Using foreach on a string will produce a sequence of char, so declaring part as a string is not valid. Declare part as char or use var. do { //string test = questions[qCounter] = objReader.ReadLine(); string test = question.Split(‘?’)[qCounter]; qCounter++; foreach (char part in test) { Console.WriteLine(part); Console.ReadLine(); } } while (objReader.Peek() != -1 && … Read more
Ok here is the rewrite, the original code is better but this one might be easier to understand: #include <stdio.h> #include <string.h> int main() { char cur_char; char string[100]; int index = 0, count[255] = {0}; printf(“Enter a string\n”); gets(string); while (string[index] != ‘\0’) { char cur_char = string[index]; // cur_char is a char but … Read more
The function does not make sense. For starters it is unclear why you are using a pointer to the vector instead of a reference to the vector. Nevertheles, this declaration vector<unsigned char> vec(5); does not reseeve a memory for the vector. It initializes the vector with 5 zero-characters which will be appended with other characters … Read more
It is well documented in the manual. An iterator that points to the first of the newly inserted elements. In you case new_foo_it after listOfFoos.insert of a single element, points to the last element of the list, it points newFoo. 1 solved In this C++ code, what element of the list does the iterator refer … Read more
Try this: DWORD WINAPI ThreadProc1( LPVOID lpParameter) { … return 0 ; } DWORD WINAPI ThreadProc2( LPVOID lpParameter) { … return 0 ; } … typedef DWORD (WINAPI * THREADPROCFN)(LPVOID lpParameter); THREADPROCFN fntable[4] = {ThreadProc1, ThreadProc2, …} ; //Start the threads for (int i = 0; i < max_number; i++) { DWORD ThreadId ; CreateThread( … Read more
You should not execute delete on a node that is still in the linked list. First you need to rewire any references to it. That is to say, the node before should have its nextPtr redirected to the node after the one that is to be deleted, and that node should have its beforePtr redirected … Read more
The issue is that for each iteration of the for loop, the std::sort can potentially change the already sorted column. For example, if you sort column i, then columns i-1, i-2, etc. can lose the changes that were made to sort those columns. Without changing too much of your original code, and albeit not the … Read more
Oh wow, you are just starting with C++. So lets start with the std:: part. This is called a namespace. Namespaces are sometimes confusing people, but they are very useful. A namespace is just little container that can hold classes, enums, sturcts and all the other things in one place. Why are they useful? Well, … Read more
First of all, 1<<10 is an expression that can be calculated at compile time, and it equals 1024. So your code is equivalent to #include <stdlib.h> int main() { int num=0; while(malloc(1024)) ++num; } So what it does is to allocate chunks of 1024 bytes of memory until it fails to do so. Each time, … Read more
Turn this to false AutoGenerateColumns=”True” And add your own Bound columns to the Gridview. You will be able to give the columns whatever names you want solved variable name with a white space [closed]
I can’t well understand your question, but here I show you how to concatenate bits. byte bits2 = 0b_000000_10; byte bits6 = 0b_00_101100; ushort bits14 = 0b_00_10110010001110; uint concatenated = ((uint)bits2 << 20) + ((uint)bits6 << 14) + (uint)bits14; uint test = 0b_00_10_101100_10110010001110; if (concatenated == test‬) { Console.WriteLine(“Ok”); } 4 solved How to perform … Read more
You are not using the result of query IQueryable<StammdatenEntityModel> query = dbSet; query = query.OrderByDescending(s => s.CreateDateTime); query = query.Where(s => s.Deleted == false); if(!String.IsNullOrEmpty(keyword)) { query = query.Where(s => s.SerialNumber.Contains(keyword)); //simplified for SO } query = query.Skip(skip); query = query.Take(take); 0 solved IQueryable with Entity Framework – order, where, skip and take have no … Read more
The two likely problems that I can see without you adding the error code. is that you are missing the column names in your insert statement. is that a user is putting an apostrophe in one of your text boxes. This is a SQL Injection vulnerability. Try something similar to this instead: using (SqlConnection con … Read more
Create an .rc file to refer to the desired embedded .exe as an RCDATA resource, eg: MYEXE RCDATA “path\to\file.exe” Add the .rc file to your project. The referred .exe file will then be compiled into your final executable. You can then access the MYEXE resource at runtime using the Win32 FindResource()/LoadResource()/LockResource() functions, or higher-level framework … Read more
I’m not entirely sure what you’re doing, but you could do something along these lines to enforce an agent to use particular security. var protocol = require(‘https’); var configuration = { hostname: ”, port: 443, path: ”, method: ”, secureProtocol: ‘TLSv1_2_method’ } protocol.request(configuration, context => { // Request information such as body. }); Not sure … Read more
