• Develop iPhone application remotely?

  - by ANE

  4 java developers are new to iPod Touch/iPhone app development. They have an idea for an app. They have never used Xcode or Macs before. Instead of spending money for a new iMac or Mac Mini for each of them, my boss would like to sell them a $999 Apple server, hosted at a facility connected a single T1 line, and have all 4 people work remotely in Xcode. Is this feasible? Is anyone doing anything like this? Specifically, is 1 T1 enough for realistic remote app development? Would they have to work in black & white via Logmein or Gotomeeting to get decent speed? Can four people work remotely together on an Xcode project at the same time? Do they absolutely need their own Macs to connect their iPod Touches or iPhones physically to, or can they connect to their existing PCs with iTunes and install their in-development apps that way?

• Using PHP's $_COOKIE to create cookie.txt for cURL

  - by boogie

  Hi, I'm running Drupal and Mediawiki on my server under the same domain. They are connected to each other with extensions/modules. Meaning if I log in to Mediawiki, it automatically logs into Drupal also. Mediawiki has some extensions that filter the information shown on the page. What I want to do is to show that filtered information from Mediawiki on my Drupal page. I'm trying to fetch the data with PHP cURL, but I'm not able to force it to use the login information. How can I convert PHP's $_COOKIE into cURL cookie.txt format? I suppose after that I'm able to fetch the data from Mediawiki with the right permissions. This is what print_r($_COOKIE) outputs: [wiki_session] = gg05lhd6pcfs5g6iokhoo0gue7 [wikiUserName] = WikiSysop [wikiLoggedOut] = 20100510110913 [wikiUserID] = 1 [wikiToken] = 52cdb19a7b4a43e5a2f86939e4f54941 Thanks for any help!

• Intercommunication between Java Chat Servers

  - by Pravingate

  I have a application in which I am using socket programming , having this(image) scenario. Where number of clients will try to connect Broadcast server. Now here I am managing load through LVS(Load balancer). so as a example shown in image, suppose 200 clients will wish to login for broadcast they will be distributed as 100 users on server 1 and another 100 users on server 2.clients will get connected to servers using TCP connection. Now I am maintaining user information on server side in arraylist which will be stored in heap memory,Now the problem is if client wish to broadcast to all logged in users, but that particular client is logged in server 1. and so client will not be able to broadcast another 100 users from server 2. Because both ther servers are unaware about each others state. please suggest to solve this scenario by whatever means you want.

• AJAX Autocomplete appears at a random vertical position, not touching the textbox

  - by Tim

  Hi, I am using the AJAX Autocomplete extender for ASP.NET 2. Everything works fine...I am calling a webservice which gets me the values to fill the drop down with after 3 letters are typed into certain es. I have set the maxheight attribute and am using a scrollbar in case there are more entries than would fit that height. However, I notice that in some cases, the drop down appears at a random position on the screen, i.e. rather than connected to the relevant textbox, sometimes it appears with its entries above the textbox, not touching it at all. Sometimes it would have just one entry and it would appear in the middle of the screen vertically above the textbox it is associated to. Is there a reason why this is happening?

• samsung galaxy tab 4 not recognized by eclipse

  - by michael

  the just released samsung galaxy tab 4 tablet does bring up the 'autoplay' box with device options when connected, but is not being recognized by eclipse, nothing shows in the device window. I have enabled debugging on the galaxy tab, including tapping the 'about' box 7 times to make the developer options magically appear. it runs kitkat and the Samsung site has a 'no data available' under the driver tab for this device. since it just came out at target last week it's unlikely there would be a new driver anyway, which has been the usual suggestion for this question on older models.

• embedded dev. question - how to break free from a faulty serial port opening?

  - by user347266

  Under WindowsCE, C++ project, I'm trying to work with devices connected via both "real" serial ports and/or serial-to-usb wrappers ("virtual" serial ports); my problem is - when I try to open the port, if something goes wrong, the function never returns and the system goes into some non-responsive state and has to be eventually rebooted. I need to open the ports from the main thread. The question is - how can I make it happen in a controlled way?? this is the opening code snippet: std::ostringstream device_name; device_name << "\\.\COM" << port; m_port = ::CreateFile(device_name.str().c_str(), GENERIC_READ | GENERIC_WRITE, 0, // exclusive access NULL, // no security OPEN_EXISTING, FILE_FLAG_OVERLAPPED, // overlapped I/O NULL); // null template any suggestions would be greatly appreciated thanks!

• The best practice to setup hierarchy data

  - by eski

  I'm trying to figure out the best practice to setup hierarchy data that i take from a database into some contoller that would show the hierachy. Basicly this would look like a normal tree but when you press the items that are under "chapters" you get a link to another page. I have these tables and this is the way they are connected Period Courses Subjects Chapters I select Period from a DropDownBox and then i want all the courses in that period to line up. Under each course would be the subject and under them are the chapers, typical hierarchy. The tables are linked together with refrences to each other in linear way. I have tried to use treeview to show this, but dont understand how to do it. I though i could use <ul><il> tags and do it at runtime. Reapeter or datalist, possible ? Is it better to do this with databinding in XAML or in code ?

