  • Drawing a relative line in C#

    - by icemanind
    Guys, I know this is going to turn out to be a simple answer, but I can't seem to figure it out. I have a C# Winform application that I am trying to build. I am trying to draw a white line 60 pixels above the bottom of the form. I am using this code: private void MainForm_Paint(object sender, PaintEventArgs e) { e.Graphics.DrawLine(Pens.White, 10, this.Height-60, 505, this.Height-60); } Simple enough, however no line is drawn. After some debugging, I figured out that it IS drawing the line, but it is drawing it outside my form. If I change the -60 to -175, then I can see it at the bottom of my form. This would solve my problem, except as my form's height changes, the line draws closer and closer to the bottom of my form until eventually, its off the form again. What am I doing wrong? Am I using the wrong graphics unit? Or is there a more complex calculation I need to do to determine 60 pixels from the bottom of my form?

  • compiling and running java on windows

    - by artur grzesiak
    I thought the task should be fairly easy, but my understanding of javac and java in general is rather poor. I am using Windows8 and would like to compile a single file.java that makes use of other classes. I successfully (at least without any warnings) compiled my file by calling: javac -cp relative_path_to_needed_classes relative_path_to_file_java\file.java Now if I want to run the result of compilation (file.class) by calling: java -cp relative_path_to_needed_classes relative_path_to_file_java\file I get: Error: Could not find or load main class relative_path_to_file_java\file I was trying a lot of combination to modify the -cp (eg. by adding .\;relative_path_to_file;) but still the closest where I get is: Exception in thread "main" java.lang.NoClassDefFoundError : relative_path_to_file\file (wrong name: file) The file from (wrong name: file) is the name of the file and the name of the public class within the file. I was reading a lot on SO and other sources but could not figure out what is wrong. Btw. as a result of compilation some other classes were created: file$1.class file$name1.class file$name2.class (where name1 and name2 are names of private classes within file.java) My questions are: What is (the most) probably source of my error / what am I doing wrong? What is the purpose of file$1.class? What is the minimum I should specify in -cp? May encoding play any role? Do every java class have to reside in a package? (rather not directly related to my issue) Do order of paths specified in -cp play any role in runtime?

  • Help with my PHP template class

    - by blerh
    I want to separate the output of HTML from my program code in my projects, so I wrote a very simple database class. <?php class Template { private $template; function load($filePath) { if(!$this->template = file_get_contents($filePath)) $this->error('Error: Failed to open <strong>' . $filePath . '</strong>'); } function replace($var, $content) { $this->template = str_replace("{$var}", $content, $this->template); } function display() { echo $this->template; } function error($errorMessage) { die('die() by template class: <strong>' . $errorMessage . '</strong>'); } } ?> The thing I need help with is the display() method. Say for example I use this code: $tplObj = new Template(); $tplObj->load('index.php'); $tplObj->replace('{TITLE}', 'Homepage'); $tplObj->display(); And the index.php file is this: <html> <head> <title>{TITLE}</title> </head> <body> <h1>{TITLE}</h1> <?php if($something) { echo '$something is true'; } else { echo '$something is false'; } ?> </body> </html> I'm just wondering if the PHP code in there would be run? Or would it just be sent to the browser as plaintext? I was using eval() in my template class but I hate that function :P Thanks.

  • Why delete-orphan needs "cascade all" to run in JPA/Hibernate ?

    - by Jerome C.
    Hello, I try to map a one-to-many relation with cascade "remove" (jpa) and "delete-orphan", because I don't want children to be saved or persist when the parent is saved or persist (security reasons due to client to server (GWT, Gilead)) But this configuration doesn't work. When I try with cascade "all", it runs. Why the delete-orphan option needs a cascade "all" to run ? here is the code (without id or other fields for simplicity, the class Thread defines a simple many-to-one property without cascade): when using the removeThread function in a transactional function, it does not run but if I edit cascade.Remove into cascade.All, it runs. @Entity public class Forum { private List<ForumThread> threads; /** * @return the topics */ @OneToMany(mappedBy = "parent", cascade = CascadeType.REMOVE, fetch = FetchType.LAZY) @Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN) public List<ForumThread> getThreads() { return threads; } /** * @param topics the topics to set */ public void setThreads(List<ForumThread> threads) { this.threads = threads; } public void addThread(ForumThread thread) { getThreads().add(thread); thread.setParent(this); } public void removeThread(ForumThread thread) { getThreads().remove(thread); } } thanks.

