• Debugging a Browser Redirect Loop

  - by just_wes

  Hi all, I am using CakePHP with the Auth and ACL components. My page loads fine for non-registered users, but if I try to log in as a registered user I get an infinite redirect loop in the browser. I am sure that this is some sort of permissions problem, but the problem exists even for users who have permissions for everything. The only way to prevent this behavior is to allow '*' in my AppController's beforeFilter method. What is the best way to debug this sort of problem? Thanks!

• Assigning large UInt32 constants in VB.Net

  - by Kumba

  I inquired on VB's erratic behavior of treating all numerics as signed types back in this question, and from the accepted answer there, was able to get by. Per that answer: Visual Basic Literals Also keep in mind you can add literals to your code in VB.net and explicitly state constants as unsigned. So I tried this: Friend Const POW_1_32 As UInt32 = 4294967296UI And VB.NET throws an Overflow error in the IDE. Pulling out the integer overflow checks doesn't seem to help -- this appears to be a flaw in the IDE itself. This, however, doesn't generate an error: Friend Const POW_1_32 As UInt64 = 4294967296UL So this suggests to me that the IDE isn't properly parsing the code and understanding the difference between Int32 and UInt32. Any suggested workarounds and/or possible clues on when MS will make unsigned data types intrinsic to the framework instead of the hacks they currently are?

• How do Java mocking frameworks work?

  - by Amir Rachum

  This is NOT a question about which is the best framework, etc. I have never used a mocking framework and I'm a bit puzzled by the idea. How does it know how to create the mock object? Is it done in runtime or generates a file? How do you know its behavior? And most importantly - what is the work flow of using such a framework (what is the step-by-step for creating a test). Can anyone explain? You can choose whichever framework you like for example, just say what it is.

• Hibernate object equality checking

  - by Sujee

  As far as I understand(correct me if I am wrong) Hibernate uses object reference to check the object equality. When Hibernate identifies that there are more than one objects attached to same DB record, it throws following exception. "a different object with the same identifier value was already associated with the session" My question is, does Hibernate use equal() method to check the object equality (The default equal method uses object reference)? If it is true, will overridden equal() method change the Hibernate behavior? Note: My question is not about the issues of implementing equal() or hashCode() methods in a Hibernate persisted object. Thank you.

• Flymake quits right ahead after loading with js2-mode

  - by artistoex

  When opening .js files, js2-mode and, subsequently, flymake-js is automatically loaded. But flymake unloads right ahead with the message Toggling flymake-mode off; better pass an explicit argument. However, when enabling it manually, using M-x flymake-mode, it keeps activated. Has anybody encountered similar behavior and has fixed it? My setup: I followed the instructions on emacswiki to set up Flymake to work with the most recent js2-mode with a little modification: (add-hook 'js2-mode-hook '(lambda () (flymake-js-load))) instead of (add-hook 'javascript-mode-hook '(lambda () (flymake-js-load)))

• Eclipse call hierarchy skips calls in undefined #ifdef regions

  - by stupakov

  Hi all, The "call hierarchy" and "declaration" features in Eclipse CDT omit results that exist in undefined (greyed out) #ifdef regions. Example: void blah(void) { #ifndef ABC foo(); #else //line is greyed out bar(); //line is greyed out #endif //line is greyed out } The call hierarchy for foo() will list blah() as a caller; the call hierarchy for bar() will not list blah(). I'm not expecting it to do full resolution of which #define blocks will get compiled, I simply would like it to return all calls/declarations of the function I'm searching for, regardless of the #define blocks that surround it. Other IDEs such as SlickEdit are able to do this. Does anyone know of a way to get Eclipse to adopt this behavior? Thanks.

• Is iOS6 simulator buggy when deleting applications?

  - by davsan

  Frequently, when I try to delete an app on the iOS 6 simulator that comes with Xcode 4.5, the simulator freezes. What I do is just long press on the app. Delete dialog doesn't come up and the icons keep on wiggling. Quitting and re-opening the simulator does not help to delete the app. I've tried to delete the app's folder from /Library/Application Support/iPhone Simulator/5.1/Applications folder. Sometimes this helps but sometimes even this doesn't delete the icon from the simulator. This behavior is independent of the iOS version or the device model. It's the same whichever model/iOS I choose. The only thing that helps is using the Reset Contents and Settings option of the simulator. Do you experience the same frustration? If so, have you figured out a workaround besides resetting the simulator completely?

  What are the pros and cons of the following 2 cases: Case I: Traditional way: Add service reference in project. Create object and Get data from service on server side and bind to asp.net grid. Case II: Update Service for JSON behavior. Add service reference in project. Call service from javascript to get data. Bind data to jquery grid. Which one is the best approach and why?(Not developer point of view) If there is another approach which is more optimized, please explain it.