• Possible to not use ID field but another column name? in Lift

  - by bstevens90

  I am connected to a oracle database from a scala/lift webapp. I have been able to successfully pull information from the database as I wished but am having one issue. For each table I want to access I am required to add an ID field so that the app will work with the trait IdPK. What mapper class or trait can I use to override this? I have been trying to find one but been unable to locate it. Figured people have not always had an ID field on every table they make that is just called ID... class DN_REC extends LongKeyedMapper[DN_REC] with IdPK { def getSingleton = DN_REC object dn_rec_id extends MappedInt(this){ } This is what I am talking about. I would like to use the dn_rec_id as my primary key as it is on the table. Thanks

• Multiple svn projects into one git repository?

  - by trondgzi

  Hi, I have started to use git-svn for some of my work to be able to do local commits. This works great for projects that use standard svn layout. Recently I started working on a Java project that is split into multiple connected modules (20-25), and each module have its own root folder in the same svn repo with its own trunk/branches/tags. svnrepo/ module-1 trunk branches tags module-N trunk branches tags I have cloned each and every module with git svn clone -s /path/to/svnrepo/module[1-N]. The "problem" is that when I want to do git svn rebase on all modules i have to do it N times. I have tried to do git svn clone /path/to/svnrepo/ do avoid doing the rebase operation N times, but that leaves me with a directory layout that is the same as in the svn repo. Is there a way that I can track all the trunks of all modules in one git repo? So that I get a directory layout like this within my git repository: module-1 module-2 module-N

• Making a many-to-many relationship using DataRelations object

  - by dotnetdev

  Hi, I have about 200 tables which need to relate to another table in a many-to-many fashion. I have the tables (including the intersection table) ready IN SQL Server. How can I write code using the data relation object to make the relationship? The tables are: PartStatPartName PartsMaterialsIntersection << Materials The materials table needs to have a foreign key from the PartStatPartName table. I tried various approaches using the DataRelation class but the change did not sync to SQL Server, despite being connected and adding the relation, and then calling AcceptChanges() on the dataset. Any guidance much appreciated. I have seen some threads covering the same problem but need an example in code so I can follow the right method. Thanks

• Getting local My Documents folder path

  - by smsrecv

  In my C++/WinAPI application I get the My Documents folder path using this code: wchar_t path[MAX_PATH]; SHGetFolderPathW(NULL,CSIDL_PERSONAL,NULL,SHGFP_TYPE_CURRENT,path); One of the users runs my program on a pc connected to his corporate network. He has the My Documents folder on a network. So my code returns something like \paq\user.name$\My Documents Though he says he has a local copy of My Documents. The problem is that when he 'swaps VPN', the online My Documents becomes unavailable and my program crashes with the system error code 64 "The specified network name is no longer available" ( it tries to write to the file opened in the online my docs folder). How can I always get the local My Documents folder path using C++/WinAPI?

• Sync framework 2.0 smart device to server

  - by Oll

  We have a requirement very similar to that shown in the Occasionally Connected Application (OCA) diagram on the Introduction to Sync Framework Database Synchronization article. We can't however find any examples on how the clients at the bottom are syncing between each other. Particularly, how a smart device syncs with another client each having a local .sdf database. There are lots of examples of a smart device to a server over wcf where the server is running full sql but not smart device to server with local cache. Does anyone have any ideas or examples. Thanks

• Is there a jquery clone of ext.js' toolbar?

  - by fbuchinger

  I'm looking for a jquery equivalent of ext.js' toolbar (http://dev.sencha.com/deploy/dev/examples/menu/menus.html). To be more precisely, my requirements are the following: the toolbar should consist of iconic and textual buttons and dropdown widgets buttons should either trigger actions directly or open submenus buttons and submenus should have the ability to remember the last selected state buttonsets should group multiple buttons and only allow one of them to be active In short words, I'm looking for a real toolbar in jquery and not for some modified site menu. I experimented with the button/buttonset/menu widget in jquery ui 1.9m2, but found its IE performance rather poor. It also felt awkward to combine these isolated widgets into a logically connected toolbar. Does anyone know of a better jquery toolbar plugin?

• Get a return value from a screen'd command

  - by AndyMac

  I'm running a process in a screen (on Ubuntu 13.10, if it matters). I can execute a command within that screen with: screen -p 0 -X eval 'stuff \"$command\"\015' I'm not 100% sure what this command is doing to begin with, though it's functioning correctly. The reason behind it is I'm running a Minecraft server (still) and this screens in to the correct screen, and throws the command on the running command line. So that's good, so far. But what I'd like is to be able to run this command with a return value. So for example, if I were to run a "list" command, it'd tell me how many people and who is online, but I need to capture that output and put it somewhere. Anyone know of a way to accomplish this? I can't tell the minecraft server command line to redirect the output somewhere else since it doesn't have direct command line access, so the only way I could do this would be to grab all output of the screen while I'm connected ... but I'm not sure if that's possible.

