Just include windows h instead of stdfax or create a clean project without template

You can fix this problem by adding    ProjectDir    or wherever the stdafx h is  to list of directories under Project- Properties- Configuration Properties- C C  - General- Additional Include Directories

Just running through a Visual Studio Code tutorial and came across a similiar issue   Replace  include  stdafx h  with  include  pch h  which is the updated name for the precompiled headers

You have to properly understand what is a  stdafx h   aka precompiled header  Other questions or Wikipedia will answer that  In many cases a precompiled header can be avoided  especially if your project is small and with few dependencies  In your case  as you probably started from a template project  it was used to include Windows h only for the  TCHAR macro   Then  precompiled header is usually a per-project file in Visual Studio world  so    Ensure you have the file  stdafx h  in your project  If you don t  e g  you removed it  just create a new temporary project and copy the default one from there  Change the  include  lt stdafx h gt  to  include  stdafx h   It is supposed to be a project local file  not to be resolved in include directories    Secondly  it s inadvisable to include the precompiled header in your own headers  to not clutter namespace of other source that can use your code as a library  so completely remove its inclusion in vector h

Add  include  afxwin h  in your source file  It will solve your issue

There are two solutions for it   Solution number one  1 Recreate the project  While creating a project ensure that precompiled header is checked Application settings        Do not check empty project   Solution Number two  1 Create stdafx h and stdafx cpp in your project 2 Right click on project -  properties -  C C   -  Precompiled Headers 3 select precompiled header to create  Yc  4 Rebuild the solution  Drop me a message if you encounter any issue
