Barcodes

This call sets the users serial number and is required to allow the DLL to function fully.

int WINAPI Barcodes(LPSTR szser)

A single call to Barcodes() 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 defaced barcode images and scrambled pattern strings.

Visual Basic declaration:

Private Declare Function Barcodes Lib "Dlsbar28" (ByVal s As String) As Long
