Determines whether changed files automatically save when building a project or its solution. It also determines the maximum number of Visual C++ projects that can build at the same time and certain default behavior on Run. Click Options, Projects, and Solutions, and then Build and Run on the Tools menu to access this dialog box.
Save All Changes
Automatically saves changes to the solution file and all project files that were changed since the last build when you press F5 or click Start on the Debug menu or Build on the Build menu. No prompt is given. Items are saved with their current names. By default, this option is enabled.
Save Changes to Open Documents Only
Automatically saves changes to all open documents when you press F5 or click Start on the Debug menu or Build on the Build menu. No prompt is given.
Prompt to Save All Changes
When selected, it displays a dialog box that asks whether you want to save changes to the solution and project items when you press F5 or click Start on the Debug menu or Build on the Build menu. The Save As dialog box is displayed so you can assign a name and location to your project. The project runs by using the memory image that contains your changes, but the changes are not saved if this option is not selected.
Don't Save Any Changes
The integrated development environment (IDE) runs the code version in the open documents and does not save changes to open documents when running the project.
Maximum Number of Parallel Project Builds
Specifies the maximum number of projects that can build at the same time. The maximum number of parallel projects is set automatically to the number of CPUs of your computer to optimize the build process. The maximum is 32.
Only Build Start-up Projects and Dependencies on Run
When selected, pressing F5 or clicking Start on the Debug menu or Build on the Build menu only builds the start-up project and dependencies. When this option is cleared, pressing F5 builds all projects, dependencies, and solution files. By default, this option is cleared.
