  • jquery-ui autocomplete with ASP MVC suggestions not displaying

    - by adamnickerson
    I have been trying to get a simple example of the jquery-ui autocomplete to work. I have a controller setup to handle the query, and it returns the json that looks to be in order, but I am getting no suggestions showing up. Here are the js libraries I am including: <script type="text/javascript" language="javascript" src="/Scripts/jquery-1.4.1.js"></script> <script type="text/javascript" language="javascript" src="/Scripts/jquery-ui-1.8.1.custom.min.js"></script> <link href="/Content/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> and here is the javascript and the form tags: <script type="text/javascript"> $(function () { $("#organization").autocomplete({ source: function (request, response) { $.ajax({ url: '/Organization/OrganizationLookup', dataType: "json", data: { limit: 12, q: request.term } }) }, minLength: 2 }); }); </script> <div class="ui-widget"> <label for="organization">Organization: </label> <input id="organization" /> </div> I get back a json response that looks reasonable from my controller: [{"id":"Sector A","value":"Sector A"},{"id":"Sector B","value":"Sector B"},{"id":"Sector C","value":"Sector C"}] id and value seem to be the default naming that autocomplete is looking for. But I get no joy at all. Any thoughts?

  • Array of templated structs

    - by Jakub Mertlik
    I have structs templated by int derived from a Base struct. struct Base { int i; double d; }; template< int N > struct Derv : base { static const int mN = N; }; I need to make an array of Derv< N where N can vary for each struct in that array. I know C/C++ does not allow arrays of objects of different types, but is there a way around this? I was thinking of separating the type information somehow (hints like pointers to Base struct or usage of union spring to my mind, but with all of these I don't know how to store the type information of each array element for usage DURING COMPILE TIME). As you can see, the memory pattern of each Derv< N is the same. I need to access the type of each array element for template specialization later in my code. The general aim of this all is to have a compile-time dispatch mechanism without the need to do a runtime "type switch" somewhere in the code. Thank you.

  • Passing Derived Class Instances as void* to Generic Callbacks in C++

    - by Matthew Iselin
    This is a bit of an involved problem, so I'll do the best I can to explain what's going on. If I miss something, please tell me so I can clarify. We have a callback system where on one side a module or application provides a "Service" and clients can perform actions with this Service (A very rudimentary IPC, basically). For future reference let's say we have some definitions like so: typedef int (*callback)(void*); // This is NOT in our code, but makes explaining easier. installCallback(string serviceName, callback cb); // Really handled by a proper management system sendMessage(string serviceName, void* arg); // arg = value to pass to callback This works fine for basic types such as structs or builtins. We have an MI structure a bit like this: Device <- Disk <- MyDiskProvider class Disk : public virtual Device class MyDiskProvider : public Disk The provider may be anything from a hardware driver to a bit of glue that handles disk images. The point is that classes inherit Disk. We have a "service" which is to be notified of all new Disks in the system, and this is where things unravel: void diskHandler(void *p) { Disk *pDisk = reinterpret_cast<Disk*>(p); // Uh oh! // Remainder is not important } SomeDiskProvider::initialise() { // Probe hardware, whatever... // Tell the disk system we're here! sendMessage("disk-handler", reinterpret_cast<void*>(this)); // Uh oh! } The problem is, SomeDiskProvider inherits Disk, but the callback handler can't receive that type (as the callback function pointer must be generic). Could RTTI and templates help here? Any suggestions would be greatly appreciated.

  • Binding a ListBox's SelectedItem in the presence of BindingNavigator

    - by Reinderien
    Hello. I'm trying to bind a ListBox's SelectedItem data to a property. The following code is an example: using System; using System.Collections.Generic; using System.Windows.Forms; namespace BindingFailure { static class Program { class OuterObject { public string selected { get; set; } public List<string> strings { get; set; } } public static void Main() { List<OuterObject> objs = new List<OuterObject>() { new OuterObject(), new OuterObject() }; objs[0].strings = new List<string> { "one", "two", "three" }; objs[1].strings = new List<string> { "four", "five", "six" }; Form form = new Form(); BindingSource obs = new BindingSource(objs, null), ibs = new BindingSource(obs, "strings"); BindingNavigator nav = new BindingNavigator(obs); ListBox lbox = new ListBox(); lbox.DataSource = ibs; lbox.DataBindings.Add(new Binding("SelectedItem", obs, "selected")); form.Controls.Add(nav); form.Controls.Add(lbox); lbox.Location = new System.Drawing.Point(30, 30); Application.Run(form); } } } If you just select an item, move forward, select an item and then exit, it works as expected. But if you switch back and forth between the two outer objects with the navigator, the selected item seems to be overwritten with an incorrect value. Ideas on how to fix this? Thanks in advance.

