  • Hiredis waiting for message

    - by Vivek Goel
    I am using hiredis C library to connect to redis server. I am not able to figure out how to wait for new messages after subscribing to new message. My code look like: signal(SIGPIPE, SIG_IGN ); struct event_base *base = event_base_new(); redisAsyncContext *c = redisAsyncConnect("127.0.0.1", 6379); if (c->err) { /* Let *c leak for now... */ printf("Error: %s\n", c->errstr); return 1; } redisLibeventAttach(c, base); redisAsyncSetConnectCallback(c, connectCallback); redisAsyncSetDisconnectCallback(c, disconnectCallback); redisAsyncCommand(c, NULL, NULL, "SET key %b", argv[argc - 1], strlen(argv[argc - 1])); redisAsyncCommand(c, getCallback, (char*) "end-1", "GET key"); redisAsyncCommand(c, getCallback, (char*) "end-1", "SUBSCRIBE foo"); Now how to tell hiredis to wait for message on channel ?

  • How can I execute a bunch of editor commands stored in a file in VIM?

    - by LES2
    I have read the other posts, e.g., http://stackoverflow.com/questions/1830886/vim-executing-a-list-of-editor-commands and others. The answer isn't clear to me for my case. I have some editor commands that I generated from an SQL query. It uses :s/foo/bar to change country codes (from FIPS to a non-standard code set). Here's a sample of the file: :s/CB/CAMBO :s/CQ/NMARI :s/KV/KOSOV :s/PP/PAPUA ... I have saved that in a file called fipsToNonStd.vim (unsure about the correct extension). I want to run those commands one after another. What's the easiest way to do so? Thanks a bunch! SO Rocks!

  • GEvent.addListener(...) return?

    - by user354436
    Hello, my Question is as follows: What does GEvent.addListener(map, "click" function(){...}) return into the callback function? I don't find any information in the GMaps reference at all, can you show me some? The only thing I found out was that there are two parameters, "overlay" and "latLng" that are passed. The name of these parameters should not be of interest right? I could also name them "foo" and "bar" as far as I know. But the parameter "overlay" seems to be empty anyway? Also I have problems passing these two parameters directly into a callback function I created myself which looks like that... GEvent.addListener(gmap, "click", generateMarker(overlay, latLng)); ... instead of writing the following, which actually works fine. GEvent.addListener(gmap, "click", function(overlay, latLng) { generateMarker(overlay, latLng); });

  • How do I sum values from two dictionaries in C#?

    - by George Stocker
    I have two dictionaries with the same structure: Dictionary<string, int> foo = new Dictionary<string, int>() { {"Table", 5 }, {"Chair", 3 }, {"Couch", 1 } }; Dictionary<string, int> bar = new Dictionary<string, int>() { {"Table", 4 }, {"Chair", 7 }, {"Couch", 8 } }; I'd like to sum the values of the dictionaries together and return a third dictionaries with the keys, and the total values for each key: Table, 9 Chair, 10 Couch, 9 My current solution is to loop through the dictionary and pull them out that way, but I know that solution isn't the most performant or most readable. However, I'm hitting a brick wall trying to come up with a solution in LINQ.

  • How to select a MenuItem programatically

    - by Shaung
    I am trying to add a global shortcut to a gtk.MenuItem which has a sub menu. Here is my code: import pygtk, gtk import keybinder dlg = gtk.Dialog('menu test') dlg.set_size_request(200, 40) menubar = gtk.MenuBar() menubar.show() menuitem = gtk.MenuItem('foo') menuitem.show() menubar.append(menuitem) mitem = gtk.MenuItem('bar') mitem.show() menu = gtk.Menu() menu.add(mitem) menu.show() menuitem.set_submenu(menu) def show_menu_cb(): menubar.select_item(menuitem) keybinder.bind('<Super>i', show_menu_cb) dlg.vbox.pack_start(menubar) dlg.show() dlg.run() When I press the key menu pops up, I can then select items in the sub menu or press Esc to make it disappear. But after that the menuitem keeps selected and other windows never get input focus again. I have to click on the menuitem twice to get everything back normal.

  • How to iterate over every property of an object in javascript?

    - by OverloadUT
    Is there a way to iterate over every property of an object using the Prototype JavaScript framework? Here's the situation: I am getting an AJAX response in JSON that looks something like this: {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}} If I evaluate that json response in to a variable response, I want to be able to iterate over each property in the response.barobj object to see which indexes are true and which are false. Prototype has both Object.keys() and Object.values() but oddly seems to not have a simple Object.each() function! I could take the results of Object.keys() and Object.values() and cross-reference the other as I iterate through one, but that is such a hack that I am sure there is a proper way to do it!

  • Don't Change URL in Browser When Clicking <asp:LinkButton>

    - by Corey Goldberg
    I have an ASP.NET page that uses a menu based on asp:LinkButton control in a Master page. When a user selects a menu item, an onclick handler calls a method in my C# code. The method it calls just does a Server.Transfer() to a new page. From what I have read, this is not supposed to change the URL displayed in the browser. The problem is it that the URL changes in the browser as the user navigates the menu to different pages. Here is an item in the menu: <asp:LinkButton id="foo" runat="server" onclick="changeToHelp"><span>Help</span> </asp:LinkButton> In my C# code, I handle the event with a method like: protected void changeToHelp(object sender, EventArgs e) { Server.Transfer("Help.aspx"); } Any ideas how I can navigate through the menu without the browser's URL bar changing?

