Sometimes when working on projects that people have posted online, I have to frantically modify my own property sheets to match theirs in order for my project to work (things like: MTd, linker stuff, Unicode/Multibyte settings).
I was wondering if I could just export a property sheet in Visual Studio for later use instead of creating one from scratch.
Not if you use their project file, its settings are "last" and override anything you'd set in a project property sheet.
Nothing that you couldn't fix with a text editor btw, open the .vcproj or .vcxproj file with, say, Notepad to see how you could delete settings so a property sheet can work. Or copy/paste settings from your own project file.
