  • Consuming OData based Rest service in C# [en-US]

    - by ruimachado
    Nowadays comunication between applications is an active topic with daily usage and a large amount of pratical appliances. While developing an app in witch I had to consume an OData I found out that combining Linq with my code made this operation pretty easy.The algorithm to consume OData starts with adding a service reference to Visual Studio:After adding the service reference in wich you define the uri to the service, we start building our code.In your code the algorithm is the following:Define the Uri to your OData ServiceDefine the context of your odata, wich contains all entities exposed by the service.Query the context using LinqPrint the resultEasy and simple.Example code:01public static void Main(string[] args){02 03        Uri serviceUri= newUri("http://example.host.odataservice.net/service.svc", UriKind.Absolute);04        ODataService.ServiceEntities context = newODataService.ServiceEntities (serviceUri);05 06        context.Credentials = newSystem.Net.NetworkCredential(Username,Password);07 08         var query = from ServiceObject in context.YourEntity09                     select ServiceObject ;10 11        foreach (var myObject in query)12        {13            Console.WriteLine("\n Field1: {0} | Field2: {1}",14            myObject .Field1, myObject .Field2);15 16        }17}That’s it.Thank you,Rui Machadorpmachado.wordpress.com

  • JQuery Validation [migrated]

    - by user41354
    Im trying to get my form to validate...so basically its working, but a little bit too well, I have two text boxes, one is a start date, the other an end date in the format of mm/dd/yyyy if the start date is greater than the end date...there is an error if the end date is less than the start date...there is an error if the start date is less than today's date...there is an error The only thing is when I correct the error, the error warning is still there...here is my code: dates.change(function () { var testDate = $(this).val(); var otherDate = dates.not(this).val(); var now = new Date(); now.setHours(0, 0, 0, 0); // Pass Dates if (testDate != '' && new Date(testDate) < now) { addError($(this)); $('.flightDateError').text('* Dates cannot be earlier than today.'); isValid = false; return; } // Required Text if ($(this).hasClass("FromCal") && testDate == '') { addError($(this)); $('.flightDateError').text('* Required'); isValid = false; return; } // Validate Date if (!isValidDate(testDate)) { // $(this).addClass('validation_error_input'); addError($(this)); $('.flightDateError').text('* Invalid Date'); isValid = false; return; } else { // $(this).removeClass('validation_error_input'); removeError($(this)); if (!dates.not(this).hasClass('validation_error_input')) $('.flightDateError').text(' '); } // Validate Date Ranges if ($(this).val() != '' && dates.not(this).val != '') { if ($(this).hasClass("FromCal")) { if (new Date(testDate) > new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* Start date must be earlier than end date.'); isValid = false; return; } } else{ if (new Date(testDate) < new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* End date must be later than start date.'); return; } } } }); The main Issue is this part, I believe // Validate Date Ranges if ($(this).val() != '' && dates.not(this).val != '') { if ($(this).hasClass("FromCal")) { if (new Date(testDate) > new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* Start date must be earlier than end date.'); isValid = false; return; } } else{ if (new Date(testDate) < new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* End date must be later than start date.'); return; } } } testDate is the start date otherDate is the end date Thanks in advanced, J

  • Removing the last digits in string [migrated]

    - by Ruriko
    I have a string that looks like this: [APPLE PIE] Sei Shoujo Sentai Lakers 3 Battle Team Lakers 3 (100% FULL-PIC)_20121104_032834 I want to remove the digits at the end of the string, basically the 16 digits at the end of the string. In the end it should look like this: [APPLE PIE] Sei Shoujo Sentai Lakers 3 Battle Team Lakers 3 (100% FULL-PIC) This is my code that I have written so far var str="[APPLE PIE] Sei Shoujo Sentai Lakers 3 Battle Team Lakers 3 (100% FULL-PIC)_20121104_032834"; var n=str.substr(1,74); document.write(n); The problem is the string will be different so each will have different amount of characters. So how I remove the digits at the end of the string in javascript?

  • How to fix basicHttpBinding in WCF when using multiple proxy clients?

    - by Hemant
    [Question seems a little long but please have patience. It has sample source to explain the problem.] Consider following code which is essentially a WCF host: [ServiceContract (Namespace = "http://www.mightycalc.com")] interface ICalculator { [OperationContract] int Add (int aNum1, int aNum2); } [ServiceBehavior (InstanceContextMode = InstanceContextMode.PerCall)] class Calculator: ICalculator { public int Add (int aNum1, int aNum2) { Thread.Sleep (2000); //Simulate a lengthy operation return aNum1 + aNum2; } } class Program { static void Main (string[] args) { try { using (var serviceHost = new ServiceHost (typeof (Calculator))) { var httpBinding = new BasicHttpBinding (BasicHttpSecurityMode.None); serviceHost.AddServiceEndpoint (typeof (ICalculator), httpBinding, "http://172.16.9.191:2221/calc"); serviceHost.Open (); Console.WriteLine ("Service is running. ENJOY!!!"); Console.WriteLine ("Type 'stop' and hit enter to stop the service."); Console.ReadLine (); if (serviceHost.State == CommunicationState.Opened) serviceHost.Close (); } } catch (Exception e) { Console.WriteLine (e); Console.ReadLine (); } } } Also the WCF client program is: class Program { static int COUNT = 0; static Timer timer = null; static void Main (string[] args) { var threads = new Thread[10]; for (int i = 0; i < threads.Length; i++) { threads[i] = new Thread (Calculate); threads[i].Start (null); } timer = new Timer (o => Console.WriteLine ("Count: {0}", COUNT), null, 1000, 1000); Console.ReadLine (); timer.Dispose (); } static void Calculate (object state) { var c = new CalculatorClient ("BasicHttpBinding_ICalculator"); c.Open (); while (true) { try { var sum = c.Add (2, 3); Interlocked.Increment (ref COUNT); } catch (Exception ex) { Console.WriteLine ("Error on thread {0}: {1}", Thread.CurrentThread.Name, ex.GetType ()); break; } } c.Close (); } } Basically, I am creating 10 proxy clients and then repeatedly calling Add service method on separate threads. Now if I run both applications and observe opened TCP connections using netstat, I find that: If both client and server are running on same machine, number of tcp connections are equal to number of proxy objects. It means all requests are being served in parallel. Which is good. If I run server on a separate machine, I observed that maximum 2 TCP connections are opened regardless of the number of proxy objects I create. Only 2 requests run in parallel. It hurts the processing speed badly. If I switch to net.tcp binding, everything works fine (a separate TCP connection for each proxy object even if they are running on different machines). I am very confused and unable to make the basicHttpBinding use more TCP connections. I know it is a long question, but please help!

