// Function Name: InitDialog
// 
// Purpose: Smartphone2002 Interface Initialization
//
// Arguments: Handle to the dialog to initialize
//
// Return Values:
//	TRUE if initialization was successful
//	FALSE if initialization failed
//
// Side Effects:
//	Sets gbUseDefault to TRUE and gbSendConfirmation to FALSE
//	Sets all the global HWNDs
//	Checks the Default checkbox
//	
// Description:
//	The purpose of this function is to abstract some of the interface 
//	initialization from the actual program functionality so that the program
//	can more easily be ported to other platforms.
