[mso] Re: Excel VBA Code - Compare Lists

Herbert,

You can try this with a formula unless you are determined to go VBA.

=3DIF(ISNA(VLOOKUP(VALUE(LEFT(A1,3)),Sheet1!$A$1:$A$3,1,FALSE)),"Prohibit=
e
d Area","OK")=20

Adjust value in left to point to cell with entire post code.  Adjust
number to be the same length as your part post codes.
Adjust Sheet1!$A$1:$A$3 to point to your part post codes
Adjust  "Prohibited Area","OK" to say what you want.

VALUE in VLOOKUP is required if your postcodes are all numbers since
left returns a string. Not needed if you have mixed alphanumeric codes.

False is required to max exact match (returns #NA if not a match there),
sort the part post codes ascending. =20

Copy the formula down the entire column for codes to check.

Subject: [mso] Excel VBA Code - Compare Lists

Hi Folks,

I was wondering if anyone could provide me with some guidance on how I
can get round a certain problem which is as follows:

=3D20

I am trying to compare 1) a list of full postcodes, on sheet 1 against
2) a list of part postcodes on sheet 2(eg areas we can't trade in)

=3D20

Step 1) take the first postcode of (a) above, test if it is "like"
(wildcard functionality) first part postcode in (b)

Step 2) if it is not "like" the first part postcode in b, try the
postcode from (a) in step one against the next part post code in(b)
(Basically test the first postcode against all part postcodes in b

Step 3) If the full postcode in a is "like" the part post code in (b),
select active row in a and delete that row.

Step 4) After it has tested the first full postcode in (a) against all
part postcodes in (b); or after step 3, move to the next full postcode
in (a) and repeat the process i.e. test that post code against the whole
list from (b)

=3D20

I think what I am struggling with most is the criss crossing between two
sheets and activating certain cells and then moving back to the other
sheet etc.

=3D20

Many thanks for your help

Herbert
