• VS 2008 SP1 text editor flickering over remote desktop connection

  - by AltairDusk

  I am connecting from a Windows 7 x64 machine to my dev machine running Windows XP SP3 using the built in remote desktop client. For most apps it works fine with no problems, for Visual Studio whenever I am typing the entire text editor keeps redrawing. I stumbled across this question: http://stackoverflow.com/questions/873849/vs-2008-sp1-over-remote-desktop-constant-repainting and I have tried all of the suggestions in it to no effect, including resetting all VS settings back to default then disabling the suggested settings. Has anyone found a reliable solution to this? I feel like I'm going insane with the screen constantly refreshing when I'm working from home. Some additional information: Remote Desktop is set to run at 1680x1050, 15bit color, Low-speed broadband for the experience setting with all but Visual styles and Persistent bitmap caching unchecked. Visual Studio 2008 Team System is running on the dev machine with Service Pack 1 and Power Commands installed.

• UI Terminology: Logon vs Login

  - by Brad Leach

  I am crafting an application and cannot decide whether to use the terms Login/out or Logon/off. Is there a more correct option between these two? Should I use something else entirely (like "Sign on/off"). In terms of usability, as long as I am consistent it probably doesn't matter which terms I choose, but I did wonder about the origins of the terms - and whether one or another makes more grammatical sense. I also care deeply about the application I am creating, and want to take the time to investigate all aspects of its user experience.

• mod_php / mod_suphp / FastCGI | Which do you recommend and why.

  - by Saif Bechan

  I am at the point that I have to choose on what type of setup my application should run. I know there are some types available where apache runs smooth on, but they all have there downsides. System: Apache 2 / PHP 5.2 I hope you can give me some tips from firsthand experience. To give you an example of what to be covered. - Performance - Ease of setup - Security I know this does not really involve programming, but I have seen post concerning this and I know that you guys/girls here are certainly qualified to comment on this subject.

• Is there a HIPAA certification that would be helpful to programmers?

  - by Aequitarum Custos

  I work at a Medical Billing company that's software handles many facets of the centers practice, including patients, treatments, etc. To be frank, the only thing I know about HIPAA is security is paramount. I was wondering if there were any training courses with an earned certification proving knowledge/experience that I could use to increase my worth to the company, and give them a selling point (we have HIPAA certified employees). I did a Google search and found this site, but it does not appear legitimate, and I'm trying to avoid any of those fake certification/degree sites. Does anyone know of any recognized and legitimate (preferably government sponsored) HIPAA certifications useful to programmers? If state is a factor, I live in Oklahoma.

• How to start recognizing design patterns as you are programming?

  - by Jon Erickson

  I have general academic knowledge of the various design patterns that are discussed in GoF and Head First Design Patterns, but I have a difficult time applying them to the code that I am writing. A goal for me this year is to be able to recognize design patterns that are emerging from the code that I write. Obviously this comes with experience (I have about 2 years in the field), but my question is how can I jumpstart my ability to recognize design patterns as I am coding, maybe a suggestion as to what patterns are easiest to start applying in client-server applications (in my case mainly c# webforms with ms sql db's, but this could definitely be language agnostic).

• Subsonic custom mapping of objects to tables

  - by codekaizen

  Geeting, I'm using Compact Framework 3.5 and have tenatively settled on a custom build of Subsonic 3.0 to do data access. The trouble is that I am used to developing model-first but am also interested in keeping control of my DB schema. Therefore, neither ActiveRecord or Repository appears to meet my needs, and I want to use my existing POCO model and map it to my existing tables. I'm used to doing this via NHibernate and Entity Framework. After some investigation, it appears that I might be able to author a custom QueryMapping to give me the custom mapping I want. Before I start down this path, however, I'd like to see some kind of example of this being done. I can't seem to find any on the web, and wonder if anyone could give input on experience with Subsonic, model-first and a custom Table-per-Type and Table-per-Hierarchy mapping.

