using Ok / Cancel button

[nila_joy]

HI all,

 

I am facing a new type of problem, I can understand the problem, but don't know how to solve it...

 

This is a part of a big program , which have many nesting dialog boxes, so many user inputs..

 

if I give all user inputs and press "OK" button, its working fine .. but if I press "cancel" button middle of the program, its getting hanged..

 

I want it like this ..

 

1. if i press "OK" button without all users input, it will show "Data insufficient" and terminate all.

 

2. if i press "Cancel" button middle of the program, it'll terminate all and will back in to command line.

 

Plz help..

 

(action_tile "conv" "(done_dialog 4)")
   (action_tile "dp" "(done_dialog 5)")
   (action_tile "beam_1" "(done_dialog 7)")
   (action_tile "beam_2" "(done_dialog 8)")
   (action_tile "dir" "(done_dialog 6)")
  [color=red] (action_tile "ok" "(saveVers)(done_dialog 1)")
  (action_tile "cancel" "(done_dialog)"[/color])
   (action_tile "stool_start" "(stool_function)")

If you provide a callback for the button whose key is "accept" or "cancel" (usually the OK and Cancel buttons), the callback must call done_dialog explicitly. If it doesn't, the user can be trapped in the dialog box. If you don't provide an explicit callback for these buttons and use the standard exit buttons, AutoCAD handles them automatically. Also, an explicit AutoLISP action for the “accept” button must specify a status of 1 (or an application-defined value); otherwise, start_dialog returns the default value, 0, which makes it appear as if the dialog box was canceled.
