  • Get a JQuery function to execute after and independently of onLoad

    - by lewicki
    Is is possible to execute a JQuery function by injecting it into the page? IT CAN'T be attached to the .ready function. The reason is that the user will be uploading an image via iframe. I need JCrop to execute after I display the uploaded image. echo "<script>$('#pictures_step1_right_bottom1', window.parent.document).html('<img id=\"cropbox\" src=\"../../box/" . 'THM' . $filenameAlt . '.jpg' . "\">');</script>"; echo "<script>jQuery(function(){jQuery('#cropbox').Jcrop();});</script>"; This is executed in the iframe that is processing the image. it then sends it to the main page. This does not work however. EDIT: Ended up running a timer: function checkPic() { if($('#cropbox1').length != 0) { jQuery(function() { jQuery('#cropbox1').Jcrop(); }); } timer(); // Check size again after 1 second } function timer(){ var myTimer = setTimeout('checkPic()', 3000); // Check size every 1 second}

  • CS 50- Pset 1 Mario Program

    - by boametaphysica
    the problem set asks us to create a half pyramid using hashes. Here is a link to an image of how it should look- I get the idea and have written the program until printing the spaces (which I have replaced by "_" just so that I can test the first half of it. However, when I try to run my program, it doesn't go beyond the do-while loop. In other words, it keeps asking me for the height of the pyramid and does not seem to run the for loop at all. I've tried multiple approaches but this problem seems to persist. Any help would be appreciated! Below is my code- # include <cs50.h> # include <stdio.h> int main(void) { int height; do { printf("Enter the height of the pyramid: "); height = GetInt(); } while (height > 0 || height < 24); for (int rows = 1; rows <= height, rows++) { for (int spaces = height - rows; spaces > 0; spaces--) { printf("_"); } } return 0; } Running this program yields the following output- Enter the height of the pyramid: 11 Enter the height of the pyramid: 1231 Enter the height of the pyramid: aawfaf Retry: 12 Enter the height of the pyramid:

  • Academic question: typename

    - by Arman
    Hi, recently I accounted with a "simple problem" of porting code from VC++ to gcc/intel. The code is compiles w/o error on VC++: #include <vector> using std::vector; template <class T> void test_vec( std::vector<T> &vec) { typedef std::vector<T> M; /*==> add here typename*/ M::iterator ib=vec.begin(),ie=vec.end(); }; int main() { vector<double> x(100, 10); test_vec<double>(x); return 0; } then with g++ we have some unclear errors: g++ t.cpp t.cpp: In function 'void test_vec(std::vector<T, std::allocator<_CharT> >&)': t.cpp:13: error: expected `;' before 'ie' t.cpp: In function 'void test_vec(std::vector<T, std::allocator<_CharT> >&) [with T = double]': t.cpp:18: instantiated from here t.cpp:12: error: dependent-name 'std::M::iterator' is parsed as a non-type, but instantiation yields a type t.cpp:12: note: say 'typename std::M::iterator' if a type is meant If we add typename before iterator the code will compile w/o pb. If it is possible to make a compiler which can understand the code written in the more "natural way", then for me is unclear why we should add typename? Which rules of "C++ standards"(if there are some) will be broken if we allow all compilers to use without "typename"? kind regards Arman.

  • VS 2008 does not understand .resource files

    - by Dmitry
    I'm trying to add globalization support to my C# application. According to MSDN, there should be one embedded resource file for neutral culture and satellite DLLs with resource files for other cultures. I've created 2 satellite DLLs without any problems and got my app to automatically load right one using ResourceManager. But I can't embed default neutral culture resource file into my executable. When I remove all satellite DLLs or set culture to some culture I don't have satellite DLL for, I get exception "Could not find any resources appropriate for the specified culture or the neutral culture." when application attempts to create ResourceManager. It looks like VS 2008 does not include my .resource file into main assembly. I've tried different ways to get resource file embedded: compiling it by resgen.exe from text file and adding it to the project; changing its name to add second .resources extension; creating .resx file with same name; etc. And I still don't see the way to get resource file embedded and used by ResourceManager - I'm having same exception. What is the right way to add default neutral culture resource file to application in VS 2008 ?

