  • Where should I put interface?

    - by Roman
    I program a class in which I have a method which takes an callback object from an external software. At the moment Eclipse says that it does not know the type of the object I gave as argument (it is expectable since I do not specify this type, it's done by the external software). So, I think I need to write an interface for the object which I give as an argument to my method. In this respect I have two questions. Is it really so? Can I solve the mentioned problem in the mentioned way. If it is the case, where should I put this interface? In the same file where my class is? In the class? Outside of the class?

  • Automatic images translation to 3d model

    - by farrakhov-bulat
    I'm quite interested in automatic images translation to 3d models. Not really for commercial product, but from the point of possible academic research and implementation. What I'd like to achieve is almost transparent for user process of transformation series of images (fewer is better) to 3d model which might be shown in flash/silverlight/javafx or similar. Consider online furniture store with 3d models of all items in stock. Kinda cool to have ability to see the product in 3d before purchasing it. I managed to find a few pieces of software, like insight3d, but it couldn't be used in my case I guess. So, are there any similar projects or tips for me? If it would require to write that piece of software - I'd really love to dig into research on this field.

  • Change a registry value in vb.net

    - by mhofer
    Hello, I have searched a lot to find a solution for my problem, but I can't find any specific solution. I need to change a value which is stored under HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME. It is not possible to use .NET's registry functions, since they have drastic restrictions. The following snippet should solve my problem: Dim regKey As RegistryKey Dim ver As Decimal regKey = My.Computer.Registry.LocalMachine.OpenSubKey("HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME", True) regKey.SetValue("IP", "192.168.10.15:18500") regKey.Close() Unfortunately, I get a NullReferenceExeption when I try to set the value. What should I do? I have imported Microsoft.Win32 and RegistryKey doesn't accept any constructor... cheers mike

  • What are the core mathematical concepts a good developer should know?

    - by Jose B.
    Since Graduating from a very small school in 2006 with a badly shaped & outdated program (I'm a foreigner & didn't know any better school at the time) I've come to realize that I missed a lot of basic concepts from a mathematical & software perspective that are mostly the foundations of other higher concepts. I.e. I tried to listen/watch the open courseware from MIT on Introduction to Algorithms but quickly realized I was missing several mathematical concepts to better understand the course. So what are the core mathematical concepts a good software engineer should know? And what are the possible books/sites you will recommend me?

  • Threaded application sleeps with other application

    - by DeeD
    I have a weird problem with my threaded software. I start 2 instances of the software. Each instance has 2 threads, one thread creates a socket to use, and the other one is uses the socket for communication. When one of the threads in one instance calls sleep(3), the other threads in the the other instance sleeps too. And the weirdest thing is that when I rebooted the computer, it works the first time, but after trying a second time, it sleeps like described. How is this possible? Is it using some shared resource?

  • Crash when checking BOF property of pessimistic locked ADO recordset

    - by Patrick
    Bit of an odd one for you: I've got two connections to a database, on one I've opened a _RecordsetPtr with a pessimistic lock. I can no longer send an UPDATE command on the other connection. I can send a SELECT command on the second connection and data is returned. If I use a read only lock then there are no problems however when I use a pessimistic lock on the second connection as well I can check the State == adStateOpen but the program hangs when I test the BOF property! If I don't test the BOF property and try to call moveNext on the second connection the software hangs If I do neither of these I am able to access the data via the second connection but trying to access the data from the first connection causes the software to hang. Any one seen anything similar as I'm a bit stuck? EDIT : it wasn't hanging, someone had put a 30 minute timeout on the connection and I wasn't waiting that long while testing...

  • Hosting my own SVN repositories

    - by TheAdamGaskins
    I've been experimenting with Google Code and Sourceforge and the like, and am happy with what I've found. The main problem with them, is that you have to have your project be open source to use them, so anybody can edit them. So... is there some way I can have my own svn repositories on my own server? I have FTP access, cpanel, and all that. If it helps any: Operating system Linux cPanel Version 11.26.20 Architecture x86_64 MySQL version 5.0.91-community-log Apache version 2.2.13 PHP version 5.2.11 cPanel Pro 1.0 (RC1)

  • Web API Presentation at DC DNUG

    - by Steve Michelotti
    This Tuesday (July 19), I’ll be presenting the ASP.NET Web API at the DC DotNet Users Group. Abstract: Modern web applications have seen an explosion in Web API creation. Twitter, Facebook, Google, Azure, you name it – it is becoming essential to provide a Web API so that consumers can build applications and mashups on top of your services. Web 2.0 has shown a trend away from SOAP towards a REST architecture style. With the new ASP.NET Web API, Microsoft is now providing first-class support for HTTP services including tools to apply the richness of a REST architectural style. This demo heavy presentation will show how the new ASP.NET Web API will enable you to build rich HTTP services in a REST architectural style while leveraging custom media types, custom HTTP handlers, jQuery and more! The presentation will also cover new features of MVC 4 including Razor enhancements, Web Optimizations, and more.

