• POST data disapearing on large file upload

  - by DfKimera

  I'm having issues with a file uploading utility in my PHP application. When sending large files (9MB+) over the form, I get a very odd behaviour: the POST data I've included in the form dissapears, including the file information. I've already increased all PHP limits I could (time limit, max input time, post max size, memory limit and upload max filesize) and I still can't get the proper behaviour. I've tried replacing the regular HTTP forms with a Flash-based solution (SWFUpload, www.swfupload.org), still the same behaviour. I've tried multiple files of similar sizes and its definitely not a particular file issue. I've debugged the POST vars sent using Firebug, and the correct variables are still there in the header, together with the file. What could be going on here?

• reading a file that doesn't exist

  - by John

  Hi, I have got a small program that prints the contents of files using the system call - read. unsigned char buffer[8]; size_t offset=0; size_t bytes_read; int i; int fd = open(argv[1], O_RDONLY); do{ bytes_read = read(fd, buffer, sizeof(buffer)); printf("0x%06x : ", offset); for(i=0; i<bytes_read; ++i) { printf("%c ", buffer[i]); } printf("\n"); offset = offset + bytes_read; }while(bytes_read == sizeof(buffer)); Now while running I give a file name that doesn't exist. It prints some kind of data mixed with environment variables and a segmentation fault at the end. How is this possible? What is the program printing? Thanks, John

• How do I dynamically assign the Model for a .find in Ruby on Rails?

  - by Angela

  I am trying to create a Single Table Inheritance. However, the Controller must be able to know which class to find or create. These are based on another class. For example, ContactEvent with type = Letter needs to grab attributes from a corresponding Model called Letter. Here's what I've tried to do and hit a snag, labelled below. I need to be able to dynamically call assign a value of EventClass so that it can be Letter.find(:conditions =) or Calls.find(:conditions =) depending on which type the controller is acting on. def new @contact_event = ContactEvent.new @contact_event.type = params[:event_type] # can be letter, call, postcard, email @contact_event.event_id = params[:event_id] # that ID to the corresponding Model @contact_event.contact_id = params[:contact] @EventClass = case when @contact_event.type == 'letter' then 'Letter' when @contact_event.type == 'call' then 'Call' when @contact_event.type == 'email' then 'Email' SNAG BELOW: @event = @EventClass.find(@contact_letter.letter_id) #how do I make @EventClass actually the Class?SNAG # substitution of variables into the body of the contact_event @event.body.gsub!("{FirstName}", @contact.first_name) @event.body.gsub!("{Company}", @contact.company_name) @evebt.body.gsub!("{Colleagues}", @colleagues.to_sentence) @contact_event.body = @event.body @contact_event.status = "sent" end

• Error Instantiating an Inner Class in Parent's Constructor...

  - by stormin986

  In my application's main class (subclass of Application), I have a public inner class that simply contains 3 public string objects. In the parent class I declare an object of that inner class. public class MainApplication extends Application { public class Data { public String x; public String y; public String z; } private Data data; MainApplication() { data = new Data() data.x = "String"; } } After I instantiate the object in the constructor, I get a runtime error when I try to assign any of the inner class object's variables. Any idea what's up here??

• wordpress filters documentation? Trying to understand add_filter()

  - by Chris J. Lee

  I read over the documentation several times and have been having a hard time trying to figure out what is going on with the function. I'm more and more confused after looking at the documentation, looking over the source code as well. add_filter($tag, $hook, $priority, $args); it seems to me the new function extends the parent function. What puzzle's me is what parts of the hook becomes overridden. in some examples in the documentation i see that some variables are replaced with the $args in your new $tag. I almost understood it all here: http://www.andrewnacin.com/2010/05/18/rethinking-template-tags-in-plugins/ but then i couldn't figure out how you pass arguments and which eventually get overriden. thanks in advance.

• How do I get the current location of an iframe?

  - by studiothat

  I have built a basic data entry application allowing users to browse external content in iframe and enter data quickly from the same page. One of the data variables is the URL. Ideally I would like to be able to load the iframes current url into a textbox with javascript. I realize now that this is not going to happen due to security issues. Has anyone done anything on the server side? or know of any .Net browser in browser controls. The ultimate goal is to just give the user an easy method of extracting the url of the page they are viewing in the iframe It doesn't necessarily HAVE to be an iframe, a browser in the browser would be ideal. Thanks, Adam

• Passing an array of data to a private function in CodeIgniter/PHP? [facepalm]

  - by Jack Webb-Heller

  So I thought this should be easy, but, I'm n00bing out here and failing epicly (as they say on teh interwebz). So here's my code: function xy() { $array['var1'] = x; $array['var2'] = y; echo $this->_z; } function _z($array) { $xy = $x.$y; return $xy; } So, why doesn't that seemingly simple code work? I know with views you can pass arrays and the variables are accessible in the views with just their array title, but, why doesn't it work in this case? Jack

