  • Animated status bar style transition, a la iPod app

    - by Ben Williamson
    In the iPod app, the navigation views have the default status bar style, and the Now Playing view is in the black style. The transition between them is animated with a crossfade. I want to do that. My first attempt: [UIView beginAnimations:@"whatever" context:nil]; [UIView setAnimationDuration:0.5]; self.navigationController.navigationBar.barStyle = UIBarStyleBlack; [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlack [UIView commitAnimations]; No joy, it pops to black. Takers?

  • Class Not found exception in JApplet.

    - by Nitesh Panchal
    Hello, I created a simple Applet using JApplet and everything seems to work fine but as soon i create an object of my userdefined class named ChatUser in my applet, i get this error :- SEVERE: java.lang.ClassNotFoundException: applet.ChatUser at com.sun.enterprise.loader.ASURLClassLoader.findClassData(ASURLClassLoader.java:713) at com.sun.enterprise.loader.ASURLClassLoader.findClass(ASURLClassLoader.java:626) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:247) at java.io.ObjectInputStream.resolveClass(ObjectInputStream.java:604) at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1575) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1496) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1732) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at misc.ChatClient.run(ChatClient.java:43) Any idea what can be wrong? It only happens when i create an object of any user defined class. Do i need to set some security settings or something? Please help :(

  • Javascript parent page redirection from iframe.

    - by Danil
    Hello to all. I need to implement parent page redirection from iframe. I know that it is impossible to do in different domains due to browsers security. However I found that links have target attribute and tried to use it in the following way: <a href="http://google.com" target="_top" id="testParentRedirect">someLink</a> It works fine if I click this link manually, but I couldn't find cross-browser solution to simulate it using javascript. document.getElementById('testParentRedirect').click(); This works fine in IE, however Firefox and Safary don't know click function :). I tried to work with jquery, but for some reason they don't simulate click event for links. (see following post) I couldn't find any appropriate solution on stackoverflow. Maybe someone could help me in it. I will appreciate it. :)

  • How to find what ActiveX control is referred on a web page?

    - by Sly
    I have developed a web application (ASP.NET Web Forms). One of my customer has very restrictive policies. When he accesses the web page, IE shows this message: Your security settings do not allow Web sites to use ActiveX controls installed on your computer. This page may not display correctly. As far as I know, we don't use ActiveX controls on our page. I did a "View Souce" and did not find anything suspect. How can I find what part of my page refers to an ActiveX. The application uses jQuery and a few jQuery plug-ins. Is there a tool/add-in like "Fire Bug" that I can use to list the ActiveX controls referred on a page?

  • Assign multiple Emacs keybindings to a single command?

    - by Dan
    I'm giving ErgoEmacs mode a try to see if I can use Emacs more comfortably. Some of its keybindings are fairly intuitive, but in many cases I don't want to outright replace the defaults. For example, in the context of ErgoEmacs' navigation shortcut structure, M-h makes sense as a replacement for C-a--but I want to be able to use both, not just M-h. I tried simply duplicating the commands: ;; Move to beginning/ending of line (defconst ergoemacs-move-beginning-of-line-key (kbd "C-a")) ; original (defconst ergoemacs-move-end-of-line-key (kbd "C-e")) ; original (defconst ergoemacs-move-beginning-of-line-key (kbd "M-h")) ; ergoemacs (defconst ergoemacs-move-end-of-line-key (kbd "M-H")) ; ergoemacs But Emacs simply overwrites the first keybinding with the second. What's the best way to address this?

  • Popuplating an NSPopupButton with the contents of two NSArrayControllers

    - by ndg
    I'm looking to populate an NSPopupButton with the contents of two NSArrayControllers. The NSArrayControllers are both bound to my Core Data Managed Object Context and represent separate entities (in this example: Person and Department). Within my NSPopupButton, I would like a list of departments, and the people that work under them. Like so: Department 1 Person 1 Person 2 Department 2 Person 3 Person 4 All departments would need to be disabled by default, meaning that users should only be able to select people listed within the dropdown. I'm lost as to how I would go about doing something like this. The concept of manually populating an NSPopupButton seems fairly trivial, but I'm a bit shaky as to best to populate the element with Core Data objects. Essentially, I'm just looking for someone to point me in the right direction. I imagine there's a right way to do this, and a number of very wrong ways.

