• (Re)Enabling JavaScript debugger in IE7 with Visual Studio 2008

  - by masterik

  Visual Studio 2008 comes with nice javascript debugging features. But I have played a little with NetBeans debugger wich has installed an ugly Script Debugger from Microsoft to my IE... Normally IE should ask what do I want to use for debugging, but now I can't start debugging with Visual Studio, the Script Debugger is started automatically... After uninstalling the Script Debugger I can't debug in IE at all. Even attaching to iexplore.exe process doesn't helps... Has installed the Script Debugger again... :((((( How can I get back my Visual Studio debugging working in IE again?

• asp.net mvc script and style references

  - by tom

  I'm trying to include script and style references that will not break on deployment, however I can not even get the references to work locally. I have tried using Url.Content() and MVCContrib's <%=Html.ScriptInclude("")%>. My scripts are in a Scripts folder on the root of the site; my styles are in the usual Content/css/ folder. The scripts render like this: <script type="text/javascript" src="/Scripts/MicrosoftAjax.debug.js" ></script> This will not work in a view page in the Views folder. What am I doing wrong and what is the best way to handle this? I would have thought Url.Content() would at least work for styles but used in my master page, the link rendered <link href="/Content/css/Site.css rel="stylesheet" type="text/css" /> This does not work, because the Master Page is in a Shared folder, so what is really the way forward with this?

• Not able to generate correct build.xml for android test project

  - by user338656

  Hi, I have created a main android project using "android" utility. e.g. android create project --target 1 --name MyApp --path C:\testandroid\myui --activity LaunchActivity --package com.myui.activity build.xml got generated fine (has ant targets like debug, release etc) I generated a test android project (which depends on main project). I used "android" utility to do that. e.g. android create test-project --path C:\testandroid\myuitest --main ..\myui --name MfAppTest build.xml got generated but incorrect (does not have targets like run-tests). It has same targets as main project. Can someone help as where is the problem? Thx. Ashley

• Dequeue from messageQueue in the PeekCompleted Method

  - by Fraga

  i'm reading messages from MessageQueue using PeekCompleted, i do my process here and if everything go right, I need to remove it from the Queue! currenty i am using MyMessageQueue.Receive() and it works, but is this a reliable way of making sure each message will be processed right? MessageQueue MyMessageQueue; public Form1() { InitializeComponent(); MyMessageQueue = new MessageQueue(@".\private$\Dms"); MyMessageQueue.PeekCompleted += new PeekCompletedEventHandler(MessageQueue_PeekCompleted); MyMessageQueue.Formatter = new XmlMessageFormatter(new Type[] { typeof(string) }); MyMessageQueue.BeginPeek(); } void MessageQueue_PeekCompleted(object sender, PeekCompletedEventArgs e) { try { Debug.WriteLine("ToProcess:" + e.Message.Body); //Long process that maybe fail MyMessageQueue.Receive(); } finally { MyMessageQueue.BeginPeek(); } }

• GetBytes Issue in Loading External Flash

  - by henry

  I'm trying to debug a gallery section within a site of mine. Currently the section display a number of thumbnails which visitor select one to view. Once selected, the main flash loads in an external swf. To make the process smoother, I have a preloader for this process using normal getbytes codes. However for some reasons, the flash works fine in IE but not in Firefox or Chrome. In these browsers, as soon as you click the thumbnail, the preloader animated away to reveal the holder of the external swf. However as it is still loading, the holder is a blank area. Would appreciate if anyone can shed some light on why this is so.

