• JQGRID Master detail on different pages

  - by dennisg

  Hello, I need some help on next things. I was trying to do next few things. I have one grid_test.php (that creates jqgrid) and index_grid.php (just to display grid.php). jQGrid in grid.php have custom button named 'Prikazi'. I want the user to select one row from that grid and when press custom button 'Prikazi' to redirect to another page to show subgrid (and to pass parameter which is the id of the selected row). Subgrid is in the file detail_test.php and also I have file called index_detail.php (for displaying the file detail_test.php with jqgrid). These php files communicate by passing parameter id_reda (or id) that is id of the selected row in grid_test.php. I have tried many ways to achieve that but I wasn't able. Subgrid php file (detail_test.php) receives that parameter but when I add that to sql statement in subgrid file it shows next error: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LIMIT 0, 0' at line 16' in C:\Zend\Apache2\htdocs\jqSuitePHP3811SourceRadna\php\jqGridPdo.php:62 I really don't know what am I doing wrong. Maybe the passing of parameter is wrong and maybe subgrid can't create colModel properly. Or it has something to do with sql statements. Actually my work was based on one of your examples masterdetail, but I wanted to have master grid on one page and when user clicks custom button, goes to another page with detail grid. You can see my example on next page: http://pljevlja.org/grid/index_test.php. And all my php files are here: -http://pljevlja.org/grid/TXT.zip<- Thanks in advance,

• Make seems to think a prerequisite is an intermediate file, removes it

  - by James

  For starters, this exercise in GNU make was admittedly just that: an exercise rather than a practicality, since a simple bash script would have sufficed. However, it brought up interesting behavior I don't quite understand. I've written a seemingly simple Makefile to handle generation of SSL key/cert pairs as necessary for MySQL. My goal was for make <name> to result in <name>-key.pem, <name>-cert.pem, and any other necessary files (specifically, the CA pair if any of it is missing or needs updating, which leads into another interesting follow-up exercise of handling reverse deps to reissue any certs that had been signed by a missing/updated CA cert). After executing all rules as expected, make seems to be too aggressive at identifying intermediate files for removal; it removes a file I thought would be "safe" since it should have been generated as a prereq to the main rule I'm invoking. (Humbly translated, I likely have misinterpreted make's documented behavior to suit my expectation, but don't understand how. ;-) Edited (thanks, Chris!) Adding %-cert.pem to .PRECIOUS does, of course, prevent the deletion. (I had been using the wrong syntax.) Makefile: OPENSSL = /usr/bin/openssl # Corrected, thanks Chris! .PHONY: clean default: ca clean: rm -I *.pem %: %-key.pem %-cert.pem @# Placeholder (to make this implicit create a rule and not cancel one) Makefile: @# Prevent the catch-all from matching Makefile ca-cert.pem: ca-key.pem $(OPENSSL) req -new -x509 -nodes -days 1000 -key ca-key.pem $@ %-key.pem: $(OPENSSL) genrsa 2048 $@ %-cert.pem: %-csr.pem ca-cert.pem ca-key.pem $(OPENSSL) x509 -req -in $ $@ Output: $ make host1 /usr/bin/openssl genrsa 2048 ca-key.pem /usr/bin/openssl req -new -x509 -nodes -days 1000 -key ca-key.pem ca-cert.pem /usr/bin/openssl genrsa 2048 host1-key.pem /usr/bin/openssl req -new -days 1000 -nodes -key host1-key.pem host1-csr.pem /usr/bin/openssl x509 -req -in host1-csr.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 host1-cert.pem rm host1-csr.pem host1-cert.pem This is driving me crazy, and I'll happily try any suggestions and post results. If I'm just totally noobing out on this one, feel free to jibe away. You can't possibly hurt my feelings. :)