  • Common Programming Jargon

    - by jdk
    What programming terms have you coined (or heard) that have taken off in your own circles (i.e. have heard others repeat it)? It might be within your own team, workplace or garnered greater popularity on the Internet. Write your programming term, word or phrase in bold text followed by an explanation, citation and/or usage example so we can use it in appropriate context. Please no repeats of common jargon already ingrained in the programming culture like: "kludge", "automagically", "cruft", etc. (unless you coined it). Stealing from the comments: "A shared vocabulary is the basis of communication, not just among programmers [...]"

  • align WMD editor's preview HTML with server-side HTML validation (e.g. no embedded javascript)

    - by Justin Grant
    There are many SO questions (e.g. here and here) about how to do server-side scrubbing of Markdown produced by the WMD editor to ensure the HTML generated doesn't contain malicious script, like this: <img onload="alert('haha');" src="http://www.google.com/intl/en_ALL/images/srpr/logo1w.png" /> This doesn't affect the WMD client's preview box. I doubt this is a big deal since if you're scrubbing the HTML on the server, an attacker can't save the bad HTML so no one else will be able to see it later and have their cookies stolen or sessions hijacked by the bad script. But it's still kinda odd to allow an attacker to run any script in the context of your site, and it's probably a bad idea to allow the client preview window to allow different HTML than your server will allow. StackOverflow has clearly plugged this hole. How did they do it? [NOTE: I already figured this out but it required some tricky javascript debugging, so I'm answering my own question here to help others who may want to do ths same thing]

  • svn for eclipse on mac os lion

    - by camdaochemgio
    I need to use Subversion with Eclipse on Mac Lion. I encounter problem as below I saw: Subclipse in Mac OS Lion In my context: I use Mac OS Line 10.7.2 Eclipse version: 3.7.1 64 bit I install Subversion: Universal Subversion 1.6.17 Binaries for Lion (Mac OS X 10.7) in the page: http://www.open.collab.net/downloads/community/ I install Subclipse by the "Install New Software..." feature of Eclipse with the update link: http://subclipse.tigris.org/update_1.8.x It install Subclipse 1.8.2, JavaHL 1.7.1.1 and some other packages. When I go to menu Preferences/ Team / SVN , it produce error: "Incompatible JavaHL library loaded. 1.7.x or later required." I find to install SVN Kit, so use it instead of JavaHL as the very first link refer (here), but I don't see it in Subclipse package.

  • Sanitize HTML before storing in the DB or before rendering? (AntiXSS library in ASP.NET)

    - by user102533
    I have an editor that lets users add HTML that is stored in the database and rendered on a web page. Since this is untrusted input, I plan to use Microsoft.Security.Application.AntiXsSS.GetSafeHtmlFragment to sanitize the HTML. Should I santiize before saving to the database or before rendering the untrusted input into the webpage? Is there an advantage in including the AntiXSS source code in my project instead of just the DLL? (Maybe I can customize the white list?) Which class file should I look in for actual implementation of the GetSafeHtmlFragment

  • How to create commandlink programmatically

    - by John
    Hi, We have a system built on seam/richfaces. There's this webpage where the tables are rendered from dynamic context (from multiple different datasources, and each of them uses a different layout to represent essentially the same real world concept). As a result, this table is binded to a bean, and it's columns/layout are generated from this bean. Now I need to add a command link on a specific column, equivalent to <a4j:commandLink value="#{actBean.Ids}" action="#{actBean.genDetails}"> <f:setPropertyActionListener target="#{actBean.Ref}" value="#{cont}"/> </a4j:commandLink> in a JSF page. My question is, how do I do this programmatically? Thanks!

  • How can I request local pages in the background of an ASP.NET MVC app?

