IInitiateWinSATAssessment：：InitiateFormalAssessment 方法 (winsatcominterfacei.h)
[IInitiateWinSATAssessment：：InitiateFormalAssessment 可能会在Windows 8.1后更改或不可用。]
启动正式评估。
语法
HRESULT InitiateFormalAssessment(
[in, optional] IWinSATInitiateEvents *pCallbacks,
[in, optional] HWND callerHwnd
);
参数
[in, optional] pCallbacks
实现的 IWinSATInitiateEvents 接口，用于在评估完成或取得进展时接收通知。 如果不想接收通知，可以为 NULL 。
[in, optional] callerHwnd
客户端的窗口句柄。 句柄用于居中 WinSAT 对话框。 如果 为 NULL，则对话框在桌面上居中。
返回值
此方法可以返回其中一个值。
下表列出了此方法返回的一些 HRESULT 值。
| 返回代码/值 | 说明 |
|---|---|
|
WinSAT 已成功启动。 若要确定评估是否成功运行，请实现 IWinSATInitiateEvents：：WinSATComplete 方法并检查 hresult 参数的值。 |
|
找不到预期位置的 WinSAT 程序。 |
注解
通常运行正式评估来评估计算机的所有子组件，而临时评估会评估计算机的一个子组件。 若要运行临时评估，请调用 IInitiateWinSATAssessment：：InitiateAssessment 方法。
若要获取正式评估的结果，请使用 IQueryRecentWinSATAssessment 接口。
如果从 Windows 应用程序调用此函数，请实现 IWinSATInitiateEvents 接口，以便在评估完成后显示进度信息并接收通知。 对于 Windows 控制台应用程序，不需要显示进度，因为 WinSAT 会将进度信息写入控制台窗口。
请注意，WinSAT 需要管理员权限才能运行。 如果用户没有管理员权限，WinSAT 将显示一个要求提供凭据的对话框。