  • How can I bind a simple Javascript array to an MVC3 controller action method?

    - by Sergio Tapia
    Here is the javascript code I use to create the array and send it on it's way: <script type="text/javascript" language="javascript"> $(document).ready(function () { $("#update-cart-btn").click(function() { var items = []; $(".item").each(function () { var productKey = $(this).find("input[name='item.ProductId']").val(); var productQuantity = $(this).find("input[type='text']").val(); items[productKey] = productQuantity; }); $.ajax({ type: "POST", url: "@Url.Action("UpdateCart", "Cart")", data: items, success: function () { alert("Successfully updated your cart!"); } }); }); }); </script> The items object is properly constructed with the values I need. What data type must my object be on the backend of my controller? I tried this but the variable remains null and is not bound. [Authorize] [HttpPost] public ActionResult UpdateCart(object[] items) // items remains null. { // Some magic here. return RedirectToAction("Index"); }

  • Event problems with FF

    - by s4v10r
    Hi all :) Made this sweet little script to auto change fields after input. Works nicely in IE, Chrome and Safari, but not in FF or opera. JS code: function fieldChange(id, e){ var keyID = (window.event) ? event.keyCode : e.keyCode; if (document.getElementById(id).value.length >= 2){ if (keyID >= 48 && keyID <= 57 || keyID >= 96 && keyID <= 105){ switch(id){ case "textf1": document.getElementById("textf2").focus(); break; case "textf2": document.getElementById("textf3").focus(); break; case "textf3": if (document.getElementById(id).value.length >= 4){ document.getElementById("nubPcode").focus(); } break; } } } HTML: <div class="privateOrderSchema"> <input type="text" id="textf1" name="textf1" maxlength="2" size="4" onKeyUp="fieldChange('textf1')"/>- <input type="text" id="textf2" name="textf2" maxlength="2" size="4" onKeyUp="fieldChange('textf2')" />- <input type="text" id="textf3" name="textf3" maxlength="4" size="5" onKeyUp="fieldChange('textf3')" /> </div> <div class="privateOrderSchema"> <input type="text" id="nubPcode" name="nubPcode" size="4" maxlength="4" /> <br /> </div> Does anybody know how to send the "e" var in this scenario? Tnx all :D ur gr8!

  • Java equivalent of the VB Request.InputStream

    - by Android Addict
    I have a web service that I am re-writing from VB to a Java servlet. In the web service, I want to extract the body entity set on the client-side as such: StringEntity stringEntity = new StringEntity(xml, HTTP.UTF_8); stringEntity.setContentType("application/xml"); httppost.setEntity(stringEntity); In the VB web service, I get this data by using: Dim objReader As System.IO.StreamReader objReader = New System.IO.StreamReader(Request.InputStream) Dim strXML As String = objReader.ReadToEnd and this works great. But I am looking for the equivalent in Java. I have tried this: ServletInputStream dataStream = req.getInputStream(); byte[] data = new byte[dataStream.toString().length()]; dataStream.read(data); but all it gets me is an unintelligible string: data = [B@68514fec Please advise. Edit Per the answers, I have tried: ServletInputStream dataStream = req.getInputStream(); ByteArrayOutputStream buffer = new ByteArrayOutputStream(); int r; byte[] data = new byte[1024*1024]; while ((r = dataStream.read(data, 0, data.length)) != -1) { buffer.write(data, 0, r); } buffer.flush(); byte[] data2 = buffer.toByteArray(); System.out.println("DATA = "+Arrays.toString(data2)); whichs yields: DATA = [] and when I try: System.out.println("DATA = "+data2.toString()); I get: DATA = [B@15282c7f So what am I doing wrong? As stated earlier, the same call to my VB service gives me the xml that I pass in.

  • Visual Studio IntelliSense - IHideObjectMembers trick doesn't work. What am I missing?

    - by stakx
    The IHideObjectMembers trick can be used e.g. in fluent interface implementations to hide System.Object members from IntelliSense. (If you don't know this trick, you can read up on it via the above link; I'm just repeating the interface's usual declaration here:) using System; using System.ComponentModel; [EditorBrowsable(EditorBrowsableState.Never)] public interface IHideObjectMembers { [EditorBrowsable(EditorBrowsableState.Never)] Type GetType(); [EditorBrowsable(EditorBrowsableState.Never)] int GetHashCode(); [EditorBrowsable(EditorBrowsableState.Never)] string ToString(); [EditorBrowsable(EditorBrowsableState.Never)] bool Equals(object obj); } I'm now supposed to be able to hide System.Object members on another type as follows: public class SomeClass : IHideObjectMembers { ... } or: public class ISomeInterface : IHideObjectMembers { ... } I tried this in both VS 2008 Express and VS 2008 Standard. However, no members are hidden from IntelliSense at all. I have used the EditorBrowsableAttribute in different projects and it always worked well; however, it doesn't work in this particular scenario. If things had worked as expected, I would only have seen the SomeMethodTwo method. Am I missing something?

