  • Validating a wrong date entry in rich faces

    - by Hiral Lakdavala
    Hi, (On behalf of a collegue) In one of our functionality we have some date fields for inline edit where we have enabled manual input. If in rich:calendar component, we manually enter improper date or junk data it will not even call the action method. As per our requirement we need to display an error message for date validation for these kind of fields. Is there any way to track that the date entered in the calendar field is improper with this component. Code for the reference: <rich:calendar id="actualOpeningDtCal" rendered="#{!empty storeProgram.id}" value="#{storeProgram.actualOpeningDate}" placeholder="dd-mmm-yyyy" inputSize="20" enableManualInput="true" datePattern="dd-MMM-yyyy" buttonIcon="../content/images/calendar.png" showWeeksBar="false" showFooter="false"> <a4j:support event="oninputblur" reRender="aList" ajaxSingle="false" action="#{aController.inlineEdit}"> <f:setPropertyActionListener value="#{aProgram}" target="#{aController.inLineEditaBean}" /> </a4j:support> <a4j:support event="oncollapse" reRender="aList" ajaxSingle="false" action="#{aController.inlineEdit}"> <f:setPropertyActionListener value="#{aProgram}" target="#{aController.inLineEditaBean}" /> </a4j:support> </rich:calendar> Regards, Hiral

  • Exception loading CustomMeta from Tridion Broker Service (2009 SP1)

    - by Rob Stevenson-Leggett
    I am trying to load some Custom Meta from a component which is published into the Tridion Broker. This is 2009 SP1 I can see the component in the Custom_Meta table with a query like: SELECT * FROM [Tridion_Broker].[dbo].[CUSTOM_META] WHERE ITEM_ID = 204221 However using the below code, I get a Java Runtime exception. string queryStringId = HttpUtility.UrlDecode(Request.QueryString["component_uri"]); string pageId = ((BasePage) Page).PageTcmId; int publicationId = int.Parse(pageId.Split(':')[1].Split('-')[0]); using (var cmf = new ComponentMetaFactory(publicationId)) { IComponentMeta cm = cmf.GetMeta(queryStringId); if(cm != null) { VideoId = cm.CustomMeta.GetValue("video_url").ToString(); } else { litMessage.Visible = true; } } Stack trace: [RuntimeException] Codemesh.JuggerNET.NTypeValue.Throw(Int64 inst) +351 Codemesh.JuggerNET.JavaClass.ThrowTypedException(Int64 inst) +1278 Codemesh.JuggerNET.JavaMethod.CallObject(JavaProxy jpo, JavaMethodArguments args) +551 Codemesh.JuggerNET.JavaMethod.CallObject(JavaProxy jpo, Type declaredType, Boolean bLeaf, JavaMethodArguments jargs) +50 Com.Tridion.Meta.ComponentMetaFactory.GetMeta(Int32 componentId) +118 Tridion.ContentDelivery.Meta.ComponentMetaFactory.GetMeta(Int32 componentId) +16 ASP._controls_video_ascx.Page_Load(Object sender, EventArgs args) in c:\Inetpub\wwwroot\borland\us\_controls\Video.ascx:18 System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14 System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +35 System.Web.UI.Control.OnLoad(EventArgs e) +99 System.Web.UI.Control.LoadRecursive() +50 System.Web.UI.Control.LoadRecursive() +141 System.Web.UI.Control.LoadRecursive() +141 System.Web.UI.Control.LoadRecursive() +141 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627

  • Is there anyway to close a StreamWriter without closing it's BaseStream?

