I mean the height I set was 80 but it was not set as 80 height. How can I make it. Thank You

  • Catching exception in Main() method

    - by Corvin
    Consider the following simple application: a windows form created by a "new C# windows application" sequence in VS that was modified in a following way: public static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); try { Application.Run(new Form1()); } catch (Exception ex) { MessageBox.Show("An unexpected exception was caught."); } } Form1.cs contains the following modifications: private void Form1_Load(object sender, EventArgs e) { throw new Exception("Error"); } If I press F5 in IDE, then, as I expect, I see a message box saying that exception was caught and the application quits. If I go to Debug(or Release)/bin and launch the executable, I see the standard "Unhandled exception" window, meaning that my exception handler doesn't work. Obviously, that has something to do with exception being thrown from a different thread that Application.Run is called from. But the question remains - why the behavior differs depending on whether the application has been run from IDE or from command line? What is the best practice to ensure that no exceptions remain unhandled in the application?

  • Unit Testing an Event Firing From a Thread

    - by Dougc
    I'm having a problem unit testing a class which fires events when a thread starts and finishes. A cut down version of the offending source is as follows: public class ThreadRunner { private bool keepRunning; public event EventHandler Started; public event EventHandler Finished; public void StartThreadTest() { this.keepRunning = true; var thread = new Thread(new ThreadStart(this.LongRunningMethod)); thread.Start(); } public void FinishThreadTest() { this.keepRunning = false; } protected void OnStarted() { if (this.Started != null) this.Started(this, new EventArgs()); } protected void OnFinished() { if (this.Finished != null) this.Finished(this, new EventArgs()); } private void LongRunningMethod() { this.OnStarted(); while (this.keepRunning) Thread.Sleep(100); this.OnFinished(); } } I then have a test to check that the Finished event fires after the LongRunningMethod has finished as follows: [TestClass] public class ThreadRunnerTests { [TestMethod] public void CheckFinishedEventFiresTest() { var threadTest = new ThreadRunner(); bool finished = false; object locker = new object(); threadTest.Finished += delegate(object sender, EventArgs e) { lock (locker) { finished = true; Monitor.Pulse(locker); } }; threadTest.StartThreadTest(); threadTest.FinishThreadTest(); lock (locker) { Monitor.Wait(locker, 1000); Assert.IsTrue(finished); } } } So the idea here being that the test will block for a maximum of one second - or until the Finish event is fired - before checking whether the finished flag is set. Clearly I've done something wrong as sometimes the test will pass, sometimes it won't. Debugging seems very difficult as well as the breakpoints I'd expect to be hit (the OnFinished method, for example) don't always seem to be. I'm assuming this is just my misunderstanding of the way threading works, so hopefully someone can enlighten me.

  • Passing a outside variable into a <asp:sqldatasource> tag. ASP.NET 2.0

    - by MadMAxJr
    I'm designing some VB based ASP.NET 2.0, and I am trying to make more use of the various ASP tags that visual studio provides, rather than hand writing everything in the code-behind. I want to pass in an outside variable from the Session to identify who the user is for the query. <asp:sqldatasource id="DataStores" runat="server" connectionstring="<%$ ConnectionStrings:MY_CONNECTION %>" providername="<%$ ConnectionStrings:MY_CONNECTION.ProviderName %>" selectcommand="SELECT THING1, THING2 FROM DATA_TABLE WHERE (THING2 IN (SELECT THING2 FROM RELATED_DATA_TABLE WHERE (USERNAME = @user)))" onselecting="Data_Stores_Selecting"> <SelectParameters> <asp:parameter name="user" defaultvalue ="" /> </SelectParameters> </asp:sqldatasource> And on my code behind I have: Protected Sub Data_Stores_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles Data_Stores.Selecting e.Command.Parameters("user").Value = Session("userid") End Sub Oracle squaks at me with ORA-01036, illegal variable name. Am I declaring the variable wrong in the query? I thought external variables share the same name with a @ prefixed. from what I understand, this should be placing the value I want into the query when it executes the select. EDIT: Okay, thanks for the advice so far, first error was corrected, I need to use : and not @ for the variable declaration in the query. Now it generates an ORA-01745 invalid host/bind variable name. EDIT AGAIN: Okay, looks like user was a reserved word. It works now! Thanks for other points of view on this one. I hadn't thought of that approach.

