2. Library usage guide for Visual Basic 6.0
Using Protect-U library with Visual Basic 6.0 is very simple and convenient. We will only need two files from
Proctect-U library (see chapter 1.1): “ProtectU.dll” and “DIO.sys”. These two files must be put in the same directory
as the user-application directory.
To use the Protect-U library, just put the load library commands from Visual Basic on top of the application
source-code (see picture 2.1). After that, the functions exported by Protect-U library will be usable like normal
Visual Basic functions.
Example:
Private Declare Sub InitSecuritySystem Lib "ProtectU.dll" (Optional ByVal iobase As Integer = &H200)
Private Declare Sub CloseSecuritySystem Lib "ProtectU.dll" ()
Private Declare Sub ReadStatus Lib "ProtectU.dll" (ByVal StatusString As String, _
ByVal Status As Integer)
Private Declare Function CheckId Lib "ProtectU.dll" (ByVal ManufactureCode As String, _
ByVal SerialNumber As String) As Integer
After the “make” process, remember to copy “ProtectU.dll” and “DIO.sys” file to the directory where the executable
files is run (see picture 2.2).
