Not quite clear on your code, but when you remove an element from an ArrayList that you are iterating through, you do not want to increment the index, otherwise you will skip elements, e.g.: ArrayList<…> list = …; for (int i = 0; i < list.size(); ) { if (shouldBeRemoved) list.remove(i); else ++ i; } … Read more
Really, you are asking two different questions. Entity Framework is not a database administration tool and as such does not have any functionality for directly loading data from a spreadsheet. If you research each part of your question separately, you might have more luck. Seeding data with Entity Framework Reading Excel Files with C# Reply … Read more

for j in xrange(10,40,5): What this loop will generate? 10,15,20,25,30,35 Notice, it will generate 10 but not 40 as the first param is inclusive, but second one is exclusive. Then which of them is not divisible by 3? 10,20,25,35 Simple as that. For your added question, see this: for char in “ABC 123”: print char, … Read more
Yes there are. Search for “bigint” on crates.io and there are plenty of results. They are not in the standard library but that’s nothing unusual for Rust. Rust’s standard library is kept small intentionally to minimise binary size ease maintenance (among other reasons). Because Rust is not Python, and there’s no reason for it to … Read more
I can’t express how strongly I wouldn’t recommend this – just DON’T This will get your app rejected from the App Store in the Apple App Store Review Process. If you insist on it though you could use exit(0); If the user wishes to exit your app they have the Home button at the bottom … Read more
First, let’s define what we need. We need a table (view) with these fields: ProductId, ProductName, ProductViewCount, and RootCategoryId. Imagine, the Category table has RootCategoryId field already. Then we can use this query to receive the result: SELECT P.Id AS ‘ProductId’, P.Name AS ‘ProductName’, PVC.ProductViewCount, C.RootCategoryId FROM Category C INNER JOIN ProductCategory PC ON PC.CategoryId … Read more
super() calls the parent constructor of the class and this() calls the constructor defined within the class. //Example of super() class parent { parent() { } } class child() { child() { super(); //Go to parent class constructor } } //Example of this class test { test() { this(“a”); //go to test one argument constructor … Read more

DISCLAIMER First read: https://stackoverflow.com/a/1732454/7939871 This parsing with a sed Search-and-replace Regular Expression is a shortcut interpretation. It is in no way for use in any kind of production setup; as it would break on so many valid HTML syntax or layout variations like: … Read more

Extend the capturing group around the “one or more not white space” LinkParser = new Regex(@”\b(?<url>https?://\S+)[‘””]”, RegexOptions.Compiled | RegexOptions.IgnoreCase); Then access the match collection with m.Groups[“url”].Value A simpler pattern might also work well: \b(?<url>http.*?)[‘”] These are very primitive and I wouldn’t guarantee it works in all cases. If you have urls that aren’t quoted at … Read more

The first error is a typo you wrote pememory. The second error appears because you didn’t code any transformation between Float and ptrFloat. You should add a copy constructor to Float: Float(const Float& a) : Float(*a.fmem_top) {} And then a conversion constructor to ptrFloat: ptrFloat(Float a) : Float(a) { pmem_top=pmemory; *pmem_top=abc; pmem_top++; } PS: your … Read more

string *ptr = new string(“Hello”); The new operator mainly does two things: It allocates enough memory to hold an object of the type requested. (In the above example, it allocates enough memory to hold this string object) It calls a constructor to initialize an object in the memory that was allocated. Now this “new” is … Read more
