• sfConfig::get is not returning constants defined in app.yml

  - by morpheous

  I have an interesting problem. I am using Symfony 1.3.2. I have defined some constants in project/apps/frontend/config/app.yml and project/config/app.yml When I use the constant (correct spelling) in a piece of code like this $test=sfConfig::get('app_foobar'); the variable $test is assigned a null value. This is what I have checked so far: CHECK: cache files generated? (YES) CHECK: Do the cache files (config_app.yml.php) in the cache directory contain the constants defined in the app.yml file (YES) CHECK: Constant names used in the code matches the array keys found in config_app.yml? (YES) At this stage, I have run out of ideas. I dont want to supply a default value as a hack, because when I need to change the value of the constant, I will have to replace this in potentially hundreds of instances (too error prone). Is there anything that I have missed?. What could be causing this?

• How do you get the ID of a control in ASP.NET

  - by James

  I am attempting to loop through an array of numbers, match them to the checkbox they they are associated with, and checkmark that box. My checkbox is set up like: <input type="checkbox" runat="server" id="someID" name="somename" value="1234" /> My code when the page loads currently looks like: foreach (string interest in interests_Var){ foreach (var c in Page.Controls) { } } interests_Var is my array containing different numbers. We'll assume one of them is 1234. While looping through the page controls, I want to compare the value of the control to my number. If it equals my number, I want to then apply the attribute checked="checked". I'm assuming I have to find the ID of the control I am using, then use that ID to add a new attribute. Or is there a way I can add the attribute using the c variable? I'm not dead set on this setup, so if you know a better way, I'm all ears. Thanks for any help and suggestions.

• Simple XML parsing error

  - by phpeffedup

  I'm trying to iterate through a Twitter XML File, where the container tag is , and each user is . I need to create a variable $id based on the XML attribute for each user. Username is already instantiated. $url = "http://api.twitter.com/1/statuses/friends/$username.xml"; $xmlpure = file_get_contents($url); $listxml = simplexml_load_string($xmlpure); foreach($listxml->users->children() as $child) { $id = $child->{"id"}; //Do another action } But I'm getting this error: Warning: main() [function.main]: Node no longer exists in /home/.../bonus.php on line 32 Line 32 is the foreach statement, and I don't actually USE the main() method.

• What is a practical use for a closure in JavaScript?

  - by alex

  I'm trying my hardest to wrap my head around JavaScript's closures. I get that by returning an inner function, it will have access to any variable defined in it's immediate parent. Where would this be useful to me? Perhaps I haven't quite got my head around it yet. Most of the examples I have seen online don't provide any real world code, just vague examples. Can someone show me a real world use of a closure? Is this one, for example? var warnUser = function (msg) { var calledCount = 0; return function() { calledCount++; alert(msg + '\nYou have been warned ' + calledCount + ' times.'); }; }; var warnForTamper = warnUser('You can not tamper with our HTML.'); warnForTamper(); warnForTamper(); Thanks

• Passing a web service an unknown number of parameters

  - by Billyhole

  I'm relatively new to utilizing web services. I'm trying to create one that will be accepting data from a ASP.Net form whose input controls are created dynamically at runtime and I don't how many control values will be getting passed. I'm thinking I'll be using jQuery's serialize() on the form to get the data, but what do I have the web service accept for a parameter? I thought maybe I could use serializeArray(), but still I don't know what type of variable to accept for the JavaScript array. Finally, I was thinking that I might need to create a simple data transfer object with the data before sending it along to the web service. I just didn't wanna go through with the DTO route if there was a much simpler way or an established best practice that I should follow. Thanks in advance for any direction you can provide and let me know I wasn't clear enough, or if you have any questions.

• Segfault when calling a method c++

  - by shuttle87

  I am fairly new to c++ and I am a bit stumped by this problem. I am trying to assign a variable from a call to a method in another class but it always segfaults. My code compiles with no warnings and I have checked that all variables are correct in gdb but the function call itself seems to cause a segfault. The code I am using is roughly like the following: class History{ public: bool test_history(); }; bool History::test_history(){ std::cout<<"test"; //this line never gets executed //more code goes in here return true; } class Game{ private: bool some_function(); public: History game_actions_history; bool local_variable; }; bool Game::some_function(){ local_variable = game_actions_history.test_history(); if (local_variable == true){ return true; } else{ return false; } } Any tips or advice is greatly appreciated!

