1.进程间的数据交换。 考虑 WM_SETTEXT 消息的实现，这个消息将lParam这个参数指向的字符串，设置为窗口的标题，我们可以在不同的进程中发送这个消息。那么这个消息如何实现呢？ 考虑进程1中的字符串 LPCTSTR str = TEXT("Hello,World")，我们要把该字符串发送到进程2中该如何去做。我们知道每一个Win32进程都有其私有的进程地址空间，这些地址空间是虚拟的，所以同一个地址在不同的进程中起实际指向的物理内存是不同的，对于变量str，它实际是进程1中的一个虚拟地址，所以我们
为什么 HANDLE 返回值不同?
开发笔记

如果你注意各种返回 HANDLE 值的函数,你会发现它们有些返回 NULL(如CreateThread)而有些则返回 INVALID_HANDLE_VALUE(如CreateFile).你不得不查询文档找出每种函数在失败时返回什么.为什么返回值不一致?正如你所怀疑的那种,是历史原因.这些值是用于兼容16位 Windows.16位函数 OpengFile, _lopen 和 _lcreate 返回-1在失败的时候.因此32位 CreateFile 函数返回 INVALID_HANDLE_VALUE 以便于从
