  • Intercept Properties With Castle Windsor IInterceptor

    - by jeffn825
    Does anyone have a suggestion on a better way to intercept a properties with Castle DynamicProxy? Specifcally, I need the PropertyInfo that I'm intercepting, but it's not directly on the IInvocation, so what I do is: public static PropertyInfo GetProperty(this MethodInfo method) { bool takesArg = method.GetParameters().Length == 1; bool hasReturn = method.ReturnType != typeof(void); if (takesArg == hasReturn) return null; if (takesArg) { return method.DeclaringType.GetProperties() .Where(prop => prop.GetSetMethod() == method).FirstOrDefault(); } else { return method.DeclaringType.GetProperties() .Where(prop => prop.GetGetMethod() == method).FirstOrDefault(); } } Then in my IInterceptor: #region IInterceptor Members public void Intercept(IInvocation invocation) { bool doSomething = invocation.Method.GetProperty().GetCustomAttributes(true).OfType<SomeAttribute>().Count() > 0; } #endregion Thanks.

  • what is the right way to exit Windoes Service OnStart if configuration is wrong and nothing to do in

    - by matti
    Is something like this ok? protected override void OnStart(string[] args) { if (SomeApp.Initialize()) { SomeApp.StartMonitorAndWork(); base.OnStart(args); } } protected override void OnStop() { SomeApp.TearDown(); base.OnStop(); } Here Initialize reads a config file and if it's wrong there's nothing to do so service should STOP! If config is ok StartMonitorAndWork starts: Timer(new TimerCallback(DoWork), null, startTime, loopTime); and DoWork polls database periodically. The question is: "Is exiting OnStart without doing nothing enough if Initialize returns false? OR should there be something like this: private void ExitService() { this.OnStop(); System.Environment.Exit(1); } protected override void OnStart(string[] args) { if (ObjectFolderApp.Initialize()) { SomeApp.StartMonitorAndWork(); base.OnStart(args); } else { ExitService(); } } Thanks & BR - Matti

  • eclise java internal webbrowser progress listener?

    - by deepthinker121
    Hi All, I need to open an internal web browser from a custom eclipse wizard I have created - and so I am using IWebBrowser webBrowser = browser.createBrowser (IWorkbenchBrowserSupport.LOCATION_BAR | IWorkbenchBrowserSupport.AS_EDITOR | IWorkbenchBrowserSupport.NAVIGATION_BAR | IWorkbenchBrowserSupport.STATUS, null,"TestBrowser", "TestBrowser"); URL url = new URL("http://localhost:8080/app"); webBrowser.openURL(url); Now the problem is - the openURL needs time to complete as it tries to load a page for a webapp and as I am not able to get the progress of the 'load page' operation of the URL - my wizard progressmonitor completes before the URL can be completely loaded . Is there any way to get the status of the page load operation - (to check if its complete or it failed) or add a listener to indicate completion of page load? It is okay for me to use some other implementations of internal web browsers - so please suggest some other approach we cannot add a listener to IWebBrowser.. Thanks for ur help !!

  • React to change on a static property

    - by Stiggler
    I'm re-writing an MXML item renderer in pure AS. A problem I can't seem to get past is how to have each item renderer react to a change on a static property on the item renderer class. In the MXML version, I have the following binding set up on the item renderer: instanceProperty={callInstanceFunction(ItemRenderer.staticProperty)} What would be the equivalent way of setting this up in AS (using BindingUtils, I assume)? UPDATE: So I thought the following wasn't working, but it appears as if Flex is suppressing errors thrown in the instanceFunction, making it appear as if the binding itself is bad. BindingUtils.bindSetter(instanceFunction, ItemRenderer, "staticProperty"); However, when instanceFunction is called, already initialized variables on the given instance are all null, which was the cause of the errors referenced above. Any ideas why this is?

  • T-SQL Re-Assigning Order Numbering

    - by Meltdown
    Say I have a table with a field called "ordernum" that denotes the order of a given set of rows. Now imagine that I delete one of these rows. What type of query would work best for re-assigning the order numbers so that they remain sequential? Here's an example: id group_id name ordernum active --------------------------------------------------- 0_____0______'Name1'___5__true 1_____0______'Name2'___4__true 2_____0______'Name3'___3__true 3_____1______'Name4'___2__true 4_____1______'Name5'__1__true 5_____1______'Name6'__NULL___false Now if I deleted the column with id='4' how would I reset the values in the 'ordernum' field for that specific group? Is this even possible? Or if I added a new row. (The first time the rows are created they are sorted by date, but then the user has the option to set the order himself.) In my table design I have a column 'active' boolean. If 'active' is set to false, then 'ordernum' is set to NULL. Otherwise it should be given an order number.

