Finding txt-files and replacing text in them

Hi,

I'm looking for a way to search in txt files - I'm looking for a certain string - and then replace that string with another one.
I'm trying to figure out how this goes with Get and Put, but things haven't gone too well.

Someone out there could help me a hand?
Thanks,
Alain

Code:

---

Text1 = Replace(Text1.Text, "string", "string2") ' This will replace string with string2

---

Well, off course I thought about this solution myself
May I didn't make myself clear enough: I don't need a certain string from a file and then take it and change it for some use. I need the string IN THE FILE to be changed!
Replace will just change the string I took with Line Input, but it won;t change the tet in the file itself - and that is
what needs to be done. I guess I need to work with get and put, but the question is how. My problem is not finding and changing the string, but having it replaced/written in the file itself.

Save the file after replacing the string

Code:

---

Open "FileName" For Append As #1
Print #1, Text1.text
Close #1

---

Fon't use Append, use Output.

Code:

---

'search for a particular line and do something with it
'read the file into an array
'find the line you are looking for
' then read the array back into the file using Output
'so you can overwrite the original file

Option Explicit
Option Compare Text
 

Private Sub Form_Load()
    Dim myArr() As Variant, myLine As String
    Dim myComp As String
    Dim i As Integer, intNum As Integer
   
    myComp = "The line I am Looking for"
    intNum = FreeFile
'
'open file
    Open "C:\myfile.txt" For Input As intNum
   
  Do While Not EOF(intNum)
        i = i + 1
        ReDim Preserve myArr(1 To i) As Variant
        Line Input #intNum, myLine
        myArr(i) = myLine
     
        myArr(i) = Trim(myArr(i))
        If myArr(i) = myComp Then
'do whatever you want to here I change it to read "My Fixed Line"
        myArr(i) = "My Fixed Line"
       
        End If
       
    Loop
        Close #intNum

 'open file and save new contents
 
    Open "c:\myfile.txt" For Output As intNum
        For i = 1 To UBound(myArr)
            Print #intNum, myArr(i)

        Next
    Close #intNum
End Sub

Could be done easier too :

Code:

---

Dim buffer as string
Open "c:\myfile.txt" for binary as #1
  buffer=space(lof(1))
  Get#1,,buffer
  Replace(buffer, "what you want to find", "what you want to replace it with")
  Put#1,1,buffer
close #1

---

You forgot to replace the buffer with the updated version.

Code:

---

Buffer = Replace(buffer, "what you want to find", "what you want to replace it with")

---

Sorry, things happens, maybe i'm just tired :(

There is a problem with your method. Eg:
The text-file contains: "One big step for man"
Your two buffers might be for example:
1) "One big st"
2) "ep for man"
What happens if the user wants to find the string "step" ?........

I guess you don't mean my method? Hesaidjoe's search for whole lines...
