• flash dynamic textfield, multiline and wordwrap acting funky.

  - by pfunc

  I have this weird thing happening with flash and a dynamic textfield. Basically, someone rolls over a marker on a map, and a tooltip pops up with a dynamic textfield. The textfield is set to multiline=true and wordwrap = true, and I defined a specific width of 160 pixels. The problem is, some of my text is jumping to the next line, some of it is just getting cut off. So if I have a line like "The Cat Jumped Over the Box", On one line I will see "The Cat Jumped" and on the next line I would see "the Box". It looks like it is masking out the "over" line and not pushing it to the next line. It's not doing this for everything, just some longer lines. This is a really weird bug and I have tried for 8 hours to get this fixed. Has anyone ran into this problem before?

• What initial modelling/design activities on Agile Projects do you do??

  - by dalton

  When developing an application using agile techniques, what if any initial modelling/architecture activities do you do, and how do you capture that knowledge?? I'm not after a bullet list about XP, Scrum, Crystal, DSDM..etc as I'm familiar with the methodologies. But what do you do above and beyond the guidance given by these. I find I work best by thinking the system through first, but also like the benefits of timeboxing, story cards, pairing, tdd. The closest thing I've seen so far is Scott Ambler's Initial Architecture Modelling, but was wondering what alternatives are used out there?

• Compiling ASP.Net 2.0 Application under .Net Framework 3.5 and Compiler reference Problems/errors .

  - by Steve Johnson

  Hi all I am converting an ASP.Net 2.0 Project to compile for .Net Framework 3.5 and facing the following compiler error for assembly reference... InternalXmlHelper.vb(9,0): error BC30560: 'ExtensionAttribute' is ambiguous in the namespace 'System.Runtime.CompilerServices'. It appears that there are duplicate assembly references one from 2.0 and the other from 3.5 but i have double checked it and its not the issue.. I have also googled around...with no success.. I have sure that i am doing some tiny mistake in additiona or removal of references,,,Is there any special thing that needs to be checked or done when compiling asp.net 2.0 project under .Net Framework 3.5 ? Kindly help. Thanks Regards

• SLES 9 vs. SLES 10

  - by Michael Covelli

  Are there any important change in how SLES 10 implements Tcp sockets vs. SLES 9? I have several apps written in C# (.NET 3.5) that run on Windows XP and Windows Server 2003. They've been running fine for over a year, getting market data from a SLES 9 machine using a socket connection. The machine was upgraded today to SLES 10 and its causing some strange behavior. The socket normally returns a few hundred or thousand bytes every second. But occasionally, I stop receiving data. Ten or more seconds will go by with no data and then Receive returns with a 10k+ bytes. And some buffer is causing data loss because the bytes I receive on the socket no longer make a correct packet. The only thing changed was the SLES 9 to 10 upgrade. And rolling back fixes this immediately. Any ideas?

• How to use the md5 hash?

  - by Ken

  Okay, so I'm learning php, html, and mysql to learn website development (for fun). One thing I still don't get is how to use md5 of sha1 hashes. I know how to hash the plain text, but say I want to make a login page. Since the password is hashed and can't be reversed, how would mysql know that the user-inserted password matches the hashed password in the database? Here is what I mean: $password = md5($_POST['password']); $query = ("INSERT INTO `users`.`data` (`password`) VALUES ('$password')"); I know that this snippet of script hashes the password, but how would I use this piece of code and make a login page? Any working examples would be great.

• Programmatically retrieve disconnected network adapter information in .NET

  - by Soo Wei Tan

  I have an application written in C# that needs to retrieve information like IP address, subnet mask from a disconnected network adapter. I've tried using various methods such as WMI and the .NET NetworkAdapter class but they don't return any useful data when the network adapter is disconnected. I'm pretty sure Windows keeps this information somewhere, since I can apply network settings using netsh and it appears correctly in the Control Panel. One thing that worked for me in XP was to parse the output of the netsh tool and it would return information even for a disconnected adapter. However, this doesn't seem to work on Windows 7. Win XP output: Configuration for interface "Local Area Connection 5" DHCP enabled: No IP Address: 169.254.0.128 SubnetMask: 255.255.255.0 InterfaceMetric: 0 Win7 output: Configuration for interface "Local Area Connection 2" DHCP enabled: No InterfaceMetric: 5 Any ideas?

