Custom ActiveX Controls and DLLs

Access the Windows API or special features

You may have reason to use special features that aren't easily accessed or used by Visual FoxPro or by Visual Basic. Visual FoxPro doesn't handle C++ structures well on its own, for example. This makes an excellent opportunity to introduce an ActiveX control or DLL which can provide access to your programs.

Speed up processing

Sometimes intense string or numeric processing is required for an application in order to achieve more speed. A custom DLL or FLL (a DLL with special FoxPro hooks) is perfect for this type of application.

Restrict access

One of the more popular uses for a custom DLL is to restrict access to specific features in a Visual FoxPro program. In this way, users that haven't purchased full access won't be able to get it — at least not easily.
