  • wpf & validation application block > message localization > messageTemplateResource Name&Type

    - by Shaboboo
    I'm trying to write validation rules for my data objects in a WPF application. I'm writing them in the configuration file, and so far they are working fine. I'm stumped on how to localize the messages using messageTemplateResourceName and messageTemplateResourceType. What I know is that the strings can be writen in a resource file, given a name and referenced by that name. I get the idea, but i haven't been able to make this work. <ruleset name="Rule Set"> <properties> <property name="StringValue"> <validator lowerBound="0" lowerBoundType="Ignore" upperBound="25" upperBoundType="Inclusive" negated="false" messageTemplate="" messageTemplateResourceName="msg1" messageTemplateResourceType="Resources" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.EnterpriseLibrary.Validation" name="String Length Validator" /> </property> </properties> </ruleset> Where is the resource file and what value do I pass to messageTemplateResourceType? I have tried writing the messages in the shell project's resource file but no sucess trying to retrieve the value. I only get the default built-in message. I've tried messageTemplateResourceType="typeof(Resources)" messageTemplateResourceType="Resources" messageTemplateResourceType="Resources.resx" messageTemplateResourceType="typeof(Shell)" messageTemplateResourceType="Shell" messageTemplateResourceType="Shell, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" I've also tried adding a new resource file in the shell project, and adding a resource file to the data object's library. I'm all out of ideas Does anyone have any suggestions? I'm not even married to the idea of resource files, so if there are other ways to localize these messages I'd love to know! thanks

  • Building a custom CMS, how to handle page settings?

    - by davidosomething
    Not a coldfusion specific question so answer however you can. I've inherited a ColdFusion project where at the top of every page various page-setting specific variables are set, such as: <cfset request.page.title = "Example Page"> <cfset request.page.machineTitle = "example_page"> <cfset request.page.isJQueryEnabled = 1> <cfset request.page.showNavigation = 1> <cfset request.page.SWFObjectVersion = 2.2> I'm thinking about creating a database table with just integer page_id varchar key varchar value I'd reduce the variables at the top of every page to just the page id, and then call the DB for the correct settings. Is this a good idea? I hate reinventing the wheel, but this is a really big project that would require many months for a full content migration to a CMS. What are the current practices for storing page settings? (e.g., what does WordPress do? Drupal? etc.)

  • Internationalizing a Python 2.6 application via Babel

    - by Malcolm
    We're evaluating Babel 0.9.5 [1] under Windows for use with Python 2.6 and have the following questions that we we've been unable to answer through reading the documentation or googling. 1) I would like to use an _ like abbreviation for ungettext. Is there a concencus on whether one should use n_ or N_ for this? n_ does not appear to work. Babel does not extract text. N_ appears to partially work. Babel extracts text like it does for gettext, but does not format for ngettext (missing plural argument and msgstr[ n ].) 2) Is there a way to set the initial msgstr fields like the following when creating a POT file? I suspect there may be a way to do this via Babel cfg files, but I've been unable to find documentation on the Babel cfg file format. "Project-Id-Version: PROJECT VERSION\n" "Language-Team: en_US \n" 3) Is there a way to preserve 'obsolete' msgid/msgstr's in our PO files? When I use the Babel update command, newly created obsolete strings are marked with #~ prefixes, but existing obsolete message strings get deleted. Thanks, Malcolm [1] http://babel.edgewall.org/