  • Silverlight 4 webclient authentication - anyone have this working yet?

    - by Toran Billups
    So one of the best parts about the new Silverlight 4 beta is that they finally implemented the big missing feature of the networking stack - Network Credentials! In the below I have a working request setup, but for some reason I get a "security error" when the request comes back - is this because twitter.com rejected my api call or something that I'm missing in code? It might be good to point out that when I watch this code execute via fiddler it shows that the xml file for cross domain is pulled down successfully, but that is the last request shown by fiddler ... public void RequestTimelineFromTwitterAPI() { WebRequest.RegisterPrefix("https://", System.Net.Browser.WebRequestCreator.ClientHttp); WebClient myService = new WebClient(); myService.AllowReadStreamBuffering = true; myService.UseDefaultCredentials = false; myService.Credentials = new NetworkCredential("username", "password"); myService.UseDefaultCredentials = false; myService.OpenReadCompleted += new OpenReadCompletedEventHandler(TimelineRequestCompleted); myService.OpenReadAsync(new Uri("https://twitter.com/statuses/friends_timeline.xml")); } public void TimelineRequestCompleted(object sender, System.Net.OpenReadCompletedEventArgs e) { //anytime I query for e.Result I get a security error }

  • How do I load PersistentDocuments into the same window

    - by Brad Stone
    I want to open NSPersistentDocuments and load them into the same window one at a time. I'm almost there but missing some steps. Hopefully someone can help me. I have a few saved documents on the hard drive. On launch my app opens to an untitled NSPersistentDocument and creates a separate NSWindowController. When I press the button to load file 1 off the hard drive the data appears in the fields but two things are wrong that I can see: 1) changing the data doesn't make the document dirty 2) choosing save updates the persistentstore (I know this because when I open the file again I see the changes) but I get an error: +entityForName: could not locate an NSManagedObjectModel for entity name 'Book' Here's my code which is in the WindowController that was launched initially with the untitled document. This code isn't perfect. For example, I know I should processPendingChanges and save the current doc before I load the new one. This is test code to try to get over this hurdle. - (IBAction)newBookTwo:(id)sender { NSDocumentController *dc = [NSDocumentController sharedDocumentController]; NSURL *url = [NSURL fileURLWithPath:[@"~/Desktop/File 2.binary" stringByExpandingTildeInPath]]; NSError *error; MainWindowDocument *thisDoc = [dc openDocumentWithContentsOfURL:url display:NO error:&error]; [self setDocument:thisDoc]; [self setManagedObjectContext:[thisDoc managedObjectContext]]; } Thanks!

    - by tcornelis
    I have been looking for an answer for almost a week now, but having read all the stackoverflow items i can't seem to find a solution that is working for me. The error that i'm having is : Port: Could not establish connection. Receiving end does not exist. lastError:30 set lastError:30 dispatchOnDisconnect messaging:277 folder layout : img developer_icon.png js sidebar.js main.js jquery-2.0.3.js manifest.json my the manifest.json file looks something like this (it is version 2) :` "browser_action": { "default_icon": "./img/developer_icon.png" }, "content_scripts": [ { "matches": ["*://*/*"], "js": ["./js/sidebar.js"], "run_at": "document_end" } ], "background" : { "scripts" : ["./js/main.js","./js/jquery-2.0.3.js"] }, I want to handle the user clicking the extension icon so i could inject a sidebar in the existing website (because the extension i would like to develop requires that amount of space). So in main.js : chrome.browserAction.onClicked.addListener(function(tab) { chrome.tabs.getSelected(null, function(tab){ chrome.tabs.sendMessage( //Selected tab id tab.id, //Params inside a object data {callFunction: "toggleSidebar"}, //Optional callback function function(response) { console.log(response); } ); }); }); and in sidebar.js : chrome.runtime.onMessage.addListener(function(req,sender,sendResponse){ console.log("sidebar handling request"); toggleSidebar(); }); but i'm never able to see the console.log in my console because of the error. Does someone know what i did wrong? Thanks in advance!

  • EF in a UserControl can't see the app.config?