  • Find max integer size that a floating point type can handle without loss of precision

    - by Checkers
    Double has range more than a 64-bit integer, but its precision is less dues to its representation (since double is 64-bit as well, it can't fit more actual values). So, when representing larger integers, you start to lose precision in the integer part. #include <boost/cstdint.hpp> #include <limits> template<typename T, typename TFloat> void maxint_to_double() { T i = std::numeric_limits<T>::max(); TFloat d = i; std::cout << std::fixed << i << std::endl << d << std::endl; } int main() { maxint_to_double<int, double>(); maxint_to_double<boost::intmax_t, double>(); maxint_to_double<int, float>(); return 0; } This prints: 2147483647 2147483647.000000 9223372036854775807 9223372036854775800.000000 2147483647 2147483648.000000 Note how max int can fit into a double without loss of precision and boost::intmax_t (64-bit in this case) cannot. float can't even hold an int. Now, the question: is there a way in C++ to check if the entire range of a given integer type can fit into a loating point type without loss of precision? Preferably, it would be a compile-time check that can be used in a static assertion, and would not involve enumerating the constants the compiler should know or can compute.

  • problem when trying to empty a stack in c

    - by frx08
    Hi all, (probably it's a stupid thing but) I have a problem with a stack implementation in C language, when I try to empty it, the function to empty the stack does an infinite loop.. the top of the stack is never null. where I commit an error? thanks bye! #include <stdio.h> #include <stdlib.h> typedef struct stack{ size_t a; struct stack *next; } stackPos; typedef stackPos *ptr; void push(ptr *top, size_t a){ ptr temp; temp = malloc(sizeof(stackPos)); temp->a = a; temp->next = *top; *top = temp; } void freeStack(ptr *top){ ptr temp = *top; while(*top!=NULL){ //the program does an infinite loop *top = temp->next; free(temp); } } int main(){ ptr top = NULL; push(&top, 4); push(&top, 8); //down here the problem freeStack(&top); return 0; }

  • Java 7u4 webstart security exception: Class does not match trust level

    - by Glstunna
    We began to notice that with Java 7 (particularly with update 4), that all our users began to see this with our Webstart app: [14:42:58,422] AWT-EventQueue-0(DEBUG) java.lang.SecurityException: class "CLASSNAME" does not match trust level of other classes in the same package [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.deploy.security.CPCallbackHandler$ChildElement.checkResource(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.deploy.security.DeployURLClassPath$JarLoader.checkResource(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.deploy.security.DeployURLClassPath$JarLoader.getResource(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.deploy.security.DeployURLClassPath.getResource(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.net.URLClassLoader$1.run(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.net.URLClassLoader$1.run(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.security.AccessController.doPrivileged(Native Method) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.net.URLClassLoader.findClass(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at com.sun.jnlp.JNLPClassLoader.findClass(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.lang.ClassLoader.loadClass(Unknown Source) [14:42:58,422] AWT-EventQueue-0(DEBUG) at java.lang.ClassLoader.loadClass(Unknown Source)...More Where CLASSNAME = pretty much every class at random points from several jars in the app execution, breaking several behavior. If our users were to use Java 6, they have no problems! Just 7 (update 4). We sign ALL our jars, both the main application jar and it's library jars. i.e Users launching our webstart app see the blue shield instead of yellow or red. This is obviously an issue as users are more frequently now upgrading to Java 7. I have tried to force our app to use Java 6 on the user machine either by using a previous installation(works), or installing a new one....with the j2se version="1.6" tag around resources but this causes it's own problems that would probably be best to make into it's own thread (the auto-jre-installation part). Did Oracle break Webstart security with Java 7u4? How do I solve this securityexception issue?

