Question

尝试使用我的C＃代码中的IActiveScriptProfilerControl::StartProfiling，我创建了这个接口定义：

[ComImport]
[Guid(@"784b5ff0-69b0-47d1-a7dc-2518f4230e90")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
internal interface IActiveScriptProfilerControl
{
    void StartProfiling(
        ref Guid clsidProfilerObject, 
        ProfilerEventMask eventMask, 
        uint dwContext);

    // ...
}

我相信它已被正确翻译为.NET。

原始的第一个参数定义为

[in] REFCLSID clsidProfilerObject

有了这些定义：

typedef GUID CLSID;
typedef CLSID *REFCLSID;

我还可以创建一个微软JQueryScriptEngine对象的实例并查询IActiveScriptProfilerControl。

我目前失败的是如何告诉StartProfiling函数使用我的IActiveScriptProfilerCallback派生对象。

我的问题：

如何通过调用IActiveScriptProfilerControl::StartProfiling将我自己的探查器回调类与活动脚本探查器控件接口连接？

理想情况下，我很乐意这样做，而需要RegAsm我的班级。

更新1：

我已将接口定义的第一个参数更改为：

[ComImport]
[Guid(@"784b5ff0-69b0-47d1-a7dc-2518f4230e90")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
internal interface IActiveScriptProfilerControl
{
    void StartProfiling(
        IActiveScriptProfilerCallback clsidProfilerObject, // <-- changed.
        ProfilerEventMask eventMask, 
        uint dwContext);

    // ...
}

并尝试通过传递我的IActiveScriptProfilerCallback派生类的实例来调用此函数。

仍然，我收到错误：

未注册的类（HRESULT异常：0x80040154（REGDB_E_CLASSNOTREG））

Answer 1

（在搜索类似错误时来自我未来的自我更新）

我已经设法通过monitoring the registry解决了这个问题，无论是对我的程序集进行Regasm.exe调用，还是监视分析器在调用StartProfiling时请求的键。< / p>

这些密钥是HKEY_CLASSES_ROOT：

所必需的

对于JScript，

Another suggestion也要添加：

[HKEY_CURRENT_USER \环境]
“JS_PROFILER”= “{1C406FBA-59EF-4FB2-938C-C1DA182D5914}”

由于我希望我的程序在没有管理权限的情况下运行，我创建了一个类来创建上面的密钥HKEY_CURRENT_USER，这也可以。

2018年7月更新

在Visual Studio 2017中直接运行时，我的开发机器再次出现了初始错误：

未注册的类（HRESULT异常：0x80040154（REGDB_E_CLASSNOTREG））

经过一番尝试和错误，我发现这是因为我configured my Visual Studio to always run as an administrator。

当从这个上下文开始时，某种程度似乎出错了。我还是不知道到底是什么。

解决方法是直接从Windows文件资源管理器启动我的可执行文件，而不是从Visual Studio中启动。

另一种可能的解决方案（我没试过）应该是不以管理员身份运行Visual Studio。

作为IActiveScriptProfilerControl.StartProfiling的第一个参数传递什么？
