Android Question Match String on .txt file

[German Buchmuller]

Hi, I want to know if the app can match a word (example: "germo") written on a txt file. How can I do that? Thanks!

Try this .. Ensure to check StringUtils library.

Sub GetUserName
  Dim TextReader1 As TextReader
  Dim User As String = "ABC"
  Dim Pword As String = "123"
 
  TextReader1.Initialize(File.OpenInput(File.DirRootExternal, "Text.txt"))
  Dim line As String
  line = TextReader1.ReadLine 
  Do While line <> Null
    If line = User Then  'if user is found then read next line to check password
       line = TextReader1.ReadLine
         If line = Pword Then
           Log ("User is OK")
         Else
           Log ("Incorrect password")
       End If   
     End If
  line = TextReader1.ReadLine
  Loop
  TextReader1.Close
End Sub

Following previous thread , I believe it would be best to store the Users name and password in a Database (for just this purpose it would be quite simple)

Avoid using TextReader (and TextWriter) unless the file is very large or is encoded in an encoding other than UTF8.

Dim s As String = File.ReadString(File.DirRootExternal, "Text.txt"))