• How do I make my drop down remain dropped down?

  - by counterbeing

  The site I'm currently working on is located at: http://counterbeing.com The problem I'm trying to solve is that when you run your mouse over the "Categories" button, the sub-menu items pop up, but then disappear before you can click them. I've tried a variety of things. For one thing, I was attempting to define the div that the sub menu items are wrapped in as something that will also trigger the animation, but that doesn't seem to work... Here is the javascript file I'm using to grab both layers. I have it divided into 2 layers because one of them is somewhat transparent. $(document).ready(function() { ($("div#CategoriesLink").hover(function(){ $("div#navdrop").animate({ top: "0px" }) $("div#CategoryButtonHolder").animate({ top: "0px" }) }); });

• Excel parsing (xls) date error

  - by tau-neutrino

  I'm working on a project where I have to parse excel files for a client to extract data. An odd thing is popping up here: when I parse a date in the format of 5/9 (may 9th) in the excel sheet, I get 39577 in my program. I'm not sure if the year is encoded here (it is 2008 for these sheets). Are these dates the number of days since some sort of epoch? Does anyone know how to convert these numbers to something meaningful? I'm not looking for a solution that would convert these properly at time of parsing from the excel file (we already have thousands of extracted files that required a human to select relevant information - re-doing the extraction is not an option).

• Why is LOGON_USER Server Variable is blank on New Windows / New Tab?

  - by Alex Papadimoulis

  We are noticing some very strange behavior on an installation of a .NET2-based webapp on Server 2008. Our app uses "old school" Integrated Windows Authentication and simply reads the LOGIN_USER server variable from the request collection. There's a good reason for this, but that's somewhat irrelevant to the question, since the underlying WindowsAuthentication code from ASP.NET does the same thing. Anyway... When you enter the URL in the browser, it loads up just fine and displays the username (from LOGIN_USER) no problem. When you click on a link within the web app, it loads the page just fine and authenticates without any problems. When you "hard refresh" (Ctrl-F5) it also works just fine. However, when you click "open in a new window" or "open in a new tab", the LOGON_USER variable is blank Any ideas? Am I missing some IIS7 setting somewhere? Tested clients are Windows 7 with IE8 or Windows XP with IE6.

• Dynamically creating GWT screens using Metadata?

  - by Francis Shanahan

  I have an AWT applet application that needs to be ported over to GWT. The applet screens are described in meta data and the applet renders each screen dynamically using reflection. We'd like the same thing in GWT/ExtGWT. I've built a working version of this ExtJS whereby the metadata is turned into ExtJS Screen configs in the form of JSON. The drawback with this approach is the "wiring" of controls to data needs to be written in Javascript. GWT is preferred since it'd be all Java code, no JS. Upon digging in it's possible to render the screens using GWT off the metadata using GWT.create(). The problem I'm having is the wiring to hook a dynamically created button for example to an event handler requires reflection which is not supported in GWT. Is this conclusion correct? and if so, are there any other ways to achieve this type of dynamic UI using ExtGWT?

• Mac OS X, MySQL Preference Pane doesn't work

  - by Steve Kuo

  I downloaded and installed MySQL 5.1.47 for OS X 10.6 using the DMG archive: mysql-5.1.47-osx10.6-x86_64.dmg I also installed MySQL.prefPane and MySQLStartupItem.pkg. MySQL.prefPane is a Preference Pane. The problem is, whenever I attempt to start/stop MySQL from the Preference Pane, System Preferences just hangs. It runs at about 50% CPU forever, eventually I have for force quit System Preferences. The same thing happens if I toggle "Automatically Start MySQL Server on Startup". Basically the MySQL Preference Pane is not functional. Note that I have no problem starting MySQL from the command line: sudo /usr/local/mysql/bin/mysqld_safe I have tried reinstalling MySQL and the Preference Pane. I'm using the standard installation location, nothing out of the ordinary. Every time the MySQL Preference Pane just hangs. I'm doing this on a Macbook Pro (Intel) running OS X 10.6.3. There are no old versions of MySQL on this machine.

