  • Django: How to handle imports in a reusable app

    - by facha
    everyone I'm just starting with django. It is not quite clear to me, how should I write an app I could reuse later. In every tutorial I read I see the same piece of code: view.py from project.app.models import MyModel So, if I move my apps to another project, I'll have to modify the "project.app.models" so that it looks like "project2.app.models" for every app I move. Is there a way to avoid that? Thanks in advance.

  • Tools to convert XML to HTML using XSLT

    - by armannvg
    I'm beginning to work on a project which has some extensive XML XSLT processing to render output HTML. Some changes need to be made to the XSLT and I need some tool that can help me modify it without having to run the solution every time. Something that can help me visualize the changes I'm making to the rendered HTML. I've found StylusStudio but I preferably would want a freeware that I could use

It looks like the issue is due to the following line not working properly: builtin eval export $previousFilenameVar=$filename I have a some theories to explain why: in the original code, functions are declared and exported as readonly which makes them unable to modify global variable. I removed readonly declarations in the above sample, but probleme persists. Function calls are performed in $() which should make them run into seperated shell instances so variable modified are not exported to the main shell But I cannot manage to find a workaround to this issue... Any help is appreciated, thanks in advance!

  • Adding fields to user registration in Mediawiki

    - by boogie
    Hi, I've been Googling a lot, but I just can't figure out how to add a couple fields to user registration. By default Mediawiki only asks for username, password and real name. I noticed that form is a template under /includes/templates/UserLogin.php, but I don't want to modify that file to make the changes. What is the correct way to do that?

  • Add methods to generated WCF client proxy code

    - by dcstraw
    I'd like to add one additional method for each service operation in my WCF client proxy code (i.e. the generated class that derives from ClientBase). I have written a Visual Studio extension that has an IOperationContractGenerationExtension implementation, but this interface only seems to expose the ability to modify the service interface, not the ClientBase-derived class. Is there any way to generate new methods in the proxy client class?

  • How to distort the desktop screen

    - by HaifengWang
    Hi friends, I want to change the shape of the desktop screen, so what are displayed on the desktop will be distorted at the same time. And the user can still operate the PC with the mouse on the distorted desktop(Run the applications, Open the "My Computer" and so on). I think I must get the projection matrix of the screen coordinate at first. Then transform the matrix, and map the desktop buffer image to the distorted mesh. Are there any interfaces which can modify the shape of the desktop screen in OpenGL or DirectX? Would you please give me some tip on it. Thank you very much in advance. Please refer to the picture from http://oi53.tinypic.com/bhewdx.jpg BR, Haifeng Addition1: I'm sorry! Maybe I didn't express clearly what I want to implement. What I want to implement is to modify the shape of the screen. So we can distort the shapes of all the applications which are run on Windows at the same time. For example that the window of "My Computer" will be distorted with the distortion of the desktop screen. And we can still operate the PC with mouse from the distorted desktop(Click the shortcut to run a program). Addition2: The projection matrix is just my assume. There isn't any desktop projection matrix by which the desktop surface is projected to the screen. What I want to implement is to change the shape of the desktop, as the same with mapping the desktop to an 3D mesh. But the user can still operate the OS on the distorted desktop(Click the shortcut to run a program, open the ie to surf the internet). Addition3: The shapes of all the programs run on the OS are changed with the distortion of the screen. It's realtime. The user can still operate the OS on the distorted screen as usually. Maybe we can intercept or override the GPU itself to implement the effect. I'm investigating GDI, I think I can find some clue for that. The first step is to find how to show the desktop on the screen.

  • Where to locate the unattend.xml schema

    - by Adam Driscoll
    I'm in need of a way to modify an unattend.xml file programmatically. It would be great if I could just serialize to and from an object. But to do so I would need to get a hold of the schema so that I can run it through XSD. The referenced link provides all the possible settings but it would be nice to have it in XSD format. Any ideas?

  • C# CodeDom - making project's forms accessible for scripts.

    - by michal
    Hi, I'm learning CodeDom scripting, I started with http://www.c-sharpcorner.com/uploadfile/mgold/codedomcalculator08082005003253am/codedomcalculator.aspx Now I'd like to allow script modify the project's form (for learning purposes only). I suppose I need to create new field for a class I'm generating which refers "this". However I have no idea how can I set a reference for script-accessible object ... ? Or can I directly publish some class member (like "this" or "button1") to a CodeDom script structure?

  • How work with common utils project.

    - by ais
    For example, I have some project Common.Utils.csproj and use it in all other projects. I can store its (Utils) sourses in one repository and modify it only there, register dll in gac and use it as dll in other projects, or I can clone sourse anywhere I need, include project in solution, use it as source and push modifications. So, what is best practice?

  • Url mapping with my servlet?

    - by user291701
    Hi, I'm using GWT with GAE. When the user enters any of the following urls, I want to just serve my app as usual to them: http://www.mysite.com/ http://www.mysite.com/dog http://www.mysite.com/cat the first case works by default. I'm not sure how to get the /dog and /cat cases to work. I think I have to modify something with the url mappings to get that to work in web.xml. Essentially I'm trying to just get my app served with any url entered: http://www.mysite.com/* Thanks

    Hi, I want to mix audio files of different size into a one single .wav file. There is a sample through which we can mix files of same size [(http://www.modejong.com/iOS/#ex4 )(Example 4)]. I modified the code to get the mixed file as a .wav file. But I am not able to understand that how to modify this code for unequal sized files. If someone can help me out with some code snippet,i'll be really thankful.

  • Is it possible to create a DateFormatter which converts a two-digit year into a four-digit year?

    - by DR
    In my Java application I use a DateFormat instance to parse date inputs. DateFormat fmt; fmt = DateFormat.getDateInstance(DateFormat.DEFAULT) // dd.MM.yyyy for de_DE The problem is that the user insists to enter dates in the form 31.12.11. Unfortunately this is parsed to 31.12.11. (0011-12-31 in ISO format) Instead I want the parsed date to become 31.12.2011 (2011-12-31 in ISO format). Can I modify the date format to somehow parse inputs that way?
