IInitiateWinSATAssessment：：InitiateAssessment 方法 (winsatcominterfacei.h)
[IInitiateWinSATAssessment：：InitiateAssessment 可能会在Windows 8.1后更改或不可用。]
启动临时评估。
语法
HRESULT InitiateAssessment(
[in] LPCWSTR cmdLine,
[in, optional] IWinSATInitiateEvents *pCallbacks,
[in, optional] HWND callerHwnd
);
参数
[in] cmdLine
要传递给 WinSAT 的命令行参数。 命令行不能为空。 有关命令行用法，请参阅 Microsoft TechNet 上的 WinSAT 命令参考 。
[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。 |
|
命令行不能为空;必须提供命令行参数。 |
|
命令行太长。 最大长度为 30，720 字节。 |
|
找不到预期位置的 WinSAT 程序。 |
注解
通常运行临时评估来评估计算机的一个子组件，而正式评估会评估计算机的所有子组件。 若要运行正式评估，请调用 IInitiateWinSATAssessment：：InitiateFormalAssessment 方法。
临时评估不会保存在 WinSAT 数据存储中;数据存储中仅保存正式评估， (无法使用 IQueryRecentWinSATAssessment 接口查询结果) 。 若要获取临时评估的结果，请包含 –xml FileName 参数，这将将结果保存到 XML 文件，稍后可以分析该文件。
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。
