  • How to set variable before callback is called?

    - by user1995327
    I'm trying to design a webpage... I have a function that I call get all info needed for an idividuals home page. A snippet of the codes is: exports.getHomePageData = function(userId, cb) { var pageData = {}; pageData.userFullName = dbUtil.findNameByUserId(userId, function(err){ if (err) cb(err); }); pageData.classes = dbUtil.findUserClassesByUserId(userId, function(err){ if (err) cb(err); }); cb(pageData); } The problem I'm having is the cb(pageData) is being called before I even finish setting the elements. I've seen that people use the async library to solve this but I was wondering if there was any other way for me to do it without needing more modules... Thanks!

  • Same-directory includes failing on a Fedora server with PHP.

    - by JimmySawczuk
    I have a couple files that look like this: index.php: <?php include('includes/header.php'); ... includes/header.php: <?php include('config.php'); ... The error I get is Warning: require(config.php) [function.require]: failed to open stream: No such file or directory in [dir]/includes/header.php on line 2 Fatal error: require() [function.require]: Failed opening required 'config.php' (include_path='.:/usr/share/pear:/usr/share/php') in [dir]/includes/header.php on line 2 I did some further debugging: when I add the call system('pwd'); to includes/header.php, it shows [dir], where it should say [dir]/includes. Adding the 'includes/' to the include path works, but isn't desirable because that would fail on the production server. The above code works on a production server, and worked fine on my development Fedora server, until I tried to change my development environment so that the Fedora server's document root is a mounted CIFS share. Any ideas? Thanks.

  • How to get the stream of a public Facebook fanpage in php?

    - by Bundy
    Hi, I want to display my public fanpage feed onto my website via the Facebook API without requiring a login. I'm doing this require_once('../includes/classes/facebook-platform/php/facebook.php'); $fb = new Facebook($api_key, $secret); $fb->api_client->stream_get('',$app_id,'0','0','','','','','')); But I get this error Fatal error: Uncaught exception 'FacebookRestClientException' with message 'user id parameter or session key required' in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php:3065 Stack trace: #0 includes/classes/facebook-platform/php/facebookapi_php5_restlib.php(1915): FacebookRestClient->call_method('facebook.stream...', Array) #1 facebook/api.php(12): FacebookRestClient->stream_get('', 13156929019, '0', '0', 30, '', '', '', '') #2 {main} thrown in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php on line 3065 Then I figured, because of 'user id parameter or session key required', to add my user id to the call require_once('../includes/classes/facebook-platform/php/facebook.php'); $fb = new Facebook($api_key, $secret); $fb->api_client->stream_get(502945616,13156929019,$app_id,'0','0','','','','','')); But then I got this error Fatal error: Uncaught exception 'FacebookRestClientException' with message 'Session key invalid or no longer valid' I'm totally clueless :)

  • Combining 2 PHP frameworks that both implement __() internationalization function

    - by mclin
    Never had a question I couldn't google until now, and it may be a doozy: I have a PHP site that combines Wordpress with Kohana - Wordpress for the blog, and Kohana for the custom functionality. This is done using a Wordpress plugin that stitches them together. This works great except they both define a __() internationalization function, with different arguments etc. so once wordpress has overridden kohana's __(), if kohana calls __() it explodes. I'm not that familiar with PHP so this might be naive, but shouldn't this stuff be namespaced? Is there anyway other than changing the source of one or the other framework to allow them to call their own respective __()?

  • Template class implicit copy constructor issues

    - by Nate
    Stepping through my program in gdb, line 108 returns right back to the calling function, and doesn't call the copy constructor in class A, like (I thought) it should: template <class S> class A{ //etc... A( const A & old ){ //do stuff... } //etc... }; template <class T> class B{ //etc... A<T> ReturnsAnA(){ A<T> result; // do some stuff with result return result; //line 108 } //etc... }; Any hints? I've banged my head against the wall about this for 4 hours now, and can't seem to come up with what's happening here.

  • using jquery to load data from mysql database

    - by Ieyasu Sawada
    I'm currently using jquery's ajax feature or whatever they call it. To load data from mysql database. Its working fine, but one of the built in features of this one is to load all the data which is on the database when you press on backspace and there's no character left on the text box. Here's my query: SELECT * FROM prod_table WHERE QTYHAND>0 AND PRODUCT LIKE '$prod%' OR P_DESC LIKE '$desc%' OR CATEGORY LIKE '$cat%' As you can see I only want to load the products which has greater than 0 quantity on hand. I'm using this code to communicate to the php file which has the query on it: $('#inp').keyup(function(){ var inpval=$('#inp').val(); $.ajax({ type: 'POST', data: ({p : inpval}), url: 'querys.php', success: function(data) { $('.result').html(data); } }); }); Is it possible to also filter the data that it outputs so that when I press on backspace and there's no character left. The only products that's going to display are those with greater than 0 quantity?

