Vbscript to search and replace numbers

I tried a script similar to this, however it does not work, it is not replacing any of the numbers
I want replaced.
Const ForReading = 1
Const ForWriting = 2

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\Script\file.CSV", ForReading)

strText = objFile.ReadAll
objFile.Close
strNewText = Replace(strText, "1223234343434 ", "102343433434334 ")

Set objFile = objFSO.OpenTextFile("C:\Script\file.CSV", ForWriting)
objFile.WriteLine strNewText
objFile.Close

What does blind link comments refer to?

Add a debugging line in to display the contents of strText to ensure it's what you expect.  Sometimes there can be file encoding screwing this sort of thing up.

Try adding the Tristate value for Unicode when opening the file if strText looks wrong:

ie
Const ForReading = 1
Const FSO_Unicode = -1
Set objFile = objFSO.OpenTextFile("C:\Script\file.CSV", ForReading, False, FSO_Unicode)
strText = objFile.ReadAll

Also, remove any "On Error Resume Next" you may be using in case an error is being thrown.

Yes, but rather than write it out in full or paste someone's work I sent the link which was subsequently deleted as a "blind comment".
I didn't know this wasn't allowed (my fault).

I want to give QPR a chance to provide a written script which works, so that i can give QPR the points instead, since we were not aware we could not include blind links.

That's ok just the close the question :)
I wasn't aware of the policy but am now.
Next time I'll know to provide the important part from the link and attribute the original author. Glad you got it working

It works.
