[ad_1] It’s better to store sql server connection string in your configuration file (if you are on .net framework then it’s App.Config for desktop apps and Web.Config for web apps) which you can update independently from your compiled app. And then you will be able to connect any sql server you have access to. 0 … Read more
[ad_1] You can solve your problem by grouping objects by Id1 and Id2. By the way, you sould share the test model and initialize the collection on problem definition next time ? internal class TestModel { public TestModel(string id1, string id2, string value) { Id1 = id1; Id2 = id2; Value = value; } public … Read more
[ad_1] You did not specify a type for the parameter of your function. Likely types are int* or char*, but you haven’t given enough information to perfectly deduce the type. bool checkWin(/*You MUST specify a type here!*/ spaceleft) Example: bool checkWin(int* spaceleft) [ad_2] solved How can I check if an element in an array is … Read more
[ad_1] You need to go from l to m when filling vector L: void merge(vector<int>& a, int l, int m, int r) { vector<int> L; vector<int> R; for (int i = l; i <= m; i++) L.push_back(a[i]); … } Otherwise L contains additional elements outside the range of interest. Then, index k steps off the … Read more
[ad_1] Why does this work?Does the ANSI translate values that are written in hex “form” into their decimal equal when used in mathematical functions? [ad_2] solved Why does this work?Does the ANSI translate values that are written in hex “form” into their decimal equal when used in mathematical functions?
[ad_1] Based on the comments and the originally posted code (it has now been fixed [now deleted]) there was previously a coding error (i++ missing) that stopped the C++ program from outputting anything. This plus the while(true) loop in the complete code sample would present symptoms consistent with those stated in the question (i.e. user … Read more
[ad_1] Something like this will provide a basic console output of your board. foreach (var cell in board.Cells) { int x = cell.Column; int y = cell.Row; Console.SetCursorPosition(x * 2, y * 2); Console.Write(cell.Value.HasValue ? cell.Value.Value.ToString() : ” “); } Console.ReadKey(); I’m multiplying the X and Y by 2 for the purpose of separating the … Read more
[ad_1] var result = studentList .Join(markList, m => m.Id, s => s.Sid, (s, m) => new { s, m }) .GroupBy(t => t.s) .Select(g => new { Student = g.Key, MarksCount = g.Count(), Marks = g.Select(x => x.m).ToList() }) .ToList(); MarksCount – total marks for this student Marks – List of marks for this student … Read more
[ad_1] This doesn’t look right: [XmlArray(“Pages”)] [XmlArrayItem(“Page”, typeof(SiteSource))] <– should be typeof(Page)? public SortableBindingList<Page> Pages 1 [ad_2] solved XmlSerializer Giving a Null exception in c#
[ad_1] Building on what @Aditi Rawat said, I’ve wrote a little program that does what you need using the quadratic roots formula. Not sure if you need to do it that way or not but this solves the problem: #include <iostream> #include <cmath> using namespace std; int main() { double a, b, c; cout<<“Enter a: … Read more
[ad_1] yes, a PVF can have parameters. virtual void playCard(Player enemyPlayer) = 0; here = 0 (is not assigning), Simply we are informing to compiler that function will be pure and does not having any body(where its declared, in that class), but it can have parameter. From the n4659 C++ standard A pure virtual function … Read more
[ad_1] Let me try to answer your questions. Yes. There is no reason why you can’t. You need to write some sort of lexer to turn the expression into tokens. Then you can use the shunting yard algorithm to turn the expression into something you can easily evaluate. Use the result from (2) and evaluate … Read more
[ad_1] To start a different software than your own program (with or without arguments) you can use system() from <cstdlib> header. #include <cstdlib> int main(int argc, char* argv[]) { system(“start putty -ssh user@server -pw password”); return 0; } If you want to evaluate the arguments to your own program, you can use argv[]. argv[0] holds … Read more
[ad_1] In the method h(), the while forms an infinite loop if the atk!=10. so you need to specify an exit condition there to break the loop; you can use like this: public void h() { while (Atk != 10) { this.Atk = random.Next(11); } Console.WriteLine(Atk); } Now you will get a random number between … Read more
[ad_1] You probably want this: #include <stdio.h> #include <string.h> int main(void) { char temp[256]; char *st[3]; // array of three pointers to char for (int i = 0; i < 3; i++) { scanf(“%255s”, temp); // prevents potential buffer overflow st[i] = strdup(temp); } for(int i = 0; i < 3; i++) { printf(“%s\n”, st[i]); … Read more
