New build warnings with Visual Studio 2022 (17.2.6) version

Ankit Chaudhari 1

Hi,

We have updated visual studio 2022 with latest version 17.2.6. Package build using cl.exe we see
lot of new warnings related to type C4191.

I referred to below Microsoft link which says below warnings are turned off by default.

https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-3-c4191?view=msvc-170

PFB sample of the same.

Warning C4191 : type cast unsafe conversion from FARPROC to XXX.

XXX VAR = NULL;
VAR = (XXX) GetProcAddress(hLib,TCRUNHNHREQUESTSFUNC)

Requesting you to please mention plans to address the same.

Hello, does this warning show up before you update your VS2022 to version 17.2.6?
Please right click on your project in solution explorer > Properties > Configuration Properties > C/C++ > General > Warning Level. What is your warning level?

Hi @Anna Xiu-MSFT ,

As per below microsoft link, This warning is of level 3.
https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-3-c4191?view=msvc-170

We are compiling c code by using visual studio command prompt and not using visual studio.

Why below type warning is getting logged with Visual Studio 2022 version 17.2.6, even though as per documentation it should be off by default.
warning C4191: 'type cast': unsafe conversion from 'FARPROC' to '<variable_name>'
https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-3-c4191?view=msvc-170

Why this warning is getting logged with VS 2022 version 17.2.6 and not with VS version 17.1.3.

-thanks,
Ankit

Hello everyone. I am currently in Asp.net core
  I'm creating a View and I'm writing Html code and suddenly it gets stuck and I have to close Visual and open it again. Now I've changed Windows and reinstalled Visual, and these errors are still there.
Do you have a solution for this, or should the visual bug be updated?