  • Remove Activity as Default Launcher

    - by sixeightzero
    I set my activity as a default launcher to intercept home button clicks like so: <activity android:name=".ExampleActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> <category android:name="android.intent.category.HOME" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> When my activity, ExampleActivity is launched, if i click the home key, I get prompted to choose. If I select make this my default and chose my activity, I am stuck In my activity as desired. The problem is, when I leave the activity, I try to remove my activity from the default launcher, but am unsuccessful. I have tried: ComponentName componentName = new ComponentName( "com.example.exampleactivity", "com.example.exampleactivity.class"); pm.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DEFAULT, PackageManager.DONT_KILL_APP); And: PackageManager pm = getActivity().getPackageManager(); ComponentName name = new ComponentName(this, "com.example.exampleactivity.class"); pm.setComponentEnabledSetting(name, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 0); But my designation for the home is never removed. Does anyone have a working way to fix the above? I only wan't the home button to be default for a specific activity, not my entire application. When I leave the activity, it should be removed and restored to default.

  • Launch User Control in a tab control dynamically

    - by Redburn
    I have a custom built menu system in which I would like to load user controls from another project into a tab control on my main project (menu control) User control Project : foobar Menu system Project : Menu The function to load them into the tab control: private void LaunchWPFApplication(string header, string pPath) { // Header - What loads in the tabs header portion. // pPath - Page where to send the user //Create a new browser tab object BrowserTab bt = tabMain.SelectedItem as BrowserTab; bt = new BrowserTab(); bt.txtHeader.Text = header; bt.myParent = BrowserTabs; //Load in the path try { Type formType = Type.GetType(pPath, true); bt.Content = (UserControl)Activator.CreateInstance(formType); } catch { MessageBox.Show("The specified user control : " + pPath + " cannot be found"); } //Add the browser tab and then focus BrowserTabs.Add(bt); bt.IsSelected = true; } And what I send to the function as an example: LaunchWPFApplication("Calculater", "foobar.AppCalculater"); But every time run, the application complains that the formType is null. I am confused on how to load the user control and curious if I'm sending the correct parameters.

  • Custom .NET DSL

    - by Dmitriy Nagirnyak
    Hi, I am thinking about implementing a templating engine using only the plain C#/.NET 4 syntax with the benefit of static typing. Then on top of that templating language we could create Domain Specific Languages (let's say HTML4, XHTML, HTML5, RSS, Atom, Multipart Emails and so on). One of the best DSLs in .NET 4 (if not only one) is SharpDOM. It implements HTML-specific DSL. Looking at SharpDOM, I am really impressed of what you can do using .NET (4). So I believe there are some not-so-well-known ways for implementing custom DSLs in .NET 4. Possibly not as well as in Ruby, but still. So my the question would be: what are the C# (4) specific syntax features that can be used for implementing custom DSLs? Examples I can think of right now: // HTML - doesn't look tooo readable :) div(clas: "head", ul(clas: "menu", id: "main-menu", () => { foreach(var item in allItems) { li(item.Name) } }) // See how much noise it has with all the closing brackets? ) // Plain text (Email or something) - probably too simple Line("Dear {0}", user.Name); Line("You have been kicked off from this site"); For me it is really hard to come up with the syntax with least amount of noise. Please NOTE that I am not talking about another language (Boo, IronRuby etc), neither I am not talking about different templating engines (NHaml, Spark, StringTemplate etc). Thanks, Dmitriy.

  • How can I control the action of onbeforeunload in IE?