• How to create a Clob in JPA in an implementation agnostic way

  - by kazanaki

  Hello I am using Ejb3 and JPA (based on Hibernate and Oracle 10g at the moment) I have an entity that contains a clob @Entity @Table(name = "My_TAB") public class ExampleEntity implements java.io.Serializable { private Clob someText; public void setSomeText(Clob someText) { this.someText= someText; } @Column(name = "COLUMN_NAME") public Clob getSomeText() { return this.someText; } Then I want to save an entity of this type. At the moment I am doing the following which works perfectly ExampleEntity exampleEntity = new ExampleEntity(); exampleEntity.setSomeText(Hibernate.createClob(aStringValue)); someOtherDao.save(exampleEntity); However this ties my code to Hibernate! I have specifically avoided so far Hibernate extensions and used only JPA annotations. The code works because indeed Hibernate is my current implementation. Is there some sort of JPA API that allows me to create a clob in a generic way? So if later I decide to switch to Toplink/EclipseLink or something else I won't have to change a thing?

• Testing injected dependencies into your struts2 actions

  - by Barry

  Hi, I am wondering how others might have accomplished this. I found in the Spring documentation @required which I attempted to use in a 'test' but got this stmt INFO XmlConfigurationProvider:380 - Unable to verify action class [xxx] exists at initialization I have found another way in spring to do this is to write custom init methods and declare those on the bean but it almost seems like this is a strange thing to do to a struts2 action. In my application I inject through spring different web services (via setter injection) into different actions. I want to ensure on startup these are not null and set.

• Avoid implicit conversion from date to timestamp for selects with Oracle 11g using Hibernate

  - by sapporo

  I'm using Hibernate 3.2.1 criteria queries to select rows from an Oracle 11g database, filtering by a timestamp field. The field in question is of type java.util.Date in Java, and DATE in Oracle. It turns out that the field gets mapped to java.sql.Timestamp, and Oracle converts all rows to TIMESTAMP before comparing to the passed in value, bypassing the index and thereby ruining performance. One solution would be to use Hibernate's sqlRestriction() along with Oracle's TO_DATE function. That would fix performance, but requires rewriting the application code (lots of queries). So is there a more elegant solution? Since Hibernate already does type mapping, could it be configured to do the right thing?

• How to access MyProject.MySettings.Default.SomeSetting from xaml?

  - by Shimmy

  I have defined a StringCollection in the Project Settings. I want to use the values in a ComboBox. Is there a way to access it xamly? I tried: <CollectionViewSource Source="{x:Static src:MySettings.Default.MyCollection}" /> <CollectionViewSource x:Key="RoomSections" Source="{x:Static src:MySettings.Default.RoomSections}" /> *src is the xmlns of the project It says: "Type src:MySettings.Default was not found". The thing is that MySettings is a class that offers a Default property which is a thread-safe instance of MySettings, I really want to get the collection from the Default property and not by instantiating a new on. Is there other ways I am not aware of, maybe ObjectDataProvider can access static objects? I thought, maybe I can make in the App.xaml a global resource that return MySettings.Default which is an instance of the MySettings class, and then access all its properties, I will try that out, but I prefer the easy way.

• What is purpuse of T4 Generator in T4toolbox

  - by Fred Yang

  I am using T4toolbox, I am confused what the generator is for. I can run the following public class Generator1 : Generator { protected override void RunCore() { Template1 t = new Template1(); t.Output.File = "t3.txt"; t.Render(); } } or I can run t4 script directly like the following. Template1 t = new Template1(); t.Output.File = "t3.txt"; t.Render(); But I can do the same using t4 script without generator as well. So I mean can do the same thing with two approach "script -- generator -- template" and "script -- template", am I missing something? Thanks

• Best practice to display POI in iPhone's MapKit?

  - by iamj4de

  Assuming I have a database of POI with their respective coordinates (longitude & latitude). What would be the "standard" way to display the POI as annotations around the user's current location? To elaborate: Given a zoom level, I guess I have to search through the database for all POI whose distance to the current location < a certain threshold, then create annotations for them. Or is there any smarter way? If the user zooms in/out, moves the map... I will need to redo the whole thing again? It seems that MapKit has a mechanism to cache/reuse annotations. Should I create a lot of them right away and let MapKit decides what to render when the visible region changes? I guess this would make the transition smoother, but also consumes more memory. What is your experience with this? Thanks.