    - by Binary Worrier
    My root problem is that when using calls Dispose on a StreamWriter, it also disposes the BaseStream (same problem with Close). I have a workaround for this, but as you can see it involves copying the stream. Is there any way to do this without copying the stream? The purpose of this is to get the contents of a string (originally read from a database) into a stream, so the stream can be read by a third party component. NB I cannot change the third party component. public System.IO.Stream CreateStream(string value) { var baseStream = new System.IO.MemoryStream(); var baseCopy = new System.IO.MemoryStream(); using (var writer = new System.IO.StreamWriter(baseStream, System.Text.Encoding.UTF8)) { writer.Write(value); writer.Flush(); baseStream.WriteTo(baseCopy); } baseCopy.Seek(0, System.IO.SeekOrigin.Begin); return baseCopy; } Used as public void Noddy() { System.IO.Stream myStream = CreateStream("The contents of this string are unimportant"); My3rdPartyComponent.ReadFromStream(myStream); } Ideally I'm looking for an imaginery method called BreakAssociationWithBaseStream, e.g. public System.IO.Stream CreateStream_Alternate(string value) { var baseStream = new System.IO.MemoryStream(); using (var writer = new System.IO.StreamWriter(baseStream, System.Text.Encoding.UTF8)) { writer.Write(value); writer.Flush(); writer.BreakAssociationWithBaseStream(); } return baseStream; }

  • Which java web technology to learn to develop Rich Internet Applications ?

    - by Cshah
    Hi, I have developed web applications using JSF (myfaces components). But in these days of responsive UI, JSF doesnt fare well. I m hearing a lot about AJAX, GWT, etc. So i wanted your opinion on which web technology/framework should i learn inorder to develop web applications for enterprise products. Some of the web technologies that i m hearing are: ICE Faces (With AJAX Bridge support) GWT extJS and extGWT JavaFX Apache Wicket Jquery AJAX Open laszlo Which of the above or the combination of the above would help me ? Some of the parameters on which you can rate these web technologies are: Ease of learning Maintainability of web application code Community support IDE support - Eclipse or NetBeans Off the shelf component availability (like textbox,table grids, option menus) License - Does it cost for commercial use ? User Experience - responsive UI. Shouldnt be sluggish A similar question on SO does answer my question partially. Would want more info though. EDIT: Answers collated: Based on the answers : AJAX would be the best thing to start for learning fundamentals, then learn JQUERY. Any component based frame work that can complement ajax,jquery ? Edit 2: If i had to design a web application like StackOverFlow (in java platform) which would be the best choice to learn and adopt? Wicket + Jquery, WiQuery GWT Some XYZ Faces technology(RichFaces/ICEFaces) + AJAX. Comments appreciated from some one who has worked with them and can rate them in the above mentioned parameters.

  • Installing sfJqueryTreeDoctrineManagerPlugin to Symfony 1.4

    - by Christine Q.
    I have faced serious difficulties while installing sfJqueryTreeDoctrineManagerPlugin to Symfony 1.4 w/ Doctrine ORM. The installation directly from the server did not work out like with previous plugins that I have installed: C:\pathsymfony plugin:install sfJqueryTreeDoctrineManagerPlugin plugin installing plugin "sfJqueryTreeDoctrineManagerPlugin" No release available for plugin "sfJqueryTreeDoctrineManagerPlugin" This is why I needed to install the plugin by downloading the tgz-archive and install it manually like this: C:\pathsymfony plugin:install "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz" plugin installing plugin "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz" sfSymfonyPluginManager Installing web data for plugin I guess everything should be fine this far? After that I edited \apps\admin\config\settings.yml like instructed in the plugins readme file. all: .settings: enabled_modules: [default, sfJqueryTreeDoctrineManager] I also checked that the plugin was enabled in \config\ProjectConfiguration.class.php like this: $this->enablePlugins(array( // other plugins, 'sfJqueryTreeDoctrineManagerPlugin' )); I published assets and cleared cache: C:\pathsymfony plugin:publish-assets >> plugin Configuring plugin - sfJqueryTreeDoctrineManagerPlugin C:\pathsymfony cc Finally I added the required helper to the newly created apps\admin\modules\category\templates\indexSuccess.php <?php use_helper("sfJqueryTreeDoctrine"); echo get_nested_set_manager("Category", "name"); When loading the page I unfortunately get the following error: 500 | Internal Server Error | InvalidArgumentException Unable to load "sfJqueryTreeDoctrineHelper.php" helper in: SF_ROOT_DIR\apps\admin\modules/businessunitgroup/lib/helper, SF_ROOT_DIR\apps\admin\lib/helper, SF_ROOT_DIR\lib/helper, SF_SYMFONY_LIB_DIR/helper. The file sfJqueryTreeDoctrineHelper.php exists indeed but not in any previously mentioned folder. The file can only be found in the folder \plugins\sfJqueryTreeDoctrineManagerPlugin\lib\helper. I guess that Symfony doesn't look to that folder while finding helpers? I have tried to move the helper file to one of the previously mentioned folders. As expected, that changes the error. Now I get: 500 | Internal Server Error | sfConfigurationException The component does not exist: "sfJqueryTreeDoctrineManager", "manager". Unfortunately I can't figure out how should I be able to retrieve the "missing" component from the correct folder. I would be very grateful for any advice to help me forward. By the way, I am aware that there are other nested-set / tree plugins available for Symfony (like sfDoctrineTreePlugin and caPropelTreePlugin) but unluckily those are either uncompatible or too limited for my needs.