  • Dojox grid having problem with Contentpane

  • Windows CE Programming Serial Port - Getting Garbled Output

    - by user576639
    I am programming a Windows CE 6 device (Motorola MC3100 scanner Terminal). Using Lazarus FPC to compile it. After 3 weeks work I reluctantly post here in the hope someone can suggest why I am getting garbled output from the serial port. The code I am using is posted below. This is the standard code I have found from several places. The OpenPort works OK. When I send the string using SendString('ABCDEF') I get garbled input to the PC Serial port such as: 4[#131][#26][#0][#0][#0][#0] (the bracketed data indicates that it is a non-printable character ASCII Code) Obviously it is connecting to the port OK AND it is sending the correct no of characters (7). I have tried all combinations of Baud Rate, Data Bits, Parity and Stop Bits without any joy. Also tried changing cable, on a different PC etc. Could it be I need to set something else in the DCB? Any help or suggestions would be GREATLY appreciated. unit Unit1; {$mode objfpc}{$H+} interface uses Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls, ExtCtrls, Windows, LResources; type { TForm1 } TForm1 = class(TForm) Button1: TButton; Button2: TButton; Label1: TLabel; procedure Button1Click(Sender: TObject); procedure Button2Click(Sender: TObject); function OpenPort(ComPort:String;BaudRate,ByteSize,Parity,StopBits:integer):String; procedure SendString(str:String); private { private declarations } public { public declarations } end; var Form1: TForm1; cc:TCOMMCONFIG; Connected:Boolean; implementation {$R *.lfm} var F: TextFile; var hComm: THandle; str: String; lrc: LongWord; { TForm1 } function OpenPort(ComPort:String;BaudRate,ByteSize,Parity,StopBits:integer):String; var cc:TCOMMCONFIG; SWide:WideString; Port:LPCWSTR; begin SWide:=ComPort; Port:=PWideChar(SWide); result:=''; if (1=1) then begin Connected:=False; hComm:=CreateFile(Port, GENERIC_READ or GENERIC_WRITE,0, nil,OPEN_EXISTING,0,0); if (hComm = INVALID_HANDLE_VALUE) then begin ShowMessage('Fail to Open'); exit; end; GetCommState(hComm,cc.dcb); cc.dcb.BaudRate:=BaudRate; cc.dcb.ByteSize:=ByteSize; cc.dcb.Parity:=Parity; cc.dcb.StopBits:=StopBits; if not SetCommState(hComm, cc.dcb) then begin result:='SetCommState Error!'; CloseHandle(hComm); exit; end; Connected:=True; end; end; procedure TForm1.Button1Click(Sender: TObject); begin OpenPort('COM1:',9600,8,0,0); end; procedure TForm1.Button2Click(Sender: TObject); begin SendString('ABCDEFG'); end; procedure TForm1.SendString(str:String); var lrc:LongWord; begin if (hComm=0) then exit; try if not PurgeComm(hComm, PURGE_TXABORT or PURGE_TXCLEAR) then raise Exception.Create('Unable to purge com: '); except Exit; end; WriteFile(hComm,str,Length(str), lrc, nil); end; end.

  • RegLoadAppKey working fine on 32-bit OS, failing on 64-bit OS, even if both processes are 32-bit

    - by James Manning
    I'm using .NET 4 and the new RegistryKey.FromHandle call so I can take the hKey I get from opening a registry file with RegLoadAppKey and operate on it with the existing managed API. I thought at first it was just a matter of a busted DllImport and my call had an invalid type in the params or a missing MarshalAs or whatever, but looking at other registry functions and their DllImport declarations (for instance, on pinvoke.net), I don't see what else to try (I've had hKey returned as both int and IntPtr, both worked on 32-bit OS and fail on 64-bit OS) I've got it down to as simple a repro case as I can - it just tries to create a 'random' subkey then write a value to it. It works fine on my Win7 x86 box and fails on Win7 x64 and 2008 R2 x64, even when it's still a 32-bit process, even run from a 32-bit cmd prompt. EDIT: It also fails in the same way if it's a 64-bit process. on Win7 x86: INFO: Running as Admin in 32-bit process on 32-bit OS Was able to create Microsoft\Windows\CurrentVersion\RunOnceEx\a95b1bbf-7a04-4707-bcca-6aee6afbfab7 and write a value under it on Win7 x64, as 32-bit: INFO: Running as Admin in 32-bit process on 64-bit OS Unhandled Exception: System.UnauthorizedAccessException: Access to the registry key '\Microsoft\Windows\CurrentVersion\RunOnceEx\ce6d5ff6-c3af-47f7-b3dc-c5a1b9a3cd22' is denied. at Microsoft.Win32.RegistryKey.Win32Error(Int32 errorCode, String str) at Microsoft.Win32.RegistryKey.CreateSubKeyInternal(String subkey, RegistryKeyPermissionCheck permissionCheck, Object registrySecurityObj, RegistryOptions registryOptions) at Microsoft.Win32.RegistryKey.CreateSubKey(String subkey) at LoadAppKeyAndModify.Program.Main(String[] args) on Win7 x64, as 64-bit: INFO: Running as Admin in 64-bit process on 64-bit OS Unhandled Exception: System.UnauthorizedAccessException: Access to the registry key '\Microsoft\Windows\CurrentVersion\RunOnceEx\43bc857d-7d07-499c-8070-574d6732c130' is denied. at Microsoft.Win32.RegistryKey.Win32Error(Int32 errorCode, String str) at Microsoft.Win32.RegistryKey.CreateSubKeyInternal(String subkey, RegistryKeyPermissionCheck permissionCheck, Object registrySecurityObj, RegistryOptions registryOptions) at Microsoft.Win32.RegistryKey.CreateSubKey(String subkey, RegistryKeyPermissionCheck permissionCheck) at LoadAppKeyAndModify.Program.Main(String[] args) source: class Program { static void Main(string[] args) { Console.WriteLine("INFO: Running as {0} in {1}-bit process on {2}-bit OS", new WindowsPrincipal(WindowsIdentity.GetCurrent()).IsInRole(WindowsBuiltInRole.Administrator) ?

