  • ASIHTTPRequest wrapper usage for Macs

    - by Rob
    I am trying to apply the ASIHTTPRequest wrapper to a very basic Objective C program. I have already copied over the necessary files into my program and after giving myself an extreme headache trying to figure out how it works through their website I thought I would post a question on here. The files copied over were: ASIHTTPRequestConfig.h ASIHTTPRequestDelegate.h ASIProgressDelegate.h ASIInputStream.h ASIInputStream.m ASIHTTPRequest.h ASIHTTPRequest.m ASIFormDataRequest.h ASIFormDataRequest.m My program is very basic: #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; // Defining the various variables. char firstName[20]; char lastName[20]; char rank[5]; int leaveAccrued; int leaveRequested; // User Input. NSLog (@"Please input First Name:"); scanf("%s", &firstName); NSLog (@"Please input Last Name:"); scanf("%s", &lastName); NSLog (@"Please input Rank:"); scanf("%s", &rank); NSLog (@"Please input the number leave days you have accrued:"); scanf("%i", &leaveAccrued); NSLog (@"Please input the number of leave days you are requesting:"); scanf("%i", &leaveRequested); // Print results. NSLog (@"Name: %s %s", firstName, lastName); NSLog (@"Rank: %s", rank); NSLog (@"Leave Accrued: %i", leaveAccrued); NSLog (@"Leave Requested: %i", leaveRequested); [pool drain]; return 0; } How do I utilize the wrapper to export these 5 basic variables to a web server via an http request?

  • Can PHP dissect its own syntax?

    - by Nathan Long
    Can PHP dissect its own syntax? For example, I'd like to write a function that takes in an input like $object->attribute and says to itself: OK, he's giving me $foo->bar, which means he must think that $foo is an object that has a property called bar. Before I try accessing bar and potentially get a 'Trying to get property of non-object' error, let me check whether $foo is even an object. The end goal is to echo a value if it is set, and fail silently if not. I want to avoid repetition like this: <input value="<? if(is_object($foo) && is_set($foo->bar)){ echo $foo->bar; }?> "/> ...and to avoid writing a function that does the above, but has to have the object and attribute passed in separately, like this: <input value="<? echoAttribute($foo,'bar') ?>" /> ...but to instead write something which: preserves the object-attribute syntax is flexible: can also handle array keys or regular variables Like this: <input value="<? echoIfSet($foo->bar); ?> /> <input value="<? echoIfSet($baz['buzz']); ?> /> <input value="<? echoIfSet($moo); ?> /> But this all depends on PHP being able to tell me "what kind of thing am I asking for when I say $object->attribute or $array[$key]", so that my function can handle each according to its own type. Is this possible?

  • Use of 'this keyword' javascript in IE ?

    - by Ron
    Is there a workaround for Internet Explorer to implement the functionality offered by 'this' javascript keyword to get the dom element that triggered the event? My problem scenario is : I have a variable number of text fields in the html form, like input type="text" id="11" input type="text" id="12" .. I need to handle the "onchange" event for each text field, and the handling is dependent on the 'id' of the field that triggered the event. So far I understand that my options are: 1) attach a dedicated event handler for each text field. so if I have n fields, i have n different functions, something like: input type="text" id="11" onchange="function11();" input type="text" id="12" onchange="function12();" but the text fields are added and removed dynamically, so a better way would be to have one generic function instead. 2) use the 'this' keyword like: input type="text" id="11" onchange="functionGeneric(this);" input type="text" id="12" onchange="functionGeneric(this);" But this option does not work with Internet Explorer. Can anyone suggest a work around for getting it work in IE or some other solution that can be applied here? Thanks.

