you cant
but if you want

you can read in the string and then parse it

Mid(StrFile,5,1) this gets the 5th character

so you can loop through it also

for i = o to len(strfile) -1
      debug.print "Character " & i  & " = " & mid(strfile,i,1)
next

Use:

Dim C As String
C = Input(1, #FileNum)

The VB6 help file gives this example:

Dim MyChar
Open "TESTFILE" For Input As #1   ' Open file.
Do While Not EOF(1)   ' Loop until end of file.
   MyChar = Input(1, #1)   ' Get one character.
   Debug.Print MyChar   ' Print to the Immediate window.
Loop
Close #1   ' Close file.

Be aware that reading a file character by character is probably about the slowest way possible to read a file, by a large margin. If your file is even moderately sized, you are better reading it line by line, or by block or something, and then in your program reading the individual characters.

fh2,

Thanks for the prompt attention to the question!  I'm glad to have helped.

Z_Beeblebrox makes a very good point, though.  Using:

MyString = Input(LOF(FileNum), #FileNum)

to read in the whole file, and then parsing it like Mikal613 suggested is typically a much faster way.  But I don't know your requirements and reading it one character at a time may be the best solution for you (so that you don't have to read in the whole file before you can process it).

Best of luck to you.
