A good selection of complete example programs is included demonstrating how to send and receive email using the library. The SEE4FP library can also be used with any Windows application capable of calling the Windows API.

The SMTP/POP3 Email Component Library for Visual Foxpro supports all versions of VFP.

The SMTP/POP3 Email Library (SEE4FP) can be used in the development of 32-bit FoxPro applications running under Windows XP through (32-bit and 64-bit) Windows 11. The evaluation version of SEE4FP is fully functional. Registration is $139 for email delivery and includes one year of free updates.

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 SEE4FP and use the DLLs with SEE4C). All versions of SEE use the same DLL (SEE32.DLL). However, the examples provided for each version were developed and tested using the specified computer language.
