i have a userform i fill doing a vlookup from a table. if the user changes
the record, how do i determine the row number the data was in to copy the
data back to the table?

Gary,

Copy the records to variant array before the user-change and the
re-copy same range into a second variant array. Next take th
differences between the two: changes will be reflected by zer
differences. It is inconsequential whether data is numeric
alphanumeric or whatever.


Illustration:

Dim v
Dim u

Before user effects changes:
'create 1st variant array
v=Range("a1:a100").value

After changes:
'create 2nd variant array
u=Range("a1:a100").value

'copy diffs to normal array
Dim dArray()
For i = 1 to Application.CountA([a:a])
Redim preserve dArray(1 to i)
dArray(i)= v(i,1)-u(i,1)
Next


'determine row nos where changes were made by setting dArray(x)= 0
For x = 1 to Application.CountA([a:a])
If dArray(x)= 0, then
k = k & "Row " & x & ":"
end if
Next

Msgbox k 'lists all rows wuth changes

End sub

kind of complicated for me to understand. i ended up just adding a rownumber
field and put it into a hidden textbox on the form. i have no idea what's
going on here now, because i did just about the same thing on my first form
programming, but every time i try to change and update a record, only the
first field changes.

but i think i have it now

Gary, why don't you just use MATCH against the first column of the lookup
data to get its index

myRow = Application.VLOOKUP(uf_val,Worksheets("Sheet1").Ra nge("A1:A100",0)

If the table does not start in row 1 do not forget to add the number of rows
preceding it as MATCH returns the index into the data not the row number.

David, I get a 'Type Mismatch' on the line:
dArray(i)= v(i,1)-u(i,1)

I don't see what it is.

Where Bob has
myRow = Application.VLOOKUP(uf_val,Worksheets("Sheet1").Ra nge("A1:A100",0)

should be

myRow = Application.Match(uf_val,Worksheets("Sheet1").Rang e("A1:A100"),0)

If you have non-numeric values in your range, you could get a type mismatch
error

ex in the immediate window:

? "A" - "B"

produces type mismatch.

Mike,

Tom was right. To cover both numeric and alphanumeric values, the
following modification is needed, making code all-purpose.

Sub FindRowChanges()
Dim v
Dim u

'populate range with 123abc
Range("a1:a100") = "123abc"
Range("a1:a100").Value = Range("a1:a100").Value

'create 1st variant array
v = Range("a1:a100").Value

'effect changes to a5 and a10
Range("a5") = 500
Range("a10") = 800

'After changes:
'create 2nd variant array
u = Range("a1:a100").Value

'check differences
For i = 1 To Application.CountA([a:a])
If Not v(i, 1) Like u(i, 1) Then
k = k & "Row " & i & ":"
End If
Next

MsgBox k 'lists all rows wuth changes

End Sub
