For visual studio 2017 community
1.
bug: #include "stdio.h"
Go in setup ("C:\Program Files (x86)\Microsoft Visual Studio\Installer\vs_installer.exe")
In second tab, add MFC support
Change include folders path in project:
C:\Program Files (x86)\Windows Kits\10\Include\10.0.14393.0\ucrt;C:\Program Files %28x86%29\Windows Kits\10\Lib\10.0.14393.0\ucrt\x86;$(IncludePath)
Download and install the windows 10 sdk
https://dev.windows.com/en-US/downloads/windows-10-sdk
3.
ucrtd.lib bug
libraries include path:
C:\Program Files (x86)\Windows Kits\10\Lib\10.0.14393.0\ucrt\x86
2017-01-22
Configured to compile as Release
(check comment in code: Troubleshooting)
added include "windows.h" for innerhtml to work
2017-12-20
Events stopped working :(
After a reboot, it worked again
So maybe i need to free some event before closing internet explorer
2017-12-19
Corected management of left menu to exit any input form
Passed the vector as pointers, not global variables anymore
-----
This is CPP using internet explorer as an interface
Tested in windows 10
Requis:
Visual studio 2013
Warning:
not optimized at all, no release of variables (i will add later)
