  • Cannot change font size /type in plots

    - by Sameet Nabar
    I recently had to re-install my operating system (Ubuntu). The only thing I did differently is that I installed Matlab on a separate partition, not the main Ubuntu partition. After re-installing, the fonts in my plots are no longer configurable. For example, if I ask the title font to be bold, it doesn't happen. I ran the sample code below on my computer and then on my colleague's computer and the 2 results are attached. This cannot be a problem with the code; rather in the settings of Matlab. Could somebody please tell me what settings I need to change? Thanks in advance for your help. Regards, Sameet. x1=-pi:.1:pi; x2=-pi:pi/10:pi; y1=sin(x1); y2=tan(sin(x2)) - sin(tan(x2)); [AX,H1,H2]=plotyy(x1,y1,x2,y2); xlabel ('Time (hh:mm)'); ylabel (AX(1), 'Plot1'); ylabel (AX(2), 'Plot2'); axes(AX(2)) set(H1,'linestyle','none','marker','.'); set(H2,'linestyle','none','marker','.'); title('Plot Title','FontWeight','bold'); set(gcf, 'Visible', 'off'); [legh, objh] = legend([H1 H2],'Plot1', 'Plot2','location','Best'); set(legend,'FontSize',8); print -dpng Trial.png; Bad image: http://imageshack.us/photo/my-images/708/trial1u.png/ Good image: http://imageshack.us/photo/my-images/87/trial2.png/

  • How to extract data from F# list

    - by David White
    Following up my previous question, I'm slowly getting the hang of FParsec (though I do find it particularly hard to grok). My next newbie F# question is, how do I extract data from the list the parser creates? For example, I loaded the sample code from the previous question into a module called Parser.fs, and added a very simple unit test in a separate module (with the appropriate references). I'm using XUnit: open Xunit [<Fact>] let Parse_1_ShouldReturnListContaining1 () = let interim = Parser.parse("1") Assert.False(List.isEmpty(interim)) let head = interim.Head // I realise that I have only one item in the list this time Assert.Equal("1", ???) Interactively, when I execute parse "1" the response is: val it : Element list = [Number "1"] and by tweaking the list of valid operators, I can run parse "1+1" to get: val it : Element list = [Number "1"; Operator "+"; Number "1"] What do I need to put in place of my ??? in the snippet above? And how do I check that it is a Number, rather than an Operator, etc.?

  • How can I compile .NET 3.5 C# code on a system without Visual Studio?

    - by JimEvans
    I have some C# code that uses some constructs specific to .NET 3.5. When you install the .NET Framework distribution, you get the C# compiler installed with it (csc.exe). Even if I specify the csc.exe in C:\Windows\Microsoft.NET\Framework\v3.5, I cannot compile the code on a computer with only the .NET Framework installed, but not Visual Studio. I am able to compile code that uses v2.0 constructs without difficulty. How can I accomplish this? Here is a sample that demonstrates my problem: using System; class Program { public static void Main() { // The MacOSX value to the PlatformID enum was added after // .NET v2.0 if (Environment.OSVersion.Platform == PlatformID.MacOSX) { Console.WriteLine("Found mac"); } Console.WriteLine("Simple program"); } } When compiling this code using csc.exe, I receive the following error: test.cs(9, 58): error CS0117: 'System.PlatformID' does not contain a definition for 'MacOSX' When executing csc.exe /? I receive the banner: Microsoft (R) Visual C# 2008 Compiler version 3.5.21022.8 for Microsoft (R) .NET Framework version 3.5 Copyright (C) Microsoft Corporation. All rights reserved.

  • How to use libavformat for a separate encoder?

