• Program seems to get stuck ?

  - by Frank

  I have a Java program, I did some change and the strange thing is no matter what I do now, it will output the same result before my change, I looked into my system (Windows Vista), and clicked on "Generate a system health report", the result says : Symptom : A service is reported as having an unexpected error code Cause : One or more services has failed. The service did not stop gracefully, suggesting the service may have crashed or one of its components stopped in an unsupported way. Details : Service exited with code not equal to 0 or 1077 Resolution : Restart the service It doesn't say which service, and I defragmented my drives a few times, it still gave me the same report. I also checked my memory, it says no problem with ram. Everything else is ok, I re-started the windows a few times, got more free space on my C: drive, yet the Java program is still not responding to my new changes, unless I intentionally make a mistake, it gives me compile error, but if it can compile successfully, it still gives me the results before the change. What can I do to fix this ? Frank

• Seam-gen isn't working properly.. log4j acuses an error

  - by rgoytacaz

  Hello Seam Users, I'm having a couple problems with my Seam start up. I did the ./seam generate to reverse my current postgres db, which contains 4 tables, first I though everything was okay, just a warning message, but when I imported the project into eclipse, I saw that none of my packages had any class. This is the error that seam generate, got me. [hibernate] Executing Hibernate Tool with a JDBC Configuration (for reverse engineering) [hibernate] 1. task: hbm2java (Generates a set of .java files) [hibernate] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment). [hibernate] log4j:WARN Please initialize the log4j system properly. [javaformatter] Java formatting of 0 files completed. Skipped 0 file(s). Any ideas? The seam-gen was supposed to generate some entity classes, but its not. I suppose that error is causing the mis-behavior. Regards

• Is there a Tool for see files created with binary serialization?

  - by Néstor Sánchez A.

  I've working without problems serializating object graphs to and from files. Everything was fine until today: A dictionary, created in a constructor and NEVER deleted, was lost (null referece) just after deserialization from file, for the first time in more than a year doing the same without troubles. So, is there a Software Tool to look into binary serialization content showing a human/developer-readable version (a la Reflector) of what is stored? AKA: How to analyze (easy, no binary to IL translation. That would take months) binary serialized content? Thanks!

  - by Fraga

  i'm reading messages from MessageQueue using PeekCompleted, i do my process here and if everything go right, I need to remove it from the Queue! currenty i am using MyMessageQueue.Receive() and it works, but is this a reliable way of making sure each message will be processed right?

• iPhone: App crashes when I click on a cell in table view.

  - by Jack Griffiths

  Hi there, Compiling my application works—everything is fine. The only errors I get are by deprecated functions (setText). The only problem is now, is that when I tap on a cell in my table, the app crashes, even though it's meant to push to the next view in the stack. Any solutions are appreciated, if you need any code, just ask. Also, how can I only make sure that one cell goes to only one view? For example: When I tap on CSS, it takes me to a new table with different levels of CSS. WHen I tap on an item in that new view, it comes up with an article on what I just selected. Regards, Jack

• gvim "open in new window" should change directory to the one of the current file

  - by Flavius

  Hi I'm working in gvim with sessions and tabs, and everything works great. However there is something that is bothering me. Say I have two files open: /A/B/foo.ext and /C/D/E/bar.ext, the latter being opened last. Now say I want to open /A/B/foobar.ext. I have to go through the hassle of navigating upwards to / and from there to /A/B. I would like to simply change my active tab to /A/B/foo.ext and have gvim automatically change its active directory to /A/B/, so that when I want to open /A/B/foobar.ext with /A/B/foo.ext being active, I'm already in the right CWD. This would be very time-saving if you work with two different projects at a time and need to switch back and forth between the two. Is there any such script that does just that? Thanks.

• WPF with code only

  - by rwallace

  I've seen a lot of questions about the merits of WPF here, and essentially every answer says it's the bee's knees, but essentially every answer also talks about things like XAML, in many cases graphic designers and Expression Blend etc. My question is, is it worth getting into WPF if you're a solo coder working in C# only? Specifically, I don't have a graphic designer, nor any great talent in that area myself; I don't use point-and-click tools; I write everything in C#, not XML. Winforms works fine in those conditions. Is the same true of WPF, or does it turn out that important functions can only be done in XAML, the default settings aren't intended for actual use and you have to have a graphic designer on the team to make things look good, etc., and somebody in my position would be better off to stick to Winforms?

• Symfony 1.4: Is it possible to prevent escaping of a redirect URL?

