• JSF validateLength question

  - by user337515

  I have a input field with validation to validate the max and min length <h:inputText id="LABEL_ID" styleClass="textboxsmall" value="#{sampleDatatableBean.accessionLabelId}" maxlength="5"> <f:validateLength minimum="4" maximum="5" /> </h:inputText> <br/><h:message id="LABEL_ID_MSG" styleClass="errorMessage" for="LABEL_ID" /> It validates but I get the below message: "Value is less than allowable minimum of {0}" Shouldn't {0} be replaced by value from minimum? Not sure why its not picking up the value. Any ideas?

• Zend Studio 7.1 PHPUnit Test Case wizard does not populate "Element to Test"

  - by Mike

  When I follow the instructions in ZS documentation to create a phpunit test case, the wizard returns no objects to select on the "Element to Test" line. Selecting "browse" provides an empty dialog box. The PHPUnit path in my preferences shows "/Applications/zend/zs710/plugins/com.zend.php.phpunit_7.1.0.v20091120-0900/resources/library/". What else can I check to see why I cannot create a test case? I'm new to ZS and PHP, so I have no idea how to troubleshoot this. Thanks.

• how can I deliver remote content via web service?

  - by Slinky

  We have multiple websites under different domains that need to receive our banner ads. We have a server app, in PHP, that returns the HTML for a randomly-generated banner ad. Out of concern for the client side, I don't want to use an iframe nor do I want to include the jquery library because of the weight - I also do not want to duplicate code across all the domains. Any other way to do this? Maybe there is a way to do this with mod rewrite or a web service? Anyone solve a similar problem? Thanks

• how to call a php class function directly using ajax?

  - by payling

  Is it possible to call a php class function DIRECTLY using ajax? Something like below... except ajax... myclass::myfunction(); I've been using the jquery library to work with AJAX. $.get('control.php', {func: funcName, arg1: arg1}); The above is similar to what I'm trying to achieve MINUS the control.php; I'm not sure if this is even possible, but I just thought it would be nice to skip the landing page (control.php) that recieves the funcName. I have a bunch of conditional statements that sort out what class function to run based on the funcName recieved. It seems kind of silly to do this, to have a separate page just to handle function calls. Is there a better way?

• Generating link-time error for deprecated functions

  - by R..

  Is there a way with gcc and GNU binutils to mark some functions such that they will generate an error at link-time if used? My situation is that I have some library functions which I am not removing for the sake of compatibility with existing binaries, but I want to ensure that no newly-compiled binary tries to make use of the functions. I can't just use compile-time gcc attributes because the offending code is ignoring my headers and detecting the presence of the functions with a configure script and prototyping them itself. My goal is to generate a link-time error for the bad configure scripts so that they stop detecting the existence of the functions.

• Should the name of my classes begin with 'Q' in Qt?

  - by Venemo

  Hello Everyone, When I first started working with Qt, it was extremely annoying that every class has a name beginning with 'Q', but now I've got used to it. I'm using Qt Creator, and it highlights code quite well. However, it only highlights class names beginning with 'Q'. And it highlights everything beginning with 'Q' even if there is no such type. It doesn't highlight custom class names. That makes me wonder, should I also begin all my class names with 'Q'? Or at least the reusable ones? (I mean, those that I put in a class library, or reuse in another app.) I've seen several places where they named their classes this way. Is it a good thing? I found this page about Qt's naming conventions, but it doesn't deal with this question. Also, I don't understand why Qt doesn't use namespaces.

• How does Contract.Exists add value?

  - by Scott Bilas

  I am just starting to learn about the code contracts library that comes standard with VS2010. One thing I am running into right away is what some of the contract clauses really mean. For example, how are these two statements different? Contract.Requires(!mycollection.Any(a => a.ID == newID)); Contract.Requires(!Contract.Exists(mycollection, a => a.ID == newID)); In other words, what does Contract.Exists do in practical purposes, either for a developer using my function, or for the static code analysis system?

• MonthCalendar control selection range with EnableVisualStyles?

  - by warren_s

  I'm using the MonthCalendar control and want to programmatically select a date range. When I do so the control doesn't paint properly if Application.EnableVisualStyles() has been called. This is a known issue according to MSDN. Using the MonthCalendar with visual styles enabled will cause a selection range for the MonthCalendar control to not paint correctly (from: http://msdn.microsoft.com/en-us/library/system.windows.forms.monthcalendar.aspx) Is there really no fix for this other than not calling EnableVisualStyles? This seems to make that particular control entirely useless for a range of applications and a rather glaring oversight from my perspective.

• How can I print a text in two columns using Java Swing?

  - by Jonas

  I have a longer text saved in a String. I would like to print the text in two columns on a single page. How can I do this using Java Swing? I don't understand how I can wrap the text when it's time to use a new line. I have read Lesson: Printing in the Java tutorial, but I haven't found any useful methods for working with text or Strings except FontMetrics. Is there any good methods in the Java API for this or is there any good library I can use for this?

