• ZipArchive php Class - Does it support all servers?

  - by SoLoGHoST

  Ok, just wondering on the versions of PHP that this class is built into. And if they are built into all platforms (OS's). I'm wanting an approach to search through a zip file and place files using file_put_contents in different filepaths within the webroot. In any case, I'm familiar with how to do this with the ZipArchive class, but I'm wondering if using this class would be a good solution and support MOST, if not ALL servers?? I mean, I'd rather not use a method that requires the Server to have it installed. I'm looking for a solution to this that will support at least MOST servers without having to install the class... Thanks :) Also, I'd like to support opening tar.gz and/or .tgz files if possible, but I don't think the ZipArchive class supports this, but perhaps a different built-in php class does??

• Program received signal from GDB: EXC_BAD_ACCESS

  - by user577185

  Well, I'm starting development on the Mac OS X this code that you'll see is in a book that I bought, really basic like Chapter 3. And I can't run it. PLEASE HELP ME: C301.m : #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { if (argc == 1) { NSLog (@"You need to provide a file name"); return -1; } FILE *wordFile = fopen("tmp/words.txt", "r"); char word[100]; while (fgets(word, 100, wordFile)) { word[strlen(word) - 1] = '\0'; NSLog(@"%s is %d characters long", word, strlen(word)); } fclose(wordFile); return 0; } //main The file is in its place. Thank you so much!

• How to make a server.transfer() with a Response.AddHeader("refresh", "seconds") and not get a 404 er

  - by Unlimited071

  Hi all, so this is the scenario: I have a base class for all login-controlled pages: public class SessionControlledPage : Page { protected virtual void Page_Load(Object sender, EventArgs e) { Response.AddHeader("Refresh", Convert.ToString(Session.Timeout * 60 + 5)); if (Session.IsNewSession) { Response.Redirect("~/login.aspx"); } } } And a regularpage.aspx page that inherints from the base class: public partial class RegularPage : SessionControlledPage { override protected void Page_Load(Object sender, EventArgs e) { base.Page_Load(sender, e); Server.Transfer("~/otherpage.aspx"); } } Now let's say the original URL was http://localhost/regularpage.aspx and that Session.Timeout = 5. The problem appears when the refresh happens after the transfer takes place. I'm getting a 404 Not Found error and the URL changes for http://localhost/305. Notice that 5 * 60 + 5 = 305. Do you know why is this happening? got a solution? PD: I use transfer because I need to access some properties of regularpage.aspx on otherpage.aspx, maybe you could provide another solution for this too.

• Eclipse (Springsource Tool Suite 2.3.1) can't resolve dependencies for classes in the same package

  - by Steve

  This started happening when I upgraded my Springsource Toolsuite from 2.3 to 2.3.1. Essentially whenever I do anything, such as open a file, change a file, etc, I have to do a clean. Everything works fine when I do mvn commands on the command line, which leads me to believe that Eclipse is looking in the wrong place for compiled code or something along those lines, although that is entirely superstitious at this point. Example: I make a change to com.foo.mypackage.MyClass. Suddenly a bunch of tests that excercise MyClass get the red x - for class not found! In src/main/test: com.foo.DbUnitTest com.foo.mypackage.FooTest extends DbUnitTest DbUnitTest gets a class not found. I do a clean, and everything is fine. I touch something, and it breaks again :(. I don't really know where to begin on how to troubleshoot this.

• Where to delete model image?

  - by WesDec

  I have a Model with an image field and I want to be able to change the image using a ModelForm. When changing the image, the old image should be deleted and replaced by the new image. I have tried to do this in the clean method of the ModelForm like this: def clean(self): cleaned_data = super(ModelForm, self).clean() old_profile_image = self.instance.image if old_profile_image: old_profile_image.delete(save=False) return cleaned_data This works fine unless the file indicated by the user is not correct (for example if its not an image), which result in the image being deleted without any new images being saved. I would like to know where is the best place to delete the old image? By this I mean where can I be sure that the new image is correct before deleting the old one?