  • Javascript function question

    - by Raj
    I searched but couldn't find an answer to this seemingly easy question, so... Suppose I have a loop in which I need to set callbacks. My callback function looks like this: function callback(var1) { // code } Now my loop is something like this: for( //condition) { var x = something_different_each_time; document.getElementById('foo').addEventListener('click', function() { callback(x); }, false); } Now it looks like even if the loop runs n times, the anonymous function is compiled only once -- and hence every invocation of callback is called with the same argument (even though x varies in the loop every time). I must be missing something here.. any help is greatly appreciated! :)

  • change the return of to_param by action? or, terribly broken edit action if perma-url is returned in

    - by Stacia
    I did some stuff to have to_param return a perma-url so I'd have seo friendly links. Upon creation and update it will generate and return the perma-url in a to_param method that I put in the model. However this causing me some grief in other areas. I have a form that looks like this: <% @apps.each do |app| %> <% fields_for "[id][]", app do |fields| %> .... this fails terribly since it tries to insert the perma-url in place of the id. If I could just restrict to_param by action, that could solve things. If I change app to app.id, that fails since I have stuff like this: fields.check_box :is_featured . I suppose I could get the app instance, but that feels hacky. Again please excuse my lack of rails-foo ;)

  • PHP validating integers

    - by Mikk
    Hi, I was wondering, what would be the best way to validate an integer. I'd like this to work with strings as well, so I could to something like (string)+00003 - (int)3 (valid) (string)-027 - (int)-27 (valid) (int)33 - (int)33 (valid) (string)'33a' - (FALSE) (invalid) That is what i've go so far: function parseInt($int){ //If $int already is integer, return it if(is_int($int)){return $int;} //If not, convert it to string $int=(string)$int; //If we have '+' or '-' at the beginning of the string, remove them $validate = ($int[0] === '-' || $int[0] === '+')?substr($int, 1):$int; //If $validate matches pattern 0-9 convert $int to integer and return it //otherwise return false return preg_match('/^[0-9]+$/', $validate)?(int)$int:FALSE; } As far as I tested, this function works, but it looks like a clumsy workaround. Is there any better way to write this kind of function. I've also tried filter_var($foo, FILTER_VALIDATE_INT); but it won't accept values like '0003', '-0' etc.

  • How can we block the user from unchecking a DataGridView checkbox?

    - by hawbsl
    We have a DataGridViewCheckBox column bound to a boolean property in our class. The property setter has some logic which says that under certain conditions a True flag cannot be changed, ie, it stays checked forever. This is on a per record basis. So the entire column can't be readonly, only certain rows. Pseudo code: Public Property Foo() As Boolean Get Return _Foo End Get Set(ByVal value As Boolean) If _Foo And Bar And value = False Then //do nothing, in this scenario once you're true, you stay true Else _Foo = value End If End Set End Property Databinding is handling all of this fine, except that the checkbox is visibly cleared when it's clicked. Then, of course, when the binding / setter is fired (as you move off that cell) it is restored to its checked status per the underlying logic. Ultimately it doesn't matter too much but it's a clumsy bit of UI. How can we intercept the user's click and keep it checked?

  • Printf is not printing anything to output? C++ SDL

    - by Qasim
    I am trying to use "printf" in my Visual C++ project however it is not working. Using Lazy Foo's tutorial, I set up SDL in my project, but when I play it, printf doesnt do anything. #include "SDL.h" #include <stdio.h> int main( int argc, char* args[] ) { printf("Testing"); return 0; } The output looks like this: The program '[4664] SDL Testing.exe: Native' has exited with code 0 (0x0). And that's about it. What could be wrong?

  • Are protected constructors considered good practice?

    - by Álvaro G. Vicario
    I'm writing some little helper classes to handle trees. Basically, I have a node and a special root node that represents the tree. I want to keep it generic and simple. This is part of the code: <?php class Tree extends TreeNode{ public function addById($node_id, $parent_id, $generic_content){ if( $parent = $this->findNodeById($parent_id) ){ $parent->addChildById($node_id, $generic_content); } } } class TreeNode{ public function __construct($node_id, $parent_id, $generic_content){ // ... } protected function addChildById($node_id, $generic_content){ $this->children[] = new TreeNode($this->node_id, $node_id, $generic_content); } } $Categories = new Tree; $Categories->addById(1, NULL, $foo); $Categories->addById(2, NULL, $bar); $Categories->addById(3, 1, $gee); ?> My questions: Is it sensible to force TreeNode instances to be created through TreeNode::addById()? If it's so, would it be good practise to declare TreeNode::__construct() as private/protected?