• Modify Executing Jar file

  - by pinkynobrain

  Hello Stack Overflow friends. I have a simple problem which i fear doesnt have a simple solution and i need advice as to how to proceed. I am developing a java application packaged as and executable JAR but it requires to modify some of its JAR file contents during execution. At this stage i hit a problem because some OS lock the file preventing writes to it. It is essential that the user sees an updated version of the jar file by the time the application exits allthough i can be pretty flexible as to how to achieve this. A clean and efficient solution is obviously prefereable but portability is the only hard requirement. The following are three approaches i can see to solving the problem, feel free to comment on them or suggest others. Tell Java to unlock the JAR file for writing(this doesnt seem possible but it would be the easyest solution) Copy the executable class files to a tempory file on application startup, use a class loader to load these files and unload the ones from the initial JAR file.(Not had much experience with the classloaders but hopefully the JVM would then be smart enough to realize that the original JAR is nolonger in use and so unlock it) Put a Second executable JAR File inside the First, on startup extract the inner jar to e temporaryfile, invoke a new java process and pass it the location of the Outer JAR, first process exits, second process modifys the Outer jar unincumbered.(This will work but im not sure there is a platform independant way of one java app invoking another) I know this is a weird question but any help would be appreciated.

• Suppress Eclipse compiler errors in in a plug-in

  - by Jan Gorzny

  Hi, I'm currently working on a plug-in for Eclipse that translates some custom Java code (which doesn't necessarily run/compile), to runnable Java code. In particular, the plug-in allows code to be written using classes created or imported during the translation. In general, the pre-translation code runs/compiles fine provided the writer uses import statements at the top of their class files. However, it would be convenient for my users if it was not necessary to import these classes. At the moment, the lack of import statements results in (obvious) compiler errors. Would it be possible to empower my plug-in to either a) suppress/ignore these errors, or b) have Eclipse find these classes automatically, without the use of import statements? I should point out that the translated code would these include the required import statements--but this is not a problem for me. I'm also aware that this could lead to lazy programmers and some bad habits. To clarify, consider the following example of pre-translated code: File f = new File("Somefilename.txt"); which clearly requires the possibly imported class File. Without an import statement (import java.io.File;), Eclipse reports that File can not be resolved to a type. This is the error I'd like to hide in files pertaining to projects created for use with my plug-in. (The translated code would include import java.io.File; so that it would be runnable) In closing, I should point out I'm not necessarily looking for code (though I wouldn't be opposed to it), but rather some links to some relevant tutorials (if they exist), or helpful tips/ideas. Also, as this is my first plug-in, it's entirely possible that what I'd like to do is not possible and that I don't realize it--if this is the case, please let me know, preferably with some justification. Thanks!

• JSF and CXF not working together

  - by Milan

  I want to make dynamic web service invoker in JSF with CXF. But when I load this simple code I get error. The code: JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance(); Client client = dcf.createClient("http://ws.strikeiron.com/IPLookup2?wsdl"); The error: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions! If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml. A typical config looks like this; org.apache.myfaces.webapp.StartupServletContextListener Caused by: java.lang.IllegalStateException - No Factories configured for this Application.

• Why is my GZipStream not writeable?

  - by Ozzah

  I have some GZ compressed resources in my program and I need to be able to write them out to temporary files for use. I wrote the following function to write the files out and return true on success or false on failure. In addition, I've put a try/catch in there which shows a MessageBox in the event of an error: private static bool extractCompressedResource(byte[] resource, string path) { try { using (MemoryStream ms = new MemoryStream(resource)) { using (FileStream fs = new FileStream(path, FileMode.Create, FileAccess.ReadWrite)) { using (GZipStream zs = new GZipStream(fs, CompressionMode.Decompress)) { ms.CopyTo(zs); // Throws exception zs.Close(); ms.Close(); } } } } catch (Exception ex) { MessageBox.Show(ex.Message); // Stream is not writeable return false; } return true; } I've put a comment on the line which throws the exception. If I put a breakpoint on that line and take a look inside the GZipStream then I can see that it's not writeable (which is what's causing the problem). Am I doing something wrong, or is this a limitation of the GZipStream class?

• Programmatically open an email from a POP3 and extract an attachment

  - by Josh

  We have a vendor that sends CSV files as email attachments. These CSV files contain statuses that are imported into our application. I'm trying to automate the process end-to-end, but it currently depends on someone opening an email, saving the attachment to a server share, so the application can use the file. Since I cannot convince the vendor to change their process, such as offering an FTP location or a Web Service, I'm stuck with trying to automate the existing process. Does anyone know of a way to programmatically open an email from a POP3 account and extract an attachment? The preferred solution would reside on a Windows 2003 server, be written VB.NET and secure. The application can reside on the same server as the POP3 server, for example, we could setup the free POP3 server that comes with Windows Server and pull against the mail file stored on the file system. BTW, we are willing to pay for an off-the-shelf solution, if one exists. Note: I did look at this question but the answer points to a CodeProject solution that doesn't deal with attachments.

