Read the next line in a text file
Frederic,
This last post is getting closer to being much more clear (or at least I now
have an idea of what you are trying to do). Because I don't have the actual
text file, the code below is written on the fly. As a result, it's not
tested, and it isn't necessarily the "most efficient" way to do things (but
it is a good way to illustrate some additional programming concepts that you
may have not seen, namely arrays). I commented the code, so be sure to read
those comments as you look at the code below.
You'll have to check the logic inside the "Case "SPRCONTBTN"" syntax because
I have no way of knowing what you are truly looking for (i.e. check the
If...Then block of code). I simply added the "new" code in this section
based on your recent post. Your statement of "...usually in the text file
the word SPRCONTBTN is before PAYDETAILS..." is a bit bothersome to me. Do
you need to test for "PAYDETAILS" as the next line for each of the Case
conditions? If this is what you need, then let me know and we'll create an
additional procedure/function to systematically make this check very easy for
each of the Case conditions. However, you'll at least have one example
within "SPRCONTBTN" to work with (and test) for now.
In addition to the change within "Case "SPRCONTBTN"", please ensure that the
"Case "PAYDETAILS"" is doing what you anticipate. Also, you'll have to
determine if you now need code in the "Case Else" statement. (It's okay if
you don't have anything in the "Case Else" statement). You'll notice that I
left a simple comment in the Case Else section. (Again, use F8 repeatedly to
see how the logic of the program is behaving).
Let me know if this gets you closer to where you need to be.
Best,
Matt

Hi Matthew
Thank you for persevering with me and i really appreciate how you have
shown me a simpler and better way to write the code.
My main problem still exists though. As it is reading line by line I need
the following to occur. Usely in the text file the word SPRCONTBTN is before
PAYDETAILS, but sometimes there won't be the word PAYDETAILS in the next
line. So then I am trying to make that if the next line doesn't have
PAYDETAILS, then in the worksheet there will be either "N/A" or "-----".
Currently it is reading every line and if the next line doesn't contain
PAYDETAILS it is adding "-----" in the worksheet. If the text file has say
50 lines it will start placing "-----" on the worksheets in the relevant
columns until it finds the word PAYDETAILS and then it will add payment type,
date and dollar amount.
I'm hoping this is clearer.
Regards
Frederic

Fredric,
I've altered your code a little bit. I added a Case statement instead of
your If, ElseIf statements. (I think that the Case statement is a bit easier
to read. If you haven't used a Case statement before, the VBE Help
documentation has some good information on how it works. It acts very
similar to the If...Then statement. Also, take note of the comments listed
in the code below).
I'm still not 100% sure what you are trying to achieve. What your code is
set up to do is the following:
1. Test for "CEG_HEADER". If it exists, do something and move to the next
line of the text file.
2. If "CEG_HEADER" does NOT exist, test for "FILENAME". If "FILENAME"
exists, do something and move to the next line of the text file.
3. If "FILENAME" does NOT exist, test for "INTRCHGHDR". Etc.
....
If "CEG_HEADER", "FILENAME", "INTRCHGHDR", "RECIPNTDTL", "SPRPRODHDR",
"SPRCONTBTN", AND "PAYDETAILS" do NOT exist, insert the "----".
Thus, I don't exactly know what you mean by "If the word ["PAYDETAILS"]
isn't there then in the worksheet I need to place 'N/A'," as noted in your
first post. I say this because, as noted above, if "PAYDETAILS" does NOT
exist (meaning that none of the other words exist either and the code has
reached the "Case Else" section), then insert the "----".
Are you familiar with the Debugging tools inside VBE? If not, then at least
use the following to test and evaluate your code:
In the "Debug" menu, there is a "Step Into F8" option. Step Into will allow
you to evaluate your code one line at a time. As you evaluate your code
(i.e. press the F8 key) you will see a yellow line highlight syntax. As you
press F8, you will see the yellow line advance one line at a time. I think
that doing this simple exercise will help you see how your logic is behaving
and will hopefully help you see where/why the logic is not behaving as you
anticipated. Otherwise, you'll have to really spell out what you are looking
for.
For example, I don't know what you mean or intend when you say "...the
information retreived made only 4 rows on the worksheet, [but] columns L, or
M, or N used up 57 rows." Do you mean that columns L, or M, or N should have
used up only 2 rows (i.e. the two "CHQ" lines from your post should be on 2
rows only instead of spread out and separated by "----"?). How is the data
supposed to look? (For example, assuming from your post that the dollar
column is "A" and the subsequent columns move in alphabetical order [i.e. A1
= $773.75, B1 = 17092009, C1 = SUPERLIFE PTY, D1 = ----, E1 = ----, F1 =
----, etc. ] there should be the four rows of data (A1:C4) as shown in the
post, but E1 = CHQ, F1 = 12082009, G1 = $77.37; E2 = CHQ, F2 = 12082009, G2 =
$101.59; F3:G4 = ----).

Matt

Hi Matthew
This problem was my first original question, but I have probably not stated
it clearly.
The text files have lots of other information which I don't require. What
is happening with the macro below is that if for example the macro doesn't
find on the next line the word "PAYDETAILS" it places "-----" on column L, or
M, or N. Therefore if the information retreived made only 4 rows on the work
sheet, columns L, or M or N used up 57 rows. I have place an example below
and the code.
Hope i have made it clearer
