I need to change/replace a word in a row in batch file. for example "localhost" to "AAA". Supose there are no diference to the same in *.txt however can someone help me? thanks!

I found one way to do this but there is one litte problem again. I don`t want to change all "Jim" to "James" but in one row only. who can help me with this .vbs script? thanks!

Const ForReading = 1
Const ForWriting = 2

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\Scripts\Text.txt", ForReading)

strText = objFile.ReadAll
objFile.Close
strNewText = Replace(strText, "Jim ", "James ")

Set objFile = objFSO.OpenTextFile("C:\Scripts\Text.txt", ForWriting)
objFile.WriteLine strNewText
objFile.Close

the replace function has an optional "start" and "count" argument. you can use that. Put count = 1, eg
[code]
Replace(strText, "Jim ", "James ",1,1)
[/code]
it will replace just 1 instance of Jim.

thanks! it works. and if I want to change it in two different rows? :)

then you can switch from using ReadAll, to Readline, ie go through the files line by line. That way you can determine which lines you want to stop replacing. this is just one suggestion.
