[ad_1] HttpContext.Current.Response.Redirect doesn’t return a string. I suppose you wanted to do: “<br /><a href=”https://stackoverflow.com/questions/63356491/CS_Activation.aspx?ActivationCode=”>Click here to change your password.</a>”; [ad_2] solved Operator ‘+’ cannot be applied to operands of type ‘string’ and ‘void’ C# WebMethod
[ad_1] Constants are stored in various places: Constants may be stored in a designated section of memory that is marked read-only for the program. In general-purpose systems, this is not ROM. ROM is physically read-only memory. ROM is typically used in special-purpose systems where the software is set prior to manufacturing the hardware (or at … Read more
[ad_1] “Protection Level” refers to the accessibility of a particular class member to contexts outside of that class. The types of protection level available in C# are private, protected, internal, protected internal, and public. Protection level is specified when you write the class. See below: class Class1 { private int privInt; protected int protInt; public … Read more
[ad_1] Your problems stem from this statement: scanf(“%c”,&user); The %c conversion specifier only reads a single character from the input stream, not a string. If you entered a username like jbode, only the ‘j’ character is read from the input stream – the remaining characters will be read by the next scanf (or other input) … Read more
[ad_1] Here you are: #include <stdio.h> #include <string.h> int main( void ) { const char *s = “ABCDEFGHIJKLMNOPQRSTUVWXYZ”; const size_t N = strlen(s); while (1) { printf(“Enter a non-negative number (0 – exit): “); size_t n; if (scanf(“%zu”, &n) != 1 || n == 0) break; size_t k = 0; for (size_t i = 0; … Read more
[ad_1] Make it a Click event handler, attach it to each button, and use the sender parameter as the button to change. void button_Click(Object sender, EventArgs e) { var button = sender as Button; if(button != null) { button.Text = “X”; button.ForeColor = System.Drawing.Color.Red; } } [ad_2] solved How to pass button object to function
[ad_1] #include <stdio.h> #define MAX_STRING_COUNT 1000 #define MAX_STRING_LENGTH 100 int main() { int n; char str[MAX_STRING_COUNT][MAX_STRING_LENGTH]; int ret = scanf(“%d\n”,&n); if (ret != 1 || n < 0 || n > MAX_STRING_COUNT) { puts(“Wrong number of strings!\n”); return 1; } for(int i = 0; i < n; i++) { ret = fgets(str[i], MAX_STRING_LENGTH, stdin); if … Read more
[ad_1] Just use DateTime.ToString(string) method like; datetime.ToString(@”dd\/MM\/yyyy”); Remember, “https://stackoverflow.com/” format specifier has a special meaning in custom date and time formatting as replace me current culture’s or specified culture date separator. If your CurrentCulture‘s DateSeparator is already /, you can use it without escaping like; datetime.ToString(“dd/MM/yyyy”); or you can provide IFormatProvider which has / as … Read more
[ad_1] I resolved this problem. So the problem is because I fill DataGrid again with Data. Instead that I don’t fill it I only get ID where I stopped from last time in that Table with some ID. Code for Button Continue: int postID; string fbGroupID; int listID = int.Parse(cmbSelectList.SelectedValue.ToString()); using (OleDbConnection connection = new … Read more
[ad_1] There are several things wrong with your program: vector<int> pies[p], racks[p]; Should be: vector<int> pies, racks; The reason is that the first definition declares an array of vector. That certainly can’t be right, unless you really want to declare an array of vectors. What you want to do is declare two vectors that start … Read more
[ad_1] Using explicit implementation of interfaces, you can do something like: public interface IMyClass { object this[int index] { get; set; } } public class MyClass : IMyClass { public string this[int index] { get { return “”; } set { } } object IMyClass.this[int index] { get { return “”; } set { } … Read more
[ad_1] The simplest way to share your program is compile it and share the binaries. There are a lot of open question you will have to solve (libraries dependencies, specific distribution configurations, …). You must to precompile for every targeted hardware architecture (x86-64, ARM, …) and for every specific SO (BSD, Linux, … even Windows). … Read more
[ad_1] You can use recursive templates and std::string::replace: #include <iostream> #include <string> template<typename Arg> void convertArgument(std::string &fmt, Arg arg) { int location = fmt.find(“%d”); fmt.replace(location, 2, arg); } template<> void convertArgument(std::string &fmt, int arg) { int location = fmt.find(“%d”); fmt.replace(location, 2, std::to_string(arg)); } template<typename Arg> std::string convert(std::string fmt, Arg arg) { convertArgument(fmt, arg); return fmt; … Read more
[ad_1] Let’s extract a method (ReadInteger) for it. Please, note, that we use int.TryParse instead of Convert.ToInt32 since user input is not necessary a valid integer private static int ReadInteger(String title = null) { if (!string.IsNullOrWhiteSpace(title)) Console.WriteLine(title); while (true) { if (int.TryParse(Console.ReadLine(), out int result)) return result; Console.WriteLine(“Sorry, the input is not a valid integer, … Read more
[ad_1] Your head parameter in insertNode function should be a reference (or a pointer to pointer to Node). Beacause in the current form, it is an input parameter, but you need to be in-out parameter. It means that in the current code, your aNode variable is NULL and is always stays NULL. I recommend this: … Read more