    - by Brendon Tsai
    I've build a encoder based on the sample of QUALCOMM, which captures the video and compresses it into h264 file. I am using Android 4.2.2. Now I want to add a mp4 muxer into this encoder(actually, just video will be fine, I don't need audio). I want to use FFMpeg. But after I read the example, I found out that the muxer was using the encoder of FFMpeg. I don't know how to use the muxer part for another encoder. I've read this post, but I don't understand how the code provide video stream to the muxer. I think that mainly because I don't understand these code: AVCodecContext * strmCodec = oFmtCtx->streams[0]->codec; // Fill the required properties for codec context. // *from the documentation: // *The user sets codec information, the muxer writes it to the output. // *Mandatory fields as specified in AVCodecContext // *documentation must be set even if this AVCodecContext is // *not actually used for encoding. my_tune_codec(strmCodec); Can anyone give me a hint? Thank you!

  • Significance in R

    - by Gemsie
    Ok, this is quite hard to explain, but I'm at a complete loss what to do. I'm a relative newcomer to R and although I can completely admire how powerful it is, I'm not too good at actually using it.... Basically, I have some very contrived data that I need to analyse (it wasn't me who chose this, I can assure you!). I have the right and left hand lengths of lots of people, as well as some numeric data that shows their sociability. Now I would like to know if people who have significantly different lengths of hand are more or less sociable than those who have the same (leading into the research that 'symmetrical' people are more sociable and intelligent, etc. I have got as far as loading the data into R, then I have no idea where to go from there. How on Earth do I start to separate those who are close to symmetrical to those who aren't to then start to do the analysis? Ok, using Sasha's great advice, I did the cor.test and got the following: Pearson's product-moment correlation data: measurements$l.hand - measurements$r.hand and measurements$sociable t = 0.2148, df = 150, p-value = 0.8302 alternative hypothesis: true correlation is not equal to 0 95 percent confidence interval: -0.1420623 0.1762437 sample estimates: cor 0.01753501 I have never used this test before, so am unsure how to intepret it...you wouldn't think I was on my fourth Scientific degree would you?! :(

  • Hiding a Bar button item in the view

    - by devb0yax
    How can you able to hide the (done) bar button item in a view? Basically, I have a view controller added with navigation bar (in IB) then, I also added a bar button item into the nav bar. I just want initially the (done) bar button item is hidden.. when input is in the text view the (done) button is already visible. Any idea on this implementation on a view controller? Here's my sample code: @interface MyTextViewViewController : UIViewController <UITextViewDelegate> { UITextView *m_textView; UIBarButtonItem *doneBarButtonItem; } @property(nonatomic,retain) IBOutlet UITextView *m_textView; @property(nonatomic,retain) IBOutlet UIBarButtonItem *doneBarButtonItem; - (IBAction)saveAction:(id)sender; .m file: - (void)viewDidLoad { [super viewDidLoad]; doneBarButtonItem.hidden = YES; --> compile error!!! } - (void)textViewDidBeginEditing:(UITextView *)textView { doneBarButtonItem.hidden = NO; --> compile error!!! } - (IBAction)saveAction:(id)sender { doneBarButtonItem.hidden = YES; --> compile error!!! ... }

  • Within an aray of objects can one create a new instance of an object at an index?

    - by David
    Here's the sample code: class TestAO { int[] x; public TestAO () { this.x = new int[5] ; for (int i = 0; i<x.length; i++) x[i] = i; } public static void main (String[]arg) { TestAO a = new TestAO (); System.out.println (a) ; TestAO c = new TestAO () ; c.x[3] = 35 ; TestAO[] Z = new TestAO[3] ; Z[0] = a ; Z[1] = (TestAO b = new TestAO()) ; Z[2] = c ; } } When i try to compile this i get an error message at the line Z[1] which reads as follows: TestAO.java:22: ')' expected Z[1] = (TestAO b = new TestAO()) ; ^ What i'm trying to do here is create an instance of the object TestAO that i want to be in that index within the assignment of the value at that index instead of creating the instance of the object outside of the array like i did with a. Is this legal and i'm just making some syntax error that i can't see (thus causing the error message) or can what i'm trying to do just not be done?

  • When does the call() method get called in a Java Executor using Callable objects?

