object.IsReady

object 总是一个 Drive 对象。


说明
----
对于可删除媒体驱动器和 CD-ROM 驱动器来说，仅当插入了适当的媒体，并已准备好供访问时，IsReady 才返回 True。

下面的代码举例说明了 IsReady 属性的用法：

Sub ShowDriveInfo(drvpath)
    Dim fs, d, s, t
    Set fs = CreateObject("Scripting.FileSystemObject")
    Set d = fs.GetDrive(drvpath)
    Select Case d.DriveType
        Case 0: t = "Unknown"
        Case 1: t = "Removable"
        Case 2: t = "Fixed"
        Case 3: t = "Network"
        Case 4: t = "CD-ROM"
        Case 5: t = "RAM Disk"
    End Select
    s = "Drive " & d.DriveLetter & ": - " & t
    If d.IsReady Then 
        s = s & vbCrLf & "Drive is Ready."
    Else
        s = s & vbCrLf & "Drive is not Ready."
    End If
    MsgBox s
End Sub
