VB6只有Beep，没有APIBeep吧？

这里用APIBeep，也能运行：

MSDN和网上只能查到Beep函数：

APIBeep和Beep都能运行，神了。

Beep示例：

Private Declare Function Beep Lib "kernel32" Alias "Beep" (ByVal dwFreq As Long, ByVal dwDuration As Long) As Long

Private Sub Form_Load()
Beep 2000, 100
End Sub

APIBeep示例：

Private Declare Function APIBeep Lib "kernel32" Alias "Beep" (ByVal dwFreq As Long, ByVal dwDuration As Long) As Long

Private Sub Form_Load()
APIBeep 2000, 100
End Sub

这到底是什么情况？

明白了，Function Beep Lib "kernel32" 里的这个Beep是可以自定义的。

VB里本没有APIBeep，可以任意定义。

定义成这样都行，例：

Private Declare Function abcdefghijklmn Lib "kernel32" Alias "Beep" (ByVal dwFreq As Long, ByVal dwDuration As Long) As Long

Private Sub Form_Load()
abcdefghijklmn 2000, 100
End Sub
