represent soft reference, weak reference, and virtual reference respectively. The referencequeue class indicates the reference queue. It can be used with these three reference classes to track the collection of referenced objects by the Java Virtual Machine. The following program creates a String object, referencequeue object, and weakreference object:
// Create a strong referenceString STR = new string ("hello ");
// Create a reference queue,

The following is an example of using a named pipe in Python to implement inter-process communication.

This article I put WF on data processing operations completely to WCF processing, WF only care about the process design processing, as to the underlying data how to operate does not need to care. This reduces the degree of coupling between applications in a large program.

You can use Sendactivity to comple

? Probably not. What if the server needs load balancing? If the idea is limited to a single process, the situation will become very difficult. What's worse, what if you need to restart the server or crash the process? If this happens, all running operations will be lost.
In fact, when an operation takes several days or weeks to complete, you need a solution that is independent of the lifecycle of the operation process. This is an indisputable fact, especially for ASP. NET Web applications.