    - by flipdoubt
    My ASP.NET MVC app needs to run a set of tasks at startup and in the background at a regular interval. I have implemented each task as a controller action and listed the app-relative path to the action in the database. I implemented a TaskRunner process that gets the urls from the database and requests each one at a regular interval using WebRequest.Create, but this throws a UriFormatException. I cannot use this answer or any code that plucks values from HttpContext.Current.Request without getting an HttpException with the message "Request is not available in this context". The Request object is not available because my code uses System.Threading.Timer to do background processing, as recommended here. Here are my questions: Is there really no way to make local web requests within an ASP.NET web app? Is there really no way to dynamically ascertain the root path to the web app even using static dependencies in ASP.NET? I was trying to avoid storing the app's root path in the database (as FogBugz does with its "Maintenance Path"), but is this best option?

  • My AES encryption/decryption functions don't work with random ivecs

    - by Brendan Long
    I was bored and wrote a wrapper around openSSL to do AES encryption with less work. If I do it like this: http://pastebin.com/V1eqz4jp (ivec = 0) Everything works fine, but the default ivec is all 0's, which has some security problems. Since I'm passing the data back as a string anyway, I figured, why not generate a random ivec and stick it to the front, the take it back off when I decrypt the string? For some reason it doesn't work though. With random ivec: http://pastebin.com/MkDBFcn6 Well actually, it almost works. It seems to decrypt the middle of the string, but not the beginning or end: String is: 0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF Encrypting.. ???l%%1u???B! ?????`pN)?????[l????{?Q???2?/?H??y"?=Z?Cu????l%%1u???B! Decrypting.. String is: ?%???G*?5J?0??0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF!-e????V?5 I honestly have no idea what's going wrong. Maybe some stupid mistake, or maybe I'm missing something about AES?

  • How has test first development changed the way you write software?

    - by Toran Billups
    I've started to find that I can't write software without writing a test first. I ask this subjective question because I want to hear what others in the community think about the reasons I can't go back to writing production code without a test first. If you can't write a test for something you don't understand it Without a regression test you can't clean the code You are going to test it anyway, spend the time to do it right Evolutionary design is possible without fear You actually write less code yourself Fast feedback cycles save time and money Job security (less bugs makes your boss happy) It actually makes my work more enjoyable

  • "Out of Memory" error in Lotus Notes automation from VBA

    - by PowerUser
    This VBA function sporadically fails with a Notes automation error "Run-Time Error '7' Out of Memory". Naturally, when I try to manually reproduce it, everything runs fine. Function ToGMT(ByVal X As Date) As Date Static NtSession As NotesSession If NtSession Is Nothing Then Set NtSession = New NotesSession NtSession.Initialize End If (do stuff) End function To put this in context, this VBA function is being called by an Access query, 3-4 times per record, with 20,000 records. For performance reasons, the NotesSession has been made static. Any ideas why it is sporadically giving an out-of-memory error? (Also, I'm initiating the NotesSession just so I can convert a datetime to GMT using Lotus's rules. If you know a better way, I'm listening).

  • How to run an .exe application in another computer?

    - by ADAM
    I am working on a C# application in Visual Studio 2013. When I run the .exe file from my computer, the application runs very well and all the features work. When I tried to run the .exe on another computer, the database side doesn't work well and the connection with the database couldn't be opened. The SqlConnection is constructed as follows: SqlConnection cn = new SqlConnection("Data Source=ADAM-PC;Initial Catalog=integrationdatabase;Integrated Security=True" I don't know how to change the data source to make the connection with the database established in another computer. How can I solve this problem?

  • Dependency issue in inheritance chain

    - by Razer
    I have a class in coffeescript a class layout like the following. class @A foo: -> console.log('foo') class @B extends A fooB: -> @foo() class @C extends B fooC: -> @foo() I tried this in interpreters, it works. However it raises errors, when executing this in the browser (all of them are in separate coffee files, and are used in a global context. Therefore the @ before the class): Uncaught ReferenceError: B is not defined application.js It seems that B is defined after the definition of C. How can this happen?