• Lambda expressions and nullable types

  - by Mathew

  I have two samples of code. One works and returns the correct result, one throws a null reference exception. What's the difference? I know there's some magic happening with capturing variables for the lambda expression but I don't understand what's going on behind the scenes here. int? x = null; bool isXNull = !x.HasValue; // this works var result = from p in data.Program where (isXNull) select p; return result.Tolist(); // this doesn't var result2 = from p in data.Program where (!x.HasValue) select p; return result2.ToList();

• Displaying Fields (and/instead of Properties) in a PropertyGrid

  - by Jenk

  I'd like to use a PropertyGrid to manipulate the data on some objects, however these objects don't have properties, they have fields. Thus a property grid doesn't display them (high five MS!) Before anyone posts "just use properties": I can't at the moment.. these objects are DTOs and are used to send data to a VB6 Interop dll, thus all the parameters for the method calls are "ref" parameters (high five MS!), and C# won't compile if you use a property instead of a field or variable (high five MS!). No, I am not going to create local variables for every property on any given object. There many, many fields, and many, many test cases that would need updating, as well as the production code it self, and this post/question may be the path of least resistance. :)

• design patterns for hierarchical structures

  - by JLBarros

  Anyone knows some design patterns for hierarchical structures? For example, to manage inventory categories, accounting chart of accounts, divisions of human resources, etc.. Thank you very much in advance EDIT: Thanks for your interest. I am looking for a better way of dealing with hierarchical items to which they should apply operations depending on the level of hierarchy. I have been studying the patterns by Martin Fowler, for example Accounting, but I wonder if there are other more generic. The problem is that operations apply to the items must be possible to change even at run time and may depend on other external variables. I thought of a kind of strategy pattern but would like to combine it with the fact that it is a hierarchical scheme. I would appreciate any reference to hierarchical patterns and you'll take care of them in depth.

• Wpf application variable not changing

  - by Hasan Zubairi

  In my application I need some variables on almost all the pages so I declared them in Application.xaml like <sys:String x:key="First">First</sys:String> and on one page I change the value in code like Resources["First"] = "This is First"; on the second page when I call the variable like String f = (string)this.TryFindResource("First"); MessageBox.Show(f); the out put is "First" and not "This is First". I also tried like. Application.Current.Properties["First"]

• MySQL Locking table from Stored FUNCTION

  - by Brandon

  I have a function in a MySQL Database that determines some sync parameters for a mobile device. The function determines the last date/time the user synchronized with the database. During my sync operation I call this server side function twice. As soon as I call it the second time - the entire Sync_Records table is locked. I cannot write to it from any other connection anywhere (note, after first call, the table is not locked). I changed the function to a Procedure - and all is fine - no locking after the second call. The entire sync operation (including both calls to the function/procedure) is within a transaction. This is an InnoDb table. The function/procedure simply does two select statements. They are storing results in local variables and then returning the date time variable. I don't understand why the tables are locked. Does anyone have any ideas?

• PHP Convert variable names to lowercase?

  - by VeeBee

  I have an api listener script which takes in get parameters. But I seem to be having issues when users tend to pass mixed case variable names on the parameters. For example: http://mylistenerurl.com?paramName1=Hello&paramname2=World I need my listener to be flixible in such a way that the variable names will be interpreted case-insensitively or rather still all in lower case like after I process the query string on some function, they are all returned as lower-cased variables: extract(someFunction($_GET)); process($paramname1, $paramname2); Can anybody shed some light on this? *much appreciated. thanks!

• Is there any significant benefit to reading string directly from control instead of moving it into a

  - by Kevin

  sqlInsertFrame.Parameters.AddWithValue("@UserName", txtUserName.txt); Given the code above...if I don't have any need to move the textbox data into a string variable, is it best to read the data directly from the control? In terms of performance, it would seem smartest to not create any unnecessary variables which use up memory if its not needed. Or is this a situation where its technically true but doesn't yield any real world results due to the size of the data in question. Forgive me, I know this is a very basic question.

• TeamCity's build agent unable to find PowerShell

  - by cincura.net

  I have TC's build agent installed on Windows 2008 R2 SP1 Core. The server has PowerShell 2.0 installed (double checked, and actually from PS downloaded the TC installation). Looking at some build configuration I see these being incompatible with this agent, because powershell_x86/powershell_x64 is required. I tried deleting build agents dirs to force upgrade, but no luck. Interestingly if I provide powershell_x86, powershell_x86_Path (and for 64bit) variables into config file manually, everything runs fine. Is there anything I can do to have the build agent find PowerShell automatically? What/where is it looking for it? Maybe the 'Core' is problem.