  • The following code to check if a file exists on a server does not work

    - by xplorer2k
    Hi Everyone, I found the following code to check if a file exists on a server, but is not working for me. It tells me that "test1.tx" does not exist even though the file exists and its size is 498 bytes. If I try with Ftp.ListDirectory it tells me that the file does not exist. If I try with Ftp.GetFileSize it does not provide any results and the debugger's immediate gives me the following message: A first chance exception of type 'System.Net.WebException' occurred in System.dll. Using "request.UseBinary = true" does not make any difference. I have posted this same question at this link: http://social.msdn.microsoft.com/Forums/en-US/ncl/thread/89e05cf3-189f-48b7-ba28-f93b1a9d44ae Could someone help me how to fix it? private void button1_Click(object sender, EventArgs e) { string ftpServerIP = txtIPaddress.Text.Trim(); string ftpUserID = txtUsername.Text.Trim(); string ftpPassword = txtPassword.Text.Trim(); try { FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + ftpServerIP + "//tmp/test1.txt"); request.Method = WebRequestMethods.Ftp.ListDirectory; //request.Method = WebRequestMethods.Ftp.GetFileSize; request.Credentials = new NetworkCredential(ftpUserID, ftpPassword); //request.UseBinary = true; using (FtpWebResponse response = (FtpWebResponse)request.GetResponse()) { // Okay. textBox1.AppendText(Environment.NewLine); textBox1.AppendText("File exist"); } } catch (WebException ex) { if (ex.Response != null) { FtpWebResponse response = (FtpWebResponse)ex.Response; if (response.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable) { // Directory not found. textBox1.AppendText(Environment.NewLine); textBox1.AppendText("File does not exist"); } } } } Thanks very much, xplorer2k

  • Simple Java Applet not loading in FireFox / Safari on MacOS

    - by Sleepless
    Hello all, I'm probably missing something very basic here. I'm trying to get my first applet to run inside a local HTML page in Firefox 3.6 on Mac OS 10.5.8. Here's the applet's code: package SimpleApplet; import java.applet.Applet; import java.awt.*; public class MyApplet extends Applet { private static final long serialVersionUID = 1L; public void init() { } public void stop() { } public void paint(Graphics g) { g.drawString("Tweedle-Dee!",20,40); } } Here's the HTML page: <html> <body> Here's the applet: <br/> <applet code="MyApplet.class" width="300" height="150"> </applet> </body> </html> Both files (.class and .html) are in the same folder on my local machine. Now when I load the .html file into Firefox, a rectangle with a red X gets displayed. The applet works when started from Eclipse (using JRE 1.5 BTW). Also, it's not a general problem with my browser, as several pages with applets (e.g. http://java.sun.com/applets/jdk/1.4/demo/applets/Blink/example1.html) work. This is also difficult to troubleshoot because there is no output at all on the Java console... Any suggestions are appreciated!

  • gridview commandargument on buttonfield pagination used

    - by ClareBear
    Hello all, I am using c#.net I have a gridview which needs to contain a 'Use' button (appointmentId set as the commandargument).

  • Generic C# Class: Set "Generic" Property

    - by BlaM
    I'm quite new to C#, so I might have a problem that C# has a simple solution for. I have a generic class with a property of "generic" type. I want to have a function to set that property, but I need to convert it to do so. public class BIWebServiceResult<T> { public T Data; public delegate StatusCode StringToStatusCode(string Input); public void SetData(string Input, StringToStatusCode StringToError) { if (StringToError(Input) == 0) { if (Data is string[]) { Data = new string[1]; Data[0] = Input; } else if (Data is string) { Data = Input; } else if (Data is bool) { Data = DetectBool(Input); } } } private bool DetectBool(string Compare) { return Compare == "true"; } } The problem with that approach is, that it does not work :) (No that's not all code, just a snippet to show what my problem is) It doesn't even compile, because "Data = new string[]" can't work if Data is - for example - boolean. How do I implement a function that behaves differently depending on the type of my generic property?

  • Is this a clean way to manage AsyncResults with Generic Methods?

