PostMessage与PostMessageA的区别
的有关信息介绍如下: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。