• Having trouble wrapping functions in the linux kernel

  - by Corey Henderson

  I've written a LKM that implements Trusted Path Execution (TPE) into your kernel: https://github.com/cormander/tpe-lkm I run into an occasional kernel OOPS (describe at the end of this question) when I define WRAP_SYSCALLS to 1, and am at my wit's end trying to track it down. A little background: Since the LSM framework doesn't export its symbols, I had to get creative with how I insert the TPE checking into the running kernel. I wrote a find_symbol_address() function that gives me the address of any function I need, and it works very well. I can call functions like this: int (*my_printk)(const char *fmt, ...); my_printk = find_symbol_address("printk"); (*my_printk)("Hello, world!\n"); And it works fine. I use this method to locate the security_file_mmap, security_file_mprotect, and security_bprm_check functions. I then overwrite those functions with an asm jump to my function to do the TPE check. The problem is, the currently loaded LSM will no longer execute the code for it's hook to that function, because it's been totally hijacked. Here is an example of what I do: int tpe_security_bprm_check(struct linux_binprm *bprm) { int ret = 0; if (bprm->file) { ret = tpe_allow_file(bprm->file); if (IS_ERR(ret)) goto out; } #if WRAP_SYSCALLS stop_my_code(&cs_security_bprm_check); ret = cs_security_bprm_check.ptr(bprm); start_my_code(&cs_security_bprm_check); #endif out: return ret; } Notice the section between the #if WRAP_SYSCALLS section (it's defined as 0 by default). If set to 1, the LSM's hook is called because I write the original code back over the asm jump and call that function, but I run into an occasional kernel OOPS with an "invalid opcode": invalid opcode: 0000 [#1] SMP RIP: 0010:[<ffffffff8117b006>] [<ffffffff8117b006>] security_bprm_check+0x6/0x310 I don't know what the issue is. I've tried several different types of locking methods (see the inside of start/stop_my_code for details) to no avail. To trigger the kernel OOPS, write a simple bash while loop that endlessly starts a backgrounded "ls" command. After a minute or so, it'll happen. I'm testing this on a RHEL6 kernel, also works on Ubuntu 10.04 LTS (2.6.32 x86_64). While this method has been the most successful so far, I have tried another method of simply copying the kernel function to a pointer I created with kmalloc but when I try to execute it, I get: kernel tried to execute NX-protected page - exploit attempt? (uid: 0). If anyone can tell me how to kmalloc space and have it marked as executable, that would also help me solve the above problem. Any help is appreciated!

• How to shutdown local tomcat server when closing browser window?

  - by agez

  Hi, I hava a web app running on a local tomcat server. When the user starts the app (via desktop shortcut) the server starts and the app is opened in a browser window. But when the user just clicks on the close button to stop the application the server is still running in the background - that's annoying. I tried to utilize the "unonload" and "onbeforeunload" events from javascript but unfortunately these events are also fired on some other requests in the app. So I can't use them, except I do a lot of refactoring. Does anyone have an idea for a possible solution? Btw, what I find interesting is the behaviour of Visual Studio when debugging a web application. When I close the browser window Visual Studio also gets a trigger to stop debug mode. So it seems it somehow notices the close event of the browser window, which would be exactly what I need. But I don't know how they do it... Cheers, Helmut

• My app crashes on Iphone SDK 3.2

  - by Mladen

  Hi Guys, My app worked ok on iPhone SDK 3.1. However, when I try to run it in 3.2 simulator, I get the following error and it crashes: bool _WebTryThreadLock(bool), 0x5148280: Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread. Crashing now... Program received signal: “EXC_BAD_ACCESS”. When I debug it, it leads me to this peace of code: - (void)LoginViewToCheckView:(id)sender { CheckViewController *tempTestController = [[CheckViewController alloc] initWithStyle:UITableViewStyleGrouped]; [tempTestController setDelegate:self]; [self setCheckViewController: tempTestController]; [tempTestController release]; [navigationController pushViewController:checkViewController animated:YES];} Other thing worth mentioning is maybe that I am calling this function from a separate thread. Any ideas what could be wrong?

• MySQL IDE recommendation?

  Hello, I've been wondering what you guys are using to write,debug,test your SQL queries there days?

To name a few Mysql Query Browser MySQL Workbench (GA?, Beta?) Eclipse Database development perspective Oracle SQL Developer with Connector/J I won't go into why none of them is perfect, trust me they all have their problems. So, what are you guys using?

• starting .net application from command prompt is having issue when path is in SHORTNAME

  - by ioWint

  when we start our .net application using a double click on the explorer or from command prompt where your folder path is proper full name then there is no issue at all. But when you start it from command prompt with the path being a Shortname involving a ~ the application behaves weird. IF is entering condition though the condition evaluates to FALSE in quick watch. Accessing a value of a variable in quick watch and immediate window shows value. but when you use it to assign to another variable in code, it returns NULL / no value. another observation: when you attach Visual studio to debug the app, and when you go about "Set as next statement" visual studio is giving options to select which dll to work up on. i have never seen this prompt before!

• Why do .png backgrounds appear black on iPhone device but not simulator?