  • What is the reason of "Transaction context in use by another session"

    - by Shrike
    Hi, I'm looking for a description of the root of this error: "Transaction context in use by another session". I get it sometimes in one of my unittests so I can't provider repro code. But I wonder what is "by design" reason for the error. I've found this post: http://blogs.msdn.com/asiatech/archive/2009/08/10/system-transaction-may-fail-in-multiple-thread-environment.aspx and also that: http://msdn.microsoft.com/en-us/library/ff649002.aspx But I can't understand what "Multiple threads sharing the same transaction in a transaction scope will cause the following exception: 'Transaction context in use by another session.' " means. All words are understandable but not the point. I actually can share a system transaction between threads. And there is even special mechanism for this - DependentTransaction class and Transaction.DependentClone method. I'm trying to reproduce a usecase from the first post: 1. Main thread creates DTC transaction, receives DependentTransaction (created using Transaction.Current.DependentClone on the main thread 2. Child thread 1 enlists in this DTC transaction by creating a transaction scope based on the dependent transaction (passed via constructor) 3. Child thread 1 opens a connection 4. Child thread 2 enlists in DTC transaction by creating a transaction scope based on the dependent transaction (passed via constructor) 5. Child thread 2 opens a connection with such code: using System; using System.Threading; using System.Transactions; using System.Data; using System.Data.SqlClient; public class Program { private static string ConnectionString = "Initial Catalog=DB;Data Source=.;User ID=user;PWD=pwd;"; public static void Main() { int MAX = 100; for(int i =0; i< MAX;i++) { using(var ctx = new TransactionScope()) { var tx = Transaction.Current; // make the transaction distributed using (SqlConnection con1 = new SqlConnection(ConnectionString)) using (SqlConnection con2 = new SqlConnection(ConnectionString)) { con1.Open(); con2.Open(); } showSysTranStatus(); DependentTransaction dtx = Transaction.Current.DependentClone(DependentCloneOption.BlockCommitUntilComplete); Thread t1 = new Thread(o => workCallback(dtx)); Thread t2 = new Thread(o => workCallback(dtx)); t1.Start(); t2.Start(); t1.Join(); t2.Join(); ctx.Complete(); } trace("root transaction completes"); } } private static void workCallback(DependentTransaction dtx) { using(var txScope1 = new TransactionScope(dtx)) { using (SqlConnection con2 = new SqlConnection(ConnectionString)) { con2.Open(); trace("connection opened"); showDbTranStatus(con2); } txScope1.Complete(); } trace("dependant tran completes"); } private static void trace(string msg) { Console.WriteLine(Thread.CurrentThread.ManagedThreadId + " : " + msg); } private static void showSysTranStatus() { string msg; if (Transaction.Current != null) msg = Transaction.Current.TransactionInformation.DistributedIdentifier.ToString(); else msg = "no sys tran"; trace( msg ); } private static void showDbTranStatus(SqlConnection con) { var cmd = con.CreateCommand(); cmd.CommandText = "SELECT 1"; var c = cmd.ExecuteScalar(); trace("@@TRANCOUNT = " + c); } } It fails on Complete's call of root TransactionScope. But error is different: Unhandled Exception: System.Transactions.TransactionInDoubtException: The transaction is in doubt. --- pired. The timeout period elapsed prior to completion of the operation or the server is not responding. To sum up: I want to understand what "Transaction context in use by another session" means and how to reproduce it.

  • AppDomain dependencies across directories

    - by strager
    I am creating a plugin system and I am creating one AppDomain per plugin. Each plugin has its own directory with its main assemblies and references. The main assemblies will be loaded by my plugin loader, in addition to my interface assemblies (so the plugin can interact with the application). Creating the AppDomain: this.appDomain = AppDomain.CreateDomain("AppDomain", null, new AppDomainSetup { ApplicationBase = pluginPath, PrivateBinPath = pluginPath, }); Loading the assemblies: this.appDomain.Load(myInterfaceAssembly.GetName(true)); var assemblies = new List<Assembly>(); foreach (var assemblyName in this.assemblyNames) { assemblies.Add(this.appDomain.Load(assemblyName)); } The format of assemblyName is the assembly's filename without ".dll". The problem is that AppDomain.Load(assemblyName) throws an exception: Could not load file or assembly '[[assemblyName]], Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. All of the dependencies of [[assemblyName]] are: Inside the directory pluginPath, The myInterfaceAssembly which is already loaded, or In the GAC (e.g. mscorelib). Clearly I'm not doing something right. I have tried: Creating an object using this.appDomain.CreateInstanceAndUnwrap inheriting from MarshalByRefObject with a LoadAssembly method to load the assembly. I get an exception saying that the current assembly (containing the proxy class) could not be loaded (file not found, as above), even if I manually call this.appDomain.Load(Assembly.GetExecutingAssembly().GetName(true)). Attaching an AssemblyResolve handler to this.appDomain. I'm met with the same exception as in (1), and manually loading doesn't help. Recursively loading assemblies by loading their dependencies into this.appDomain first. This doesn't work, but I doubt my code is correct: private static void LoadAssemblyInto(AssemblyName assemblyName, AppDomain appDomain) { var assembly = Assembly.Load(assemblyName); foreach (var referenceName in assembly.GetReferencedAssemblies()) { if (!referenceName.FullName.StartsWith("MyProject")) { continue; } var loadedAssemblies = appDomain.GetAssemblies(); if (loadedAssemblies.Any((asm) => asm.FullName == referenceName.FullName)) { continue; } LoadAssemblyInto(referenceName, appDomain); } appDomain.Load(assembly.GetName(true)); } How can I load my plugin assembly with its dependencies in that plugin's directory while also loading some assemblies in the current directory? Note: The assemblies a plugin may (probably will) reference are already loaded in the current domain. This can be shared across domains (performance benefit? simplicity?) if required.

