Hello All!
I am using Visual Studio 2019 to create a C ++ Windows Forms Application using the appropriate extension.
I made an application that displays an empty form.
Next I want to connect the CyAPI.lib library.
But as soon as I add #include <wtypes.h> at pointed place, I have gotten many errors.
I found that the reasons for the errors lie in the file "C:\Program Files(x86)\Windows Kits\10\Include\10.0.18362.0\um\ servprov.h"
I tried to solve this but couldn't find anything other than replacing * with ^ or other ways which didn't work or I couldn't understand ones.
Help me please!

Hello,
I tried the code on my side and it built without any errors when the wtypes.h was included.
I use Windows 10 SDK version 10.0.19041.0
You can install the latest version from Visual Studios using the Tools-> Get Tools and Features-> Individual Components -> Windows 10 SDK (<latest version>)
Thanks,
Yatheesh