• How can I add the "--watch" flag to this TextMate snippet?

  - by Jannis

  I love TextMate as my editor for all things web, and so I'd like to use a snippet to use it with style.less files to automatically take advantage of the .less way of compiling .css files on the fly using the native $ lessc {filepath} --watch as suggested in the less documentation (link) My (thanks to someone who wrote the LESS TM Bundle!) current TextMate snippet works well for writing the currently opened .less file to the .css file but I'd like to take advantage of the --watch parameter so that every change to the .less file gets automatically compiled into the .css file. This works well when using the Terminal command line for it, so I am sure it must be possible to use it in an adapted version of the current LESS Command for TextMate since that only invokes the command to compile the file. So how do I add the --watch flag to this command:? #!/usr/bin/env ruby file = STDIN.read[/lessc: ([^*]+\.less)/, 1] || ENV["TM_FILEPATH"] system("lessc \"#{file}\"") I assume it should be something like: #!/usr/bin/env ruby file = STDIN.read[/lessc: ([^*]+\.less)/, 1] || ENV["TM_FILEPATH"] system("lessc \"#{file}\" --watch") But doing so only crashes the TextMate.app. Any ideas would be much appreciated. Thanks for reading. Jannis

• Vista 64-bits development tools

  - by Workshop Alex

  Well, okay. There's Visual Studio 2008 and Embarcadero Delphi/Studio that are both able to create 64-bits .NET applications for Vista. And of course a lot of 32-bits applications will run on 64-bits Vista. If not, it's always possible to install VMWare to create a virtual 32-bits Windows XP system to run 32-bits applications. So, plenty of options. But what I would like to see is a list of true 64-bits applications for Windows Vista and better. So if you know any useful 64-bits product, please share! (Especially compilers that generate native 64-bits code.) Tools would basically be anything that would make development a bit easier. Thus, debugging tools, image processing tools to create icons and bitmaps, hex editors to check the contents of binary files, XML editors to change XML files, etc. The tools from SysInternals, for example, seem to provide 64-bits versions or even support 64-bits systems natively. But how about all those other editors, viewers, browsers and other tools that we developers like to use? A 64-bits version of the Norton Commander/Midnight Commander or other file managers would be nice too. And with compilers, how about COBOL/ForTran/ADA/SmallTalk/Lisp/Whatever compiler/languages for Vista? I would just like to see a complete list of anything useful for 64-bits development.

• why is the <img> alt attribute not always properly displayed

  - by Piero

  So I have this php script that output an html table with data about some files (like filename, filesize, etc...) I have this javascript function that displays the picture when you hover a tag belonging to the class "preview". For example, if a filename is: somePic.jpg, when you hover somePic.jpg in the table, the picture will appear next to your mouse. Now not all these files are pictures, some are .mp3, so of course when you hover them, the javascript cannot display the picture. To deal with this case, I added in the tag (generated by the javascript function), an alt attribute: alt='Preview not available for this type of content.' And here is my problem, sometimes it works, but sometimes it doesn't! Sometimes you start hovering .mp3 links, and the alt attribute is displayed, then you hover a picture, the picture is displayed, then you hover an .mp3 again, and the alt isn't displayed anymore, but the "broken image" image (the little red cross) is displayed instead... Sure I could parse the filenames and detect when it's an mp3 and then deal with the case, but I thought the alt attribute was suppose to achieve this... but it's buggy... Any idea? Does anyone already faced this problem?

