Tutorial for C++ Builder Programmers
The following topics provide brief and simple examples to help you learn how to use the LEADTOOLS VCL.
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. |
Note: |
Please note that programmers using C++ Builder 4.0 or 5.0 must include the LEAD XX_BC.LIB files in any project. For more information about which XX_BC.LIB files to include and where they are located, refer to Installing VCL. In addition, please note that the header files are located in (LTVCL)\LIB\VCL\BUILDER4 or (LTVCL)\LIB\VCL\BUILDER5 and have the .hpp extension. |
Note: |
Please note that programmers must add the following for each project, depending on what compiler you are using: |
Builder 3.0
(LTVCL)\LIB;(LTVCL)\LIB\VCL\BUILDER3 to the library path
(LTVCL)\LIB\VCL\BUILDER3 to the include path
Builder 4.0
(LTVCL)\LIB;(LTVCL)\LIB\VCL\BUILDER4 to the library path
(LTVCL)\LIB;(LTVCL)\LIB\VCL\BUILDER4 to the include path
Builder 5.0
(LTVCL)\LIB;(LTVCL)\LIB\VCL\BUILDER5 to the library path
(LTVCL)\LIB;(LTVCL)\LIB\VCL\BUILDER5 to the include path
