  • How to get Firebug to tell me what error jquery's .load() is returning?

    - by Edward Tanguay
    I'm trying to find out what data/error jquery's .load() method is returning in the following code (the #content element is blank so I assume there is some kind of error). Where do I find in Firebug what content or error .load() is returning? How can I use console.log to find out at least what content is being returned? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.3.2"); google.setOnLoadCallback(function() { $('#loadButton').click(loadDataFromExernalWebsite); }); function loadDataFromExernalWebsite() { console.log("test"); $('#content').load('http://www.tanguay.info/web/getdata/index.php?url=http://www.tanguay.info/knowsite/data.txt', function() { alert('Load was performed.'); }); } </script> </head> <body> <p>Click the button to load content:</p> <p id="content"></p> <input id="loadButton" type="button" value="load content"/> </body> </html>

  • Dojo DataGrid, programmatic creation

    - by djna
    I'm trying to create a DataGrid dynamically. Declarative creation is working fine: A source of data: <span dojoType="dojo.data.ItemFileReadStore" jsId="theStore" url="dataonly001.json"> </span> a simple layout: <script type="text/javascript" > var layout = [ { field: 'custId', name: 'Id', } // more items elided ... ]; </script> The grid: <body class="tundra" id="mainbody"> <div id="grid" dojoType="dojox.grid.DataGrid" store="theStore" structure="layout" autoWidth="true" ></div> </body> And I get the grid displayed nicely. Instead, I want to create the grid dynamically. For the sake of figuring out what's broken I've tried to use exactly the same layout and store, removing just teh grid declaration and adding this script: <script type="text/javascript" djConfig="parseOnLoad: true, debugAtAllCosts: true"> dojo.addOnLoad(function(){ // initialise and lay out home page console.log("Have a store:" + theStore); console.log("Have a structure:" + layout); var grid = new dojox.grid.DataGrid({ id:"grid", store : theStore, clientSort : "true", structure : layout }); grid.startup(); dojo.place(grid.domNode, dojo.body(), "first"); }); </script> The effect that I get is a completely empty rectangle is displayed. Using FireBug I can see that the DataGrid widget is created but that it has no rows or columns. So my guess is that the datastore or layout are not being passed correctly. However, it does appear that at the point of creation the values of theStore and layout are correct. Suggestions please, or indeed a working example of a programmic grid might solve the problem.

  • Jqplot ajax request

    - by Moozy
    I'm trying to do a dynamic content load for JQplot charts, but something is wrong: this is my javascript code: $(document).ready(function(){ var ajaxDataRenderer = function(url, plot, options) { var ret = null; $.ajax({ // have to use synchronous here, else the function // will return before the data is fetched async: false, url: url, dataType:"json", success: function(data) { ret = data; console.warn(data); } }); return ret; }; // The url for our json data var jsonurl = "getData.php"; var plot1 = $.jqplot('chart1', jsonurl, { title:'Data Point Highlighting', dataRenderer: ajaxDataRenderer, dataRendererOptions: { unusedOptionalUrl: jsonurl }, axes:{ xaxis: { renderer:$.jqplot.DateAxisRenderer, min: '11/01/2012', max: '11/30/2012', tickOptions:{formatString:'%b %#d'}, tickInterval:'5 days' }, yaxis:{ tickOptions:{ formatString:'%.2f' } } }, highlighter: { show: true, sizeAdjust: 7.5 }, cursor: { show: false } }); }); </script> and it is displaying the chart, but it is not displaying the values, looklike its not getting my data. output of: console.warn(data); is: [["11-01-2012",0],["11-02-2012",0],["11-03-2012",0],["11-04-2012",0],["11-05-2012",0],["11-06-2012",0],["11-07-2012",0],["11-08-2012",0],["11-09-2012",0],["11-10-2012",0],["11-11-2012",0],["11-12-2012",0],["11-13-2012",0],["11-14-2012",0],["11-15-2012",2],["11-16-2012",5],["11-17-2012",0],["11-18-2012",1],["11-19-2012",0],["11-20-2012",0],["11-21-2012",0],["11-22-2012",0],["11-23-2012",0],["11-24-2012",0],["11-25-2012",1],["11-26-2012",0],["11-27-2012",0],["11-28-2012",0],["11-29-2012",0],["11-30-2012",0]]

