Aler function..

How to set "Alert" function so the appearance (dialog box) will not disappear (closed) if click the "X" button at upper right unless click "OK".

Example the funtion: (alert "Are you agree")

Are there appearance of Alert with option OK-or CANCEL, so if click Cancel then the action didn't execute.

Example, I put Alert when open a file, but if I click cancel the file will not opened.

Regards,

Pither:)

The alert function does not have other options. You will have to write you own OK/CANCEL dialog box so if the user clicks OK it returns 1 and if the user clicks cancel it returns 0 then have your code respond as needed

Sounds like you are wanting a modeless dialog, see here for more info:

http://www.cadtutor.net/forum/showthread.php?52498-Mode-less-dcl-dialog

when creating a dcl try something like this:

 
: row {
 ok_button;
 spacer;
 : button {
   key = "cancel";
   label = "Cancel";
   fixed_width = true;
 }
}

Make sure to leave out is_cancel = true;

(action_tile "cancel" "(done_dialog)")
