  • Perl, FastCGI and writing uploaded files

    - by ibogdanov
    My upload function looks like: sub Upload_File{ my ($file, $mime, $description) = @_; my $file_name = param('filename'); my $data; $file = UnTaint($file); if ($mime =~ /text/) { sysopen(VAULT, "$path/$file", O_RDWR | O_EXCL | O_CREAT | O_TEXT) or die "couldn't create $file for R/W: $!\n"; } else { sysopen(VAULT, "$path/$file", O_RDWR | O_EXCL | O_CREAT | O_BINARY) or die "couldn't create $file for R/W: $!\n"; } my $upfh = \*VAULT; flock $upfh, 2; seek $upfh, 0, 0; select((select($upfh), $| = 1)[0]); while( sysread($file_name, $data, 8192) ) { syswrite($upfh, $data, 8192) or die "couldn't write $upfh: $!\n"; } close $upfh; } When I am using read and print with FastCGI upload script, files uploaded with corruptions (including simple text files), this is because perl uses buffered I/O. But when I use syswrite and sysread i.e. non-buffered I/O, as a result I get good text files, but binary files are corrupted anyway.

  • C++ split string

    - by Mike
    I am trying to split a string using spaces as a delimiter. I would like to store each token in an array or vector. I have tried. string tempInput; cin >> tempInput; string input[5]; stringstream ss(tempInput); // Insert the string into a stream int i=0; while (ss >> tempInput){ input[i] = tempInput; i++; } The problem is that if i input "this is a test", the array only seems to store input[0] = "this". It does not contain values for input[2] through input[4]. I have also tried using a vector but with the same result.

  • Why use C typedefs rather than #defines?

    - by me_and
    What advantage (if any) is there to using typedef in place of #define in C code? As an example, is there any advantage to using typedef unsigned char UBYTE over #define UBYTE unsigned char when both can be used as void func() { UBYTE byte_value = 0; /* Do some stuff */ return byte_value; } Obviously the pre-processor will try to expand a #define wherever it sees one, which wouldn't happen with a typedef, but that doesn't seem to me to be any particular advantage or disadvantage; I can't think of a situation where either use wouldn't result in a build error if there was a problem.

  • Rspec > testing database views

    - by Sean McCleary
    How can database views be tested in Rspec? Every scenario is wrapped in a transaction and the data does not look like it is being persisted to the database (MySQL in my case). My view returns with an empty result set because none of the records are being persisted in the transaction. I am validating that the records are not being stored by setting a debug point in my spec and checking my data with a database client while the spec is being debugged. The only way I can think to have my view work would be if I could commit the transaction before the end of the scenario and then clear the database after the scenario is complete. Does anyone know how to accomplish this or is there a better way? Thanks

    Hi, I have a XML file with a few concert dates. In my flash/AS3 file, I would like to show only the up coming event, relative to current date. Like this: Event 01: 30-05-2010 Event 02: 02-06-2010 Event 03: 05-06-2010 Today is 28-05-2010, so I need to list Event 01. On 01-06-2010 I need to list Event 02. I have the basic AS3 code for listing the XML working, but I'm having trouble filtering the result. Any ideas? Thanks.

    Hi, I got the code below that is trying to load an image from the web into an Image control, when I run it I get an error on the given line that no network access is allowed: private void button1_Click(object sender, RoutedEventArgs e) { WebClient webClientImgDownloader = new WebClient(); webClientImgDownloader.OpenReadCompleted += new OpenReadCompletedEventHandler(webClientImgDownloader_OpenReadCompleted); webClientImgDownloader.OpenReadAsync(new Uri("http://dilbert.com/dyn/str_strip/000000000/00000000/0000000/000000/80000/5000/100/85108/85108.strip.print.gif", UriKind.Absolute)); } void webClientImgDownloader_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e) { BitmapImage bitmap = new BitmapImage(); bitmap.SetSource(e.Result); // ERROR HERE! image1.Source = bitmap; } Silverlight for Windows Phone 7

  • linq2sql left join with "multiselect"

    - by just_azho
    Hi, folks I'm trying to achieve following by linq2sql, but not successful. I've Member and Reference tables. DB is design in such a manner that Member can have multiple (=0) References. What I want as a result of query is, list (rows) of members, where all references of the member are "collected" in one column. What I had achieved is following query, but for this one there exist a row for each Reference. var refs = (from m in db.Members join r in db.References on m.PID equals r.PID into g from o in g.DefaultIfEmpty() select new { member = m, name = (o == null ? "" : o.NameSurname) }); I feel I need to insert SelectMany somewher :) Could you please give hints on achieving the goal?

