cannot open source file "afxwin.h"/"afxext.h"/"afxdisp.h"/"afxdtctl.h"/"afxcmn.h"/afxdisp.h etc

Question

I try to ran a previous written MFC c++ code on my visual studio 2015 MFC with multitype MFC library installed.

However, I still have 12 errors here regarding missing function:

IntelliSense: cannot open source file "afxwin.h" C1083 Cannot open include file: 'afxwin.h': No such file or directory cannot open source file "afxext.h"/"afxdisp.h"/"afxdtctl.h"/"afxcmn.h"/afxdisp.h etc....

Where can I get these head files?

Again, my set up is:

VIsual studio 2015 ultimate MFC Multibyte MFC library installed Windows 8 - 64 bit machine

Thanks!

Answer 1

I just fixed a similar problem. Here's how you can resolve this.

1. Go to your control panel
2. Navigate to uninstall/change a program.
3. Scroll down until you see your visual studio installation
4. Click change
5. Once the window pops up, click "Modify"
6. Under Programming Languages -> Visual C++ Make sure "Microsoft Foundation Classes for C++" is checked. If it isn't select it and click update.

For VS2019 the above solutions didn't worked for me. I had to go to "Installer -> Individual Components -> " and install the following to solve the issue:

• "MSVC v141 – VS 2017 C++ x64/x86 build tools (v14.16)"
• "C++ MFC for v141 build tools (x86 & x64)"
• "C++ ATL for v141 build tools (x86 & x64)"