  • Windows 7 theme for WPF?

    - by DanM
    Is there any way to make a WPF app look like it's running on Windows 7 even if it's running on XP? I'm looking for some kind of theme I can just paste in. I'm aware of the themes project on Codeplex (http://www.codeplex.com/wpfthemes), but it lacks support for DataGrid, which is something I critically need. I was thinking maybe the Windows 7 theme would just be an easy port, or exists in some file somewhere already. Any information you have (even if it's bad news) would be much appreciated. Update Using @Lars Truijens idea, I was able to get the Windows 7 look for the major controls, but unfortunately it did not work for the WPF Toolkit DataGrid control, which I need. DataGrid looks like this with Aero theme DataGrid should look like this So, I'm still looking for a solution to this problem if anyone has any ideas. Maybe someone has built an extension to the Aero theme that covers the WPF toolkit controls? Again, any information you have is much appreciated. Update 2 - Problem solved! To get the Aero theme to work with WPF Toolkit controls, you just need to add a second Aero dictionary, so your App.xaml should now look like this. <Application.Resources> ... <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/PresentationFramework.Aero;component/themes/Aero.NormalColor.xaml" /> <ResourceDictionary Source="pack://application:,,,/WPFToolkit;component/Themes/Aero.NormalColor.xaml" /> ... </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> Also, I would recommend turning the gridlines off in your DataGrid controls (because they look horrible): <DataGrid GridLinesVisibility="None" ...>

  • Draw LINE_STRIP with Unity

    - by Boozzz
    For a new project I am thinking about whether to use OpenGL or Unity3d. I have a bit of experience with OpenGL, but I am completely new to Unity. I already read through the Unity documentation and tutorials on the Unity Website. However, I could not find a way to draw a simple Line-Strip with Unity. In the following example (C#, OpenGL/SharpGL) I draw a round trajectory from a predifined point to an obstacle, which can be imagined as a divided circle with midpoint [cx,cy] and radius r. The position (x-y coordinates) of the obstacle is given by obst_x and obst_y. Question 1: How could I do the same with Unity? Question 2: In my new project, I will have to draw quite a lot of such geometric primitives. Does it make any sense to use Unity for those things? void drawCircle(float cx, float cy, float r, const float obst_x, const float obst_y) { float theta = 0.0f, pos_x, pos_y, dist; const float delta = 0.1; glBegin(GL_LINE_STRIP); while (theta < 180) { theta += delta; //get the current angle float x = r * cosf(theta); //calculate the x component float y = r * sinf(theta); //calculate the y component pos_x = x + cx; //calculate current x position pos_y = y + cy; //calculate current y position //calculate distance from current vertex to obstacle dist = sqrt(pow(pos_x - obst_x) + pow(pos_y - obst_y)); //check if current vertex intersects with obstacle if dist <= 0 { break; //stop drawing circle } else { glVertex2f(pos_x, pos_y); //draw vertex } } glEnd(); }

  • WiX: Define made in included file not avaible from wxs-fragment-file.