  • Developing a very nonstandard Drupal form

    - by monksp
    I'm creating a site for a local retail shop using Drupal. Everything's been going very smoothly up until this current bit. It's a comic shop, and I want to make a place where people can manage their own subscriptions. Since the number of different titles a customer subscribes to can vary pretty widely, I want a way to make a completely dynamic form, with people able to add as many new lines as they need and I'm really struggling with Drupal's documentation. Essentially, I'd like the final version of the page to look something like this: http://www.monksp.org/foo.html Anyone have any experience building a drupal form like this?

  • PHPUnit doesn't recognize file_exists()

    - by Ondrej Slinták
    I've set up a project with unit test files in NetBeans. I set bootstrap to C:\www\foo\_tests\TestAutoload.php and put simple autoload method to this file: function __autoload( $class_name ) { // series of ifs if ( ... ) { $file_name = ... } if ( file_exists ( $file_name ) ) { require_once( $file_name ); } else { echo "autoload error"; } } All of my tests fail on autoload this way. They always output just "autoload error". If I don't check if file_exists and just use require_once( $file ) no matter what's in $file, it works perfectly. Anyone encountered anything like this before? It's not something I couldn't resolve by simply not checking whether file exists or not, but I'm interested why it does this and if I can cheat it somehow.

What's the best way to implement this and what kind of tools should I use. Sorry I am totally new in this area.

  • ASP .NET - What's going on behind an Eval() ?

    - by Amokrane
    Hi, I'm trying to understand how Eval() works for a specific purpose. I'm working on a project I don't really know and I need to read some data and put them in drop down list. These data are already read and are displayed inside an ItemTemplate. I noticed there are read using the Eval() method. Something like: <ItemTemplate> <a href="...=<%# Eval("foo") %>></a> </ItemTemplate> I need to know where Eval is getting these data from in order to discover where I should read them for my drop down list! But I didn't really understand how it works! I know that Eval() evaluates data binding expressions at runtime but where do you think I should take a look at? Thank you

  • simple form validation in dancer/perl

    - by devnull
    I am trying to do a simple form validation in perl dancer but I was wondering what would be the best way to validate simple parameters (e.g. field cannot be empty, validity of the email, minimum length of a field) in dancer/perl without any extra plugin or CPAN module here is the code so far post '/register' => sub { my $db = connect_db(); my $sql = 'insert into users (username, email, password, motivation) values (?, ?, ? ,?)'; my $sth = $db->prepare($sql) or die $db->errstr; $sth->execute(params->{'username'}, params->{'email'},params->{'password'}, params->{'motivation'}) or die $sth->errstr; set_flash('Hey you signed up !'); redirect '/thanks'; }; I did google it and I found several ways to do validation using CPAN modules like Form::Foo but how do it without that ?

  • Codesample with bufferoverflow (gets method). Why does it not behave as expected?

    - by citronas
    This an extract from an c program that should demonstrate a bufferoverflow. void foo() { char arr[8]; printf(" enter bla bla bla"); gets(arr); printf(" you entered %s\n", arr); } The question was "How many input chars can a user maximal enter without a creating a buffer overflow" My initial answer was 8, because the char-array is 8 bytes long. Although I was pretty certain my answer was correct, I tried a higher amount of chars, and found that the limit of chars that I can enter, before I get a segmentation fault is 11. (Im running this on A VirtualBox Ubuntu) So my question is: Why is it possible to enter 11 chars into that 8 byte array?

  • Sad logic on types

    - by user2972231
    Code base is littered with code like this: BaseRecord record = // some BaseRecord switch(record.source()) { case FOO: return process((FooRecord)record); case BAR: return process((BarRecord)record); case QUUX: return process((QuuxRecord)record); . . // ~25 more cases . } and then private SomeClass process(BarRecord record) { } private SomeClass process(FooRecord record) { } private SomeClass process(QuuxRecord record) { } It makes me terribly sad. Then, every time a new class is derived from BaseRecord, we have to chase all over our code base updating these case statements and adding new process methods. This kind of logic is repeated everywhere, I think too many to add a method for each and override in the classes. How can I improve this?

  • Java Webservice with generic methods

    - by danby
    Hi, I was wondering if it is possible to make a generic webservice method in java like this: @WebMethod public <T extends Foo> void testGeneric(T data){ However when I try to consume this with a Java client I get an error stating: [ERROR] Schema descriptor {http://####/}testGeneric in message part "parameters" is not defined and could not be bound to Java. I know it is possible to make a method that takes a parameter such as List and this generates correctly using JAX-WS. I don't mind if there is a solution that means I am tied to using only a particular technology. Thanks, Dan.

  • Optional parameters for interfaces

    - by bryanjonker
    Using c# 4.0 -- building an interface and a class that implements the interface. I want to declare an optional parameter in the interface and have it be reflected in the class. So, I have the following: public interface IFoo { void Bar(int i, int j=0); } public class Foo { void Bar(int i, int j=0) { // do stuff } } This compiles, but it doesn't look right. The interface needs to have the optional parameters, because otherwise it doesn't reflect correctly in the interface method signature. Should I skip the optional parameter and just use a nullable type? Or will this work as intended with no side effects or consequences?