• jQuery slider widget background -- change dynamicaly

  - by publicRavi

  I use a custom background for my slider by overriding the CSS: .ui-widget-content {background: transparent url(../img/bg.png) no-repeat;} Slider's behavior is controlled by: $(document).ready(function() { $(".myslider5").slider({ animate: "true", step: 1, min: -1950, max: 1950, value: 0, slide: function(event, ui) { // magic happens here } }); There is a need for me to use 2 different classes for my slider DIV, based on some logic. So, myslider5 and myslider3 are the two classes. But their background images need to change too. How do I go about doing this?

• Print styles: How to ensure image doesn't span a page break

  - by notJim

  This is a problem I've had a few times, and I'm not sure how to deal with it. When writing a print stylesheet, is there a way to ensure that an image is always only on a single page. An example of the behavior I'm seeing is below: Page 1 | | | (text text text) | | (text text text) | | ________________ | | | Top of image | | |____________________| ------page break------ ____________________ Page 2 | | Rest of image | | | |________________| | | … | What I'd like Page 1 | | | (text text text) | | (text text text) | | | | | |____________________| ------page break------ ____________________ | ________________ | | | Full image | | | | | | | |________________| | | … | All those times I bitching about floats in LaTeX, and here I am asking for the same functionality... Can this be done? I'm not necessarily concerned about it working in all browsers, since this is often just a one-off document I'm writing to be turned into a PDF.

• DLL response is too slow in Visual Studio [Resolved]

  - by magsto

  I use a 3rd party DLL in my VB.NET project (VS2005) that responds to slow and give wrong values in debug mode. In run-time mode everything works as expected. I do understand that there are something going on in the debug mode which makes the DLL communication slow. This behavior makes it hard to debug the application correctly. Is there any way to force VS to communicate with the DLL in "run-time" mode during debugging but let the rest of the project be in control of the debugger? I found a setting that resolved my issue: Project Properties Debug Enable Debuggers select "Enable unmanaged code debugging". Now the DLL communication flowed smoothly. The DLL I use is a middleware between my app and a USB device. There is no Debug/Release version of the DLL.

• Share Link - Perform action in background

  - by Justin

  I have an application that will accept URLs from the built in web browser via the "Share page" menu item. I'm using the send intent and it works just fine. However, I'd like to accept a URL and process it in the background without bringing my application to the front. I don't want the user to have to actually leave the web browser. It will notify the user it has finished processing the URL with a Toast message. I'm just not sure what type of activity should be used for this. A good example of this behavior is the "Read Later" instapaper application in the android market. Any help would be greatly appreciated.

• issues using facebook iphone api to post image and text

  - by Joey

  I have been trying to use the facebook iphone api to publish an image and some text from my app (i.e. using FBRequest call:@"facebook.stream.publish" with the appropriate params. I've found that the behavior is extremely erratic, as it first worked fine when I implemented it, then, completely stopped working (the request would fail and nothing would show up), and now sometimes posts only the text and most of the time posts only the image in a gallery style (returning a failure). I've read that it's something broken on Facebook's side, however, I see other people's games posting things periodically with images and text and wonder if I might be doing something fundamentally different that is much less reliable or stable. Has anyone encountered such an issue or has more familiarity with this?

• Dynamically adding @property in python

  - by rz

  I know that I can dynamically add an instance method to an object by doing something like: import types def my_method(self): # logic of method # ... # instance is some instance of some class instance.my_method = types.MethodType(my_method, instance) Later on I can call instance.my_method() and self will be bound correctly and everything works. Now, my question: how to do the exact same thing to obtain the behavior that decorating the new method with @property would give? I would guess something like: instance.my_method = types.MethodType(my_method, instance) instance.my_method = property(instance.my_method) But, doing that instance.my_method returns a property object.

• BDD-testing using a UI driver (e.g. Selenium for a web-application)

  - by jonathanconway

  Can BDD (Behavior Driven Design) tests be implemented using a UI driver? For example, given a web application, instead of: Writing tests for the back-end, and then more tests in Javascript for the front-end Should I: Write the tests as Selenium macros, which simulate mouse-clicks, etc in the actual browser? The advantages I see in doing it this way are: The tests are written in one language, rather than several They're focussed on the UI, which gets developers thinking outside-in They run in the real execution environment (the browser), which allows us to Test different browsers Test different servers Get insight into real-world performance Thoughts?

• How to center elements in the BoxLayout using center of the element?

  - by Roman

  I use outputPanel.setLayout(new BoxLayout(outputPanel, BoxLayout.Y_AXIS)); and then I add elements (for example JLabels, JButtons) to the outputPanel. For example: outputPanel.add(submitButton);. I see that all added elements are "centered". It is good, because I do want my elements to be in the center. When I write "center" I mean "equal distance from left and right". But the problem is that the left part of the element is put into the center. And I want to have center of elements to be put into the center. How can I get this behavior?

• need help with db-query on sql-server 2005.

