Passing an Matrix (?) to VBA in Excel
Question
one common solution in Excel to SUMIF() with multiple conditions goes like this (this formula counts all cases in which column A has the value in C1 and column B has the value in D1):
=SUMPRODUCT((A1:A9=C1)*(B1:B9=D1))
I, now, need a function that concatenated strings from lines fulfilling multiple conditions. There is a great solution for one condition at http://www.ms-office-forum.net/forum/showthread.php?t=273352
I, however, want to check multiple conditions - and therefore use the SUBPRODUCT() trick from above. My problem is: How do I have to define the parameter in the function to get an Array? This is what I got so far:
' **********************************************************************
' Modul: Modul1 Typ: Allgemeines Modul
' **********************************************************************
Option Explicit
Public Function CONCATIF(Kriterium, Inhalte)
Dim mydic As Object
Dim L As Long
Set mydic = CreateObject("Scripting.Dictionary")
For L = 1 To UBound(Kriterium)
If Kriterium(L, 1) = 1 Then
If Inhalte(L, 1) <> "" Then
mydic(L) = Inhalte(L, 1)
End If
End If
Next
CONCATIF = Join(mydic.items, vbCrLf)
End Function
This works fine, if I select one columns for parameter 1. But as soon as I include a product formula (like above), only a Variant/Double with the value 1 is passed for Kriterium.
=CONCATIF(A1:A9; E1:E9) Works fine (if column A is 0/1 coded)
=CONCATIF((A1:A9=C1)*(B1:B9=D1); E1:E9) Does not work at all
Any suggestions? Thank you!
Solution
The problem was because formula:
=CONCATIF((A1:A9=C1)*(B1:B9=D1); E1:E9)
need to be called by pressing CTRL+SHIFT+ENTER
OTHER TIPS
For the sake of completeness, here's the complete Excel VBA Macro to concatenate strings from a range (may have multiple string columns), if criteria in other columns are matched.
' **********************************************************************
' Modul: Modul1 Typ: Allgemeines Modul
' **********************************************************************
Option Explicit
Public Function CONCATIF(Kriterium, Inhalte)
Dim mydic As Object
Dim L As Long
Dim C As Long
Dim N As Long
Dim cols As Long
Set mydic = CreateObject("Scripting.Dictionary")
cols = Inhalte.Columns.Count
N = 1
For L = 1 To UBound(Kriterium)
If Kriterium(L, 1) = 1 Then
For C = 1 To cols
If Not IsEmpty(Inhalte(L, C)) Then
mydic(N) = "* " & Inhalte(L, C)
N = N + 1
End If
Next
End If
Next
CONCATIF= Join(mydic.items, vbCrLf)
End Function
Use as follows - and don't forget to enter by CTRL+SHIFT+ENTER
=CONCATIF((A1:A:9="male")*(B1:B9="young"); C1:D9)
