Use the len command: eks
text = "ksdjf"
len(text) = 5

use:

dim Password as string, length as integer

open "password-file.txt" for input as #1
input #1, Password
close #1

length = len(Password)

' len() is the command.  you may also use trim() to remove end spaces.  example:  len(trim(password))

To get the length of a string:
iLength = Len(sString)

To get the length of a string without the last character:
iLength = Len(sString)-1

To set the length of a string without the last character:
sString = Left(sString, Len(sString)-1)

in VB there is NO 'end character'....you are probably thinking of a C type string, which is terminated with a Null character (ASCII Code 0).  VB strings are NOT terminated that way.

TrimNull            
Returns the string up to the trailing null, or the passed string if none.