• Strange MSI error when setup.exe is run

  - by Martin Jackson

  We're using Visual Studio 2008's Setup Project to create an installer for our .NET 3.5 app. We host the .exe and .msi files on a website for our client to access, and produce new ones regularly to provide updates. This has all been fine until recently we've noticed some cases where installing via the .exe fails. The symptoms are: The .exe downloads fine, and runs fine. It appears to download the .msi successfully (the "downloading application files" step plods through happily), but then when it gets to the end of the "preparing to install" step, instead of launching the installer UI it pops up a message saying "This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package". You'd think that the .msi is just corrupt or something, but running it explicitly (even downloading it from the same location as the .exe to do so) works just fine. This problem is occurring on just some of our machines, which are running a mixture of XP and Windows7. The only pattern I can see in those machines that experience the problem is that they tend to have had the application installed on them longer (i.e. updating the app rather than installing for the first time). It seems to me that it might be something to do with how/where the .exe downloads the .msi to, and perhaps different versions are conflicting there? Has anyone experienced this before? Does anyone know where the installer .exe puts the .msi that it downloads?

• Visual Studio 2008 IDE freezes/crashes when opening .aspx file with css included

  - by Kai

  I have read a lot of questions about Visual Studio 2008 crashing on viewing some source files. However, I still can't fix this problem. Visual Studio (SP1) runs fine until I try and view .aspx source files with the lines <style type="text/css"> </stlye> anywhere in them, upon which it freezes (i.e is totally unresponsive) and I have to use the task manager to shut it down. I have systematically deleted and re-included all other code and it comes down to these two lines, which is very confusing. Sometimes it happens as soon as the lines are added, sometimes it doesn't freeze until I build the solution with any of the problem pages open. I can add external style sheets, and it only started recently. I tried the event viewer logs but I don't really understand how to use them to find out about this. I had Resharper 4.5 installed and have since uninstalled it, and do not have anything else installed. Is there any way I can a) find out what's happening, b) fix it without reinstalling vs?

• PHP site keeps opening to blank page, no errors.

  - by gene

  First, the premises: PHP loaded on IIS6 on Win2003 STD R2 SP2, PHP_5213 using FastCGI, MySQL_5145. Customer sent me the site files, which I unzipped to C:\InetPub\wwwroot\<site root>, then I created a new site in IIS, pointed to <site root>, added test.php to the site files for testing and it works, but visiting index.php produces a blank page with no errors. The readme.txt file present makes reference to application.php and explains root folder var and sets it to a non-existent file. I don't know PHP syntax, but I tried several logical changes with zero results. At this point I'm not even sure if that is the problem anymore. With PHP, MySQL & site debugging have put in over 20 hours. Still confused, I have resorted to heavy drug use and purchased a small firearm, loaded with a single round (even this seemed to take an inordinate amount of time). I've given up all hope. Someone please help save a new server and/or old administrator.

• Basic Subversion questions

  - by Epitaph

  I've just started using subversion, and have read the official documentation (svn book), cheat sheet and a couple of guides. I know how to install subversion (in linux), create a repository (svnadmin create), and import my Eclipse project into the repository (SVN import), view the repository files (using svn list). But I am unable to understand some of the other terminologies. For example, after importing my Eclipse project into the newly created repository I have made changes to my Eclipse project (more than 1 file). Now, how should I update the repository with this added files/changes made to my Eclipse project? The svn update command brings the changes from the repository into your working copy - which is the opposite of what I want i.e. bring the changes I made in my Eclipse project into the previously imported project in repository. If I am correct, you update the repository more often (as you keep extending your project implementation) than your current project (with update). Also, I do not understand when would you use svn merge. The svn book states it applies the differences between 2 sources to a working copy. Is there a scenario which would explain this? Finally, can I have more than 1 project checked into the repository? Or is it better to create a new repository for each project?

• Python Django Global Variables

  - by Joe J

  Hi all, I'm looking for simple but recommended way in Django to store a variable in memory only. When Apache restarts or the Django development server restarts, the variable is reset back to 0. More specifically, I want to count how many times a particular action takes place on each model instance (database record), but for performance reasons, I don't want to store these counts in the database. I don't care if the counts disappear after a server restart. But as long as the server is up, I want these counts to be consistent between the Django shell and the web interface, and I want to be able to return how many times the action has taken place on each model instance. I don't want the variables to be associated with a user or session because I might want to return these counts without being logged in (and I want the counts to be consistent no matter what user is logged in). Am I describing a global variable? If so, how do I use one in Django? I've noticed the files like the urls.py, settings.py and models.py seems to be parsed only once per server startup (by contrast to the views.py which seems to be parsed eache time a request is made). Does this mean I should declare my variables in one of those files? Or should I store it in a model attribute somehow (as long as it sticks around for as long as the server is running)? This is probably an easy question, but I'm just not sure how it's done in Django. Any comments or advice is much appreciated. Thanks, Joe