  • jQuery sequence and function call problem

    - by Jonas
    Hi everyone, I'm very new to jquery and programming in general but I'm still trying to achieve something here. I use Fullcalendar to allow the users of my web application to insert an event in the database. The click on a day, view changes to agendaDay, then on a time of the day, and a dialog popup opens with a form. I am trying to combine validate (pre-jquery.1.4), jquery.form to post the form without page refresh The script calendar.php, included in several pages, defines the fullcalendar object and displays it in a div: $(document).ready(function() { function EventLoad() { $("#addEvent").validate({ rules: { calendar_title: "required", calendar_url: { required: false, maxlength: 100, url: true } }, messages: { calendar_title: "Title required", calendar_url: "Invalid URL format" }, success: function() { $('#addEvent').submit(function() { var options = { success: function() { $('#eventDialog').dialog('close'); $('#calendar').fullCalendar( 'refetchEvents' ); } }; // submit the form $(this).ajaxSubmit(options); // return false to prevent normal browser submit and page navigation return false; }); } }); } $('#calendar').fullCalendar({ header: { left: 'prev,next today', center: 'title', right: 'month,agendaWeek,agendaDay' }, theme: true, firstDay: 1, editable: false, events: "json-events.php?list=1&<?php echo $events_list; ?>", <?php if($_GET['page'] == 'home') echo "defaultView: 'agendaWeek',"; ?> eventClick: function(event) { if (event.url) { window.open(event.url); return false; } }, dayClick: function(date, allDay, jsEvent, view) { if (view.name == 'month') { $('#calendar').fullCalendar( 'changeView', 'agendaDay').fullCalendar( 'gotoDate', date ); }else{ if(allDay) { var timeStamp = $.fullCalendar.formatDate( date, 'dddd+dd+MMMM_u'); var $eventDialog = $('<div/>').load("json-events.php?<?php echo $events_list; ?>&new=1&all_day=1&timestamp=" + timeStamp, null, EventLoad).dialog({autoOpen:false,draggable: false, width: 675, modal:true, position:['center',202], resizable: false, title:'Add an Event'}); $eventDialog.dialog('open').attr('id','eventDialog'); } else { var timeStamp = $.fullCalendar.formatDate( date, 'dddd+dd+MMMM_u'); var $eventDialog = $('<div/>').load("json-events.php?<?php echo $events_list; ?>&new=1&all_day=0&timestamp=" + timeStamp, null, EventLoad).dialog({autoOpen:false,draggable: false, width: 675, modal:true, position:['center',202], resizable: false, title:'Add an Event'}); $eventDialog.dialog('open').attr('id','eventDialog');; } } } }); }); The script json-events.php contains the form and also the code to process the data from the submitted form. What happens when I test the whole thing: - first user click on a day, then time of day. Popup opens with time and date indicated on the form. When user submits the form, dialog closes and calendar refreshes its events.... and the event added by the user appears several times (from 4 to up to 11 times!). The form has been processed several times by the receiving php script?! - second user click, the popup opens, user submit empty form. Form is submitted (validate function not triggered) and user redirected to empty page json-events.php (ajaxForm not triggered either) Obviously, my code is wrong (and dirty as well, sorry). Why is the submitted form, submitted several time to receiving script and why is the javascript function EventLoad triggered only once ? Thank you very much for you help. This problem is killing me !

  • Problem with JS Selectbox Function

    - by Thomas
    I have a selectbox with three options. When a user selects one of the three options, I want a specific div to appear below it. I am trying to write the code that dictates which specific box is to appear when each of the three options is selected. So far, I have only worked on the code that pertains to the first option. However, whenever the user selects any of the three options from the selectbox, the function for the first option is triggered and the div is displayed. My question is two part: 1) How do I write a conditional function that specifically targets the selected option 2) What is the best way to accomplish what I have described above; How do I efficiently go about defining three different functions for three different options in a select box? Here is the function I was working on for the first option: $(document).ready(function(){ var subTableDiv = $("div.subTableDiv"); var subTableDiv1 = $("div.subTableDiv1"); var subTableDiv2 = $("div.subTableDiv2"); subTableDiv.hide(); subTableDiv1.hide(); subTableDiv2.hide(); var selectmenu=document.getElementById("customfields-s-18-s"); selectmenu.onchange=function(){ //run some code when "onchange" event fires var chosenoption=this.options[this.selectedIndex].value //this refers to "selectmenu" if (chosenoption.value ="Co-Op"){ subTableDiv1.slideDown("medium"); } } }); Html: <tr> <div> <select name="customfields-s-18-s" class="dropdown" id="customfields-s-18-s" > <option value="Condominium"> Condominium</option> <option value="Co-Op"> Co-Op</option> <option value="Condop"> Condop</option> </select> </div> </tr> <tr class="subTable"> <td colspan="2"> <div style="background-color: #EEEEEE; border: 1px solid #CCCCCC; padding: 10px;" id="Condominium" class="subTableDiv">Hi There! This is the first Box</div> </td> </tr> <tr class="subTable"> <td colspan="2"> <div style="background-color: #EEEEEE; border: 1px solid #CCCCCC; padding: 10px;" id="Co-Op" class="subTableDiv1">Hi There! This is the Second Box</div> </td> </tr> <tr class="subTable"> <td colspan="2"> <div style="background-color: #EEEEEE; border: 1px solid #CCCCCC; padding: 10px;" id="Condop" class="subTableDiv2">Hi There! This is the Third Box.</div> </td> </tr>

