Description

One or more Radio Button objects may appear inside the Format section of a UI_DLG_BOX() function. If you are testing the value of the selected radio button, it is advisable to use ALLTRIM().

Example 

The following script displays a dialog with three radio buttons: Picture

mode = 1
result=ui_dlg_box("Title",<<%dlg%
Filename: .32filename;
Open as? ;
(mode={Shared,Read only,Exclusive});

%dlg%, <<%code%
if a_dlg_button = "mode" then
    if (alltrim(mode) = "Shared") then
        do something
    end if
end if
%code%)

The next script uses a CR-LF delimited list of choices.

choices = "Shared" + crlf()+ "Read only" + crlf()+ "Exclusive"
mode = 2
result=ui_dlg_box("Title",<<%dlg%
Filename: .32filename;
Open as? ;
(mode=choices);

%dlg% )

The next script uses an array of choices.

dim result as N
dim choices3 as C
choices1 = "Shared"
choices2 = "Read only"
choices3 = "Exclusive"
mode = 3
result=ui_dlg_box("Title",<<%dlg%
Filename: .32filename;
Open as? ;
(mode=choices);

%dlg% )
