Try to do something like this:

	char *thestring; /* Pointer to the string where you want the answer */
	int item;
	Handle theitemhndl;
	DialogPtr thedialog;
	Rect therect;

	GetDItem(thedialog,itemnumber,&item,&itemhndl,&itemrect);
	GetIText(itemhndl,thestring);
	PtoCstr(thestring); /* If you want the string to be a c-string */

thedialog is your dialogptr from NewDialog or GetNewDialog. 
iteitemnumber sould be the items number in the itemlist.
In the int item, you will recieve the itemtype, and in itemrect the rectangle
for the item. Be sure to put all the '&' in right places. I have noticed
that sometimes forgotten '&' will cause BOMB!.

Hope this help.
