Hi,
I''m using the following example for this:
http://www.yoda.arachsys.com/csharp/...ation.instance
which works perfectly on Vista, but not on XP...
Doesn''t throw any errors, but multiple launches of the app are not
prevented.
Is there another solution?
Any assistance gratefully received.

Mark，
此前一个帖子指出：

基本上，你要去使用Microsoft.VisualBasic命名空间中的WindowsFormsApplicationBase类。

Mark,
This previous thread indicates how:

Basically, you are going to use the WindowsFormsApplicationBase class in
the Microsoft.VisualBasic namespace.

哎哟！在C＃应用程序中使用Microsoft.VisualBasic命名空间......？
嗯 - 好吧，我想我将不得不停止对此如此肛门！
好奇Jon的代码在Vista上完美运行，但是...

Ouch! Use the Microsoft.VisualBasic namespace in a C# app...?
Hmm - OK, I guess I''ll have to stop being so anal about that!
Curious that Jon''s code works perfectly on Vista, though...

您是否看到有关它是本地互斥的评论？您是在单个用户会话中测试多次启动应用程序，还是在用户会话中测试
（例如终端服务或快速用户切换）？
如果是后者，你需要使互斥量全局化。如果是前者，那么
奇怪的是它不起作用......也许这是一个权限问题。

Hi,
Did you see the comment about it being a local mutex? Are you testing
multiple launches of the application within a single user session, or
across user sessions (e.g. terminal services or fast user switching)?
If the latter, you''ll need to make the mutex global. If the former, then
it''s strange that it doesn''t work... Perhaps it''s a permissions issue.