• python __import__() imports from 2 different directories when same module exists in 2 locations

  - by programer_gramer

  Hi, I have a python application , which has directory structure like this. -pythonapp -mainpython.py -module1 -submodule1 -file1.py -file2.py -submodule2 -file3.py -file3.py -submodule3 -file1.py -file2.py -file5.py -file6.py -file7.py when I try to import the python utilities(from mainpython.py) under submodule3 , I get the initial 2 files from submodule1.(please note that submodule1 and 3 have 2 different files with the same name). However the same import works fine when there is no conflict i.e it correctly imports file 5,6,7 from submodule3. Here is the code : name=os.path.splitext(os.path.split("module1\submodule3\file1.py")[1])[0] -- file1.py name here is passed dynamically. module = import(name) //Here is name is like "file1" it works(but with the above said issue, though, when passes the name of the file dynamically), but if I pass complete package as "module1.submodule1.file1" it fails with an ImportError saying that "no module with name file1" Now the question is how do we tell the interpreter to use only the ones under "module1.submodule3.file2"? I am using python This is really urgent one and I have run out of all the tries. Hope some experienced python developers can solve this for me?

• Object created in Interface Builder getting dealloc'ed too soon

  - by Collin Allen

  The Project I'm working on a relatively simple iPhone OS project that's navigation controller based, with a root table view and a detail table view. Tap an item in the main list to see its details in a pushed table view. The Setup I broke out the data source for both views into their own objects so as not to muddy the purpose of a view controller. Having done this, the table views no longer have data sources since those methods are now in separate files, so I created an instance of each data source class in the appropriate XIB files with the Object item (dragged it in, then set its class). Then, to actually connect the tableviews to their data sources, I set the dataSource outlet of each tableview to the yellow data source object in Interface Builder. The table view delegates are still set to their view controllers. The Problem The root table view works just fine, but when you tap a row to push to the detail view, the data source object gets instantiated as expected, then immediately dealloc'ed, causing a crash (numberOfSectionsInTableView: gets called on the freed object). I can't figure out why the data source is getting automatically dealloc-ed when I need it right then and there for the detail view, as indicated by my data source object creation and tableview connection in Interface Builder. What's more perplexing is that the very approach works fine for the root tableview! The Question Is there anything obvious I'm missing that would cause this to happen? Or, is this even the right way to instantiate a data source for a table view controller? It seems like poor object oriented programming to do it from within the view controller, which should only be concerned with the view. I could cram everything in two table view controller classes and it would probably work, but it would not be as modular as I'd like. Thanks!

• Is there any way to combine transparency and "ajax usability" with HTML templates

  - by Sam

  I'm using HTML_Template_Flexy in PHP but the question should apply to any language or template library. I am outputting a list of relatively complex objects. In the beginning I just iterated over a list of the objects and called a toHtml method on them. When I was about to have my layout designer look over the template I noticed that it was too opaque and that he would have ended up looking through and/or editing many additional php source files to see what really gets generated by the toHtml method. So I extracted most of the HTML strings in the php classes up to the template which made for one clear file where you can see the whole page structure at once. However this causes problems when you want to add an object to the list using javascript. Then I have to keep the old toHtml method and maintain both the main template and the html strings at the same time, so I can output just the HTML for a new object that should be added to the page. So I'm back to the idea of using smaller templates for the objects that make up the page, but I was wondering if there was some easy way of having my cake and eating it too by having one template that shows the whole page but also the mini-templates for smaller objects on the page. Edit: Yes, updating the page is not a problem at all. My concern is with having both maintainability and transparency of the template files. If I have one single template for the whole page, then I must maintain mini-templates of the objects that are shown on the page. If I just have the mini-templates and include them from the higher-level template it becomes more difficult to look at the top-level html and imagine what the end result will look like.

