  • get the response of a jquery ajax call as an input parameter of another function:

    - by Nauman Bashir
    Hello, Is it possible to make a jquery ajax call, and get the response as an input parameter of another function: here is an example, i have the following function call at a location: updateTips(validationTextObject,objUsers.fetchAvailable()); the objUsers.fetchAvailable() function makes a ajax call to the server. The callback function on successful call would be something like this. It is being used to process the result BHUsers.prototype.recvAvailable= function(response){ // some kind of processing over here return (response["status"] == "OK")? "Available" : "Not Available"; } I want that fuction to return the processed result which can be used as a parameter to the function updateTips The primary goal of this is to be able to do all of this for multiple scenarios, rather than writing multiple functions for the same call. Also i want the calling and the response processing functions to just do what they are doing. I dont want to add html objects into it. Any Clues?

  • Eclipse + Git: Can't add files to my repository

    - by Stegeman
    I use Eclipse (Helios) with PDT and egit. I have a project without versioning, so I created a git repository for it by doing: Team -> Share Project When I try to add the files of my project to the repository: Team -> Add I get an exception: Failed to add resource to index Failed to add resource to index Exception caught during execution of add command When I add the files manually on the command line, everything is working fine. Any ideas?

  • iphone - testing if an object exists

    - by Mike
    I have several apps in my app that can become nil at some point and I have methods that in theory are used to put these objects to nil. But, if I try to put to nil an object that does not exist, the app will crash. for example... [object1 release]; object1 = nil; //... and after that [object removeFromSuperview]; // this will crash Then I thought, why not testing to see if the object exists before removing... if (object1 != nil) [object removeFromSuperview]; // this will crash too, because object1 cannot be tested for nil because it does not exist How can I check if the object exists before testing if it is nil? something as if (object exists( { if(object != nil)) [object removeFromSuperview) } is this possible?

  • csutom converter in XStream

    - by Raja Chandra Rangineni
    Hi All, I am using XStream to serialize my Objects to XML format. The formatted xml that I get is as below: node1, node2, node 3 are attributes of pojo,DetailDollars 100 25 10 I have requirement where in I have to calucluate a percentage, for example 100/ 25 and add the new node to the existing ones. So, the final output should be : 100 25 10 4 I wrote a custom converter and registered to my xstream object. public void marshal(..){ writer.startNode("node4"); writer.setValue(getNode1()/ getnode2() ); writer.endNode(); } But, the xml stream I get has only the new node: 4 I am not sure which xstream api would get me the desired format. could you please help me with this . Thanks, Raja chandra Rangineni.

  • Android app (with felix) crashes with LinearAlloc exceeded capacity

    - by user1106000
    I am running apache felix and an osgi app on android (3.2). This works pretty well so far, but I have rather large chunks of data to load into the application (osgi bundles). The problem with that is that when I load the biggest chunk of data I get LinearAlloc exceeded capacity The error seems to come from LinearAlloc.c \#define DEFAULT_MAX_LENGTH (4*1024*1024) if (nextOffset > pHdr->mapLength) { /* * We don't have to abort here. We could fall back on the system * malloc(), and have our "free" call figure out what to do. Only * works if the users of these functions actually free everything * they allocate. */ LOGE("LinearAlloc exceeded capacity, last=%d\n", (int) size); dvmAbort(); } afaik in 3.2/4.x it is even 8*1024*1024, but I still hit that limit. I'm looking to get better insight on what causes this problem and how I might possibly be able to fix it. Any help would be appreciated.

  • playing only part of a sound using FMOD

    - by carneades
    I'm trying to play only part of a sound using FMOD, say frames 50000-100000 of a 200000 frame file. I have found a couple of ways to seek forward (i.e. to start playback at frame 50000) but I have not found a way to make sure the sound stops playing at 100000. Is there any way FMOD can natively do this without having to add lbsndfile or the like into the picture? I should also mention that I am using the streaming option. I have to assume that these sounds are arbitrarily large and cannot be comfortably/quickly loaded into memory.

  • HttpModule Init method is called several times - why?

