Some modern casting issues.. CBitmapPixelAccess::setPosition and itmapPixelAccess::operator++

[GeorgeAAbraham1]

cbitmap.h CBitmapPixelAccess::setPosition and itmapPixelAccess::operator++ Gives compiler error : currentPos = address + y bytesPerRow; Expectation, something like.. : currentPos = address + static_cast<__int64>(y) bytesPerRow;

Can you please add the complete compiler output and the compiler version when doing such a bug report. That would help enormously.

Hi

Sure..

Microsoft Visual Studio Community 2022 Version 17.2.6 VisualStudio.17.Release/17.2.6+32630.192 Microsoft .NET Framework Version 4.8.03752

Installed Version: Community

Visual C++ 2022 00482-90000-00000-AA939 Microsoft Visual C++ 2022

This is covered in the C++ 17 book.. as a standard change.. it's not a bug.
