Newbie question: Indexing through control array

[FG]

Hello,
I'm a newbie trying to write an application that uses a control array of
text boxes. I would like to fill the boxes with values I am receiving from
the comm port. So far so good on that. My problem is that I would like
for the user to be able to click on a text box and then when the value comes
across the comm port to have it fill that text box and advance to the next
box in the array. Conceptually it seems simple enough to me, but I can't
get the code to work. I would appreciate any suggestions or code. Thanks
in advance.

This is untested, top-of-the-head code so you may have to play around with
it a little. Here I'm assuming your TextBox control array is named Text1 and
that your control array indexes are sequentially numbered:

Indx = 0
For X = Text1.LBound To Text1.UBound
Text1(Indx).Text = GetCommPortDateFunction()
Indx = Indx + 1
If I > Text1.UBound Then I = Text1.LBound
Text1(Indx).SetFocus
Next

where the GetCommPortDateFunction is meant to be the method you are using to
get the comm port data.

Rick,
Your code will work for sequencing through the array starting at 0, but
I would like for the user to be able to set the focus on any text box, have
the value fill in and then index from that spot. I would also like it to
be flexible enough to repeat this "jumping focus" and then continuing if
the user wants.
Thanks

If you remove the Indx = 0 statement, the code should let you start at any
TextBox and cycle though them starting with that one. That line was included
to let you set the initial focus position. Removing that line and setting
focus by any means you want should be acceptable. The

If I > Text1.UBound Then I = Text1.LBound

statement insures that the focus will wrap properly at the "last" TextBox
which is why you should be able to start with any TextBox you want.

I am not sure exactly what you mean by "flexible enough to repeat this
'jumping focus' and then continue"?

Rick,
I still have a few questions. For one, is Indx just a procedure level
interger variable? or something else? Second I coded your example and still
can't get it to index from the box that has focus.

Private Sub Command1_Click()
For X = Text1.LBound To Text1.UBound
Text1(indx).Text = Text2.Text 'Instead of the sub
indx = indx + 1
If i > Text1.UBound Then
i = Text1.LBound
Text1(indx).SetFocus
End If
Next X

End Sub

Lastly, the code as written fills all of the array with the text2.text value.
Sorry if I'm not getting the picture, please bare with me.
Fred

The first thing you have to remember is that anyone answering a posted
question does not know exactly what is going on at the posters computer. So
we take guesses at to what we think is going on. My guess was that as an
individual piece of data came into the comm port, it would be assigned to a
TextBox and then the focus would be moved to the next TextBox. That is why I
offered

Text1(Indx).Text = GetCommPortDateFunction()

as the first statement *inside* the For-Next loop. The idea was that however
you receive the comm port data (one piece at a time), it would be done on
each loop of the For-Next loop (one piece of data per loop) and assigned
immediately to the TextBox having focus. The GetCommPortDateFunction()
function's name was supposed to imply that to you (although I just now see I
put Date instead of Data in the name). When you changed that implied
function call to Text2.Text, then you told the routine to loop through all
the TextBox(es) and immediately assign whatever is in Text2. There was no
attempt to get a new piece of comm port data on each loop any more.

As to the scope of the Indx variable -- I intended it to be local to where
the routine was posted, but that is not an absolute. Again, it depends on
what your code is doing and how it is doing it. Remember, the best I could
do is guess at your particular situation.

If you are receiving all your data to be displayed *first*, in one chunk,
and then dividing it up into pieces for display, then you would replace the

Text1(Indx).Text = GetCommPortDateFunction()

statement with some sort of code that grabbed the appropriate piece of data
on each loop of the For-Next loop. Again, hard for me to know what is going
on at your place. If you are still having trouble implementing my suggested
code, you will have to provide a lot more detail explaining how your code is
structured. Maybe even posting your code itself (providing it is not too
lengthy).
