Kirat Please stop with those for loops. Don’t invent everything new. Know the API. List<String> valuesList = Arrays.asList(array).subList(x, y); String newValuesString = String.join(“,”, valuesList); 3 solved for loop iteration – how to avoid comma
If you open a file for update (+) and if you do one or more read operations, you must do a positioning operation (e.g. fseek()) before you do any writes. If you do one or more write operations, you must do a positioning operation (e.g. rewind()) before you do any reads. See POSIX’s specification of … Read more
You have a Console.ReadLine(); In your Loop. This “stops” the software and awaits user input, for example you can use this to get what the user typed. Long Story short: if you run your program und press repeatedly Enter it would work. I suggest changing it to foreach (string f in lines) { Console.WriteLine(f); } … Read more
Could the Rust program be written in an idiomatic way, to execute faster? Yes. To create a vector with a few elements, use the vec![] macro: let mut work: Vec<f64> = vec![0.0, 1.0]; for _x in 1..100000000 { work.swap(0, 1); } So is this code faster? Yes. Have a look at what assembly is generated: … Read more
Use the code provided in this answer to authenticate your code for the remote directory. Update: Additionally, the combination of escaped backslashes and verbatim strings is a bad idea. Use one of these but not both. Also, you are missing the backslash after the name of the shared folder. It should be like this: String … Read more

The preferred way is to use the css method: $(‘#yourImgID’).css({ width: ‘300px’, height: ‘150px’ }); If you must specifically add the width and height attributes to the <img> element, replace the css method with the attr method: $(‘#yourImgID’).attr({ width: ‘300px’, height: ‘150px’ }); solved Add Height and Width through jQuery [closed]
Currently I don’t believe it is possible to “embed” a screencast. You can add it as an attachment, but I don’t think that’s what you’re trying to do. Also, a better place to ask FogBugz related questions is here: http://support.fogcreek.com/?fogbugz (We aren’t able to check SO every day) solved Is it possible to add a … Read more
== is an operator, which, when not overloaded means “reference equality” for classes (and field-wise equality for structs), but which can be overloaded. A consequence of it being an overload rather than an override is that it is not polymorphic. Equals is a virtual method; this makes it polymorphic, but means you need to be … Read more
This article has a lot of details on how W3Techs gets their data: http://w3techs.com/blog/entry/usage_of_perl_for_websites_fell_below_1_percent As i did some analysis on this, let me summarize in short that the data presented by W3Techs is deeply flawed and extremely misleading. First off, it is important to know that they detect technologies of sites by running simple scripts … Read more
I believe the the theme is not calendar sorting. If so then do not allocate more memory using Calender object, add this method simply, public class ProgramItem { …. int getAsMins() { return hours *60 + mins; } } …. Collections.sort(items, new Comparator<ProgramItem>() { public int compare(ProgramItem item1, ProgramItem item2) { return item1.getAsMins() – item2.getAsMins(); … Read more
Use the appropriate FileSystemObject methods when handling paths: Set fso = CreateObject(“Scripting.FileSystemObject”) SCRIPT_PATH = fso.GetParentFolderName(WScript.ScriptFullName) SCRIPT_PATH = fso.BuildPath(SCRIPT_PATH, “Delete_App_Script.ps1”) For using variables inside strings you need to concatenate the variables to the rest of the string, as @Lankymart pointed out. This is also documented in the language tag info. objShell.Run “RUNAS /user:Domain\User “”powershell ” & … Read more
Rather than generating pi and searching for a certain sequence of digits, you’re best off simply saying yes all the time. There is no evidence for any sequence not being in pi. 3 solved How to generate all of the numbers of pi in Objective-C [closed]

You can get the first item of the list like so: Person p = pList[0]; or Person p = pList.First(); Then you can modify it as you wish: p.firstName = “Jesse”; Also, I would recommend using automatic properties: class public Person { public string firstName { get; set; } public string lastName { get; set; … Read more