  • IE8 Crashes Strangely on JavaScript Popup

    - by dkris
    Hi, I am facing a strange issue after the popup is created onclick. The popup opens up but hangs immediately on IE8 (works fine on all the other browsers including IE6). But on adding the alertbox as show in the JavaScript code, the popup works fine. I am using **https** and not **http** and i feel popup is not able to load the JS file because of SSL. Here is the how i am generating the onclick event: <a id="forgotPasswordLink" href="#" onclick="openSupportPage();"> Some Text </a> The onclick function is defined this way: function openSupportPage() { var features = "width=700,height=400,status=yes,toolbar=no,menubar=no,location=no,scrollbars=yes"; var winId = window.open('', '', features); winId.focus(); winId.document.open(); winId.document.write('<html><head><title>' + document.title + '</title><link rel="stylesheet" href="./css/default.css" type="text/css">\n'); var is_ie6 = ( window.external && typeof window.XMLHttpRequest == "undefined"); alert(is_ie6);/*The JS include below*/ /*works in popup only with this alert box.*/ /*else IE8 Hangs*/ winId.document.write('<script src="../js/tiny_mce/tiny_mce.js" type="text/javascript">Script_IE8</script>\n'); winId.document.write('<script type="text/javascript">\n'); winId.document.write('function inittextarea() {\n'); winId.document.write('tinyMCE.init({ \n'); winId.document.write('elements : "content",\n'); winId.document.write('theme : "advanced",\n'); winId.document.write('readonly : true,\n'); winId.document.write('mode : "exact",\n'); winId.document.write('theme : "advanced",\n'); winId.document.write('readonly : true,\n'); winId.document.write('setup : function(ed) {\n'); winId.document.write('ed.onInit.add(function() {\n'); winId.document.write('tinyMCE.activeEditor.execCommand("mceToggleVisualAid");\n'); winId.document.write('});\n'); winId.document.write('}\n'); winId.document.write('});}</script>\n'); winId.document.write('</head><body onload="inittextarea()">\n'); winId.document.write(' \n'); var hiddenFrameHTML = document.getElementById("HiddenFrame").innerHTML; hiddenFrameHTML = hiddenFrameHTML.replace(/&amp;/gi, "&"); hiddenFrameHTML = hiddenFrameHTML.replace(/&lt;/gi, "<"); hiddenFrameHTML = hiddenFrameHTML.replace(/&gt;/gi, ">"); winId.document.write(hiddenFrameHTML); winId.document.write('<textarea id="content" rows="10" style="width:100%">\n'); winId.document.write(document.getElementById(top.document.forms[0].id + ":supportStuff").innerHTML); winId.document.write('</textArea>\n'); var hiddenFrameHTML2 = document.getElementById("HiddenFrame2").innerHTML; hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&amp;/gi, "&"); hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&lt;/gi, "<"); hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&gt;/gi, ">"); winId.document.write(hiddenFrameHTML2); winId.document.write('</body></html>\n'); winId.document.close(); } Please help me on this one.

  • Delphi - Why is my global variable "inacessible" when i debug

    - by Antoine Lpy
    I'm building an application that contains around 30 Forms. I need to manage sessions, so I would like to have a global LoggedInUser variable accessible from all forms. I read "David Heffernan"'s post about global variables, and how to avoid them but I thought it would be easier to have a global User variable rather than 30 forms having their own User variable. So i have a unit : GlobalVars unit GlobalVars; interface uses User; // I defined my TUser class in a unit called User var LoggedInUser: TUser; implementation initialization LoggedInUser:= TUser.Create; finalization LoggedInUser.Free; end. Then in my LoginForm's LoginBtnClick procedure I do : unit FormLogin; interface uses [...],User; type TForm1 = class(TForm) [...] procedure LoginBtnClick(Sender: TObject); private { Déclarations privées } public end; var Form1: TForm1; AureliusConnection : IDBConnection; implementation {$R *.fmx} uses [...]GlobalVars; procedure TForm1.LoginBtnClick(Sender: TObject); var Manager : TObjectManager; MyCriteria: TCriteria<TUser>; u : TUser; begin Manager := TObjectManageR.Create(AureliusConnection); MyCriteria :=Manager.Find<TUtilisateur> .Add(TExpression.Eq('login',LoginEdit.Text)) .Add(TExpression.Eq('password',PasswordEdit.Text)); u := MyCriteria.UniqueResult; if u = nil then MessageDlg('Login ou mot de passe incorrect',TMsgDlgType.mtError,[TMsgDlgBtn.mbOK],0) else begin LoggedInUser:=u; //Here I assign my local User data to my global User variable Form1.Destroy; A00Form.visible:=true; end; Manager.Free; end; Then in another form I would like to access this LoggedInUser object in the Menu1BtnClick procedure : Unit C01_Deviations; interface uses System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, FMX.Types, FMX.Graphics, FMX.Controls, FMX.Forms, FMX.Dialogs, FMX.StdCtrls, FMX.ListView.Types, FMX.ListView, FMX.Objects, FMX.Layouts, FMX.Edit, FMX.Ani; type TC01Form = class(TForm) [...] Menu1Btn: TButton; [...] procedure Menu1BtnClick(Sender: TObject); private { Déclarations privées } public { Déclarations publiques } end; var C01Form: TC01Form; implementation uses [...]User,GlobalVars; {$R *.fmx} procedure TC01Form.Menu1BtnClick(Sender: TObject); var Assoc : TUtilisateur_FonctionManagement; ValidationOK : Boolean; util : TUser; begin ValidationOK := False; util := GlobalVars.LoggedInUser; // Here i created a local user variable for debug purposes as I thought it would permit me to see the user data. But i get "Inaccessible Value" as its value util.Nom:='test'; for Assoc in util.FonctionManagement do // Here is were my initial " access violation" error occurs begin if Assoc.FonctionManagement.Libelle = 'Reponsable équipe HACCP' then begin ValidationOK := True; break; end; end; [...] end; When I debug I see "Inaccessible Value" in the value column of my user. Do you have any idea why ? I tried to put an integer in this GlobalVar unit, and i was able to set its value from my login form and read it from my other form.. I guess I could store the user's id, which is an integer, and then retrieve the user from the database using its id. But it seems really unefficient.