• make db connection persistent throught zend framework

  - by kamikaze_pilot

  I'm using zend framework. currently everytime I need to use the db I go ahead and connect to the DB: function connect(){ $connParams = array("host" => $host, "port" => $port, "username" => $username, "password" => $password, "dbname" => $dbname); $db = new Zend_Db_Adapter_Pdo_Mysql($connParams); return $db } so I would just call the connect() function everytime I need to use the db My question is...suppose I want to reuse $db everywhere in my site and only connect once in the very initial stage of the site load and then close the connection right before the site gets sent to the user, what would be the best practice to accomplish this? Which file in Zend should I save $db in, what method should I use to save it (global variable?), and which file should I do the connection closing in?

• Can a pointer ever point to itself?

  - by eSKay

  This question was mentioned here. My doubt is: If a pointer variable has the same address as its value, is it really pointing to itself? For example - in the following piece of code, is a a pointer to itself? #include<stdio.h> int main(){ int* a; int b = (int)&a; a = b; printf("address of a = %d\n", &a); printf(" value of a = %d\n", a); } If a is not a pointer to itself, then the same question poses again: Can a pointer point to itself? Also, how is a self pointing pointer useful?

• Problems with Ruby "||" "or"?

  - by Kevin

  Beginning Ruby Question: I'm trying to see if a string variable's contents is either "personal" "email" or "password". I'm trying: if params[:action] == "password" || "email" || "personal" foo else don't foo end But that doesn't work and returns strange results, and using IRB to play around with "or" statements I have no idea why the following happens: irb(main):040:0> a = "email" => "email" irb(main):041:0> a == "password" || "email" => "email" irb(main):042:0> a == "email" || "password" => true I just want something that if any of the 3 variables are true no matter what order they are in it returns true, if not it returns false. Anyone want to help this n00b out?

• static const double in c++

  - by Crystal

  Is this the proper way to use a static const variable? In my top level class (Shape) #ifndef SHAPE_H #define SHAPE_H class Shape { public: static const double pi; private: double originX; double originY; }; const double Shape::pi = 3.14159265; #endif And then later in a class that extends Shape, I use Shape::pi. I get a linker error. I moved the const double Shape::pi = 3.14... to the Shape.cpp file and my program then compiles. Why does that happen? thanks.

• Force close Android application Phone.apk in landscape mode

  Standard Android application Phone.apk with an outgoing call on the tenth of a second can use the landscape screen mode, but if you make a modification of graphic resources, in landscape mode the phone is closed with an error, Eclipse shows it - E / AndroidRuntime (2888): java.lang.RuntimeException: Unable to start activity ComponentInfo {com.android.phone / com.android.phone.InCallScreen}: java.lang.ClassCastException: android.view.AbsSavedState $ 1.

• Setting Environment Variables For NMAKE Before Building A 'Makefile Solution'

  - by John Dibling

  I have an MSVC Makefile Project in which I need to set an environment variable before running NMAKE. For x64 builds I needs to set it to one value, and for x86 builds I need to set it to something else. So for example, when doing a build I would want to SET PLATFORM=win64 if I'm building a 64-bit compile, or SET PLATFORM=win32 if I'm building 32-bit. There does not appear to be an option to set environment variables or add a pre-build even for makefile projects. How do I do this? EDIT: Running MSVC 2008

• What's the equivalent in C# of this VB code on an Outlook form?

  - by wes

  Basically, how do I link an Outlook form and a C# back end? In VB you can write on the form Sub ButtonName_Click() Dim Recipients With Item.GetInspector.ModifiedFormPages("Message") Set Recipients = .Controls("To") End With End Sub which will fire whenever the button named "ButtonName" on the form is clicked and will set the variable Recipients to a string of whatever is in the To text box. Now I have a custom form, and I have a VS C# Outlook Add-in, and they're two separate things. I've got an event handler that can catch MailItem objects, but I don't know how to handle custom form button clicks or even how to access elements on the form. EDIT - Just to clarify, the custom form was created in Outlook and then its .ofs was imported into VS. Both Outlook and VS are 2010.