    - by Michael Stum
    I've contributed Async Support to a Project I'm using, but I made a bug which I'm trying to fix. Basically I have this construct: private readonly Dictionary<WaitHandle, object> genericCallbacks = new Dictionary<WaitHandle, object>(); public IAsyncResult BeginExecute<T>(RestRequest request, AsyncCallback callback, object state) where T : new() { var genericCallback = new RequestExecuteCaller<T>(this.Execute<T>); var asyncResult = genericCallback.BeginInvoke(request, callback, state); genericCallbacks[asyncResult.AsyncWaitHandle] = genericCallback; return asyncResult; } public RestResponse<T> EndExecute<T>(IAsyncResult asyncResult) where T : new() { var cb = genericCallbacks[asyncResult.AsyncWaitHandle] as RequestExecuteCaller<T>; genericCallbacks.Remove(asyncResult.AsyncWaitHandle); return cb.EndInvoke(asyncResult); } So I have a generic BeginExecute/EndExecute method pair. As I need to store the delegate that is called on EndExecute somewhere I created a dictionary. I'm unsure about using WaitHandles as keys though, but that seems to be the only safe choice. Does this approach make sense? Are WaitHandles unique or could I have two equal ones? Or should I instead use the State (and wrap any user provided state into my own State value)? Just to add, the class itself is non-generic, only the Begin/EndExecute methods are generic.

  • How do I unit test controllers for an asp.net mvc site that uses StructureMap and NHibernate?

    - by Jim Geurts
    I have an asp.net mvc2 application that is using StructureMap 2.6 and NHibernate 3.x. I would like to add unit tests to the application but am sort of at a loss for how to accomplish it. Say I have a basic controller called Posts that has an action called Index. The controller looks something like: public class PostsController : Controller { private readonly IPostService _postService; public PostsController(IPostService postService) { _postService = postService; } public ActionResult Index() { return View(_postService.QueryOver<Post>().Future()); } } If I wanted to create an nunit test that would verify that the index action is returning all of the posts, how do I go about that? If mocking is recommended, do you just assume that interaction with the database will work? Sorry for asking such a broad question, but my web searches haven't turned up anything decent for how to unit test asp.net mvc actions that use StructureMap (or any other IOC) and NHibernate. btw, if you don't like that I return a QueryOver object from my post service, pretend it is an IQueryable object. I'm using it essentially in the same way.

  • "É" not getting converted to two bytes correctly.

    - by ChrisF
    Further to this question I've got a supplementary problem. I've found a track with an "É" in the title. My code: var playList = new StreamWriter(playlist, false, Encoding.UTF8); - private static void WriteUTF8(StreamWriter playList, string output) { byte[] byteArray = Encoding.UTF8.GetBytes(output); foreach (byte b in byteArray) { playList.Write(Convert.ToChar(b)); } } converts this to the following bytes: 195 137 which is being output as à followed by a square (which is an character that can't be printed in the current font). I've exported the same file to a playlist in Media Monkey at it writes the "É" as "É" - which I'm assuming is correct (as KennyTM pointed out). My question is, how do I get the "‰" symbol output? Do I need to select a different font and if so which one? UPDATE People seem to be missing the point. I can get the "É" written to the file using playList.WriteLine("É"); that's not the problem. The problem is that Media Monkey requires the file to be in the following format: #EXTINFUTF8:140,Yann Tiersen - Comptine D'Un Autre Été: L'Après Midi #EXTINF:140,Yann Tiersen - Comptine D'Un Autre Été: L'Après Midi #UTF8:04-Comptine D'Un Autre Été- L'Après Midi.mp3 04-Comptine D'Un Autre Été- L'Après Midi.mp3 Where all the "high-ascii" (for want of a better term) are written out as a pair of characters.

  • CheckBox won't toggle in Android ListView with focusable="false"

    - by user3563124
    I'm creating a ListView with a custom Adapter for displaying my entries. Each row contains a checkbox, and my adapter contains the following code: CheckBox cb = (CheckBox) v.findViewById(R.id.item_sold); cb.setChecked(p.isSold); setupCheckboxListener(cb, v, position); ... private void setupCheckboxListener(CheckBox check, final View v, final int position) { check.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { CheckBox cb = (CheckBox) v; if (cb.isChecked()) { System.out.println("Should become false!"); cb.setChecked(false); } else { System.out.println("Should become true!"); cb.setChecked(true); } } }); My row XML file includes the following: <CheckBox android:id="@+id/item_sold" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="0.10" android:layout_gravity="center" android:gravity="center" android:focusable="false" android:clickable="false"/> But anytime I press one of the checkboxes, check.isChecked() returns true, even if the box is unchecked. I even checked to make sure that the checkboxes were distinct and weren't picking up just the last value/etc. Setting up the listeners inline instead of in a method doesn't seem to help, either. It's literally just the isChecked() condition that isn't working appropriately - it seems to always give me the inverse value. Setting an onClick on the row is not acceptable in this case because I need to allow row selection for something else. What could be causing this issue?

