如何判断用户是否安装消息队列。如果没有安装，就调用消息队列程序安装。

Hi ,

试试这个blog里的方法: http://blogs.msdn.com/b/johnbreakwell/archive/2008/05/14/how-to-tell-if-msmq-is-installed.aspx 

Yes. Try to load Mqrt.dll (using the LoadLibrary API).

·         For MSMQ 1.0 and 2.0, the DLL file is not present on the disk if Message Queuing is not installed and so you won't be able to load it.

·         For MSMQ 3.0, the Message Queuing binaries are always present on the disk, but trying to load Mqrt.dll fails with ERROR_DLL_INIT_FAILED if Message Queuing is not installed. 

希望有用.