  • Backbone.js Model change events in nested collections not firing as expected

    - by Pallavi Kaushik
    I'm trying to use backbone.js in my first "real" application and I need some help debugging why certain model change events are not firing as I would expect. I have a web service at /employees/{username}/tasks which returns a JSON array of task objects, with each task object nesting a JSON array of subtask objects. For example, [{ "id":45002, "name":"Open Dining Room", "subtasks":[ {"id":1,"status":"YELLOW","name":"Clean all tables"}, {"id":2,"status":"RED","name":"Clean main floor"}, {"id":3,"status":"RED","name":"Stock condiments"}, {"id":4,"status":"YELLOW","name":"Check / replenish trays"} ] },{ "id":47003, "name":"Open Registers", "subtasks":[ {"id":1,"status":"YELLOW","name":"Turn on all terminals"}, {"id":2,"status":"YELLOW","name":"Balance out cash trays"}, {"id":3,"status":"YELLOW","name":"Check in promo codes"}, {"id":4,"status":"YELLOW","name":"Check register promo placards"} ] }] Another web service allows me to change the status of a specific subtask in a specific task, and looks like this: /tasks/45002/subtasks/1/status/red [aside - I intend to change this to a HTTP Post-based service, but the current implementation is easier for debugging] I have the following classes in my JS app: Subtask Model and Subtask Collection var Subtask = Backbone.Model.extend({}); var SubtaskCollection = Backbone.Collection.extend({ model: Subtask }); Task Model with a nested instance of a Subtask Collection var Task = Backbone.Model.extend({ initialize: function() { // each Task has a reference to a collection of Subtasks this.subtasks = new SubtaskCollection(this.get("subtasks")); // status of each Task is based on the status of its Subtasks this.update_status(); }, ... }); var TaskCollection = Backbone.Collection.extend({ model: Task }); Task View to renders the item and listen for change events to the model var TaskView = Backbone.View.extend({ tagName: "li", template: $("#TaskTemplate").template(), initialize: function() { _.bindAll(this, "on_change", "render"); this.model.bind("change", this.on_change); }, ... on_change: function(e) { alert("task model changed!"); } }); When the app launches, I instantiate a TaskCollection (using the data from the first web service listed above), bind a listener for change events to the TaskCollection, and set up a recurring setTimeout to fetch() the TaskCollection instance. ... TASKS = new TaskCollection(); TASKS.url = ".../employees/" + username + "/tasks" TASKS.fetch({ success: function() { APP.renderViews(); } }); TASKS.bind("change", function() { alert("collection changed!"); APP.renderViews(); }); // Poll every 5 seconds to keep the models up-to-date. setInterval(function() { TASKS.fetch(); }, 5000); ... Everything renders as expected the first time. But at this point, I would expect either (or both) a Collection change event or a Model change event to get fired if I change a subtask's status using my second web service, but this does not happen. Funnily, I did get change events to fire if I added one additional level of nesting, with the web service returning a single object that has the Tasks Collection embedded, for example: "employee":"pkaushik", "tasks":[{"id":45002,"subtasks":[{"id":1..... But this seems klugey... and I'm afraid I haven't architected my app right. I'll include more code if it helps, but this question is already rather verbose. Thoughts?

  • Is it bad practice to apply class-based design to JavaScript programs?

    - by helixed
    JavaScript is a prototyped-based language, and yet it has the ability to mimic some of the features of class-based object-oriented languages. For example, JavaScript does not have a concept of public and private members, but through the magic of closures, it's still possible to provide the same functionality. Similarly, method overloading, interfaces, namespaces and abstract classes can all be added in one way or another. Lately, as I've been programming in JavaScript, I've felt like I'm trying to turn it into a class-based language instead of using it in the way it's meant to be used. It seems like I'm trying to force the language to conform to what I'm used to. The following is some JavaScript code I've written recently. It's purpose is to abstract away some of the effort involved in drawing to the HTML5 canvas element. /* Defines the Drawing namespace. */ var Drawing = {}; /* Abstract base which represents an element to be drawn on the screen. @param The graphical context in which this Node is drawn. @param position The position of the center of this Node. */ Drawing.Node = function(context, position) { return { /* The method which performs the actual drawing code for this Node. This method must be overridden in any subclasses of Node. */ draw: function() { throw Exception.MethodNotOverridden; }, /* Returns the graphical context for this Node. @return The graphical context for this Node. */ getContext: function() { return context; }, /* Returns the position of this Node. @return The position of this Node. */ getPosition: function() { return position; }, /* Sets the position of this Node. @param thePosition The position of this Node. */ setPosition: function(thePosition) { position = thePosition; } }; } /* Define the shape namespace. */ var Shape = {}; /* A circle shape implementation of Drawing.Node. @param context The graphical context in which this Circle is drawn. @param position The center of this Circle. @param radius The radius of this circle. @praram color The color of this circle. */ Shape.Circle = function(context, position, radius, color) { //check the parameters if (radius < 0) throw Exception.InvalidArgument; var node = Drawing.Node(context, position); //overload the node drawing method node.draw = function() { var context = this.getContext(); var position = this.getPosition(); context.fillStyle = color; context.beginPath(); context.arc(position.x, position.y, radius, 0, Math.PI*2, true); context.closePath(); context.fill(); } /* Returns the radius of this Circle. @return The radius of this Circle. */ node.getRadius = function() { return radius; }; /* Sets the radius of this Circle. @param theRadius The new radius of this circle. */ node.setRadius = function(theRadius) { radius = theRadius; }; /* Returns the color of this Circle. @return The color of this Circle. */ node.getColor = function() { return color; }; /* Sets the color of this Circle. @param theColor The new color of this Circle. */ node.setColor = function(theColor) { color = theColor; }; //return the node return node; }; The code works exactly like it should for a user of Shape.Circle, but it feels like it's held together with Duct Tape. Can somebody provide some insight on this?

  • Background changes by itself and procedure repeats many times until I release the mouse button

    - by Robert
    Dear community, I am a student, and I'm working on a little slots game (if the same random number comes up 3 timed, you win). I use Borland Pascal 7. I use graph to make this a bit more visual, but when I start the game my background turns from black to grey, and the other problem is that if I click the game start button, the game runs many times until I release the mouse button.