  • Constructor is being invoked twice

    - by Knowing me knowing you
    In code: LINT a = "12"; LINT b = 3; a = "3";//WHY THIS LINE INVOKES CTOR? std::string t = "1"; //LINT a = t;//Err NO SUITABLE CONV FROM STRING TO LINT.

  • Custom QAbstractGraphicsShapeItem very slow in Qt Jambi

    - by Mene
    I try to implement an own QAbstractGraphicsShapeItem in Qt Jambi (4.5) but as soon as I implement a custom class (rather than use e.g. QGraphicsEllipseItem) the rendering speed drops by about on order of magnitude. If looked in the original Code of QGraphicsEllipseItem and it seems to do basicly the same. class Circle extends QAbstractGraphicsShapeItem { final private QRectF rect = new QRectF(); public final void setRect(double x, double y, double w, double h) { QRectF newRect = new QRectF(x, y, w, h); if (!newRect.equals(rect)) { prepareGeometryChange(); this.rect.setX(x); this.rect.setY(y); this.rect.setWidth(w); this.rect.setHeight(h); this.update(rect); } } @Override public final QRectF boundingRect() { return rect; } QPainterPath shape; @Override public final QPainterPath shape() { if (shape == null) { QPainterPath path = new QPainterPath(); path.addEllipse(rect); QPainterPathStroker stroker = new QPainterPathStroker(); QPen pen = this.pen(); stroker.setCapStyle(pen.capStyle()); stroker.setWidth(pen.widthF()); shape = stroker.createStroke(path); } return shape; } @Override public final void paint(QPainter painter, QStyleOptionGraphicsItem option, QWidget widget) { painter.setPen(this.pen()); painter.setBrush(this.brush()); painter.drawEllipse(this.rect); } } I need to render a lot of objects and they are mostly moving, so speed is essential. Anyone knows how to speed this up? I underestand that Java might be slower then the nativ code in the library. But the code in the paint method seems not to be the problem, since commenting it out doesn't change the speed notably.

  • Executing javascript script after ajax-loaded a page - doesn't work

    - by Deukalion
    I'm trying to get a page with AJAX, but when I get that page and it includes Javascript code - it doesn't execute it. Why? Simple code in my ajax page: <script type="text/javascript"> alert("Hello"); </script> ...and it doesn't execute it. I'm trying to use Google Maps API and add markers with AJAX, so whenever I add one I execute a AJAX page that gets the new marker, stores it in a database and should add the marker "dynamically" to the map. But since I can't execute a single javascript function this way, what do I do? Is my functions that I've defined on the page beforehand protected or private? ** UPDATED WITH AJAX FUNCTION ** function ajaxExecute(id, link, query) { if (query != null) { query = query.replace("amp;", ""); } if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else { // code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { if (id != null) { document.getElementById(id).innerHTML=xmlhttp.responseText; } } } if (query == null) { xmlhttp.open("GET",link,true); } else { if (query.substr(0, 1) != "?") { xmlhttp.open("GET",link+"?"+query,true); } else { xmlhttp.open("GET",link+query,true); } } xmlhttp.send(); }

  • Best practices for managing updating a database with a complex set of changes

    - by Sarge
    I am writing an application where I have some publicly available information in a database which I want the users to be able to edit. The information is not textual like a wiki but is similar in concept because the edits bring the public information increasingly closer to the truth. The changes will affect multiple tables and the update needs to be automatically checked before affecting the public tables. I'm working on the design and I'm wondering if there are any best practices that might help with some particular issues. I want to provide undo capability. I want to show the user the combined result of all their changes. When the user says they're done, I need to check the underlying public data to make sure it hasn't been changed by somebody else. My current plan is to have the user work in a set of tables setup to be a private working area. Once they're ready they can kick off a process to check everything and update the public tables. Undo can be recorded using Command pattern saving to a table. Are there any techniques I might have missed or useful papers or patterns? Thanks in advance!

A workaround is to open the java control center and enable logging. This is a concern since by default "Enable Logging" is unchecked. If I select "Enable Logging", the application starts fine.

