  • Using PHP's exec() function (or the likes), how can you display terminal error output?

    - by Miciah Amberong
    Previous Reference I am just wondering if there's a way (using PHP) to output the compile error information from the terminal to the browser? For example: If you use this code to execute in the terminal... gcc -o try try.c ...and assuming the "try.c" have some errors. The terminal will output something like this: try.c In function 'main': try.c:27 'x' undeclared (first use in this function) try.c:27 (Each undeclared identifier is reported only once try.c:27 for each function it appears in.) Meanwhile, using this PHP code... <?php exec("gcc -o try try.c"); ?> The browser does not return any output like the terminal does. Is there a possible way direct or indirect that the error details that the terminal showed can be passed to the be displayed on a browser? Thank you very much.

  • sorting extendeddatatable in richfaces

    - by user414597
    Hello All, does anyone know how exactly the default sorting works in richfaces datatable columns? (using sortby) My problem is that once a sort has been performed, the new data order is never preserved in my backing's bean data model (which makes me wonder where is this new order now stored?), that is the actual datamodel always contains just the original data.. So if say user goes to a another page and returns to what should be sorted data (using back button) , the data displays as original, not sorted.. Has anyone come across this? also, is there a way to do server side sorting, i.e. call my own sort method upon clicking the header..? many thanks for any advice!

  • C# ToolTip will not re-appear after first use.

    - by Roberto Sebestyen
    I have a Forms C# application where I would like to use a toolTip on one of the text boxes. I Initialize the tool-tip in the constructor of the Form class, and it works the first time. So when I hover over the text box with my mouse it works, but once the toolTip times out and it goes away, it does not re-appear when I move my mouse away and back onto the control. I would expect it to come back and I'm wondering what I'm doing wrong. Here is how I initialize the tooltip: myTip = new ToolTip(); myTip.ToolTipIcon = ToolTipIcon.Info; myTip.IsBalloon = true; myTip.ShowAlways = true; myTip.SetToolTip(txtMyTextBox,"My Tooltip Text");

  • Build common interface for two applications(one is in .asp, other in java)

    - by govardhan
    We have two applications. One application in .asp and second application in java. we want to build interface for universal authentication, so that one can access the other application once signed into one application. Both applications are using SQL database, but one is written in .ASP hosted on Windows server while the other is in JAVA hosted on a Linux server. The applications are currently resided on two different servers. requirements: 1)The end user are most likely to access the applications through .ASP first, then reach the 2nd application more like "back office" management system. 2)he JAVA application currently works well with IE web browser, but not very smooth with other browsers such as Firefox. Would like to make the application to be more compatible with other browsers. Please help me, its very important to me. Thanks in advance!

  • Creating a PHP web app to allow users to vote on submissions - How can I minimize abuse.

    - by sibliant
    Hi Community, I've only written a few small php web apps and I'm throwing code together right now to allow for users to submit short stories. these stories will display and allow others to vote them up. The winner receives something rather valuable and I'm paranoid people are going to try to manipulate it. Debian / Apache / PHP 5.2 / jquery users are not required to login / authenticate. users can vote multiple stories up but only once for each story Is it as simple as tagging each story with an IP address and not counting other submissions from that IP? Thanks for any advise.

  • JQuery Facebook like Tag feature

    - by Tech
    Hi, Does anyone know of a very basic tag JQuery script? (Facebook like tag feature) All I want to do is when I type @ in a text box for it to search an AJAX search, it then brings back a display name i.e. "Bob Johnson" and an associated Id and stores the Id in a comma delimited list. So an example would be the following .... [TextArea] [Name 1] [Name 2] [Name 3] The thing is it also needs to remove this entry (Id) once the tag gets removed, also it needs to load into a DIV which has a scrollbar so that the list doesn't get to big. If anyone know's how/if this is possible that would be great. Thanks.

  • Copy a value based on criteria Salesforce

    - by Robert
    Hi all, On a Salesforce.com opportunity I have a number of custom fields that are potential options that the end client will eventually select. Option 1 (Desc Field) Option 1 (Value) Option 2 (Desc Field) Option 2 (Value) Option 3 (Desc Field) Option 3 (Value) At a future point the user will ultimately choose one of the options as the preferred option. What I want is then the value for the chosen option to be stored in another field without the user having to enter it again. A “nice to have” would also be that all 3 option descriptions, values and selected value are locked once this is done. Any ideas?