  • PHP, MySQL: mysql substitute for php in_array function

    - by Devner
    Hi all, Say if I have an array and I want to check if an element is a part of that array, I can go ahead and use in_array( needle, haystack ) to determine the results. I am trying to see the PHP equivalent of this for my purpose. Now you might have an instant answer for me and you might be tempted to say "Use IN". Yes, I can use IN, but that's not fetching the desired results. Let me explain with an example: I have a column called "pets" in DB table. For a record, it has a value: Cat, dog, Camel (Yes, the column data is a comma separated value). Consider that this row has an id of 1. Now I have a form where I can enter the value in the form input and use that value check against the value in the DB. So say I enter the following comma separated value in the form input: CAT, camel (yes, CAT is uppercase & intentional as some users tend to enter it that way). Now when I enter the above info in the form input and submit, I can collect the POST'ed info and use the following query: $search = $_POST['pets']; $sql = "SELECT id FROM table WHERE pets IN ('$search') "; The above query is not fetching me the row that already exists in the DB (remember the record which has Cat, dog, Camel as the value for the pets column?). I am trying to get the records to act as a superset and the values from the form input as subsets. So in this case I am expecting the id value to show up as the values exist in the column, but this is not happending. Now say if I enter just CAT as the form input and perform the search, it should show me the ID 1 row. Now say if I enter just camel, cAT as the form input and perform the search, it should show me the ID 1 row. How can I achieve the above? Thank you.

  • Using JQuery with dynamically added controls (MVC)

    - by Mario
    I have a set of radio buttons that are dynamically generated (via JSON call): StringBuilder sbEligAll = new StringBuilder(); sbEligAll.Append("<div id='currentselectiondepartment'>"); sbEligAll.Append(" <input type='radio' name='selectalldepartment' id='radCurrent' value='0' /><label for='radCurrent'>Current</label>"); sbEligAll.Append(" <input type='radio' name='selectalldepartment' id='radFuture' value='1' /><label for='radFuture'>Future</label>"); sbEligAll.Append(" <input type='radio' name='selectalldepartment' id='radCurrentAll' value='2' /><label for='radCurrentAll'>Current All</label>"); sbEligAll.Append(" <input type='radio' name='selectalldepartment' id='radFutureAll' value='3' /><label for='radFutureAll'>Future All</label>"); sbEligAll.Append("</div>"); Then: return Json(new { TableList = sbElig.ToString() }, JsonRequestBehavior.AllowGet); Is there a way to get jQuery to be able to interact with these? For example: $("input[name=selectalldepartment]").change(function() { var str = $('input[name=selectalldepartment]:checked').val(); $(".radiolist[value='" + str + "']").attr("checked", true); }); I've tried everything I know how to do, but the jQuery just doesnt fire. (I've added alerts to the jQuery code to see if it actually gets called, and it does not). Any thoughts?! Thanks!

  • JavaScript Exception/Error Handling Not Working

    - by Seán Hayes
    This might be a little hard to follow. I've got a function inside an object: f_openFRHandler: function(input) { console.debug('f_openFRHandler'); try{ //throw 'foo'; DragDrop.FileChanged(input); //foxyface.window.close(); } catch(e){ console.error(e); jQuery('#foxyface_open_errors').append('<div>Max local storage limit reached, unable to store new images in your browser. Please remove some images and try again.</div>'); } }, inside the try block it calls: this.FileChanged = function(input) { // FileUploadManager.addFileInput(input); console.debug(input); var files = input.files; for (var i = 0; i < files.length; i++) { var file = files[i]; if (!file.type.match(/image.*/)) continue; var reader = new FileReader(); reader.onload = (function(f, isLast) { return function(e) { if (files.length == 1) { LocalStorageManager.addImage(f.name, e.target.result, false, true); LocalStorageManager.loadCurrentImage(); //foxyface.window.close(); } else { FileUploadManager.addFileData(f, e.target.result); // add multiple files to list if (isLast) setTimeout(function() { LocalStorageManager.loadCurrentImage() },100); } }; })(file, i == files.length - 1); reader.readAsDataURL(file); } return true; LocalStorageManager.addImage calls: this.setItem = function(data){ localStorage.setItem('ImageStore', $.json_encode(data)); } localStorage.setItem throws an error if too much local storage has been used. I want to catch that error in f_openFRHandler (first code sample), but it's being sent to the error console instead of the catch block. I tried the following code in my Firebug console to make sure I'm not crazy and it works as expected despite many levels of function nesting: try{ (function(){ (function(){ throw 'foo' })() })() } catch(e){ console.debug(e) } Any ideas?

