[scripting] bat file will only run one time

[David Landry]

Hi All,

I will admit up front, my script write abilities are slim. I have this script 
that I found to insert a new line of text into an .ini file and it works 
perfectly .... But for just one time. During my testing I removed the inserted 
line and text and then reran the script. Only this time it didn't do anything. 
Nothing got inserted. After rerunning this a dozen times or so I can't figure 
out why.

I tried this on a Windows 10 and a Windows 7 system with same behavior. It ran 
only once on each system.

set objWS = CreateObject("Wscript.Shell")
Set fsob=CreateObject("Scripting.FileSystemObject")

strNewLine = "AdminPassword=@dm1n1$trat0r!"
strFileName = "C:\test\script\CustomSettings.ini" ' for example c:\textfile.txt

Const FOR_READING = 1
Const FOR_WRITING = 2
strCheckForString = UCase("SkipAdminPassword=YES")
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objTS = objFS.OpenTextFile(strFileName, FOR_READING)
strContents = objTS.ReadAll
objTS.Close
arrLines = Split(strContents, vbNewLine)
Set objTS = objFS.OpenTextFile(strFileName, FOR_WRITING)
For Each strLine In arrLines
  If (Left(UCase(LTrim(strLine)),Len(strCheckForString)) = strCheckForString) 
Then
    objTS.WriteLine strLine
    objTS.WriteLine strNewLine
  else
    objTS.WriteLine strLine
  End If

Can anyone explain this to me? What needs to be changed?

Thanks in advance