    I'm trying using LDAP to authenticate user, but I have a problem with LDAP.

  • C# System.IO.FileInfo gets virtual address which has sessions key

    - by Anicho
    Okay so the following line returns null because its path cannot be found: System.IO.FileInfo fi = di.GetFiles()[position]; What I am currently doing is: <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <ctl:Gallery runat="server" ID="Gallery1" FolderUrl="~/images/1/" Size="100" /> When this is invoked System.IO.FileInfo fi = di.GetFiles()[position]; it has the value similar to this: C:\Users\SomeUsername\Desktop\Tiamo\(S(mr1h0l55ycuixfbtqxbmttek))\images\1 Any idea how I can return the virtual path without actually having the session key in there? Thank you in advanced for any help you may give :) much appreciated.

  • DataTemplate defautl visibility for ContentControls

    - by bitbonk
    In my MVVM based WPF application I have a lot of different ViewModel types that dynamically loaded into ContentControls or ContentPresenters. Therefor I need to explictly set what DataTemplate is to be used in XAML: <ContentControl Content={Binding SomePropertyOfTypeViewModel} ContentTemplate={StaticResource someTemplate} /> Now my problem is that the content control is displaying the UI of someTemplate even if the ContentControl is bound to nothing (i.e ViewModel.SomePropertyOfTypeViewModel is null) Is there a quick and easy way to make all ContentControls display nothing if they are currently bound to nothing? When I use implicit DataTemplates everything works as expected. Unfortunately I can't use this mechanism here.

  • How return 304 status with FileResult in ASP.NET MVC RC1

    - by Maysam
    As you may know we have got a new ActionResult called FileResult in RC1 version of ASP.NET MVC. Using that, your action methods can return image to browser dynamically. Something like this: public ActionResult DisplayPhoto(int id) { Photo photo = GetPhotoFromDatabase(id); return File(photo.Content, photo.ContentType); } In the HTML code, we can use something like this: <img src="http://mysite.com/controller/DisplayPhoto/657"> Since the image is returned dynamically, we need a way to cache the returned stream so that we don't need to read the image again from database. I guess we can do it with something like this, I'm not sure: Response.StatusCode = 304; This tells the browser that you already have the image in your cache. I just don't know what to return in my action method after setting StatusCode to 304. Should I return null or something?

  • adldap class, need to search for user in two groups

    - by Brad
    http://adldap.sourceforge.net/wiki/doku.php?id=api_user_functions#user_ingroup_username_group_recursive_null I am using the adLDAP class above to authenticate users against our ldap server. I was wondering how I could check multiple groups to see if the user belongs to either, if they belong to either. I don't know if user_ingroup($username,$group,$recursive=NULL); can handle search two different groups for the user, need help coding it to search for the user in two different groups, and as soon as it finds it in one of those, break the operation and set a variable to true. Any help is appreciated.

  • Why & When should I use SPARSE COLUMN? (SQL SERVER 2008)

    - by priyanka.sarkar
    After going thru some tutorials on SQL SERVER 2008's new feature SPARSE COLUMN, I have found that it doesn't take any space if the column value is 0 or null but when there is a value, it takes 4 times the space a regular(non sparse) column holds. If my understanding is correct, then why I will go for that at the time of database design? And if I use that, then at what situation so I be? Also out of curiosity, how come no space get's reserve when a column is defined as sparse column(I mean to say, what is the internal implementation for that) Thanks in advance

The code is like this: <% if (TempData["errorMsg"] != null) { %> <h2><%= TempData["errorMsg"]%></h2> <% } %>

  • how can I retrieve an html document from a url from javascript?

    - by Matt
    Hi, I have a url and I want to retrieve the html dom generated when going to the url (all the code for the page) in a javascript variable. How can I do this? I'm guessing an html get or post? Can anyone give an example with jQuery? Every time I do a $.get or $.post like this: $.get("http://www.google.ca", function(result) { alert(result); alert($(result).html()); }); $.post("http://www.google.ca", function(result) { alert(result); alert($(result).html()); }, "xml"); the first alert in each call comes up blank and the second comes up as null. Any ideas? Thanks, Matt

  • SQL for selecting only the last item from a versioned table

    - by Jeremy
    I have a table with the following structure: CREATE TABLE items ( id serial not null, title character varying(255), version_id integer DEFAULT 1, parent_id integer, CONSTRAINT items_pkey PRIMARY KEY (id) ) So the table contains rows that looks as so: id: 1, title: "Version 1", version_id: 1, parent_id: 1 id: 2, title: "Version 2", version_id: 2, parent_id: 1 id: 3, title: "Completely different record", version_id: 1, parent_id: 3 This is the SQL code I've got for selecting out all of the records with the most recent version ids: select * from items inner join ( select parent_id, max(version_id) as version_id from items group by parent_id) as vi on items.version_id = vi.version_id and items.parent_id = vi.parent_id Is there a way to write that SQL statement so that it doesn't use a subselect?

