This call sets the users serial number and is required to allow the DLL to function fully.
int WINAPI Bar2Ds(LPSTR szser)
A single call to Bar2Ds() must be made before any other calls to the DLL, with the serial number provided either as a null-terminated string or as a BSTR variant.
In the absence of a valid serial number the DLL will behave as a testware version and produce scrambled barcodes and pattern strings. This scrambling may prevent samples of Databar and Maxicodes being unscannable.
Visual Basic declaration:
Private Declare Function Bar2Ds Lib "Dls2Dun" (ByVal s As String) As Long
