Does anybody has experience of accessing a Virtual Server (COM) through

推荐答案
Clas，
你为什么要打电话给CoInitializeSecurity？由于您正在调用COM
对象，您是否将ASPCompat属性设置为true？此外，
对象是否执行需要文件或注册表访问的任何内容？
您可能需要冒充有权使用
访问虚拟服务器。
希望这会有所帮助。

Clas,
Why are you calling CoInitializeSecurity? Since you are calling a COM
object, are you setting the ASPCompat attribute to true? Also, does the
object do anything that requires file or registry access?
Chances are you will have to impersonate a user that has the rights to
access virtual server.
Hope this helps.

嗨尼古拉斯：
其实，在在这种情况下，Girish指出的文档说：
多线程公寓模型应该用于应用程序
使用虚拟服务器COM接口。使用具有Virtual Server COM接口的单线程
公寓模型可以显着影响Virtual Server系统的性能。
在这种情况下OP不想设置aspcompat =" true"

Hi Nicholas:
Actually, in this case the documentation Girish pointed to says:
"The multithreaded apartment model should be used for applications
using the Virtual Server COM interfaces. Using the single-threaded
apartment model with the Virtual Server COM interface can
significantly affect the Virtual Server system''s performance."
In which case the OP would not want to set aspcompat="true".
