Hi All,

I am so stuck....

I am using the following code to copy a single row from "Sheet1" of the
"Copreco Daily Submission" workbook, to the next available row of the "Daily
Reading Master Log", of the "Copreco Master Log" workbook.

Everything works perfectly well.

Problem:
I want to add some code (and I don't know where) that makes sure the
'Reading Date' in the row of data in "Sheet1", doesn't match any reading
dates in the 'Daily Reading Master Log'. If there is a match, cancel the
procedure, otherwises, insert the new reading row as per normal.

Additional information:
Sheet1, 'Reading Date' is in column A, Row 2 - Always
'Reading Date' in Daily Reading Mater Log, is in column B

Any assistance would really be appreciated.

Many thanks,

Carlee,

There's a lot of code and comments to read through, but why not try
loading the "Daily Reading Master Log" dates into an array and then
compare the array to the "Reading Date"? If there is a match, Exit
the Sub procedure or cancel as desired.

For example (code not tested),

Dim masterLogDates
Dim readingDate
Dim a

masterLogDates = [range_of_master_log] 'or load the array however you
desire
readingDate = Range(...).Value

For a = LBound(masterLogDates) To UBound(masterLogDates)
If readingDate = masterLogDates(a) Then
MsgBox "Found a match between the 'reading date' and the 'master log
date'." vbOkOnly
Exit Sub 'or cancel/don't insert; whatever you want to do
End
Next

Without looking too deep in your code, you could put this step before
you "insert the new reading row as per normal."

I hope this helps. (You could probably also swing a VLookup function
as an alternative way).

Matt

hi matt,
I am not sure how to construct an array. Can you assist a bit further on
how to put the array together?

Carlee,

I'm not sure how much coding background you have, so I'll list some
example code. If you need more explanation then email me at meh2030
at gmail dot com and I'll send you a tutorial I wrote up on loops and
arrays.

You can define an array as having option base 0 or option base 1. If
you do not define the size of the array at declaration, you can define
the size with a ReDim statement later on in the program. There are
ways that don't require you to define the size (e.g. the Array
function or the Evaluate Method), but you'll then need to use the
LBound and UBound functions to extract data via a For...Next loop.
(As a side note, arrays in Excel can hold up to 60 dimensions. Most
people typically won't use arrays larger than 3 dimensions).

Here's one example.

Option Base 1
Sub testArrayOption()
Dim myArray(10) 'this array has 10 elements
Dim a

For a = 1 To 10
myArray(a) = Cells(a, 1).Value
'Comment: it could be written as myArray(a) = Cells(a, "A").Value
'Comment: it could also be written as myArray(a) = Range("A" &
a).Value
Next

End Sub

Here's another example that loads an array and then loops through the
array to compare values. The "[...]" are shorthand for the Evaluate
method (search Evaluate in VBE).

Sub testArray1()
Dim myArray
Dim myValue
Dim a

myValue = 10
myArray = Range("A1:A20").Value
'You could use [A1:A20]
Range("J1:J20").Value = myArray
'You could use [J1:J20]

For a = LBound(myArray) To UBound(myArray)
If myArray(a) = myValue Then
MsgBox "Found a match!"
End If
Next

End Sub

And here's one more example which will select two separate worksheets
that are not contiguous; the example uses the Array function (search
Array in VBE).

Sub arrayOption()
Dim myArray

myArray = Array(1, 3)
Worksheets(myArray).Select

End Sub

I hope this helps.