• Tiny MCE ImageManager Plugin, "cant create instance of plugin"

  - by Lofving

  We just bought MCImageManager and went right on to creating our own plugin. I followed http://wiki.moxiecode.com/index.php/MCI … ing_plugin from start to end but got stuck on the last step. After configuring the build.bat file (that comes along the package) it gives me no errors, i checked all paths and it should work but there just is no plugin.dll file anywhere to be found. (The bat file is also linked to the .net 1.4322, that should be changed by you at tinyMCE in my opinion) To circumvent that problem I started a new project and compiled the plugin.dll through Visual Studio. Then placed the dll in the c:..\project\plugins\plugin\bin\ folder (at the same place as the _TemplatePlugin.dll file but with the plugins name) All i get from running the application is "Could not create instance of plugin class: Moxiecode.Manager.Plugins.Plugin" What is it I'm missing? All the other plugins ain't giving this error and they follow the same structure as my custom plugin. Thanks in advance //Micael

• Storyboard elements are not sized properly on the device

  - by Joel Fischer

  In the storyboard, I am placing a table view element into a subclassed UIView. The element is not appearing on the iPad device I am running it on the same as it appears in the storyboard however. This also happens for additional content that I place into the storyboard. Below is a screenshot as it appears in the storyboard, as well as UI width/height information. And here is the description of the UI file running on the iPad. https://gist.github.com/4323186 (embedding it directly into the post is giving me problems) You'll notice that the tableview is explicitly set at 178 width, and is showing up in the description as 276 width. My initial thought was that perhaps a cell was forcing the parent to be larger (I'm very new to iOS UI development), but drilling into that shows the prototype cell it appears that the width is defined by it's parent at 178. The image views and label also are appearing in the incorrect spot, as shown in the second image below.

• Functions as pointers in Objective-C

  - by richman0829

  This is a question from Learn Objective-C on the Mac... Functions as pointers What I typed in, as per the recipe, was: NSString *boolString (BOOL yesNo) { if (yesNo) { return (@"YES"); } else { return (@"NO"); } } // boolString The pointer asterisk in the first line doesn't seem necessary, yet deleting it results in an error message. But what does it do? In NSString * boolString (yesNo); what seems to be going on is a function is defined as a pointer to an NSString. The function without the asterisk NSLog (@"are %d and %d different? %@", 5, 5, boolString(areTheyDifferent)); returns an NSString of YES or NO. But how can it return an NSString when it's a pointer? It might return the ADDRESS of an NSString; or if dereferenced it could return the CONTENTS of that address (an NSString such as YES or NO). Yet I see no place where it is dereferenced.

• Dataset field DBNull -> int?

  - by BobClegg

  SQLServer int field. Value sometimes null. DataAdapter fills dataset OK and can display data in DatagridView OK. When trying to retrieve the data programmatically from the dataset the Dataset field retrieval code throws a StronglyTypedException error. [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] public int curr_reading { get { try { return ((int)(this[this.tableHistory.curr_readingColumn])); } catch (global::System.InvalidCastException e) { throw new global::System.Data.StrongTypingException("The value for column \'curr_reading\' in table \'History\' is DBNull.", e); } Got past this by checking for DBNull in the get accessor and returning null but... When the dataset structure is modified (Still developing) my changes (unsurprisingly) are gone. What is the best way to handle this situation? It seems I am stuck with dealing with it at the dataset level. Is there some sort of attribute that can tell the auto code generator to leave the changes in place?

• Jquery display image problem

  - by Sergio

  Hello, I have PHP page where users can upload photos (using Ajax & PHP script). Those uploaded photos (thumbs) are shown after upload in DIV below upload field. Then, after hitting send button I want to clone that DIV at that same page at message board, bellow other messages with or without uploaded photos. When I try to do that with: var pht = $("#photos").clone().addClass('p_pht'); and try to display sent photos bellow sent message like this: $("div#wall").append('<div class=msg>'+ message +'</div><div class=n_pht>'+ pht +'</div>'); I get Jquery error message "[object Object]" in place where the photos should be displaying. What am I doing wrong?

• Admin interface in Rails

  - by yuval

  I have an admin controller located in controllers/admin/admin_controller.rb I also have a pages controller located in controllers/admin/pages_controller.rb pages_controller.rb inherits from admin_controller.rb in routes.rb, I have an admin namespace as such: map.namespace :admin do |admin| admin.resources :pages end I want the admin have basic CRUD functionality in pages_controller.rb (I know how to do that) I want the index and show methods to be available to front-end users I would like the show and index actions to use separate views, but the same code. Questions: Should I create a new pages_controller for the front-end, or share the methods index and show? If share, how would I display separate views depending on whether the url is /admin/pages or /pages If share, should I place pages_controller in /controllers/admin (where it is now) or just in /controllers? Thank you very much.

• iPhone SDK: am I still allowed to develop with SDK 3.1.3 on Leopard?