• Stuck at "Hello World" with IntelliJ IDEA 9.0.1 for Scala

  - by Alex R

  I've been using Eclipse since 2.x and and IDEs in general for over 20 years (since Turbo Pascal and Turbo C in the late '80s!). (that preamble is supposed to imply, "I'm not an idiot" ... LOL :-] ) I'm trying to use the debugger in IntelliJ 9.0.1. I've resigned myself to an old standby: class hello { def main(a: Array[String]) = println("got args: " + a) } Alas, I'm unable to get even this simple Scala example to run. I'd like to eventually put a breakpoint in it, but for now just running it would be great. I have Java 1.6u20 and the Scala plug-in 0.3.473 (January 2010). The error below summarizes my experience: What possibly could I be doing wrong? Thanks

• Is there a way to watch all COM activity on a computer?

  - by Fake Name

  I'm trying to deal with a piece of specialized hardware, that presents it's interface as a COM object, using win32com in Python. However, the documentation for how to actually set up the hardware through the COM object is sparse (it requires a significant amount of initialization), and entirely oriented at using a bunch of pre-built libraries for Visual Studio, which are not accessible through python. That said, is there any way to watch all local COM activity, so I can sort through the activity logs to try and figure out how the existing demo programs properly initialize the hardware, and replicate the behavior in my python script? Ideally, there would be something in the vein of wireshark for doing this. Note: I have very little (read: basically no) experience using COM, as my focus is mostly embedded hardware (and a little python dev on the side). However, I'm stuck with this particular device.

• Native (non-jqueryui) way to set prompt() input field inline.

  - by Anthony

  I might just be using the wrong keywords on Google, but what I have in mind is: -------------------------------- | What is your mailbox? | | | | [ ]@mail.example.org | | | | [OK] [Cancel] | -------------------------------- The idea being that the input field is followed right behind by the mail server name, to help avoid instances where: If I don't make it follow right behind, the user puts in the whole thing, If I default it to "[email protected]" they delete the server name. In either case, it's not too big a deal, as I will know that if the returned value does have the server, to remove it and if doesn't, I know what server it belongs to, but I think this visual aid will be a better user experience and lower the amount of validation worries I tend to get.

• Selling an app to a company - How much to charge?

  - by Moshe

  I wrote an app targeting a particular clientele. A software company with a reputation among my target audience is willing to negotiate a price to either license or buy it. As a newcomer to the app store, I am not sure that I will successfully market it myself. What would be appropriate terms of a sale or license and what about pricing? I am looking for answers that draw from personal experience with software, although not necessarily apps. I've seen this post on SO, but it's a few years old and I assume that the app market has changed and stabilized somewhat. Thanks.

• How do I tweet, using the DotNetOpenAuth library?

  - by MedicineMan

  I just downloaded the DotNetOpenAuth library and ran the AuthConsumer demo. It is an excellent library so far! Everything worked as advertised, which has not been my experience with a lot of Facebook and Twitter sample code that I have been working with recently. What I am trying to figure out is: How do I tweet using this library? I am currently planning to implement this in ASP MVC, but my initial thoughts is that the presentation platform doesn't matter all that much at the level I'm looking at.

• Creating an installer with WPF forms, packaged files and custom setup actions

  - by RodH257

  I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

• How to prepare for a Java test?

  - by Zenzen

  Ok so in two days I have a test for my dream job (well it's an internship, but still!) and for quite some time now I've been reading the SCJP Guide book in order to prepare myself. BUT seeing how slow my reading speed is I guess finding a website with some "java essentials" or "standard java test questions" and going through it in those 2 days would be a better idea. Don't misunderstand me, I do have java experience and it's "only" an internship, but we all know how programming tests look like and how tricky they can be. So are there any online resources you could recommend me? I know 2 days is not much, but well I was informed bout the test 1-2days ago.