    - by SpawnCxy
    Hi all I've got a problem about onbeforeunload recently that I need to pop up a voting page if the user try closes their IE browser.And I did it by using <body onbeforeunload="makevote()"> And the main structure of makevote() in javascript as follows: function makevote() { comet.distruct(); if(csid != null && isvote == null) { window.event.returnValue = false window.event.returnValue='press “cancel” to vote please!' showComDiv(popvote,"popiframe",400,120,'your vote here','dovote()'); } } For last three months this voting function performed so ugly that I got only less than 8,000 votes from more than 4,50,000 vistors.I think the problem is, when the users try to close their browsers,the onbeforeunload property pops up a comfirm box which covered my voting box while most users click the OK button,which means close comfirming is done,as a habit.So my question is how can I control the comfirming box made by onbeforeunload myself? So far I can only define the message it shows.For example if I click the "OK" ,I'll go to the voting box instead of closing my IE.And if there's any other better way to do this?Help would be greatly appreciated! Regards

  • Just introducing myself to TMPing, and came across a quirk

    - by Justen
    I was just trying to learn the syntax of the beginner things, and how it worked when I was making this short bit of code. The code below works in adding numbers 1 to 499, but if I add 1 to 500, the compiler bugs out giving me: fatal error C1001: An internal error has occurred in the compiler. And I was just wondering why that is. Is there some limit to how much code the compiler can generate or something and it just happened to be a nice round number of 500 for me? #include <iostream> using namespace std; template < int b > struct loop { enum { sum = loop< b - 1 >::sum + b }; }; template <> struct loop< 0 > { enum { sum = 0 }; }; int main() { cout << "Adding the numbers from 1 to 499 = " << loop< 499 >::sum << endl; return 0; }

  • Best way to pass image to server?

    - by Chris
    I have an SL3 application that needs to be able to pass an image to the server, and then the server will generate a PDF file with the image in it, and display it to the user. What I already have in place are the following: (1) Code to convert image to byte array (2) Code to generate PDF file with image The main problem that I am running into is the following: In order to bypass the pop-up blocker, which is a requirement for my application, I am using the following code: var button = new NavigationButton(); button.NavigateUri = new Uri("http://localhost:3616/PrintReport.aspx?ReportIndex=11&ActionType=Get&ReportIdentifier=" + reportIdentifier.ToString() + ""); button.TargetName = "_blank"; button.PerformClick(); Initially, I would pass the image to a WCF web service (as a byte array), and then "navigate" to the ASP.NET page that would display the report. However, if I do this, then I can not use my custom HyperlinkButton class, and, certain browsers, including Safari, will block a new window from opening up. Therefore, it appears that the only option is to use the HyperlinkButton class. What I need to be able to do is to somehow pass the image, as a byte array or some other data type, to the server, such that it can temporarily store the image, even if it is in a server variable, and then immediately retrieve it when I navigate to the PrintReport.aspx page. If I upload the image to an ASP.NET form and then use the HyperlinkButton class to navigate to the PrintReport page, it doesn't work, as the app navigates to the PrintReport page before the system has finished uploading the image. I can't pass it to a web service, as that would require that I navigate to the PrintReport.aspx page in the callback code of the web method that I would be passing the image to, and the HyperlinkButton will not allow that, based on security rules. Any help or ideas would be appreciated. Thanks. Chris

  • How to access generic property without knowing the closed generic type

    - by Martin Booka Weser
    I have a generic Type as follows public class TestGeneric<T> { public T Data { get; set; } public TestGeneric(T data) { this.Data = data; } } If i have now an object (which is coming from some external source) from which i know that it's type is of some closed TestGeneric<, but i don't know the TypeParameter T. Now I need to access the Data of my object. Problem is that i can't cast the object, since i don't know exactly to which closed TestGeneric. I use // thx to http://stackoverflow.com/questions/457676/c-reflection-check-if-a-class-is-derived-from-a-generic-class private static bool IsSubclassOfRawGeneric(Type rawGeneric, Type subclass) { while (subclass != typeof(object)) { var cur = subclass.IsGenericType ? subclass.GetGenericTypeDefinition() : subclass; if (rawGeneric == cur) { return true; } subclass = subclass.BaseType; } return false; } to make sure, my object is of the generic type. The code in question is as follows: public static void Main() { object myObject = new TestGeneric<string>("test"); // or from another source if (IsSubclassOfRawGeneric(typeof(TestGeneric<>), myObject.GetType())) { // the following gives an InvalidCastException // var data = ((TestGeneric<object>)myObject).Data; // if i try to access the property with reflection // i get an InvalidOperationException var dataProperty = typeof(TestGeneric<>).GetProperty("Data"); object data = dataProperty.GetValue(myObject, new object[] { }); } } I need the Data regardless of its type (well, if i could ask for its type using GetType() would be fine, but not necessary) since i just want to dump it in xml using ToString(). Any suggestions? Thanx.