  - by Avinash

  We're seeing strange behavior when running two versions of a query on SQL Server 2005: version A: SELECT otherattributes.* FROM listcontacts JOIN otherattributes ON listcontacts.contactId = otherattributes.contactId WHERE listcontacts.listid = 1234 ORDER BY name ASC version B: DECLARE @Id AS INT; SET @Id = 1234; SELECT otherattributes.* FROM listcontacts JOIN otherattributes ON listcontacts.contactId = otherattributes.contactId WHERE listcontacts.listid = @Id ORDER BY name ASC Both queries return 1000 rows; version A takes on average 15s; version B on average takes 4s. Could anyone help us understand the difference in execution times of these two versions of SQL? If we invoke this query via named parameters using NHibernate, we see the following query via SQL Server profiler: EXEC sp_executesql N'SELECT otherattributes.* FROM listcontacts JOIN otherattributes ON listcontacts.contactId = otherattributes.contactId WHERE listcontacts.listid = @id ORDER BY name ASC', N'@id INT', @id=1234; ...and this tends to perform as badly as version A. Thanks in advance,

• Why a thread is aborted in ASP.NET MVC (again)?

  - by Dario Solera

  Here is what I do in a controller action: create and start a new Thread that does a relatively long processing task (~30 seconds on average, but might be several minutes) immediately return the page response so the user knows processing has started (trivially, a Json with a task ID for polling purposes). At some random point, ThreadAbortException is thrown, so the async task does not complete. The exception is not thrown every time, it just happens randomly roughly 25% of the times. Points to note: I'm not calling Response.End or Response.Redirect - there isn't even a request running when the exception is thrown I tried using ThreadPool and I got the same behavior I know running threads in ASP.NET has several caveats but I don't care right now Any suggestion?

• How to move to a location in a web browser component?

  - by Mostafa Mahdieh

  I have a .NET windows form page and a WebBrowser component inside. I load a page inside the web browser using the Navigate method as in: webBrowser1.Navigate("http://www.stackoverflow.com"); The pages length is longer than the browsers height, so the vertical scroll bar appears. Now I want to move the scrollbar down to a specific position. More specifically I want to search for a specific peace of text inside the page, and scroll to that position. This behavior is implemented in the built-in "Find" function of the browser, but I can't figure out how to call the Find function from within my code, without the Find window appearing. Although I don't want the Find window to appear, if the text matches are highlighted it is welcome.

• How do they do it? Dialogs over home screen.

  - by Brian515

  Hi all, I'm writing an Android application and I would like to place a dialog or view over the home screen so that a user can enter text without jumping into my full application. I can't seem to get this to work. If I present a dialog (even in a transparent activity), my application launches. If you don't know what I'm talking about, take a look at the Facebook widget. I want to replicate a similar behavior to the clicking on the "What's on your mind?" box. Thanks for any help in advance! -Brian

• Powershell equivilent of python's if __name__ == '__main__':

  - by Mark Mascolino

  I am really fond of python's capability to do things like this: if __name__ == '__main__': #setup testing code here #or setup a call a function with parameters and human format the output #etc... This is nice because I can treat a Python script file as something that can be called from the command line but it remains available for me to import its functions and classes into a separate python script file easily without triggering the default "run from the command line behavior". Does Powershell have a similar facility that I could exploit? And if it doesn't how should I be organizing my library of function files so that i can easily execute some of them while I am developing them?

• Same Activity called twice... Issue with Multiple AsyncTasks?

  - by stormin986

  I have three simultaneous instances of an AsyncTask for download three files. When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity. I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack. Could this be from both onPostExecute()s executing simultaneously and both checking the flags each other set at the exact same time? This seems extremely unlikely since two processes would have to be running line-by-line in parallel... *EDIT* A lot removed from this question since I was way off in what I thought was wrong. Nonetheless I found the answer here quite useful, so I have edited the question to reflect the useful parts.

• How to tell the MinGW linker not to export all symbols?

  - by James R.

  Hello, I'm building a Windows dynamic library using the MinGW toolchain. To build this library I'm statically linking to other 2 which offer an API and I have a .def file where I wrote the only symbol I want to be exported in my library. The problem is that GCC is exporting all of the symbols including the ones from the libraries I'm linking to. Is there anyway to tell the linker just to export the symbols in the def file? I know there is the option --export-all-symbols but there seems not to be the opposite to it. Right now the last line of the build script has this structure: g++ -shared CXXFLAGS DEFINES INCLUDES -o library.dll library.cpp DEF_FILE \ OBJECT_FILES LIBS -Wl,--enable-stdcall-fixup EDIT: In the docs about the linker it says that --export-all-symbols is the default behavior and that it's disabled when you don't use that option explicitly if you provide a def file, except when it doesn't; the symbols in 3rd party libs are being exported anyway. EDIT: Adding the option --exclude-libs LIBS doesn't keep their symbols from being exported either.
