How Do I Find and Replace....?

Hi, I'm trying to write a piece of code that will look for text thats inputted in my FindString text box in my Source text file and replace it with text in another text box and write it to my target file. How do I go about doing this. I've got this far and now I'm stuck. I know how to copy from one file to another but how do I find and replace.

Thanks

Private Sub cmdReplace_Click()
Dim sdata As String
Dim FindString As String
Dim ReplaceWith As String


FindString = txtFindString.Text
ReplaceWith = txtReplaceWith.Text

Open "c:\Source.txt" For Input As #1
Open "c:\Target.txt" For Output As #2

While Not EOF(1)
Line Input #1, sdata
Wend

Print #2, sdata

Close #1
Close #2
End Sub

Use the InStr function to find the text, and if you wish to replace all instances of certain text, you can use the Replace function.


InStr([start, ]string1, string2[, compare])
Replace(expression, find, replacewith[, start[, count[, compare]]])

So basically, it goes something like this:

VB Code:

Private Sub cmdReplace_Click() 
    Dim sData As String 
    Dim FindString As String 
    Dim ReplaceWith As String 
 
 
    FindString = txtFindString.Text 
    ReplaceWith = txtReplaceWith.Text 
 
    Open "c:\Source.txt" For Input As #1 
        sData = Input(LOF(1), 1)
    Close #1
    
    sData = Replace(sData, FindString, ReplaceWith)
     
    Open "c:\Target.txt" For Output As #2 
        Print #2, sData
    Close #2 
End Sub

That was a faster method, if you wish to use what you are currently using with Line Input, it can be done like this:

VB Code:

Private Sub cmdReplace_Click() 
    Dim sData As String 
    Dim sText As String
    Dim FindString As String 
    Dim ReplaceWith As String 
 
 
    FindString = txtFindString.Text 
    ReplaceWith = txtReplaceWith.Text 
 
    Open "c:\Source.txt" For Input As #1 
        Do Until EOF(1)
            Line Input #1, sData
            sText = sText & sData & vbCrLf
        Loop
    Close #1
    
    sText = Replace(sText, FindString, ReplaceWith)
     
    Open "c:\Target.txt" For Output As #2 
        Print #2, sText
    Close #2 
End Sub

That would be another way. And also, opening a file, storing it in a variable, and closing it is probably much better than opening two files at once and finding/replacing text in one and writing to the other. Just less complicated :rolleyes:.

Thanks for your help mate. You couldn't have made it any clearer.
