Comparing a string to a line of text in a text file

I currently have a value (strString) that may be something like this:

mwmiller78ANDsons

I want to search a text file to see if there is the same value but with spaces

i.e. mwmiller78 and sons

If the program finds such a value, it needs to replace strString with the new found value. If it locates such a value, the cycle will end otherwise it will end at EOF.

How would I do this?
TIA

Take the string you wish to compare ( IE:  a line of text from the text file ) and something like this:

Dim newString as String = myComparingString.Replace("mwmiller78ANDsons", "new string value")

Try following

For each Line As String in IO.Files.ReadAllLines("path")
     if Line.Contains(" " & strString & " ") Then
        'Not sure what you mean by [i]If the program finds such a value, it needs to replace strString with the new found value. [/i]
     End If
Next

Got it. Here's what I meant. (Can obviously be simplified...my rough draft)

    Public Function FixSpacing(ByVal fs As String)
        Using reader As New System.IO.StreamReader(strTextFile2)
            While Not reader.EndOfStream
                Dim fsLine As String = reader.ReadLine()
                Dim fsLineRem As String = fsLine.ToString.Replace(" ", "")
                If fsLineRem = fs.Trim Then
                    fs = fsLine.ToString
                    Exit While
                End If
            End While
        End Using
        Return fs
    End Function
