编程是在学习中不断进步，这个不假，这两天一直在折腾VB脚本编程，原因可以追溯到我关于VB脚本编程的第一篇文章简单的VB小脚本之——文件处理脚本，里面提到了上帝，额不，是我的客户提到的一个简单的小要求，就是希望我写个VB的脚本来处理文件，于是我就现学现用了，完成了1.0的版本。客户就是上帝，上帝说要写VB脚本，于是就有了VB脚本。这不，提交了之后，上帝说，改进一下，在命令行里实现调用，并且传参数，比如，xx.vbs -normal 22.log 66 Eric.Tang这个用来把22.log文件中的“66”字符串儿替换为“Eric.Tang”，同时呢还要加入正则表达式的验证，比如xx.vbs -regex 22.log “<.*>" Eric.Tang这个用来把22.log文件中<>括号中的内容替换为Eric.Tang，折腾了大半天之后就有了以下的VB脚本2.0版本，内容源码如下：

currentPath=CreateObject("Scripting.FileSystemObject").GetFolder(".").Path
Set objArgs = WScript.Arguments
If objArgs.count < 4 Then
	MsgBox("Missing parameters!")
Else
Set objFSO = CreateObject("Scripting.FileSystemObject")
	If objFSO.FileExists(currentPath & "\" & objArgs(1)) Then 'if file exists or not
		Set objFile=objFSO.OpenTextFile(currentPath & "\" & objArgs(1))
		str=objFile.ReadAll  'get content of the file
		objFile.close
		If objArgs(0) = "-normal" Then
			oldStr=objArgs(2) 'the old string that you want to find
			newStr=objArgs(3) 'the new string that you want to replace with
			If oldStr <> "" Then
				str=replace(str,oldStr,newStr)
				tmpArray=split(objArgs(1),".")
				Set newFile=objFSO.CreateTextFile(currentPath & "\" & tmpArray(0) & "_Normal" & ".txt")
				newFile.write(str)
				newFile.close
				If objFSO.FileExists(currentPath & "\" & tmpArray(0) & "_Normal" & ".txt") Then
					MsgBox("Normal handled file has been created successfully! Please check " & currentPath & "\" & tmpArray(0) & "_Normal" & ".txt")
				Else
					MsgBox("Errors happened while Normal-Handling!")
				End If
			End If
		ElseIf objArgs(0) = "-regex" Then
			Set regEx=New RegExp 'create a regex
			patern=objArgs(2)
			regEx.Pattern=patern
			regEx.IgnoreCase = True 'ingnore the Upper/Lower case
			regEx.Global = True     'if can be used Globally
			If str <> "" Then
				Set Matches = regEx.Execute(str)   'excute search
				If Matches.count <> 0 Then
					For Each Match in Matches
						str=replace(str,Match.Value,objArgs(3))
					Next
					tmpArray=split(objArgs(1),".")
					Set newFile=objFSO.CreateTextFile(currentPath & "\" & tmpArray(0) & "_Regex" & ".txt")
					newFile.write(str)
					newFile.close
					If objFSO.FileExists(currentPath & "\" & tmpArray(0) & "_Regex" & ".txt") Then
						MsgBox("Regex handled file has been created successfully! Please check " & currentPath & "\" & tmpArray(0) & "_Regex" & ".txt")
					Else
						MsgBox("Errors happened while Regex-Handling!")
					End If
				Else
					MsgBox("No matches found!")
				End If
			End If
		End If
	Else
		MsgBox("File not exist!")
	End If
End If