  • wave.getState() returns null

    - by RMorrisey
    When trying to call wave.getState() in my Google Wave gadget, I get back null (no state object). How can I initialize the Wave state object? I am working in the Wave Sandbox. My ModulePrefs contains the following: <Require feature="wave" /> <Require feature="rpc"/> I got the "rpc" feature from some google groups post when searching for a fix, but it doesn't seem to be any help. The gadget contains a jQuery plugin, which defines the classes I use (not shown), attaches an event handler to the link that shows up in edit mode, and sets up the callback methods with the google wave gadget initializer: $.fn.extend({ $.gork.InitPass.newButtonClick = function newButtonClick() { var jer = new $.gork.InitPass.Player('Jeremias', 12, 2); var delta = {}; delta[jer.name] = jer.serialize(); wave.getState().submitDelta(delta); }; $.gork.InitPass.modeCallback = function modeCallback() { var state = wave.getState(); var mode = wave.getMode(); $.gork.InitPass.getContainer().ipCombatState(state, (mode == wave.Mode.EDIT)); }; $.gork.InitPass.stateCallback = function stateCallback() { $.gork.InitPass.getContainer().ipCombatState( wave.getState(), (wave.getMode() == wave.Mode.EDIT)); alert('state'); }; $.gork.InitPass.init = function init() { if (wave && wave.isInWaveContainer()) { var mode = wave.getMode(); $('.gork-ip-container').ipCombatState(null, (mode == wave.Mode.EDIT)); wave.setModeCallback($.gork.InitPass.modeCallback); wave.setStateCallback($.gork.InitPass.stateCallback); } }; })(jQuery); gadgets.util.registerOnLoadHandler($.gork.InitPass.init); $(function ready() { $.gork.InitPass.getContainer().find('.gork-ip-edit .addSection a.newButton').click( $.gork.InitPass.newButtonClick); }); So there are two main pieces of functionality here: When the mode changes, ipCombatState(...) is called. This changes the visual appearance of the gadget when the user puts the gadget in Edit mode (CTRL+E), by hiding the view DIV and displaying the edit DIV. The newButtonClick callback (which is attached to the link "a.newButton" in the edit container) is supposed to add Jeremias (Nate's Shadowrun character) to the gadget state, so that he'll be appear as a table row in edit mode. I have verified that the initializer method is called, and the view/edit mode switch works just fine (except the state is null). When I click on the new button link (the link at the bottom in edit mode), and trigger the newButtonClick handler, I get an error because wave.getState() also returns null. How can I initialize the wave state so that I can work with it? The purpose of my gadget will be to keep track of combat initiative order in a Shadowrun tabletop game (4th Ed). You can test it out in Wave and see what I have so far: http://gorkwobble.herobo.com/wave/init-pass.xml The actual javascript code is externalized to: http://gorkwobble.herobo.com/wave/init-pass.js P.S. If any Shadowrun players read this, and want to hear about it when I get the gadget working, leave a comment and I'll wave you.

  • Recursive XSD Help

    - by Alon
    Hi, i'm trying to learn a little bit XSD and I'm trying to create a XSD for this xml: <Document> <TextBox Name="Username" /> <TextBox Name="Password" /> </Document> ... so there's an element, which is an abstract complex type. Every element have elements and so on. Document and TextBox are extending Element. I trid this: <?xml version="1.0" encoding="utf-8" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="Document"> <xs:complexType> <xs:complexContent> <xs:extension base="Element"> </xs:extension> </xs:complexContent> </xs:complexType> </xs:element> <xs:complexType name="Element" abstract="true"> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Element" type="Element"></xs:element> </xs:sequence> </xs:complexType> <xs:complexType name="TextBox"> <xs:complexContent> <xs:extension base="Element"> <xs:attribute name="Name" type="xs:string" /> </xs:extension> </xs:complexContent> </xs:complexType> </xs:schema> I compiled it to C# with Xsd2Code, and now I try to deserialize it: var serializer = new XmlSerializer(typeof(Document)); var document = (Document)serializer.Deserialize(new FileStream("Document1.xml", FileMode.Open)); foreach (var element in document.Element1) { Console.WriteLine(((TextBox)element).Name); } Console.ReadLine(); and it dosen't print anything. When I try to serialize it like so: var serializer = new XmlSerializer(typeof(Document)); var document = new Document(); document.Element1 = new List<Element>(); document.Element1.Add(new TextBox() { Name = "abc" }); serializer.Serialize(new FileStream("d.xml", FileMode.Create), document); ...the output is: <?xml version="1.0"?> <Document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Element1> <Element xsi:type="TextBox"> <Element1 /> <Name>abc</Name> </Element> </Element1> </Document> When it should be: <Document> <TextBox Name="abc" /> </Document> Any ideas how to fix the xsd or another code generator? Thanks.

  • Cakephp - Banner Problem

    - by Joe Elliott
    Hi guys I have a banner rotator on my main page and it was working but it has stopped. All I have done before it stopped was modified some of the db fields. I added to fields position and company and deleted the field 'description.' It was a friend of a friend that made this part of the site for me while i was on holiday so i dont know which files i should show you cos dont know exactly what hes done but im guessing the following ones are the ones you need. banner_view <div id="banner"> <?php if(!empty($banners) && ($banners['Banner']['position']=='Top')){ foreach($banners as $banner){ ?> <a href="<?php echo $banner['Banner']['url']; ?>"><img src="<?php echo $banner['Banner']['path']; ?>" alt="<?php echo $banner['Banner']['company']; ?>" /></a> <?php } } ?> </div> banner_controller <?php class BannersController extends AppController { var $name = 'Banners'; var $helpers = array('Html', 'Form', 'Ajax','Javascript'); var $layout = 'ajax'; var $components = array('Session', 'Cookie'); function beforeFilter() { parent::beforeFilter(); $this->Auth->allow('index','featrot'); if(strpos($this->here, 'admin')) { $this->layout = 'admin'; } } function index() { Configure::write('debug',0); $this->Banner->recursive = 0; $this->paginate['Banner']; $banners = $this->paginate(); if($banners) { $this->set('banners', $banners); } } function featrot() { Configure::write('debug',0); $this->Banner->recursive = 0; $this->paginate['Banner']; $banners = $this->paginate(); if($banners) { $this->set('banners', $banners); } } function admin_edit(){ $this->pageTitle='Admin section - .: Banners Edit:.'; $banners = $this->Banner->find('first'); $id = $banners['Banner']['id']; if (!empty($this->data)) { $this->Banner->id = $id; if ($this->Banner->save($this->data)) { $this->Session->setFlash(__('The Banner has been updated', true)); } else { $this->Session->setFlash(__('The Banner could not update. Please, try again.', true)); } } if (empty($this->data)) { $this->data = $this->Banner->read(null, $id); } } function admin_display_banners($id=null){ $this->pageTitle='Admin section - .: Banners Setting :.'; if (!empty($this->data)) { $this->Banner->id = $id; if ($this->Banner->save($this->data)) { $this->Session->setFlash(__("Banner#$id has been updated", true)); $this->Banner->id = null; } else { $this->Session->setFlash(__("Banner#$id could not update. Please, try again.", true)); } } $this->data = null; $this->Banner->recursive = -1; $this->paginate['Banner']; $banners = $this->paginate('Banner'); $this->set('banners', $banners); } } ?> banner_model <?php class Banner extends AppModel { var $name = 'Banner'; } ?> Hope this is all the details you need. Thanks in advance folks :) Joe :)

