The information in this article applies to:

  • GrammarKit 4


You can develop C++Builder applications that manage grammars using your favorite version of C++Builder.

More Information

GrammarKit includes C++Builder header files comprised of the C++Builder classes that manage grammars and automatically load and unload the runtime DLL.

To access the GrammarKit C++Builder classes within your application, first add a project reference to the C++Builder header include files:

  1. Within your C++Builder project, select Project Options.
  2. Select the C++Builder compiler options
  3. Add Include path reference to the GrammarKit header files directory: C:\Program Files\Chant\GrammarKit 4\Win32\CBuilder\include

To access the GrammarKit C++Builder classes within your application, add a reference to the GrammarKit Header file in your C++Builder application header file:

#include "cchantgm.h"

Add a reference in your C++Builder application source file to the GrammarKit code needed to dynamically load and unload the runtime DLL:

#include "CChantGrammarKit.cpp"

Object Instantiation

Declare a global variable for the ChantGM class, instantiate an instance, set the license and serial properties, and set the event handler message.

Add the following to your application header file:

void __fastcall OnHasEvent(TMessage& msg);
MESSAGE_HANDLER(WM_APP+4, TMessage, OnHasEvent);
// User declarations
CChantGM* ChantGM1;

Add the following to your application source file:

ChantGM1 = new CChantGM();

// Set deployment license properties

// Define the HasEvent callback message
ChantGM1->SetWindowMessage(Handle, WM_APP+4, 0, 0);

Event Callbacks

Event callbacks are the mechanism in which the component library communications information back to the application such as compilation is complete or there was an error.

void __fastcall TForm1::OnHasEvent(TMessage& msg)
    int numberOfEvents = ChantGM1->GetResourceCount(CSREvent,0,0);
    for (int i = 0; i < numberOfEvents; i++)
        // Get the event from the event queue
        CChantGMEvent* pEvent = ChantGM1->GetChantGMEvent(0);
        switch (pEvent->GetChantCallback())
            case CCGMDone:




        // Remove the event from the event queue
        delete pEvent;

Deployment Checklist

When you are ready to deploy your C++Builder application, you need to ensure you have a valid license, bundle the correct Chant component library, and configure your installation properly on the target system. Review the following checklist before deploying your applications:

  • You may deploy your C++Builder application to any system with a valid license from the Chant.
  • Copy CGrammarKit.dll to the target system and place in the same directory with your application.