  • Use LINQ to SQL results inside SQL Server stored procedure

    - by ifwdev
    Note: I'm not trying to call a SQL Server stored proc using a L2SQL datacontext. I use LINQPad for some fairly complex "reporting" that takes L2SQL output saved to an Array and is processed further. For example, it's usually much easier to do multiple levels of grouping with LINQ to Objects instead of trying to optimize a T-SQL query to run in a reasonable amount of time. What would be the easiest way to take the end result of one of these "applications" and use that in a SQL Server 2008 stored proc? The idea is to use the data for a Reporting Services Report, rather than copying and pasting into Excel (manual labor). The reports need to be accessible on the report server (not using the Report Server control in an application). I could output CSV and read that somehow via command line exec, but that seems like a hack. Thanks for your help.

  • Any good way to set the exit status of a Cocoa application?

    - by buglesareking
    I have a Cocoa app which interacts with a server and displays a GUI. If there is a fatal error, I display an alert and exit. I'd like to set the exit status to a non-zero value to reflect that an error occurred, for ease of interaction with some other UNIX based tools. Unfortunately I've been unable to find a good way to do so - NSApplication doesn't seem to have any way to set an exit status. At the moment, I've subclassed NSApplication and added an exitStatus ivar (which I set in my app delegate when necessary), then overridden -terminate: so that it calls exit(exitStatus). This works fine, but it seems a bit grungy to me, not to mention that I may be missing something important that the stadnard `terminate: is doing behind the scenes. I can't call [super terminate:sender] in my subclassed method, because that exit()s without giving me a chance to set the status. Am I missing something obvious?

  • Why does _GET in PHP wrongly decodes slash?

    - by Boaz
    Hi, Today I run into some oddity with PHP, which I fail find a proper explanation for in the documentation. Consider the following code: <?php echo $_GET['t']. PHP_EOL; ?> The code is simple - it takes a single t parameter on the url and outputs it back. So if you call it with test.php?t=%5Ca (%5c is a '\'), I expected to see: \a However, this is what I got: $ curl http://localhost/~boaz/test.php?t=%5Ca \\a Notice the double slash. Can anyone explains what's going on and give recipe for retrieving the strings as it was supplied on the URL? Thanks, Boaz

  • Relvance of 'public' contructor in abstract class.

    - by Amby
    Is there any relevance of a 'public' constructor in an abstract class? I can not think of any possible way to use it, in that case shouldn't it be treated as error by compiler (C#, not sure if other languages allow that). Sample Code: internal abstract class Vehicle { public Vehicle() { } } The C# compiler allows this code to compile, while there is no way i can call this contructor from the outside world. It can be called from derived classes only. So shouldn't it allow 'protected' and 'private' modifiers only. Please comment.

  • Best practice to pass a value from pop up control on iPad.

    - by Tattat
    It is an iPad app based on SDK 3.2. I have a MainUIView, that is subclass from UIView, it have a UIButton and a UILabel. When user press the UIButton, the pop up control will be appeared with a table view. When the user select a cell from the table view, the UILabel changes content base on the user click, and the pop up table view will disappear. The question is, how can I pass the "selected cell" to the UILabel. I am thinking making a "middle man" object. When the user click the UIButton, and the "middle man" will pass to the table. When the cell is selected, the "middle man" will store the idx, and call the UILabel change content from the value of "middle man". But I think it is pretty complex to implement, is there any easier way to implement it? thz u.

  • ASP Classic Named Parameter in Paramaterized Query: Must declare the scalar variable

    - by My Alter Ego
    I'm trying to write a parameterized query in ASP Classic, and it's starting to feel like i'm beating my head against a wall. I'm getting the following error: Must declare the scalar variable "@something".

  • Does the order of case in Switch statement can vary the performance?

    - by Bipul
    Let say I have a switch statement as below Switch(alphabet){ case "f": //do something break; case "c": //do something break; case "a": //do something break; case "e": //do something break; } Now suppose I know that the frequency of having Alphabet e is highest followed by a, c and f respectively. So, I just restructured the case statement order and made them as follows. Switch(alphabet){ case "e": //do something break; case "a": //do something break; case "c": //do something break; case "f": //do something break; } Will the second Switch statement better perform(means faster) than the first switch statement? If yes and if in my program I need to call this switch statement say many times, will that be a substantial improvement? Or if not in any how can I use my frequency knowledge to improve the performance? Thanks

  • Data frame linear fit in R

    - by user1247384
    This is perhaps a simple question, but I am n00b.Say I have a data frame with a bunch of columns. I need to call lm function over the column 1 and 2, 1 and 3, and so on. So basically I need to loop over all columns and store the results of the fit as I build the model. The problem I am running into is that lm(df[1]~df[2], data = df) doesnt work. In this case df is the data frame object and df[1] is the first column. What is a good way to do this in a loop, as in access the columns of df in an iterative fashion. Thanks.

