ISensLogon事件处理程序未接收事件 [英] ISensLogon Event Handler not receiving Events
问题描述
我在网上找到了一些处理ISensLogon事件的代码。我正在编写服务来记录这些事件，以监控学生每月登录的时间。每个月70个小时，他们得到一个专用工作站，他们使用共享桌面另外明智
。
在编写服务之前，我正在编写一个代码来查看我的程序是否获得了这些事件并能够将它们写入磁盘。我在网上找到的代码编译没有错误，每个函数调用都被跟踪，返回都是S_OK但是当我锁定我的工作站
为屏幕保护程序启动/停止时，事件不会记录在文件中。 / p>
我找到了两个示例代码 对于ISensNetwork和一个ISensLogon，它们都是相似的，所以我采用并混合它们。
任何想法代码都没有得到事件。如果我可以使这个工作，我可以继续使这个服务例程
Thanx

你有没有得到这个工作？我遇到了同样的问题。
你有没有试过看看其他ISens对象是否像ISensNetwork一样看看它们是否适合你
I found some code on the Net to handle ISensLogon Events. I am in the processes of writing a service to record these events to monitor how long students remain login in on a monthly bases. 70 hours per month and they get a dedicated workstation other wise they use a shared desktop.
Before writing the service I am working an code to see if my program gets the events and is able to write them to disk. The code I found on the net compiles without errors, each function call is traced and the returns are all S_OK but when I Lock my workstation for the screen saver starts/stops, the event is not recorded in a file.
I found two sample codes for ISensNetwork and one for ISensLogon which were every similar so I adopted and mix both.
Any idea why the code does not get the events. If I can get this working I can proceed to making this a Service routine
Thanx

Did you ever get this to work? i'm having the same problem.
Did you ever try and see if the other ISens objects like ISensNetwork to see if they worked for you?