  • Ruby on Rails: Modules vs. Classes

    - by Jack
    I'm trying to add a function that will be accessible throughout all parts of my program. I want something like: def GlobalFunctions.my_function(x,y) puts x + y end to be accessible for all models. Specifically I am trying to use a function like this in my seeds.rb file but I am most likely going to be reusing the code and don't want any redundancy. Now I know I can make a simple class, but I could also make a module. What are some reasons to go in either direction? And once I've decided on which type to use, how do I make it accessible throughout the whole program? I have tried a module, but I keep getting " Expected app/[module file] to define [ModuleName]"

  • ASP MVC Creating Form Rows Dynamically

    - by Jonathan Stowell
    Hi Guys, I haven't even attempted this yet and am creating this question for advice really. I have a strongly typed page which receives a form model composed of several components. It is to create a mitigating circumstance (MC) for a student at a university for my final year project. A MC can be composed of the initial problem, assessment extensions, and I use a multi select box to allow the user to select staff retrieved from the database which are able to view the MC once created. The thing is I feel that a student could be granted many assignment extensions for one problem. I am wander if it is possible to include a button/image on the form which when clicked will create a new assessment extension object, and duplicate the form components to set the values for the object? This would all need to occur without any page refreshes. Any advice, or links to good tutorials would be appreciated. I have so far been unable to find any suitable examples. Thanks, Jon

  • Programmatically Untag FB Photos with Javascript

    - by Tal
    Hello! I've spent the past hour hacking away at this: I want to write a Javscript routine to programatically untag myself from photos on Facebook. Once it works, I'll run it in the Firebug console and untag myself from all Facebook photos (there's no way to do this through the GUI). I wanted to see if you guys had some advice to get me on my journey. I have a few methods in mind but haven't come too far along quite yet. I've tried an AJAX approach by creating a new HTML request and pointing it to the remove_tag URL, which looks something like this: /ajax/photo_tagging_ajax.php?pid=(PICTURE_ID)&id=(PICTURE_OWNER_ID)&subject=(SOMETHING)&name=(YOUR+NAME)&action=remove Not surprisingly, this doesn't work (yet). I've been checking the HTTP response in Firebug and it's quite different than the one when I actually untag a picture. It's not even sending a POST request. Will this even be possible or am I dreaming? (it's almost 4AM)

  • Displaying conditional amount of fields in UI (Android)

    - by Sochin
    I am using layout xml documents for my ui controls. I need to create and remove these controls (input fields) on the fly, based on how many results I get back from my database. For each group, there can be 0..* fields and these are prepopulated from the database. Also, it would be good if I can invoke a method to create an additional field; something like the address book, where you can click + or - to add or remove a phone or other detail. In a "psuedo" style, I'm guessing something like this: Check database - How many of X are there [y]? Create Y fields. The user may then add new fields, so once I click submit i need to apply all of that to database. Any examples or hints greatly welcomed. Hope this make sense! :)

  • Explanation of NSMutableURLRequest : setHTTPMethod

    - by kkmoslehpour
    I am new to objective c programming. I am currently trying to insert data into mysql database. I have read a couple links on this and could not find the exact answer I am looking for. Here is what I am trying to do: I have my app that user inputs a name in a text field and once the press the add button, it makes a connection to my php file and my php file does the rest of the work (using POST method) and adds the name to the mysql dataase. I have seen a lot of people use NSMutableURLRequest : setHTTPMethod :POST`` in their code (in my case my php file does that and I don't haveNSMutableURLRequest` included in my code and it works perfectly fine.) My questions are: Are there any benefits of including NSMutableURLRequest in your code when you can just call your php code to take care of the POST for you? What does NSMutableURLRequest exactly do and which way is more efficient?