  • Pass checkbox values with Jquery to PHP and display result in div

    - by user1343955
    I want to filter realtime results with jQuery (just like on this site http://shop.www.hi.nl/hi/mcsmambo.p?M5NextUrl=RSRCH). So when someones checks a checkbox the results should update realtime (in a div). Now I'm a newbie with jQuery and I've tried lots of examples but I can't get it to work. Here's my code, could anyone tell what I'm doing wrong? Thank you very much! HTML <div id="c_b"> Kleur:<br /> <input type="checkbox" name="kleur[1]" value="Blauw"> Blauw <br /> <input type="checkbox" name="kleur[2]" value="Wit"> Wit <br /> <input type="checkbox" name="kleur[3]" value="Zwart"> Zwart <br /> <br /> Operating System:<br /> <input type="checkbox" name="os[1]" value="Android"> Android <br /> <input type="checkbox" name="os[2]" value="Apple iOS"> Apple iOS <br /> </div> <div id="myResponse">Here should be the result</div> jQuery function updateTextArea() { var allVals = []; $('#c_b :checked').each(function() { allVals.push($(this).val()); }); var dataString = $(allVals).serialize(); $.ajax({ type:'POST', url:'/wp-content/themes/u-design/filteropties.php', data: dataString, success: function(data){ $('#myResponse').html(data); } }); } $(document).ready(function() { $('#c_b input').click(updateTextArea); updateTextArea(); }); PHP //Just to see if the var passing works echo var_export($_POST);

  • Get table row based on radio button using prototype/javascript

    - by David Buckley
    I have an html table that has a name and a radio button like so: <table id="cars"> <thead> <tr> <th>Car Name</th> <th></th> </tr> </thead> <tbody> <tr> <td class="car">Ford Focus</td> <td><input type="radio" id="selectedCar" name="selectedCar" value="8398"></td> </tr> <tr> <td class="car">Lincoln Navigator</td> <td><input type="radio" id="selectedCar" name="selectedCar" value="2994"></td> </tr> </tbody> </table> <input type="button" value="Select Car" onclick="selectCar()"></input> I want to be able to select a radio button, then click another button and get the value of the radio button (which is a unique ID) as well as the car name text (like Ford Focus). How should I code the selectCar method? I've tried a few things like: val1 = $('tr input[name=selectedCar]:checked').parent().find('#cars').html(); val1 = $("td input[name='selectedCar']:checked").parents().find('.cars').html(); val1 = $('selectedCar').checked; but I can't get the proper values. I'm using prototype, but the solution can be plain javascript as well.

  • git filter-branch chmod

    - by Evan Purkhiser
    I accidental had my umask set incorrectly for the past few months and somehow didn't notice. One of my git repositories has many files marked as executable that should be just 644. This repo has one main master branch, and about 4 private feature branches (that I keep rebased on top of the master). I've corrected the files in my master branch by running find -type f -exec chmod 644 {} \; and committing the changes. I then rebased my feature branches onto master. The problem is there are newly created files in the feature branches that are only in that branch, so they weren't corrected by my massive chmod commit. I didn't want to create a new commit for each feature branch that does the same thing as the commit I made on master. So I decided it would be best to go back through to each commit where a file was made and set the permissions. This is what I tried: git filter-branch -f --tree-filter 'chmod 644 `git show --diff-filter=ACR --pretty="format:" --name-only $GIT_COMMIT`; git add .' master.. It looked like this worked, but upon further inspection I noticed that the every commit after a commit containing a new file with the proper permissions of 644 would actually revert the change with something like: diff --git a b old mode 100644 new mode 100755 I can't for the life of me figure out why this is happening. I think I must be mis-understanding how git filter-branch works. My Solution I've managed to fix my problem using this command: git filter-branch -f --tree-filter 'FILES="$FILES "`git show --diff-filter=ACMR --pretty="format:" --name-only $GIT_COMMIT`; chmod 644 $FILES; true' development.. I keep adding onto the FILES variable to ensure that in each commit any file created at some point has the proper mode. However, I'm still not sure I really understand why git tracks the file mode for each commit. I had though that since I had fixed the mode of the file when it was first created that it would stay that mode unless one of my other commits explicit changed it to something else. That did not appear to the be the case. The reason I thought that this would work is from my understanding of rebase. If I go back to HEAD~5 and change a line of code, that change is propagated through, it doesn't just get changed back in HEAD~4.

