这两天一直在研究脚本中的场景恢复，以前一直想把场景恢复放到外面做统一的处理。所以就想通过函数去解决，结果用err.number和err.description获取不到异常run error提示.请教了前辈，前辈说我这样是处理不好的，没有办法统一处理，还是放到脚本中。自己又折腾了一天，最后还是决定放弃了，在脚本中做场景恢复，觉得也蛮有效果的。函数如下：
' 编写日期: 2013-7-10

'============================================================================
'用于恢复场景控制。
Function RecoveryFunctions(Object, Method, Arguments, retVal)
'有错误发生时，对Desktop进行截图并保存

'定义保存截图的路径
strDesktopFolder = "D:/TestData/测试截图/"
'创建文件对象
Set bjFSO = CreateObject("Scripting.FileSystemObject")
'判断文件是否存在，不存在创建一个文件
If objFSO.FolderExists(strDesktopFolder) Then
Set bjFolder = objFSO.GetFolder(strDesktopFolder)
Else
Set bjFolder = objFSO.CreateFolder(strDesktopFolder)
End If
'确定保存文件的名称
tmpTime=Time()
t=Split(tmpTime,":")
If Len(t(0))<2 Then
t(0) = "0" & t(0)

tmpTime=t(0) & t(1) & t(2)

tmpYear = CStr(Year(tmpDate))
tmpMonth = CStr(Month(tmpDate))
