C++ destruction is deterministic, garbage collection is not. In C++ you can guarantee when destructors will be called, in Java there is no such guarantee at all. In fact, your destructors might never be called in Java. 3 solved What is the difference between Java Garbage collection and C++ object destruction? [closed]
SO is not a website when you throw everything here and expected people finish the job for you. Anyway, to give you some hint, I give you a straight suggestion: Select CostGroupId From CostGroups Where CostGroupType = 1 –> Stored these in A collection, like an array: var costGroupsIdArr = ctx.CostGroup.Where(x=>x.CostGroupType == 1).Select(x.CostGroupId).toArray(); Then from … Read more
Is there any specific reason not use std::string ? A solution, using std::string would be: #include<iostream> using namespace std; void setKey(string& keyPress); int main() { string keyPress; setKey(keyPress); //rest here } void setKey(string& keyPress) { cout << “Enter the day using the number keypad: “<< endl << endl; cin >> keyPress; cout << endl << … Read more
In opener click event you have not added the # before dialog-model. The click event should like below. $(‘#opener’).click(function(){ $ (“#dialog-model”).dialog(‘open’); }); JS Fiddle: http://jsfiddle.net/azim101/6tvoma2c/ 1 solved jquery messagebox get from button click mvc4
Put this outside your “main” method to get make sure the user gives a number. private static int GetNumber(string request) { bool succeeded = false; Console.WriteLine(request); string reply=””; while(!succeeded) { reply = Console.ReadLine(); try { int.Parse(reply);//Attempt to convert “reply” into an integer. succeeded = true; } catch { Console.WriteLine(request+” (make it a number)”); } } … Read more
You could do that with a simple Regex, But you should really read some MSDN articles before you try to “use them” // Match a Regex and Do Stuff public void showMatch(string input, string expr) { MatchCollection mc = Regex.Matches(input, expr); int num = 0; foreach (Match m in mc) { string tm = m.ToString(); … Read more
Ultimately, this is because some base-10 numbers (like 0.9) cannot be represented in base 2 in a finite number of digits, just like the fraction 1/3 cannot be represented in base 10 in a finite number of digits (you get 0.333…). 0.9 converted to base 2 is 0.1110011001100…, and this binary representation gets truncated such … Read more
Your question is very broad and ambiguous, but I will attempt to provide an answer to what I think you’re looking for: Assuming you already have an .xap file (that is, the file produced by building a Silverlight Application in Visual Studio 2010), you can simply embed it in any HTML or ASPX page by … Read more
How about: \d{1,2}(?:[.,]\d{1,2})? explanation: \d{1,2} : one or two digits (?: : start non capture group [.,] : . or , \d{1,2} : one or two digits )? : end group, optional 1 solved Custom regular expression [closed]
A simple solution: int[] card1 = nums.OrderBy(it => Guid.NewGuid()).Take(6).ToArray(); Ordering the original array by a new guid should give you a decent approximation of randomness while avoiding the requirement to explicitly guard against duplication. Then you just take the first 6 results. Warning: The random-like behaviour of ordering by guid is an implementation detail of … Read more
[&](int n) {} means that in the lambda block you capture every variable from the scope by reference in contrast for example to [=](int n) {} where you have an access by value. You could also specify excactly what variable you need to be passed by reference or by value [&a, b](int n) {} PS. … Read more
Yes, a B can access protected members of an A. But it’s the fact that you’re going through v3 that makes it essentially irrelevant that this attempt is made from within a member function of B. It’s v3 trying to make the access, not B::calculate, and v3 is not a B&. [C++11: 11.4/1]: [..] All … Read more
You can use this possible way: using System; using System.IO; namespace CreateFile { class MainClass { public static void Main (string[] args) { Console.WriteLine (“Enter the File name:”); string filename = Console.ReadLine (); FileInfo fi = new FileInfo(@”G:\New folder (5)\” + filename + “.txt”); //You can use any extension to create respective file.

At first glance, this appears to simplify to if (a == 0) a = b; However, if a is a NaN, this simplification gives different results. Any comparison with a NaN is false, so the more complicated expression will assign b to a if a is zero or a NaN. 2 solved Need explanation of … Read more
