Calls from VB

One call that is useful for Visual Basic 6 or VBA applications that need to use the DLL for creating font-based barcodes is

Int WINAPI setData(LPBAR2D bc, LPCSTR data)

which passes a Basic string (data) into the bc.string member of the BARCODE2D structure and insets the length of that string into the bc.c_number member. This allows a BARCODE2D structure to be modified with a simple call without requiring the developer to convert a Basic string into a C string.

Two additional calls are available within the DLL, although they provide very limited functionality. They were designed for specific uses within older dLSoft products and are should be regarded as obsolete, having been replaced by Group 2 calls. They are included only for compatibility with previous versions.

Int WINAPI BarC2w(int code, LPSTR string, int pa, int wid, int ht, int aspec, int linered)

Int WINAPI BarC2wb(int code, LPSTR string, int len,int pa, int wid, int ht, int aspec, int linered)

See reference section for details.
