I'm not sure if this is what you want but check out this thread

http://www.stata.com/statalist/archive/2003-03/msg00070.html

using that as a model I wrote a dialog box/ program where values of spinners

SPINNER sp_q1_r1 @ spyincr splen ., ///

label("Spinner one") ///

min(0) max(1000) default(30) ///

onchange("program spq1_chg")

....

if changed, call a program at the bottom of the dialog file

PROGRAM spq1_chg

BEGIN

put "prspin 1 " main.sp_q1_r1 " " main.sp_q1_r2 " " main.sp_q1_r3 " " ///

" " main.sp_q1_r4 " " main.sp_q1_r5 " " main.sp_q1_r6 " "

stata

END

which then builds a command line and invoke stata to run an ado file called - prspin.ado

the ado file does some calculations and then returns a value into 1 of the six spinners

with this statement

.prevrev_dlg.main.sp_q1_r6.setvalue "`val'"

(using the class system to set a label or value in this case)

a pretty specific operation but it might be generalizable to what you are interested in.

I am currently working on a dialog program which is meant to have a

different dialog depending on the number of groups entered in the first

window. I.e. if the use enters 2 groups in the main window, then he will

find two boxes to enter a value in on the options window, and if he

dialog window.

dialog language for passing information between two dialog windows.

Thomas also suggested letting the user specify the desired number of

groups with RADIO buttons. This is a good solution which could possibly

be enhanced by using a COMBOBOX or LISTBOX. The general idea is to force

the user to specify how many groups are expected. With this information,

the event handlers for that control, can show and hide additional EDIT

boxes or other controls located on the same tab or even other tabs.

However, they cannot control other dialog box windows.

Sophie did contact Stata technical support and has been provided with

the information above. I thought others might be interested, so I decided

to post a follow up here.

You left out the other part of my answer... where I suspected that it might

be doable "by

invoking an .ado and/or by using some of the non-public features of the

dialog language."

So, I'll ask directly: Is it possible to capture the numeric value of one

control then use it to manipulate the event handlers for other controls?
