I think you’re looking for something like the “Gradient Brush”. Head to the properties window, then to the “brush” section and finally to the “gradient brush”. You could check out the msdn link and also the developer nokia link. solved How to make font color as on picture [closed]
You can use an array of type record to store multiple books. Sold being your inbuilt function, you can try this: struct record { int bookId; int qtyInStock; }; typedef struct record Record; void sold(int id, Record* records) { int i; for(i=0;i<3;i++) { if(records[i].bookId == id) { records[i].qtyInStock–; } } } void updateId(int id, int … Read more
A possible approach. Find the convex hull of these points. Then find the two vertices which are the furthest apart. This gives a first diagonal. Then find the two other vertices that are the farthest from the first diagonal. This gives a second diagonal. Now you can just use the quadrilateral formed by these four … Read more
Finally, after a lot of head-scratching, I think I’ve solved this issue. Firstly, I had to add some additional WinAPI methods: [DllImport(“kernel32.dll”, SetLastError = true)] private static extern IntPtr GetStdHandle(int nStdHandle); [DllImport(“kernel32.dll”, SetLastError = true)] private static extern bool GetConsoleScreenBufferInfoEx( IntPtr hConsoleOutput, ref ConsoleScreenBufferInfoEx ConsoleScreenBufferInfo); [DllImport(“kernel32.dll”, SetLastError = true)] private static extern bool SetConsoleScreenBufferInfoEx( IntPtr … Read more
As other’s have mentioned, this isn’t very clear. Although I think I understand your issue, I can’t relate it to the context without an example of what you’ve tried already. Anyway, you can use regex for this. using System.Text.RegularExpressions; Then, assuming you’ve stored the input as a variable, let’s say “userInput” Convert.ToInt32(Regex.Replace(userInput, “[^0-9]+”, string.Empty)); This … Read more
I believe your error is in your input file: you read i and j and use it to access your arrays, without verifying that these value are within expected boundaries. For instance, if you improve your questioned code with an error message, like: for (k=0; k<M; k++){ input>>i>>j>>V; if (i>=N || j>=N) { cerr << … Read more
Try this code : #include <stdio.h> int main(void){ int array[10] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}; int counter=0, c, position; while ((c = getchar()) != EOF){ if(c == ‘ ‘ || c == ‘\n’ || c == ‘\t’){ array[counter]++; counter = 0; } else { if(counter<9) { counter ++; } … Read more
curl uses GNU autotools to be built from source. There’s a library to be built and configured, for the example program and header file, to link against. The error : Error 119″C:\Users\Sisitha\Documents\CCS C Projects\ Testing\curl\curlbuild.h” Line 556(145,183): ” Unknown non-configure build target” Suggests that the curl.h you included, hasn’t been configured, by the standard GNU … Read more
Look at your ConfigForm. Here’s your problem: public ConfigForm() { InitializeComponent(); Form1 frm1 = new Form1(); frm1.NewPath = NewPathBox.Text; } What you’re doing on your Form1 (which I’m guessing is your Main form) is creating a new instance of your ConfigForm and showing it. What you’re doing in your ConfigForm is creating a new main … Read more
You don’t show this in the code posted, but it appears you have two different definitions for black_screen, one global and one inside the main function. The one inside main has been initialized properly, but the global one is a bad pointer. The segmentation fault is the result of undefined behavior from dereferencing the bad … Read more
See, as in your program you haven’t initialised char c; It must be initialised or hold some value before being printed! int i; char c; i = 1; cout << c << endl; // initialsise c=something of char-type; c = i; cout << c << endl; //as initialised,so prints something Second, as you have initialised … Read more
Try SignalR or maybe SocketIO and see how they do ? I talked to the best guy I know in networking and he said that You should not disable ICMP totally, but instead be very careful if changing ICMP at all. Use WSS (ssl/tls), since routers will let that traffic through Out of scope, but … Read more
You should separate your classes and use the nested classes as property types. namespace WindowsFormsApp { class Car { public Id Id { get; set; } public Tires Tires { get; set; } } public class Id { public string brand { get; set; } public string model { get; set; } public int year … Read more
Do not use this answer, just use Select() method much simpler. class Program { static void Main(string[] args) { string[] s = new string[] { “hi”, “hello”, “what’s up” }; string[] newS = s.ArrayTo<string>(x => x.Remove(0, 1) ); foreach (string str in newS) Console.WriteLine(str); } } static class Ext { public static T[] ArrayTo<T>(this T[] … Read more
I would do something like this: char const* sep = “”; // item separator (nothing to begin with) for(a;a<=b;a++) { if(a%3 == 0 && a%2 != 0) { cout << sep << a; // output the separator before the next value sep = “, “; // now change it to a comma } } cout … Read more