  • Center aligned form with equal width labels

    - by James Goodwin
    I have a very simple web form which consists of labels and input fields, however I can not seem to find a way of aligning the form in the center of the page and for the labels to have an equal width so that they appear neatly next to each other, one under the other. The structure of my page is basically: <body> <div class="form"> <form method="post"> <fieldset> <label>Mobile:</label><input type="text" name="msisdn"><br/> <label>Code:</label><input type="text" name="code"><br/> <br/> <input type="image" src="submit-button.gif" alt="Submit"> <br/> <input type="checkbox" name="ts_and_cs"><label> Accept Terms and Conditions</label> <br/><br/> </fieldset> </form> </div> </body> Usually I would fix this by doing float:left on the label fields and setting a width on the labels, however for this I need the labels and input fields to be centered on the page. Also I am not able to set the width of the page (or any containing divs) as the page will be displayed on mobile devices with different screen sizes. Any suggestions as to how best style the form? Thanks

  • emacs -- keybind questions

    - by user565739
    I have successfully used Ctrl+Shift+Up ' Ctrl+Shift+down ' Ctrl+Shift+left' Ctrl+Shift+Right to different commands. But when I tried to use Ctrl+s to the command save-buffer and Ctrl+Shift+s, which is equivalent to Ctrl+S, to another command, it has some problem. save-buffer works fine, but when I type Ctrl+Shift+s, it excute the command save-buffer. I used Ctrl+q to find the control sequences of Ctrl+s and Ctrl+Shift+S, I get the same result, which is ^S. I expect that I will get ^s for Ctrl+s, but it doesn't. Anyone knows the reason? Another queston is: I use Ctrl+c for the command killing-ring-save. In this case, all commands (which are of large number) begin with Ctrl+c don't work now. Is there a way to replace the prefix Ctrl+c by another customized prefix? I may pose my question in the wrong direction. I use ctrl+c as killing-ring-save. It works fine in emacs (no mode). But if I open a .c file (C-mode), then when I type Ctrl+c, it waits me to type another key. I think in this case, ctrl+c is regarded as a prefix. In this case, I need the following modifications: Using a custom defined prefix, say Ctrl+a, as Ctrl+c ; Remove the prefix Ctrl+c ; Using Ctrl+c as killing-ring-save. I add the following to my ~/.emacs : (defun my-c-initialization-hook () (define-key c-mode-base-map (kbd "C-a") mode-specific-map) (define-key c-mode-base-map (kbd "C-c") 'kill-ring-save)) (add-hook 'c-initialization-hook 'my-c-initialization-hook) But this doesn't work. Ctrl+c is still regarded as a prefix, so I can't use it as kill-ring-save. Furthermore, if I type Ctrl+a Ctrl+c, it said it's not defined. (I thought it will have the same result as I type Ctrl+c Ctrl+c)

  • DLL response is to slow in Visual Studio

    - by magsto
    Hi, I use a 3rd party DLL in my VB.NET project (VS2005) that responds to slow and give wrong values in debug mode. In run-time mode everything works as expected. I do understand that there are something going on in the debug mode which makes the DLL communication slow. This behavior makes it hard to debug the application correctly. Is there any way to force VS to communicate with the DLL in "run-time" mode during debugging but let the rest of the project be in control of the debugger?

  • Jquery Basic Beginner Question: How do i make my function reusable?