  • continously add picture to video

    - by m.sr
    Every x minutes I grab an image from a network-cam. Now i want to add this picture to an existing video file - on the fly. I don't want to keep numerous image files and then encode them once in a while with e.g. mencoder mf://@${LIST} -mf type=jpg:fps=${FPS} ... The video format/codec doesn't really matter, as long as standard tools (mplayer, ffmpeg, vlc, ...) can handle it. Any ides or suggestions? Thanks in advance!

  • JavaScript - Is it possible to get height from div in separate page?

    - by Kenny Bones
    Hi, I'm wondering, is it possible to collect the height of a specific div container from a separate page with JavaScript? I'm using jQuery btw and I'm in need of comparing heights of div containers. Edit: To clarify a bit more, I load content from a specific div in a separate page using jQuery. This content is faded into a different container with dynamic height. But in the small fraction of time before the content arrives, it shrinks down to it's min-height. What I've done so far is collecting the height of the container before and after the load. But it only works after I've loaded content once. Because I don't have the height before it's been loaded the first time.

  • Python Class Variables Question

    - by zyq524
    I have some doubt about python's class variables. As my understanding, if I define a class variable, which is declared outside the init() function, this variable will create only once as a static variable in C++. This seems right for some python types, for instance, dict and list type, but for those base type, e.g. int,float, is not the same. For example: class A: dict1={} list1=list() int1=3 def add_stuff(self, k, v): self.dict1[k]=v self.list1.append(k) self.int1=k def print_stuff(self): print self.dict1,self.list1,self.int1 a1 = A() a1.add_stuff(1, 2) a1.print_stuff() a2=A() a2.print_stuff() The output is: {1: 2} [1] 1 {1: 2} [1] 3 I understand the results of dict1 and list1, but why does int1 behavior different?

  • Randomly generating sequence of ints in a specific range

    - by vvv
    Hi, I am unsure how to put this and my math skills aren't that strong. But here's what I need. I want to generate a list of all the 16bit integers (0-65535). But everytime I do so I want to seed the algorithm randomly that each time the list starts with a different integer and all the subsequent integers will be generated once but also in random order. small example (1-5): ... 1, 5, 3, 2, 4 4, 3, 1, 5, 2 2, 1, 4, 5, 3 ... Any help?

  • Unit tests logged (or run) multiple times

    - by HeavyWave
    I have this simple test: protected readonly ILog logger = LogManager.GetLogger(MethodBase.GetCurrentMethod().ReflectedType); private static int count = 0; [Test] public void TestConfiguredSuccessfully() { logger.Debug("in test method" + count++); } log4net is set up like this: [TestFixtureSetUp] public void SetUp() { log4net.Config.BasicConfigurator.Configure(); } The problem is, that if I run this test in nUnit once, I get the output (as expected): 1742 [TestRunnerThread] DEBUG Tests.TestSomthing (null) - in test method0 But if I press RUN in nUnit.exe again (or more) I get the following: 1742 [TestRunnerThread] DEBUG Tests.TestSomthing (null) - in test method1 1742 [TestRunnerThread] DEBUG Tests.TestSomthing (null) - in test method1 And so on (if I run it 5 times, I'll get 5 repeating lines). Now, if I run the same test alone from reSharper the output is fine and does not repeat. However, if I run this test along side 2 other tests in the same class, the output is repeated three times. I am totally confused. What the hell is going on here?

  • Proper way to 100% wakes my device?

    - by quiel
    Do you have better way to make the device awakes by 100%? I repeatedly call the acquire() but I'm not sure if that is correct. Or should I just call the acquire() once? Or should I make use of Intent.ACTION_SCREEN_OFF? public class MyServiceThatKeepsTheDeviceAwake extends IntentService { ... @Override public void onCreate() { super.onCreate(); mPowerManager = (PowerManager) getSystemService(Context.POWER_SERVICE); mWakeLock = mPowerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.ON_AFTER_RELEASE, TAG); } @Override public void onStart(Intent intent, int startId) { super.onStart(intent, startId); mWakeLock.acquire(); } // No release

  • multiple regionDidChangeAnimated calls - what gives?

