the HTML as it's closer to the use case I was investigating. My testing box: Core i7-2600 Intel CPU (has 8 threads with 4 cores) 8GB DDR3 RAM Fedora 16 64bit Node.js v0.6.13 Nginx v1.0.13 PHP v5.3.10 (with PHP-FPM) My test scripts: Node.js script var cluster = require('cluster'); var http = require('http'); var numCPUs = require('os').cpus().length; if (cluster.isMaster) { // Fork workers. for (var i = 0; i < numCPUs; i++) { cluster.fork(); } cluster.on('death', function (worker) { console.log('worker ' + worker.pid + ' died'); }); } else { // Worker processes have an HTTP server. http.Server(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); res.write('<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n'); for (var i = 0; i < 10000; i++) { res.write('<p>Hello world</p>\n'); } res.end('</body>\n</html>'); }).listen(80); } This script is adapted from Node.js' documentation at http://nodejs.org/docs/latest/api/cluster.html PHP script <?php echo "<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n"; for ($i = 0; $i < 10000; $i++) { echo "<p>Hello world</p>\n"; } echo "</body>\n</html>"; My results Node.js $ ab -n 500 -c 20 http://speedtest.dev/ This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: Server Hostname: speedtest.dev Server Port: 80 Document Path: / Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 14.603 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95066500 bytes HTML transferred: 95035000 bytes Requests per second: 34.24 [#/sec] (mean) Time per request: 584.123 [ms] (mean) Time per request: 29.206 [ms] (mean, across all concurrent requests) Transfer rate: 6357.45 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 2 Processing: 94 547 405.4 424 2516 Waiting: 0 331 399.3 216 2284 Total: 95 547 405.4 424 2516 Percentage of the requests served within a certain time (ms) 50% 424 66% 607 75% 733 80% 813 90% 1084 95% 1325 98% 1843 99% 2062 100% 2516 (longest request) PHP/Nginx $ ab -n 500 -c 20 http://speedtest.dev/test.php This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: nginx/1.0.13 Server Hostname: speedtest.dev Server Port: 80 Document Path: /test.php Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 0.130 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95109000 bytes HTML transferred: 95035000 bytes Requests per second: 3849.11 [#/sec] (mean) Time per request: 5.196 [ms] (mean) Time per request: 0.260 [ms] (mean, across all concurrent requests) Transfer rate: 715010.65 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 1 Processing: 3 5 0.7 5 7 Waiting: 1 4 0.7 4 7 Total: 3 5 0.7 5 7 Percentage of the requests served within a certain time (ms) 50% 5 66% 5 75% 5 80% 6 90% 6 95% 6 98% 6 99% 6 100% 7 (longest request) Additional details Again what I'm looking for is to find out if I'm doing something wrong with Node.js or if it is really just that slow compared to PHP on Nginx with FPM. I certainly think Node has a real niche that it could fit well, however with these test results (which I really hope I made a mistake with - as I like the idea of Node) lead me to believe that it is a horrible choice for even a modest processing load when compared to PHP (let alone JVM or various other fast solutions). As a final note, I also tried running an Apache Bench test against node with $ ab -n 20 -c 20 http://speedtest.dev/ and consistently received a total test time of greater than 0.900 seconds.

  • What does Ruby have that Python doesn't, and vice versa?