  - by David Rea

  I started with a .tiff file and used GraphicConverter to change it to a .png and set a transparency color. Worked fine in the simulator but when I pushed to the device the transparency color became black. Tested with a .png I downloaded from the net and that worked fine, so it seems to only happen with some files. Thus I suspect it has something to do with the way GraphicConverter writes the .pngs, but I don't know enough about file formats to debug it. Any ideas/suggestions? Ideally I'd like to programatically treat all .pngs because my app allowed dynamic loading of arbitrary files, so I can't verify the transparency beforehand.

• IIS 7 problem which does not occur under apache

  - by cc0

  I'm hosting a little site using a JavaScript to draw a simple graph. It involves one html index file, some css and some js files. It has all been working perfectly on two different apache servers, but when I set up IIS 7 the ajax calls fail. I get no java debug errors in firefox that I can work with, or any kind of error message at all. Without going into the code itself, does anyone have a similar experience with IIS? This is the first time I'm using IIS so I'm not quite sure what to expect to have trouble with. I'd love some input on this, if I have to delve into the code itself I'll make a new thread, I just thought I'd see if this could be a typical issue. Any help is appreciated!

• Import C + Makefile into a linux IDE?

  - by Jessica

  I have a project for Linux that i've been developing for some time. Basically it's a bunch of C and H files together with a directory structure and a Makefile. Every time I need to debug something it's so painful, I need to manually search for var. definitions, structs, etc. Is there any good IDE out there for Linux that will allow me to import those files into a "project" and that will provide code completion or at least an easy way to get my bearings in the source code? thanks!

• ASP.Net mysterious behaviour

  - by kalan

  Does anyone have any idea why this works (expression in the if-clause) if (!(childNode.Roles != null && !Helper.HasEqualElements((string[])childNode.Roles, System.Web.Security.Roles.GetRolesForUser()))) AddNode(childNode, parentNode); And this doesn't if (childNode.Roles == null || Helper.HasEqualElements((string[])childNode.Roles, System.Web.Security.Roles.GetRolesForUser())) AddNode(childNode, parentNode); The problem is that the second if-clause sometimes doesn't work. Though it always works in debug mode, but it sometimes fails while running. And the strange thing is that these two pieces of code seems absolutely equal for me.

• InfoPath browser form submitting dirty fields changed through javascript

  - by Xavier

  I'm trying to submit an InfoPath browser form with fields that have been modified through the Spell Checker included in Sharepoint server. The spell checker checks all the fields in the page and once the user closes the SpellChecker dialog, it changes the textboxes with the new values through javascript. When I click Submit, debug the FormEvents_Submit in the form code behind and try to do a GetNodeValue("XPath to changed field"), it still shows the old values. I realize that this may be a problem of doing postbacks and I'd like to do a full page postback once the SpellChecker is done changing all the textboxes. Any suggestions would be appreciated. Thanks.

• Sharepoint connected web parts question

  - by philj

  I have one web part (the provider) which displays insurance claims in a gridview. When user clicks on one this value(case number) is passed via IWebPartField interface to another web part(consumer) which displays detailed info about the claim. So far so good. I can select different claims in the provider and the details show up in the consumer just fine. The moment I add a TextBox to the consumer, the consumer no longer recognizes the case number passed. I need the user to be able to enter a value in the textbox and click a button to update that claim info. I can debug and attach to process and it looks like it is getting the case in the callback function, etc, but when it is setting parameters for the stored proc in CreateChildControls, it is null. Comment out the TextBox and it works fine. Any clues as to what is going on? Brand new to Sharepoint web parts...any help appreciated! thanks, PhilJ

• Why isn't this simple test class's method inherited in Ruby?

  - by Kevin Bannister

  Consider this very simple logging class: class MockLog def self.log_stub_method(*args) args.each do |a| define_method "#{a}" do |msg| t = Time.now.strftime("%Y-%m-%d %H:%M:%S") $stderr.puts "[#{a.upcase}] \u00bb [#{t}] #{msg}" end end end log_stub_method :fatal, :error, :warn, :info, :debug end Let's add logging to all our classes: class Module def has_logging() class_eval { @log = MockLog.new def log self.class.instance_variable_get :@log end } end end Now, why doesn't this work? class Foo has_logging end Foo.new.log.nil? # => false, as expected class Bar < Foo end Bar.new.log.nil? # => true?! Why wasn't the `log` method inherited?