  • C# ASP.NET FILE TRANSFER FROM LOCAL MACHINE TO ANOTHER MACHINE

    - by Imcl
    I basically want to transfer a file from the client to the file storage server without actual login to the server so that the client cannot access the storage location on the server directly. I can do this only if i manually login to the storage server through windows login. I dont want to do that. This is a Web-Based Application. Using the link below, I wrote a code for my application. I am not able to get it right though, Please refer the link and help me ot with it... http://stackoverflow.com/questions/263518/c-uploading-files-to-file-server The following is my code:- protected void Button1_Click(object sender, EventArgs e) { filePath = FileUpload1.FileName; try { WebClient client = new WebClient(); NetworkCredential nc = new NetworkCredential(uName, password); Uri addy = new Uri("\\\\192.168.1.3\\upload\\"); client.Credentials = nc; byte[] arrReturn = client.UploadFile(addy, filePath); Console.WriteLine(arrReturn.ToString()); } catch (Exception ex) { Console.WriteLine(ex.Message); } } The following line doesn't execute... byte[] arrReturn = client.UploadFile(addy, filePath); THIS IS THE ERROR I GET :- "An exception occurred during a WebClient request"

  • Java's Scanner class: using left- and right buttons with Bash

    - by Bart K.
    I'm not too familiar with Linux/Bash, so I can't really find the right terms to search for. Take the snippet: public class Main { public static void main(String[] args) { java.util.Scanner keyboard = new java.util.Scanner(System.in); while(true) { System.out.print("$ "); String in = keyboard.nextLine(); if(in.equals("q")) break; System.out.println(" "+in); } } } If I run it on my Linux box using Bash, I can't use any of the arrow buttons (I'm only interested in the left- and right button, btw). For example, if I type "test" and then try to go back by pressing the left button, ^[[D appears instead of my cursor going back one place: $ test^[[D I've tried the newer Console class as well, but the end result is the same. On Windows' cmd.exe shell, I don't have this problem. So, the question is: is there a way to change my Java code so that I can use the arrow keys without Bash transforming them in sequences like ^[[D but actually move the cursor instead? I'm hoping that I can solve this on a "programming level". If this is not possible, then I guess I'd better try my luck on Superuser to see if there's something I need to change on my Bash console. Thanks in advance.

  • Issue with getting 2 chars from string using indexer

    - by Learner
    I am facing an issue in reading char values. See my program below. I want to evaluate an infix expression. As you can see I want to read '10' , '*', '20' and then use them...but if I use string indexer s[0] will be '1' and not '10' and hence I am not able to get the expected result. Can you guys suggest me something? Code is in c# class Program { static void Main(string[] args) { string infix = "10*2+20-20+3"; float result = EvaluateInfix(infix); Console.WriteLine(result); Console.ReadKey(); } public static float EvaluateInfix(string s) { Stack<float> operand = new Stack<float>(); Stack<char> operator1 = new Stack<char>(); int len = s.Length; for (int i = 0; i < len; i++) { if (isOperator(s[i])) // I am having an issue here as s[i] gives each character and I want the number 10 operator1.Push(s[i]); else { operand.Push(s[i]); if (operand.Count == 2) Compute(operand, operator1); } } return operand.Pop(); } public static void Compute(Stack<float> operand, Stack<char> operator1) { float operand1 = operand.Pop(); float operand2 = operand.Pop(); char op = operator1.Pop(); if (op == '+') operand.Push(operand1 + operand2); else if(op=='-') operand.Push(operand1 - operand2); else if(op=='*') operand.Push(operand1 * operand2); else if(op=='/') operand.Push(operand1 / operand2); } public static bool isOperator(char c) { bool result = false; if (c == '+' || c == '-' || c == '*' || c == '/') result = true; return result; } } }

  • How can I edit an exe's resources (File Description, Icon, etc.) using a command line utility?