    - by obikodi
    I have spent the last few hours attempting to do this on my own, and using Google to find a solution but to no avail. So if you can help out i would super appreciate it! Basically I have a page which has 3 separate biographies in 'preview mode', which shows only the first paragraph of each bio. When you click on 'read more' for one bio it opens up the 'full mode'. What is happening at the moment, is if i click on one 'read more' link, it opens up the full mode on all 3 bio's. How do i edit the following code so; It only opens the full mode bio of the link i click on Make it reusable so i don't have to duplicate the code 3 times for each bio $("a#btnReadMore").click(function(){ $('.readMoreSlider').slideToggle("fast"); $(this).toggleClass("readMoreSliderActive"); return false; }); Thanks for your help!

  • Visual Studio detaches from application as soon as debugging starts

    - by rwmnau
    I have a web application that I've always been able to run in Visual Studio and it debugs just fine (breakpoints work, I can pause execution, etc). Recently, the behavior changed suddenly, and a few things happen: I start debugging, it lauches IE and loads the application, but after a few seconds (sometimes the page hasn't even displayed yet), Visual Studio acts as if debugging has stopped - I'm able to edit code in VS again, and the "Play" button on the toolbar is enabled. The application continues to run in the IE window just spawned, but I'm not attached to it During this few seconds that VS is "debugging", because it detaches, my breakpoints show as hollow - as if I'm set to "Release" mode and they won't be hit. In fact, I have a breakpoint set in Page_Load, and it skips right by. I've checked, and I'm set to debug mode, though the compile mode dropdown is missing from my toolbar (I checked in the build properties to ensure I was in debug mode). Can anybody shed some light here?

  • How should I progressively enhance this content with JavaScript?

    - by Sean Dunwoody
    The background to this problem is that I'm doing a computing project which involves Some drop down boxes for input, and a text input where the user can input a date. I've used YUI to enhance the form, so the calendar input uses the YUI calendar widget and the drop down list is converted into a horizontal list of inputs where the user only has to click once to select any input as opposed to two clicks with the drop down box (hope that makes sense, not sure how to explain it clearly) The problem is, that in the design section of my project I stated that I would follow the progressive enhancement principles. I am struggling however to ensure that users without JavaScript are able to view the drop down box / text input on said page. This is not because I do not necessarily know how, but the two methods I've tried seem unsatisfactory. Method 1 - I tried using YUI to hide the text box and drop down list, this seemed like the ideal solution however there was quite a noticeable lag when loading the page (especially for the first time), the text box and drop down list where visibile for at least a second. I included the script for this just before the end of the body tag, is there any way that I can run it onload with YUI? Would that help? Method 2 - Use the noscript tag . . . however I am loathed to do this as while it would be a simple solution, I have read various bad things about the noscript tag. Is there a way of making mehtod one work? Or is there a better way of doing this that I am yet to encounter?

  • python gui events out of order

    - by dave
    from Tkinter import * from tkMessageBox import * class Gui: def __init__(self, root): self.container = Frame(root) self.container.grid() self.inputText = Text(self.container, width=50, height=8) self.outputText = Text(self.container, width=50, height=8, bg='#E0E0E0', state=DISABLED) self.inputText.grid(row=0, column=0) self.outputText.grid(row=0, column=1) self.inputText.bind("<Key>", self.translate) def translate(self, event): input = self.inputText.get(0.0, END) output = self.outputText.get(0.0, END) self.outputText.config(state=NORMAL) self.outputText.delete(0.0, END) self.outputText.insert(INSERT, input) self.outputText.config(state=DISABLED) showinfo(message="Input: %s characters\nOutput: %s characters" % (len(input), len(input))) root = Tk() #toplevel object app = Gui(root) #call to the class where gui is defined root.mainloop() #enter event loop Working on a gui in tkinter I'm a little confused as to the sequence the event handlers are run. If you run the above code you'll hopefully see... 1) Editing the text widget triggers the event handler but it seems to fire it off without registering the actual change, 2) Even when the text widget is cleared (ie, keep pressing BackSpace) it still seems to have a one character length string, 3) The output widget only receives its update when the NEXT event trigger is fired despite the fact the data came on the previous event. Is this just how bindings work in tkinter or am i missing something here? The behaviour i would like when updating the input widget is: 1) Show the change, 2) Enter event handler, 3) Update output widget, 4) Show message box.
