I am reading data from a flat file.  The data in the field is a 0.  I am reading it in as a String value because if the data does not exist, the fill the location with a blank.  I then try to covert it to a boolean value but get a system.format problem.  What could be causing this problem.

Thanks
Kenny


Here is the code


Dim migrant As String
 migrant = Val(Mid(strLine, 102, 1))
  migrant = Convert.ToBoolean(migrant)

you cant convert a 1/0 to a boolean ...

instead use

dim foo as integer = Convert.ToInt(migrant)
dim val as boolean = (foo = 1)

or you can just put in an ifstatement if thats clearer to you ...

dim  val as boolean = false
if migrant = "1" then
    val = true
end if