    - by Lennart Regebro
    There is a lot of discussions of Python vs Ruby, and I all find them completely unhelpful, because they all turn around why feature X sucks in language Y, or that claim language Y doesn't have X, although in fact it does. I also know exactly why I prefer Python, but that's also subjective, and wouldn't help anybody choosing, as they might not have the same tastes in development as I do. It would therefore be interesting to list the differences, objectively. So no "Python's lambdas sucks". Instead explain what Ruby's lambdas can do that Python's can't. No subjectivity. Example code is good! Don't have several differences in one answer, please. And vote up the ones you know are correct, and down those you know are incorrect (or are subjective). Also, differences in syntax is not interesting. We know Python does with indentation what Ruby does with brackets and ends, and that @ is called self in Python. UPDATE: This is now a community wiki, so we can add the big differences here. Ruby has a class reference in the class body In Ruby you have a reference to the class (self) already in the class body. In Python you don't have a reference to the class until after the class construction is finished. An example: class Kaka puts self end self in this case is the class, and this code would print out "Kaka". There is no way to print out the class name or in other ways access the class from the class definition body in Python. All classes are mutable in Ruby This lets you develop extensions to core classes. Here's an example of a rails extension: class String def starts_with?(other) head = self[0, other.length] head == other end end Ruby has Perl-like scripting features Ruby has first class regexps, $-variables, the awk/perl line by line input loop and other features that make it more suited to writing small shell scripts that munge text files or act as glue code for other programs. Ruby has first class continuations Thanks to the callcc statement. In Python you can create continuations by various techniques, but there is no support built in to the language. Ruby has blocks With the "do" statement you can create a multi-line anonymous function in Ruby, which will be passed in as an argument into the method in front of do, and called from there. In Python you would instead do this either by passing a method or with generators. Ruby: amethod { |here| many=lines+of+code goes(here) } Python: def function(here): many=lines+of+code goes(here) amethod(function) Interestingly, the convenience statement in Ruby for calling a block is called "yield", which in Python will create a generator. Ruby: def themethod yield 5 end themethod do |foo| puts foo end Python: def themethod(): yield 5 for foo in themethod: print foo Although the principles are different, the result is strikingly similar. Python has built-in generators (which are used like Ruby blocks, as noted above) Python has support for generators in the language. In Ruby you could use the generator module that uses continuations to create a generator from a block. Or, you could just use a block/proc/lambda! Moreover, in Ruby 1.9 Fibers are, and can be used as, generators. docs.python.org has this generator example: def reverse(data): for index in range(len(data)-1, -1, -1): yield data[index] Contrast this with the above block examples. Python has flexible name space handling In Ruby, when you import a file with require, all the things defined in that file will end up in your global namespace. This causes namespace pollution. The solution to that is Rubys modules. But if you create a namespace with a module, then you have to use that namespace to access the contained classes. In Python, the file is a module, and you can import its contained names with from themodule import *, thereby polluting the namespace if you want. But you can also import just selected names with from themodule import aname, another or you can simply import themodule and then access the names with themodule.aname. If you want more levels in your namespace you can have packages, which are directories with modules and an __init__.py file. Python has docstrings Docstrings are strings that are attached to modules, functions and methods and can be introspected at runtime. This helps for creating such things as the help command and automatic documentation. def frobnicate(bar): """frobnicate takes a bar and frobnicates it >>> bar = Bar() >>> bar.is_frobnicated() False >>> frobnicate(bar) >>> bar.is_frobnicated() True """ Python has more libraries Python has a vast amount of available modules and bindings for libraries. Python has multiple inheritance Ruby does not ("on purpose" -- see Ruby's website, see here how it's done in Ruby). It does reuse the module concept as a sort of abstract classes. Python has list/dict comprehensions Python: res = [x*x for x in range(1, 10)] Ruby: res = (0..9).map { |x| x * x } Python: >>> (x*x for x in range(10)) <generator object <genexpr> at 0xb7c1ccd4> >>> list(_) [0, 1, 4, 9, 16, 25, 36, 49, 64, 81] Ruby: p = proc { |x| x * x } (0..9).map(&p) Python: >>> {x:str(y*y) for x,y in {1:2, 3:4}.items()} {1: '4', 3: '16'} Ruby: >> Hash[{1=>2, 3=>4}.map{|x,y| [x,(y*y).to_s]}] => {1=>"4", 3=>"16"} Python has decorators Things similar to decorators can be created in Ruby, and it can also be argued that they aren't as necessary as in Python.

  • Embedding mercurial revision information in Visual Studio c# projects automatically

