1- Add CPDB support to your application (CPDB library)

C language

Introduction

CPDB is a Palm shared library. To add CPDB support to your C application, you must only open the library, it's very easy and some Macro are provided to simplify the manipulation.

The CPDB library, a little prc file, must be installed with your application. For your testing session you must install the lib on the POSE Emulator, like another application.

•  Run POSE emulator
  
•  Drag & drop the CPDBSTD.PRC file on POSE emulator
  
•  Save the session with : right-clic/Save on POSE emulator

•  Run Hotsync Install tool (in the Palm Desktop section of your program menu)
  
•  Clic on [Add] button, browse to select "CPDBSTD.PRC" in your cpdb.net installation directory
  
•  Clic on [Done] button
  
•  Hotsync the Palm device

It's very easy to install CPDB library each time you run your test or debug session.

•  Open your project and clic on [Project/Properties] menu
  
•  Choose you settings on the combo box, most of time you choose "Debug" settings
  
•  Clic on the [Debug] tab
  
•  On the right of the "Load Additional Applications" field, clic on the [Add] button (the paper bitmap button)
  
•  Browse to select "CPDBSTD.PRC" in your cpdb.net installation directory
  
•  Clic on [OK], it's done !

Do the same way to install a CPDB database for use with CPDB.

Some addition must be done on your main.c and your application header file.

In main.c :

- Add the following line before the first function of your code :

// #include ...

CPDB_USELIB

// First function

Note : do not type a ";" on the end.

- Add the following line in your "StartApplication" or PilotMain* function :

static int StartApplication(void)
{
	CPDB_OPENLIB
	
	FrmGotoForm(frmMain);
	return 0;
}

* Before the first form is opened

Note : do not type a ";" on the end.

- Add the following line in your "StopApplication" or PilotMain* function :

static void StopApplication(void)
{
  FrmCloseAllForms();



  CPDB_CLOSELIB
}

* Before the end of execution, after the "EventLoop" and AFTER closing forms (by this way, you can close your databases in the FrmClose event).

Note : do not type a ";" on the end.

In the application header file :

- Add the following lines in any place :

#include "CPDBSTD.h"

CPDB_EXTERN_USELIB

You need to put the "CPDBSTD.h" file in your project directory. You can find this file in the CPDB installation directory.

Note : do not type a ";" on the end of the CPDB_USELIB line.

Four line to add, your application is CPDB ready !