  - by Tom

  Hi, If I do a redirect in action as normal: $this->redirect('@mypage?apple=1&banana=2&orange=3'); ... Symfony produces the correct URL: /something/something?apple=1&banana=2&orange=3 However, the following gets escaped for some bizarre reason: $string = 'apple=1&banana=2&orange=3'; $this->redirect('@mypage?'.$string); ... and the following URL is produced: /something/something?apple=1&amp;banana=2&amp;orange=3 Is there a way to avoid this escaping and have the ampersands appear correctly in the URL? I've tried everything I can think of and it's driving me mad. I need this for a situation where I'm pulling a saved query as a string from the database and would just like to latch it onto the URL. I'm aware that I could generate an array from the string and then generate a brand new URL from the array, but it just seems like a lot of overhead because of this silly escaping. Thanks.

• Undetermined type conversion in VB.NET 2008

  - by user337501

  I figured this would be a quick google, but extensive searching hasnt yielded any results. Everything about type conversion seems to dance around this concept. I want to get the type of variable "a", and make a new variable named "b" of that type. Otherwise I could have "a" as a type already declared and "b" simply as an Object, then try to cast "b" to the type of "a". Dim a As Integer Dim b As Whatever a Is OR TryCast(b, Whatever a Is) I would also like to make the conversion using a variable representation of the type, but cant find info on how to do that either. Sorta like: Dim a As Integer Dim b As Object Dim t As Type t = a.GetType() TryCast(b, t) Realizing I'm completely misusing TryCast here, I'm mostly trying to get my goal across. I figured it would be an easy quick thing to do but I cant really find any specific info on it. Any ideas?

• Is there a "vim runtime log"?

  - by Somebody still uses you MS-DOS

  Sometimes I try a customization/command in my vimrc. Everything seens to be correct, but it just doesn't work. It's difficult to know what's happening when vim starts, and know which command failed or not, so it's really difficult to debug what can be causing a problem in my vimrc. It's a trial-error approach, which is time consuming and really a PITA. For example, I'm having problems with snipmate plugin in some files and just don't have a clue on how to discover the problem. Is there a "runtime log" when vim starts, telling which commands it executed, which ones failed and such? This would help me a lot.

• My AES encryption/decryption functions don't work with random ivecs

  - by Brendan Long

  I was bored and wrote a wrapper around openSSL to do AES encryption with less work. If I do it like this: http://pastebin.com/V1eqz4jp (ivec = 0) Everything works fine, but the default ivec is all 0's, which has some security problems. Since I'm passing the data back as a string anyway, I figured, why not generate a random ivec and stick it to the front, the take it back off when I decrypt the string? For some reason it doesn't work though. With random ivec: http://pastebin.com/MkDBFcn6 Well actually, it almost works. It seems to decrypt the middle of the string, but not the beginning or end: String is: 0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF Encrypting.. ???l%%1u???B! ?????`pN)?????[l????{?Q???2?/?H??y"?=Z?Cu????l%%1u???B!

Maybe some stupid mistake, or maybe I'm missing something about AES?

• .NET --- Textbox control - wait till user is done typing

  - by Cj Anderson

  Greetings all, Is there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occurs on the textchanged event and everything works perfectly. However, I noticed that there is a bit of lag of course because if a user is quickly typing into the textbox the program is busy doing a query for each character. So what I was hoping for was a way to see if the user has finished typing. So if they type "a" and stop then an event fires. However, if they type "all the way" the event fires after the y keyup. I have some ideas floating around my head but I'm sure they aren't the most efficient. Like measuring the time since the last textchange event and if it was than a certain value then it would proceed to run the rest of my procedures. let me know what you think. Language: VB.NET Framework: .Net 2.0 --Edited to clarify "done typing"

• How many address fields would you use for a UK database?

  - by Draemon

  Address records are probably used in most database, but I've seen a number of slightly different sets of fields used to store them. The number of fields seems to vary from 3-7, and sometimes all fields are simple labelled address1..addressN, other times given specific meaning (town, city, etc). This is UK specific, though I'm open to comments about the rest of the world too. Here you need the first line of the address (actually just the number) and the post code to identify the address - everything else is mostly an added bonus. I'm currently favouring: Address 1 Address 2 Address 3 Town County Post Code We could add Country if we ever needed it (unlikely). What do you think? Is this too little, too much?

