基于Delphi的进程通信研究和应用

Research and Application of Process Communication Based on Delphi

介绍了进程与进程通信的含义、WM-COPYDATA消息传递机制的特点以及进程死锁的原因,并通过实例详细阐述了基于Delphi编写进程和进程通信的设计方法和思路,阐述了消息机制方式的调用过程和限制条件,给出了具体的解决办法。根据实际应用可以证明,采用这种技术使得系统获得了良好的效果。

Presents the definition of the process and process communication,the character of the message mechanism of WM-COPYDATA, and the reason of deadlock. Also prescribes the design methods that write the program of the process and process communication based on Delphi, with emphasis on the calling procedure and conditional restriction of message mechanism.According to the practical application,it can get good result by using the technology.