• Dreamweaver recordset filter - Display all records as default

  - by Drew

  I am trying to create a simple search form to filter the results in the dynamic table. The search form is on the same pages as the results and posts to itself. I get the search string from the post variable. It is working, but I can't figure out how to set the default value to display all results. Dreamweaver automatically sets the default value to -1, and therefore no results are displayed on the initial load. How do I change this to display ALL records as default and the filter only if there is search string defined.

• git, SSH_ASKPASS on windows

  - by Martin Schreiber

  I am writing a graphical git frontend for Linux and Windows (MSEgit) based on MSEide+MSEgui. MSEgit has an internal console window which communicates with git by pipes. On Linux it uses a PTY so SSH asks for key unlocking passwords on the PTY. On Windows I wrote a small password entry application and set the SSH_ASKPASS environment variable accordingly. SSH calls the password application if git is started with CreateProcess() dwCreationFlags DETACHED_PROCESS set but the password entry window will not be focused, its taskbar icon flashes instead. SSH does not run the password application if FreeConsole() is called to be sure that there is no attached console to MSEgit and git is started without DETACHED_PROCESS but CREATE_NO_WINDOW instead. I assume a Windows equivalent of POSIX setsid() should be called. How can I force SSH to use SSH_ASKPASS without the DETACHED_PROCESS flag? If this is not possible, how can I ensure that the password entry window is focused?

• How do you debug c/c++ source code in linux using emacs?

  - by vmihai

  Hello all, I am using emacs and autotools, to write and compile c/c++ sources on linux. I am using gdb via GUD in emacs. I have defined for convenience: F7:compile, F10:gud-next, F11:gud-step, F5:gud-cont, F9:gud-tbreak, F8:gud-until, F4:gud-print. I am mainly interested in debugging c/c++ source code on linux from emacs and I would like to get the most gdb can give. Unfortunately I am using only F4 which prints the variable under cursor. So my question is how do you guys debug the source code ? What programs do you use ? What key bindings (functionality) do you use mostly ? What do you need the debugger to do for you ? If you do weird stuff it doesn't matter. I would like to know everything to boost my speed a bit here. Thanks in advance. Mihai

• ivar is inside two blocks

  - by Desperate Developer

  I have an ivar like this declared on interface: BOOL controllerOK; I have to use this ivar inside a block that resides itself in a block. Something like myBlockl = ^(){ [self presentViewController:controller animated:YES completion:^(){ if (controllerOK) [self doStuff]; }]; }; If I try to do that, I see an error capturing self strongly in this block is likely to lead to a retain cycle for the if (controllerOK) line. This does not appear to be one of those blocks problems that you create another variable using __unsafe_unretained before the block starts. First because this instruction cannot be used with a BOOL and second because the ivar controllerOK has to be tested on runtime inside the block. Another problem is that the block itself is declared on the interface, so it will be used outside the context where it is being created. How do I solve that?

• How can CopyOnWriteArrayList be thread-safe?

  - by Shooshpanchick

  I've taken a look into OpenJDK's sources of CopyOnWriteArrayList and it seems that all write operations are protected by the same lock and read operations are not protected at all. As I understand, under JMM all accesses to a variable (both read and write) should be protected by lock or reordering effects may occur. For example, set(int, E) method contains these lines (under lock): /* 1 */ int len = elements.length; /* 2 */ Object[] newElements = Arrays.copyOf(elements, len); /* 3 */ newElements[index] = element; /* 4 */ setArray(newElements); The get(int) method, on the other hand, only does return get(getArray(), index);. In my understanding of JMM, this means that get may observe the array in an inconsistent state if statements 1-4 are reordered like 1-2(new)-4-2(copyOf)-3. Do I understand JMM incorrectly or is there any other explanations on why CopyOnWriteArrayList is thread-safe?
