• How can I clone a .NET solution?

  - by tobinharris

  Starting new .NET projects always involves a bit of work. You have to create the solution, add projects for different tiers (Domain, DAL, Web, Test), set up references, solution structure, copy javascript files, css templates and master pages etc etc. What I'd like is an easy way of cloning any given solution. If you use copy/paste, the problem is that you need to then go through renaming namespaces, assembly names, solution names, GUIDs etc. Is there a way of automating this? Something like this would be great: solutionclone.exe --solution=c:\code\abc\template.sln --to=c:\code\xyz --newname=MySolution I'm aware that Visual Studio has project templates, but I've not seen solution templates. Ideas welcome, thanks in advance folks!

• If I can't use datacontext in a static

  - by Richard77

  Hello, I've got this public static class MyClassHelper { DataContex db = new DataContext(); public static Type MyMethod() { //Do Something with db // such as db.myTable } } I'm getting the following error: "An object reference is required for the non-static field, method or property..." Is there anyway to get around this? How about this. I've an object that contains only integers, which is fine for all the internal functionings as it allows me to link tables. But occasionaly, I need to display some information to the user. That's why, I'd like to create a static method so it would read the integer, look up in the DB, and display a name instead of a number. I want it to be a static method so that I can use it in my View template. Thanks for helping

• I'm a PHP programmer. Should I learn Java to improve my skills?

  - by user326068

  I think the title says everything. I'm a PHP programmer. Maybe it's interesting that I do php programming at work, but that's not full time. I'm still a student until '12 and I'll go to university after this before I'll start with my real life as programmer. Now I'm asking myself whether it would be a good way to do some java to improve my skills in OOP and other things that are better in Java then in PHP and I can learn their to port them to PHP.

• Django: Converting an entire Model into a single dictionary

  - by LarrikJ

  Is there a good way in Django to convert an entire model to a dictionary? I mean, like this: class DictModel(models.Model): key = models.CharField(20) value = models.CharField(200) DictModel.objects.all().to_dict() ... with the result being a dictionary with the key/value pairs made up of records in the Model? Has anyone else seen this as being useful for them? Thanks. Update I just wanted to add is that my ultimate goal is to be able to do a simple variable lookup inside a Template. Something like: {{ DictModel.exampleKey }} With a result of DictModel.objects.get(key__exact=exampleKey).value Overall, though, you guys have really surprised me with how helpful allof your responses are, and how different the ways to approach it can be. Thanks a lot.

• increasing speed and efficiency of ajax call

  - by user1048824

  I'm not the most disciplined dev, dont know standards and am self-taught so bear with me. I create stuff very logically and fast but not always using 'programming standards'. I have a mobile app using geolocation API. it gets thousands of places from my db and makes gmaps v3 markers for the ones around the user's current location. there is an ajax call from my JS to an aspx page that calls the database, makes a json string, and sends the json string to the javascript that then creates the google map markers. would i save time if the json string was in a flat file? im not sure if, generally speaking, accessing a sql db from an aspx page is faster than c# file i/o on a flat file with pre-rendered JSON. (of course, using the flat file, it would update everytime the db is updated)

• Whats wrong with my CSS?

  - by William

  I'm trying to get my name and trip input fields to line, but they're all over the place. http://prime.programming-designs.com/test_forum/viewboard.php?board=0 #formdiv{ margin: auto; text-align: left; width: 30%; } .fielddiv1{ background-color: #222222; border: 2px solid #333333; vertical-align: middle; width: 45%; float: left; } .fielddiv2{ background-color: #222222; border: 2px solid #333333; vertical-align: middle; width: 100%; } .fieldtext{ width: 100%; background-color: #333333; }

• Understanding behaviour of read() and write()

  - by neo730

  hi i am a student and just start learning low level c programming.i tried to understand read() and write() methods with this program. #include <unistd.h> #include <stdlib.h> main() { char *st; st=calloc(sizeof(char),2);//allocate memory for 2 char read(0,st,2); write(1,st,2); } i was expecting that it would give segmentation fault when i would try to input more than 2 input characters.but when i execute program and enter " asdf " after giving " as " as output it executes "df" command. i want to know why it doesn't give segmentation fault when we assign more than 2 char to a string of size 2.and why is it executing rest(after 2 char)of input as command instead of giving it as output only? also reading man page of read() i found read() should give EFAULT error,but it doesn't. I am using linux.

