Install Math Parser Component in Delphi
The Delphi IDE allows the developer to install the components that come as BPL package (a kind of DLL), or as source code (.cpp or .pas files) or as in DCU form (.dcu files).
The TbcParser Mathematical Expression Parser component is shipped as Delphi source code which can be used as a component in Delphi or C++ Builder. There are BPL package files for Delphi 2006, 2007 and C++ Builder
2006 for your convenience as well.
The evaluation version of TbcParser comes as BPLs, binary OBJ files (for C++ Builder) or DCU files (for Delphi) for which the installation procedure is similar.
If you are new to Delphi, for an example of installing BPL component packages in Delphi 2006, checkout our isapi component installaton page. The process is the same for all components.
