Re: Difference between a Command Button and a Label

Tom, thanks for your courteous reply to what I see now was a confrontational
tone in my remarks. I really must apologize for that. I did intend to
point out that I was familiar with using a label as a command button, as
were the people from whom I borrowed the idea, so I will admit I was puzzled
by what I took to be a request for acknowledgement. On another point, I
have read your many informed replies to questions in this forum, and I could
have assumed that you are familiar with Lebans' site. Also, I have to say
that I honestly thought I was replying to somebody whose name I did not
recognize, perhaps because I looked too hastily at the list of messages in
my newsreader, and clicked the reply button without looking more closely at
the message. No matter who posted, though, a courteous reply would have
been more appropriate. I am familiar with your postings in this forum, and
would certainly not have suggested that you do some research, because I know
that you are well aware of how to search newsgroups.

As for practical matters, I hadn't thought about the zero-width text box.

It is quite curious, and rather frustrating, that Microsoft does not allow
for colored command buttons. As you point out, there is certainly interest
in having that functionality. It is one of many points about which they
could probably do something if they cared to take notice, but the way in
which thinking is stirred at Microsoft is to me an inscrutable mystery. I
do not agree with the thinking that says since gray is the default it's good
enough, but we all make choices. I'm sure some of mine are questionable to
somebody with other priorities.

Thanks again for the kind tone of your reply.

Dear Bruce:

Thanks for your excellent comments.

You cannot place the focus on a label. Hence, you also cannot tab through
it. You can, however, tab though a text box with a zero width (hence it
is invisible without being Visible = False). The events of that text box
can function just as the events of a command button would, making the
action appear as though the label "has the focus" and can be "clicked"
with Enter. If such functionality is essential, it's not hard to implement
this. Or, you could just use a text box and inhibit any typing in it,
instead of using a label. I chose the label because of simplicity.

I, too, am slightly color blind, blue-green. I tend to avoid those
combinations as they may be difficult to distinguish. I've never heard of
yellow-pink color blindness (which are the first colors I tend to use) but
it's still a good point you make. Most of my colored labels are gray and
yellow, and occasionally pink as well.

The point of a tip isn't to assert "here is something new" but to inform
those unfamiliar with a possibility. That's what I'd like to convey with
my brief article. Some of my friends will see this here, and may choose
to post it on their web sites. It's a good thing to open it up for
comment, and get other good ideas. Some of the responses here show that
making colors available on a command button would be helpful. That may
even stir some thinking at Microsoft.

Mr. Leban's work is, as usual, outstanding. The point is not that there
are not alternatives. The first point is to expose the functionality of
putting color options on something you can click on. Which one of many
options is used to do this is not the main thrust of my suggestions. I
believe my article should also make reference to such alternatives. It is
certainly not the point that using a label is the only way to do this, but
that there is utility in doing something like this.

Thanks,
Tom Ellison

The idea of using a label as a command button has been around for quite
some time. A Google groups search should find quite a few entries on
this very topic. Some go into additional detail about using the Mouse
Down and Mouse Up events to simulate the look of a command button when it
is clicked. Some of the postings will be mine, but I do not claim (nor
have I even for one instant considered claiming) any sort of authorship,
nor did the person or people from whom I borrowed the idea. You would do
well, before claiming authorship or any sort of intellectual property
consideration, to conduct some research.
While it is true that a label will give you some formatting options not
available with command buttons, there are also limitations. For one
thing, a label can't be in your tab order, and label events can only be
triggered by the mouse. A label does not have a Got Focus, Lost Focus,
Enter, or Exit event (and maybe others, but these are the ones I can
recall offhand). These may not matter, but there are certainly
significant differences between the two types of control.
A Google search will reveal a number of places where you can download
free command button graphics that can be placed as pictures on command
buttons. I also use standard graphics for custom navigation buttons, etc.
I will just observe that my opinion about whether or not to use colors,
graphics, etc. is not necessarily the last word. Sometimes there needs
to be something other than gray. I would also like to comment, as a
person with color deficiency in my vision (aka color blindness) that some
color combinations are particularly troublesome, such as medium red or
green lettering on a textured gray background, or some combinations of
green and red together.
A graphic on a command button will leave the (gray) edges of the button
as a border. If you are troubled by that, and if you are satisfied with
a label's limitations as a command button, that is certainly an option.
For full command button functionality along with color options, one
choice may be found on Lebans site:

Dear Keith:

This is a tip. You are certainly permitted to take it or not.

I understand your concern about consistency of color coding. This can
be overcome by allowing the users to select colors that correspond with
their preferences, and saving them in a table. The users could then
standardize colors as they wish, especially if they have become
accustomed to a given scheme. That's actually a nice enhancement
possibility I hadn't considered before. If you like, I'll credit you in
a later version of this article for inspiring that. May I quote your
question:

"what happens if the users get used to one developer's colour coding and
then are faced with a different set from another?"

I would think the answer is to build an array and store in that the
selected colors for a few different label button types. If this is done
when the application opens, it would take no time to assign them as each
form opens and functions, resulting in those color changes.

I am not asking for a patent on an idea here, but on a modest level of
authors rights as a courtesy. The only consideration I ask is with
respect to duplicating what I have written, that I be given the
priviledge of modifying it or withdrawing it, and that I be named in
credit for writing it (not owning it). I do not think those who might
want it on a web site would have any problem with that. Several have
done so with other articles, and always gladly credit me by name.

I have found that, to attract a user's attention, coloring a label is
quite superior to having a command button's nicer shape. For example,
in the header of forms, I place command buttons colored yellow. My
users know these buttons expose combo boxes used to filter the form,
and they change to pale green when a filter is active. Click them
again and the filter is removed, the combo box is made invisible, and
it is yellow again. This becomes quickly intuitive to my users.
Usually after being shown only once how to use one they know how to
use additional ones without asking.

I recommend you carefully consider having a standard set of colors for
labels, and use them instead of command buttons.

The buttons in my apps are the default grey and I see no reason to
change them. They all have legends to identify their purpose to the
end user. I once flirted with different colours but IMO you end up with
a gaudy mess. Colour is also not much use if any of your users have any
degree of colour blindness. And what happens if the users get used to
one developer's colour coding and then are faced with a different set
from another?

Why do you think that you have some sort of copyright over the use of
colour coding? I'm not trying to be hostile, just wondered.