• Retrieve baseUri w/o resorting to Application.Current

  - by beaudetious

  My custom controls are not loading in VS.NET's designer because of a null reference exception. It's got everything to do with the way I am retrieving the baseUri of the application when it runs in the browser: _uriPrefix = Application.Current.Host.Source.AbsoluteUri.Substring(0, Application.Current.Host.Source.AbsoluteUri.IndexOf("/ClientBin")).Trim(); According to the exception details and the help file I'm directed to (here) I'm not correctly designing my app for a runtime that's not the browser (i.e. the new WPF editor in VS.NET or Expression Blend). So, the question is how do retrieve the baseUri (the http://localhost:#### part of my application) if I can't use Application.Host which apparently is null during design time? is there a safe way to do this so I can load my custom controls in a designer?

• How does one advance in programming?

  - by Joe Barr

  I really have the felling as if I'm stuck in my own craft. I've been developing and learning for a while now and keep having the feeling that I should advance more, or even be more knowledgeable. I've started projects I didn't finish because I thought I lacked the knowledge and the skill to make that feature work just right, or to make that code magically appear on my screen. I've read books I didn't finish, thinking I wasn't advanced enough for the subjects they covered. I've been around long enough to know that everything comes with experience, hard work and dedication. Having said this, I just want to be able to work without getting stuck on a particular problem that involves my cluelessness of a language or a tool feature. My question to you would be, how does one advance in programming? What are the secrets (if any) to advance to the point of fluency in a particular language or a task. Thank you!

• Is there a tool to build and test a local change on multiple platforms

  - by Ben

  A company I used to work for was plagued with build breakages. So they made a tool that would zip up a developers local changes (which it detected from SCM) and send them to a remote server for a test build. The remote server would update its copy of the source with the repository and then apply the changes it received from the developer. It would then build and test the changes. We actually targeted multiple platforms so it would do the above for each of those platforms. When it was done, if everything was green, the developer was reasonable confident they could submit the change without breaking the "real" build. Are there any tools out there that do something similar?

• Mirror a website with httrack while executing javascript

  - by Martin

  I want do save a mirror of www.youtube.com/tv. I obviously do not want to save the videos. I want the code running the website in a local copy, everything else can stay remote. The code I want is mainly contained in 2 files: live.js and app-prod.js. I tried using httrack. I have issue parsing the javascript to load anything past the first file: live.js. The %P parameter does not help. httrack www.youtube.com/tv +* -r6 --mirror -%P -j It doesn't go further than live.js because some javascript needs to be executed to load the next file. I know I can do this manually with any browser. I want to automate the process. Is httrack able to do this by itself? If yes, how?

• Transferring Data Between Server and Client (Mobile)

  - by Byron

  Scenario: Client (Mobile) - .Net CF 2.0, SQL CE 3.0 Server - .Net 2.0, SQL Server 2005, Web Service Client and Server database schemas differ. From server - only certain columns from certain tables need to be synced. From client - everything will need to be synced once client has made changes. Client will continually poll a web service to download and upload data. A framework will be developed to package and unpackage data, used by both client and server. How would you develop the packaging and unpackaging? Use datasets, serialise strongly typed objects? All suggestions welcome. Thanks

• ObjectDataSource cannot find type when deployed to SharePoint

  I'm receiving the following error when deploying a feature containing ASP.NET pages to our development SharePoint servers: System.InvalidOperationException: The type specified in the TypeName property of ObjectDataSource 'odsYears' could not be found. Our .dll is being deployed to the GAC and our pages are being deployed to the the respective Features directory in the 12 hive. We are not receiving this error on our Sandbox SharePoint server. I disassembled the .dll to be sure the class was being deployed and everything looked ok. Does anyone have any ideas on why this would not work on one of our SharePoint environments? Thanks.

• Will Django user permissions work for models with inline tabular forms of other models?

  - by stinkypyper

  I am setting up DJango admin to make a model editable. On the same page I have tabular inline of a child model. Everything works as expected. Now I want to restrict permission on the tabular inline child form. Specifically remove update and delete permissions on it. I have tried removing the permissions for the admin user using the 'user permissions' of that user. However, it does not work. Does DJango respect the user permissions in regards to inline model forms?

• Is Pex (Test generation) really usefull tool?

  - by Yauheni Sivukha

  Yes, it is possible to generate tests on boundary values for functions like "Sum" or "Divide". Pex is a good tool here. But more often we create tests on business behaviour. Let's consider example from classic Beck's tdd book: [Test] public void ShouldRoundOnCreation() { Money money = new Money(20.678); Assert.AreEqual(20.68,money.Amount); Assert.AreEqual(2068,money.Cents); } Can this test be generated? No :) 95 % of tests in my projects check business logic, and can not be generated. Pex (Especially in pair with Moles) can give 100% code coverage, but a high code coverage rate of a test suite does never indicate, that code is well tested - It only gives false confidence that everything is tested. And this is very dangerous. So, the question is - Is Pex really usefull tool?
