一个进程给另一个进程交换数据,如果信息量少,可以使用消息所带的参数wParam和lParam.
如果数据大的话(例如100字节),除了剪贴板,DDE,文件映射之外还有什么方法吗?
我用过GlobalAlloc,无效.

;Thread-local (or thread) variables are used in multithreaded applications.
A thread-local variable is like a global variable, except that each thread
of execution gets its own private copy of the variable, which cannot be
accessed from other threads. Thread-local variables are declared with threadvar
instead of var. For example,

threadvar X: Integer;

如果是两个应用程序，可以在一个程序中为另一个创建 COM Server,
通过接口直接调用过程.

我想利用剪贴板的原理，建立一块共享内存。
