本来就没有全部的,任何人都可以自己定义消息,而且没有义务通知别人消息的参数的含义。Windows里面一些消息的值和参数在Windows SDK里面有说明。

这些消息的文档都在Windows SDK里面。比如你提到的这个消息的文档里面就指出WM_SETTEXT的值是12,第一个参数没有被使用,第二个参数是字符串。

不知道你说的check指令是什么。Windows有一个checkbox通用控件,不过这个控件有很多消息可以更改Check状态(比如鼠标点击,按空格键等等)。其他控件也有包含check的,比如ListView,TreeView等等。
消息都是窗口过程处理的,在问一个消息的含义的时候你应该先指名窗口类别。
