• Using Components.utils.import in a firefox extension

  - by jamesatha

  I am trying to create some global variables in a firefox extension. In my content folder, I have two javascript files: 1) Main JS file that holds the functions for the different events, etc 2) A file that stores only an object with the pieces of state I want to maintain. Also, I set the array EXPORTED_SYMBOLS. I am having issues with the following line found in my main JS file: Components.utils.import("resource:///globalVariables.js"); When it is at the top of the file, nothing seems to work. If I move it into the function where I need the variable, the rest of my code works, but the function with this line does nothing. Any advice that would help me with this problem would be great. Thanks

• Using pipes inside a class in C++

  - by Paul

  I'm trying to use this tutorial to make plots with Gnuplot in C++. However I will be using the pipe to Gnuplot from within a class, but then I run into some problems: I've got a header file where I declare all variables etc. I need to declare the pipe-variable here too, but how do I do that? I've tried doing it straight away, but it doesn't work: Logger.h: class Logger { FILE pipe; } Logger.cpp: Logger::Logger() { //Constructor *pipe = popen("gnuplot -persist","w"); } Gives the error Logger.cpp:28: error: no match for ‘operator=’ in ‘*((Logger*)this)->Logger::pipe = popen(((const char*)"gnuplot -persist"), ((const char*)"w"))’ Suggestions?

• How do I get the current Application Name (in terms of IIS) in a classic asp Web application

  - by Mr AH

  I have a classic asp application which retrieves the current application name and sets an Application variable containing that name. This name is important (I wont go into why) and is essentially the friendly name in IIS. The problem is, the implementation used to get this name is flawed, it a) assumes the home directory contains the string wwwroot, and b) assumes the folder name is the same as the application name. I can no longer guarantee these conditions. I would have thought the application name is know at run-time but I can't seem to find it in either Session or Application variables (at application start up entry point in global.asa). Any ideas?

• Does C++ require a destructor call for each placement new?

  - by Josh Haberman

  I understand that placement new calls are usually matched with explicit calls to the destructor. My question is: if I have no need for a destructor (no code to put there, and no member variables that have destructors) can I safely skip the explicit destructor call? Here is my use case: I want to write C++ bindings for a C API. In the C API many objects are accessible only by pointer. Instead of creating a wrapper object that contains a single pointer (which is wasteful and semantically confusing). I want to use placement new to construct an object at the address of the C object. The C++ object will do nothing in its constructor or destructor, and its methods will do nothing but delegate to the C methods. The C++ object will contain no virtual methods. I have two parts to this question. Is there any reason why this idea will not work in practice on any production compiler? Does this technically violate the C++ language spec?

• php array regular expressions

  - by bell

  I am using regular expressions in php to match postcodes found in a string. The results are being returned as an array, I was wondering if there is any way to assign variables to each of the results, something like $postcode1 = first match found $postcode2 = second match found here is my code $html = "some text here bt123ab and another postcode bt112cd"; preg_match_all("/([a-zA-Z]{2})([0-9]{2,3})([a-zA-Z]{2})/", $html, $matches, PREG_SET_ORDER); foreach ($matches as $val) { echo $val[0]; } I am very new to regular expressions and php, forgive me if this is a stupid question. Thanks in advance

• Is it safe to unset PHP super-globals if this behavior is documented?

  - by Stephen

  I'm building a PHP framework, and in it I have a request object that parses the url as well as the $_GET, $_POST and $_FILE superglobals. I want to encourage safe web habits, so I'm protecting the data against SQL injection, etc. In order to ensure users of this framework are accessing the safe, clean data through the request object, I plan to use unset($_GET, $_POST, $_REQUEST); after parsing those variables. I will document this in the method comments, and explain in the framework documentation that this is happening. My question is: Would this be desirable behavior? What are the potential pitfalls that I have not foreseen?

• Accessing php $_SESSION from python (wsgi) - is it possible?

  - by Bill Zimmerman

  Hi, I've got a python/WSGI app which needs to check to see if a user has logged on to a PHP web app. The problem is that the PHP app checks if a user has logged on by comparing a value in the $_SESSION variable to a value in the cookie from the user's browser. I would prefer to avoid changing the behavior of the php app if at all possible. My questions: Is there anyway I can access the session variables from within python? Where should I start to look? Are there any obvious security/performance issues I should be aware of when taking this approach?

• is right to implement a business logic in the type binding DI framwork?

  - by Martino

  public IRedirect FactoryStrategyRedirect() { if (_PasswordExpired) { return _UpdatePasswordRedirectorFactory.Create(); } else { return _DefaultRedirectorFactory.Create(); } } This strategy factory method can be replaced with type binding and when clause: Bind<IRedirect>.To<UpdatePasswordRedirector>.When(c=> c.kernel.get<SomeContext>().PasswordExpired()) Bind<IRedirect>.To<DefaultRedirector>.When(c=> not c.kernel.get<SomeContext>().PasswordExpired()) I wonder which of the two approaches is the more correct. What are the pros and cons. Especially in the case in which the logic is more complex with more variables to test and more concrete classes to return. is right to implement a business logic in the binding?