    - by Mark Booth
    Original Problem In building our projects, I want the mercurial id of each repository to be embedded within the product(s) of that repository (the library, application or test application). I find it makes it so much easier to debug an application ebing run by custiomers 8 timezones away if you know precisely what went into building the particular version of the application they are using. As such, every project (application or library) in our systems implement a way of getting at the associated revision information. I also find it very useful to be able to see if an application has been compiled with clean (un-modified) changesets from the repository. 'Hg id' usefully appends a + to the changeset id when there are uncommitted changes in a repository, so this allows is to easily see if people are running a clean or a modified version of the code. My current solution is detailed below, and fulfills the basic requirements, but there are a number of problems with it. Current Solution At the moment, to each and every Visual Studio solution, I add the following "Pre-build event command line" commands: cd $(ProjectDir) HgID I also add an HgID.bat file to the Project directory: @echo off type HgId.pre > HgId.cs For /F "delims=" %%a in ('hg id') Do <nul >>HgID.cs set /p = @"%%a" echo ; >> HgId.cs echo } >> HgId.cs echo } >> HgId.cs along with an HgId.pre file, which is defined as: namespace My.Namespace { /// <summary> Auto generated Mercurial ID class. </summary> internal class HgID { /// <summary> Mercurial version ID [+ is modified] [Named branch]</summary> public const string Version = When I build my application, the pre-build event is triggered on all libraries, creating a new HgId.cs file (which is not kept under revision control) and causing the library to be re-compiled with with the new 'hg id' string in 'Version'. Problems with the current solution The main problem is that since the HgId.cs is re-created at each pre-build, every time we need to compile anything, all projects in the current solution are re-compiled. Since we want to be able to easily debug into our libraries, we usually keep many libraries referenced in our main application solution. This can result in build times which are significantly longer than I would like. Ideally I would like the libraries to compile only if the contents of the HgId.cs file has actually changed, as opposed to having been re-created with exactly the same contents. The second problem with this method is it's dependence on specific behaviour of the windows shell. I've already had to modify the batch file several times, since the original worked under XP but not Vista, the next version worked under Vista but not XP and finally I managed to make it work with both. Whether it will work with Windows 7 however is anyones guess and as time goes on, I see it more likely that contractors will expect to be able to build our apps on their Windows 7 boxen. Finally, I have an aesthetic problem with this solution, batch files and bodged together template files feel like the wrong way to do this. My actual questions How would you solve/how are you solving the problem I'm trying to solve? What better options are out there than what I'm currently doing? Rejected Solutions to these problems Before I implemented the current solution, I looked at Mercurials Keyword extension, since it seemed like the obvious solution. However the more I looked at it and read peoples opinions, the more that I came to the conclusion that it wasn't the right thing to do. I also remember the problems that keyword substitution has caused me in projects at previous companies (just the thought of ever having to use Source Safe again fills me with a feeling of dread *8'). Also, I don't particularly want to have to enable Mercurial extensions to get the build to complete. I want the solution to be self contained, so that it isn't easy for the application to be accidentally compiled without the embedded version information just because an extension isn't enabled or the right helper software hasn't been installed. I also thought of writing this in a better scripting language, one where I would only write HgId.cs file if the content had actually changed, but all of the options I could think of would require my co-workers, contractors and possibly customers to have to install software they might not otherwise want (for example cygwin). Any other options people can think of would be appreciated. Update Partial solution Having played around with it for a while, I've managed to get the HgId.bat file to only overwrite the HgId.cs file if it changes: @echo off type HgId.pre > HgId.cst For /F "delims=" %%a in ('hg id') Do <nul >>HgId.cst set /p = @"%%a" echo ; >> HgId.cst echo } >> HgId.cst echo } >> HgId.cst fc HgId.cs HgId.cst >NUL if %errorlevel%==0 goto :ok copy HgId.cst HgId.cs :ok del HgId.cst Problems with this solution Even though HgId.cs is no longer being re-created every time, Visual Studio still insists on compiling everything every time. I've tried looking for solutions and tried checking "Only build startup projects and dependencies on Run" in Tools|Options|Projects and Solutions|Build and Run but it makes no difference. The second problem also remains, and now I have no way to test if it will work with Vista, since that contractor is no longer with us. If anyone can test this batch file on a Windows 7 and/or Vista box, I would appreciate hearing how it went. Finally, my aesthetic problem with this solution, is even strnger than it was before, since the batch file is more complex and this there is now more to go wrong. If you can think of any better solution, I would love to hear about them.