    - by leiflundgren
    I have a defines.wxi-file which contains some good definitions used in all my wxs-files. When I attempt to reference the defined value from one of the <Fragment>-files I get Undefined preprocessor variable '$(var.IMAGE_FOLDER)' back in my face. I guess there is something trivial I am missing here... Any ideas? Edit 19:th April. Found that issue only occurs if reference from a Fragment-file. Re-wrote sample to match that. defines.wxi <Include> <?define IMAGE_FOLDER="Images" ?> </Include> some-Fragment.wxs <Fragment> <?Include defines.wxi ?> <Component Id='c.Images' Guid=".." Directory='INSTALLDIR.Images' > <File Id='f.sample.jpg' Source='$(var.IMAGE_FOLDER)sample.jpg' Name='sample.jpg' /> </Component>

  • Create Folders from text file and place dummy file in them using a CustomAction

    - by Birkoff
    I want my msi installer to generate a set of folders in a particular location and put a dummy file in each directory. Currently I have the following CustomActions: <CustomAction Id="SMC_SetPathToCmd" Property="Cmd" Value="[SystemFolder]cmd.exe"/> <CustomAction Id="SMC_GenerateMovieFolders" Property="Cmd" ExeCommand="for /f &quot;tokens=* delims= &quot; %a in ([MBSAMPLECOLLECTIONS]movies.txt) do (echo %a)" /> <CustomAction Id="SMC_CopyDummyMedia" Property="Cmd" ExeCommand="for /f &quot;tokens=* delims= &quot; %a in ([MBSAMPLECOLLECTIONS]movies.txt) do (copy [MBSAMPLECOLLECTIONS]dummy.avi &quot;%a&quot;\&quot;%a&quot;.avi)" /> These are called in the InstallExecuteSequence: <Custom Action="SMC_SetPathToCmd" After="InstallFinalize"/> <Custom Action="SMC_GenerateMovieFolders" After="SMC_SetPathToCmd"/> <Custom Action="SMC_CopyDummyMedia" After="SMC_GenerateMovieFolders"/> The custom actions seem to start, but only a blank command prompt window is shown and the directories are not generated. The files needed for the customaction are copied to the correct directory: <Directory Id="WIX_DIR_COMMON_VIDEO"> <Directory Id="MBSAMPLECOLLECTIONS" Name="MB Sample Collections" /> </Directory> <DirectoryRef Id="MBSAMPLECOLLECTIONS"> <Component Id="SampleCollections" Guid="C481566D-4CA8-4b10-B08D-EF29ACDC10B5" DiskId="1"> <File Id="movies.txt" Name="movies.txt" Source="SampleCollections\movies.txt" Checksum="no" /> <File Id="series.txt" Name="series.txt" Source="SampleCollections\series.txt" Checksum="no" /> <File Id="dummy.avi" Name="dummy.avi" Source="SampleCollections\dummy.avi" Checksum="no" /> </Component> </DirectoryRef> What's wrong with these Custom Actions or is there a simpler way to do this?

  • Castle Windsor, Fluent Nhibernate, and Automapping Isession closed problem

    - by SImon
    I'm new to the whole castle Windsor, Nhibernate, Fluent and Automapping stack so excuse my ignorance here. I didn't want to post another question on this as it seems there are already a huge number of questions that try to get a solution the Windsor nhib Isession management problem, but none of them have solved my problem so far. I am still getting a ISession is closed exception when I'm trying to call to the Db from my Repositories,Here is my container setup code. container.AddFacility<FactorySupportFacility>() .Register( Component.For<ISessionFactory>() .LifeStyle.Singleton .UsingFactoryMethod(() => Fluently.Configure() .Database( MsSqlConfiguration.MsSql2005. ConnectionString( c => c.Database("DbSchema").Server("Server").Username("UserName").Password("password"))) .Mappings ( m => m.AutoMappings.Add ( AutoMap.AssemblyOf<Message>(cfg) .Override<Client>(map => { map.HasManyToMany(x => x.SICCodes).Table("SICRefDataToClient"); }) .IgnoreBase<BaseEntity>() .Conventions.Add(DefaultCascade.SaveUpdate()) .Conventions.Add(new StringColumnLengthConvention(),new EnumConvention()) .Conventions.Add(new EnumConvention()) .Conventions.Add(DefaultLazy.Never()) ) ) .ExposeConfiguration(ConfigureValidator) .ExposeConfiguration(BuildDatabase) .BuildSessionFactory() as SessionFactoryImpl), Component.For<ISession>().LifeStyle.PerWebRequest.UsingFactoryMethod(kernel => kernel.Resolve<ISessionFactory>().OpenSession() )); In my repositories i inject private readonly ISession session; and use it as followes public User GetUser(int id) { User u; u = session.Get<User>(id); if (u != null && u.Id > 0) { NHibernateUtil.Initialize(u.UserDocuments); } return u; in my web.config inside <httpModules>. i have also added this line <add name="PerRequestLifestyle" type="Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule, Castle.Windsor"/> I'm i still missing part of the puzzle here, i can't believe that this is such a complex thing to configure for a basic need of any web application development with nHibernate and castle Windsor. I have been trying to follow the code here windsor-nhibernate-isession-mvc and i posted my question there as they seemed to have the exact same issue but mine is not resolved.

