HOW: Developing C++Builder applications that manage profiles
The information in this article applies to:
- ProfileKit 4
Summary
You can develop C++Builder applications that manage speaker profiles using your favorite version of C++Builder.
More Information
ProfileKit 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 ProfileKit C++Builder classes within your application, first add a project reference to the C++Builder header include files:
- Within your C++Builder project, select Project Options.
- Select the C++Builder compiler options
- Add Include path reference to the ProfileKit header files directory: C:\Program Files\Chant\ProfileKit 4\Win32\CBuilder\include
To access the ProfileKit C++Builder classes within your application, add a reference to the ProfileKit Header file in your C++Builder application header file:
#include "cchantpm.h"
Add a reference in your C++Builder application source file to the ProfileKit code needed to dynamically load and unload the runtime DLL:
#include "CChantProfileKit.cpp"
Object Instantiation
Declare a global variable for the ChantPM class, instantiate an instance, set the license and serial properties, and set the event handler message.
Add the following to your application header file:
protected: void __fastcall OnHasEvent(TMessage& msg); BEGIN_MESSAGE_MAP MESSAGE_HANDLER(WM_APP+6, TMessage, OnHasEvent); END_MESSAGE_MAP(TForm) private: // User declarations CChantPM* ChantPM1;
Add the following to your application source file:
ChantPM1 = new CChantPM(); // Set license properties ChantPM1->SetStringProperty(CSPLicense,"LicenseRegistrationNumber"); ChantPM1->SetStringProperty(CSPSerials,"LicenseLicenseSerialNumber"); // Define the HasEvent callback message ChantPM1->SetWindowMessage(Handle, WM_APP+6, 0, 0);
Event Callbacks
Event callbacks are the mechanism in which the component library sends information back to the application such as import/export operation state, training state, or there was an error.
void __fastcall TForm1::OnHasEvent(TMessage& msg) { int numberOfEvents = ChantPM1->GetResourceCount(CSREvent,0,0); for (int i = 0; i < numberOfEvents; i++) { // Get the event from the event queue CChantPMEvent* pEvent = ChantPM1->GetChantPMEvent(0); switch (pEvent->GetChantCallback()) { default: break; case CCSRProgress: { ... break; } } ... // Remove the event from the event queue ChantPM1->RemoveResource(CSREvent,0,0,""); 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 CProfileKit.dll to the target system and place in the same directory with your application.
