populate a list box with different data

hi, i have a list box on a userform that displays dta from a part of my
spreadsheet. the list will have a different number of rows at different
times but always the same amount of columns. I have worked out that
there will never be more then 200 rows to display so i am currently
using

private sub userform activate
listbox1.columncount = 20
listbox1.list = range("a1:u200".value
end sub

this ensure i get all the dat into the listbox. can i make it smarter
so the list box only displays rows with data in rather then all 200.
Although this method seems to work sometime whne i run the program i am
unable to select certain rows within the listbox. i.e i may have 20
rows in the listbox and i can only highlight 17 of them.

regards

john

John,

Try this

Private Sub userform_activate()
ListBox1.ColumnCount = 20
ListBox1.List = Range("A1:U" & Application.CountA(Range("A:A"))).Value
End Sub

bob,

thanks that works great,
i am still getting the problem of not being able to select certain rows
within the listbox, the list box is on userform2 and is accessed from
userform1, i can go back and forth through the forms and on about the
third time this happens, any ideas

john

Sure, your approach is probably screwed up. when you show useform1 and have
it show userform2 and userform2 then shows userform1 and so on, the original
userform1 has never unloaded since its event hasn't terminated.

In userform1 you should have

Private Sub Commandbutton1_Click()
me.hide
userform2.show
me.show
end Sub

In userform2, the button should unload userform2.

I suspect you have


In Userform1

Private Sub commandButton1_Click()
unload me
Userform2.show
End sub

in Userform2

Private Sub Commandbutton1_Click
unload me
Userform1.Show
End sub

Userform1 can't terminate until userform2 terminates. Userform2 can't
terminate until userform1 terminates. then things start to get screwed up.

tom,

this is how i have it

code from userform1

Private Sub CommandButton1_Click()
call results
end sub


then from the results sub

sub results ()

unload userform1

various code

userform2.show
end sub

then from userform2

Private Sub CommandButton1_Click()

call searchagain ()

end sub

sub searchagain ()

unload userform2

various code

userform1.show

end sub ()

i have check earlier from another posting that this method was ok what
do you think

john

i have just noticed that when i go to two the userform2 a second time
if the program brings up a row of data that appeared the last time i
loaded userform2, which it can sometimes its that data that i cannot
select. any ideas

john

Your doing exactly what I said causes problems.

I already gave you an idea - but if you don't feel you are having problems
or you don't feel that is the problem, then the suggestion can be ignored.

I WAS NOT IGNORING THE SUGGESTION IT WAS THAT THE WAY I WAS DOING IT
WAS NOT EXACTLY HOW YOU STATED I WAS DOING IT, THE WAY I WAS DOING IT
WAS CONFIRMED AS OK BY YOU IN A PREVIOUS POSTING SO I WAS JUST SHOWING
YOU HOW I WAS LOADING/UNLOADING SO YOU COULD SEE IF THERE WAS ANOTHER
PROBLEM, THANKS FOR YOUR HELP

If you are refering to this comment:

>The order in the original looked fine to me. What is the advantage or
>rightness of doing various lines of code prior to unloading userform1?

the only thing being addressed there was the order (which to me appeared
inconsequential). It didn't address the wisdom of or bless doing what you
are doing and it today's topic.

And, the code you posted does what I warned against. the fact that you do it
by calling a subroutine rather than doing it directly in the event does not
change that. If you want to key in on the word exactly, then change it to
substantially.

Rather than getting all lathered up, just ignore my post and do what you
know is best.

Hi John,

As you may recall you sent your me your wb in early April to look at your
problem re memory leaks and crashes. You had several userforms, each loading
others something like this:

In UF1
Unload Me
immediately followed by lots of code, including calling various other proc's
followed by -
UF2.show

... and similar in the other userforms, each potentially being loaded &
unloaded multiple times, and going round in circles.

In some cases other forms were being loaded from proc's in normal modules
which in turn had been called directly after an Unload Me statement in a
form.

I tried to explain why each successive form unload / load would inevitably
lead to problems and advised, in particular, not to put more code after the
Unload Me and suggested and how to do it.

Without the benefit of seeing your project or a snippet of code, Tom
correctly guessed your problem, and went on to suggest both what you should
do and what you should not do. In essence, pretty much the same as I wrote
to you off-line some while ago.

Regards,
Peter T
