我们有一个应用程序，该应用程序要么在主线程或其他线程中运行某些com托管连接点接口以获取事件。
到Windows 10 SP 1903，它确实有效。
但是在" 1903 Update"中测试应用程序时 IConnectionPoint->Advise()当代码在与启动线程不同的线程中运行时，使用Connect_e_cannotConnect失败 - novers server询问了很多我不支持的接口，我只支持iunknown，idispatch和事件界面，因为。
当整个事物在非sta主线程中运行时，会查询很多接口，少于＆lt;1903年，1903年是：

咨询((然后放弃并返回上述错误代码。因此，我不能在与应用程序的主STA线程不同的线程中创建事件沉入。
更明确地，我们有一个关系管理器应用程序，该应用程序想在其他线程中显示非模式对话框，即
- 该应用程序创建了一个新线程，
- 托管然后执行的脚本，
- 脚本调用应用程序的方法(是标准的OLE服务器(，该方法创建了管理对话框窗口的OLE控件(使用CocreateinStance等([我假设在主STA线程中创建]
- 然后脚本连接脚本线程中的控件(使用exhbise((等(，以便对话框控件可以使用脚本主机中的对象触发事件
因此，如果要做划定，我现在的猜测是它是对话框控件内部的，必须将我通过我传递给建议的指针((，至少这就是我在www深处阅读的内容。由于我们在这里不做任何事情，因此使用标准的卫生员，通过bamase！cstdmarshal：createStub((，似乎不再成功了。当我被问到一个接口时的堆栈(上(为

我将其解释为试图设置默认编组的Combase，以及在1903年更新中失败的某个地方。所以我的问题是，为什么会失败，当我都建议((时，我的班级需要什么？
或者是在STA主线程中创建服务器(可连接对象(，并且必须以某种方式更改以支持编组到新线程的事件接收器call depandise((？
在以前的版本中找到了几乎相同的堆栈，但成功。
啊，好吧 - 使用vs 2019和_merge_proxystub(以及对话框对象中的某些调整(可以做到了……标准代理也许是错误的？哎呀，我很高兴它有效。
@Raymond：感谢您的回答 - 这是您带领我的正确曲目！