  • Signals and Variables in VHDL (order) - Problem

    - by Morano88
    I have a signal and this signal is a bitvector (Z). The length of the bitvector depends on an input n, it is not fixed. In order to find the length, I have to do some computations. Can I define a signal after defining the variables ? It is giving me errors when I do that. It is working fine If I keep the signal before the variables (that what is showing below) .. but I don't want that .. the length of Z depends on the computations of the variables. What is the solution ? library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; entity BSD_Full_Comp is Generic (n:integer:=8); Port(X, Y : inout std_logic_vector(n-1 downto 0); FZ : out std_logic_vector(1 downto 0)); end BSD_Full_Comp; architecture struct of BSD_Full_Comp is Component BSD_BitComparator Port ( Ai_1 : inout STD_LOGIC; Ai_0 : inout STD_LOGIC; Bi_1 : inout STD_LOGIC; Bi_0 : inout STD_LOGIC; S1 : out STD_LOGIC; S0 : out STD_LOGIC ); END Component; Signal Z : std_logic_vector(2*n-3 downto 0); begin ass : process Variable length : integer := n; Variable pow : integer :=0 ; Variable ZS : integer :=0; begin while length /= 0 loop length := length/2; pow := pow+1; end loop; length := 2 ** pow; ZS := length - n; wait; end process; end struct;

  • getting a tiled image collection on the iPad (deepzoom)

    - by Chris B
    I have a set of tiled image collections created via microsoft's deep zoom composer, and a silverlight app that currently consumes them for display via MultiScaleImage - it's all working pretty well - I'd just like to get some experience with iPad programming and have a couple of ideas for some ipad applications. All my ideas rely on me being able to display/manipulate these tiled image sets (on the iPad). I just picked up a iMac to facilitate this. I'm not seeing any objective-c / cocoa-touch libraries for this though, so am assuming I will have to roll my own. (Saw the seadragon ajax component, which is pretty slick, but I'm dealing with collections here, which it doesn't support. I would also like to roll this as a native app just to get the experience). The only open source project I found for displaying/manipulating the tiled image sets was Openzoom -a flash component. I'm not to familiar with actionscript either (python, java, c#, and c are the only languages I have really used), but briefly inspecting the code I didn't really have any issues with it and can probably use it for hints on how to swap the tiles in and out, etc.. But, as I'm pretty new to obj-c/cocoa-touch, some pointers in the right direction would be appreciated. 1) Are there any other projects out there I am missing, or is openzoom my best bet for some reference? 2) Should I be trying to do this display in the UIKit framework, or should I do it as an OpenGL display? 3) Any other suggestions/pointers that I didn't think to ask.

