The dFont DLL
The dFont DLL is a Windows Dynamic Link Library which may be called from a variety of programs and environments. It accepts 4 parameters. Its basic role is to be given the characters you wish to turn into a barcode, and return the character which when printed in the appropriate font, will represent that barcode - including the start and stop characters and the check digit.
The 32 bit version DFONT32.DLL is designed to be called by 32 bit applications (such as programs created with Visual Basic). The DLL must be placed either in the directory that contains the application or in the Windows system directory (for Windows 9x) or the Windows System32 directory for Windows NT/2000/XP.
If the application you are using cannot find the required DLL an error message will be generated when calls are made.
Three groups of function calls are supported:
Group 1 calls generate a barcode string directly from data and barcode properties totally contained within the function call.
Group 2 calls generate a barcode string from a data string, using barcode properties specified in advance that are remembered as default properties.
Miscellaneous calls serve other functions but do not generate a barcode string.
