#include <ScopedButtonDisabler.hpp>

This is a simple header-only RAII-style class that disable a button in a scope. When you attach a Click handler of a button and open a FilePicker, when user click fast enough, it will have 2 FilePicker opened at the same time, which is a source of logical bugs.

winrt::Windows::Storage::Pickers::FileOpenPicker picker;
picker.FileTypeFilter().Append(L"*");
auto file = co_await picker.PickSingleFileAsync();

With ScopedButtonDisabler, it will disable the button inside this handler, preventing any logical bugs that might happens.

ScopedButtonDisabler disabler{ sender };
winrt::Windows::Storage::Pickers::FileOpenPicker picker;
picker.FileTypeFilter().Append(L"*");
auto file = co_await picker.PickSingleFileAsync();