  • Controlling the order of PicoContainer startup

    - by Trejkaz
    I have been tasked with doing some refactoring work on how we start up applications. Basically we have a bunch of console apps which were depending on the GUI application startup code, causing bogus dependencies which have kick-on effects for which libraries we need to ship, and which dependencies other modules need to declare. So I have written a simple startup framework where I basically just throw a bunch of Runnable objects into a list and then run them in order - and it works. But I was thinking - we already have PicoContainer in our project, so all these things that need to be run on startup could potentially be thrown into a PicoContainer, and if they implement Startable they will start... But in some cases we want to specify the ordering between them. For example, I don't want any other component writing to the log before we write a header into the log indicating that the application is starting up. I know I can introduce ordering by introducing injection dependencies, but this feels like a hack in this case - I would need to add the log header writer as a dependency for every other component which might write to the log, which isn't great at all. Nonetheless it seems like it would be nice to control the order of PicoContainer startup, so is there perhaps some other way? Alternatively I could just keep it simple and stick to my list of Runnable. It does, after all, work.

  • how to update the table in sql database from a Paradox DB table using delphi

    - by Sreenath Krishnakumar
    I am doing a project in Delphi6 which enables the user to update the table in SQL server database ; if there is any changes in the table of Paradox DB. An update button has been created and whenever the user clicks it, all the changes made in the paradox db table have to be updated in the SQL server table. Only if there is any changes the table need to be updated else ; it should close automatically. For that I have created a table, "Schedule" ,both in Paradox DB and SQL server. But I am stuck with this Paradox DB thing. Which component can I drop in the form for connecting the table in Paradox DB ? For SQL server I used ado table component. For this Paradox also can I use that ? I am not a regular programmer so I am not well versed this Delphi6 also. So I am seeking a help for this. Can anybody give me an example coding also ?

  • Add ability to provide list items to composite control with DropDownLIst

    - by Kyle
    I'm creating a composite control for a DropDownList (that also includes a Label). The idea being that I can use my control like a dropdown list, but also have it toss a Label onto the page in front of the DDL. I have this working perfectly for TextBoxes, but am struggling with the DDL because of the Collection (or Datasource) component to populate the DDL. Basically I want to be able to do something like this: <ecc:MyDropDownList ID="AnimalType" runat="server" LabelText="this is what will be in the label"> <asp:ListItem Text="dog" Value="dog" /> <asp:ListItem Text="cat" Value="cat" /> </ecc:MyDropDownList> The problem is, I'm not extending the DropDownList class for my control, so I can't simply work it with that magic. I need some pointers to figure out how I can turn my control (MyDropDownList), which is currently just a System.Web.UI.UserControl, into something that will accept List items within the tag and ideally, I'd like to be able to plug it into a datasource (the same functions that the regular DDL offers). I tried with no luck just extending the regular DDL, but couldn't get the Label component to fly with it.

  • Passing Key-Value pair to a COM method in C#

    - by Sinnerman
    Hello, I have the following problem: I have a project in C# .Net where I use a third party COM component. So the problem is that the above component has a method, which takes a string and a number of key-value pairs as arguments. I already managed to call that method through JavaScript like that: var srcName srcName = top.cadView.addSource( 'Database', { driver : 'Oracle', host : '10.10.1.123', port : 1234, database : 'someSID', user : 'someuser', password : 'somepass' } ) if ( srcName != '' ) { ... } ... and it worked perfectly well. However I have no idea how to do the same using C#. I tried passing the pairs as Dictionary and Struct/Class but it throws me a "Specified cast is not valid." exception. I also tried using Hashtable like that: Hashtable args = new Hashtable(); args.Add("driver", "Oracle"); args.Add("host", "10.10.1.123"); args.Add("port", 1234); args.Add("database", "someSID"); args.Add("user", "someUser"); args.Add("password", "samePass"); String srcName = axCVCanvas.addSource("Database", args); and although it doesn't throw an exception it still won't do the job, writing me in a log file [ Error] [14:38:33.281] Cad::SourceDB::SourceDB(): missing parameter 'driver' Any help will be appreciated, thanks.

  • how to do these in visio 2007?