    Hello, I have a Silverlight application in which I implemented MVVM pattern. In my application there is a child window on which I have ComboBox.

When my window is loaded I set values to this properties. But my combobox doesn't display selected item. I found that when I set property which is bound to selected item (in ViewModel), the PropertyChanged event is null. Can anyone help me. Thanks.

  • sOperator as and generic classes

    - by abatishchev
    I'm writing .NET On-the-Fly compiler for CLR scripting and want execution method make generic acceptable: object Execute() { return type.InvokeMember(..); } T Execute<T>() { return Execute() as T; /* doesn't work: The type parameter 'T' cannot be used with the 'as' operator because it does not have a class type constraint nor a 'class' constraint */ // also neither typeof(T) not T.GetType(), so on are possible return (T) Execute(); // ok } But I think operator as will be very useful: if result type isn't T method will return null, instead of an exception! Is it possible to do?

  • Unable to incorporate Eclispe JDT codeAssist facilities outside a Plug-in

    - by shi kui
    Using Eclipse jdt facilities, you can traverse the AST of java code snippets as follows: ASTParser ASTparser = ASTParser.newParser(AST.JLS3); ASTparser.setSource("package x;class X{}".toCharArray()); ASTparser.createAST(null).accept(...); But when trying to perform code complete & code selection it seems that I have to do it in a plug-in application since I have to write codes like IFile file = ResourcesPlugin.getWorkspace().getRoot().getFile(new Path(somePath)); ICodeAssist i = JavaCore.createCompilationUnitFrom(f); i.codeComplete/codeSelect(...) Is there anyway that I can finally get a stand-alone java application which incorporates the jdt code complete/select facilities? thx a lot! shi kui

  • How do I check if a user is a fan of my facebook page on my website?

    - by Tony
    I want to check if my users are fans of my facebook page. I think something like this should do it: <script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US"></script> <script type="text/javascript">FB.init("my api key","xd_receiver.htm");</script> <script type="text/javascript"> //<![CDATA[ FB_RequireFeatures(["Api"], function(){ var api = FB.Facebook.apiClient; api.pages_isFan(PAGE_ID,gigyaUser.FACEBOOK_USER_ID,function(response){ alert(response); }); }); //]]> </script> However, for some reason I keep getting null even though the user is in fact a fan of the page. Am I missing something?

  • Is POSTing a Dictionary to an .NET MVC action possible?

    - by Brenton Alker
    I have a form which contains a series of fields like: <input type="text" name="User[123]" value="Alice" /> <input type="text" name="User[456]" value="Bob" /> ... Where the index of the User array (123 and 456) are ID's associated with the value. I'm trying to update these values in the controller. My thinking is that a Dictionary that maps ID to name would work, but creating the action like: public void Save(Dictionary<string, string> user) { // ... } results in the user parameter being null. So, is passing a Dictionary possible? or, is there another method to achieve this?

  • JSF2 - Why does render response not rerender component setting?

    - by fekete-kamosh
    From the tutorial: "If the request is a postback and errors were encountered during the apply request values phase, process validations phase, or update model values phase, the original page is rendered during Render response phase" (http://java.sun.com/javaee/5/docs/tutorial/doc/bnaqq.html) Does it mean that if view is restored in "Restore View" phase and then any apply request/validation/update model phase fails and skips to "Render response" that Render response only passes restored view without any changes to client?

  • Confusion about MVC Routes

    - by yang
    What is the problem below? routes.MapRoute( "Default2", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "test" } // Parameter defaults ); routes.MapRoute( "Default1", // Route name "{controller}/{action}/{name}", // URL with parameters new { controller = "Home", action = "Report", name = "" } // Parameter defaults ); When I navigate to /home/index "id" parameter takes the default value of "test" but when I navigate to home/report the name parameter is null. In short, if the route definition is the first in the route table, then the parameter takes its default value. But the others below don't.
