[Solved] regular expression to replace div [closed]

by

This solution uses 2 Replace calls which might be OK if the code is not executed too frequently: string input = @”<div class=””tr-summaryinfo””>’ <p class=””tr-summaryitem””>test </> </div>”; string result = Regex.Replace(input, “<div class=\”tr-summaryinfo\”>(.*?)</div>”, “<ul class=\”tr-summaryinfo\”>$1</ul>”, RegexOptions.Singleline); result = Regex.Replace(result, “<p class=\”tr-summaryitem\”>(.*?)</p>”, “<li class=\”tr-summaryitem\”>$1</li>”, RegexOptions.Singleline); Note that you need ? in the patterns to avoid the … Read more

[Solved] std::map crashes when doing m[0] [duplicate]

by

Unfortunately (thanks C!) it is “possible” to construct a std::string from the integer 0, because it counts as a null pointer literal. However, it’s not really possible: Constructs the string with the contents initialized with a copy of the null-terminated character string pointed to by s. The length of the string is determined by the … Read more

[Solved] My code return cannot implicitly convert int to bool

by

You can’t test multiple values this way, you have to specify the test value each time: CssClass = (idee.IdTypeEtatIdee == (int)EnumTypeEtatIdee.example? “example” : (idee.IdTypeEtatIdee == (int)EnumTypeEtatIdee.exampletwo ? “Aletude” : (idee.IdTypeEtatIdee == (int)EnumTypeEtatIdee.examplethree? “Encours” : (idee.IdTypeEtatIdee == (int)EnumTypeEtatIdee.examplefour ? “examplefour ” : (idee.IdTypeEtatIdee == (int)EnumTypeEtatIdee.examplefive ? “examplefive ” : “null”))))) You could instead use a switch … Read more

[Solved] How do I convert ‘Single’ to binary?

by

The example expected value you’ve provided is just a straight binary representation of the number, however while probably not the most efficient way if you wanted to get the IEEE-754 representation of the number in binary you could use BitConverter.GetBytes as in the following example: Sub Main Dim i As Int32 = 1361294667 Console.WriteLine(ObjectAsBinary(i)) Dim … Read more

[Solved] positioning pie slice problems

by

I’ve revamped this and created a method out of it. I did the following to fix my issue. Firstly, I got rid of the process that converted the beginning and ending angles from degree to radians by creating another function that does converts just the ending angle to radians. After Circular_arc is called, I set … Read more

[Solved] Add records to List

by

You could do something like this (not tested): public List<CharactersOnline> charactersOnline = new List<CharactersOnline>(); var characterOnline = new CharactersOnline{connectionId = 1, characterId = 2, characterName = “test”}; //creates a new instance of your object charactersOnline.Add(characterOnline); //adds the single new instance of your object to the list solved Add records to List

[Solved] Decrementing a pointer with an unsigned “negative” number

by

[Edit] This is the answer to a previous version of the question, which showed the problem in action when calling these functions with argument dist==1 -(unsigned long)1 is well-defined and wraps around. It’s just ULONG_MAX. For the same reason, -(unsigned int) is UINT_MAX. Pointer arithmetic outside array bounds causes Undefined Behavior, so it’s perfectly reasonable … Read more

[Solved] C# List sorting with multiple range

by

you can use the Sort overload accepting a Comparison. This should work: public static int MyCompare(double x, double y) { if (x >= 0.0 == y>=0.0) // same sign, compare by absolute value return Math.Abs(x).CompareTo(Math.Abs(y)); if (x < 0.0) return 1; return -1; } usage: var list = new List<double>(); // fill your list // … Read more

[Solved] Getting average values from one Array to another Array [closed]

by

Maybe something like this could work… Did this on my mac in sublime text so you’ll still have to work with. Should get the point though. public class Foo { List<int> main = new List<int>(100); List<int> rollingAverages = new List<int>(100); public void Add(int score) { main.Add(score); if(main.Count > 10) { int rollingAverage = AverageLast10(); rollingAverages.Add(rollingAverage); … Read more
