[ad_1] The div tags are a part of your DOM, therefore you can remove them with Javascript. If you wish to hide “.loading”, you can do it after the page has loaded by adding this event to your Javascript: window.onload = function () { $(“.loading”).hide(); } Comment if that’s not what you are looking for. … Read more
[ad_1] Please look if this program can help you. It takes the two strings as arguments from the command line. #include <stdio.h> #include <stdlib.h> #include <string.h> int *substring(char *s, char *t) { int strlen1 = strlen(s); int strlen2 = strlen(t); int len = strlen1 < strlen2 ? strlen1 : strlen2; int i, j, k; int … Read more
[ad_1] The best practice for async/await is to use async “all the way down” (unless you really and truly don’t care about Method1 waiting for Method2 to complete). It’s possible to mix Task.Wait (or similar constructs) with async code, but it’s a bad idea because it can lead to deadlocks. The best thing here would … Read more
[ad_1] As your JavaScript causes a navigation you need to wait for the new page to load. You can use something like the following to wait for the page load. // create a static class for the extension method public static Task<LoadUrlAsyncResponse> WaitForLoadAsync(this IWebBrowser browser) { var tcs = new TaskCompletionSource<LoadUrlAsyncResponse>(TaskCreationOptions.RunContinuationsAsynchronously); EventHandler<LoadErrorEventArgs> loadErrorHandler = null; … Read more
[ad_1] Several of the errors mention that class IOBuffer has no member named “pack”. The message is absolutely correct, it doesn’t; if you look at the header, it has a method named Pack, with a capital P. C++ is case-sensitive! The errors about “redefinition” are happening because your include files don’t have include guards to … Read more
[ad_1] list is one of the many classes provided by the Standard Library. It behaves like any other class type: int : integer int* : pointer to integer Observer : Observer instance Observer* : pointer to Observer instance list<Observer> : list of Observers list<Observer*>* : pointer to list of pointers to Observers [ad_2] solved Difference … Read more
[ad_1] However, I still don’t understand why I’m unable to declare and initialize a private variable inside the constructor while declaring the variable without a public/private modifier works just fine. This is just the way the C# spec is written. Class-level instance variables (public or private) cannot be declared inside class methods or constructors. Check … Read more
[ad_1] According to this answer, the minimum (emphasis mine) ranges of an integer is -32,767 to 32,767. The actual limits are implementation defined, and are most likely from -2 billion to positive 2 billion. To check the integer limits on your device, you could use the header <limits> as follows: int imin = std::numeric_limits<int>::min(); // … Read more
[ad_1] This may help you below code contains for both to get and post data: public static string PostContent(this Uri url, string body, string contentType = null) { var request = WebRequest.Create(url); request.Method = “POST”; if (!string.IsNullOrEmpty(contentType)) request.ContentType = contentType; using (var requestStream = request.GetRequestStream()) { if (!string.IsNullOrEmpty(body)) using (var writer = new StreamWriter(requestStream)) { … Read more
[ad_1] You need to convert your std::string to a std::uint16_t. I’d recommend a stringstream std::istringstream ss(string); // maybe pick a different name std::uint16_t port{}; ss >> port; address.sin_port = htons(port); Be sure to #include <sstream> 2 [ad_2] solved Passing std::string as parameter gives error – htons function
[ad_1] Powers of 2: 2, 4, 8, 16, 32, 64, 128, 256… Last digits: 2, 4, 8, 6, 2, 4, 8, 6… Last digit of 2^i is: int arr[4] = {2, 4, 8, 6}; return arr[(i-1)%4]; 6 [ad_2] solved Finding the last digit of a very large 2^n number [closed]
[ad_1] I solved the problem. Actually the problem was I didn’t have a using directive to System.Data.Entity namespace at the top of my class. Even thought I could use “Include(“PropertyName)” name in my query, I couldn’t use “Include(x=> x.Childs)”. But after adding “using System.Data.Entity” on top of my class I can use “Include” in these … Read more
[ad_1] Have a look at the unmanaged API functions GetSystemPowerStatus and SetThreadExecutionState. Using a (thread) timer, you can periodically update the status, e.g. from a class property, and inform the system about your requirements. This is useful, if your application may allow or disallow the screensaver, depending on it’s operating state. public class PowerManager : … Read more
[ad_1] If you just want to open email client window for sending a message, you can use this: Process.Start(“mailto:” + emailAddress + “?subject=” + subject + “&body=” + body); However, if you just want to send email without any input from the user, best bet would be to send directly via SMTP server.