  • Problem with jQuery and ASP.Net MVC 2

    - by robert_d
    I have a problem with jQuery, here is how my web app works Search.aspx web page which contains a form and jQuery script posts data to Search() action in Home controller after user clicks button1 button. Search.aspx: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<GLSChecker.Models.WebGLSQuery>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Title </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Search</h2> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm()) {%> <fieldset> <div class="editor-label"> <%: Html.LabelFor(model => model.Url) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Url, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Url) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Location) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Location, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Location) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.KeywordLines) %> </div> <div class="editor-field"> <%: Html.TextAreaFor(model => model.KeywordLines, 10, 60, null)%> <%: Html.ValidationMessageFor(model => model.KeywordLines)%> </div> <p> <input id ="button1" type="submit" value="Search" /> </p> </fieldset> <% } %> <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> jQuery("#button1").click(function (e) { window.setInterval(refreshResult, 5000); }); function refreshResult() { jQuery("#divResult").load("/Home/Refresh"); } </script> <div id="divResult"> </div> </asp:Content> [HttpPost] public ActionResult Search(WebGLSQuery queryToCreate) { if (!ModelState.IsValid) return View("Search"); queryToCreate.Remote_Address = HttpContext.Request.ServerVariables["REMOTE_ADDR"]; Session["Result"] = null; SearchKeywordLines(queryToCreate); Thread.Sleep(15000); return View("Search"); }//Search() After button1 button is clicked the above script from Search.aspx web page runs. Search() action in controller runs for longer period of time. I simulate this in testing by putting Thread.Sleep(15000); in Search()action. 5 sec. after Submit button was pressed, the above jQuery script calls Refresh() action in Home controller. public ActionResult Refresh() { ViewData["Result"] = DateTime.Now; return PartialView(); } Refresh() renders this partial <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" % <%= ViewData["Result"] % The problem is that in Internet Explorer 8 there is only one request to /Home/Refresh; in Firefox 3.6.3 all requests to /Home/Refresh are made but nothing is displayed on the web page. Another problem with Firefox is that requests to /Home/Refresh are made every second not every 5 seconds. I noticed that after I clear Firefox cache the script works well first time button1 is pressed, but after that it doesn't work. I would be grateful for helpful suggestions.

  • New hire expectations... (Am I being unreasonable?)

    - by user295841
    I work for a very small custom software shop. We currently consist me and my boss. My boss is an old FoxPro DOS developer and OOP makes him uncomfortable. He is planning on taking a back seat in the next few years to hopefully enjoy a “partial retirement”. I will be taking over the day to day operations and we are now desperately looking for more help. We tried Monster.com, Dice.com, and others a few years ago when we started our search. We had no success. We have tried outsourcing overseas (total disaster), hiring kids right out of college (mostly a disaster but that’s where I came from), interns (good for them, not so good for us) and hiring laid off “experienced” developers (there was a reason they were laid off). I have heard hiring practices discussed on podcasts, blogs, etc... and have tried a few. The “Fizz Buzz” test was a good one. One kid looked physically ill before he finally gave up. I think my problem is that I have grown so much as a developer since I started here that I now have a high standard. I hear/read very intelligent people podcasts and blogs and I know that there are lots of people out there that can do the job. I don’t want to settle for less than a “good” developer. Perhaps my expectations are unreasonable. I expect any good developer (entry level or experienced) to be billable (at least paying their own wage) in under one month. I expect any good developer to be able to be productive (at least dangerous) in any language or technology with only a few days of research/training. I expect any good developer to be able to take a project from initial customer request to completion with little or no help from others. Am I being unreasonable? What constitutes a valuable developer? What should be expected of an entry level developer? What should be expected of an experienced developer? I realize that everyone is different but there has to be some sort of expectations standard, right? I have been giving the test project below to potential canidates to weed them out. Good idea? Too much? Too little? Please let me know what you think. Thanks.

  • Linux C: "Interactive session" with separate read and write named pipes?

