version

How can I compare two Version number strings? For example: 3.1.1 and 3.1.2.5.4 Now I need to find out if 3.1.2.5.4 is higher than 3.1.1 but I don't know how to do this. Can anybody help me? Thanks in advance! Sample Code : NSString* v1 = @"3.1.1"; NSString* v2 = @"3.1.2.5.4"; if ([v1 compare:v2 options:NSNumericSearch] == NSOrderedDescending) { NSLog(@"%@ is greater than %@",v1,v2); } From the Apple Documentation for Comparing and sorting strings . Paras Yes, you can compare the versions, please refer the code below: public class Comparision { string ver1, ver2; public static void main(String

I have a project using Entity Framework, but I am not sure which version of EF I am using. According to the Microsoft version history EF5 will install itself: If you create a new model using the Entity Framework Designer in Visual Studio 2012, the EF5 NuGet package will be installed to your project and the generated code will make use of EF5. However I did not create the EF-part of the project, but got it from version control (TFS). Now I am not sure how to determine if I have EF5. If I right-click on the References folder of the project and select Manage NuGet Packages, it show EF5 with an

I had Python2.6 on my Windows 7 and I just installed Python2.7. As a result I have "C:\Python26" and "C:\Python27". My problem is that system still tries to use the old version. For example if I type Python --version I get "Python 2.6.4". Or, if I try to install "numpy" it find the old version and does not allow me to manually change it to the new version. I tried to check system environment variables to find out if there is Python2.6 (to replace it by Python2.7) but I did not find anything like that. You need to change Python path to the new version. http://docs.python.org/using/windows.html

I installed SASS from the terminal, just gem install sass . And I see it says "Successfully installed sass-3.2.9." However, when I then do sass --version or sass --v I get this error: -bash: sass: command not found The only thing I can think of is, when I was doing the Git tutorials on Tuts+ I ran into a local vs. global issue or I had to edit a bash_profile file. This is what is inside the bash_profile file inside my user directory: export PATH="/usr/local/bin:$PATH" Any thoughts or tips on why I can't get the version of SASS or Compass I just installed? (I can only get ruby --version .) Leon

For example, [].map was "implemented in JavaScript 1.6." Is that an ES5 method? How does the 1.6 correlate to an ECMAScript version? There aren't really strict correspondences between the version numbers Mozilla uses and the ECMAScript standard's version numbers. There's a table on Wikipedia that might be what you're looking for -- you'll see that JavaScript 1.6 corresponds to ECMAScript 3 and then some additional extensions. [].map specifically was standardized in ECMAScript 5, but to my understanding, the feature was first introduced by Firefox before the ECMAScript 5 standard was even

N.B. I think answers are likely to be design-focused and therefore basically implementation agnostic, but I'm using Java+Hibernate with Postgres if there's some particularly well-suited solution using those technologies. I have a table with a particular field which will hold large strings, let's say blog posts which on average are +10000 characters. In my app, you can edit blog posts as many times as you like, and the latest version will always be displayed instantly after an update. However, the app needs to keep a full version history of these edits, so they can be viewed. An obvious
