问题 I want to list the files in this folder "C:\home\WORK\Desktop\Communication". There are ten files in this folder. My code has no error but it's not printing anything. What is my mistake ? #include<stdio.h> #include<Windows.h> #include<string.h> int main(int argc,char *argv[]) { char path[]="C:\\home\\WORK\\Desktop\\Communication"; strcat_s(path,sizeof(path),"\\*"); WIN32_FIND_DATA fdata; HANDLE hFind =INVALID_HANDLE_VALUE; int numberOfFiles=0; char *files[10]; hFind = FindFirstFile(path,

问题 So I've been having problems with this tutorial for SQL on the MDSN website. The first picture says what it should like to add a new file to the project but when I try to repeat the instruction on VS the service based database file is missing. Does anybody know what I should do? 回答1: Please try to this way: Go to Control Panel -> Uninstall a Program, select Visual Studio 201x, right click, Change -> Modify, and check whether you have installed "Microsoft SQL Server Data Tools", if you didn't

问题 I'm writing a program in C# using Microsoft Visual Studio, i need the program to match the vertical bar, but when I try to escape it like this "\|" it gives me an unrecognized escape sequence error. What am I doing wrong? 回答1: In C# string test = "\|"; Is going to fail because this is a C# string escape sequence, and no such escape exists. Because you are trying to include a backslash in the string, you need to escape the slash so the string actually contains a slash: string test = "\\|";

问题 There's a bug in the code somewhere that I can't find, some variables simply don't work somehow.

问题 I have a particular type of exception that I would like Visual Studio to not break on and show the Exception Assistant screen. Essentially I would like it just to let my normal exception handling infrastructure deal with it. The exception is an inheritor of System.Exception which I wrote and have the source code for. Any where this is thrown I want VS to not catch it, ie it is not useful to just supress a single throw new BlahException(); in code. This is because the exception is thrown a lot

问题 I am developing a .NET Standard library and plan to use it in both .NET Core and .NET Framework projects. My library is dependant on a third library which itself is dependant on a few C binary files. The C binary files have to be copied to the output directory of the project which will be referencing my library. I added the binary files to my library project as content and they are copied to the content and contentFiles directories when the NuGet package is packed with the dotnet pack command