  • How to retrieve the Description property from SettingsProperty?

    - by BadNinja
    For each item in my application's settings, I've added text to its Description Property which I want to retrieve at runtime. I'm sure I'm missing some basic logical nuance here, but everything I've tried has failed. Clearly, my understanding of what value needs to be passed to the Attributes property of the SettingsProperty class is wrong. I'm further confused by the fact that when I iterate through all they keys returned by SettingsProperty.Attributes.Keys, I can see "System.Configuration.SettingsDescriptionAttribute", but when I pass that string in as the key to the Attributes property, null is returned. Any insight into how to properly retrieve the value Description Property would be very much appreciated. Thanks. :) public void MyMethod() { SettingsPropertyCollection MyAppProperties = Properties.Settings.Default.Properties; IEnumerator enumerator = MyAppProperties.GetEnumerator(); // Iterate through all the keys to see what we have.... while (enumerator.MoveNext()) { SettingsProperty property = (SettingsProperty)enumerator.Current; ICollection myKeys = property.Attributes.Keys; foreach (object theKey in myKeys) System.Diagnostics.Debug.Print(theKey.ToString()); // One of the keys returned is: System.Configuration.SettingsDescriptionAttribute } enumerator.Reset(); while (enumerator.MoveNext()) { SettingsProperty property = (SettingsProperty)enumerator.Current; string propertyValue = property.DefaultValue.ToString(); // This fails: Null Reference string propertyDescription = property.Attributes["System.Configuration.SettingsDescriptionAttribute"].ToString(); // Do stuff with strings... } }

  • pass other form elements to ajax suggestion box script

    - by Alex Calder
    I paid somebody to build me a jQuery AJAX suggestion box script a while back. It works great. Now I'm trying to learn about it enough to modify it to do something different. Right now, the script that generates the suggestions just takes the query text and does the same check every time. Now, I want to be able to pass along additional info so different things are looked for with each instance of a search box. The HTML... simple, obvious. input class="suggest" name="q" type="text" autocomplete="off" / The jQuery looks like this: jQuery(document).ready(function() { $('.suggest').autocomplete( { source:'output.php', minLength:3, focus: function (event, ui) { $(event.target).val(ui.item.label); return false; } } ); [snip] } Instead of: source:'output.php', minLength:3, I'd like: source:'output.php?arg1=blah1&arg2=blah2', minLength:3, where arg1 and arg2 are passed along in the form... input class="suggest" name="q" type="text" autocomplete="off" / input type="hidden" name="arg1" value="blah1" input type="hidden" name="arg2" value="blah2" Does this make sense? Thanks guys. I know just about "this much" about OOL's and javascript, so I'm learning... Alex

  • SQL Server INSERT ... SELECT Statement won't parse

    - by Jim Barnett
    I am getting the following error message with SQL Server 2005 Msg 120, Level 15, State 1, Procedure usp_AttributeActivitiesForDateRange, Line 18 The select list for the INSERT statement contains fewer items than the insert list. The number of SELECT values must match the number of INSERT columns. I have copy and pasted the select list and insert list into excel and verified there are the same number of items in each list. Both tables an additional primary key field with is not listed in either the insert statement or select list. I am not sure if that is relevant, but suspicious it may be.