  • Maven: properties not being substituted

    - by jobrahms
    I'm using a maven plugin for install4j in my project, located here. That plugin lets you pass variables to install4j using the <compilerVariables> section. Here's the relevant section of my pom: <plugin> <groupId>com.google.code.maven-install4j</groupId> <artifactId>maven-install4j-plugin</artifactId> <version>0.1.1</version> <configuration> <executable>${devenv.install4jc}</executable> <configFile>${basedir}/newinstaller/ehd.install4j</configFile> <releaseId>${project.version}</releaseId> <attach>false</attach> <skipOnMissingExecutable>false</skipOnMissingExecutable> <compilerVariables> <property> <name>m2_home</name> <value>${settings.localRepository}</value> </property> </compilerVariables> </configuration> </plugin> The problem is that ${settings.localRepository} is not being substituted with the actual directory when I run the plugin. Here's the command line script that install4j is generating: [INFO] Running the following command for install4j compile: /bin/sh -c /home/zach/install4j/bin/install4jc --release=9.1-SNAPSHOT --destination="/home/zach/projects/java/ehdtrunk/target/install4j" -D m2_home=${settings.localRepository} /home/zach/projects/java/ehdtrunk/newinstaller/ehd.install4j Is this the fault of the plugin? If so, what needs to change to allow the substitution to happen?

  • How to properly downcast in C# with a SWIG generated interface?

    - by JG
    I've got a very large and mature C++ code base that I'm trying to use SWIG on to generate a C# interface for. I cannot change the actual C++ code itself but we can use whatever SWIG offers in the way of extending/updating it. I'm facing an issue where a function C++ is written as such: A* SomeClass::next(A*) The caller might do something like: A* acurr = 0; while( (acurr = sc->next(acurr)) != 0 ){ if( acurr isoftype B ){ B* b = (B*)a; ...do some stuff with b.. } elseif( acurr isoftype C ) ... } Essentially, iterating through a container elements that depending on their true type, do something different. The SWIG generated C# layer for the "next" function unfortunately does the following: return new A(); So the calling code in C# land cannot determine if the returned object is actually a derived class or not, it actually appears to always be the base class (which does make sense). I've come across several solutions: Use the %extend SWIG keyword to add a method on an object and ultimately call dynamic_cast. The downside to this approach, as I see it, is that this requires you to know the inheritance hierarchy. In my case it is rather huge and I see this is as a maintenance issue. Use the %factory keyword to supply the method and the derived types and have SWIG automatically generate the dynamic_cast code. This appears to be a better solution that the first, however upon a deeper look it still requires you to hunt down all the methods and all the possible derived types it could return. Again, a huge maintenance issue. I wish I had a doc link for this but I can't find one. I found out about this functionality by looking through the example code that comes with SWIG. Create a C# method to create an instance of the derived object and transfer the cPtr to the new instance. While I consider this clumsy, it does work. See an example below. public static object castTo(object fromObj, Type toType) { object retval = null; BaseClass fromObj2 = fromObj as BaseClass; HandleRef hr = BaseClass.getCPtr(fromObj2); IntPtr cPtr = hr.Handle; object toObj = Activator.CreateInstance(toType, cPtr, false); // make sure it actually is what we think it is if (fromObj.GetType().IsInstanceOfType(toObj)) { return toObj; } return retval; } Are these really the options? And if I'm not willing to dig through all the existing functions and class derivations, then I'm left with #3? Any help would be appreciated.

  • Understanding MongoDB (and NoSQL in general) and how to make the best use of it

    - by Earlz
    Hello, I am beginning to think that my next project I am wanting to do would work better with a NoSQL solution. The project would either involve a ton of 2-column tables or a ton of dynamic queries with dynamically generated columns in a traditional SQL database. So I feel a NoSQL database would be much cleaner. I'm looking at MongoDB and it looks pretty promising. Anyway, I'm attempting to make sense of it all. Also, I will be using MongoMapper in Ruby. Anyway though, I'm confused as to how to layout things in such a freeform database. I've read http://stackoverflow.com/questions/2170152/nosql-best-practices and the answer there says that normalization is usually bad in a NoSQL DB. So how would be the best way of laying out say a simple blog with users, posts, and comments? My natural thought was to have three collections for each and then link them by a unique ID. But this apparently is wrong? So, what are some of the ways to lay out such a thing? My concern with the answer given in the other question is, what if the author's name changed? You'd have to go through updating a ton of posts and comments. But is this an okay thing to do with NoSQL?