  • iOS sdk question: how do I cast a UIView to a UIImage View (alternativly how do I get a UIImageView from a GestureRecognzer?)

    - by user439299
    Desired end result: user taps a UIImageView and the image changes to another image (a subsequent tap returns the image to the original state) Problem: I add a (unique) selector to a bunch of UIImageViews (in an array) and point the action at the same function - let's call this function imageTapped: for now. Here is my code so far: -(void)imageTapped:(UITapGestureRecognizer *)tapGesture { UIImageView *view = tapGesture.view; // rest of code... } This code actually works fine but gets a warning when I run it: "Incompatible objective c types initilizing 'struct UIView *', expected 'struct UIImageView *' Any way to get rid of this? Not sure how casting works in objective c... primitive types seem to work fine such as (int)someFloat works fine but (UIImageView)someUiView doesn't work. Like I said, code works alright when I run it but would like to get ride of the compiler warning. Any help would be awesome.... I am very new to objective c (or any non java language for that matter) so be gentle. Thanks in advance.

  • asp.net could a half submitted web page be processed?

    - by c00ke
    Having a weird bug in production and just wondering if it's possible for a half submitted web page to processed by the server? The page has no view state just using plain old html controls and accessing data displayed in repeater on the back end via Request.Form[name] etc. Is it possible for a request to be truncated perhaps due to lost internet connection and the page still processed by the server. Therefore if field not part of the request Request.Form[name] could result in null? I know can use fiddler to modify request but unfortunately we are not allowed to change group policy and change the proxy! Many Thanks

  • Need guidance for my first Android application: how many activities should I use?

    - by jul
    Hi, I'm starting Android doing an application for searching restaurants, and some guidance would be welcome! On the first screen I'd like to have a search field with a submit button (I get the data from a web service), and below a list with the results of the search. When clicking on one of the items of the list it will show a screen with the restaurant details as well as a map showing its location. My questions are: Can I do everything in one single activity or should I do an activity for the search, one for the result list, one for the restaurant description, and another for the map? Would doing one single activity make the application more responsive? How can I use a list and a map within a normal activity (without ListActivity and MapActivity)? Any help, pointer, example application or sample code is very appreciated! Thank you Jul

  • WPF Logical Tree - bottom up vs. top down

    - by Dor Rotman
    Hello, I've read the MSDN article about the layouts pass, that states: When a node is added or removed from the logical tree, property invalidations are raised on the node's parent and all its children. As a result, a top-down construction pattern should always be followed to avoid the cost of unnecessary invalidations on nodes that have already been validated. Now lets assume I do this. Won't the users see the control tree populate itself and the layout change several times during the control creation process? I want the whole control tree to just appear completely full. Thanks!

  • aspectRatio = backingWidth / backingHeight ???

    - by carrots
    What am I doing wrong here, I can't get the result of this division: aspectRatio = backingWidth / backingHeight; I've thought I might try casting to (GLfloat) but that didn't do anything. As I step through the code I see that aspectRatio is 0 after the operation, while backingWidth is clearly 768 and backingHeight is 1029. Here are the types: GLfloat aspectRatio; and // The pixel dimensions of the CAEAGLLayer GLint backingWidth; GLint backingHeight; It must be something basic I'm doing wrong here..

  • Is git revert broken?

    - by sabgenton
    The following pastebin is a repo with one file with one, two, three, four, five typed on each line. Each line was commited separately into git: http://pastebin.ca/raw/2136179 I then tried to delete the line two with the command git revert <commmit which creates two> And get: error: could not revert b4e0a66... second hint: after resolving the conflicts, mark the corrected paths hint: with 'git add <paths>' or 'git rm <paths>' hint: and commit the result with 'git commit' There should be no conflict for something this simple? Or am I doing it wrong/got the wrong command? The merge details don't seem to make sense either: one <<<<<<< HEAD two three four five ======= >>>>>>> parent of b4e0a66... second Isn't that saying delete everything but one? I was expecting only two to be affected... git 1.7.10