• how do you find the exact variable of a null pointer exception

  - by OVERTONE

  I've been at this one for a bit now. I've got a null pointer exception so im guessing somethings not been initialized. AdminMessages.inbox1.setText(messageRsetArray[0]); thats my code where its targetting. but i cant find what inside it hasnt been initiazed. AdminMessages is a class which contains a JTextField called inbox1, messageRsetArray is an array which has taken variables from an array. also inbox1 is static. i coulndt get the getters and setter to work. i know its bad practice though.

• PHP split string into integer element and string

  - by David19801

  Hello, I have a string say: Order_num = "0982asdlkj" How can I split that into the 2 variables, with the number element and then another variable with the letter element in php? The number element can be any length from 1 to 4 say and the letter element fills the rest to make every order_num 10 characters long in total. I have found the php explode function...but don't know how to make it in my case because the number of numbers is between 1 and 4 and the letters are random after that, so no way to split at a particular letter. Please help as specifically as possible!

• Breaking from for loop in MATLAB GUI

  - by Nick

  I have a for loop in the opening function of a GUI in MATLAB and I'm trying to use a callback button to break the loop. I'm new to MATLAB. Here's the code I have: %In the opening function of the GUI handles.stop_now = 0; for i=1:inf if handles.stop_now==1 break; end end % Executes on button press function pushbutton_Callback(hObject, eventdata, handles) % hObject handle to end_segmenting_button (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) handles.stop_now=1; guidata(hObject, handles); For some reason, despite defining the variables with handles, the loop doesn't break upon pressing the button. Anyone know what's going on? Thanks.

• Question about inserting assembly code in C++

  - by Bruce

  I am working on VC++ compiler. I want to accomplish the following The variables s.AddrFrame.Offset and s.AddrStack.Offset contain the value of EBP and ESP respectively. I want to extract the value of old EBP and the return address. Assuming the address EBP + 1 contains the old 32 bit EBP value and EBP + 5 the return address I wrote the following code: unsigned int old_ebp = 0; unsigned int ret_addr = 0; __asm{ mov old_ebp, DWORD PTR [s.AddrFrame.Offset + 1] mov ret_addr, DWORD PTR [s.AddrStack.Offset + 5] } But this is not compiling xxxx.cpp(1130) : error C2415: improper operand type Please Help

• How to handle dependency files in a cross-platform manner?

  - by Brian Knoblauch

  I'm working on updating an old app. It has some dependency files that live in the same directory as the app. Obviously this broke when Windows Vista came out (since it violates the API and Vista/7 now enforce that (XP didn't)). Ideally, I'd like to avoid hardcoding anything into the app for just Windows. I can live with that if I have to though. I've already been down that path with pulling the APPDATA and LOCALAPPDATA environment variables, but that doesn't help any since they just give you the current user area... I need these to live somewhere accessible for all users, and I'd like to obey the Windows API expectations that they go into the all user appdata area. Suggestions?

• Sort Java List/Map by order in which items are in an XML File

  - by Brandon Smith

  Hello everyone, What I'm looking to do is to sorta a Java List or Map in the order the items are in a XML File. For Example I have a list of function names as so: functionOne functionThree functionTwo The XML File looks like this: <xml> <function>functionOne</function> <function>functionTwo</function> <function>functionThree</function> </xml> So I would like to sort the list so the function names are as so: functionOne functionTwo functionThree Now Im trying to do this for Variables as well, so there are around 500+ unique 'items'. Does anyone have any idea how I can go about doing this? Now for the file that determines that sort order doesn't have to be XML it just what I use the most, it can be anything that can get the job done. Thanks in advance for your time.

• Debugging Drupal 6

  - by coach_rob

  OK, I've read and attempted all of the tutorials I can find on being able to debug a locally installed Drupal 6 instance. I'm on Windows, 32-bit. I have access to Eclipse (obviously) as well as Visual Studio 2005/2008. I've yet to be able to get any of the Eclipse options (XDebug, Zend, etc.) working to be able to step through code, inspect variables, etc. I've heard good things about VS.PHP, but haven't committed to the $100 or whatever it is. Can some of your PHP/Drupal gurus out there tell me the best, simplest, most reliable way to debug Drupal and PHP on the Windows platform?

• Is this an injection attempt or a normal request?

  - by CheeseConQueso

  In cPanel's Analog Stats statistics module, I've noticed countless requests to connect to the following example: /?x=19&y=15 The numbers are random, but its always setting x and y variables. Another category of mysterious requests: /?id=http://nic.bupt.edu.cn/media/j1.txt?? There are other attempts at injections in the request log that have straight sql written into them as well. Example: /jobs/jobinfo.php?id=-999.9 UNION ALL SELECT 1,(SELECT concat(0x7e,0x27,count(table_name),0x27,0x7e) FROM information_schema.tables WHERE table_schema=0x73636363726F6F745F7075626C6963),3,4,5,6,7,8,9,10,11,12,13-- It looks like they are all reaching a 404, but I'm still wondering about the intent behind these. I know this is vague, but maybe someone knows that this is normal while using cPanel & phpMyAdmin services. Also, there was a search box installed on the site which could be the reason. Any suggestions as to what all these are?