• How would you find the height of objects given an image?

  - by Ram Bhat

  Heyguys.. This isn't exactly a programming question exactly. I just want to know what your approach would be to a common problem in Digital image processing. Lets say you have an image of a a few trees in say jpg format. How would you go about finding the heights of each of these trees. The photo is the only input you have. I want to know the approaches you have not code. So it doesnt matter if your answers are vague, or non DIP-ish.

• Django: Is it possible to attach media files (css, javascript etc) to a View-class?

  - by mrmclovin

  I can't fins any information on how to define css or javascript files in a view like: class MyView(View): .... class Media: css = { 'all' : 'mystyle.css' } If you have a form you can do like: class MyForm(ModelForm): .... class Media: css = { 'all' : 'mystyle.css' } And then in the template you can print the files like; {{ form.media.css }} I like that Syntax very much and I like to keep the View-specific css files in the app-directory. Does anyone know if it's possible? Thanks!

• Should I use polymorphic association, just a has_one, or attribute in this case?

  - by Angela

  I have three Models: Contact_Email, Contact_Letter, and Contact_Call. These represent the unique pairing of a Contact with a template for each of the three. For all of these, I want to record at least a status and date for the status. For example, "declined" on 5/10/10 or "responded" on 5/10/10 or something like that. I may in the future want to extend that. I later do want to be able to see all the instances that have the same status, such as "responded" or "meeting requested." What is the best way to do this? To make the three Contacts statusable and create a polymorphic association on a model called Status. Or just each Object of Contact_Email has_one Status?

• Can you ask Google how common a search is?

  - by John

  I'm not familiar with Google Analytics but I think you can use it to see how many people get to your site using different search strings. But if you don't yet have the site, can you simply ask Google how popular a search is? For instance say you're choosing a new product name/slogan/etc. First of all, you want to see if that is already very crowded, which is easy through just Googling it. But now you might want to see if anyone is actually searching for this... an ideal situation would be to find a search-string lots of people are using, which doesn't put your competitors on the #1 spot. Is this possible? Not exactly programming-related, but closely related to web-development IMO... please vote to close if you disagree, I won't be offended!

• Beginner's Language app

  - by Eiseldora

  Hi I'm a techie with no programing experience. I know html and css, but I'd like to someday be able to make an app for my phone (I have an android) and possibly mobile websites. I made learning a programing language and creating a mobile app a goal for my job, and now my boss would like me to pick a programing language to learn. I found a free open course from MIT (http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-00-introduction-to-computer-science-and-programming-fall-2008/) called introduction to computer science. In the course they teach python, but more importantly it seems they teach how to think like a programmer. When I told my boss about the free online course she didn't think that Python was an appropriate language for me to learn. She'd like me to learn a language that is more similar to one used to make Phone apps. Does anyone out there know a better language for me to pick up that would be similar to Android or iPhone's App language. Thank you

• Navigating sharepoint with a treeview

  - by linqmonkey

  I'm trying to replace the navigation on our sharepoint site with a treeview. It's a large site with up to 4 subsite leves in places. All I need it to do is show a consistent structure from page to page show only sites and pages The default sharepoint treeview seems to do neither of these things (doesn't display items from the parent site, includes document libraries but not pages). Does anyone have any idea how to achieve this? We're using the publishing site template throughout if that makes a difference. I've tried binding the tree to the datasource the quick launch uses but I guess from the error message they expect differently named properties.

• Starting out with Objective C; need some guidance

  - by alimaxwell

  Hi Everyone, I have started learning Objective C with no prior programming experience from the 'Become an X-Coder' eBook (http://download.cocoalab.com.s3.amazonaws.com/BecomeAnXcoder.pdf). My question is, if I want to be doing iPhone development, am I going in the right direction? Am I learning the wrong language, or should I be learning Cocoa Touch? As I said, I have no prior experience, and just need someone to point me in the right direction. Apoligies if I have put this in the wrong place. Thanks very much for your time.