  • Aes key length significance/implications

    - by cppdev
    Hi, I am using a AES algorithm in my application for encrypting plain text. I am trying to use a key which is a six digit number. But as per the AES spec, the key should be minimum sixteen bytes in length. I am planning to append leading zeros to my six digit number to make it a 16 byte and then use this as a key. Would it have any security implications ? I mean will it make my ciphertext more prone to attacks. Please help.

  • Implementing a 'Send Feedback' feature in a Java desktop application

    - by William
    I would like to implement a 'Send Feedback' option in a Java desktop application. One which will pop up a box for the user to enter a comment, then send it to us along with a screenshot of the application window. How would be the best way to communicate the data to us? Two obvious solutions spring to mind: Email - I'm thinking that the application would connect to an SMTP server set-up by us, with the username/password somehow hidden in the code. SMTP over SSL for security (not of the data being sent, but of the SMTP username/password). Web service - pretty self explanatory. Which of these would be best, or is there a better alternative?

  • How to retrieve all errors and messages from a query using ADO

    - by Johan Levin
    When a SQL batch returns more than one message from e.g. print statements, then I can only retrieve the first one using the ADO connection's Errors collection. How do I get the rest of the messages? If I run this script: Option Explicit Dim conn Set conn = CreateObject("ADODB.Connection") conn.Provider = "SQLOLEDB" conn.ConnectionString = "Data Source=(local);Integrated Security=SSPI;Initial Catalog=Master" conn.Open conn.Execute("print 'Foo'" & vbCrLf & "print 'Bar'" & vbCrLf & "raiserror ('xyz', 10, 127)") Dim error For Each error in conn.Errors MsgBox error.Description Next Then I only get "Foo" back, never "Bar" or "xyz". Is there a way to get the remaining messages?

  • anonymous access disabled but...

    - by Melody Friedenthal
    My web app (asp VB 2005) uses Windows authentication. If the user isn't part of a specific AD security group they don't get to edit the data; instead I redirect the user to a read-only page. The program works fine in the IDE. I published the web app to my laptop and Disabled anonymous access. When I ran the program I got redirected to the read-only page. I added a write event to the application event log to see what was going on, and found that the WindowsPrincipal.Identity.Name contained my laptop's ID, not my user name. I reassert: anonymous access is disabled in IIS and the web.config file has Windows Authentication. Can anyone suggest what else to check? Or can you explain what's going on?

  • Mobile Application Upgrade/Update Framework

    - by sharjeel
    I am developing a few mobile apps for different platforms including Blackberry, Windows Mobile, Android and Symbian S60. I want my mobile apps to have the capability of checking for updates before starting and in case a new version is available, prompt the user to upgrade. Moreover in certain cases (like security patches), the user must be forced to update or the app won't work. Surely I can cook some code to achieve the task but I was wondering if there are already existing framework to serve the purpose so that I don't have to re-invent the wheel and test all over?

  • Is it secure to use malloc?

    - by Felix Guerrero
    Somebody told me that allocating with malloc is not secure anymore, I'm not a C/C++ guru but I've made some stuff with malloc and C/C++. Does anyone know about what risks I'm into? Quoting him: [..] But indeed the weak point of C/C++ it is the security, and the Achilles' heel is indeed malloc and the abuse of pointers. C/C++ it is a well known insecure language. [..] There would be few apps in what I would not recommend to continue programming with C++."

  • Writing a custom auth system (like the default django auth system), use it to generate tables in DB

    - by dotty
    Hay all, I've been reading up on middleware and how to use it with a context object. I want to write a simple middleware class which i can use on my own applications, it will essentially be a cut down version of the django one. The problem i seem to have is that if i have INSTALLED_APPS = ('django.contrib.my_auth') in the settings file, all is well. I've also added MIDDLEWARE_CLASSES = ('django.contrib.my_auth.middleware.MyAuthMiddleware') in it and everything is fine. My question is, how would i make my middleware automatically generate tables from a models.py module, much like how the django auth does when i run manage.py syncdb? thanks