    - by user285825
    I am very annoyed with this software. I am unable to do many things with this software. In the book 'UML distilled' many features of UML are discussed which I am not sure how to accomplish with visio 2007. For instance, 1) I can't find the unary association. In the UML static structure under shapes panel on left, there are a lot of components like package, class, blah, blah, binary association, blah, blah, association class. But where is unary association. 2) For sequence diagram, I created a message (any of sync, async, call type message, ordinary message). The I tried to incorporate some parameter information. I went to the properties. There were a category called arguments. But selecting that shows a table where arguments are supposed to be shown. But all are diasbled. 3) For sequence diagram, there is no component delete (the big X) in the UML Sequence. 4) For class diagram, there is supposed to be a comment compartment where comments like mentioning the responsibilities are allowed using a comment prefixed with "--". But I am not sure how to accomplish them. 5) there is also supposed to be a way to indicate static properties of a class. But I am not sure how to do that in visio. 6) there is supposed to be a stereotype for class <. But in the stereotype drop down there is no stereotype. 7) where is the ball and socket component?

  • I need a true mouseOver...

    - by invertedSpear
    Ok, so mouseOver and RollOver, and their respective outs work great as long as your mouse is actually over the item, or one of it's children. My problem is that I may have another UI component "between" my mouse and the item I want to process the mouse/rollover(maybe a button that is on top of a canvas, but is not a child of the canvas). The mouse is still over the component, there's just something else that it's over at the same time. Any tips or help how to deal with this? Let me know if I'm not being clear enough. Here is a simplified code example detailing my question copy/paste that into your flex/flash builder and you'll see what I mean: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="500" height="226" creationComplete="ccInit()"> <mx:Script> <![CDATA[ private function ccInit():void{ myCanv.addEventListener(MouseEvent.ROLL_OVER,handleRollOver); } private function handleRollOver(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",1); myCanv.addEventListener(MouseEvent.ROLL_OUT,handleRollOut); } private function handleRollOut(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",0); myCanv.removeEventListener(MouseEvent.ROLL_OUT,handleRollOut); } ]]> </mx:Script> <mx:Canvas id="myCanv" x="10" y="10" width="480" height="200" borderStyle="solid" borderColor="#000000" backgroundColor="#FFFFFF" backgroundAlpha="0"> </mx:Canvas> <mx:Button x="90" y="50" label="Button" width="327" height="100"/> </mx:Application>

I don't get this error for this line of code in a pure Windows Phone 8 project, and I don't get it in a Windows Store app either so I don't understand why it won't work in my PCL. The GetAwaiter is an extension method in the class WindowsRuntimeSystemExtensions which is in System.Runtime.WindowsRuntime.dll. Using the Object Browser I can see this dll is available in the .NET for Windows Store apps component set and in the Windows Phone 8 component set but not in the .NET Portable Subset. I just don't understand why it wouldn't be in the Portable Subset if it's available in both my targeted platforms.

  • Flex Spark TitleWindow bad redraw on dragging

    - by praksant
    Hi, I have a problem with redrawing in flex 4. I have a spark titleWindow, and if i drag it faster, it looks like it's mask is one frame late after the component. it's easily visible with 1pixel thin border, because it becomes invisible even with slower movement. You can try it here (what is not my page, but it's easier to show you here than uploading example): http://flexponential.com/2010/01/10/resizable-titlewindow-in-flex-4/ If you move in direction up, you see disappearing top border. in another directions it's not that sensitive as it has wide shadow, and it's not very visible on shadow. On my computer i see it on every spark TitleWindow i have found on google, although it's much less visible with less contrast skins, without borders or with shadows. Do you see it there? i had never this problem with halo components. It's doing the same thing with different skins. I tried to delete masks from skin, cache component, skin even an application as bitmap with no success. I also turned on redraw regions in flash player, and it looks like it's one frame late after titlewindow too. Does anyone know why is it doing this or how can i prevent it? Thank you UPDATE: no answers? really?

  • Is there a way to trace through only project source in Delphi?

