one way is to read the file into memory, then use the Split Method to split the line up at each comma. From there you can add specific text to the textbox.
can you please give the codes?
You can read the entire file into a string array by
Dim text() As String = System.IO.File.ReadAllLines(filename)
If the file contains many lines and you only want one (assuming you can uniquely identify a line by, for example, the email address) you can do
Dim email As String = "heburn@YAHOO.COM"
Dim text() As String = Filter(System.IO.File.ReadAllLines(filename,email))
Assuming a match was found, your line would be text(0). You can split it by
Dim fields() As String = text(0).Split(",")
Then the fields you want would be
Trim(fields(1))
Trim(fields(8))
it tried the code but after i change the filename the email string gets invalid
it says whenever i point the cursor on the email string "Value of type 'String' cannot be converted to 'System.Text.Encoding'" what can i do to convert that string?
Sorry. My mistake. The line should have been
Dim text() As String = Filter(System.IO.File.ReadAllLines(filename),email)