  • Matlab-Bisection-Newton-Secant , finding roots?

    - by i z
    Hello and thanks in advance for your possible help ! Here's my problem: I have 2 functions f1(x)=14.*x*exp(x-2)-12.*exp(x-2)-7.*x.^3+20.*x.^2-26.*x+12 f2(x)=54.*x.^6+45.*x.^5-102.*x.^4-69.*x.^3+35.*x.^2+16.*x-4 Make the graph for those 2, the first one in [0,3] and the 2nd one in [-2,2]. Find the 3 roots with accuracy of 6 decimal digits using a) bisection ,b) newton,c)secant.For each root find the number of iterations that have been made. For Newton-Raphson, find which roots have quadratic congruence and which don't. What is the main common thing that roots with no quadratic congruence (Newton's method)? Why ? Excuse me if i ask silly things, but i'm asked to do this with no Matlab courses and I'm trying to learn it myself. There are many issues i have with this exercise . Questions : 1.I only see 2 roots in the graph for the f1 function and 4-5 (?) roots for the function f2 and not 3 roots as the exercise says. Here's the 2 graphs : http://postimage.org/image/cltihi9kh/ http://postimage.org/image/gsn4sg97f/ Am i wrong ? Do both have only 3 roots in [0,3] and [-2,2] ? Concerning the Newton's method , how am i supposed to check out which roots have quadratic congruence and which not??? Accuracy means tolerance e=10^(-6), right ?

  • Converting a bash script to python (small script)

    - by Mestika
    Hi, I’ve a bash script I’ve been using for a Linux environment but now I have to use it on a Windows platform and want to convert the bash script to a python script which I can run. The bash script is rather simple (I think) and I’ve tried to convert it by google by way around but can’t convert it successfully. The bash script looks like this: runs=5 queries=50 outfile=outputfile.txt date >> $outfile echo -e "\n---------------------------------" echo -e "\n----------- Normal --------------" echo -e "\n---------------------------------" echo -e "\n----------- Normal --------------" >> $outfile for ((r = 1; r < ($runs + 1); r++)) do echo -e "Run $r of $runs\n" db2 FLUSH PACKAGE CACHE DYNAMIC python reads.py -r1 -pquery1.sql -q$queries -shotelspec -k6 -a5 >> $outfile done The main command, the python read.py … etc. is another python file I’ve been given and have the arguments as you see. I know it is a lot to ask for, but it would really help me out if someone could convert this to a python script I can use or at least give me some hints and directions. Sincerely Mestika