    - by Sven
    I just created a user control. This control also makes use of my static Entity Framework class to load two comboboxes. All is well and runs without a problem. Design and runtime are working. Then when I stop the application all the forms that contain my UserControl don't work any more in design time. I just see two errors: Error1: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. Error 2: The variable ccArtikelVelden is either undeclared or was never assigned. (ccArtikelVelde is my UserControl) Runtime everything is still working My static EF Repositoy class: public class BSManagerData { private static BSManagerEntities _entities; public static BSManagerEntities Entities { get { if (_entities == null) _entities = new BSManagerEntities(); return _entities; } set { _entities = value; } } } Some logic happening in my UserControl to load the data in the comboboxes: private void LaadCbx() { cbxCategorie.DataSource = (from c in BSManagerData.Entities.Categories select c).ToList(); cbxCategorie.DisplayMember = "Naam"; cbxCategorie.ValueMember = "Id"; } private void cbxCategorie_SelectedIndexChanged(object sender, EventArgs e) { cbxFabrikant.DataSource = from f in BSManagerData.Entities.Fabrikants where f.Categorie.Id == ((Categorie)cbxCategorie.SelectedItem).Id select f; cbxFabrikant.DisplayMember = "Naam"; cbxFabrikant.ValueMember = "Id"; } The only way to make my forms work again, design time, is to comment out the EF part in the UserControl (see above) and rebuild. It's very strange, everything is in the same assembly, same namespace (for the sake of simplicity). Anyone an idea?

  • draw rectangle in millimeters doesnt show accurate width

    - by user338081
    I am drawing a rectangle in millimeter on a panel using the following code in c# by entering the width and length in mm at runtime. however the resultant rectangle drawn varies in size in different monitors. I want the rectangle to appear same size irrespective of the running the app in any monitor. Can any1 help me?. currently the width for 10mm measures 12mm and length for 10mm shows 11mm using a scale. I tested the appn on different monitors, there again it shows different length. Is ther anyway that i can show it to be of same width and length? void panel1_Paint(object sender, PaintEventArgs e) { SolidBrush ygBrush = new SolidBrush(Color.YellowGreen); g = panel1.CreateGraphics(); g.PageUnit = GraphicsUnit.Millimeter; int w = Int32.Parse(textBox1.Text.ToString()); int h = Int32.Parse(textBox2.Text.ToString()); rct = new Rectangle(94, 27, w, h); g.FillRectangle(ygBrush, rct); }

  • How to reload a tableView i.e call the viewDidLoad method if a condition is met

    - by Kquane Ingram
    The problem is this i need a way to basically erase all the entry data a user placed into my arrays if a condition is met. Im new to Objective-C and iOS programming, but i believed the solution might be in calling the viewDidLoad method, thus it would virtually refresh the applications with the values of the array reset to default. If there is any other logical way of doing this i would appreciate the help. In short i need to refresh the arrays as they were when the application first launched and the user did not select anything. This is the part where i need it to refresh. if ([gradeRecieved objectAtIndex:i]==nil) { break; // if this condition is met the program must begin anew. Edit* I need to recall the - (void)viewDidLoad method here is more of the code. -(IBAction)button:(id)sender{ int i = 0; int sum = 0; int gradeEarned; int creditHours = 3; for ( i=0;i<8 ; i++) { if ([[points objectAtIndex:i] tag]==GradeA.intValue) { [gradeRecieved replaceObjectAtIndex:i withObject:GradeA]; } if ([[points objectAtIndex:i]tag]==GradeB.intValue) { [gradeRecieved replaceObjectAtIndex:i withObject:GradeB]; } if ([[points objectAtIndex:i]tag]==GradeC.intValue){ [gradeRecieved replaceObjectAtIndex:i withObject:GradeC]; } if ([gradeRecieved objectAtIndex:i]==nil) { break; // if this condition is met the program must restart. } } while ( i<[gradeRecieved count]) { if ([gradeRecieved objectAtIndex:i] == GradeA ) { [finArray replaceObjectAtIndex:i withObject:GradeA]; i++; continue; } if ([gradeRecieved objectAtIndex:i] == GradeB ) { [gradeRecieved replaceObjectAtIndex:i withObject:GradeB]; i++; continue; } if ([gradeRecieved objectAtIndex:i] == GradeC ) { [gradeRecieved replaceObjectAtIndex:i withObject:GradeC]; i++; continue; } }

  • How to write to a Text File in Pipe delimited format from MS Sql Server / ASP.Net?

