How do I write a function that accepts any type of standard container?

Raymond ChenJune 19, 2019Jun 19, 201906/19/19

There's the standard way, and then there's the generous way.

Pass something else that is easy to copy.

Why does SetFocus fail without telling me why?

If you're going to replace part of the operating system, you have to replace the side effects, too.

What should you do if somebody passes a null pointer for a parameter that should never be null? What if it’s a Windows Runtime class?

They messed up, so make them suffer the consequences, but make the consequences diagnosable.

If you can use GUIDs to reference files, why not use them to remember “recently used” files so they can survive renames and moves?

Raymond ChenJune 12, 2019Jun 12, 201906/12/19

Because the file that you think is the same file may not actually be the same file.

How can I determine in a C++ header file whether C++/CX is enabled? How about C++/WinRT?

For conditionally enabling features, say.

The Resource Compiler defaults to CP_ACP, even in the face of subtle hints that the file is UTF-8

Raymond ChenJune 7, 2019Jun 7, 201906/7/19

Subtlety is not its strong point.

Why does my C++/WinRT project get errors of the form “Unresolved external symbol void* __cdecl winrt_make_YourNamespace_YourClass(void)“?

Raymond ChenJune 6, 2019Jun 6, 201906/6/19

You enabled optimizations, but there's some extra bookkeeping to support those optimizations.

Why does my C++/WinRT project get errors of the form ‘winrt::impl::produce<D, I>‘: cannot instantiate abstract class, missing method GetBindingConnector

The header file requirement was always present, but you often got away with omitting it. Not so much any more.

I called AdjustTokenPrivileges, but I was still told that a necessary privilege was not held

Raymond ChenMay 31, 2019May 31, 201905/31/19

Which token did you adjust?
