Is there an array pointer available in VBA? I use it in other languages to
easily and quickly sort and search arrays. My problem is I have two very
large spreadsheets and want to get data from one to the other based on a link
and the arraypointer would make this easier in my opinion. A simple vlookup
formula in the spreadsheet is very slow for a large qty of numbers so I don't
really want to use it. Any ideas?

Mike,

VBA does not use pointers.

A better explanation of what you are doing may lead to some suggestions on ways to improve speed....

Here is what I do. I read into Dataarray() all my entries in a spreadsheet
(about 5000). The array is like this: Dataarray(REC#,1)=Account #
DataArray(Rec#,2)=Account description if there is one (if it is a valid
account). To fill in the second element I do this:



Windows("Chart of Accounts.xls").Activate
Sheets("Entire Chart").Select
Let Counterx = 0
For YY = 1 To X
Let XX = 0
Set myRange = Range("A1:A65000")
flag = 0
For Each c In myRange
Let XX = XX + 1
If c.Value = DataArray(YY, 1) Then flag = 1
If flag = 1 Then
Exit For
End If
Next
If flag = 1 Then
DataArray(YY, 2) = Cells(XX, 2)
Else
Let Counterx = Counterx + 1
BadAccts(Counterx, 1) = DataArray(YY, 1)
'MsgBox ("Account " & DataArray(YY, 1) & " is not in the chart of
accounts!")
End If
Next

This code takes about 45 minutes to go through 5000 records. Any
suggestions would be welcomed.

Mike,

Not sure where your Account#/Account desc table is, but assuming that it is in columns A and B

For i = LBound(DataArray) To UBound(DataArray)
DataArray(i, 2) = Application.WorksheetFunction.VLookup(DataArray(i, 1), Range("A:B"), 2, False)
Next i

But why are you putting this into an array? You could just use the VLOOKUP whenever you want the
value.

I don't have to put it into an array. I just want the description for the
account in my journal entry file so that I can verify it is a valid account
before I upload it. I will see how this goes. Thanks.

Bernie, This works tremendously! Instead of 45 minutes, it takes less than
45 seconds. Just one question, the LBound and UBound, does that stand for
lower and upper boundary or something like that?

Mike,

LBound and UBound are used to read the lower and upper bounds of arrays whose size you don't know.

If you had coded

Dim DataArray(1 to 5000) As Double

then it would be okay to use

For i = 1 To 5000

But a lot of operations return arrays of unknown size, so using LBound and UBound to read the size
makes sense. There is one other complication - Option Base, which can be used to set the Lower
bound of arrays automatically...

Take a look at this link:

One of the FindBillyBrown() routines look close to what you want.
