These analyses showed that outbreak contributing factors were more often identified when an outbreak etiologic agent had been identified, when the outbreak establishment prepared all meals on location and served more than 150 meals a day, when investigators contacted the establishment to schedule the environmental assessment within a day of the establishment being linked with an outbreak, and when multiple establishment visits were made to complete the environmental assessment. To address these gaps, we analyzed data from 297 single-setting outbreaks reported to CDC's new outbreak surveillance system, which collects data from the environmental health component of outbreak investigations (often called environmental assessments), to identify outbreak characteristics associated with contributing factor identification. However, only about half of foodborne illness outbreaks reported to the United States' Centers for Disease Control and Prevention (CDC) have an identified contributing factor, and data on outbreak characteristics that promote contributing factor identification are limited.
You may want to take a look at the DirectX Tool Kit tutorials.Information on the factors that cause or amplify foodborne illness outbreaks (contributing factors), such as ill workers or cross-contamination of food by workers, is critical to outbreak prevention. For XInput, you can use the basic XInput 9.1.0 which is built-in to Windows 7. See Microsoft Docs.įor XAudio2 on Windows 7 SP1, use the XAudio2Redist instead of the legacy DirectX SDK. That said, if your learning materials still reference legacy stuff like D3DX11, you can install it but beware there are some special setup details. You do not need the legacy DirectX SDK at all. VS 2019 comes with the Windows 10 SDK which includes everything you need for basic Direct3D 11 system headers and libraries. Officially Windows 7 RTM is not supported. VS 2019 can support targeting Windows 7 Service Pack 1 for Win32 desktop development. For the details on handling DirectX 11.0, see this blog post. My Win32 templates assume you have DirectX 11.1 these days. Most any Windows 7 system that's updated from Windows Update should have it. Basically this means you won't get D3D_FEATURE_LEVEL_11_1. Windows 7 can support DirectX 11.1 "software features" but not "hardware features" with KB2670838. I maintain a number of similar templates for UWP and Win32 for DirectX 11 & DirectX 12 on GitHub. As noted by Simon in the comments, the "DirectX" templates built-in to VS 2019 are for Universal Windows Platform (UWP) apps only which requires Windows 10.