  • Using NSThread to solve waiting for image from URL on the iPhone

    - by james.ingham
    So I have the following code in a method which I want to set a UIImageView image to that of one from an online source: [NSThread detachNewThreadSelector:@selector(loadImage) toTarget:self withObject:nil]; Then in the method called by the thread I have this: - (void) loadImage { NSURL *url = [NSURL URLWithString:logoPath]; // logoPath is an NSString with path details NSData *data = [NSData dataWithContentsOfURL:url]; logoImage.image = [UIImage imageWithData:data]; } This works great however I get many warnings within the Debugger Console along the lines of: 2010-05-10 14:30:14.052 ProjectTitle[2930:633f] * _NSAutoreleaseNoPool(): Object 0x169d30 of class NSHTTPURLResponse autoreleased with no pool in place - just leaking This occurs many times each time I call the new thread and then eventually, under no pattern, after calling a few of these threads I get the classic 'EXC_BAD_ACCESS' run-time error. I understand that this is happening because I'm not retaining the object but how can I solve this with the code in 'loadImage' shown above? Thanks

  • Actionscript 2.0 Functions problem and somewhat "global" variable

    - by Joshua
    I have two problems. The first problem is with the following functions; when I call the function in (enterFrame), it doesn't work: onClipEvent (load) { function failwhale(levelNum) { _root.gotoAndStop("fail"); failFrom = levelNum; } function guardSightCollision(guardName, guardSightName) { if (_root.guardName.guardSightName.hitTest(_x, _y+radius, true)) { failwhale(1); } if (_root.guardName.guardSightName.hitTest(_x, _y-radius, true)) { failwhale(1); } if (_root.guardName.guardSightName.hitTest(_x-radius, _y, true)) { failwhale(1); } if (_root.guardName.guardSightName.hitTest(_x+radius, _y, true)) { failwhale(1); } } } onClipEvent (enterFrame) { guardSightCollision(guard1, guard1Sight); } Why doesn't it work?... The second problem lies in the failFrom variable: function failwhale(levelNum) { _root.gotoAndStop("fail"); failFrom = levelNum; } How do I make failFrom a "global" variable in that it can be accessed anywhere (from actionscript in frames and even movieclips)...Right now, when I try to trace failFrom in a different frame, it is "undefined".

  • Read Text From Windows Form

    - by omghai2u
    I would like, if for no other reason that an academic exercise, to be able to read text written to a form on a Windows Application. The program appears to be written in non-.NET, but in .NET terms, I think you would describe the program as having a Form with a Label and I would like to read the text from that label. I believe I can see that text being written to the screen with the User32!TextOut (and in other areas User32!DrawString) function. However, it would be nice if I didn't have to hook that function to get the information I'm looking for, but instead if I could just read it from the form directly. So, given a handle to a Window, is it possible to read the text that has been written to that window with functions like TextOut and DrawString using some similar API or other clever means? Or am I going about this the wrong way? Should I just hook the function and look for the text in every call and pray? Thanks!

  • Android internet connectivity check problem

    - by Chaoz
    Hello, I'm new to Android development and working on an Android application that requires the phone to be connected to the internet, through either Wifi, EDGE or 3G. This is the code that I'm using: public static boolean isConnected() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); return cm.getActiveNetworkInfo().isConnectedOrConnecting(); } I've also set these permissions in the manifest file: <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> This works fine in the emulator running version 1.5 of Android when 3G is enabled, but it crashes when I disable the 3G connection. My application throws a null pointer exception when I call isConnectedOrConnecting(). Hope that anyone knows the solution to this. Thanks in advance!

  • Messaging strategies to connect different systems

    - by n002213f
    I have a system to handle Applications online and a different system to send SMS/Email notifications to applicants on completion using web services. I can't guarantee the availability of the SMS/Email gateway. Option 1 After an application is complete, place a message on a JMS queue. A Message Driven bean receives the message and make a call for the web service, if it fails leave the message on the queue. I suspect (please correct if incorrect) that if the gate way is offline the continuosly try to send the message which might use up valuable resources. Can the above option be refined are are there any other messaging strategies that can be used?

  • Can getAttribute() method of Tomcat ServletContext implementation be called without synchronization?

    - by oo_olo_oo
    I would like to read some parameters during servlet initializtion (in init() method), and store them among servlet context attributes (using getServletContext().setAttribute()). I would like to read these parameters later - during some request processing (using getServletContext().getAttribute()). So, the multiple threads could do this simultaneously. My question is if such an attempt is safe? Could I be sure that multi threaded calls to the getAttribute() don't mess up any internal state of the servlet context? Please take into account that I'm not going to call the setAttribute() anywhere besides the initialization. So, only calls to the getAttribute() are going to be done from multiple threads. But depending on the internal implementation, this also could be dangerous. So, any information about Tomcat's implementation would be appreciated.

  • Confirm delete of record, from method

    - by Melt
    Hi all, How can I pop up a message box to confirm a delete, from inside a method? Normally i would just use the following line in my button: OnClientClick="return confirm('Are you sure you want to delete this comment?');" However this delete method can also be called by a querystring, so I need the confirm message box functionality in the method, please? // delete comment method private void DeleteComment() { int commentid = Int32.Parse(Request.QueryString["c"]); // call our delete method DB.DeleteComment(commentid); } I can't click the button through code, because it doesn't fire the OnClientClick event btnDelete_Click(null, null); Regards Melt
