Tutorial for Visual C++ 4.0 Programmers

The following topics provide brief and simple examples to help you learn how to use the LEADTOOLS ActiveX. Note that the ActiveX requires the MFC 4.2 files, which are described in System Files Updated.

Implementing the LEADTOOLS ActiveX in Visual C++ 4.0 and later is much different than with earlier versions of Visual C++. These instructions were developed with versions 4.0, 4.2, or 5.0 and were tested with version 5.0.

For general information about the syntax requirements of this interface, refer to Visual C++ 4.0 Syntax.

Note: These tutorial examples are intended to be easy to understand and easy to test. The example programs in the EXAMPLES subdirectory provide more in depth design and more detailed code.