    - by NJTechGuy
    I have a text file which needs to be constantly updated (regular intervals). All I want is the syntax and possibly some code that outputs data from a MS Sql Database using ASP.Net. The code I have so far is : <%@ Import Namespace="System.IO" %> <script language="vb" runat="server"> sub Page_Load(sender as Object, e as EventArgs) Dim FILENAME as String = Server.MapPath("Output.txt") Dim objStreamWriter as StreamWriter ' If Len(Dir$(FILENAME)) > 0 Then Kill(FILENAME) objStreamWriter = File.AppendText(FILENAME) objStreamWriter.WriteLine("A user viewed this demo at: " & DateTime.Now.ToString()) objStreamWriter.Close() Dim objStreamReader as StreamReader objStreamReader = File.OpenText(FILENAME) Dim contents as String = objStreamReader.ReadToEnd() lblNicerOutput.Text = contents.Replace(vbCrLf, "<br>") objStreamReader.Close() end sub </script> <asp:label runat="server" id="lblNicerOutput" Font-Name="Verdana" /> With PHP, it is a breeze, but with .Net I have no clue. If you could help me with the database connectivity and how to write the data in pipe delimited format to an Output.txt file, that had be awesome. Thanks guys!

  • Silverlight Timer problem

    - by jose
    Hello, I am developing a Silverlight application with custom animations. I want to update the variable animationCounter every 1 milissecond, so that in one second the value is 1000. I've tried DispatcherTimer and System.Threading.Timer. this way: DispatcherTimer timer = new DispatcherTimer(); (...) timer.Interval = new TimeSpan(0, 0, 0, 0, 1); timer.Tick += new EventHandler(timer_Tick); (...) (...) void timer_Tick(object sender, EventArgs e) { animationCounter++; Dispatcher.BeginInvoke(() => txtAnimationCounter.Text = animationCounter.ToString()); } with System.Threading.Timer System.Threading timer = null; timer = new System.Threading.Timer(UpdateAnimationCounter, 0, 1); void UpdateAnimationCounter(object state) { animationCounter++; Dispatcher.BeginInvoke(() => txtAnimationCounter.Text = animationCounter.ToString()); } Both of them are setting AnimationCounter around 100 in one second. Should be 1000. I don't know why. Is there anything I'm missing. Thanks

  • In Silverlight 3 how can I get the call to HtmlPage.Plugin.SetStyleAttribute() call to call other co

    - by John Rennemeyer
    I'm trying to take a snapshot of my Silverlight control using WriteableBitmap and it works fine, however, it only takes a snapshot of what is showing. I'm trying to resize the Silverlight control so it will show everything and then take a screenshot, however, the code doesn't resize the control until after the code after the call all runs which is the snapshot code... I can get this work using a timer to fire the snapshot after the other code has caused the resize but I'm wondering if there is a better way. The HtmlPage.Plugin.SetStyleAttribute call has to be called from the UI thread so I'm assuming that's where the problem is. The fact that it is being dispatched onto the UI thread while the rest of the code is not and so the other code is being run first. Is there anyway to create a new event or attach to the call to determine when it has been run to then fire off my snapshot code? I have the following code: private void btnTakeSnapshot_Click(object sender, System.Windows.RoutedEventArgs e) { if (CurrentContractAction != null) { string heightBefore = HtmlPage.Plugin.GetStyleAttribute("height"); HtmlPage.Plugin.SetStyleAttribute("height", string.Format("{0}px", "1800")); //this line doesn't change the height until after the "TakeSnapshot" code is run for some reason, I'm thinking it is because it is most likely dispatched to the UI thread :( and the following code is not run on the UI thread Snapshot snapshot = new Snapshot(string.Format("Action_Schedule_{0}", CurrentContractAction.Title), LayoutRoot, LayoutRoot, busyIndicatorDataGrid); snapshot.HideElements(btnViewGanttChart, btnSave, btnEditAction, btnFullScreen, btnTakeSnapshot, btnLockAndSubmit); snapshot.TakeSnapshot(); snapshot.ResetElementsVisibility(); HtmlPage.Plugin.SetStyleAttribute("height", string.Format("{0}px", heightBefore)); } } Thanks, John

