问题 I have an image applied to a control in Visual Studio (in this case a PictureBox, but it could be a Button or any number of other controls). I would like to edit this image in a 3rd party program, but VS will not let any other program access the file while it is open. Even if I temporarily change the graphic to something else so that the image I want to save is no longer being used, VS will still not relinquish control of the file. So instead I have to shut down the entire project in order to

问题 Just installed Visual Studio 2017 – Enterprise Editio n with the following workloads: Universal Windows Platform Development ASP.Net and Web Development .Net Desktop Development .Net Core cross-platform Development After this installation, when I create a new .net core or .net standard project, the visual studio restarts while loading the project template. Steps to create the behavior: File ⇒ New Project ⇒ .Net Core ⇒ Asp.Net Core Application (.Net Core) Visual Studio tries to load the

问题 I'm trying to add a new comment to a work item which mentions a user, but using the traditional "@adamh" as you would do on the website does not seem to work via the API. The data updates fine, however the "@adamh" is just plain text, I need to be able to somehow chuck an identity into here. Can anyone point me in the right direction? Thanks! A snippet is here const vsts = require('vso-node-api'); const item = require('vso-node-api/WorkItemTrackingApi') const ti = require('vso-node-api

问题 I use Activator.CreateInstance to create class from Type. In case where constructor throws exception (That happens and is totally expected) it is caught by try..catch. But Visual Studio breaks as if it was unhandled. I managed to simplify this issue: Screenshot of VS Code in Tio using System; public class Program { public static void Main() { try { var foo = Activator.CreateInstance(typeof(Foo)); catch {} Console.WriteLine("Finished"); } class Foo { public Foo() { throw new Exception(); } } }

问题 My Program : To get input from the user about personal details and then output the information.

My Goal : To check the input for 'Phone Number' and make sure that the number is 10-digits. My Code : #include <iostream> #include <string> #include <limits> using namespace std; class Personal_Details { public: void setFirstName

问题 Visual Studio 2019 started showing Code Analysis warnings as in-editor green squiggles by default. These may be extremely useful for students learning C programming, because they catch classical mistakes, such as off by one array accesses. Unfortunately false positives may completely ruin the learning experience and I fear that I will have to ask the students to disable the feature in order to avoid having them worry on non existing problems. This short snippet doesn't cause any warning:

问题 According to docs.microsoft.com, I'm trying to get my form's IDesignerHost in design time: private static Form _findForm; protected override void OnCreateControl() { if (_findForm == null) { _findForm = FindForm(); } if (_findForm == null) { throw new Exception("FindForm() returns null."); } // NullReference //IDesignerHost dh = (IDesignerHost)_findForm.Site.GetService(typeof(IDesignerHost)); IDesignerHost dh = (IDesignerHost)GetService(typeof(IDesignerHost)); Console.WriteLine(dh == null); /

问题 My .Net Core project has a yellow triangle on dependencies, but when I open it up, none of the child entries have a yellow triangle. When I hover over dependencies, I don't see any tooltip telling me what's wrong. How can I check to see what is causing this yellow triangle to show up? I did what @oandreeeee suggested and increased the log level of my build and I noticed this: C:\Program Files\dotnet\sdk\2.2.104\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.ConflictResolution.targets(41,5):
