Here is allof what I could find (i am not a vb person)

Public Declare Function BUICScan& Lib "BUICAP32.DLL" (ByVal iJob&, ByVal lpFront$, ByVal FLen$, ByVal lpBack$, ByVal BLen$, ByVal LpCode$, ByVal LpLen$)

'// Declares for BuicScan
    Dim FLen As String * 255
    Dim BLen As String * 255
    Dim CodeLen As String * 255
    Dim mstrMICR As String * 255
    Dim mstrFront As String
    Dim mstrBack As String

mlngReturn = BUICScan(mlngSides, mstrFront, FLen, mstrBack, BLen, mstrMICR, CodeLen)
