Our libraries (DLL's) are developer toolkits that can be used by programs written in all supported computer languages. Purchase a developer license for a specific product for one software language and use the same registered DLLs with all other supported languages for that product (i.e., purchase SEE4VB and use the DLLs with SEE4C). All versions of SEE use the same DLLs (SEE32.DLL or SEE64.DLL). However, the examples provided for each version were developed and tested using the specified computer language.
