问题 As the title of the question, I need to validate regex using the following values​​: (Maximum 2 decimal places, and 9 integers) with an optional percent symbol.

问题 I am fairly new to programming and compilers. I had a 1 year C++ class in university. Last month I started a project where I wanted to automate some processes for work. The program takes a phone directory and then creates .cfg files from it. Nothing very advanced, mostly reading, storing and writing data. I made my project using Dev C++ IDE. It works fine and it is simple to use for a beginner like me. Lately I was trying to use a Visual C++ function called GetOpenFileName. I got an example

问题 Having an ASP.NET Core project running on 2.1 LTS, I want to stay on LTS versions. So I'm not updating on 2.2 or 3.0 (both currently EOL) but an upgrade to 3.1 (next LTS) is planned in the future. Currently I want to stay on 2.1 LTS, which is still supported up to August 21, 2021. The NuGet package manager of VS 2019 show me a lot of updates for 2.2! I have to check every single update if there are any 2.1.x fixes like in this example: Here I have 2.1.11 installed and there is 2.1.16. I'd

问题 I am using VS 2010 and trying to integrate my two different website projects. I am able to add both of them under a single solution. By default the start up projects is the already present project. But I am not able to redirect the web pages of project 2 from the first project. I am also unable to find the namespaces of the project. And while adding reference it is not allowing the solution file to be added. Any help in this regard will be helpful. Edited: I have attached a snap as well. As

问题 Now that .net core support WinForms projects, I've ported an old project to .Net 5. I can edit code, desing GUI and compile, and everything seems to work fine except for Document Outline window (in Visual Studio 2019). All four buttons, move up, down, out and into, are disabled, so I cannot choose what to see on top at desing time. I have created a new project from the scratch and those controls are still disabled. Demo image: Any idea why? I can guess it's something microsoft is working on,