• The speed of .NET in numerical computing

  - by Yin Zhu

  In my experience, .net is 2 to 3 times slower than native code. (I implemented L-BFGS for multivariate optimization). I have traced the ads on stackoverflow to http://www.centerspace.net/products/ the speed is really amazing, the speed is close to native code. How can they do that? They said that: Q. Is NMath "pure" .NET? A. The answer depends somewhat on your definition of "pure .NET". NMath is written in C#, plus a small Managed C++ layer. For better performance of basic linear algebra operations, however, NMath does rely on the native Intel Math Kernel Library (included with NMath). But there are no COM components, no DLLs--just .NET assemblies. Also, all memory allocated in the Managed C++ layer and used by native code is allocated from the managed heap. Can someone explain more to me? Thanks!

• How to package .Net framework in Visual Studio project?

  - by raj.tiwari

  I have created a C#/.Net application using visual studio. I have also created an installer project that puts out two files: An MSI file Setup.exe file In my installer project properties I have setup .Net 3.5 as a prerequisite. What I would like my installer to do as as follows: Put out a single file (MSI/exe/whatever) that also includes .Net framework prerequisite The installer should check whether .Net framework is installed on the target machine. If not, it should install it from its own bundled copy. Right now my installer sends people to the web for getting .Net. This is not the user experience I want. Thanks for your help. -Raj

• Best XML Based Database

  - by monmonja

  I had been assigned to develop a system on where we would get a XML from multiple sources (millions of xml) and put them in some database like and judging from the xml i would receive, there wont be any concrete structure even if they are from the same source. With this reason i think i cannot suggest RDMS and currently looking at NoSQL databases. We need a system that could do CRUD and is fast on Read. I had been looking at MarkLogic and eXist, which are both XML based NoSQL databases, have anyone had experience with them? and any other suggestion? Thanks

• Any good Open Source or Cheap ASP.NET Catalog Applications

  - by Zhaph - Ben Duguid

  We're looking for a cheap-to-free "off the shelf" ASP.NET catalogue application, that will meet the following requirements: Support two kinds of listings: Suppliers of Services Suppliers of Products, and their Products Suppliers can be categorised by: Area of specialisation - including sub-categories Location Other data, e.g. where listing came from Versioning of supplier/product details Easy to use management interface Use masterpages so we can drop it into our existing site layout Run on a Windows 2003 server, with .NET 3.5 installed In an ideal world, the following additional requirements might be met: Suppliers can manage their own listings Other products that are available to us (that will obviously need some additional development to meet these requirements) are: Content Management System (MS) Commerce Server - bear in mind we're not selling the products/suppliers, just listing them Simple DB application. I'm happy to knock something up in MCMS/simple DB, I'm just looking to see if anyone's had any experience with off the shelf apps that could save us some time. I'm also happy to receive "Don't use this because" type answers. Thanks.

• Which C# / .NET free or standard bits and pieces do I need to make a simple Windows desktop app back

  - by jjujuma

  I'm coming from a Java / web background with no C# experience and I want to write a prototype C# / .NET desktop app to run against my existing DB2 database. The idea is that the prototype should use libraries and tools which are suitable for scaling up to full production and should be standard and free. Of the top of my head, the two biggest things I need are: an IDE a GUI toolkit / set of components a JDBC equivalent and/or possibly a full blown ORM system What are my options? Note I don't mind paying for full blown Visual Studio in the long run, but for now everything needs to be free, including the IDE.

• Creating an iphone book application

  - by ennuikiller

  I have some experience creating iphone applications and would now like to create an iphone book application. Browsing the Book category in iTunes it seems to there is a standard format for building these apps, however, googling for how to build an iphone book app produces no useful results. This type of application is also not addressed in any of the iphone development books I've seen. Is there a standard method fot building these book applications? Or is it simply copying the text is some format (pdf, txt, html?) and then writing a document handling api? It seems there already must exist apis for doing this. Can anyone point me in the right direction. Thanks in advance!

