回答（1）：

要么写在一行里，要么加换行符，像这样：
Private Declare Function CDdoor Lib "winmm.dll" Alias "mciSendStringA" () _
(Byval lpstrCommand as String,byval lpstrReturnString as String,byval uReturnlength as long,Byval hwndCallback as Long) As Long

回答（2）：

把第一行的()去掉，换成“ _”符号，_ 符号前加个空格才能换行继续写

回答（3）：

Private Declare Function CDdoor Lib "winmm.dll" Alias "mciSendStringA" _
(ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnlength As Long, ByVal hwndCallback As Long) As Long
