Win10的Bug-资源管理器如果有搜索过再最小化时导致重新搜索问题
资源管理器如果有搜索过文件, 再查看其他路径, 再最小化时导致重新搜索
Bug跟踪
- procmon 查看文件, 触发Bug搜索, 找到文件夹列表条目, 看callstack
发现在 Windows.Storage.Search.dll - 继续跟踪找到 CDefView::_OnDelayedFilterContents
- 继续: CDefView::_SetTextFilter
4, 继续: CSearchBox::_OnEditChange - 再继续找到消息 0x402, 发送源自 CSearchBox::OnListenedPropertyChanged

从这可以看到触发的原因: 窗体在最小化时触发 OnSize, OnSize导致隐藏自动完成, 隐藏自动完成导致重新更新搜索框的值, 这样就产生了重新搜索
- 修改dll修改bug
简单可以直接修改HideSuggestions, 这个一般没用, 直接在隐藏自动完成时不更新值

修改后确认有效, 替换系统dll操作会有点麻烦