    - by Coder7862396
    The whole story: I have created a fancy .NET program which has an installer created by the Visual Studio Installer (VSI). The VSI creates 2 files (setup.exe and MyProgramSetup.msi). I understand the reasons for both files being needed, however, I only want to distribute a SINGLE executable installer to users. I do not want them to see 2 files and have to choose between them. In order to do this I have merged the 2 files into a self-extracting archive using IExpress (as seen in this answer: http://stackoverflow.com/questions/535966/merge-msi-and-exe). This works well, however, the self-extracting archive that gets created has an ugly icon and confusing file info (the File Description is "Win32 Cabinet Self-Extractor" with 43 black spaces after it). I need to replace the icon with my custom one and change some of the file properties like "Description", "Company", etc. I would like to have this automatically done as a build step so having a program which is a command line/console utility would be great. I've searched for a while now and can only find one program which does exactly what I want (ResourceTuner Console: http://www.heaventools.com/command-line_resource_editor.htm) but it costs an arm and a leg and my budget is $0. Does anyone know a better way to achieve what I want, or know of a program which can replace an executable's resources without having to use a GUI? By the way, I have also tried "SiComponents Resource Builder 3" which can't even open the executable, and "Julien Audo's ResEdit" which just crashes when I execute the command: "resedit.exe -convert "Modified Resources.rc" "MyProgramSetup.exe"

  • "image contains error", trying to create and display images using google app engine

    - by bert
    Hello all the general idea is to create a galaxy-like map. I run into problems when I try to display a generated image. I used Python Image library to create the image and store it in the datastore. when i try to load the image i get no error on the log console and no image on the browser. when i copy/paste the image link (including datastore key) i get a black screen and the following message: The image “view-source:/localhost:8080/img?img_id=ag5kZXZ-c3BhY2VzaW0xMnINCxIHTWFpbk1hcBgeDA” cannot be displayed because it contains errors. the firefox error console: Error: Image corrupt or truncated: /localhost:8080/img?img_id=ag5kZXZ-c3BhY2VzaW0xMnINCxIHTWFpbk1hcBgeDA import cgi import datetime import urllib import webapp2 import jinja2 import os import math import sys from google.appengine.ext import db from google.appengine.api import users from PIL import Image #SNIP #class to define the map entity class MainMap(db.Model): defaultmap = db.BlobProperty(default=None) #SNIP class Generator(webapp2.RequestHandler): def post(self): #SNIP test = Image.new("RGBA",(100, 100)) dMap=MainMap() dMap.defaultmap = db.Blob(str(test)) dMap.put() #SNIP result = db.GqlQuery("SELECT * FROM MainMap LIMIT 1").fetch(1) if result: print"item found<br>" #debug info if result[0].defaultmap: print"defaultmap found<br>" #debug info string = "<div><img src='/img?img_id=" + str(result[0].key()) + "' width='100' height='100'></img>" print string else: print"nothing found<br>" else: self.redirect('/?=error') self.redirect('/') class Image_load(webapp2.RequestHandler): def get(self): self.response.out.write("started Image load") defaultmap = db.get(self.request.get("img_id")) if defaultmap.defaultmap: try: self.response.headers['Content-Type'] = "image/png" self.response.out.write(defaultmap.defaultmap) self.response.out.write("Image found") except: print "Unexpected error:", sys.exc_info()[0] else: self.response.out.write("No image") #SNIP app = webapp2.WSGIApplication([('/', MainPage), ('/generator', Generator), ('/img', Image_load)], debug=True) the browser shows the "item found" and "defaultmap found" strings and a broken imagelink the exception handling does not catch any errors Thanks for your help Regards Bert

  • Using "Object.create" instead of "new"

    - by Graham King
    Javascript 1.9.3 / ECMAScript 5 introduces Object.create, which Douglas Crockford amongst others has been advocating for a long time. How do I replace new in the code below with Object.create? var UserA = function(nameParam) { this.id = MY_GLOBAL.nextId(); this.name = nameParam; } UserA.prototype.sayHello = function() { console.log('Hello '+ this.name); } var bob = new UserA('bob'); bob.sayHello(); (Assume MY_GLOBAL.nextId exists). The best I can come up with is: var userB = { init: function(nameParam) { this.id = MY_GLOBAL.nextId(); this.name = nameParam; }, sayHello: function() { console.log('Hello '+ this.name); } }; var bob = Object.create(userB); bob.init('Bob'); bob.sayHello(); There doesn't seem to be any advantage, so I think I'm not getting it. I'm probably being too neo-classical. How should I use Object.create to create user 'bob'?

