Answer 1

Besides aphostrophes you may need to disable precompiler headers in project properties.

They are turned on by default in VS2012. If you are not familiar with precompiled headers turn them off.

1. Right click on project (not solution)
2. Click properties.
3. Expand "Configuration properties"
4. Expand "C/C++"
5. Choose "Precompiled headers"
6. Set "Precompiled header" to "Not Using Precompiled Headers"