    - by MartinF
    I was creating a http module and while debugging I noticed something which at first (at least) seemed like weird behaviour. When i set a breakpoint in the init method of the httpmodule i can see that the http module init method is being called several times even though i have only started up the website for debugging and made one single request (sometimes it is hit only 1 time, other times as many as 10 times). I know that I should expect several instances of the HttpApplication to be running and for each the http modules will be created, but when i request a single page it should be handled by a single http application object and therefore only fire the events associated once, but still it fires the events several times for each request which makes no sense - other than it must have been added several times within that httpApplication - which means it is the same httpmodule init method which is being called every time and not a new http application being created each time it hits my break point (see my code example at the bottom etc.). What could be going wrong here ? is it because i am debugging and set a breakpoint in the http module? It have noticed that it seems that if i startup the website for debugging and quickly step over the breakpoint in the httpmodule it will only hit the init method once and the same goes for the eventhandler. If I instead let it hang at the breakpoint for a few seconds the init method is being called several times (seems like it depends on how long time i wait before stepping over the breakpoint). Maybe this could be some build in feature to make sure that the httpmodule is initialised and the http application can serve requests , but it also seems like something that could have catastrophic consequences. This could seem logical, as it might be trying to finish the request and since i have set the break point it thinks something have gone wrong and try to call the init method again ? soo it can handle the request ? But is this what is happening and is everything fine (i am just guessing), or is it a real problem ? What i am specially concerned about is that if something makes it hang on the "production/live" server for a few seconds a lot of event handlers are added through the init and therefore each request to the page suddenly fires the eventhandler several times. This behaviour could quickly bring any site down. I have looked at the "original" .net code used for the httpmodules for formsauthentication and the rolemanagermodule etc but my code isnt any different that those modules uses. My code looks like this. public void Init(HttpApplication app) { if (CommunityAuthenticationIntegration.IsEnabled) { FormsAuthenticationModule formsAuthModule = (FormsAuthenticationModule) app.Modules["FormsAuthentication"]; formsAuthModule.Authenticate += new FormsAuthenticationEventHandler(this.OnAuthenticate); } } here is an example how it is done in the RoleManagerModule from the .NET framework public void Init(HttpApplication app) { if (Roles.Enabled) { app.PostAuthenticateRequest += new EventHandler(this.OnEnter); app.EndRequest += new EventHandler(this.OnLeave); } } Do anyone know what is going on? (i just hope someone out there can tell me why this is happening and assure me that everything is perfectly fine) :) UPDATE: I have tried to narrow down the problem and so far i have found that the Init method being called is always on a new object of my http module (contary to what i thought before). I seems that for the first request (when starting up the site) all of the HttpApplication objects being created and its modules are all trying to serve the first request and therefore all hit the eventhandler that is being added. I cant really figure out why this is happening. If i request another page all the HttpApplication's created (and their moduless) will again try to serve the request causing it to hit the eventhandler multiple times. But it also seems that if i then jump back to the first page (or another one) only one HttpApplication will start to take care of the request and everything is as expected - as long as i dont let it hang at a break point. If i let it hang at a breakpoint it begins to create new HttpApplication's objects and starts adding HttpApplications (more than 1) to serve/handle the request (which is already in process of being served by the HttpApplication which is currently stopped at the breakpoint). I guess or hope that it might be some intelligent "behind the scenes" way of helping to distribute and handle load and / or errors. But I have no clue. I hope some out there can assure me that it is perfectly fine and how it is supposed to be?

  • Best practices for Subversion and Visual Studio projects

    - by Alex Marshall
    I've recently started working on various C# projects in Visual Studio as part of a plan for a large scale system that will be used to replace our current system that's built from a cobbling-together of various programs and scripts written in C and Perl. The projects I'm now working on have reached critical mass for being committed to subversion. I was wondering what should and should not be committed to the repository for Visual Studio projects. I know that it's going to generate various files that are just build-artifacts and don't really need to be committed, and I was wondering if anybody had any advice for properly using SVN with Visual Studio. At the moment, I'm using an SVN 1.6 server with Visual Studio 2010 beta. Any advice, opinions are welcome.

  • iPhone app memory leak

    - by Marian Busoi
    Any idea why this code gives me a memory leak? As you can see, I'm running out of ideas as to what I can do to stop it. (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; NSArray *allSketches = [project.sketches allObjects]; NSMutableArray *temp = [[NSMutableArray alloc] initWithArray:allSketches]; if(sketchesArray != nil) [sketchesArray release]; [self setSketchesArray:temp]; [allSketches release]; allSketches = nil; [temp release]; temp = nil; } I also release sketchesArray inside viewDidDissapear. I'm not using viewDidLoad and dealloc to init/release these objects as what I am doing requires me to use viewWillAppear and viewDidDissapear. Thanks

  • Best way to produce automated exports in tab-delimited form from Teradata?