  - by BoltClock

  Mac OS X Snow Leopard's been in stores for a while now. Sadly, the Mac that I'll be developing on is still running Leopard, and I don't have admin access to the Mac either so I can't do anything about the OS version. Therefore I can only use iPhone SDK 3.1.3, which we've obtained thanks to this answer, to start building apps on that Mac. Am I still allowed to develop apps with this setup and deploy for iPhone OS 3.x to the App Store? Keyword is allowed because all I've seen so far are technical questions/answers, but I'm not certain if Apple's going to be a jerk and shun me because I can't use a Snow Leopard Mac despite having only started this year (and I don't even want to get started about iPhone SDK 4's revised agreement, not with its NDA still in place...).

• What is better, a STL list or a STL Map for 20 entries, considering order of insertion is as importa

  - by Abhijeet

  I have the following scenario.The implementation is required for a real time application. 1)I need to store at max 20 entries in a container(STL Map, STL List etc). 2)If a new entry comes and 20 entries are already present i have to overwrite the oldest entry with the new entry. Considering point 2, i feel if the container is full (Max 20 entries) 'list' is the best bet as i can always remove the first entry in the list and add the new one at last (push_back). However, search won't be as efficient. For only 20 entries, does it really make a big difference in terms of searching efficiency if i use a list in place of a map? Also considering the cost of insertion in map i feel i should go for a list? Could you please tell what is a better bet for me ?

• android : how to run a shell command from within code

  - by ee3509

  I am trying to execute a command from within my code, the command is "echo 125 /sys/devices/platform/flashlight.0/leds/flashlight/brightness" and I can run it without problems from adb shell I am using Runtime class to execute it : Runtime.getRuntime().exec("echo 125 > /sys/devices/platform/flashlight.0/leds/flashlight/brightness"); However I get a permissions error since I am not supposed to access the sys directory. I have also tried to place the command in a String[] just in case spaces caused a problem but it didn't make much differense. Does anyone know any workaround for this ?

• Get UPN or email for logged in user in a .NET web application

  - by DrStalker

  I'm not a .NET developer, and I have a feeling this would be trivial for someone who is: I have a C# web application that makes user of the user credentials of the logged in user. Currently it uses the SID which comes from System.Security.Principal.WindowsIdentity.GetCurrent().User.Value I need to get either the users UPN login or email address (as defined in active directory) instead of the SID. GetCurrent() returns an object of type WindowsIdentity; looking in the details for WindowsIdentity Members: MSDN: WindowsIdentity Members I can't see anything that looks like it would give me either the UPN or email in there. How can I pull up that information to use, either by feeding the SID into some other function or calling something different in the first place.

• Hibernate configuration files not found by Axis2

  - by DanJo519

  I am writing a web service to be deployed on Tomcat using Axis2. I am using Hibernate3 to persist data between the web service and a MySQL database. When running the application through by IDE, the method I am exposing through Axis2 works as intended, however when I deploy the .aar to Tomcat, I receive a SOAP Error claiming that hibernate.cfg.xml cannot be found. However, inside the .aar, I clearly see that all the configuration file and all the mapping files are included. I have determined a workaround: If I place the resulting files from the Netbeans build/class folder into the axis2/WEB-INF/class folder, then the application works as expected. My question, then, is is there a better way to deploy my application so that Axis2 will pick up the configuration and mapping files through the deployed .aar without my manually having to copy the contents of the build/class folder into the axis2/WEB-INF/class folder?

• Java Inter Application Form Communication Observer Pattern

  - by ikurtz

  Observer pattern? Where do i get examples of this in Java (i know google but was hoping for some personal insight also.) On to a proper explanation of my issue: i have 3 forms/windows. "board" is the main form that loads as the application. "chat" is where the text chat takes place. "network" is where network connection is established. i have the game (connect4) working locally and i would like to implement a networked version of it also. my idea is maybe it is related to Observer pattern to have a thread (or something) monitoring network state during runtime and update the chat and board forms of the current network status as well as delivering received data from the network. are my ideas valid? or how should i go about establishing network and network status updates throughout the application? thank you for your input.

• Free internet radio station server software with remote broadcasting?

  - by Zachary Brown

  I am in the process of creating an internet radio station, but the two djs I have for it are not able to be in one place. I need for them to be able to login to a web based broadcasting session that still has full functionality. They need to be able to broadcast thier live shows with talk and music. The music will be stroed on the server. I have checked out the Broadwave media streaming server from NCH, but ti does not have the ability to login as a dj from a remote computer. I don't have any money for this, so I need it to be free. If this is not possible, I need it to be cheap!

• is it possible to achieve an image clipping/masking effect with html + css3?