    - by Justin
    I'm using Delphi 2010 and I'm wondering if there's a way to trace through code which is in the project without tracing through calls to included VCLs. For example - you put in a breakpoint and then use Shift+F7 to trace through line-by-line. Now you run into a call to some lengthy procedure in a VCL - in my case it's often a Measurement Studio or other component that draws the doodads for a bunch of I/O, OPC, or other bits. At any rate, what happens is that the debugger hops out of the active source file, opens the component source, and traces through that line by line. Often this is hundreds or thousands of lines of code I don't care about - I just want to have it execute and return to the next source line in MY project. Obviously you can do this by setting breakpoints around every instance of an external call, but often there are too many to make this practical - I'd be spending an hour setting a hundred breakpoints every time I wanted to step through a section of code. Is there a setting or a tool somewhere that can do this? Allow one to trace through code within the project while silently executing code which is external to the project? Thanks in advance, Stack Overflow!

  • Systems design question: DB connection management in load-balanced n-tier

    - by aoven
    I'm wondering about the best approach to designing a DB connection manager for a load-balanced n-tier system. Classic n-tier looks like this: Client -> BusinessServer -> DBServer A load-balancing solution as I see it would then look like this: +--> ... +--+ +--> BusinessServer +--+--> SessionServer --+ Client -> Gateway --+--> BusinessServer +--| +--> DBServer +--> BusinessServer +--+--------------------+ +--> ... +--+ As pictured, the business server component is being load-balanced via multiple instances, and a hardware gateway is distributing the load among them. Session server probably needs to be situated outside the load-balancing array, because it manages state, which mustn't be duplicated. Barring any major errors in design so far, what is the best way to implement DB connection management? I've come up with a couple of options, but there may be others I'm not aware of: Introduce a new Broker component between the DBServer and the other components and let it handle the DB connections. The upside is that all the connections can be managed from a single point, which is very convenient. The downside is that now there is an additional "single point of failure" in the system. Other components must go through it for every request that involves DB in some way, which also makes this a bottleneck. Move the DB connection management into BusinessServer and SessionServer components and let each handle its own DB connections. The upside is that there is no additional "single point of failure" or bottleneck components. The downside is that there is also no control over possible conflicts and deadlocks apart from what DBServer itself can provide. What else can be done? FWIW: Technology is .NET, but none of the vendor-specific stacks are used (e.g. no WCF, MSMQ or the like).

  • Trying to set PC clock programmatically just before Daylight Saving Time ends

    - by Moe Sisko
    To reproduce : 1) Add Microsoft.VisualBasic assembly to your project reference 2) Change PC timezone to : (GMT+10:00) Canberra, Melbourne, Sydney . Ensure PC is set to automatically adjust clock for daylight savings time. (For this timezone, daylight savings time ends at 3am on 4 Apr 2010.) 3) add following code : public void SetNewDateTime(DateTime dt) { Microsoft.VisualBasic.DateAndTime.Today = dt; // ignores time component Microsoft.VisualBasic.DateAndTime.TimeOfDay = dt; // ignores date component } private void button1_Click(object sender, EventArgs e) { DateTime dt = new DateTime(2010, 4, 5, 5, 0, 0); // XX SetNewDateTime(dt); // XX System.Threading.Thread.Sleep(500); DateTime dt2 = new DateTime(2010, 4, 4, 1, 0, 0); SetNewDateTime(dt2); } 4) When button 1 is clicked, the PC clock eventually shows 2am, whereas 1 am was expected. (If code marked at "XX" is removed, the clock sometimes shows the correct time of 1 am). Any idea what is happening ? (Or is there a more reliable way of setting the PC clock from C# code ?) TIA.

  • How to customize data points on a Flex graph?

    - by Jess
    I have an area graph and I'm looking to have the data points to be shown. I have a CircleItemRenderer, but this shows all of the datapoints in the default stroke and fill. 1) How do I customize the display of my CircleItemRenderer? (instead of it having an orange fill, how can I change the color? 2) How can I decide to show the node for specific data points but not for others? For example, in my .XML file that imports the data for the graph, I may have a variable show_data_point which is true or false. Here's the current code I have: <mx:AreaSeries yField="numbers" form="segment" displayName="area graph" areaStroke = "{darkblue}" areaFill="{blue}" > <mx:itemRenderer> <mx:Component> <mx:CircleItemRenderer/> </mx:Component> </mx:itemRenderer> </mx:AreaSeries> </mx:series> Thanks a lot for your help!