  • Ubuntu display - no existent

    - by Patrick M
    My HP Pavillion Dv5 1004nr worked great with Ubuntu up until 11.04. Now, ever since Unity desktop environment the display has been sporadic at best. I was told that the video driver bugs (known and largely ignored) were fixed for the ATI raedon card in my laptop with 13.04. So I installed it. 13.04 doesn't even detect the display. Boots to black screen every time now. Is there ever going to be a fix for the AMD architecture with ATI raedon chipsets? do the developers even care? this has been an issue for years, and no sign of a fix in sight....

  • Communication between .net winform and webform

    - by Pablo
    Hi, I need to make a webform communicate with a winform and back to the webform. The reason for this is it exists a webform software already made, and now it's needed the behavior of a .net component only available for winforms. We've tried going with Process.Start and shell.execute but with this approach the software hangs or it takes too long to respond. The webform also needs to be called from client pcs in the network, I think this adds another problem due to the non possibility of calling the execution of a file from a webform remotelly, but I dont know much about this technical issue we've read some articles about embedding a winform in a webform, sending data from a winform to a webform, etc. and we would like to know what's the recommend approach (if there is any) for handdling a situation like this.

  • New eBook: In-Memory Data Grids for Dummies

    - by jeckels
    We've just released a new eBook In-Memory Data Grids for Dummies. This is a fantastic resource if you're looking to explain in-memory data grids to colleagues, convince your boss of their value, or even discover some new use cases for your existing investment. In true "Dummies" style, this eBook will walk you through the basics tenets of in-memory data grids, their common use cases, where IMDGs sit in your architecture, and some key considerations when looking to implement them. While the title may say "Dummies," we know you'll find some useful overview and technical information in the resource. It's published by us on the Coherence team in partnership with Wiley (the "Dummies" company), but it's not only about Coherence or Oracle. In fact, we took pains to make this book fairly neutral to give you the best information, not a product pitch. Happy reading! Download the eBook now

  • Windows 8 sera adapté aux puces ARM, Microsoft fait la première démonstration officielle de l'OS au CES de Las Vegas

    Windows 8 sera adapté aux puces ARM Microsoft fait la première démonstration officielle de l'OS au CES de Las Vegas Mise à jour du 06/01/2011 par Idelways Après plus d'un an de spéculations et de fuites involontaires (ou pas), Steve Ballmer vient de faire la première démonstration du successeur de Windows 7, et a annoncé que l'OS supportera en natif les puces ARM. On sait donc désormais que Windows 8 (bien que Ballmer ait fait très attention d'éviter de lui donner le moindre nom) fonctionnera sur une architecture System-on-a-chip (SoC), fournie dans un premier temps par NVIDIA et Texas Instruments. Le PDG ...

  • 32/64 Bit Question

    - by user48408
    Here's my question. What is the best way to determine what bit architecture your app is running on? What I am looking to do: On a 64 bit server I want my app to read 64 bit datasources (stored in reg key Software\Wow6432Node\ODBC\ODBC.INI\ODBC Data Sources) and if its 32 bit I want to read 32 bit datasources, (i.e. Read from Software\ODBC\ODBC.INI\ODBC Data Sources). I might be missing the point, but I don't want to care what mode my app is running in. I simply want to know if the OS is 32 or 64 bit. [System.Environment.OSVersion.Platform doesn't seem to be cutting it for me. Its returning Win32NT on my local xp machine and on a win2k8 64 bit server (even when all my projects are set to target 'any cpu')]

  • Architects into videogames

    - by Ángel
    I'm an architecture student in my last year. I've always been interested in videogames design. I use 3d Max and Photoshop on a daily basis, and I was thinking about aiming for a career in videogames, starting as a level/environment designer. How should approach it? Is it worthy to spend some time learning UDK or CryEngine? Should I try a smaller but more general software? I know some programming already. Finally, will my skills as an architect be something valuable in the indusrty? Thanks in advance.

  • soft stoppped working

    - by Jack Morton
    this is might be really weird, but I have no idea what kinda wizardry of this. Basically, my Visual Studio stopped responding to my changes, it stopped building solution. I can comment code, which would completely ruin the logic of program, and Visual Studio will still run program that I guess it has in memory. It's really annoying, and I have no idea what it is. I keep restarting software, but it's still does the same. It's a licensed software. I was wondering If someone knew what was going on. Thanks!

  • Get the selected file in an Explorer window

    - by Jon Fournier
    I'd like to know how, if possible, to get the path of the selected file in an open Windows Explorer window. If not, would it at least be possible to get the folder path of an open Windows Explorer window? The end reason I'm doing this, is a software tool I'm writing requires a user to select a file. I figure if they're already moving the file around with Windows Explorer and then start my tool up, it'd be good not to have to make them navigate to the folder again in the file open dialog box. My software would then be able to identify if it's got the right file extension and if so, just ask the user if they want to import that file. Thanks.

  • C#: protecting trial releases

    - by anfono
    I want to provide a trial version of my software. This version should only be evaluated within a specific period of time. Let's say only during January 2011. As this software massively uses the system clock in processing, it would be quite annoying to set the clock to an earlier time to be able to use it over and over. So because of this, I wound't think of a more complicated protection mechanism. So I have thought about exiting after a test like: if (DateTime.Now.Year != 2011 && DateTime.Now.Month != 1) { MessageBox.Show("expired!"); Application.Exit(); } How easy will this be cracked :-) ? Is there a "safe" way to do this ?