  - by sa125

  Hi - I'm trying to place a nice border around an image that's 250x250, using only html and css. The markup is this: <div id="img-container"><img src="pic.jpg" border="0"/></div> And the css is: #img-container { height: 225px; width: 225px; padding: 3px; border: 1px solid black; z-index: 10; position: relative; overflow: hidden; border-radius: 10px; } #img-container img { z-index: 5; } Basically, I want the div container to clip the picture's edges that exceed its boundaries. This will achieve the rounded edges effect using the border-radius property (-moz-border-radius, -webkit-border-radius, etc) - if it actually works or could even be done. Looking for tips and tricks on this. Thanks. And, yes, I'm obviously not a web designer :)

• how to move and print squares visited by a knight in following order?

  - by josh kant

  Lets say you have a 5/5 board and you place and the knight started moving form the middle square. Every time knight moves it has to follow the following pattern. its easy if you draw what i mean. I am trying to code for the possible moves and print out the no. of moves in the nXn (in this case 5X5) board. The print out should be the no. of order in which the knight moved. { //move 1 //2 squares up and 1 to the left //move 2 //2 squares up and 1 to the right //move 3 //1 square up and 2 to the right //move 4 //1 square down and 2 to the right //move 5 //2 squares down and 1 to the right //move 6 //2 squares down and 1 to the left //move 7 //1 square down and 2 to the left //move 8 //one square up and 2 to the left } Any help would be appreciated. Thank you in advance..

• Anyone use Distributed VCS in a corporate environment?

  - by Eddie Parker

  I'm curious to hear about people's experiences with distributed version control in a corporate environment. Specifically: Was it difficult to gain adoption? Now that it's in place, is it well liked? What 'model' are you using (hub & spoke? Something else?) Allowing you use hub & spoke, are there any discipline problems with pushing to a central server? I'd like to hear if anyone has non-programmers working within this environment, preferably artists and the like to whom VCS can be a bit daunting. Did it work out for them?

• What operating systems available for an 8-bit microprocessor?

  - by Benoit

  It does not need to be a full fledged OS, but at least have multitasking capabilities (i.e. a scheduler). Please mention what processor architecture it works on. This is a survey, so exact capabilities are not really important. Think of this as being a place to look at for possibilities when your next 8-bit embedded project comes up... I realize that most 8-bit micro do not require an OS, but just as a counter-example, Rabbit Semiconductor offers the RCM3710 processor module with 4 serial ports, a 10-BaseT ethernet port, 512K RAM and 512K Flash. All that for $39. All based around an 8-bit Z80 core. 8-bit does NOT necessarily mean extreme resource constraint.

  - by Abs

  Hello all, I hope I can give feedback like this. It may be just me and others may have already suggested this but is there a way to view our recent comments in our account profiles? I mean I can see questions asked, questions answered etc. But there are loads of questions where I add a comment to the question asker and when I leave the site, I either have to remember what the question was to go back and check if anyone has posted anything. Simply, I think having a place where we can view our latest comments if not all our comments in the control panel/user area would be great! Thanks all

• Teradata equivalent of persisted computed column (in SQL Server)

  - by Cade Roux

  We have a few tables with persisted computed columns in SQL Server. Is there an equivalent of this in Teradata? And, if so, what is the syntax and are there any limitations? The particular computed columns I am looking at conform some account numbers by removing leading zeros - an index is also created on this conformed account number: ACCT_NUM_std AS ISNULL(CONVERT(varchar(39), SUBSTRING(LTRIM(RTRIM([ACCT_NUM])), PATINDEX('%[^0]%', LTRIM(RTRIM([ACCT_NUM])) + '.' ), LEN(LTRIM(RTRIM([ACCT_NUM]))) ) ), '' ) PERSISTED With the Teradata TRIM function, the trimming part would be a little simpler: ACCT_NUM_std AS COALESCE(CAST(TRIM(LEADING '0' FROM TRIM(BOTH FROM ACCT_NUM))) AS varchar(39)), '' ) I guess I could just make this a normal column and put the code to standardize the account numbers in all the processes which insert into the table. We did this to put the standardization code in one place.

• Using my cell phone as remote control for PC via Bluetooth/Java

  - by Jan Kuboschek

  I've got a PC and a Samsung Eternity (that's a cell phone). I'd like to use my Eternity as remote control for my PC. Here's how I think I have to go about it: Write a desktop app (server) that accepts a connection from my cell. Write an app (client) for my cell through which I can establish a connection to the server and send commands to it. The server then executes the commands (e.g. adjust volume, pause/resume movie) Thoughts on that? Spot on or way off? Regarding the Eternity: What's a good way to get started with that? I'm guessing that I'll have to get the SDK. Does anyone have a good place to start/tutorial for that? Regarding the server: Does Java come with Bluetooth connectivity straight out of the box or do I need to fetch a library for that from somewhere? If so, from where? All help is much appreciated :)