  • C when to allocate and free memory - before function call, after function call...etc

    - by Keith P
    I am working with my first straight C project, and it has been a while since I worked on C++ for that matter. So the whole memory management is a bit fuzzy. I have a function that I created that will validate some input. In the simple sample below, it just ignores spaces: int validate_input(const char *input_line, char* out_value){ int ret_val = 0; /*false*/ int length = strlen(input_line); cout << "length = " << length << "\n"; out_value =(char*) malloc(sizeof(char) * length + 1); if (0 != length){ int number_found = 0; for (int x = 0; x < length; x++){ if (input_line[x] != ' '){ /*ignore space*/ /*get the character*/ out_value[number_found] = input_line[x]; number_found++; /*increment counter*/ } } out_value[number_found + 1] = '\0'; ret_val = 1; } return ret_val; } Instead of allocating memory inside the function for out_value, should I do it before I call the function and always expect the caller to allocate memory before passing into the function? As a rule of thumb, should any memory allocated inside of a function be always freed before the function returns?

  • XAML get new width and height for Canvas

    - by Jack Navarro
    I have searched through many times but have not seen this before. Probably really simple question but can't wrap my head around it. Wrote a VSTO add-in for Excel that draws a Grid dynamically. Then launches a new window and replaces the contents of the Canvas with the generated Grid. The problem is with printing. When I call the print procedure the canvas.height and canvas.width returned is the old value prior to replacing it with the grid. Sample: string="<Grid Name=\"CanvasGrid\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\">..Lots of stuff..</Grid>"; // Launch new window and replace the Canvas element WpfUserControl newWindow = new WpfUserControl(); newWindow.Show(); //To test MessageBox.Show(myCanvas.ActualWidth.ToString()); //return 894 Grid testGrid = myCanvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 StringReader stringReader = new StringReader(LssAllcChrt); XmlReader xmlReader = XmlReader.Create(stringReader); Canvas myCanvas = newWindow.FindName("GrphCnvs") as Canvas; myCanvas.Children.Clear(); myCanvas.Children.Add((UIElement)XamlReader.Load(xmlReader)); //To test MessageBox.Show(myCanvas.ActualWidth.ToString()); //return 894 but should be much larger the Grid spans all three of my screens Grid testGrid = myCanvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 but should be much larger the Grid spans all three of my screens //Run code from WpfUserControl.cs after it loads from button click Grid testGrid = canvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 but should be much larger the Grid spans all three of my screens So basically I have no way of telling what my new width and height are.

  • File streaming in PHP - How to replicate this C#.net code in PHP?

    - by openid_kenja
    I'm writing an interface to a web service where we need to upload configuration files. The documentation only provides a sample in C#.net which I am not familiar with. I'm trying to implement this in PHP. Can someone familiar with both languages point me in the right direction? I can figure out all the basics, but I'm trying to figure out suitable PHP replacements for the FileStream, ReadBytes, and UploadDataFile functions. I believe that the RecService object contains the URL for the web service. Thanks for your help! private void UploadFiles() { clientAlias = “<yourClientAlias>”; string filePath = “<pathToYourDataFiles>”; string[] fileList = {"Config.txt", "ProductDetails.txt", "BrandNames.txt", "CategoryNames.txt", "ProductsSoldOut.txt", "Sales.txt"}; RecommendClient RecService = new RecommendClient(); for (int i = 0; i < fileList.Length; i++) { bool lastFile = (i == fileList.Length - 1); //start generator after last file try { string fileName = filePath + fileList[i]; if (!File.Exists(fileName)) continue; // file not found } // set up a file stream and binary reader for the selected file and convert to byte array FileStream fStream = new FileStream(fileName, FileMode.Open, FileAccess.Read); BinaryReader br = new BinaryReader(fStream); byte[] data = br.ReadBytes((int)numBytes); br.Close(); // pass byte array to the web service string result = RecService.UploadDataFile(clientAlias, fileList[i], data, lastFile); fStream.Close(); fStream.Dispose(); } catch (Exception ex) { // log an error message } } }