  • How to cache an HTTP POST response?

    - by KARASZI István
    I would like to create a cacheable HTTP response for a POST request. My actual implementation responses the following for the POST request: HTTP/1.1 201 Created Expires: Sat, 03 Oct 2020 15:33:00 GMT Cache-Control: private,max-age=315360000,no-transform Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Content-Length: 9 ETag: 2120507660800737950 Last-Modified: Wed, 06 Oct 2010 15:33:00 GMT ......... But it looks like that the browsers (Safari, Firefox tested) are not cacheing the response. In the HTTP RFC the corresponding part says: Responses to this method are not cacheable, unless the response includes appropriate Cache-Control or Expires header fields. However, the 303 (See Other) response can be used to direct the user agent to retrieve a cacheable resource. So I think it should be cached. I know I could set a session variable and set a cookie and do a 303 redirect, but I want to cache the response of the POST request. Is there any way to do this? P.S.: I've started with a simple 200 OK, so it does not work. Thanks,

    Inside my controller's action I have the following code: public ActionResult GridAction(string id) { if (String.IsNullOrEmpty(id)) { // add errors to the errors collection and then return the view saying that you cannot select the dropdownlist value with the "Please Select" option } return View(); UPDATE: if (String.IsNullOrEmpty(id)) { // add error ModelState.AddModelError("GridActionDropDownList", "Please select an option"); return RedirectToAction("Orders"); } } UPDATE 2: Here is my updated code: @Html.DropDownListFor(x => x.SelectedGridAction, Model.GridActions,"Please Select") @Html.ValidationMessageFor(x => x.SelectedGridAction) The Model looks like the following: public class MyInvoicesViewModel { private List<SelectListItem> _gridActions; public int CurrentGridAction { get; set; } [Required(ErrorMessage = "Please select an option")] public string SelectedGridAction { get; set; } public List<SelectListItem> GridActions { get { _gridActions = new List<SelectListItem>(); _gridActions.Add(new SelectListItem() { Text = "Export to Excel", Value = "1"}); return _gridActions; } } } And here is my controller action: public ActionResult GridAction(string id) { if (String.IsNullOrEmpty(id)) { // add error ModelState.AddModelError("SelectedGridAction", "Please select an option"); return RedirectToAction("Orders"); } return View(); } Nothing happens! I am totally lost on this one! UPDATE 3: I am now using the following code but still the validation is not firing: public ActionResult GridAction(string id) { var myViewModel= new MyViewModel(); myViewModel.SelectedGridAction = id; // id is passed as null if (!ModelState.IsValid) { return View("Orders"); }

  • VBA: How go I get the total width from all controls in an MS-Access form?

    - by Stefan Åstrand
    Hi, This is probably very basic stuff, but please bear in mind I am completely new to these things. I am working on a procedure for my Access datasheet forms that will: Adjust the width of each column to fit content Sum the total width of all columns and subtract it from the size of the window's width Adjust the width of one of the columns to fit the remaining space This is the code that adjusts the width of each column to fit content (which works fine): Dim Ctrl As Control Dim Path As String Dim ClmWidth As Integer 'Adjust column width to fit content For Each Ctrl In Me.Controls If TypeOf Ctrl Is TextBox Then Path = Ctrl.Name Me(Path).ColumnWidth = -2 End If Next Ctrl How should I write the code so I get the total width of all columns? Thanks a lot! Stefan Solution This is the code that makes an Access datasheet go from this: To this: Sub AdjustColumnWidth(frm As Form, clm As String) On Error GoTo HandleError Dim intWindowWidth As Integer ' Window width property Dim ctrl As Control ' Control Dim intCtrlWidth As Integer ' Control width property Dim intCtrlSum As Integer ' Control width property sum Dim intCtrlAdj As Integer ' Control width property remaining after substracted intCtrSum 'Adjust column width to standard width For Each ctrl In frm.Controls If TypeOf ctrl Is TextBox Or TypeOf ctrl Is CheckBox Or TypeOf ctrl Is ComboBox Then Path = ctrl.Name frm(Path).ColumnWidth = 1500 End If Next ctrl 'Get total column width For Each ctrl In frm.Controls If TypeOf ctrl Is TextBox Or TypeOf ctrl Is CheckBox Or TypeOf ctrl Is ComboBox Then Path = ctrl.Name intCtrlWidth = frm(Path).ColumnWidth If Path <> clm Then intCtrlSum = intCtrlSum + intCtrlWidth End If End If Next ctrl 'Adjust column to fit window intWindowWidth = frm.WindowWidth - 270 intCtrlAdj = intWindowWidth - intCtrlSum frm.Width = intWindowWidth frm(clm).ColumnWidth = intCtrlAdj Debug.Print "Totalt (Ctrl): " & intCtrlSum Debug.Print "Totalt (Window): " & intWindowWidth Debug.Print "Totalt (Remaining): " & intCtrlAdj Debug.Print "clm : " & clm HandleError: GeneralErrorHandler Err.Number, Err.Description Exit Sub End Sub Code to call procedure: Private Sub Form_Load() Call AdjustColumnWidth(Me, "txtDescription") End Sub