  • Conditional Branching Issues

    - by Zack
    Here is the code: def main_menu print_main_menu user_selected = gets.chomp if user_selected.downcase == "no" main_menu elsif user_selected == "1" || "2" || "3" || "4" || "5" || "6" || "7" user_selected = user_selected.to_i call_option(user_selected) else main_menu end end This code uses calls to allow a user to make a selection from a main menu. Depending on the input, be it a certain number, a certain word, or something else, the respective method is called (in the case of a valid input) or the main menu is printed again (in the case of an invalid input or "no"). My questions are twofold. 1) Is there an efficient way to get rid of the literal string error that appears as a result of this redundant or statement on the elsif line? (the code itself works fine, but this error appears and is frustrating). 2) When an alternate/unspecified input is made by the user, the else branch doesn't execute and main_method doesn't start over. I have no idea why this is happening. Is there something I'm missing here? Thanks

  • toupper/tolower + locale (german)

    - by Oops
    Hi, how to convert a string (wstring) from lowercase to uppercase characters and vice versa? I searched the net and found there is a STL-function std::transform. But until now I hav'nt figured out how to give the right locale-object for example "Germany_german" to the function. Who can help please? my code looks like: wstring strin = L"ABCÄÖÜabcäöü"; wstring str = strin; locale loc( "Germany_german" ); // ??? how to apply this ??? std::transform( str.begin(), str.end(), str.begin(), (int(*)(int)tolower ); //result: "abcäöüabcäöü" The characters ÄÖÜ and äöü (it's like Ae, Oe, Ue) will not be converted correctly. P.S.: I don't prefer a big switch sweat and also I know BOOST is capable of everything, i would prefer a STL solution. thanks in advance Oops

  • Can return and else statements be used interchangable in CFScript?

    - by Mel
    I would like to know your opinion on using return and else statements interchangeably in CFScript. I generally use the following syntax: if (something) { // Do something } else { // Do something else } It recently occurred to me I could do this instead: if (something) { // Do something return; } // Do something else Would those two styles yield a different end result? I like not having to wrap code in an else statement. My thinking is that if the if statement evaluates true and returns, the code below it will not run. If it does not evaluate true, then the code below it will run regardless of whether it is wrapped in an else statement or not. Does that sound write?

  • CI controller function is ignored

    - by den-javamaniac
    Hi. I'm trying to pass through a CI tutorial (writing a simple forum) and I can't make a controller function called. To be more specific I have this in a controller: function __construct() { parent::Controller(); $this->load->helper('url'); } function index() { $data['title'] = "Wlcome to Gossip"; $data['heading'] = "Welcome to Gossip"; $data['query'] = $this->db->get('topic')->result(); $this->load->view('welcome', $data); } function topic() { echo 'testing...'; } and when I'm trying to access the /index.php/forum/topic/ uri it just prints out my index() function. Can any one point out what may cause the problem?

  • Why does the assignment operator return a value and not a reference?

    - by Nick Lowman
    I saw the example below explained on this site and thought both answers would be 20 and not the 10 that is returned. He wrote that both the comma and assignment returns a value, not a reference. I don't quite understand what that means. I understand it in relation to passing variables into functions or methods i.e primitive types are passed in by value and objects by reference but I'm not sure how it applies in this case. I also understand about context and the value of 'this' (after help from stackoverflow) but I thought in both cases I would still be invoking it as a method, foo.bar() which would mean foo is the context but it seems both result in a function call bar(). Why is that and what does it all mean? var x = 10; var foo = { x: 20, bar: function () {return this.x;} }; (foo.bar = foo.bar)();//returns 10 (foo.bar, foo.bar)();//returns 10

  • What's wrong with this Perl 'grep' syntax?

    - by wes
    I've got a data structure that is a hash that contains an array of hashes. I'd like to reach in there and pull out the first hash that matches a value I'm looking for. I tried this: my $result = shift grep {$_->{name} eq 'foo'} @{$hash_ref->{list}}; But that gives me this error: Type of arg 1 to shift must be array (not grep iterator). I've re-read the perldoc for grep and I think what I'm doing makes sense. grep returns a list, right? Is it in the wrong context? I'll use a temporary variable for now, but I'd like to figure out why this doesn't work.