    - by ~sd-imi
    Hi all, I am trying to work with "Introduction to Interprocess Communication Using Named Pipes - Full-Duplex Communication Using Named Pipes", http://developers.sun.com/solaris/articles/named_pipes.html#5 ; in particular fd_server.c (included below for reference) Here is my info and compile line: :~$ cat /etc/issue Ubuntu 10.04 LTS \n \l :~$ gcc --version gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 :~$ gcc fd_server.c -o fd_server fd_server.c creates two named pipes, one for reading and one for writing. What one can do, is: in one terminal, run the server and read (through cat) its write pipe: :~$ ./fd_server & 2/dev/null [1] 11354 :~$ cat /tmp/np2 and in another, write (using echo) to server's read pipe: :~$ echo "heeellloooo" /tmp/np1 going back to first terminal, one can see: :~$ cat /tmp/np2 HEEELLLOOOO 0[1]+ Exit 13 ./fd_server 2 /dev/null What I would like to do, is make sort of a "interactive" (or "shell"-like) session; that is, the server is run as usual, but instead of running "cat" and "echo", I'd like to use something akin to screen. What I mean by that, is that screen can be called like screen /dev/ttyS0 38400, and then it makes a sort of a interactive session, where what is typed in terminal is passed to /dev/ttyS0, and its response is written to terminal. Now, of course, I cannot use screen, because in my case the program has two separate nodes, and as far as I can tell, screen can refer to only one. How would one go about to achieve this sort of "interactive" session in this context (with two separate read/write pipes)? Thanks, Cheers! Code below: #include <stdio.h> #include <errno.h> #include <ctype.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> //#include <fullduplex.h> /* For name of the named-pipe */ #define NP1 "/tmp/np1" #define NP2 "/tmp/np2" #define MAX_BUF_SIZE 255 #include <stdlib.h> //exit #include <string.h> //strlen int main(int argc, char *argv[]) { int rdfd, wrfd, ret_val, count, numread; char buf[MAX_BUF_SIZE]; /* Create the first named - pipe */ ret_val = mkfifo(NP1, 0666); if ((ret_val == -1) && (errno != EEXIST)) { perror("Error creating the named pipe"); exit (1); } ret_val = mkfifo(NP2, 0666); if ((ret_val == -1) && (errno != EEXIST)) { perror("Error creating the named pipe"); exit (1); } /* Open the first named pipe for reading */ rdfd = open(NP1, O_RDONLY); /* Open the second named pipe for writing */ wrfd = open(NP2, O_WRONLY); /* Read from the first pipe */ numread = read(rdfd, buf, MAX_BUF_SIZE); buf[numread] = '0'; fprintf(stderr, "Full Duplex Server : Read From the pipe : %sn", buf); /* Convert to the string to upper case */ count = 0; while (count < numread) { buf[count] = toupper(buf[count]); count++; } /* * Write the converted string back to the second * pipe */ write(wrfd, buf, strlen(buf)); } Edit: Right, just to clarify - it seems I found a document discussing something very similar, it is http://en.wikibooks.org/wiki/Serial_Programming/Serial_Linux#Configuration_with_stty - a modification of the script there ("For example, the following script configures the device and starts a background process for copying all received data from the serial device to standard output...") for the above program is below: # stty raw # ( ./fd_server 2>/dev/null; )& bgPidS=$! ( cat < /tmp/np2 ; )& bgPid=$! # Read commands from user, send them to device echo $(kill -0 $bgPidS 2>/dev/null ; echo $?) while [ "$(kill -0 $bgPidS 2>/dev/null ; echo $?)" -eq "0" ] && read cmd; do # redirect debug msgs to stderr, as here we're redirected to /tmp/np1 echo "$? - $bgPidS - $bgPid" >&2 echo "$cmd" echo -e "\nproc: $(kill -0 $bgPidS 2>/dev/null ; echo $?)" >&2 done >/tmp/np1 echo OUT # Terminate background read process - if they still exist if [ "$(kill -0 $bgPid 2>/dev/null ; echo $?)" -eq "0" ] ; then kill $bgPid fi if [ "$(kill -0 $bgPidS 2>/dev/null ; echo $?)" -eq "0" ] ; then kill $bgPidS fi # stty cooked So, saving the script as say starter.sh and calling it, results with the following session: $ ./starter.sh 0 i'm typing here and pressing [enter] at end 0 - 13496 - 13497 I'M TYPING HERE AND PRESSING [ENTER] AT END 0~?.N=?(?~? ?????}????@??????~? [garble] proc: 0 OUT which is what I'd call for "interactive session" (ignoring the debug statements) - server waits for me to enter a command; it gives its output after it receives a command (and as in this case it exits after first command, so does the starter script as well). Except that, I'd like to not have buffered input, but sent character by character (meaning the above session should exit after first key press, and print out a single letter only - which is what I expected stty raw would help with, but it doesn't: it just kills reaction to both Enter and Ctrl-C :) ) I was just wandering if there already is an existing command (akin to screen in respect to serial devices, I guess) that would accept two such named pipes as arguments, and establish a "terminal" or "shell" like session through them; or would I have to use scripts as above and/or program own 'client' that will behave as a terminal..