• Create custom culture in ASP.NET

  - by Billy

  I want to create a resource file for Singaporean English (en-sg) named "shopping.en-sg.resx" in App_GlobalResources folder. I get error during compilation. Error 1 The namespace 'Resources' already contains a definition for 'shopping' c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\web\2cd6afe9\737b0a13\App_GlobalResources.vomuzavz.1.cs 26 After searching Google, I discover that "en-sg" is not a default culture and I have to create custom culture for it. I don't know the detailed steps of this. What should I do to create the culture and remove the compilation error? I follow the example in MSDN, create a file called "shopping.x-en-US-sample.resx" and put the following code into BasePage's function (protected override void InitializeCulture()): CultureAndRegionInfoBuilder cib = null; cib = new CultureAndRegionInfoBuilder( "x-en-US-sample", CultureAndRegionModifiers.None); CultureInfo ci = new CultureInfo("en-US"); cib.LoadDataFromCultureInfo(ci); RegionInfo ri = new RegionInfo("US"); cib.LoadDataFromRegionInfo(ri); cib.Register(); ci = new CultureInfo("x-en-US-sample"); However, compilation error is still exist. UPDATED: You can easily reproduce the problem by creating an empty website and two files "shopping.en-sg.resx" and "shopping.resx" in the app_globalresources folder.

• How to avoid chaotic ASP.NET web application deployment?

  - by emzero

  Ok, so here's the thing. I'm developing an existing (it started being an ASP classic app, so you can imagine :P) web application under ASP.NET 4.0 and SQLServer 2005. We are 4 developers using local instances of SQL Server 2005 Express, having the source-code and the Visual Studio database project This webapp has several "universes" (that's how we call it). Every universe has its own database (currently on the same server) but they all share the same schema (tables, sprocs, etc) and the same source/site code. So manually deploying is really annoying, because I have to deploy the source code and then run the sql scripts manually on each database. I know that manual deploying can cause problems, so I'm looking for a way of automating it. We've recently created a Visual Studio Database Project to manage the schema and generate the diff-schema scripts with different targets. I don't have idea how to put the pieces together I would like to: Have a way to make a "sync" deploy to a target server (thanksfully I have full RDC access to the servers so I can install things if required). With "sync" deploy I mean that I don't want to fully deploy the whole application, because it has lots of files and I just want to deploy those new or changed. Generate diff-sql update scripts for every database target and combine it to just 1 script. For this I should have some list of the databases names somewhere. Copy the site files and executing the generated sql script in an easy and automated way. I've read about MSBuild, MS WebDeploy, NAnt, etc. But I don't really know where to start and I really want to get rid of this manual deploy. If there is a better and easier way of doing it than what I enumerated, I'll be pleased to read your option. I know this is not a very specific question but I've googled a lot about it and it seems I cannot figure out how to do it. I've never used any automation tool to deploy. Any help will be really appreciated, Thank you all, Regards

• EDIT Control Showing Squares Instead Of Returns

  - by Nathan Campos

  I'm playing a little bit with PocketC by doing a simple text editor. But with this code to read and to display the contents of the file on the EDIT control: int filehandle; int file_len; string file_mode; initComponents() { createctrl("EDIT", "test", 2, 1, 0, 24, 70, 25, TEXTBOX); wndshow(TEXTBOX, SW_SHOW); guigetfocus(); } main() { filehandle = fileopen(OpenFileDlg("Plain Text Files (*.txt)|*.txt; All Files (*.*)|*.*"), 0, FILE_READWRITE); file_len = filegetlen(filehandle); if(filehandle == -1) { MessageBox("File Could Not Be Found!", "Error", 3, 1); } initComponents(); editset(TEXTBOX, fileread(filehandle, file_len)); } It's all ok, but my test file, now have returns: Hello, World! PocketC Test Of My Editor Then when I open this file on the editor, instead of returns, I just see two squares(that means that it's a unknown character for that control), but if I change the control to a STATIC, it does he returns ok, but I can't edit the text if I use a STATIC. Then I want to know what I need to do to do the returns instead of showing those squares.