  • PEAR mail not sending to .eu email addresses

    - by andy-score
    I have a PEAR mailing script that is used to send newsletters from a clients website. I've used the same code before to produce another newsletter system and it has worked well and been used to send emails to various addresses, however our latest client has email addresses ending .eu and this seems to cause a problem. When the newsletter is sent from the site to the various subscribers, including gmail, hotmail, yahoo and our own company emails, the emails are received correctly by all but the clients email addresses, the ones ending in .eu. As there is nothing different between their mailing system and our own, which is run from the same hosting company, I have to conclude that it is something to do with the domain name. The emails are being sent to the addresses from the system, as I have a log file storing the email addresses when the mail out function is called, but the newsletter never appears in the inbox. I have created a new email account for the domain and that too isn't receiving the emails. It's not going into a spam folder as the webmail system marks spam by adding SPAM into the subject. I've tried to log if there are any errors using the following foreach($subscribers as $recipient) { $send_newsletter = $mail->send($recipient, $headers, $body); // LOG INFO $message = $recipient; if($send_newsletter) { $message .= ' SENT'; } elseif(PEAR::isError($send_newsletter)) { $message .= ' ERROR: '.$send_newsletter->getMessage(); } $message .= ' | '; fwrite($log_file,$message); } However this simple returns SENT for all recipients, so in theory there isn't anything wrong with the mailing function. I don't know a great deal about PEAR or the mailing function so I may be missing something important, but I'd have thought seeing the last thing to happen is sending the email out, and that seems to work, then it should reach the clients inbox. Is this something to do with the PEAR mailing function not liking .eu addresses or is it more likely to be something wrong in my code or with their domain? Any help is greatly appreciated as the client and myself are getting both confused and frustrated by the whole thing. Cheers

  • how to automate the testing of a text based menu

    - by Reagan Penner
    Hi there, I have a text based menu running on a remote Linux host. I am using expect to ssh into this host and would like to figure out how to interact with the menus. Interaction involves arrowing up, down and using the enter and back arrow keys. For example, Disconnect Data Collection > Utilities > Save Changes When you enter the system Disconnect is highlighted. So simply pressing enter twice you can disconnect from the system. Second enter confirms the disconnect. The following code will ssh into my system and bring up the menu. If I remove the expect eof and try to send "\r" thinking that this would select the Disconnect menu option I get the following error: "write() failed to write anything - will sleep(1) and retry..." #!/usr/bin/expect set env(TERM) vt100 set password abc123 set ipaddr 162.116.11.100 set timeout -1 match_max -d 100000 spawn ssh root@$ipaddr exp_internal 1 expect "*password:*" send -- "$password\r" expect "Last login: *\r" expect eof I have looked at the virterm and term_expect examples but cannot figure out how to tweak them to work for me. If someone can point me in the right direction I would greatly appreciate it. What I need to know is can I interact with a text based menu system and what is the correct method for doing this, examples if any exist would be great. thanks, -reagan

  • How am I able to create A List<T> containing a generic Interface?

    - by Conrad Clark
    I have a List which must contain IInteract Objects. But IInteract is a generic interface which requires 2 type arguments. My main idea is iterate through a list of Objects and "Interact" one with another if they didn't interact yet. So i have this object List<IObject> WorldObjects = new List<IObject>(); and this one: private List<IInteract> = new List<IInteract>(); Except I can't compile the last line because IInteract requires 2 type arguments. But I don't know what the arguments are until I add them. I could add interactions between Objects of Type A and A... or Objects of Type B and C. I want to create "Interaction" classes which do something with the "acting" object and the "target" object, but I want them to be independent from the objects... so I could add an Interaction between for instance... "SuperUltraClass" and... an "integer". Am I using the wrong approach?

    Hi, whenever i try to serialize the dictionary i get the exception: System.ArgumentException: Type 'System.Collections.Generic.Dictionary`2[[Foo.DictionarySerializationTest+TestEnum, Foo, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null],[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' is not supported for serialization/deserialization of a dictionary, keys must be strings or object My Testcase is: public class DictionarySerializationTest { private enum TestEnum { A, B, C } public void SerializationTest() { Dictionary<TestEnum, Int32> data = new Dictionary<TestEnum, Int32>(); data.Add(TestEnum.A, 1); data.Add(TestEnum.B, 2); data.Add(TestEnum.C, 3); JavaScriptSerializer serializer = new JavaScriptSerializer(); String result = serializer.Serialize(data); // Throws } public void SerializationStringTest() { Dictionary<String, Int32> data = new Dictionary<String, Int32>(); data.Add(TestEnum.A.ToString(), 1); data.Add(TestEnum.B.ToString(), 2); data.Add(TestEnum.C.ToString(), 3); JavaScriptSerializer serializer = new JavaScriptSerializer(); String result = serializer.Serialize(data); // Succeeds } } Of course i could use .ToString() whenever i enter something into the Dictionary but since it's used quite often in performance relevant methods i would prefer using the enum. My only solution is using .ToString() and converting before entering the performance critical regions but that is clumsy and i would have to change my code structure just to be able to serialize the data. Does anyone have an idea how i could serialize the dictionary as <Enum, Int32>? I use the System.Web.Script.Serialization.JavaScriptSerializer for serialization.

  • Object reference not set to an instance of an object.