  • No event is firing when placing a custom data bound control in DataRepeater control in Windows forms

    - by Remo
    Hi, Custom events in a custom data bound control are not firing in DataRepeater control. When I debug it I found that the DataRepeater Control recreates the control using Activator.CreateInstance and Copies the Properties and Events. In my case copying events doesn't copy the custom events that I hooked in. For example public class MyClass : Control { public event EventHandler MyEvent; protected virtual void OnMyEvent() { if(this.MyEvent != null) { this.MyEvent(this,EventArgs.Empty); } } private int selectedIndex= -1; public int SelectedIndex { get { return this.selectedIndex; } set { if(this.selectedIndex != value) { this.selectedIndex = value; this.OnMyEvent(); } } } // // DataBinding stuff goes here // } public Form1() { InitialiseComponent(); ArrayList list = new ArrayList(); list.Add("one"); this.dataRepeater1.DataSource = list; // One Repeater MyClass test = new Myclass(); test.DataSource = GetDataTable(); this.dataRepeater1.ItemTemplate.Controls.Add(test); test.MyEvent +=new EventHandler(test_MyEvent); } // This Event should fire when selected index of Datatable is changed and is firing when placed directly in the form and not firing when place in DataRepeater control/////////////////////// private void test_MyEvent(object sender, EventArgss e) { // This event is not fired/////////////////////// } private DataTable GetDataTable() { ..// Create a data Table and return } Any help Appreciated.

  • How to mix Grammer (Rules) & Dictation (Free speech) with SpeechRecognizer in C#

    - by Lee Englestone
    I really like Microsofts latest speech recognition (and SpeechSynthesis) offerings. http://msdn.microsoft.com/en-us/library/ms554855.aspx http://estellasays.blogspot.com/2009/04/speech-recognition-in-cnet.html However I feel like I'm somewhat limited when using grammers. Don't get me wrong grammers are great for telling the speech recognition exactly what words / phrases to look out for, however what if I want it to recognise something i've not given it a heads up about? Or I want to parse a phrase which is half pre-determined command name and half random words? For example.. Scenario A - I say "Google [Oil Spill]" and I want it to open Google with search results for the term in brackets which could be anything. Scenario B - I say "Locate [Manchester]" and I want it to search for Manchester in Google Maps or anything else non pre-determined I want it to know that 'Google' and 'Locate' are commands and what comes after it are parameters (and could be anything). Question : Does anyone know how to mix the use of pre-determined grammers (words the speech recognition should recognise) and words not in its pre-determined grammer? Code fragments.. using System.Speech.Recognition; ... ... SpeechRecognizer rec = new SpeechRecognizer(); rec.SpeechRecognized += rec_SpeechRecognized; var c = new Choices(); c.Add("search"); var gb = new GrammarBuilder(c); var g = new Grammar(gb); rec.LoadGrammar(g); rec.Enabled = true; ... ... void rec_SpeechRecognized(object sender, SpeechRecognizedEventArgs e) { if (e.Result.Text == "search") { string query = "How can I get a word not defined in Grammer recognised and passed into here!"; launchGoogle(query); } } ... ... private void launchGoogle(string term) { Process.Start("IEXPLORE", "google.com?q=" + term); }