• Detect if an assembly is available

  - by jgaa

  I'm implementing an installer in Java, that is supposed to download and install an application for non-privileged users in Windows (from XP and up). The application is written in C++, and depend on the usual VC runtime-libraries (msvcm90.dll and friends). In order to save bandwidth, I want to avoid downloading the VC redistributables if they already are available for the user. I do however have a problem finding a reliable method to detect if an assembly is installed. If the assembly is missing, I will deploy it as described here: http://msdn.microsoft.com/en-us/library/ms235291%28VS.80%29.aspx So the question is simply how to detect if a (any) assembly is installed on the machine. It's no requirement that this can be done from Java. I can easily write a small probe in C++ and link it statically for the task. jgaa

• How to Optimize Combined Graphical Operations?

  - by Sunny

  Hi, Here is a Scenario, A series of operations that I will call for painting, QPainter p(this); 1). p.fillRect(0,0,320,240, RED_COLOR) 2) p.drawLine(0,0,100,100, BLUE_COLOR) 3) p.fillRect(0,0,320,240, YELLOW_COLOR) Now I want that painter should not draw first FillRect Function. It should not draw line. It should only perform last operation. Is there any way to achive this optimization in Qt. Is this type of drawing/painting optimizations are supported by any library?

• jquery-plugin Masonry: I cannot make it work

  - by Patrick

  hi, I'm using Masonry library (http://desandro.com/resources/jquery-masonry/) to create columns from my content. I cannot make it work.. this is the url with the html code: http://donatellabernardi.ch/drupal/ And this is my javascript line: $('#content-area').masonry({ columnWidth: 50, itemSelector:'.views-row'}); The Masonry function is invoked, but it doesn't add any column... I've also tried: $('#content-area').masonry({ columnWidth: 50, itemSelector:'.node'}); $('#content-area').masonry({ columnWidth: 50 }); $('div.view-content').masonry({ columnWidth: 50 }); What am I doing wrong ? Thanks

• How do you handle multiple (overlapping) projects in trac?

  - by Oliver Giesen

  We are using trac and are really satisfied with it. However, out of the box, trac is best suited for single-project environments only. I'd be interested to hear about the various approaches people take to make it work with multiple projects nevertheless and their experiences with them. Are there any plugins to recommend? Any patches, tweaks or whatnots? Are you maybe even using an entirely different bug-tracking system that offers all of trac's functionality plus multi-project support? We recently started managing a second project ourselves which generally works okay but also has some drawbacks, especially where the two projects overlap because of common library code we wrote that is used in both projects. How do you handle this? (I'll attach our own current approach as an answer to this post.)

• Whay types of grammar files are usable for spoken voice recognition?

  - by user1413199

  I'm using the System.Speech library in C# and I would like to create a smaller file to house commands as opposed to the default grammar. I'm not totally sure what I need. I've been looking at several different things but I don't really have any idea what I'm doing. I've read up on some stuff in ANTLR and looked at NuGram from NuEcho. I understand what a grammar file is and roughly how to create one but I'm not sure how they're used specifically for deciphering spoken words.

• Adding text labels to sliders in iPhone Settings application

  - by Kevin L.

  When configuring a Settings.bundle as part of an iPhone application bundle, it's trivial to add minimum and maximum value images to sliders (PSSliderSpecifier), but not simple maximum and minimum text labels. http://developer.apple.com/iPhone/library/documentation/PreferenceSettings/Conceptual/SettingsApplicationSchemaReference/Articles/PSSliderSpecifier.html iPhone gurus: Is anyone aware of a simple means to apply text labels to these sliders for use within the Settings application (therefore, no slider subclassing shenanigans; it all has to be done via a plist)? I suppose I could just use an image of the label but...ew. Bonus points if there's a way to show the current value of a slider in some sort of number format.

• ask. help me to compare two array of integers and the order does not matter.

  - by stdnoit

  [Example] <1 2 3 4 = <3 1 2 4 <1 2 3 4 != <3 4 1 1 and ummm it is in java. cant use hashmap table or anything just pure without library. I know there are two ways. 1. sort them and compare the array index by index 2. use two for loops and compare the outer index with the inner index. ( i have been trying with this but still not working) for(int i = 0; i < n; i++) { for(int j = 0; j < n; j++) { if(a[i] != a[j] && j == n) return false; } } return true; anything wrong with the code ? thanks

• Boost Shared Pointers and Memory Management

  - by Izza

  I began using boost rather recently and am impressed by the functionality and APIs provided. In using boost::shared_ptr, when I check the program with Valgrind, I found a considerable number of "Still reachable" memory leaks. As per the documentation of Valgrind, these are not a problem. However, since I used to use the standard C++ library only, I always made sure that any program written is completely free from memory leaks. My question is, are these memory leaks something to worry about? I tried using reset(), however it only decrements the reference count, doesn't deallocate memory. Can I safely ignore these, or any way to forcibly deallocate the memory allocated by boost::shared_ptr? Thank you.