• iPhone: Proper use of View and View Controller

  - by Joel

  I've recently been doing a lot of Objective-C programming, and just got back into doing more iPhone development. I've done a lot of programming using MVC in other languages/frameworks, but I just want to make sure I'm using MVC properly in my iPhone Development. I created a new iPhone Utility Application, which creates two views: MainView and FlipsideView. Both have a controller (FlipsideViewController and MainViewController) and XIB file of their own. What I've been doing is putting the IBOutlet UIControl myControl variables in my MainView.h or FlipsideView.h files and then tying the controls in Interface Builder to those variables. Then I put any IBAction SomeAction myAction methods in the MainViewController.h and FlipsideViewController.h files and tying the events to those methods in Interface Builder. This seems to be conceptually correct, but seems to cause problems. Say I have a button that when clicked it changes a label's text. So the Controller doesn't have a clue of what the variable name of the label is in the OnTouchUp event handler for my button. So I make a @property for it. But since the MainViewController.view property isn't of type MyView, I get warnings or errors whenever I try to access those properties from the view controller. I am doing this correctly? Is there a better way to do this? If this is correct, how do I properly work with those variables without getting warnings or errors? Thanks

• Is there a Standard or Best Practice for Perl Progams, as opposed to Perl Modules?

  - by swestrup

  I've written any number of perl modules in the past, and more than a few stand-alone perl programs, but I've never released a multi-file perl program into the wild before. I have a perl program that is almost at the beta stage and is going to be released open source. It requires a number of data files, as well as some external perl modules -- some I've written myself, and some from CPAN -- that I'll have to bundle with it so as to ensure that someone can just download my program and install it without worrying about hunting for obscure modules. So, it sounds to me like I need to write an installer to copy all the files to standard locations so that a user can easily install everything. The trouble is, I have no idea what the standard practice would be for this. I have found lots of tutorials on perl module standards, but none on perl program standards. Does anyone have any pointers to standard paths, installation proceedures, etc, for perl programs? This is going to be complicated by the fact that the program is multi-platform. I've been testing it in Linux, but its designed to work equally well in Windows.

• Version control - stubs and mocks

  - by Tesserex

  For the sake of this question, I don't care about the difference between stubs, mocks, dummies, fakes, etc. Let's say I'm working on a project with one other person. I'm working on component A and he is working on component B. They work together, so I stub out B for testing, and he stubs out A. We're working in a DVCS, let's say Git, because that's actually the case here. When it comes time to merge our components together, we need to get the "real" files from my A and his B, but throw away all the fake stuff. During development, it's likely (unless I need to learn how to properly stub things) that the fakes have the same file names and class names as the real thing. So my question is: what is the proper procedure for doing version control on the fakes, and how are the components correctly merged, making sure to grab the real thing and not the fake? I would guess that one way is just do the merge, expect it to say CONFLICT, and then manually delete all the fake code out of the half-merged files. But this sounds tedious and inefficient. Should the fake things not go under VC at all? Should they be ripped out just before merging? Sorry if the answer to this should be obvious or trivial, I'm just looking for a "suggested practice" here.

• Rails 2.3.2 trying to render ERB instead of HAML

  - by c00lryguy

  Rails is suddenly trying to render ERB instead of Haml and I can't figure out why. I've created new rails projects, reinstalled Haml, and reinstalled Rails. Here's exactly the steps I take when making my application (Rails 2.3.2): rails> rails test rails> cd test rails\test> haml --rails . rails\test> ruby script\generate model user email:string password:string rails\test> ruby script\generate controller users index rails\test> rake db:migrate Here's what the UsersController looks like: class UsersController < ApplicationController def index @users = User.all end end My routes: ActionController::Routing::Routes.draw do |map| map.resources :users end I now create views\users\index.html.haml: %table %th(style="text-align: left;") %h1 Users - for user in @users %tr %td= user.email %td= user.password Annnd run the server... I navigate to localhost:3000\users and I get this error message: Template is missing Missing template users/index.erb in view path app/views For some reason Rails is trying to find and render .erb files instead of .haml files. vendor\plugins\haml\init.rb exists, untouched. I've reinstalled Haml (Pretty Penny) multiple times and still get the same results. I've also tried adding config.gem 'haml' to my environment.rb but this also doesn't work. I can't figure out why suddenly rails will not render haml for me.