• Google Calendar title displayed incorrectly

  - by Don

  Hi, I'm creating 2 Google calendars via the Java client API using the following Groovy method: private CalendarEntry createGoogleCalendar(User user) throws ServiceException { new CalendarEntry().with {calendar -> title = new PlainTextConstruct(user.email) summary = new PlainTextConstruct("Collection calendar for $user.email") timeZone = new TimeZoneProperty("America/Montreal") hidden = HiddenProperty.FALSE def savedCalendar = googleCalendar.insert(CALENDAR_URL, calendar) log.debug "Created calendar with title '$savedCalendar.title.plainText' for '$user.email'" return savedCalendar } } The logs show: CalendarService - Created calendar with title '[email protected]' for '[email protected]' CalendarService - Created calendar with title '[email protected]' for '[email protected]' so it appears that all is well. However when I look at the 1st calendar on the Google website, the title is shown as [email protected], though the summary is correctly shown as Collection calendar for [email protected]. Strangely, the title and summary are both shown correctly tor the 2nd calendar. This only started happening today, and I'm pretty sure the relevant code has not changed. I'm totally stumped....

• How do I view Visual Studio BuildLog.htm files without cutting and pasting into an external browser

  - by bgoodr

  This may or may not be specific to VS2005 (as that is the version I'm referring to for this question). I find often the case is that I see this in the Output panel inside Visual Studio 2>Build log was saved at "file://c:\\vsdll_example\MyExecRefsDll\Debug\BuildLog.htm" Now, since that looks and smells like a URL, I would have thought that I could simply left mouse click on it, or left mouse double-click on it, and a browser window of some sort would be displayed. No, that doesn't work. So, to view it, I have to cut and paste the "file://bla/bla/bla" part into an external window. Is there a way to set up Visual Studio to allow me to browse to that file directly, or view it inside Visual Studio IDE, or something to that effect, without the extra fiddling with cutting and pasting? Or is there some type of keybinding I'm not aware of? Thanks, bg

• QWinWidget's position is always 0 (zero)

  - by Kevin

  I hosted a QWinWidget in a CView and want it to stay at a designated position when resizing. But QWinWidget always moves to (0, 0), i.e. left-top corner of the CView. I tried to debug in this way: QWinWidget* pWidget = new QWinWidget(pCView); pWidget->move(50, 50); QPoint pos = pWidget->pos(); Note that: the pos is always (0, 0). Why is that?

• Error preverifying class java during build (BlackBerry)

  - by Davide Vosti

  I'm trying do build and debug a small project for BlackBerry. During the build I'm getting this error Error preverifying class java ... I read on the net this error could be caused by referencing multiple projects but I tried to move every package in a single project but the error is still there. I tried with multiple JDE version (currently 4.7) and the Java compiler is set to 1.6. Eclipse version is 3.4.1 as recommended by RIM's documentations. Does someone have some clue?

• How to get image from relative URL in C#, the image cannot be in the project

  - by red-X

  I have a project where I'm loading relative image Uri's from an xml file. I'm loading the image like this: if (child.Name == "photo" && child.Attributes["href"] != null && File.Exists(child.Attributes["href"].Value)) { Image image = new Image(); image.Source = new BitmapImage(new Uri(child.Attributes["href"].Value, UriKind.RelativeOrAbsolute)); images.Add(image); } Where the "child" object is an XmlNode which could looks like this <photo name="info" href="Resources\Content\test.png"/> During debug it seemd images is filled with actual images but when I want to see them in any way it shows nothing. Weird thing is when I include the images in my project it does work, I however dont want to do that since my point for using an xml file is so that it would be lost since you'd have to rebuild the program anyway after a change.

• Using Assert to compare two objects

  - by baron

  Hi everyone, Writing test cases for my project, one test I need is to test deletion. This may not exactly be the right way to go about it, but I've stumbled upon something which isn't making sense to me. Code is like this: [Test] private void DeleteFruit() { BuildTestData(); var f1 = new Fruit("Banana",1,1.5); var f2 = new Fruit("Apple",1,1.5); fm.DeleteFruit(f1,listOfFruit); Assert.That(listOfFruit[1] == f2); } Now the fruit object I create line 5 is the object that I know should be in that position (with this specific dataset) after f1 is deleted. Also if I sit and debug, and manually compare objects listOfFruit[1] and f2 they are the same. But that Assert line fails. What gives?
