声明PostMessage函数的时候（其实很多很多API函数都是这样），有两种版本：A结尾的是ANSI版本，W结尾的是Unicode版本。一般用A结尾的。你声明的时候不是也写了：Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long么。可见PostMessage是我们为了方便起的名字，PostMessageA才是人家的原名。

可以简化成这样Public Declare Function PostMessageA Lib "user32" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

Public Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
PostMessageA是api函数，PostMessage不是。
PostMessage只是PostMessageA在本程序中的别称。换句话说，你可以把PostMessage改成其他名称。
