Not a problem.I'll try to clarify:
In your original request, you said that you "wanted to bring up a list".
The way you accomplish that is with a userform.However you want to come up with
the list, you then use this list to fill in the listbox in the userform.
So, what *I* did was create an initialize event for the form such that, when
the form is "shown"
(Userform.Show)
Then, the initialize even runs to create a list and add it to the listbox of
the form.
Then, the second macro is tied to the "go" button (I called it "delete")
so both macros are required, but the form may change based on how you're using
it.
For instance:If you are creating the list of values BEFORE you open the form,
then your initialize event simply has to cycle through your list and add the
values to the listbox.(instead of both creating the list and adding it)
Next, you either have to have the button to process the selected values to
delete, OR you could make a Terminate event so that it processes the selections
when you close the userform.(I'd advise against that, since if you choose to
Cancel, you'd have to make sure you UNSELECT any entries first!)
Now:you've mentioned that you want to run this cleanup routine after a PORTION
of the data has been processed.Does that mean that you only want to
list/address the records you've processed?That is:- If you have 1000 records-
after 200 records, the userform obtains unique values FROM ONLY THE 200
RECORDS.- You make your selections and the macro button deletes the selected
records, but ONLY FROM THE FIRST 200- Then the macro proceeds.
If that's how you want it to go, I have a "caution".-You've processed 200
records (the "pointer" is now at record 201)-You select and delete selected
record values, which deletes 10 records.
Your pointer is still at record 201, but the previous record 201 has been moved
to record 191.So, when you proceed, your macro would effective skip 10 records.
That's the reason that in my macro, you'll notice the Delete loop starts at the
end and moves UP
For nRow = nRows To 2 Step -1
You'll want to do the same when you delete from your first 200 records.
does that make sense?

Hi Paul,
I apologise for the confusion. You are right I did not fully comprehend yet
what you were proposing, so was probably early in forming an opinion on part of
it!
Let me briefly describe the situation I want to accomplish.
1) I have a sheet of data that I run a macro on.2) At a certain point, let's
say after 20% of the code has already executed, I will want the macro to call
up a message box of unique locations (I have no problem getting the list made &
removing duplicates)3) The user will scroll through box, clicking a check mark
next to the ones they want to select.4) They will then hit the button in the
message box, at which point the code will continue to the next step, which is
deleting any record with a location matching one of the checked ones.
Question: are the two sub() you proposed complementary, and I need to integrate
both of them, or are they two different options for the same thing? As I
mentioned on Friday, this is completely uncharted territory for me.
Thanks again!

You response is a LITTLE confusing, but it may be that you didn't read the
entire post.
Your original question was:
I'm running a macro to process some data over several columns. At a midway
point of the code, I need the macro to bring up a list of possible names. The
user then can check the ones they do not want, click OK, and then the macro
will go on to delete all records connected to that name.
The names are in column A, and repeat.
How can I call up a list of all unique names in column A, with a check box
available for the user to scroll through and pick all the names they wish to?
In my response, I said:
I created a userform (called Form_Records)that contained one listbox called
Lst_Typeand a button called "Btn_Delete".
You can call the button "Btn_OK" and have the caption read "OK",so that once
the user selects the keywords to remove, they then "Click OK".
Basically, the approach is:1) Read through data and collect "unique" values
from column "A"2) Open a userform and the values to a listbox.3) Once items are
selected, the "OK" button will then store list of items to be deleted.4) Cycle
through data and delete rows containing selected keywords.
The technique (or "trick") here is in collecting of the list of unique
values.The most common method is to create an array and add the items to the
array.However, to check to see if the item is already in the array requires to
loop through the array:
Flag_Exists = falseFor inx = 0 to ubound(strArray) if (NewItem =
strArray(inx)) then Flag_Exists = true Exit For end ifnext inxif (not
flag_Exists) then 'Add Item to strArrayend if
This works for small data sets, but if you have 5000 rows, the code has to loop
through the array 5000 times!(you can do things to reduce the number of
iterations, like: declare the array without a "size" then redim the array and
increase the size each time you add an item, or declare the array with a size
larger than the anticipated number of unique values and initialize the array
with blanks. Then break out of the above loop when the array value is blank.
I like using the Dictionary Object. It eliminates the need for looping through
an array, checking values, and you don't have to anticipate the maximum number
of values.It's be REALLY COOL if the object had a "sorted" property, but I
guess you can't have it all!Paul------------------------------ -----------

Hi Paul, this sounds pretty good. I'm new to working with these type of
objects, so I'll have to read through clearly. One thing I notice, if I
understand your code correctly, is that I do not want to have to click a button
to run the code, but rather have it in the middle of my sub(), or else call it
from my sub(). But once I have it working, I can probably figure that out.
Work done for the day, so I'll let you know Monday if it was successful. But I
wanted you to know I appreciate the prompt response!--
