关于API函数别名的有关问题

关于API函数别名的问题
在Modules中声明了API函数：
Declare   Function   ReadFile   Lib   "kernel32 "   Alias   "ReadFileCOM "   (ByVal   hFile   As   Long,   lpBuffer   As   Any,   ByVal   nNumberOfBytesToRead   As   Long,   lpNumberOfBytesRead   As   Long,   ByVal   lpOverlapped   As   Long)   As   Long
在Form窗体中如下调用时
        Dim   retval   As   Long
        retval   =   ReadFileCOM(ComNum,   ByVal   Buffer,   255,   RetBytes,   0)
出错，Sub   Or   Function   not   denied!请问是什么原因啊？

------解决方案--------------------
Declare Function ReadFileCOM Lib "kernel32 " Alias "ReadFile " (ByVal hFile As Long, lpBuffer As Any, ByVal nNumberOfBytesToRead As Long, lpNumberOfBytesRead As Long, ByVal lpOverlapped As Long) As Long
------解决方案--------------------
同上，顺序反了。。。
------解决方案--------------------
去掉Alias "ReadFileCOM "
只用readfile
------解决方案--------------------
别名才是真名，不要搞反了，如果说还是找不到，恐怕你的api名称有误