  • asp.net master page/content page interaction with style sheet

    - by Matt
    Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008 CSS sample: body { height:1200px; width:920px; border-style:solid; border-color:blue; padding:10px 10px 10px 10px; } #toptext1 { position:relative; top:-225px; right:-500px; font-size:22px; font-weight:bold; } From the master page: <body> <form id="form1" runat="server"> <asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server" AlternateText="CookNook" Width="449px"></asp:image> <p> <asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label> </p> From the content page: <%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> <link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" /> </asp:Content> When I was doing this without a master page it worked so where am I going wrong with the attributes?

  • CodeIgniter and SimpleTest -- How to make my first test?

    - by Smandoli
    I'm used to web development using LAMP, PHP5, MySQL plus NetBeans with Xdebug. Now I want to improve my development, by learning how to use (A) proper testing and (B) a framework. So I have set up CodeIgniter, SimpleTest and the easy Xdebug add-in for Firefox. This is great fun because maroonbytes provided me with clear instructions and a configured setup ready for download. I am standing on the shoulders of giants, and very grateful. I've used SimpleTest a bit in the past. Here is a the kind of thing I wrote: <?php require_once('../simpletest/unit_tester.php'); require_once('../simpletest/reporter.php'); class TestOfMysqlTransaction extends UnitTestCase { function testDB_ViewTable() { $this->assertEqual(1,1); // a pseudo-test } } $test = new TestOfMysqlTransaction(); $test->run(new HtmlReporter()) ?> So I hope I know what a test looks like. What I can't figure out is where and how to put a test in my new setup. I don't see any sample tests in the maroonbytes package, and Google so far has led me to posts that assume unit testing is already functionally available. What do I do?

  • Why initialize an object to empty

    - by ProgEnthu
    I am learning windows programming with the help of MSDN.Why would somebody initialize an object like the following? WNDCLASS wc = { }; Will this zero all the memory of the object? Whole source code is following: #ifndef UNICODE #define UNICODE #endif #include <windows.h> LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam); int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE, PWSTR pCmdLine, int nCmdShow) { // Register the window class. const wchar_t CLASS_NAME[] = L"Sample Window Class"; WNDCLASS wc = { }; wc.lpfnWndProc = WindowProc; wc.hInstance = hInstance; wc.lpszClassName = CLASS_NAME; RegisterClass(&wc); // Create the window.

  • iPad3 HD Black Screen in Portrait Orientation

    - by Jason Brooks
    I'm currently updating my game using XCode 4.3.1 and an iPad3. WHen iPAD HD mode is selected, I get a black screen when I change the scene from the AppDelegate. I'm using COCOS2d v1.0.1 My Game is portrait only mode, and I think I've tracked the problem down. If you create a new project with the default HelloWorld Layer, it works on the iPad3 and it's simulator in HD. However if you change the following code :- -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { ... #elif GAME_AUTOROTATION == kGameAutorotationUIViewController // // EAGLView will be rotated by the UIViewController // // Sample: Autorotate only in landscpe mode // // return YES for the supported orientations //return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) ); return ( UIInterfaceOrientationIsPortrait ( interfaceOrientation ) ); //return NO; ... } In RootViewController.m You see a black screen for the iPad3 real device and simulator. It works as expected on all devices, iPhone/iPod Touch, and iPad 1 and 2. If I change the statement back to return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) ); I get the Hello World rendered to the screen, but it is in landscape only on iPad3. Has anyone else encountered this and have any suggestions for a fix? The project is quite large to upgrade to the latest V1 Beta code.