• UIImage for UIImageView is nil

  - by yeesterbunny

  I'm having problem displaying UIImage in UIImageView. I looked all over stackoverflow for similar questions, but none of the fixes helped me. The image is indeed in my bundle File Inspector - Target Membership is checked for the image IBOutlet is connected (I have tried both using IBOutlet and doing it programmatically) Both png nor jpg works Here's the code for using Interface Builder - //@property and @synthesize set for IBOutlet UIImageView *imageView - (void)viewDidLoad { [super viewDidLoad]; NSAssert(self.imageView, @"self.imageView is nil. Check your IBOutlet connection"); UIImage *image = [UIImage imageNamed:@"banner.jpg"]; NSAssert(image, @"image is nil"); self.imageView.image = image; } This code will terminate with NSAssert, printing in the console that 'image is nil'. I also tried selecting the Image directly from the attributes inspector: However it still doesn't show the image (still terminates with NSAssert - 'image is nil'). Any help or suggestions will be greatly appreciated. Thanks

• What does that mean? "mi_cmd_stack_list_frames: Not enough frames in stack."

  - by HelloMoon

  Debugger is telling me this, when I run my app on device: Program received signal: “EXC_BAD_ACCESS”. mi_cmd_stack_list_frames: Not enough frames in stack. mi_cmd_stack_list_frames: Not enough frames in stack. I don't get information about where in code that happens. That's all I get. Any idea what that could mean? The app crashes after that. When the device is not connected to the mac, it still crashes, so not a debugger problem.

• Where is the best place to start learning Java Socket Programming?

  - by MarcoBoomTing

  I wish to create a Java Socket server which can be connected to using Javascript and/or Flash. I have experience in Connecting to sockets in flash, and using a comet like system in Ajax. I wish to make a live communication system, which will intale multiple connections to the server from various clients, needing almost instant communication between peers. I coded a system like this in PHP but I want to convert it to Java, simply because I don't want the PHP engine to be tied up on this Sever, as it serves all the web stuff normally on the site, and i've heard is more powerful for this sort of thing. Just looking for advice on where I can start learning how to write this sort of system using Java? I have previous coding experience in PHP, Javascript, Adobe Air and AS3 if That helps?

• Confused as to why my PHP include isn't working

  - by Sam

  I had a prototype of my website working correctly, meaning it connected to the database correctly. This was done with just one file called "connect.php" which had mysql_connect() and such inside it. I then separated the connect information into to separate files, one containing the account information (account.php) and one containing the connect function (connect.php), with correct information (I triple checked) and it isn't connecting properly. All I can think of is that I'm not including it the right way. This is what I have in a file: <?php include('account.php'); include('connect.php'); include('functions.php'); ..... ?>

• Extracting fixture for one specific object

  - by emostar

  I want to extract the necessary code to recreate a set of Models from my production environment to my testing environment. There is something wrong in the data that causes an Exception, and I need the data in my local environment to do debugging. I looked at django-extensions and the dumpscript command is almost what I want. But I have many other objects connected to this one via foreign keys. Is there an easy way to extract the object by primary key, and all other objects that are related to it?

• Secure Webservice?

  - by cam

  I'm trying to create a secure webservice (that provides simple database data) with PHP that can be connected to through my Silverlight application. I don't know enough about PHP to be able to see another way to do this. The webservice should only be accessible through the client, and only with the proper username/password. The only two ways I can imagine to do this would be by passing the username/password hash via URL, or use a "hidden form" and do it via POST_. I'm just trying to get past this point, I'm the sole developer on this project and I'm just trying to get past this PHP webservice part so I can get back to being an application programmer :) Normally, I would learn PHP, but I'm on the clock, so I'm just looking for a point in the right direction on how to achieve this!

• Advice regarding Java frameworks [closed]

  - by Mixiul

  I am in the process of creating a website/phone application using JQuery Mobile and PhoneGap. I am hoping to add openID support so users can login in with pre-existing accounts. It will be necessary for me to have a database with a few tables to enable me to implement all the core functionality I desire. I haven't really had much experience with frameworks before, the closest thing I have done to this is create a basic website using php that connected to a MySql database stored on the machine that hosted the apache webserver. The interaction with the database won't be complex. I am required to use a java framework for the backend of my application. My question is which java framework is most suitable (flexible and straight forward to learn)? Any advice you guys can provide is greatly appreciated. Thanks

I want to implement this in a software tool to. There seems to be no file locked. Perhaps it is done via ebookUsb.dll. Does anybody know how this is done from any programming language? I like to see an example.

• How do I make a TCP connection between 2 servers if both can start the connection ?

  - by DeeD

  I have a defined number of servers that can locally process data in their own way. But after some time I want to synchronize some states that are common on each server. My idea was that establish a TCP connection from each server to the other servers like a mesh network. My problem is that in what order do I make the connections since there is no "master" server here, so that each server is responsible for creating there own connections to each server. My idea was that make each server connect and if the server that is getting connected already has a connection to the connecting server, then just drop the connection. But how do I handle the fact that 2 servers is trying to connect at the same time? Because then I get 2 TCP connections instead of 1. Any ideas?
