• CFHTTP PUT without a physical file

  - by E-Madd

  I'm trying to communicate with an API that requires JSON payloads via PUT method. Is it possible to do this in CFHTTP with CFHTTPPARAM without first writing a file? My code currently looks like this... <cfset json = "{'key':'value'}"> <cffile action="write" file="#ExpandPath('./test.js')#" output="#json#" /> <cfhttp method="put" url="http://servicedomain.com/api/method/" resolveurl="no" username="username" password="password"> <cfhttpparam mimetype="application/json" type="file" name="payload" file="#ExpandPath('./test.js')#" /> </cfhttp>

• PHP, what is the better choice for removing a known string?

  - by Brook Julias

  I am looking to search for and replace a known string from within another string. Should I use str_replace() or ereg_replace()? The string to be replaced would be something similar to [+qStr+], [+bqID+], or [+aID+] and it would be being searched for in a code chunk similar to this: <li> [+qStr+] <ol class="mcAlpha"> <li><input type="radio" name="[+bqID+]" id="[+bqID+]_[+aID+]" value="[+aID+]" /><label for="[+bqID+]_[+aID+]">[+aStr+]</label></li> </ol> </li> I would be replacing the strings with the results from a MySQL query, and be performing this action or similar up to 200 times at a time. Which function str_replace() or ereg_replace() would be the easiest and/or quickest method to take.

• How can I login in a website with Pyhon?

  - by Shady

  How can I do it? I was trying to enter some specified link (with urllib), but to do it, I need to log. I have this source from the site <form id="login-form" action="auth/login" method="post"> <div> <!--label for="rememberme">Remember me</label><input type="checkbox" class="remember" checked="checked" name="remember me" /--> <label for="email" id="email-label" class="no-js">Email</label> <input id="email-email" type="text" name="handle" value="" autocomplete="off" /> <label for="combination" id="combo-label" class="no-js">Combination</label> <input id="password-clear" type="text" value="Combination" autocomplete="off" /> <input id="password-password" type="password" name="password" value="" autocomplete="off" /> <input id="sumbitLogin" class="signin" type="submit" value="Sign In" /> It's possible?

• display a confirmation popup on button click based on condition

  - by Raaz

  I have a p:commandButton on click of which I need to add a few values to a list. In my managed bean, I'm validating the value that has to be added, and if it validates to false, I have to display a confirmation popup. This is my code - <p:commandButton id="add" value="Add" type="submit" action="#{bean.doAdd}" ajax="false" update=":List"/> And in the bean, on click of the "Add" button, public String doAdd() throws Exception { if(response != null) { if(keyList.contains(response)) { if(!responseList.contains(response)) { responseList.add(response); } } else { //Have to display confirmation popup. } response = ""; } return response; } I'm using jsf 2.0 and primefaces 3.0. Can someone please tell me how to display the popup from the bean?

• Javascript code for handling Form behaviour.

  - by Andrew

  Hello, Here's how the situation looks : I have a couple simple forms <form action='settings.php' method='post'> <input type='hidden' name='setting' value='value1'> <input type='submit' value='Value1'> </form> Other small forms close to it have value2, value3, ... for the specific setting1, etc. Now, I have all these forms placed on the settings.php subpage, but I'd also like to have copies of one or two of them on the index.php subpage (for ease of access, as they are in certain situations rather frequently used). Thing is I do not want those forms based on the index.php to redirect me in any way to settings.php, just post the hidden value to alter settings and that's all. How can I do this with JS ? Cheers

• Double-tap or two single-taps?

  - by Jaka Jancar

  What is the time limit for two taps to be considered a double-tap, on the iPhone OS? // Edit: Why is this important? In order to handle single-tap and double-tap differently, Apple's guide says to do performSelector...afterDelay with some 'reasonable' interval on first tap (and cancel it later if the second tap is detected). The problem is that if the interval is too short (0.1), the single tap action will be performed even when double-tapping (if relying only on tapCount, that is). If it's too long (0.8), the user will be waiting unnecessarily for the single-tap to be recognized, when there is no possibility for a double-tap. It has to be exactly the correct number, in order to work optimally, but definitely not smaller, or there's a chance for bugs (simultaneous single-tap and double-tap).

• why doesn't hitting enter when a SELECT is focused submit the form?

  - by Marc

  Consider the following HTML: <form action=""> <input /> <select> <option>A</option> <option>B</option> </select> <input type="submit" /> </form> If the focus is on the input (text box) and I hit enter, the form submits. But, if the focus is on the select (dropdown box) and I hit enter, nothing happens. I know I could figure out some JavaScript to override this, but I want to know why hitting enter doesn't just work? Is there something I would break by capturing the enter with JavaScript (maybe some native keyboard accessibility of the dropdown)?