  • Update PageTitle on Timer.Tick

    - by sohum
    I've got a page with a Timer that is being used as a trigger on an UpdatePanel. The page also contains a TabContainer and several TabPanels. Look at this question for more information. Basically, I've got an UpdatePanel as the element in each TabPanel's ContentTemplate, and the UpdatePanel is triggered by the Timer. My page displays data by reading a database on each tick. I've got the following code running on each Timer.Tick in my codebehind: protected void timeRefresher_Tick(object sender, EventArgs e) { UpdateLivePageTitle(); } The UpdateLivePageTitle() function reads the new information from the database and sets Page.Title accordingly. However, this information is of course not sent to the browser because there is no full page postback--only an async postback to the update panels. As a result, my page title is not being updated until the whole page is being posted back, which destroys the purpose of using UpdatePanels in the first place. I figure there would be a way to do this by using the document.title JS element and call that from within UpdateLivePageTitle(). But as of now, I haven't been able to figure out how to do this. I tried using the following in my UpdateLivePageTitle() function: string updatePageTitleScript = String.Format("document.title = '{0}'", newPageTitle); ToolkitScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "UpdatePageTitle", updatePageTitleScript, true); But the result of this was that my TabContainer stopped rendering. I'm also not sure that would work with the async partial page postbacks, either. Any ideas? Thanks!

  • ASP .NET Added Event Handlers to buttons on Page_Load. Event handlers do not fire the first click, b

    - by John
    Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface. Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work. I placed breakpoints at the the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers are triggered. On the second click, they are triggered. Any ideas? Example of Button Definition Button btn = new Button(); btn.Text = "Click Me Locked Screen"; bth.Click += new EventHandler(Btn_Click); Example of Event Handler Method Definition void Btn_Click(object sender, EventArgs e) { // Do Something }

  • WindowsFormsApplicationBase SplashScreen makes login form ignore keypresses until I click on it - how to debug?

    - by Tom Bushell
    My WinForms app has a simple modal login form, invoked at startup via ShowDialog(). When I run from inside Visual Studio, everything works fine. I can just type in my User ID, hit the Enter key, and get logged in. But when I run a release build directly, everything looks normal (the login form is active, there's a blinking cursor in the User ID MaskedEditBox), but all keypresses are ignored until I click somewhere on the login form. Very annoying if you are used to doing everything from the keyboard. I've tried to trace through the event handlers, and to set the focus directly with code, to no avail. Any suggestions how to debug this (outside of Visual Studio), or failing that - a possible workaround? Edit Here's the calling code, in my Main Form: private void OfeMainForm_Shown(object sender, EventArgs e) { OperatorLogon(); } private void OperatorLogon() { // Modal dialogs should be in a "using" block for proper disposal using (var logonForm = new C21CfrLogOnForm()) { var dr = logonForm.ShowDialog(this); if (dr == DialogResult.OK) SaveOperatorId(logonForm.OperatorId); else Application.Exit(); } } Edit 2 Didn't think this was relevant, but I'm using Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase for it's splash screen and SingleInstanceController support. I just commented out the splash screen code, and the problem has disappeared. So that's opened up a whole new line of inquiry... Edit 3 Changed title to reflect better understanding of the problem

  • iPhone dev: UIBarButtonItem or title not showing up in NavigationBar

    - by IceMan85
    Hello everyone, here my problem. I have a NavigationBar at the top, a TabBar at the bottom and a TableView at the center of the screen. Very normal situation. I set it all up in IB and I have set this in the app delegate : ExpensesListNavController *expensesListNavController; This in order to be able to add new views to the stack. I need to have 3 levels: - list of items in a TableView - OK - firstLevel: once pressed one cell a view is added to the stack - OK - second level: one pressed the "modify" button on the navBar on the firstLevel I want to show a new view that can be customized by the user. My Problem is coming when trying to add the "Modify" button in the "firstLevelView". Here-below my code -(IBAction) modify:(id)sender { if (editableDetailViewController == nil) { editableDetailViewController = [[editableDetailViewController alloc] init]; } editableDetailViewController.expense = expense; [appDelegate.expensesListNavController pushViewController:editableDetailViewController animated:YES]; editableDetailViewController = nil; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; appDelegate = [[UIApplication sharedApplication] delegate]; UIBarButtonItem *modifyButton = [[UIBarButtonItem alloc] initWithTitle:@"Modify" style:UIBarButtonItemStylePlain target:self action:@selector(modify:)]; appDelegate.expensesListNavController.navigationItem.rightBarButtonItem = modifyButton; appDelegate.expensesListNavController.navigationItem.title = @"Titoloooo"; NSLog(@"NavBar button has just been set !!"); [modifyButton release]; Nothing is being showed, neither title nor the button. Do you have any idea of what is happening ?? I really cannot figure out !!! Thanks a lot in advance, AM