  • Javascript: selfmade methods not working correctly

    - by hdr
    Hi everyone, I tried to figure this out for some days now, I tried to use my own object to sort of replace the global object to reduce problems with other scripts (userscripts, chrome extensions... that kind of stuff). However I can't get things to work for some reason. I tried some debugging with JSLint, the developer tools included in Google Chrome, Firebug and the integrated schript debugger in IE8 but there is no error that explains why it doesn't work at all in any browser I tried. I tried IE 8, Google Chrome 10.0.612.3 dev, Firefox 3.6.13, Safari 5.0.3 and Opera 11. So... here is the code: HTML: <!DOCTYPE HTML> <html manifest="c.manifest"> <head> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta charset="utf-8"> <!--[if IE]> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/chrome-frame/1/CFInstall.min.js"></script> <script src="https://ie7-js.googlecode.com/svn/version/2.1(beta4)/IE9.js">IE7_PNG_SUFFIX=".png";</script> <![endif]--> <!--[if lt IE 9]> <script src="js/lib/excanvas.js"></script> <script src="https://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> <script src="js/data.js"></script> </head> <body> <div id="controls"> <button onclick="MYOBJECTis.next()">Next</button> </div> <div id="textfield"></div> <canvas id="game"></canvas> </body> </html> Javascript: var that = window, it = document, k = Math.floor; var MYOBJECTis = { aresizer: function(){ // This method looks like it doesn't work. // It should automatically resize all the div elements and the body. // JSLint: no error (execpt for "'window' is not defined." which is normal since // JSLint does nor recognize references to the global object like "window" or "self" // even if you assume a browser) // Firebug: no error // Chrome dev tools: no error // IE8: that.documentElement.clientWidth is null or not an object "use strict"; var a = that.innerWidth || that.documentElement.clientWidth, d = that.innerHeight || that.documentElement.clientHeight; (function() { for(var b = 0, c = it.getElementsByTagName("div");b < c.length;b++) { c.style.width = k(c.offsetWidth) / 100 * k(a); c.style.height = k(c.offsetHight) / 100 * k(d); } }()); (function() { var b = it.getElementsByTagName("body"); b.width = a; b.height = d; }()); }, next: function(){ // This method looks like it doesn't work. // It should change the text inside a div element // JSLint: no error (execpt for "'window' is not defined.") // Firebug: no error // Chrome dev tools: no error // IE8: no error (execpt for being painfully slow) "use strict"; var b = it.getElementById("textfield"), a = [], c; switch(c !== typeof Number){ case true: a[1] = ["HI"]; c = 0; break; case false: return Error; default: b.innerHtml = a[c]; c+=1; } } }; // auto events (function(){ "use strict"; that.onresize = MYOBJECTis.aresizer(); }()); If anyone can help me out with this I would very much appreciate it. EDIT: To answer the question what's not working I can just say that no method I showed here is working at all and I don't know the cause of the problem. I also tried to clean up some of the code that has most likely nothing to do with it. Additional information is in the comments inside the code.

  • Understanding the passing of data/life of a script in web development/CodeIgniter

    - by Pete Jodo
    I hope I worded the title accurately enough but I typically use Java and don't have much experience in Web Development/PHP/CodeIgniter. I have a difficult time understanding the life cycle of a script as I found out trying to implement a certain feature to a website I am developing (as a means of learning how to). I'll first describe the feature I tried implementing and then the problem I ran into that made me question my fundamental understanding of how scripts work since I'm used to typical OOP. Ok so here goes... I have a webpage that has 2 basic tasks a user can do, create and delete an entry. What I attempted to implement was a way to time a user how long it takes them to complete a certain task. The way I did this was have a homepage where there would be a list of tasks a user to choose from (in this case 2, create and delete). A user would click a task which would link to the 'true' homepage where the user then would be expected to complete the task. My script looks like this: <?php class Site extends CI_Controller { var $task1; var $tasks = array( "task1" => NULL, "date1" => 0, "date2" => 0, "diff" => 0); function __construct() { parent::__construct(); include 'timetask.php'; $this->task1 = new TimeTask("create"); } function index() { $this->tasks['task1'] = $this->task1->getTask(); $this->tasks['diff'] = $this->task1->getTimeDiff(); if($this->tasks['diff'] == NULL) { $this->tasks['diff'] = 0; } $this->load->view('usability_test', $this->tasks); } function origIndex() { $this->task1->setDate1(new DateTime()); $this->tasks['date1'] = $this->task1->getDate1()->getTimestamp(); $data = array(); if($q = $this->site_model->get_records()) { $data['records'] = $q; } $this->load->view('options_view', $data); } function create() { $this->task1->setDate2(new DateTime()); $this->tasks['date2'] = $this->task1->getDate2()->getTimestamp(); $data = array( 'author' => $this->input->post('author'), 'title' => $this->input->post('title'), 'contents' => $this->input->post('contents') ); $this->site_model->add_record($data); $this->index(); } I only included create to keep it short. Then I also have the TimeTask class, that actually another StackOverflow so kindly helped me with: <?php class TimeTask { private $task; /** * @var DateTime */ private $date1, $date2; function __construct($currTask) { $this->task = $currTask; } public function getTimeDiff() { $hasDiff = $this->date1 && $this->date2; if ($hasDiff) { return $this->date2->getTimestamp() - $this->date1->getTimestamp(); } else { return NULL; } } public function __toString() { return (string) $this->getTimeDiff(); } /** * @return \DateTime */ public function getDate1() { return $this->date1; } /** * @param \DateTime $date1 */ public function setDate1(DateTime $date1) { $this->date1 = $date1; } /** * @return \DateTime */ public function getDate2() { return $this->date2; } /** * @param \DateTime $date2 */ public function setDate2(DateTime $date2) { $this->date2 = $date2; } /** * @return get current task */ public function getTask() { return $this->task; } } ?> I don't think posting the views is necessary for the question but here is atleast how the links are made. ...and... id", $row-title); ? Now there's no error in the code but it doesn't do what I expect of it and the reason I assume why is because that each time a function of the script is called via a new page it is NOT the same instance of the script called previously so any previously created objects are no longer there. This confuses me and leaves me quite unsure of how to implement this gracefully. Some ways I would guess of how to do this is by passing the necessary data through the URL or have data saved in a database and retrieve it later to compare the times. What would be a recommended way to do, not just this, but anything that needs previously created data? Also, am I correct to think that a script is only 'alive' for one webpage at a time? Thanks!

