	I want to save the editable texts in my dialog for next launch.
I need some help to get it work.  Here is my source:

_____________________________________________________________________

typedef union res_select {
	unsigned long RType;
	unsigned char cRType[4];
} res_select;

void main(void)
{
	short 		item, itype;
	Boolean 	done = false;
	Rect		box;
	Handle		ithdl, ditl_hdl;
	DialogPtr	Dptr;
	char		string[80];
	res_select	type_res;
	ResType		res_type;
	
	InitGraf((Ptr) &qd.thePort);
	InitFonts();
	InitWindows();
	InitMenus();
	TEInit();
	InitDialogs(nil);
	
	
	Dptr = GetNewDialog(155, nil, (WindowPtr)-1);

	while(!done) {
		ModalDialog(nil, &item);
		switch(item)
		{	case 1:				/* OK */
				done = true;
				break;
			case 2:				/* Cancel */
				done = true;
				break;
			default:
				break;
		}
	}

				
	GetDItem(Dptr, 3, &itype, &ithdl, &box);  /* Editable Text */
	GetIText(ithdl, string);
	p2cstr(string);
	printf("%s\n", string);
	
	strncpy(type_res.cRType, "DITL", 4);
	res_type = type_res.RType;
	ditl_hdl = Get1Resource(res_type, 4877);

/*  I got a handle for the Item Lists, Inside Mac told me that only
	the copy of item list read from resource file was used after 
	GetNewDialog was called.  How can I find this copy in the memory
	and link the above handle to it?  Then I only need to use the
	following line to update my dialog for next launch.
*/
	
	ChangedResource(ditl_hdl);
	DisposDialog(Dptr);
}

	Thanks for any help in advance.
