[ltk-user] Saving entry content to file
by Louis A. Turk 03 Sep '10

03 Sep '10

Hi Peter Herth and everyone else, I'm rather new to Lisp and to LTK, but learning steadily. I'm stuck with a problem. I've successfully used ltk to create a form, but don't know how to save the data entered into the form to my database. I suspect that my problem is improperly supplying the data from the entry widget to the store-save-rec function (see line 279 below). But I may just have something else fundamentally wrong. Would someone please tell me what I'm doing wrong, and how to fix it? I'm using ltk 0.91 Thanks in advance! Lou PS Also, how do I clear all the fields in preparation for entering another record of data? ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;;; DICTIONARY AND INTERLINEAR MAKER ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; (in-package :lat-il) ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;;; Definations for the dictionary code. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; (defvar *recs* (make-array 100 :adjustable t :fill-pointer 0) "A vector of dictionary records.")