• Does the CLR store small values in 'natural' sized locations?

  - by izb

  In Java, a byte or short is stored in the JVM's 'natural' word length, i.e. for the most part, 32-bits. An exception would be an array of bytes, where each byte occupies a byte of memory. Does the CLR do the same thing? If it does do this, in what situations are there exceptions to this? E.g. How much memory does this occupy? struct MyStruct { short s1; short s2; }

• Killing a deadlocked Task in .NET 4 TPL

  - by Dan Bryant

  I'd like to start using the Task Parallel Library, as this is the recommended framework going forward for performing asynchronous operations. One thing I haven't been able to find is any means of forcible Abort, such as what Thread.Abort provides. My particular concern is that I schedule tasks running code that I don't wish to completely trust. In particular, I can't be sure this untrusted code won't deadlock and therefore I can't be certain if a Task I schedule using this code will ever complete. I want to stay away from true AppDomain isolation (due to the overhead and complexity of marshaling), but I also don't want to leave a Task thread hanging around, deadlocked. Is there a way to do this in TPL?

• Use python decorators on class methods and subclass methods

  - by AlexH

  Goal: Make it possible to decorate class methods. When a class method gets decorated, it gets stored in a dictionary so that other class methods can reference it by a string name. Motivation: I want to implement the equivalent of ASP.Net's WebMethods. I am building this on top of google app engine, but that does not affect the point of difficulty that I am having. How it Would look if it worked: class UsefulClass(WebmethodBaseClass): def someMethod(self, blah): print(blah) @webmethod def webby(self, blah): print(blah) # the implementation of this class could be completely different, it does not matter # the only important thing is having access to the web methods defined in sub classes class WebmethodBaseClass(): def post(self, methodName): webmethods[methodName]("kapow") ... a = UsefulClass() a.post("someMethod") # should error a.post("webby") # prints "kapow" There could be other ways to go about this. I am very open to suggestions

• Trying to INstall PHP on windows 7 ultimate with IIS6

  - by Jack

  I am trying to install php on my windows 7 machine. I have installed IIS 6.x and I have also installed php. I used this tutorial http://blogs.iis.net/bills/archive/2006/09/19/How-to-install-PHP-on-IIS7-_2800_RC1_2900_.aspx The only thing I didnt understand is this part: 4) Install IIS7, making sure you install the ISAPI Extension component (for PHP-ISAPI - which is what I use) or the CGI component (if you prefer CGI) during IIS installation (ISAPI and CGI are not installed by default) Now when i go to localhost I get an error. HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. 4: <handlers> 5: <add name="PHP" path="*.php" verb="*" modules="FastCgiModule" scriptProcessor="C:\web\php5\php-cgi.exe" resourceType="Unspecified" /> 6: </handlers> Also php pages do not work in IE, please help

• How to learn high-level Java web development concepts

  - by titaniumdecoy

  I have some experience writing web applications in Java for class projects. My first project used Servlets and my second, the Stripes framework. However, I feel that I am missing the greater picture of Java web development. I don't really understand the web.xml and context.xml files. I'm not sure what constitutes a Java EE application as opposed to a generic Java web application. I can't figure out how a bean is different from an ordinary Java class (POJO?) and how that differs from an Enterprise Java Bean (EJB). These are just the first few questions I could think of, but there are many more. What is a good way to learn how Java web applications function from the top down rather than simply how to develop an application with a specific framework? (Is there a book for this sort of thing?) Ultimately, I would like to understand Java web applications well enough to write my own framework.

• Problem creating ObjectContext from different project inside solution.

  - by Levelbit

  I have two projects in my Solution. One implements my business logic and has defined entity model of entity framework. When I want to work with classes defined within this project from another project I have some problems in runtime. Actually, the most concerning thing is why I can not instantiate my, so called, TicketEntities(ObjectContext) object from other projects? when I catch following exception: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. I found out it's brake at: public partial class TicketEntities : global::System.Data.Objects.ObjectContext { public TicketEntities() : base("name=TicketEntities", "TicketEntities") { this.OnContextCreated(); } with exception: Unable to load the specified metadata resource. Just to remind you everthing works fine from orginal project.