  • Is this a tableView issue or a CoreData Issue

    - by monotreme
    I have a CoreData-driven navigation app and I'm trying to figure out why It's crashing. I've got a hierarchy which is 3 view Controllers deep, all related by coredata relatioships, like this. TableViewA =relationship= TableViewB =relationship= TableViewC I'm honestly a novice at core data and I think my problem lies in the fetched results controller. I have one in TableViewA and another in TableViewB, and no matter how deep I go, the console always cites TableViewB's fetched results controller methods after a crash. Is this the problem? What's happening specifically is if I launch my app and drill down into the hierarchy of one record, let's call it Record1, I can delete sub records to my hearts content. Gone! no problem! But the second I go back to TableViewA and drill down into a different record, let's call that one Record2, and try to delete it's subrecords my app crashes, with the console citing this code from TableViewB as the problem. - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { // The fetch controller is about to start sending change notifications, so prepare the table view for updates. [self.tableView beginUpdates]; } When I go into the debugger, the specific method it always has a problem with is: if (![x.managedObjectContext save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } Just a confirmation of my idiocy with CoreData is all I'm looking for I think. Oh and how many ManagedObjectContexts should I have in an app of this type. I've been told I should have separate ones for adding content, which then should re-integrate into the main one. Is this true? Thanks!

  • How to write regex that searches for a dynamic amount of pairs?

    - by citronas
    Lets say a have a string such as this one: string txt = "Lore ipsum {{abc|prop1=\"asd\";prop2=\"bcd\";}} asd lore ipsum"; The information I want to extract "abc" and pairs like ("prop1","asd") , ("prop3", "bcd") where each pair used a ; as delimeter. Edit1: (based on MikeB's) code Ah, getting close. I found out how to parse the following: string txt = "Lore ipsum {{abc|prop1=\"asd\";prop2=\"http:///www.foo.com?foo=asd\";prop3=\"asd\";prop4=\"asd\";prop5=\"asd\";prop6=\"asd\";}} asd"; Regex r = new Regex("{{(?<single>([a-z0-9]*))\\|((?<pair>([a-z0-9]*=\"[a-z0-9.:/?=]*\";))*)}}", RegexOptions.Singleline | RegexOptions.IgnoreCase); Match m = r.Match(txt); if (m.Success) { Console.WriteLine(m.Groups["single"].Value); foreach (Capture cap in m.Groups["pair"].Captures) { Console.WriteLine(cap.Value); } } Question 1: How must I adjust the regex to say 'each value of a pair in delimited by \" only? I added chars like '.',';' etc, but I can't think of any char that I want to permit. The other way around would be much nicer. Question 2: How must I adjust this regex work with this thing here? string txt = "Lore ipsum {{abc|prop1=\"asd\";prop2=\"http:///www.foo.com?foo=asd\";prop3=\"asd\";prop4=\"asd\";prop5=\"asd\";prop6=\"asd\";}} asd lore ipsum {{aabc|prop1=\"asd\";prop2=\"http:///www.foo.com?foo=asd\";prop3=\"asd\";prop4=\"asd\";prop5=\"asd\";prop6=\"asd\";}}"; Therefore I'd probably try to get groups of {{...}} and use the other regex?

  • Pydev and Django: Shell not finding certain modules?

    - by Rosarch
    I am developing a Django project with PyDev in Eclipse. For a while, PyDev's Django Shell worked great. Now, it doesn't: >>> import sys; print('%s %s' % (sys.executable or sys.platform, sys.version)) C:\Python26\python.exe 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] >>> >>> from django.core import management;import mysite.settings as settings;management.setup_environ(settings) Traceback (most recent call last): File "<console>", line 1, in <module> ImportError: No module named mysite.settings >>> The dev server runs just fine. What could I be doing wrong? The models module is also conspicuously absent: >>> import mysite.myapp.models Traceback (most recent call last): File "<console>", line 1, in <module> ImportError: No module named mysite.myapp.models On the normal command line, outside of PyDev, the shell works fine. Why could this be happening?

  • How to pass filename to StandardInput (Process) in C#?