  • Help with understanding why UAC dialog pops up on Win7 for our application

    - by Tim
    We have a C++ unmanaged application that appears to cause a UAC prompt. It seems to happen on Win7 and NOT on Vista Unfortunately the UAC dlg is system modal so I can't attach a debugger to check in the code where it is, and running under msdev (we're using 2008) runs in elevated mode. We put a message box at the start of our program/winmain but it doesn't even get that far, so apparently this is in the startup code. What can cause a UAC notification so early and what other things can I do to track down the cause? EDIT Apparently the manifest is an important issue here, but it seems not to be helping me - or perhaps I am not configuring the manifest file correctly. Can someone provide a sample manifest? Also, does the linker/UAC magic figure out that the program "might" write to the registry and set its UAC requirements based on that? There are code paths that might trigger UAC, but we are not even at that point when the UAC dlg comes up. An additional oddity is that this does not seem to happen on Vista with UAC turned on. Here is a manifest (that I think is/was generated automatically): <?xml version='1.0' encoding='UTF-8' standalone='yes'?> <assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level='asInvoker' uiAccess='false' /> </requestedPrivileges> </security> </trustInfo> <dependency> <dependentAssembly> <assemblyIdentity type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*' /> </dependentAssembly> </dependency> <dependency> <dependentAssembly> <assemblyIdentity type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*' /> </dependentAssembly> </dependency> </assembly> And then this one was added to the manifest list to see if it would help <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0" processorArchitecture="x86" name="[removed for anonymity]" type="win32" /> <description> [removed for anonymity] </description> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="x86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> <security> <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="false"/> </requestedPrivileges> </security> </trustInfo> </assembly> The following is from the actual EXE using the ManifestViewer tool - <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0" processorArchitecture="x86" name="[removed]" type="win32" /> <description>[removed]</description> - <dependency> - <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="x86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> - <dependency> - <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="*" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> - <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> - <security> - <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="false" /> </requestedPrivileges> </security> </trustInfo> </assembly> It appears that it might be due to the xp compatibility setting on our app. I'll have to test that. (we set that in the installer I found out because some sound drivers don't work correctly on win7)

