消息中有什么？



是否觉得一个消息记录中的信息像希腊语一样？如果是这样，那么看一看下面的解释：



hwnd 32位的窗口句柄。窗口可以是任何类型的屏幕对象，因为Win32能够维护大多数可视对象的句柄(窗口、对话框、按钮、编辑框等)。



message 用于区别其他消息的常量值，这些常量可以是Windows单元中预定义的常量，也可以是自定义的常量。



wParam 通常是一个与消息有关的常量值，也可能是窗口或控件的句柄。



lParam 通常是一个指向内存中数据的指针。由于W P a r a m、l P a r a m和P o i n t e r都是3 2位的，因此，它们之间可以相互转换。-had any news? Think that the news of the information in the record as Greek? If this is the case, then look at the following explanation : hwnd 32 of the window handle. Window can be any type of screen, because most of Win32 to maintain a handle visual objects (windows, dialog boxes, buttons, edit box, etc.). Message used to distinguish between other sources of regular money, These constants can be Windows modules predefined constants, it can also be a self-defined constants. WParam is usually a source with the regular money, it might be the window handle or control. LParam is usually a memory data at the target. As a W P a r m, l P a r m and a P i n o t r e are three-two, therefore, They could change.
