COM+运行时信息

[Alwin_Lee]

当COM+运行时，如果我想在服务器端得到一些信息，
如：当前有多少客户使用服务器组件，每个客户的
名字，连接时间等等，应该使用哪些函数，怎么做？
谢谢！

client's name, role membership

GetCallSecurityContext

============================================
connection time

use IComObjectEvents gathers method call time, plus the security context information, you can get the component usage statistics by some specific users.

可否再详细点，最好是能有几条语句。

ok, here is some code snippet. Basically you can subscribe IComObjectEvents event interface, which can give you information about a method call/method return, etc.

besides, you can use ISecurityCallContext checking role member ship

ISecurityCallContext* pscc;
hr = ::CoGetCallContext(IID_ISecurityCallContext, (void**)&pscc);
if(hr == S_OK)
{
VARIANT_BOOL bInRole;
hr = pscc->IsCallerInRole(L"xxxxx",&bInRole);

if(hr == S_OK)
{
pvResult->boolVal = bInRole;
}
pscc->Release();
}

use ISecurityIdentityColl to check account information
