Hot Tip....
fEd. Note: The following article originally appeared in FoxSpeak, the newsletter of the Capital District FoxPro Users Group in Albany, NY. It is being reprinted here from the May ‘94 issue of DevNotes, the newsletter of the Milwaukee Association of
FoxPro

As you use the Screen Builder, some objects will have properties that may annoy you. For example, all radio buttons must be the same width, and all must be in the same row or column. If you had a series of radio buttons, you may be able to fit them on the screen better if you could arrange each button individually. Also, when you select a button, the cursor will move to the next object after all of the buttons.
The following procedure, used as a valid, will allow you to make radio buttons work the way you want them to. Then, define each radio button as an independent object. In order to use this routine, you need to select a prefix code for each set of buttons. Define the three following variables:
where Prefix is your chosen prefix. For example, if the prefix is LEVEL, the variables would be LEVELANS, LEVELOBJ and LEVELLAST. Initialize these fields as follows: PrefixANS with the default value, PrefixLAST with the default field name, and PrefixOBJ with objnum(&PrefixLAST). Since you won’t know the object number, this initialization needs to be in the SHOW snippet. As you can see, it is best to choose a short prefix. PrefixANS will hold your answer, PrefixOBJ the previous object number, and PrefixLAST the object number.
Each button will then have the valid expression
R_BUTTON(Prefix, Button Number, Total # of
Buttons). For example, R_BUTTON(”LEVEL”, 3,
8).

We’ve come up with an easy way to submit articles to the
LA Fox Developer
Newsletter
one that has been overlooked for a long time.
You can submit your articles to either Chuck Williams
(72330,2326) or Barry Lee (72723,3422) on
Compuserve.
These articles can be on any FoxPro-related topic, whether it concerns a new technique you’ve discovered, a certain development technique you may favor over others, book reviews, etc.
The quality of this newsletter really depends on the members that support it, not just read it. And I think we’d all be surprised by the useful information that could be circulated around the membership.