• Efficient bitshifting an array of int?

  - by nn

  Hi, To be on the same page, let's assume sizeof(int)=4 and sizeof(long)=8. Given an array of integers, what would be an efficient method to bitshift the array to either the left or right? I am contemplating an auxiliary variable such as a long, that will compute the bitshift for the first pair of elements (index 0 and 1) and set the first element (0). Continuing in this fashion the bitshift for elements (index 1 and 2) will be computer, and then index 1 will be set. I think this is actually a fairly efficient method, but there are drawbacks. I cannot bitshift greater than 32 bits. I think using multiple auxiliary variables would work, but I'm envisioning recursion somewhere along the line.

• What is the difference between an object's scope and it's context in javascript?

  - by DKinzer

  In the vernacular, scope and context have a lot in common. Which is why I get confused when I read references to both, such as in the quote below from an article on closures: Scope refers to where variables and functions are accessible, and in what context it is being executed. (@robertnyman) As far as I can tell, context is just a reference to an object. Can someone please explain what exactly is context, as used, for instance, in the jQuery syntax, $(selector, context). And is an object's scope the same at it's context?

• MySQL thousands of updates, slowing down.

  - by noryb009

  I need to run a PHP loop for a total of 100, 000 times (about 10, 000 each script-run), and each loop has about 5 MySQL UPDATES to it. When I run the loop 50 times, it takes 3 sec. When I run the loop 1000 times, it takes about 1300 sec. As you can see, MySQL is slowing down ALOT with more UPDATEs. This is an example update: mysql_query("UPDATE table SET `row1`=`row1` +1 WHERE `UniqueValue`='5'"); This is generated randomly from PHP, but I can store it in a variable and run it every n loops. Is there any way to either make MySQL and PHP run at a consistent speed (is PHP storing hidden variables?), or split up the script so they do? Note: I am running this for a development purposes, not for production, so there will only be 1 computer accessing the data.

• PHP export to text file - Only saving first line.

  - by wertz8090

  I'm trying to export some extracted $_POST information into a text file, however my code is only capturing the first variable and ignoring the rest. I'm saving the information to the text file in this manner: $values = "First Name: $fName\r\n"; $values .= "Last Name: $lName\r\n"; $values .= "Address: $address\r\n"; etc. This is the code I use to write to the text file: $fp = @fopen("person.data", "w") or die("Couldn't open person.data for writing!"); $numBytes = @fwrite($fp, $values) or die("Couldn't write values to file!"); @fclose($fp); Any ideas on why it would only save the first $values ($fName) variable but not the rest of them? It actually saves the first part of the $values string for all of them (so I see Last Name:, Address:, etc. on separate lines in the text file) but the called variables $lName and $address do not appear.

• Nested for_each with lambda not possible?

  - by Ela782

  The following code does not compile in VS2012, it gives error C2064: term does not evaluate to a function taking 1 arguments on the line of the second for_each (line 4 below). vector<string> v1; for_each(begin(v1), end(v1), [](string s1) { vector<string> v2; for_each(begin(v2), end(v2), [](string s2) { cout << "..."; }); }); I found some related stuff like http://connect.microsoft.com/VisualStudio/feedback/details/560907/capturing-variables-in-nested-lambdas which shows a bug (they are doing something different) but on the other hand that shows that what I print above should be possible. What's wrong with the above code?

• Getting access to a custom Master page from a user control

  Hi We have created a Master page that inherits off the asp.net Master class. We have also got ui controls that inherit off the standard asp.net ui control class. Our Master page has a public member variable. We need to be able to access that member variable from the ui controls that we use. However we can't seem to get at it? Is it our architecture that is wrong? Or the idea itself - user control getting acces to Master page variables?

• FETCH INTO doesn't raise an exception if the set is empty, does it?

  - by Cade Roux

  Here is some actual code I'm trying to debug: BEGIN OPEN bservice (coservice.prod_id); FETCH bservice INTO v_billing_alias_id, v_billing_service_uom_id, v_summary_remarks; CLOSE bservice; v_service_found := 1; -- An empty fetch is expected for some services. EXCEPTION WHEN OTHERS THEN v_service_found := 0; END; When the parametrized cursor bservice(prod_id) is empty, it fetches NULL into the three variables and does not throw an exception. So whoever wrote this code expecting it to throw an exception was wrong, right? The comment seems to imply that and empty fetch is expected and then it sets a flag for later handling, but I think this code cannot possibly have been tested with empty sets either. Obviously, it should use bservice%NOTFOUND or bservice%FOUND or similar.
