问题 I was just wondering, why would somebody want to create multiple projects in one solution, if he could just as easily create a new solution for each project. What are the best practices/arguments in deciding which setup is better? 回答1: Multiple projects in one solution is very common. The norm even. It's very rare an entire program can be captured in one project. A simple example is unit tests. You typically want those in their own project, but the same solution so they remain easily

问题 I want to set up a project which uses OpenCV. So basically, I have to add a new property sheet using the property manager from Visual Studio 2010. Basically, I have to add the path to my include and lib folders in order to make OpenCV functional. I want to put my project in a git repository and I don't want to change the paths in my property sheets every time. Is there a way of using a system variable in my property sheet with the path to the build folder of OpenCV? If there exist a way of

问题 I'm trying to read a text file but nothing is coming out. I feel like maybe It's not linking correctly in my Visual Studio Resources folder but if I double click it - it opens fine in visual studio and it doesn't run into any problems if I test to see if it opens or if it is good.

问题 We have a TFS build definition set up where we pass the following extra MSBuild arguments in: /p:DeployOnBuild=true;DeployTarget=PipelinePreDeployCopyAllFilesToOneFolder;_PackageTempDir="\\server\build";AutoParameterizationWebConfigConnectionStrings=false This has been detailed elsewhere as a way to have the published files copied to a specific location instead of generating a deploy package. This unfortunately does not work on our build server, however if I run the exact same msbuild command