  • How to deploy a visual studio custom tool?

    - by Aen Sidhe
    Hello. I have a my own custom tool for Visual Studio 2008 SP1. It consists of 5 assemblies: 3 assemblies with code that used heavily in my other projects, 1 assembly-wrapper above VS2008 SDK and assembly with the tool. If I'd debug my tool from visual studio, using "Run external program" option with command line "C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" and arguments "/ranu /rootsuffix Exp" all work perfectly. After that I trying to deploy it to my working VS copy, not to experimental hive doing: gacutil /i Asm1.dll for all my assemblies and doing RegAsm Asm1.dll only for assembly with custom tool. Neither of utils prints any error, all work as planned, even registry keys appeared. But my tool don't work even after PC restart. What did I do wrong? Wrapper looks like that: [ComVisible(true)] public abstract class CustomToolBase : IVsSingleFileGenerator, IObjectWithSite { #region IVsSingleFileGenerator Members int IVsSingleFileGenerator.DefaultExtension(out string pbstrDefaultExtension) { pbstrDefaultExtension = ".cs"; return 0; } int IVsSingleFileGenerator.Generate(string wszInputFilePath, string bstrInputFileContents, string wszDefaultNamespace, IntPtr[] rgbOutputFileContents, out uint pcbOutput, IVsGeneratorProgress pGenerateProgress) { GenerationEventArgs gea = new GenerationEventArgs( bstrInputFileContents, wszInputFilePath, wszDefaultNamespace, new ServiceProvider(Site as Microsoft.VisualStudio.OLE.Interop.IServiceProvider) .GetService(typeof(ProjectItem)) as ProjectItem, new GenerationProgressFacade(pGenerateProgress) ); if (OnGenerateCode != null) { OnGenerateCode(this, gea); } byte[] bytes = gea.GetOutputCodeBytes(); int outputLength = bytes.Length; rgbOutputFileContents[0] = Marshal.AllocCoTaskMem(outputLength); Marshal.Copy(bytes, 0, rgbOutputFileContents[0], outputLength); pcbOutput = (uint)outputLength; return VSConstants.S_OK; } #endregion #region IObjectWithSite Members void IObjectWithSite.GetSite(ref Guid riid, out IntPtr ppvSite) { IntPtr pUnk = Marshal.GetIUnknownForObject(Site); IntPtr intPointer = IntPtr.Zero; Marshal.QueryInterface(pUnk, ref riid, out intPointer); ppvSite = intPointer; } void IObjectWithSite.SetSite(object pUnkSite) { Site = pUnkSite; } #endregion #region Public Members public object Site { get; private set; } public event EventHandler<GenerationEventArgs> OnGenerateCode; [ComRegisterFunction] public static void Register(Type type) { using (var parent = Registry.LocalMachine.OpenSubKey(@"Software\Microsoft\VisualStudio\9.0", true)) foreach (CustomToolRegistrationAttribute ourData in type.GetCustomAttributes(typeof(CustomToolRegistrationAttribute), false)) ourData.Register(x => parent.CreateSubKey(x), (x, name, value) => x.SetValue(name, value)); } [ComUnregisterFunction] public static void Unregister(Type type) { using (var parent = Registry.LocalMachine.OpenSubKey(@"Software\Microsoft\VisualStudio\9.0", true)) foreach (CustomToolRegistrationAttribute ourData in type.GetCustomAttributes(typeof(CustomToolRegistrationAttribute), false)) ourData.Unregister(x => parent.DeleteSubKey(x, false)); } #endregion } My tool code: [ComVisible(true)] [Guid("55A6C192-D29F-4e22-84DA-DBAF314ED5C3")] [CustomToolRegistration(ToolName, typeof(TransportGeneratorTool))] [ProvideObject(typeof(TransportGeneratorTool))] public class TransportGeneratorTool : CustomToolBase { private const string ToolName = "TransportGeneratorTool"; public TransportGeneratorTool() { OnGenerateCode += GenerateCode; } private static void GenerateCode(object s, GenerationEventArgs e) { try { var serializer = new XmlSerializer(typeof (Parser.System)); using (var reader = new StringReader(e.InputText)) using (var writer = new StringWriter(e.OutputCode)) { Generator.System = (Parser.System) serializer.Deserialize(reader); Generator.System.Namespace = e.Namespace; Generator.GenerateSource(writer); } } catch (Exception ex) { e.Progress.GenerateError(ex.ToString()); } } } Resulting registry keys: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Generators] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Generators\{FAE04EC1-301F-11D3-BF4B-00C04F79EFBC}] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Generators\{FAE04EC1-301F-11D3-BF4B-00C04F79EFBC}\TransportGeneratorTool] @="TransportGeneratorTool" "CLSID"="{55a6c192-d29f-4e22-84da-dbaf314ed5c3}" "GeneratesDesignTimeSource"=dword:00000001 "GeneratesSharedDesignTimeSource"=dword:00000001