    - by Cosmo
    Hello Guys! I'm using the native windows application spamc.exe (SpamAssassin - sawin32) from command line as follows: C:\SpamAssassin\spamc.exe -R < C:\email.eml Now I'd like to call this process from C#: Process p = new Process(); p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardInput = true; p.StartInfo.FileName = @"C:\SpamAssassin\spamc.exe"; p.StartInfo.Arguments = @"-R"; p.Start(); p.StandardInput.Write(@"C:\email.eml"); p.StandardInput.Close(); Console.Write(p.StandardOutput.ReadToEnd()); p.WaitForExit(); p.Close(); The above code just passes the filename as string to spamc.exe (not the content of the file). However, this one works: Process p = new Process(); p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardInput = true; p.StartInfo.FileName = @"C:\SpamAssassin\spamc.exe"; p.StartInfo.Arguments = @"-R"; p.Start(); StreamReader sr = new StreamReader(@"C:\email.eml"); string msg = sr.ReadToEnd(); sr.Close(); p.StandardInput.Write(msg); p.StandardInput.Close(); Console.Write(p.StandardOutput.ReadToEnd()); p.WaitForExit(); p.Close(); Could someone point me out why it's working if I read the file and pass the content to spamc, but doesn't work if I just pass the filename as I'd do in windows command line?

  • Always get exception when trying to Fill data to DataTable

    - by Sambath
    The code below is just a test to connect to an Oracle database and fill data to a DataTable. After executing the statement da.Fill(dt);, I always get the exception "Exception of type 'System.OutOfMemoryException' was thrown.". Has anyone met this kind of error? My project is running on VS 2005, and my Oracle database version is 11g. My computer is using Windows Vista. If I copy this code to run on Windows XP, it works fine. Thank you. using System.Data; using Oracle.DataAccess.Client; ... string cnString = "data source=net_service_name; user id=username; password=xxx;"; OracleDataAdapter da = new OracleDataAdapter("select 1 from dual", cnString); try { DataTable dt = new DataTable(); da.Fill(dt); // Got error here Console.Write(dt.Rows.Count.ToString()); } catch (Exception e) { Console.Write(e.Message); // Exception of type 'System.OutOfMemoryException' was thrown. } Update I have no idea what happens to my computer.

  • Asynchronous crawling F#

    - by jlezard
    When crawling on webpages I need to be careful as to not make too many requests to the same domain, for example I want to put 1 s between requests. From what I understand it is the time between requests that is important. So to speed things up I want to use async workflows in F#, the idea being make your requests with 1 sec interval but avoid blocking things while waiting for request response. let getHtmlPrimitiveAsyncTimer (uri : System.Uri) (timer:int) = async{ let req = (WebRequest.Create(uri)) :?> HttpWebRequest req.UserAgent<-"Mozilla" try Thread.Sleep(timer) let! resp = (req.AsyncGetResponse()) Console.WriteLine(uri.AbsoluteUri+" got response") use stream = resp.GetResponseStream() use reader = new StreamReader(stream) let html = reader.ReadToEnd() return html with | _ as ex -> return "Bad Link" } Then I do something like: let uri1 = System.Uri "http://rue89.com" let timer = 1000 let jobs = [|for i in 1..10 -> getHtmlPrimitiveAsyncTimer uri1 timer|] jobs |> Array.mapi(fun i job -> Console.WriteLine("Starting job "+string i) Async.StartAsTask(job).Result) Is this alright ? I am very unsure about 2 things: -Does the Thread.Sleep thing work for delaying the request ? -Is using StartTask a problem ? I am a beginner (as you may have noticed) in F# (coding in general actually ), and everything envolving Threads scares me :) Thanks !!

  • log4js ConsoleAppender initialization

    - by perrierism
    I'm wondering if anyone happens to have some experience using Log4js? It seems its normal ConsoleAppender isn't always ready to use immediately after it's added to a logger object... If I have two sequential script tags in a document like: //Initialize logger <script type="text/javascript"> var logger = new Log4js.getLogger("JSLOG"); logger.addAppender(new Log4js.ConsoleAppender(logger, false)); logger.setLevel(Log4js.Level.INFO); </script> //Use logger <script type="text/javascript"> logger.info('Test test'); </script> ... It causes the console pop-up (pop-up window) to appear with an error message on page load: 12:58:23 PM WARN Log4js - Could not run the listener function () { return fn.apply(object, arguments); }. TypeError: this.outputElement is null The console is still initialised, it's there afterward, but for just that first logger call it doesn't seem to be there fully. If I make the first logger call setTimeout("logger.info('test test')", 1000), it doesn't have the error. So it's like it's not ready immediately. Anyone see this before or know what a workaround might be? Cheers

  • jQuery, unable to store data returned by $.get function.

