Find/Replace in text file?

[Guest]

Hello,

Can anyone help me on how to find and replace text within a .txt file using
vb.net?

Any help would be greatly appreciated!
Thanks in advance.

Dim fso, inputFile, outputFile
Dim str As String

fso = CreateObject("Scripting.FileSystemObject")

'1 means for reading

inputFile = fso.OpenTextFile("c:\testfile.txt", 1)

str = inputFile.ReadAll

'modify this string, replace required characters

str = Replace(str, "whatToReplace", "replaceWithThis")

'write back

outputFile = fso.CreateTextFile("c:\testfile.txt", True)

outputFile.Write(str)