    - by mvexel
    I have a MKMapView inside a UITableView as a custom cell (don't ask ;) - don't know if it matters really), for which I register a regionDidChangeAnimated delegate method. This method gets called three times when the UITableView is loaded - once with the actual region and then two more times with a region that is way off. In the simulator, I consistently get a region with center (+37.43997405, -97.03125000). On the device, it seems to depend on the location reported by the location manager, which initializes the map view. Why am I getting three regionDidChangeAnimated calls? And why are the center coordinates for the last two of them off? This is the code I use to get the center coordinates: - (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated { CLLocation *l = [[CLLocation alloc] initWithLatitude:self.mapView.centerCoordinate.latitude longitude:self.mapView.centerCoordinate.longitude]; (....)

  • the correct actionscript to find if object already exists

    - by touB
    I have a Rect object that I'd like to create and set its properties only once. After that, I want to just modify its properties since it already exists. This is my general idea if(theRect == undefined){ Alert.show("creating"); var theRect:Rect = new Rect(); //then set properties addElement(theRect); //then add it using addElement because addChild() does not work } else { Alert.show("updating"); //no need to create it since it's already been created //just access and change the properties } I tried several ways and combinations for the if conditional check: if(theRect == undefined){ if(theRect == null){ declaring and not declaring `var theRect:Rect;` before the if check declaring and instantiating to null before the if check `var theRect:Rect = null;` but can't get the desired effect. Everytime this code block runs, and depending on which version I've used, it either gives me a "can't access null object" error or the if statement always evaluates to true and creates a new Rect object and I get the "creating" Alert. What's the right way of creating that Rect but only if doesn't exist?

  • GWT - Retrieve size of a widget that is not displayed

    - by Garagos
    I need to set the size of an absolutePanel regarding to its child size, but the getOffset* methods return 0 because (i think) the child as not been displayed yet. A Quick example: AbsolutePanel aPanel = new AbsolutePanel(); HTML text = new HTML(/*variable lenght text*/); int xPosition = 20; // actually variable aPanel.add(text, xPosition, 0); aPanel.setSize(xPosition + text .getOffsetWidth() + "px", "50px"); // 20px 50px I could also solve my problem by using the AbsolutePanel size to set the child position and size: AbsolutePanel aPanel = new AbsolutePanel(); aPanel.setSize("100%", "50px"); HTML text = new HTML(/*variable lenght text*/); int xPosition = aPanel.getOffsetWidth() / 3; // Once again, getOffsetWidth() returns 0; aPanel.add(text, xPosition, 0); In both case, i have to find a way to either: retrieve the size of a widget that has not been displayed be notified when a widget is displayed

  • Change master table PK and update related table FK (changing PK from Autoincrement to UUID on Mysql)

    - by eleonzx
    I have two related tables: Groups and Clients. Clients belongs to Groups so I have a foreign key "group_id" that references the group a client belongs to. I'm changing the Group id from an autoincrement to a UUID. So what I need is to generate a UUID for each Group and update the Clients table at once to reflect the changes and keep the records related. Is there a way to do this with multiple-table update on MySQL? Adding tables definitions for clarification. CREATE TABLE `groups` ( `id` char(36) NOT NULL, `name` varchar(255) DEFAULT NULL, `created` datetime DEFAULT NULL, `modified` datetime DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8$$ CREATE TABLE `clients` ( `id` char(36) NOT NULL, `name` varchar(255) NOT NULL, `group_id` char(36) DEFAULT NULL, `active` tinyint(1) DEFAULT '1' PRIMARY KEY (`id`), KEY `fkgp` (`group_id`), CONSTRAINT `fkgp` FOREIGN KEY (`group_id`) REFERENCES `groups` (`id`) ON DELETE NO ACTION ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8$$

  • What would be the best approach for this?

    - by chobo
    I have a site which has an area that requires authentication. Right now I use the roles attribute on all the controllers in that area, and I run a query to retrieve that users ID, and all their settings. It seems like a code or design smell to me that I am retrieving the userid and settings each time a controller in that area loads up? I'm not sure if I should be using sessions, or if ASP.Net MVC 2.0 provides some unique way to handle this. Another concern is security. Overall, I don't really know which way to turn. Design wise I would like the userId and settings retrieved only once when the user logs into the area. Right now I grab the userId each time a controller loads up, and then if required, I query the database for their settings each time as well.
