IsReady

IsReady 属性 描述如果指定的驱动器已准备好，返回 True；否则返回 False。语法object.IsReadyobject 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 sEnd Sub