• VB.net, disable proxy for entire program

  - by Brent

  Ever since upgrading to Visual Studio 2010, I'm running into an issue where the first web request of any type (WebRequest, WebClient, etc.) hangs for about 20 seconds before completing. Subsequent calls work quickly. I've narrowed down the problem to a proxy issue. If I manually disable proxy settings, I don't experience this delay: Dim wrq As WebRequest = WebRequest.Create(Url) wrq.Proxy = Nothing What's strange is that there are no proxy settings enabled on this machine in Internet Options. What I'm wondering is if there is a way to disable proxy settings for my entire project in one shot without explicitly disabling as above for every web object. The main reason I want to be able to do this is that I'm trying to use an API (http://code.google.com/p/google-api-for-dotnet/) which uses web requests, but does not provide any way to manually disable proxy settings. Can anyone point me in the right direction? Thanks!

• Where to start with freelance Programming?

  - by hhafez

  Hi I would like to do start freelance Software Development but I don't know where to start... The main problem I have is that I live in Melbourne, Australia while most freelance programming websites are in the US. Have you had experience freelancing? How did you get started? Are there any legal procedures you need to perform before you get started (for example for tax purposes)? Do you need to have your own business name? Does it really matter if you live in the same city/country as your client? Thanks

• Simple VM That allows booting from folder or disk

  - by None

  I was wondering if there was a very simple and free virtual machine that would allow you to boot from a folder or disk image that couldn't damage my hard disk. I am using a MacBook and am looking into operating system programming. I found a tutorial on the internet that looked promising (http://www.viralpatel.net/taj/tutorial/hello_world_bootloader.php). I want to try this but using a VM instead of actually booting from a disk. If I made a folder or disk image containing the boot.bin file and wanted to try the OS I made (while booting from a folder or disk image, not a disk), is there a VM that would let me do it? I have no previous experience with virtual machines. I also want to be sure my hard disk would not be damaged.

• Steaming a non-PCM WAV file to a SilverLight application

  - by Satumba

  Hi, I would like to allow users to play recorded WAV files that stored on a server back to a Silverlight application as a client to play them. I saw that there is a way to play a WAV file on Silverlight (here), but when i tried to impliment it, i got an error playing the file because it is not in PCM format but encoded. The files that i'm trying to play are encoded with a special encoder, so i thought that the only way is to decode the WAV file on the server and stream it back to the client. The limitation is that the decode process should occur in real time because it is not reasonable to convert all the WAV files that exists. Is it possible to do it? Which streamer can i use? (Windows Media Service can help here?) Does somebody has any experience with such a scenario? Appreciate your help.

• C Differences on windows and Unix OS

  - by zapping

  Is there any difference in C that is written in Windows and Unix. I teach C as well as C++ but some of my students have come back saying some of the sample programs does not run for them in Unix. Unix is alien for me. Unfortunately no experience with it whatsoever. All i know is to spell it. If there are any differences then i should be advising our department to invest on systems for Unix as currently there are no Unix systems in our lab. I do not want my students to feel that they have been denied or kept aloof from something.

• AS3: How to access pixel data efficiently?

  - by JonoRR

  I'm working a game. The game requires entities to analyse an image and head towards pixels with specific properties (high red channel, etc.) I've looked into Pixel Bender, but this only seems useful for writing new colors to the image. At the moment, even at a low resolution (200x200) just one entity scanning the image slows to 1-2 Frames/second. I'm embedding the image and instance it as a Bitmap as a child of the stage. The 1-2 FPS situation is using BitmapData.getPixel() (on each pixel) with a distance calculation beforehand. I'm wondering if there's any way I can do this more efficiently... My first thought was some sort of spatial partioning coupled with splitting the image up into many smaller pieces. I also feel like Pixel Bender should be able to help somehow, however I've had little experience with it. Cheers for any help. Jonathan
