Using Chilkat ActiveX Components in Visual FoxPro
Any of the Chilkat ActiveX components can be used in Visual FoxPro. For specific examples, please click on one of the links in the left rail of this page.
This page provides general information on using Chilkat ActiveX Components in Visual FoxPro.
Downloading and Installing a Chilkat ActiveX Component
Chilkat ActiveX components are non-visual components that provide technology solutions for email, Zip compression, encryption, XML, character encoding conversion, and more. Individual Chilkat components can be downloaded from http://www.chilkatsoft.com/downloads.asp.
The Chilkat component installer (the .MSI file that is downloaded) will install and register a Chilkat ActiveX component. Each component is packaged in a single self-registering DLL. For example, the Chilkat Mail ActiveX is ChilkatMail2.dll. The component installer does not create desktop icons nor does it install any runnable programs. Once installed, the component is ready to be used in Visual FoxPro.
Creating an ActiveX Object Instance
In Visual FoxPro, ActiveX objects are created using the CreateObject function. This requires a single ClassName parameter, for example:
The complete list of class names are given below:
Unlocking the Component at Runtime
Chilkat components are unlocked by making a single method call to UnlockComponent at the beginning of your program. This requires either a 30-day trial unlock code, or a permanent unlock code that is delivered after purchase. Any string can be used to automatically begin the 30-day trial:
Deploying Your Visual FoxPro Application
All Chilkat components are licensed for royalty-free redistribution, so you can redistribute the Chilkat DLLs with your application without having to pay a royalty per end-user. The Chilkat DLLs are standard self-registering DLLs, and most installer packages provide features for automatically registering DLLs that are included with your application. Chilkat DLLs can also be registered using the Windows regsvr32.exe utility.
