Option buttons or check boxes

[Matt]

I am making a program and I want to either a radio button or check boxes to
make something appear when one of the boxes or buttons are checked. Here
is my problem I want the program to start with none of the boxes or buttons
check, but I also only want to be able to check one boxes or button, I don't
want more than one chosen. I can do this with buttons, but with buttons
the program starts with a button check and with boxes you can check more
than one box.

Thx

Matt,
Make the Check boxes members of a control array, and then, in the CheckBock_Click(Index)
procedure, you can turn off all of the checkboxes when one is checked, and
then turn ON only the one indicated by the Index passed to the procedure.
That should accomplish what you want.

Two options:
1) add another "none of the above" option button and make that True by
default
2) add code after the form is loaded and shown to clear the option box; VB
sets one true if all are false when it loads the controls but you can
override that

"selecting the wrong control"

This is a great site, but it neglects one difference, though.

You can't reliably have no selection in a set of option buttons.
With a set of exclusive check boxes, you can. Personally, I
would go for a set of options buttons that included a "None"
option, but there is some quality to the alternative argument.

It will also default one when the group get's focus.

True. A 'None' option is usually the best approach. It keeps the standard
action on the controls and is more explicit for the user.

Try setting all of their Value(s) to False in the Form_Activate event and see what
happens.

How does the "group" get focus?

It lasts only as long as the group does not receive focus. I
wouldn't call it gospel, but I don't think that tabbing through
controls should result in an edit.

Drop a TextBox and 3 OptionButtons on a form (in that order) in
a default Standard EXE project. When you run the program, Form1
should have the text box in focus, and the option buttons will
all be unselected. Tab takes you to the option group
(additional tabs do not go to the next optionbutton) and selects
the first optionbutton.

That's not how it works on my system -- VB6SP3 on Win98SE. The Tab key will not send focus
to the OptionButton group if no one of them is selected.

I set all of the OptionButton Value(s) to False in the Form_Load event. Doing this means
that no OptionButton will be selected. And when none is selected, then none appear able to
take focus. Only after one of them has been selected can the Tab key give focus to the
group (the selected OptionButton only, to be exact).

I've noted that your a fastidious man, so your description is
credible even though it is counter to behavior I've witnessed on
a wide variety of VB and OS versions. Please don't take it as
patronizing if I ask: Did you try the experiment I proposed?

Interesting. If you set only the first option button's value to False in
the Load event then tab takes you to the second button and "clicks" it.
If you set the first two then the third one gets focus. If you set them all
then none can get focus via TAB. Somebody must have been on something
strong to come up with something like that!

(VB6SP2 on Win2K pro)

Yes, I even added an additional TextBox and watched the focus oscillate between the two
TextBoxes only.

Give what I posted a try. Add two TextBoxes and three OptionButtons (although you can add
as many OptionButtons as you like). The order in which you add the controls should be
unimportant. Now, put this in your Form_Load event

Option1.Value = False
Option2.Value = False
Option3.Value = False

and run the project. Repeatedly hit the Tab key and none of the three OptionButtons will
receive focus. You must click on one of them to activate(?) the group. After clicking on
any one of them, Tabbing will now include the selected OptionButton in its sequence. As
long as the Value properties *all* OptionButtons in a group are set False, they will be
excluded from receiving focus.
