参数表
参数 类型及说明
nDrive String，包含了驱动器根目录路径的一个字串
如下用打开光盘指定的里的文件做例子:
Private Declare Function GetLogicalDriveStrings Lib "kernel32" Alias "GetLogicalDriveStringsA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long
Private Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long
Private Sub Form_Click()
Dim StrDrive As String '盘符串(A:\ C:\ D:\...)
Dim DriveID As String'盘符(如:A:\)
StrDrive = String(100, Chr$(0))'初始化盘符串
Call GetLogicalDriveStrings(100, StrDrive) '返回盘符串
Dim i As Integer
'返回光盘盘符到数组
For i = 1 To 100 Step 4 '注意这里是4
DriveID = Mid(StrDrive, i, 3)'枚举盘符
If DriveID = Chr$(0) & Chr(0) & Chr(0) Then Exit For '没有盘符,即时退出循环
If GetDriveType(DriveID) = 5 Then Call ShellPro(DriveID)
'如果枚举到的盘是CD-ROM,转到 ShellPro 子程序