  • Binder and variadic template ends up in a segmentation fault

    - by phlipsy
    I wrote the following program #include <iostream> template<typename C, typename Res, typename... Args> class bind_class_t { private: Res (C::*f)(Args...); C *c; public: bind_class_t(Res (C::*f)(Args...), C* c) : f(f), c(c) { } Res operator() (Args... args) { return (c->*f)(args...); } }; template<typename C, typename Res, typename... Args> bind_class_t<C, Res, Args...> bind_class(Res (C::*f)(Args...), C* c) { return bind_class<C, Res, Args...>(f, c); } class test { public: int add(int x, int y) { return x + y; } }; int main() { test t; // bind_class_t<test, int, int, int> b(&test::add, &t); bind_class_t<test, int, int, int> b = bind_class(&test::add, &t); std::cout << b(1, 2) << std::endl; return 0; } compiled it with gcc 4.3.3 and got a segmentation fault. After spending some time with gdb and this program it seems to me that the addresses of the function and the class are mixed up and a call of the data address of the class isn't allowed. Moreover if I use the commented line instead everything works fine. Can anyone else reproduce this behavior and/or explain me what's going wrong here?

  • Can the Singleton be replaced by Factory?

    - by lostiniceland
    Hello Everyone There are already quite some posts about the Singleton-Pattern around, but I would like to start another one on this topic since I would like to know if the Factory-Pattern would be the right approach to remove this "anti-pattern". In the past I used the singleton quite a lot, also did my fellow collegues since it is so easy to use. For example, the Eclipse IDE or better its workbench-model makes heavy usage of singletons as well. It was due to some posts about E4 (the next big Eclipse version) that made me start to rethink the singleton. The bottom line was that due to this singletons the dependecies in Eclipse 3.x are tightly coupled. Lets assume I want to get rid of all singletons completely and instead use factories. My thoughts were as follows: hide complexity less coupling I have control over how many instances are created (just store the reference I a private field of the factory) mock the factory for testing (with Dependency Injection) when it is behind an interface In some cases the factories can make more than one singleton obsolete (depending on business logic/component composition) Does this make sense? If not, please give good reasons for why you think so. An alternative solution is also appreciated. Thanks Marc

  • SIGABRT Issues with UIApplication_TVOut and MPVideoView - is there another way??

    - by user365920
    Hi there, I am due to do a demo in a week of an app which i have been working on for a company - until now, i have been using code taken from this useful tutorial here The problem is that this no longer seems to be working - causing a SIGABRT inside of the following (see initWithVideoView): - (void) startTVOut; { // you need to have a main window already open when you call start if (!tvoutWindow) { deviceWindow = [self keyWindow]; MPVideoView *vidView = [[MPVideoView alloc] initWithFrame: CGRectZero]; **tvoutWindow = [[MPTVOutWindow alloc] initWithVideoView:vidView];** [tvoutWindow makeKeyAndVisible]; tvoutWindow.userInteractionEnabled = NO; mirrorView = [[UIImageView alloc] initWithFrame: [[UIScreen mainScreen] bounds]]; [self reformatTVOutOrientation]; mirrorView.center = vidView.center; [vidView addSubview: mirrorView]; [deviceWindow makeKeyAndVisible]; [NSThread detachNewThreadSelector:@selector(updateLoop) toTarget:self withObject:nil]; } } Can anyone help at all??? This was all working fine, but seems to have stopped working recently - none of my code has changed, so assuming Apple have removed that API (yes, i know it was a private API in the first place, so im not moaning!) Just need to know if there is an alternative way of displaying the contents of my iPhone screen in my app... Many thanks in advance!