    I have the following code - private static void convert() { string csv = File.ReadAllText("test.csv"); string year = "2008"; XDocument doc = ConvertCsvToXML(csv, new[] { "," }); doc.Save("update.xml"); XmlTextReader reader = new XmlTextReader("update.xml"); XmlDocument testDoc = new XmlDocument(); testDoc.Load(@"update.xml"); XDocument turnip = XDocument.Load("update.xml"); webservice.singleSummary[] test = new webservice.singleSummary[1]; webservice.FinanceFeed CallWebService = new webservice.FinanceFeed(); foreach(XElement el in turnip.Descendants("row")) { test[0].account = el.Descendants("var").Where(x => (string)x.Attribute("name") == "account").SingleOrDefault().Attribute("value").Value; test[0].actual = System.Convert.ToInt32(el.Descendants("var").Where(x => (string)x.Attribute("name") == "actual").SingleOrDefault().Attribute("value").Value); test[0].commitment = System.Convert.ToInt32(el.Descendants("var").Where(x => (string)x.Attribute("name") == "commitment").SingleOrDefault().Attribute("value").Value); test[0].costCentre = el.Descendants("var").Where(x => (string)x.Attribute("name") == "costCentre").SingleOrDefault().Attribute("value").Value; test[0].internalCostCentre = el.Descendants("var").Where(x => (string)x.Attribute("name") == "internalCostCentre").SingleOrDefault().Attribute("value").Value; MessageBox.Show(test[0].account, "Account"); MessageBox.Show(System.Convert.ToString(test[0].actual), "Actual"); MessageBox.Show(System.Convert.ToString(test[0].commitment), "Commitment"); MessageBox.Show(test[0].costCentre, "Cost Centre"); MessageBox.Show(test[0].internalCostCentre, "Internal Cost Centre"); CallWebService.updateFeedStatus(test, year); } It is coming up with the error of - NullReferenceException was unhandled, saying that the object reference not set to an instance of an object. The error occurs on the first line test[0].account. How can I get past this?

  • Exception while hosting a WCF Service in a DependencyInjection Module ?

    - by Maciek
    Hello, I've written a small just-for-fun console project using Ninject, I'm pasting some of the code below just so that you get the idea : Program.cs using System; using Ninject; using Ninjectionn.Modules; // My namespace for my modules namespace Ninjections { class Program { static void Main(string[] args) { IKernel kernel = new StandardKernel(); kernel.Load<ServicesHostModule>(); Console.ReadKey(); } } } ServicesHostModule.cs using System; using System.ServiceModel; using Ninject; using Ninject.Modules; namespace Ninjections.Modules { public class ServicesHostModule : INinjectModule { #region INinjectModule Members public string Name { get { return "ServicesHost"; }} public void OnLoad(IKernel kernel) { if(m_host != null) m_host.Close(); else m_host = new ServiceHost(typeof(WCFTestService)); m_host.Open(); // (!) EXCEPTION HERE } public void OnUnLoad(IKernel kernel) { m_host.Close(); } #endregion } } ITestWCFService.cs using System.ServiceModel; namespace Ninjections.Modules { [ServiceContract] public interface ITestWCFService { [OperationContract] string GetString1(); [OperationContract] string GetString2(); } } An auto-generated App.config is in the ServicesHostModule project. I've "added" an existing item (the app config) as link in the main project. Q: at the m_host.Open(); line, an InvalidOperationException occurs. The message says : "Service "Ninjections.Modules.TestWCFService" has zero application endopints. What's wrong?

  • C# - retrieve file path from config file - @ doesn't do it's magic

    - by Bart
    Hi guys, I'm currently working on a web service that retrieves an XML message, archives it and then processes it further. The archive folder is read from the Web.config. This is what the archive method looks like private void Archive(System.Xml.XmlDocument xmlDocument) { try { string directory = System.Configuration.ConfigurationManager.AppSettings.Get("ArchivePath"); ParseMessage(xmlDocument); directory = string.Format(@"{0}\{1}\{2}", @directory, _senderService, DateTime.Now.ToString("MMMyyyy")); System.IO.Directory.CreateDirectory(directory); string Id = _messageID; string senderService = _senderService; xmlDocument.Save(directory + @"\" + DateTime.Now.ToString("yyyyMMdd_") + Id + "_" + System.Guid.NewGuid().ToString().Substring(0, 13) + ".xml"); } The path structure I retrieve is C:\Program Files\Subfolder\Subfolder. In the development, QA, UAT and PRD environments everything works fine. But on another machine I now need to install the web service on (which I cannot debug, unfortunately), the directory string is 'C:Files'. Just to be sure I double checked the .NET version on the different machines (I thought perhaps the usage of @ before a string was version-dependent); all machines use 2.0.50727. Does anyone recognize this problem? Thanks in advance!