  • IE 8 Automatically Closing <header> tag

    - by djthoms
    Background I am currently working on the final QA of a responsive website and I'm having an issue with IE 8 and IE 7. My client deals with government contracting so their website needs to be compatible with IE 8 and IE 7. I am using Modernizr with html5shiv built in. I am loading Modernizr in the footer of a WordPress theme that was custom built for this project. I'm not missing a doctype or any other obvious code. I am using the following scripts, all of which are loaded in the footer of WordPress: jQuery 1.10.1 Modernizr 2.6.3 (click for config) respond.js 1.3.0 superfish jQuery Waypoints 2.0.3 jQuery Waypoints Sticky 2.0.3 The Situation I'm having an issue with IE 8 automatically closing a <header> tag. First, I have used two utilities to check this issue: IETester IE 11 emulated to IE 8 w/ IE 8 User agent Here is the correct output <div class="wrapper main-header"> <header class="container"> <div class="sixteen columns alpha omega"> <div class="eight columns alpha omega logo"> <a href="http://example.com"><img src="http://example.com/wp-content/uploads/2013/10/logo.png" alt="Example"></a> </div> <div class="wrapper main-navigation desktop"> <nav id="nav" class="six columns alpha omega"> ... </nav> <div class="eight columns alpha omega overlay" style="display: none;"> ... </div> <div class="two columns alpha omega menu-ss"> ... </div> </div><!-- .wrapper.main-navigation --> </div><!-- /.sixteen.columns --> </header><!--/header--> </div><!-- /.main-header --> What IE 8 is rendering: <div class="wrapper main-header"> <header class="container"></header> <div class="sixteen columns alpha omega"> <div class="eight columns alpha omega logo"> <a href="http://example.com"><img src="http://example.com/wp-content/uploads/2013/10/logo.png" alt="Example"></a> </div> <div class="wrapper main-navigation desktop"> <nav id="nav" class="six columns alpha omega"> ... </nav> <div class="eight columns alpha omega overlay" style="display: none;"> ... </div> <div class="two columns alpha omega menu-ss"> ... </div> </div><!-- .wrapper.main-navigation --> </div><!-- /.sixteen.columns --> </header><//header><!--/header--> </div><!-- /.main-header --> What I have Tried Loading html5shiv with IE conditional in the <head> Loading Modernizr in the <head> I have looked at these Stackoverflow questions/answers: html 5 tags foorter or header in ie 8 and ie 7 html5 not rendering header tags in ie IE 8 self closing tags automatically Any assistance with this is greatly appreciated! I would really really really like to finish this website over the weekend. I've been banging my head against a wall for the past few hours over this issue. Update Here are some images from browsershack to cut out the emulation. I tested the site virtually with Windows 7 and WIndows XP (IE 8 & IE 7). http://www.browserstack.com/screenshots/0d7c1d6dd22927c20495e67f07afe8934957b4d1

  • CSS issue with margin: auto

    - by user1702273
    Hi am having an issue with the margin auto of my website where i have a wrapper div with the width set to 1000px and the margins top and bottom to 0 and left and right to auto. I have a navigation menu in the side bar, where i used java script to replace the same div with different tables. when i click a link in the menu the wrapper shifts right some px and the comes to original, I don't want that action i want the wrapper to be static and not to vary at any time. how can i achieve that. when i set the margin to just 0, so problem with positioning. But i want the wrapper to be centered. Here is my css code: body { background-color:#E2E3E4; color:#333; margin:0; padding:0; font-size: 12px; } #wrapper { width:1000px; margin:0 auto; margin-bottom:10px; } #header1 { width:1000px; height:44px; margin:0 auto; background-color:#ED6B06; } #header2 { width:1000px; height:40px; margin:0 auto; border-bottom:1px solid #EDE9DE; } #header3 { width:1000px; height:40px; margin:0 auto; border-bottom:1px solid #EDE9DE; } #header2 p { margin:0 auto; font-size:20pt; color: #364395; font-smooth: auto; margin-left:15px; margin-top:5px; } #welcome { width:600px; float:left; padding:10px; margin:0 auto; } #status{ margin:0 auto; width:50px; float:right; padding:10px; margin-top:3px; margin-right:15px; } #content { width:780px; float:right; } #sidebar { width:150px; margin-top:15px; margin-left:10px; float:left; border-right:1px solid #EDE9DE; margin-bottom:25px; } #footer { clear:both; margin:0 auto; width:1000px; height:44px; border-top:1px solid #EDE9DE; } HTML: <html> <head> <link rel="stylesheet" type="text/css" href="style/style.css" media="screen" /> <title>Pearson Schools Management Portal</title> </head> <body id="home"> <div id="wrapper"> <?php include('includes/header1.php'); ?> <?php include('includes/header2.php'); ?> <?php include('includes/header3.php'); ?> <div id="content"> <h2>Welcome to Portal!</h2> </div> <!-- end #content --> <?php include('includes/sidebar.php'); ?> <?php include('includes/footer.php'); ?> </div> <!-- End #wrapper --> <link rel="stylesheet" type="text/css" media="screen" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/base/jquery-ui.css"> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript" src="http://jzaefferer.github.com/jquery-validation/jquery.validate.js"></script> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"></script> <?php include('scripts/index_data.js'); ?> </body>