  • Disabling redraw in WinForms app

    - by Ryan
    I'm working on a C#.Net application which has a somewhat annoying bug in it. The main window has a number of tabs, each of which has a grid on it. When switching from one tab to another, or selecting a different row in a grid, it does some background processing, and during this the menu flickers as it's redrawn (File, Help, etc menu items as well as window icon and title). I tried disabling the redraw on the window while switching tabs/rows (WM_SETREDRAW message) at first. In one case, it works perfectly. In the other, it solves the immediate bug (title/menu flicker), but between disabling the redraw and enabling it again, the window is "transparent" to mouse clicks - there's a small window (<1 sec) in which I can click and it will, say, highlight an icon on my desktop, as if the app wasn't there at all. If I have something else running in the background (Firefox, say) it will actually get focus when clicked (and draw part of the browser, say the address bar.) Here's code I added. m = new Message(); m.HWnd = System.Windows.Forms.Application.OpenForms[0].Handle; //top level m.WParam = (IntPtr)0; //disable redraw m.LParam = (IntPtr)0; //unused m.Msg = 11; //wm_setredraw WndProc(ref m); <snip - Application ignores clicks while in this section (in one case) m = new Message(); m.HWnd = System.Windows.Forms.Application.OpenForms[0].Handle; //top level m.WParam = (IntPtr)1; //enable m.LParam = (IntPtr)0; //unused m.Msg = 11; //wm_setredraw WndProc(ref m); System.Windows.Forms.Application.OpenForms[0].Refresh(); Does anyone know if a) there's a way to fix the transparent-application problem here, or b) if I'm doing it wrong in the first place and this should be fixed some other way?

  • Direct invocation vs indirect invocation in C

    - by Mohit Deshpande
    I am new to C and I was reading about how pointers "point" to the address of another variable. So I have tried indirect invocation and direct invocation and received the same results (as any C/C++ developer could have predicted). This is what I did: int cost; int *cost_ptr; int main() { cost_ptr = &cost; //assign pointer to cost cost = 100; //intialize cost with a value printf("\nDirect Access: %d", cost); cost = 0; //reset the value *cost_ptr = 100; printf("\nIndirect Access: %d", *cost_ptr); //some code here return 0; //1 } So I am wondering if indirect invocation with pointers has any advantages over direct invocation or vice-versa. Some advantages/disadvantages could include speed, amount of memory consumed performing the operation (most likely the same but I just wanted to put that out there), safeness (like dangling pointers) , good programming practice, etc. 1Funny thing, I am using the GNU C Compiler (gcc) and it still compiles without the return statement and everything is as expected. Maybe because the C++ compiler will automatically insert the return statement if you forget.

  • MongoMapper won't let me create an object

    - by Jade
    I'm just learning MongoDB and MongoMapper. This is on Rails 3. I created a blog in app/models/blog.rb: class Blog include MongoMapper::Document key :title, String, :required => true key :body, Text timestamps! end I go into the Rails console: rails c Loading development environment (Rails 3.0.0.beta) ruby-1.9.1-p378 > **b = Blog.new** NoMethodError: undefined method `from_mongo' for Text:Module from /Users/jade/.rvm/gems/ruby-1.9.1-p378/gems/mongo_mapper-0.7.2/lib/mongo_mapper/plugins/keys.rb:323:in `get' from /Users/jade/.rvm/gems/ruby-1.9.1-p378/gems/mongo_mapper-0.7.2/lib/mongo_mapper/plugins/keys.rb:269:in `read_key' from /Users/jade/.rvm/gems/ruby-1.9.1-p378/gems/mongo_mapper-0.7.2/lib/mongo_mapper/plugins/keys.rb:224:in `[]' from /Users/jade/.rvm/gems/ruby-1.9.1-p378/gems/mongo_mapper-0.7.2/lib/mongo_mapper/plugins/inspect.rb:7:in `block in inspect' from /Users/jade/.rvm/gems/ruby-1.9.1-p378/gems/mongo_mapper-0.7.2/lib/mongo_mapper/plugins/inspect.rb:6:in `collect' from /Users/jade/.rvm/gems/ruby-1.9.1-p378/gems/mongo_mapper-0.7.2/lib/mongo_mapper/plugins/inspect.rb:6:in `inspect' from /Users/jade/.rvm/gems/ruby-1.9.1-p378/gems/railties-3.0.0.beta/lib/rails/commands/console.rb:47:in `start' from /Users/jade/.rvm/gems/ruby-1.9.1-p378/gems/railties-3.0.0.beta/lib/rails/commands/console.rb:8:in `start' from /Users/jade/.rvm/gems/ruby-1.9.1-p378/gems/railties-3.0.0.beta/lib/rails/commands.rb:34:in `<top (required)>' from /Users/jade/code/farmerjade/script/rails:10:in `require' from /Users/jade/code/farmerjade/script/rails:10:in `<main>' Am I overlooking something really dumb, or is this something in my setup?