    - by Cade Roux
    I would like to be able to produce a file by running a command or batch which basically exports a table or view (SELECT * FROM tbl), in text form (default conversions to text for dates, numbers, etc are fine), tab-delimited, with NULLs being converted to empty field (i.e. a NULL colum would have no space between tab characters, with appropriate line termination (CRLF or Windows), preferably also with column headings. This is the same export I can get in SQL Assistant 12.0, but choosing the export option, using tab delimiter, setting my NULL value to '' and including column headings. I have been unable to find the right combination of options - the closest I have gotten is by building a single column with CAST and '09'XC, but the rows still have a leading 2-byte length indicator in most settings I have tried. I would prefer not to have to build large strings for the various different tables.

  • Using Propel ORM in my own custom classes

    - by Stick it to THE MAN
    I am refactoring a few classes I wrote a while ago, into my Symfony project (v1.3.2 with Propel ORM). The classes originally used direct connections to the database, I want to refactor those classes (stored in $(SF_LIB_DIR)) so that I can call propel and also use the ORM objects. To clarify, So for example, I want to be able to use code like this in my custom classes: try { $con = Propel::getConnection(); $c = new Criteria(); $foo = new PropelORMFooObject(); $foobar = PropelORMFooBarObjectPeer::fetch($c); //set fields etc $foo->setFooBar($foobar); // now save using obtained connection .. $foo->save($con) }catch(SomeException $e) { //deal with it } I assume that I will need to add some require_once() statements to my custom libraries, but it is not clear which files to include. Does anyone know how to do this?

  • Best practices for organizing .NET P/Invoke code to Win32 APIs

    - by Paul Sasik
    I am refactoring a large and complicated code base in .NET that makes heavy use of P/Invoke to Win32 APIs. The structure of the project is not the greatest and I am finding DllImport statements all over the place, very often duplicated for the same function, and also declared in a variety of ways: The import directives and methods are sometimes declared as public, sometimes private, sometimes as static and sometimes as instance methods. My worry is that refactoring may have unintended consequences but this might be unavoidable. Are there documented best practices I can follow that can help me out? My instict is to organize a static/shared Win32 P/Invoke API class that lists all of these methods and associated constants in one file... (The code base is made up of over 20 projects with a lot of windows message passing and cross-thread calls. It's also a VB.NET project upgraded from VB6 if that makes a difference.)

  • Jquery: Preload an image on request with a callback function?

    - by tarnfeld
    Hey, I'm helping out a friend with a website he's developing and we are having trouble with preloading images on request. Basically, when the user clicks on a thumbnail of the product a <div> slides down that includes a scrolling carrousel of large images. In total there are about 20MB of images that could be loaded in (if you did them all) so preloading them on the page load would not be an option. Is there a way that we could call a javascript function that begins to preload about 4 images and then when it's done it has a callback function? Thanks! P.S. We are using jQuery on the page...

  • How to manipulate and print a chart in MS Excel from AppleScript?

    - by Stu Thompson
    With an existing chart in a MS Excel for Mac 2008, in AppleScript, I am trying to do two things: Rotate a 3D chart 1° Save the chart as a image (png) From what I've found on the Intertubes, it seems possible. But AppleScript's awkward verbosity and the lack of non-trivial MS Excel AppleScript examples on the web are too much for me to overcome. Just for the saving part, this is what I have so far: tell application "Microsoft Excel" activate object worksheet "iozone-16" set cht to chart object 1 of active sheet tell cht #save as chart object [picture type enumeration] [file name Unicode text] #Argh!!! end tell end tell The 'rotate 1°' task seems to involve "internal objects", but that is as far as I've gotten.

