I am getting the error when I try to
Use multithreading in my app's
Cpp file but not in the header/h file

Your responses suggest that you are at an early stage of learning C++. This has nothing to do with multi-threading, and everything to do with the fact that you are trying to refer to an external library, and you have not included it in your project. Your comments about .h and .cpp files suggest that you should spend some time with your study guides to understand what the purpose of each file is.

LNK2019: Unresolved external symbol 'symbol' referenced in function 'function' - which means that you are referring to some external class or function that has not been included in your project. Since you did not post the entire message it is impossible to guess what reference is causing the problem.

LNK1120 merely gives the count of unresolved externals. It suggests that you have failed to include some libraries in your project; check your settings.