• posmax: like argmax but gives the position(s) of the element x for which f[x] is maximal

  - by dreeves

  Mathematica has a built-in function ArgMax for functions over infinite domains, based on the standard mathematical definition. The analog for finite domains is a handy utility function. Given a function and a list (call it the domain of the function), return the element(s) of the list that maximize the function. Here's an example of finite argmax in action: http://stackoverflow.com/questions/471029/canonicalize-nfl-team-names/472213#472213 And here's my implementation of it (along with argmin for good measure): (* argmax[f, domain] returns the element of domain for which f of that element is maximal -- breaks ties in favor of first occurrence. *) SetAttributes[{argmax, argmin}, HoldFirst]; argmax[f_, dom_List] := Fold[If[f[#1]>=f[#2], #1, #2]&, First[dom], Rest[dom]] argmin[f_, dom_List] := argmax[-f[#]&, dom] First, is that the most efficient way to implement argmax? What if you want the list of all maximal elements instead of just the first one? Second, how about the related function posmax that, instead of returning the maximal element(s), returns the position(s) of the maximal elements?

• Is it actually possible to connect to ActiveMQ via XMPP and query/browse queues using "AciveMQ.Agen

  - by Oleg Kiorsak

  I tried what I think are 4 most popular XMPP (aka "Jabber") clients (Spark, Pidgin, Psi, Pandion) to connect to ActiveMQ instance (Apache ActiveMQ ver. 5.3.0) on XMMP connector with an idea to use the "AciveMQ.Agent chatroom" for querying queues/etc and no success at all Some of them fail with 'Unknown error', some don't fail but kind of "hang"... interestingly, some communication does indeed reach the ActiveMQ side, because when I close a client it spits an exception "could not close" or something to that effect... and if I try "register new user" option (present on most clients" the ActiveMQ also spits some most cryptic warning message But I was never able to get to the point when I could see or specify "ActiveMQ.Agent" as chatroom and issue any commands... Before I waste any more time on this curious feature, I would like to hear whether anyone had any success with it? Thank you! PS: BTW, the book "ActiveMQ in Action book" http://www.manning.com/snyder/ shows that it is apparently works and is very easy using some Mac client (AdiumX), but I wanted it on a Windows PC ;)

• Getting MVC default route to go to ~/default.asp

  - by Dave Hanna

  I am adding some MVC features to an existing site (FWIW, most of which is in classic ASP). As a result, I need to keep the default routing going to ~/default.asp (at a minimum - preferably the default document specified in IIS). Is there a way to write the route in RegisterRoutes so that a request for the root of the site (e.g., http://localhost, http://localhost/, or http://localhost/default.asp) will directly get the default page, and not attempt to find a controller/action? Or do I need to write my own HttpModule that will filter it and keep it from getting to the MvcHandler (as in this blog)? BTW, I have googled this, but most of the hits are for MVC version 1 or older, and default routing appears to have changed in version 2 (i.e, there is no more default.aspx that redirects to ~/Home), so they are not directly applicable. Even so, the ones that were there didn't address this problem.

• How to detect when UITextField become empty

  - by Jakub

  Hello, I would like to perform a certain action when UITextField becomes empty (user deletes everything one sign after another or uses the clear option). I thought about using two methods - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string; and - (BOOL)textFieldShouldClear:(UITextField *)textField; from UITextFieldDelegate I'm not sure how to detect the situation when the text field becomes empty? I tried with: if ([textField.text length] == 0) but it does't work as the fisrt of the above methods is called before the sign is deleted from the text field. Any ideas?

• How does Rails find models and controllers? How can I get it to load more models?

  - by David

  I'm trying to create a non-ActiveRecord model in app/models/gamestate.rb. Then inside my controller (PlayController) I should be able to do GameState.new, right? No go: NameError (uninitialized constant PlayController::GameState): app/controllers/play_controller.rb:23:in `play' (at least in the development environment) But! If I do have a model called app/models/play.rb, then it's automatically loaded and I can do Play.new. So my question is: how does Rails know which classes to load? What sort of name mangling does it do to get from play#action to PlayController to app/controllers/play_controller.rb to app/models/play.rb? It seems awfully fragile, but maybe a better understanding of how this works would help. And finally, how can I get it to load app/models/gamestate.rb?

• Mouse Capture and Selection

  - by Tommy

  I have a control, that moves around alot of different controls inside of it in the form of a grid. So basically, none of the container control is shown at any point. But i do have capture of all the mousedown and mousemove events of the controls inside. What id like to do, is create an effect alot like the desktop of a windows computer, where you can drag, and every control that is inside of the mouse's drag will be thrown in a list, and when the mouse is released i can perform an action on all the selected items. Is this possible?

• ASP.NET MVC - How to save some data between requests ?

  - by Tony

  Hi, I'm trying to solve the problem: when a user is being logged into a WebSite (via user control .ascx stored on the Master Page), it's name is being stored in a Page.User.Identity.Name property. OK, but how to retrieve that user name in the controller ? Is it possible without registering System.Security.Principal namespace in the controller ? In the other words - the controller must know whose user wants to do some action (e.g. change account data). I could store it's name in the Html.Hidden control on each View but I don't want to have a mess in my Views

• Does Displaytag stash the "media type" in a page or request attribute?