  • Using git pull to track a remote branch without merging

    - by J Barlow
    I am using git to track content which is changed by some people and shared "read-only" with others. The "readers" may from time to time need to make a change, but mostly they will not. I want to allow for the git "writers" to rebase pushed branches** if need be, and ensure that the "readers" never accidentally get a merge. That's normally easy enough. git pull origin +master There's one case that seems to cause problems. If a reader makes a local change, the command above will merge. I want pull to be fully automatic if the reader has not made local changes, while if they have made local changes, it should stop and ask for input. I want to track any upstream changes while being careful about merging downstream changes. In a way, I don't really want to pull. I want to track the master branch exactly. ** (I know this is not a best practice, but it seems necessary in our case: we have one main branch that contains most of the work and some topic branches for specific customers with minor changes that need to be isolated. It seems easiest to frequently rebase to keep the topics up to date.)

  • How to get interpolated message in NHibernate.Validator

    - by SztupY
    Hi! I'm trying to integrate NHibernate.Validator with ASP.NET MVC client side validations, and the only problem I found is that I simply can't convert the non-interpolated message to a human-readable one. I thought this would be an easy task, but turned out to be the hardest part of the client-side validation. The main problem is that because it's not server-side, I actually only need the validation attributes that are being used, and I don't actually have an instance or anything else at hand. Here are some excerpts from what I've been already trying: // Get the the default Message Interpolator from the Engine IMessageInterpolator interp = _engine.Interpolator; if (interp == null) { // It is null?? Oh, try to create a new one interp = new NHibernate.Validator.Interpolator.DefaultMessageInterpolator(); } // We need an instance of the object that needs to be validated, se we have to create one object instance = Activator.CreateInstance(Metadata.ContainerType); // we enumerate all attributes of the property. For example we have found a PatternAttribute var a = attr as PatternAttribute; // it seems that the default message interpolator doesn't work, unless initialized if (interp is NHibernate.Validator.Interpolator.DefaultMessageInterpolator) { (interp as NHibernate.Validator.Interpolator.DefaultMessageInterpolator).Initialize(a); } // but even after it is initialized the following will throw a NullReferenceException, although all of the parameters are specified, and they are not null (except for the properties of the instance, which are all null, but this can't be changed) var message = interp.Interpolate(new InterpolationInfo(Metadata.ContainerType, instance, PropertyName, a, interp, a.Message)); I know that the above is a fairly complex code for a seemingly simple question, but I'm still stuck without solution. Is there any way to get the interpolated string out of NHValidator?

  • Is there anything like Unity for simple things that don't require an interface?

    - by Dave
    Perhaps I'm misapplying Unity, but here goes. I have a couple of applications, both of which load the same plugin assemblies. All assemblies require a library, and I want them to be able to access this library via Unity. However, in order to use Unity, or any other IoC framework, I'd have to write an interface for this library. I will probably do this, but since an interface isn't really needed for anything other than to support Unity, I am afraid that this means that I am 1) missing the point, or 2) misapplying the framework. If I avoid something that offers me DI, then I'd have to make the library class a singleton, and then pass it to all of the plugin constructors, or via a public property, and I don't want to do this. That said, and without actually implementing anything with Unity yet, I'm not getting one other detail -- although Unity will let me request the library via Resolve<, my plugins will still need to have a reference to the Unity instance that is created in the main applications. So is this a case where your only option is to pass the Unity reference to all of the plugins, but then it's convenient from that point on, merely because you can use Unity to get at all of the other dependencies?