  • Stop Observing Events with JS Prototype not working with .bind(this)

    - by PeterBelm
    I'm working on a Javascript class based on the Prototype library. This class needs to observe an event to perform a drag operation (the current drag-drop controls aren't right for this situation), but I'm having problems making it stop observing the events. Here's a sample that causes this problem: var TestClass = Class.create({ initialize: function(element) { this.element = element; Event.observe(element, 'mousedown', function() { Event.observe(window, 'mousemove', this.updateDrag.bind(this)); Event.observe(window, 'mouseup', this.stopDrag.bind(this)); }); }, updateDrag: function(event) { var x = Event.pointerX(event); var y = Event.pointerY(event); this.element.style.top = y + 'px'; this.element.style.left = x + 'px'; }, stopDrag: function(event) { console.log("stopping drag"); Event.stopObserving(window, 'mousemove', this.updateDrag.bind(this)); Event.stopObserving(window, 'mouseup', this.stopDrag.bind(this)); } }); Without .bind(this) then this.element is undefined, but with it the events don't stop being observed (the console output does occur though).

  • asp.net Can I force every page to inherit from a base page? Also should some of this logic be in my master page?

    - by Bex
    Hi! I have a web app that has a base page. Each page needs to inherit from this base page as it contains properties they all need as well as dealing with the login rights. My base page has some properties, eg: IsRole1, IsRole2, currentUserID, Role1Allowed, Role2Allowed. On the init of each page I set the properties "Role1Allowed" and "Role2Allowed" Private Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init Role1Allowed = True Role2Allowed= False End Sub The basepage then decides if the user needs redirecting. 'Sample code so not exactly what is going to be, bug gives the idea Protected Overridable Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) If Role1Allowed And Not Role1 Then 'Redirect somewhere End If End Sub The page then must override this pageload if they need anything else in it, but making sure they call the base pageload first. Protected Overrides Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load MyBase.Page_Load(sender, e) If Not IsPostBack Then BindGrid() End If End Sub The other properties (IsRole1, IsRole, currentUserID) are also accessible by the page so it can be decided if certain things need doing based on the user. (I hope this makes sense) Ok so I have 2 questions Should this functionality be in the base page or should it somehow be in the master, and if so how would I get access to all the properties if it was? As there are multiple people working on this project and creating pages some are forgetting to inherit from this basepage, or call the base pageload when overriding it. Is there any way to force them to do this? Thanks for any help. bex

  • Save Xml in an Excel cell value causes ComException

    - by mas_oz2k1
    I am trying to save an object (Class1) as string in a cell value. My issue is that from time to time I have a ComException: HRESULT: 0x8007000E (E_OUTOFMEMORY) (It is kind of random but I have not identified any particular pattern yet) when I write the value into a cell. Any ideas will be welcome For illustration purposes: Let Class1 be the class to be converted to an Xml string. (Notice that I removed the xml declaration at the start of the string to avoid having the preamble present- non printable character) <Class1 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" <ElementID HL690375</ElementID </Class1" Class1 myClass = new Class1(); this class is converted to a string s. s= ConvertObjectToXmlString(myClass); then s is assigned to a cell Range r = Application.ActiveCell; r.Value2 = s; Note: (1) If the string is too big, I limit it to 32000 chars and split the string in chunks of 32000 chars and save the chunks in multiple cells. (2) I do not to quote the string before adding to a cell. Do I need to? If so how it can be done? (3) All object contents are English. (4) C# code sample will be great but VB.net code is OK.