    - by Deepak Prasanna
    I am trying to turn div#sidebar into a sidebar in my app. My code looks like the one below. $('#sidebar').userProfile(); jQuery.fn.userProfile = function() { $.get('/users/profile', function(data){ $(this).html(data); }); }; It didnt work because, I found the this (inside the $.get function) here contexts to the get request and not $('#sidebar'). Then I tried something like below. $('#sidebar').userProfile(); #This doesnot work jQuery.fn.userProfile = function() { var side_bar = null; $.get('/users/profile', function(data){ side_bar = data; }); $(this).html(side_bar); console.log(side_bar); }; This doesnt work either. In firebug console I see Null which I am setting on top when I am declaring the variable.Atlast I made it work by changing my code to something like below by hardcoding the selector. #This works, but I cannot turn any element to a sidebar which is sick. jQuery.fn.userProfile = function() { $.get('/users/profile', function(data){ $('#sidebar').html(data); }); }; But this is not I wanted because I wanted to turn any element to a sidebar. Where am I goin wrong or which is the correct way of doing it?

  • .NET 4: Process.Start using credentials returns empty output

    - by alexey
    I run an external program from ASP.NET: var process = new Process(); var startInfo = process.StartInfo; startInfo.FileName = filePath; startInfo.Arguments = arguments; startInfo.UseShellExecute = false; startInfo.RedirectStandardOutput = true; startInfo.RedirectStandardError = true; process.Start(); process.WaitForExit(); Console.Write("Output: {0}", process.StandardOutput.ReadToEnd()); Console.Write("Error Output: {0}", process.StandardError.ReadToEnd()); Everything works fine with this code: the external program is executed and process.StandardOutput.ReadToEnd() returns the correct output. But after I add these two lines before process.Start() (to run the program in the context of another user account): startInfo.UserName = userName; startInfo.Password = securePassword; The program is not executed and process.StandardOutput.ReadToEnd() returns an empty string. No exceptions are thrown. userName and securePassword are correct (in case of incorrect credentials an exception is thrown). How to run the program in the context of another user account?

  • Trying to Use LoadMoreElement in Monotouch.Dialog

    - by user1487581
    I am using Monotouch to write an Ipad app. The app uses tables to browse down through a directory tree and then select a file. I have used Monotouch.Dialog to browse the directories and I set up the directory tables as the app starts.However there are too many files to set up in a table as the app starts and so I want to set up the 'file table' as the file is selected from the lowest level directory table. I am trying to use LoadMoreElement to do this but I cannot make it work or find any examples online. I have coded the 'Elements API Walkthrough' in the Xamarin tutorial at:- http://docs.xamarin.com/ios/tutorials/MonoTouch.Dialog I then add a new section to the code:- _addButton.Clicked += (sender, e) => { ++n; var task = new Task{Name = "task " + n, DueDate = DateTime.Now}; var taskElement = new RootElement (task.Name){ new Section () { new EntryElement (task.Name, "Enter task description", task.Description) }, new Section () { new DateElement ("Due Date", task.DueDate) }, new Section() { new LoadMoreElement("Passive","Active", delegate {MyAction();}) } }; _rootElement [0].Add (taskElement); Where MyAction is:- public void MyAction() { Console.WriteLine ("we have been actioned"); } The problem is that MyAction is triggered and Console.Writeline writes the message but the table stays in the active state and never returns to passive. the documentation says:- Once your code in the NSAction is finished, the UIActivity indicator stops animating and the normal caption is displayed again. What am I missing? Ian