  - by Pointy

  When you enable "export" from Displaytag, the tag code gives you links with special magic parameters that the tag recognizes as indicators that the table contents should be exported (as CSV, Excel, whatever). Well I'm interested in detecting the media type so that (for example) I can exclude columns that make no sense in an export (embedded action buttons, for one thing, or checkboxes for row selection). I suppose I could write a table decorator and use that to stick the media type on the request, but it'd be nice to avoid that if the tag already does it. The documentation is not clear on the subject; I guess I can start digging through the source code too.

• Enumerating all combinations of lists of different types

  - by jball

  Given two IEnumberables of different types, what is the best practice (considering readability and maintainability) for iterating over both lists to perform an action on all possible combinations? My initial solution was to use nested foreach loops, iterating over the first IEnumerable, and then within that loop, iterating over the second IEnumerable and passing the value from the outer and the current loop into the target method. Eg.: enum ParamOne { First, Second, Etc } List<int> paramTwo = new List<int>() { 1, 2, 3 }; void LoopExample() { foreach (ParamOne alpha in Enum.GetValues(typeof(ParamOne))) { foreach (int beta in paramTwo) { DoSomething(alpha, beta); } } } I tried to restructure it with LINQ, but ended up with something that had no obvious advantages and seemed less intuitive. A search here shows lots of questions about nesting foreachs to iterate over child properties, but I couldn't find anything about iterating over two distinct lists.

• Php file outputting javascript for include as a JS file - need to restrict so its not opened in a browser window

  - by Ali

  Hi guys, I'm storing configuration details in a database which I need to use in javascript. I'm accessing all this using php and instead of outputting all the details into inline javascript code on the main page I've instead created a php file that outputs content type javascript and refernce it in my main page as an external javascript file. I want to set it up so that it can't be viewed in a browser window i.e : <script type="text/javascript" src="phpFileThatDoesJS.php" ></script> should work but typing www.mysite.com/phpFileThatDoesJS.php in the browser shouldn't EDIT ========== The thing is that I have to edit a script that for some oddball reason stores the username and password of a user in a javascript Object and outputs it within script tags. I have to set it up so that this is not viewable by a simple view source action. Thats why I thought of referencing it as an external javascript. Isnt there any htaccess tricks that I could use?

• immediate=true is set on a jsf command button but still seeing validation

  - by Zack Macomber

  I have the following command button set up in a facelet: <h:commandButton action="#{addressAction.deletePreviousAddress}" value="#{bundle['button.deleteAddress']}" styleClass="deg-form-button" immediate="true"> <f:setPropertyActionListener target="#{addressAction.addressActionForm.previousAddress}" value="#{address}"> </f:setPropertyActionListener> </h:commandButton> In AddressAction, the following code gets run to delete a previous address on the form: public Enum<NavigationConstants> deletePreviousAddress() { addressActionForm.getPreviousAddresses().remove(addressActionForm.getPreviousAddress()); return NavigationConstants.addresses; } Before I made the address input components "required=true", this code worked fine and removed the previous address from the jsf form successfully. Right now, I can't successfully delete a previous address because validation is occurring and stating that the input components need to be filled in on the previous address record on the form. How can I bypass this validation? I thought the "immediate=true" attribute on the command button would have accomplished it but that's not cutting it in my case...

• At what level should security be implemented in a social network web application ?

  - by Rajkumar Gupta

  I am developing a social web application in php/mysql, I would like to hear your advice about what would be a better way to implement security. I am planning something like this:- At the presentation level, I restricting the user to see only those items/content he is eligible to see with the rights he is eligible & at the database level, whenever my data is read/ written or updated I verify that the person has rights to such interactions with that part of data. So for each action there is 2 layers of security one at the view level & another at the database level. Would double checking be much overhead ? ofcourse this handles only with the internal security issues ..

• FOSUserBundle: embedding the login form and choosing its template

  - by tirengarfio

  i want to insert the login form of FOSUserBundle in my template like this: <div id="sidebar"> {% render "FOSUserBundle::Security::login" %} </div> but not to render the template that is been calling in the code of loginAction() originally. I have thought I'd find useful the possibility of passing the template I want to render as a parameter as 'max' in this example: <div id="sidebar"> {% render "AcmeArticleBundle:Article:recentArticles" with {'max': 3} %} </div> Is that possible in symfony2? If not.. should I create another action for my bundle with the same code inside of loginAction? or should I modify the original loginAction code and write control structures? if(currentPage == 'home') renderResponse('template1') else renderResponse('template2')

It sets $msg to 'some error message' and $msgalert to 'error' in case of any error. At the end of processing it uses header() to redirect to index.php But after redirection $msg and $msgalert get out of scope and index only gets empty vars. How can i fix this?