  • Importing Excel spreadsheet data into existing Access DB

    - by Keeb13r
    I've designed an Access 2003 DB with 3 tables: APPLICATIONS, SERVERS, and INSTALLATIONS. Records in the APPLICATIONS and SERVERS tables are uniquely identified by a synthetic primary key (in Access, an "auto number"). The INSTALLATIONS table is essentially a mapping table between APPLICATIONS and SERVERS: it's a list of records of which applications are installed on which servers. A record in the INSTALLATIONS table is also identified by a synthetic primary key, and it consists of an APPLICATION_ID and SERVER_ID for the records in their respective tables. I have an Excel 2003 spreadsheet I would like to import into this database, but it's proving difficult. The spreadsheet is made up of several tabs/worksheets, each one representing a server with its own listing of installed applications. I'm not sure how to proceed with an import - the "Get External Data -- Import" feature in Access has an import "In an Existing Table" option, but it's greyed out. I'm also unsure how I build the relationships between applications and servers for importing records into the INSTALLATIONS table. I had previously fooled around with adding some security to the Access DB file. I think I removed everything but perhaps I didn't and that's causing the problem? Some sample data from the Excel spreadsheet: SERVER101 * Adobe Reader 9 * BMC Remedy User 7.0 * HostExplorer 2008 * Microsoft Office 2003 * Microsoft Office 2007 * Notepad++ SERVER102 * Adobe Reader 9 * DameWare Mini Remote Control * Microsoft Office 2003 * Microsoft .NET Framework 3.5 SP1 * Oracle 9.2 SERVER103 * AWDView * EXTRA! Personal Client 32-bit * Microsoft Office 2003 * Microsoft .NET Framework 3.5 SP1 * Snagit 9.1 * WinZip 12.1 The Access DB design is very simple: APPLICATION * APPLICATION_ID (autonumber) * APPLICATION_NAME (varchar) SERVER * SERVER_ID (autonumber) * SERVER_NAME (varchar) INSTALLATION * INSTALLATION_ID (autonumber) * APPLICATION_ID (number) * SERVER_ID (number)

  • Android: ProgressDialog doesn't show

    - by Select0r
    Hi, I'm trying to create a ProgressDialog for an Android-App (just a simple one showing the user that stuff is happening, no buttons or anything) but I can't get it right. I've been through forums and tutorials as well as the Sample-Code that comes with the SDK, but to no avail. This is what I got: btnSubmit.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { (...) ProgressDialog pd = new ProgressDialog(MyApp.this); pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); pd.setMessage("Working..."); pd.setIndeterminate(true); pd.setCancelable(false); // now fetch the results (...long time calculations here...) // remove progress dialog pd.dismiss(); I've also tried adding pd.show(); and messed around with the parameter in new ProgressDialog resulting in nothing at all (except errors that the chosen parameter won't work), meaning: the ProgressDialog won't ever show up. The app just keeps running as if I never added the dialog. I don't know if I'm creating the dialog at the right place, I moved it around a bit but that, too, didnt't help. Maybe I'm in the wrong context? The above code is inside private ViewGroup _createInputForm() in MyApp. Any hint is appreciated, Greetings, Select0r

  • Jtable live updating problem

    - by Fishinastorm
    Hi all, I'm trying to display a jtable in a pop up Jframe and am running into some problems. What i'am trying to do is as follows: catch a button action event in the main frame and display a pop up frame with a jtable populated with some data. The problem i have is that the jtable is populated with metadata i receive from a website and if i'm receiving many records, then the jtable is not displayed until all the records(metadata) is received from the website. I would like to change it such that as soon as the button event is detected in the main frame, I display the pop up frame along with the jtable and insert/update rows "as and when i receive the data from the website". In another words, i want to display the table and have the records appearing one at a time rather than displaying the jtable only after i receive all records.Below is how i'm trying to do it (but in vain :( ): ......... //add the table to the popup frame when application is started, but don't display the frame `until button action is //detected` extraInfoFrame.add(tblMetadata); extraInfoFrame.setVisible(false); //handle code for button press; display the popup private void butMetadataActionPerformed(java.awt.event.ActionEvent evt) { extraInfoFrame.pack(); extraInfoFrame.toFront(); //frame.setSize(350, 250); extraInfoFrame.setVisible(true); //retrieve rows data for the table for(int i=0;i<len;i++){ Object[] data=new Object[4];data=getMetadata(); //get model and insert row ((javax.swing.table.DefaultTableModel)tblMetadata.getModel()).insertRow(i,data); //tried something to notify the view abt change in table data ((javax.swing.table.DefaultTableModel)tblMetadata.getModel()).fireTableRowsInserted(0, 0); tblMetadata.revalidate(); tblMetadata.repaint(); } } Have been racking my head to try and figure something out. A sample example would be greatly appreciated.