• Autorelease with elements in a UITableViewCell - memory leak

  - by Shaun Budhram

  In my 'cellForRowAtIndexPath' method for a UITableView delegate, I'm allocating a cell if it doesn't exist, and in this cell, I'm creating a new activity spinner like so: UIActivityIndicatorView *actView = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray ] autorelease]; I'm using Leaks to detect memory leaks in my program, and for some reason, this is coming up as a leak, even though it's autoreleasing. The cell itself is also autoreleasing. Has anyone had experience with autoreleasing variables coming up as leaks in the Leaks instrument, and how to tackle these problems? Also, if it helps, this is the history Leaks is displaying for this memory location. It looks like it at some point gets an additional retain message? This is not being done in my code.

• Commenting out protect_from_forgery

  - by Andy

  Hi, I was trying to use active record store but I kept getting an invalid authenticity token. Someone told me to remove my protect_from_forgery from application controller. I know that this would remove all auth tokens but I'm not sure if this is a good idea. Does active record store not need auth tokens? By the way, all I need is a way to dynamically calculate the number of users online and their session variables. If there is a better way than using active record store it would be nice to know.

• Is it possible to programmatically control c# health monitoring without using the web.config file?

  - by Adam

  I have developed my own custom provider for the health monitoring; however, I use parameters in the constructor and this is not allowed when using the health monitoring from the web.config file. Does anyone know if I can turn on/off the monitoring and have it watch properly through code (possibly in my global.asax file on application startup). Or, is it possible for me to create my own watcher that will do the same thing as the health monitor. Or, finally - can I just pass variables from the web.config setup (i'm not familiar with the public token part of the provider type declaration). Thanks in advance

• How do I splice a python string programmatically?

  - by Robin Welch

  Very simple question, hopefully. So, in Python you can split up strings using indices as follows: >>> a="abcdefg" >>> print a[2:4] cd but how do you do this if the indices are based on variables? E.g. >>> j=2 >>> h=4 >>> print a[j,h] Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: string indices must be integers

• Run batch file when argument contains quotes and spaces (from .NET framework)

  - by turtle

  I have a bat file which sets some environment variables, and then executes a command on the command line. I want to replace the hard coded command with one passed in via a parameter. So: :: Set up the required environment SET some_var=a SET another_var=b CALL some.bat :: Now call the command passed into this batch file %1 The problem is that the command is complex, and doesn't escape cleanly. It looks like this: an.exe -p="path with spaces" -t="some text" -f="another path with spaces" I'm trying to call the .bat from a .NET framework app, using: Dim cmd as String = "the cmd" System.Diagnostics.Process.Start( thebat.exe, cmd ) but I can't seem to get the escapes to work correctly. Can someone tell me how the string cmd should be entetered to get the command passed into the bat file as an argument correctly?

• POSIX Threads and signal masks

  - by Max

  Is there a way to change the signal mask of a thread from another thread? I am supposed to write a multithreaded C application that doesn't use mutex, semaphores and condition variables, only signals. So it would look like something like this: The main Thread sends SIGUSR1 to its process and and one of the 2 threads (not including the main thread), will respond to the signal and block SIGUSR1 from the sigmask and sleep. Then the main thread sends SIGUSR1 again, the other thread will respond, block SIGUSR1 from its sigmask, unblock SIGUSR1 from the other threads sigmask, so it will respond to SIGUSR1 again. So essentially whenever the main thread sends SIGUSR1 the two other threads swap between each other. Can somebody help?

• Can EPD Python and MacPorts Python coexist on OS X (matplotlib)?

  - by bjoern

  I've been using MacPorts Python 2.6 on OS X 10.6. I am considering also installing the Enthought Python Distribution (EPD) on the same machine because it comes preconfigured with matplotlib and other nice data analysis and visualization packages. Can the two Python distributions co-exist peacefully on the same machine? What potential problems will I have to look out for (e.g., environment variables)? I know that building matplotlib through MacPorts is an option, but the process is lengthy (on the order of a full day) and there are open questions about compiling some dependencies on 64bit Intel. I would like to know about the tradeoffs before committing to one of the two approaches.

• Can this example be done with pointers instead of global variable?

  - by Louise

  This is a simplified example of the problem I have: #include <stdio.h> #include <stdlib.h> void f2(int** a) { printf("a: %i\n", **a); } void f1(int* a) { f2(&a); } int main() { int a = 3; f1(&a); // prints "a: 3" f2(???); return 0; } The problem is that I would like to be able to use f2() both in main() and in f1(). Can that be done without using global variables?

• Good code visualization / refactoring tools for C++?

  - by Paul D.

  I've found myself coming across a lot of reasonably large, complicated codebases at work recently which I've been asked to either review or refactor or both. This can be extremely time consuming when the code is highly concurrent, makes heavy use of templates (particularly static polymorphism) and has logic that depends on callbacks/signals/condition variables/etc. Are there any good visualization tools for C++ period, and of those are there any that actually play well with "advanced" C++ features? Anything would probably be better than my approach now, which is basically pen+paper or stepping through the debugger. The debugger method can be good for following a particular code path, but isn't great for seeing the big picture you really need when doing serious refactoring. EDIT: I should mention that Visual Studio plugins aren't going to be a lot of help to me, since our stuff is mostly Linux-only.