• Shift from Java to c++

  - by zengr

  Hello, I have been developing applications based on C# (.net) and Java (J2EE) from the last 3 years. But, now I feel, Java, C# makes you lame (from learning point of view) and you can develop your apps quickly but you fail to understand the basic underlying concepts of programming. So, I am trying to learn C++, but I find it a little "confusing" due to pointer, multiple inheritance, some conventions and other concepts of C++ which don't exist in Java. So, what do you guys suggest? How should I got about it? Thanks PS: I am a student, so have all the time in the world and actually shift.

• Make a simulation using python

  - by user3727759

  I am new to programming and using python. What I am trying to do is create a simulation of a thermostat system by using python. Is there a way to create a program that I can input data, for example temperature and humidity values and then have python constantly plotting the data as I enter the values. This is to simulate a device gathering data and sending it to this program and having it being plotted. I have found ways to plot data by using matplotlib but I have not been able to find a way that I can input the data and have the plot upgrade constantly. Thanks any advise is appreciated.

• Language D compared to C++?

  - by Henrik

  Anyone here with experience of the language D? I was just reading through its presentation at http://www.d-programming-language.org/ and at Wikipedia and it seems like a good (better) alternative to C++. With good/better I mean that it seem simpler yet it has all the good stuff within C/C++. But without some of the difficulties that make C++ more difficult to learn and use in a good and efficient way. So anyone with comments/experience with the language D? Performance?

• Implementing an iterator over binary tree using C++ 11

  - by user1459339

  I would like to create an iterator over the binary tree so as to be able to use range-based for loop. I understand I ought to implement the begin() and end() function first. Begin should probably point to the root. According to the specification, however, the end() functions returns "the element following the last valid element". Which element (node) is that? Would it not be illegal to point to some "invalid" place? The other thing is the operator++. What is the best way to return "next" element in tree? I just need some advice to begin with this programming.

• Redirect to hash URL

  - by r1987

  I'm building a site with a hashchange on wordpress, all working good. It just loads a single.php template file into a div. The problem is that i can still access my single url (http://www.mydomain.com/my-single-post). Since its not having any head and style tags with it, i don't want people to go over there. Also google has picked up the direct links, because I use the href attribute to load content into the div. So my question is: If someone clicks a link lets say in a forum, http://www.mydomain.com/my-single-post , is it possible to redirect him instantly to http://www.mydomain.com/#my-single-post ? I have researched that it has something to do with .htaccess, but I also have Pages, where i don't want the hash infront of the page-name.

• C# - Silverlight - Custom control or UserControl ?

  - by cmaduro

  I need a button that is visually completely customizable, but has custom logic to publish events and manage it's visual state based on events it has registered for. When I say visually customizable, I mean I should be able to both create the button in xaml and set it's style by binding to the supplied style. Or I can create an instance of the button and set the style by passing a parameter to an alternate constructor. Or by calling a method on the button class to set the style. I do not plan on substituting the controls template, it should be a button. Can anyone point me to some code samples of this?

• iOS - How to pass information from the VIEW to the Controller?

  - by user1720503

  I am fairly new to programming in general, and have been following the CS193p videos on iTunesU. I am currently doing assignment 3, and am having trouble getting a bit of information from the View sent to the View Controller. I believe I have set up the whole delegation thing correctly, so the question really is to how to get my View Controller to see a bit of information (such as self.bounds.size.width), which is a property that only the View has. Would this involve using self.dataSource? And if so, through what means could I pass this bit of information? Thanks!!

• Tracking Useful Information

  - by Steve M

  What do the clever programmers here do to keep track of handy programming tricks and useful information they pick up over their many years of experience? Things like useful compiler arguments, IDE short-cuts, clever code snippets, etc. I sometimes find myself frustrated when looking up something that I used to know a year or two ago. My IE favourites probably represent a good chunk of the Internet in the late 1990s, so clearly that isn't effective (at least for me). Or am I just getting old? So.. what do you do?