  • InputManager ignores cut/copy/paste when initiated from menu

    - by Wallstreet Programmer
    I'm using the InputManager to check if changes to controls are done by user or code. This works fine, except when user uses the context menu for cut/copy/paste. If the user do ctrl+v in a textbox, InputManager correctly notices it. However, if the paste is done from the context menu of the textbox, the InputManager never fires the PreNotifyInput or PostNotifyInput events. Anyone knows why? Or how to detect that these user actions? Below is a working sample. The lower textblock never gets updated when user uses the cut/copy/paste menu in the above textbox since PreNotifyInput never fires. XAML: <Window x:Class="InputMgrDemo.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <StackPanel> <TextBox TextChanged="TextBox_TextChanged" /> <TextBlock Name="_text" /> </StackPanel> </Window> Code behind: using System.Windows; using System.Windows.Controls; using System.Windows.Input; namespace InputMgrDemo { public partial class Window1 : Window { public Window1() { InitializeComponent(); InputManager.Current.PreNotifyInput += ((sender, e) => _userInput = true); InputManager.Current.PostNotifyInput += ((sender, args) => _userInput = false); } private void TextBox_TextChanged(object sender, TextChangedEventArgs e) { if (_userInput) { _text.Text = (sender as TextBox).Text; } } private bool _userInput; } }

  • AndEngine: Black screen when using LayoutGameActivity

    - by Lemuel Hogben
    I used to use SimpleBaseGameActivity for my app and everything was ok, but now I want to add some ads into the app, so I tried to use LayoutGameActivity. But I get the screen completely black and I don't know why. That's my code: public class AcGame extends LayoutGameActivity { [...] @Override protected int getLayoutID() { return R.layout.ad; } @Override protected int getRenderSurfaceViewID() { return R.id.layout_render; } @Override public EngineOptions onCreateEngineOptions() { [...] return new EngineOptions(true, ScreenOrientation.PORTRAIT_FIXED, resolution, camera); } @Override public void onCreateResources(OnCreateResourcesCallback pOnCreateResourcesCallback) throws Exception { createResources(); pOnCreateResourcesCallback.onCreateResourcesFinished(); } @Override public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback) throws Exception { pOnCreateSceneCallback.onCreateSceneFinished(createScene()); } @Override public void onPopulateScene(Scene pScene, OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception { pOnPopulateSceneCallback.onPopulateSceneFinished(); } And that's my layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="top" android:id="@+id/layout_ad" > <Button android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="Ad Sample"/> </LinearLayout> <org.andengine.opengl.view.RenderSurfaceView android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:id="@+id/layout_render" /> </LinearLayout> When I'm trying to debug, I can see that EngineOptions are creating, but no one of the LayoutGameActivity's methods was called (onCreateResources, onCreateScene or onPopulateScene). Can someone tell me what I've missed?

  • Is there a JSON library that can serialize Proxy objects?

    - by gmoore
    Using ActiveObjects as my ORM and Gson as my JSON processor. Ran into a problem going toJson from persisted objects. The problem is that my persisted class is actually an Interface and AO is proxying that object under the hood. Here's some sample code: Venue venue = manager.get(Venue.class, id); gson.toJson(venue); Comes up with this exception: java.lang.UnsupportedOperationException: Expecting parameterized type, got interface java.lang.reflect.InvocationHandler. Are you missing the use of TypeToken idiom? See http://sites.google.com/site/gson/gson-user-guide#TOC-Serializing-and... Because venue.getClass().getName() gives: $Proxy228 I've tried a few solutions in various combinations: gsonBuilder.registerTypeAdapter(Venue.class, newVenueSerializer()); Type listType = new TypeToken<Venue>() {}.getType(); Nothing has worked so far and I'm using a wonky field-by-field workaround. Any suggestions? I'm not married to Gson, so if there's an alternative library that can do this I'd be happy to use it.
