Multidimensional Array

I have a multidimensional array that is 6 colums wide.

I am populating it from a recordset and therefore do not know the length so I using a dynamic array as below

currentfile = 0
WHILE NOT MyRS2.EOF
      IF currentfile = 0 Then
      ' do nothing
      Else
      Redim Preserve ArrPassed(5,currentfile)
      End IF
      ArrPassed(vantivenumber,currentfile) = MyRS("vantivenumber")
      ArrPassed(teamname,currentfile) = MyRS("teamname")
      ArrPassed(passedreason,currentfile) = MyRS("passedreason")
      ArrPassed(timetaken,currentfile) = MyRS("timetaken")
      ArrPassed(notes,currentfile) = MyRS("notes")
      ArrPassed(dateentered,currentfile) = MyRS("dateentered")
      currentfile = currentfile + 1
MyRS2.MoveNext
Wend

I am now trying to find out how to find out the ubound limits of the array so i can do a for next loop but i cant seem to figure it out from the many articles i have read.

This is extremely urgent hence the points.

Hi

have you tried UBound(ArrPassed)

That should work ok

You could always switch your array around so your code snippet becomes

currentfile = 0
WHILE NOT MyRS2.EOF
     IF currentfile = 0 Then
     ' do nothing
     Else
     Redim Preserve ArrPassed(currentfile,5)
     End IF
     ArrPassed(currentfile,vantivenumber) = MyRS("vantivenumber")
     ArrPassed(currentfile,teamname) = MyRS("teamname")

and so on

UBound(arrayname[, dimension])

Ubound(ArrPassed,1)
Ubound(ArrPassed,2)


Example:

Dim A(1 To 100, 0 To 3, -3 To 4)


UBound(A, 1) ---> 100
UBound(A, 2) ---> 3
UBound(A, 3) ---> 4

to get the UBound of the 2nd dimension use the following:

UBound(ArrPassed, 2)

PS: You could dimension the array(Rows, Columns) rather than (Columns, Rows)
      then UBound without the dimension parameter would work.

UBound(arrayname[, dimension])

The UBound function syntax has these parts:

arrayname: Required. Name of the array variable; follows standard variable naming conventions.

dimension: Optional; Variant (Long). Whole number indicating which dimension's upper bound is returned. Use 1 for the first dimension, 2 for the second, and so on. If dimension is omitted, 1 is assumed.

You could also Dim the array to begin indexing at 1 not 0:

Dim array(1 To 10)
Dim multiarray(10, 1 To 10)
0

Sorry guys, my mistake.

The problem was the recorset was EOF and this was the one time i didnt test for it. seen as the array didnt complain i presumed the data was in there.

All the information given was good and similar to what i have already read.

Ill split the points for your quick responses and grade accordingly.
