You could try the NuGet package GoogleMaps.LocationServices, or just spin of its source code. It uses Google’s REST API to get lat/long for a given address and vice versa, without the need for an API key. You use it like this: public static void Main() { var address = “Stavanger, Norway”; var locationService = new … Read more
Use SelectMany: public static IEnumerable<T> Concatenate<T>(params IEnumerable<T>[] lists) { return lists.SelectMany(x => x); }
The fact that it’s XML is basically irrelevant. You can save any text to a file very simply with File.WriteAllText: File.WriteAllText(“foo.xml”, xml); Note that you can also specify the encoding, which defaults to UTF-8. So for example, if you want to write a file in plain ASCII: File.WriteAllText(“foo.xml”, xml, Encoding.ASCII);
although you should put the variable into a managed pointer on it’s creation to do it from an existing pointer. int *a=new int; boost::shared_ptr<int> a_ptr(a); That said you most definitely do not want to be putting stack variables into shared_ptr BAD THINGS WILL HAPPEN If for some reason a function takes shared_ptr and you only … Read more
You cannot store arrays in vectors (or in any other standard library container). The things that standard library containers store must be copyable and assignable, and arrays are neither of these. If you really need to put an array in a vector (and you probably don’t – using a vector of vectors or a vector … Read more
Here is another way to format floating point numbers as you need it: string.Format(“{0:F1}”,6.33);
This sort of statement is ridiculous; people making it are either incredibly uninformed, or incredibly dishonest. In particular: The speed of dynamic memory allocation in the two cases will depend on the pattern of dynamic memory use, as well as the implementation. It is trivial for someone familiar with the algorithms used in both cases … Read more
Basically your question boils down to “is it reasonable to have [free library xyz] as a dependency for a C++ open source project.” Now consider the following quote from Stroustrup and the answer is really a no-brainer: Without a good library, most interesting tasks are hard to do in C++; but given a good library, … Read more
You can use regex groups to accomplish that. For example, this regex: (\d\d\d)-(\d\d\d\d\d\d\d) Let’s match a telephone number with this regex: var regex = new Regex(@”(\d\d\d)-(\d\d\d\d\d\d\d)”); var match = regex.Match(“123-4567890”); if (match.Success) …. If it matches, you will find the first three digits in: match.Groups[1].Value And the second 7 digits in: match.Groups[2].Value P.S. In C#, … Read more
Views are not supposed to pull data from somewhere. They are supposed to use data that was passed to them in form of a view model from the controller action. So if you need to use such data in a view the proper way to do it is to define a view model: public class … Read more