  • ByteBuffer recycling class

    - by Chris Dennett
    Hi everyone, I'm wonder how I'd code up a ByteBuffer recycling class that can get me a ByteBuffer which is at least as big as the specified length, and which can lock up ByteBuffer objects in use to prevent their use while they are being used by my code. This would prevent re-construction of DirectByteBuffers and such over and over, instead using existing ones. Is there an existing Java library which can do this very effectively? I know Javolution can work with object recycling, but does that extend to the ByteBuffer class in this context with the requirements set out? Cheers, Chris

  • How to investigate if opencl is possible for an algorithm

    - by Marnix
    I have a heavy-duty algorithm in C# that takes two large Bitmaps of about 10000x5000 and performs photo and ray collision operations on a 3D model to map photos on the 3D model. I would like to know if it is possible to convert such an algorithm to OpenCL to optimize parallel operations during the algorithm. But before asking you to go into the details of the algorithm, I would like to know how I can investigate if my algorithm is convertible to OpenCL. I am not experienced in OpenCL and I would like to know if it is worth it to get into it and learn how it works. Are there things I have to look for that will definitely not work on the graphics card? (for-loops, recursion) Update: My algorithm goes something like: foreach photo split the photo in 64x64 blocks foreach block cast a ray from the camera to the 3D model foreach triangle in 3D model perform raycheck

  • Java: where should I put anonymous listener logic code?

    - by tulskiy
    Hi, we had a debate at work about what is the best practice for using listeners in java: whether listener logic should stay in the anonymous class, or it should be in a separate method, for example: button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { // code here } }); or button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { buttonPressed(); } }); private void buttonPressed() { // code here } which is the recommended way in terms of readability and maintainability? I prefer to keep the code inside the listener and only if gets too large, make it an inner class. Here I assume that the code is not duplicated anywhere else. Thank you.

  • How do I shrink my SQL Server Database?

    - by Rory Becker
    I have a Database nearly 1.9Gb Database in size MSDE2000 does not allow DBs that exceed 2.0Gb I need to shrink this DB (and many like it at various client locations) I have found and deleted many 100's of 1000's of records which are considered unneeded. these records account for a large percentage of some of the main (largest) tables in the Database. Therefore it's reasonable to assume much space should now be retrievable. So now I need to shrink the DB to account for the missing records I execute "DBCC ShrinkDatabase('MyDB')"......No effect. I have tried the various shrink facilities provided in MSSMS.... Still no effect. I have backed up the database and restored it... Still no effect. Still 1.9Gb Why? Whatever procedure I eventually find needs to be replayable on a client machine with access to nothing other than OSql or similar.

  • Debugging Objective C JNI code

    - by thatidiotguy
    Here is the situation: I have a client's java project open in eclipse. It uses a JNI library created by an Xcode Objective C project. Is there any good way for me to debug the C code from eclipse when I execute the Java code? Obviously eclipse's default debugger cannot step into the jni library file and we lose the thread (thread meaning investigative thread here, not programming thread). Any advice or input is appreciated as the code base is large enough that following the client's code will be radically faster than other options. Thanks. EDIT: It should be noted that the reason that the jni library is written in Objective-C is because it is integrating with Mac OSX. It is using the Cocoa framework to integrate with the Apple speech api.

  • Default Object being modified because of LINQ Query

    - by msarchet
    I'm doing the following code to filter a list of objects before it gets sent off to be printed. Dim printList As New List(Of dispillPatient) For Each pat As dispillPatient In patList If (From meds In pat.Medication Select meds Where meds.Print = True).Count > 0 Then Dim patAdd As New dispillPatient patAdd = pat patAdd.Medication = DirectCast((From meds In pat.Medication Select meds Where meds.Print = True).ToList, List(Of dispillMedication)) printList.Add(patAdd) End If Next What is happening is patList, which is my initial list, for every dispillPatient inside of it, that specific patients Medication object (which is another list), is being shorten to the list that is returned to the patAdd object. I think this has something to do with both the way that .NET makes the copy of my pat object when I do patAdd = pat and the LINQ query that I'm using. Has anyone had a similar issue before and\or what can I do to keep my initial list from getting truncated. Thanks

  • Seam/JSF/Facelets Compiler or Validator (equivalent of JspC for JSP)

    - by Drew
    Is there such a thing as JspC in the Seam/JSF/Facelets world? I used the Tomcat's JspC to validate a JSP/Struts application to validate if there are typos in the JSPs or some JSP was calling a Java function that didn't exist, etc. etc. From time to time I come across bugs in my current project (Seam/Facelets/RichFaces) where it's caused by a typo in action/value binding. And I think bugs like these can be caught using a program. Just wondering if someone has already written one. Basically a tool that can validate if the method/value binding are correct. I know this would be specially hard in Seam since names are Context sensitive and the tool should somehow figure out what the context is. But I think it should be easier to just check if the names are valid and the Objects bound to those names have the methods and/or properties being referred to in the JSF page. Thanks