  • Object addSubview only works in viewDidLoad

    - by DecodingSand
    Hi, I'm new to iPhone dev and need some help with adding subViews. I have a reusable object that I made that is stored in a separate .h .m and xib file. I would like to use this object in my main project's view controller. I have included the header and the assignment of the object generates no errors. I am able to load the object into my main project but can only do things with it inside my viewDidLoad method. I intend to have a few of these objects on my screen and am looking fora solution that is more robust then just hard wiring up multiple copies of the shape object. As soon as I try to access the object outside of the viewDidLoad it produces a variable unknown error - first use in this function. Here is my viewDidLoad method: shapeViewController *shapeView = [[shapeViewController alloc] initWithNibName:@"shapeViewController" bundle:nil]; [self.view addSubview: shapeView.view]; // This is the problem line // This code works changes the display on the shape object [shapeView updateDisplay:@"123456"]; ---- but the same code outside of the viewDidLoad generates the error. So to sum up, everything works except when I try to access the shapeView object in the rest of the methods. Thanks in advance

  • Best language for scripting large scale file management

    - by Dan
    The National Park Service's Natural Sounds Program collects multiple terabytes of data each year measuring soundscapes. In your opinion, what is best available scripting language to manage massive amounts of files and file types? We would like to easily design and run efficient user-friendly scripts to search for and retrieve/create copies of files that may be located in different directories according a single static hierarchy. The OS will most likely be windows. Thanks!

  • Python vs. Java performance (runtime speed)

    - by Bijan
    Ignoring all the characteristics of each languages and focusing SOLELY on speed, which language is better performance-wise? You'd think this would be a rather simple question to answer, but I haven't found a decent one. I'm aware that some types of operations may be faster with python, and vice-versa, but I cannot find any detailed information on this. Can anyone shed some light on the performance differences?

  • Classloader issue (GWT)

    - by Banang
    I'm currently working on a gwt app, where the server uses a few third party libs. recently I discovered that one of these libs isn't being properly loaded when running my app in deployed mode, and I just can't seem to figure out what out is I'm doing wrong. In my build script I have the following classpath declaration: <path id="project.class.path"> <pathelement location="${war.dir}/WEB-INF/classes"/> <fileset dir="${war.dir}/WEB-INF/lib" includes="**/*.jar"/> </path> and in a later target I copy the jar I need to the right location: <copy todir="${war.dir}/WEB-INF/lib" file="someJar.jar" /> The project builds as it should, without any errors. The jars are copied to where the should be, and are included in the resulting war file. In development mode everything is working as it should, everything gets loaded properly and I hear no complaints. However, in the deployed version I get this thrown at me: java.lang.NoClassDefFoundError: org/apache/commons/lang/exception/NestableRuntimeException java.lang.ClassLoader.defineClass1(Native Method) java.lang.ClassLoader.defineClass(ClassLoader.java:621) java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:2331) org.apache.catalina.loader.WebappClassLoader.findClass(WebappClassLoader.java:976) org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1451) org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1329) java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) my.package.server.util.SomeUtils.doSomethingFantastic(SomeUtils.java:84) Line 84 in SomeUtils is trying to instantiate a class from someJar.jar. I know very little about how the class loader for gwt works, and I sure could use a hand. Anyone got any ideas on how to solve this?

  • Should the PHP community start using more descriptive Exceptions?

    - by fireeyedboy
    I work with Zend Framework a lot and I just took a peek at Kohana, and it strikes me as odd that this is a typical scenario in these frameworks: throw Some_Componenents_Exception( 'invalid argument' ); Where I believe this wouldn't be mouch more useful: throw Some_Components_InvalidArgumentException( 'whatever discription' ); Because it is easier to catch. I suspect, but immediately admit it's prejudiced, that the former practice is common in the PHP community. Should we, the PHP community, start using these descriptive types of expections more?