  • WCF Callbacks often break

    - by cdecker
    I'm having quite some trouble with the WCF Callback mechanism. They sometimes work but most of the time they don't. I have a really simple Interface for the callbacks to implement: public interface IClientCallback { [OperationContract] void Log(string content); } I then implmenent that interface with a class on the client: [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] [ServiceContract] internal sealed class ClientCallback : IClientCallback { public void Log(String content){ Console.Write(content); } } And on the client I finally connect to the server: NetTcpBinding tcpbinding = new NetTcpBinding(SecurityMode.Transport); EndpointAddress endpoint = new EndpointAddress("net.tcp://127.0.0.1:1337"); ClientCallback callback= new ClientCallback(); DuplexChannelFactory<IServer> factory = new DuplexChannelFactory<IServer>(callback,tcpbinding, endpoint); factory.Open(); _connection = factory.CreateChannel(); ((ICommunicationObject)_connection).Faulted += new EventHandler(RecreateChannel); try { ((ICommunicationObject)_connection).Open(); } catch (CommunicationException ce) { Console.Write(ce.ToString()); } To invoke the callback I use the following: OperationContext.Current.GetCallbackChannel().Log("Hello World!"); But it just hangs there, and after a while the client complains about timeouts. Is there a simple solution as to why?

  • ShSetFolderPath works on win7, doesn't on XP

    - by pipboy3k
    Hey. I'm trying to use ShSetFolderPath function in C#. I work on Win7, I've managed to use ShSetKnownFolderPath and it works fine. Since this function is unavaible in WinXP, i tried to invoke ShSetFolderPath. Because i'm not familiar with invoking, I've done some searching and found something on some French forum. I don't speak French, but this declaration makes sense (as written in Remarks of function documentation in MSDN library): [DllImport( "Shell32.dll", CharSet = CharSet.Unicode, EntryPoint = "#232" ) ] private static extern int SHSetFolderPath( int csidl, IntPtr hToken, uint flags, string path ); I call it like that: private static int CSIDL_DESKTOP = 0x0000; public static void SetDesktopPath(string path) { int ret; ret = SHSetFolderPath(CSIDL_DESKTOP, IntPtr.Zero, 0, path); if (ret != 0) { Console.WriteLine(ret); Console.WriteLine(Marshal.GetExceptionForHR(ret)); } } It works in Win7, but in XP function returns -2147024809, which means "Value does not fall within the expected range". My guess is, it's something wrong with Dll importing. Any idea?

  • jquery ready function: script not detecting a function

    - by deostroll
    There is a web page with place holder (a normal div). Via ajax calls I am loading a <form> and a <script> into the place holder. The script contains necessary javascript to initialize the form (i.e. for e.g. disable the controls so as to make form read-only, etc). Here is a piece of code I have; it works, but the commented part doesn't work. Because the script engine cannot find the object tristate_DisableControl which is a function in one of those scripts I call via ajax. $(document).ready(function() { // $('#site_preferences_content div').each(function() { // if (typeof (window.tristate_DisableControl) == 'undefined') { // if (typeof (window.console) != 'undefnied') // console.log((new Date()).toTimeString() + ' not logable'); // pausecomp(1000); // } // else // tristate_DisableControl(this); // }); //end $('#site_prefrences_content div').each() setTimeout(function() { $('#site_preferences_content div').each(function() { tristate_DisableControl(this); }) }, 1000); }); I thought by the time $(document).ready() executes the DOM will be properly loaded...

  • Microsoft Solver Foundation constraint

    - by emaster70
    Hello, I'm trying to use Microsoft Solver Foundation 2 to solve a fairly complicated situation, however I'm stuck with an UnsupportedModelException even when I dumb down the model as much as possible. Does anyone have an idea of what I'm doing wrong? Following is the least example required to reproduce the problematic behavior. var ctx = SolverContext.GetContext(); var model = ctx.CreateModel(); var someConstant = 1337.0; var decisionA = new Decision(Domain.Real, "decisionA"); var decisionB = new Decision(Domain.Real, "decisionB"); var decisionC = new Decision(Domain.Real, "decisionC"); model.AddConstraint("ca", decisionA <= someConstant); model.AddConstraint("cb", decisionB <= someConstant); model.AddConstraint("cc", decisionC <= someConstant); model.AddConstraint("mainConstraint", Model.Equal(Model.Sum(decisionA, decisionB, decisionC), someConstant)) model.AddGoal("myComplicatedGoal", GoalKind.Minimize, decisionC); var solution = ctx.Solve(); solution.GetReport().WriteTo(Console.Out); Console.ReadKey(); Please consider that my actual model should include, once complete, a few constraints in the form of a*a+b*a <= someValue, so if what I'm willing to do ultimately isn't supported, please let me know in advance. If that's the case I'd also appreciate a suggestion of some other solver with a .NET friendly interface that I could use (only well-known commercial packages, please). Thanks in advance