• Getting lpfnAcceptEx (accpetex) to block in native C++

  - by Alikar

  Hello, I've been trying to get the lpfnAcceptEX function in Win32 to block on accept. If this is not possible I was wondering if there was a flag I could accpet or some other function that I could wait on. Right now the program is simply continually creating accepted sockets with no connections behind them. Perhaps I am misunderstanding how this is to work. Is there another function I need to wait on? I am following the example laid out here: http://msdn.microsoft.com/en-us/library/ms737524(VS.85).aspx Thanks, = Alikar

• What is the universal way to use file I/O API with unicode filenames?

  - by dma_k

  In Windows there is a common problem: the filenames should be converted to local codepage, before they are passed to open(). Of course, there is a possibility to use Win32::API for that, but I don't want my script to be platform-dependent. At the moment I have to write something like: open IN, "<", encode("cp1251", $filename) or die $!; but is there any library, that hides these details? I think the local codepage can be automatically detected, so I just want to pass unicode filename and forget about the details. Why is it still not in the box?

• Storing data with a stand-alone C++ application

  - by Mike

  I work with Apache, PHP, and MySQL for web development and local applications. For the past couple of years I have slowly been learning C++ and want to build an application this summer. Specifically, I want to make a "library" application in which I can store information about the books, CDs, and records that I own. I know this type of app exists, but I want to learn C++ and this seems like a good way to go about it. Here are a few questions: Is it possible to create a stand-alone application that does not require a database for storing data? If the answer to #1 above is "yes", is it a good idea to do this for an application that could potentially need to manage a lot of data? What data-storage options would you recommend for use with a C++ application? Thanks!

• Avoid stuck calling callback

  - by andlomba

  Hello all, This is a question about generic c++ event driven applications design. Lets assume that we have two threads, a "Dispatcher" (or "Engine"...) and a "Listener" (or "Client"...). Let's assume that I write the Dispatcher code, and release it as a library. I also write the Listener interface, of course. When the Dispatcher executes (after Listener registration) listenerInstance.onSomeEvent(); the event handling code will actually be executed by the Dispatcher thread, so if the person that implements the Listener writes something like void Listener::onSomeEvent() { while(true) ; } The Dispatcher will stuck forever. Is there a "plain old c++" (I mean no boost or libsigc++) way to "decouple" the two classes, so I can be sure that my Dispatcher will work fine whatever the Listeners does in the callbacks? bye and thanks in advance, Andrea

• Is there a good (standalone) PHPDoc parser class or function in PHP?

  - by Kris

  Hi folks, I'm looking for some method of converting a PHP Docblock (as used for generating documentation by tools like Doxygen) into a structure I can inspect in PHP. For example, I want to parse the following lines: /** * Multiply two values * @CHECKME * * @author someone * @created eons ago * * @param integer $x * @param integer $x * * @return integer */ function multiply($x, $y) { return $x * $y; } Into something similar to: array( 'author' = 'someone' ,'created' = 'eons ago' ,'param' = array( 'integer $x' ,'integer $y' ) ,'_flags' = array( '@CHECKME' ) ); I explicitly cannot use PEAR or any such library, it has to be relatively standalone. Any given solution that is better than using a bunch of regexes after stripping away comment outline would be awesome.

• Activate thread synchronically

  - by mayap

  Hi All, I'm using .Net 4.0 parallel library. The tasks I execute, ask to run some other task, sometimes synchronically and somethimes asynchronically, dependending on some conditions which are not known in advanced. For async call, i simply create new tasks and that's it. I don't know how to handly sync call: how to run it from the same thread, maybe that sync tasks will also ask to execute sync tasks recursively. all this issue is pretty new to me. thanks in advance.

• Do (statically linked) DLLs use a different heap than the main program?

  - by happy_emi

  I'm new to Windows programming and I've just "lost" two hours hunting a bug which everyone seems aware of: you cannot create an object on the heap in a DLL and destroy it in another DLL (or in the main program). I'm almost sure that on Linux/Unix this is NOT the case (if it is, please say it, but I'm pretty sure I did that thousands of times without problems...). At this point I have a couple of questions: 1) Do statically linked DLLs use a different heap than the main program? 2) Is the statically linked DLL mapped in the same process space of the main program? (I'm quite sure the answer here is a big YES otherwise it wouldn't make sense passing pointers from a function in the main program to a function in a DLL). I'm talking about plain/regular DLL, not COM/ATL services EDIT: By "statically linked" I mean that I don't use LoadLibrary to load the DLL but I link with the stub library