  • Weird bug with C++ lambda expressions in VS2010

    - by Andrei Tita
    In a couple of my projects, the following code: class SmallClass { public: int x1, y1; void TestFunc() { auto BadLambda = [&]() { int g = x1 + 1; //ok int h = y1 + 1; //c2296 int l = static_cast<int>(y1); //c2440 }; int y1_copy = y1; //it works if you create a local copy auto GoodLambda = [&]() { int h = y1_copy + 1; //ok int l = this->y1 + 1; //ok }; } }; generates error C2296: '+' : illegal, left operand has type 'double (__cdecl *)(double)' or alternatively error C2440: 'static_cast' : cannot convert from 'double (__cdecl *)(double)' to 'int' You get the picture. It also happens if catching by value. The error seems to be tied to the member name "y1". It happened in different classes, different projects and with (seemingly) any type for y1; for example, this code: [...] MyClass y1; void TestFunc() { auto BadLambda = [&]()->void { int l = static_cast<int>(y1); //c2440 }; } generates both these errors: error C2440: 'static_cast' : cannot convert from 'MyClass' to 'int' No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called error C2440: 'static_cast' : cannot convert from 'double (__cdecl *)(double)' to 'int' There is no context in which this conversion is possible It didn't, however, happen in a completely new project. I thought maybe it was related to Lua (the projects where I managed to reproduce this bug both used Lua), but I did not manage to reproduce it in a new project linking Lua. It doesn't seem to be a known bug, and I'm at a loss. Any ideas as to why this happens? (I don't need a workaround; there are a few in the code already). Using Visual Studio 2010 Express version 10.0.40219.1 Sp1Rel.

  • Use reflection to get a list of static classes

    - by Christian
    Hi, many questions are close, but none answers my problem... How do I use reflection in C# 3.5 to get all classes which are static from an assembly. I already get all Types defined, but there is no IsStatic property. Counting 0 constructors is really slow and did not work either. Any tips or a line of code? :-) Chris

  • Jquery Cycle Lite plugin unable to see images that have been loaded by an AJAX call

    - by William Macdonald
    Hi, I am having problems using the jquery cycle lite plugin on some images that are added via AJAX. Here is the jquery code: $(function() { resizeWindow(); $(window).bind("resize", resizeWindow); $("#assignment-nav").accordion({ header: "h3", autoHeight: false }); $(".project").click(function() { // get the HTML and load into div $('.image-holder').empty(); var justTheNumber = $(this).attr('id').replace('project-',''); $.get("get_project_images.php", {project_id:justTheNumber}, function(data){ $('.image-holder').append(data); } ); $(".image-holder").cycle({ // Cycle plugin prev: '#prev', next: '#next', timeout: 0, speed: 250 }) }); }); My code works fine in that the IMG tags are loaded and the first image of the slide show is displayed. However the prev/next buttons don't work. When I load the images via static HTML the slideshow prev/next links works fine. (I just copied and pasted the generated HTML.) I understand I need to use something like .bind or .live to make the Cycle plugin 'see' the new images. I have tried everything I can think of but I can't make it work. What am I doing wrong ?

  • Is there a "good enough" solution for the halting problem?

    - by EpsilonVector
    It is known that the halting problem cannot have a definite solution, one that a) returns true <== the program does indeed halt, and b) handles any input, but I was wondering if there are good enough solutions to the problem, ones that can maybe handle certain types of program flows perfectly, or is able to identify it when it cannot correctly solve the problem, and so on.... If so, how good are they, and what ideas/limitations do they rely on?

  • Managing NSStoreType changes between debug and release builds

    - by Eimantas
    NSXMLTypeStore is used when starting Core Data backed application by default because it's good for debugging purposes. But practice dictates that developer should use either NSBinaryStoreType, NSInMemoryStoreType or NSSQLiteStoreType store types in release builds. How do you manage changes between debug and release builds? I believe that changing store type from NSXMLTypeStore to, say, NSBinaryStoreType in code on each release is kinda cumbersome.
