List all unique values based on criterias - arrays

Question

I need to list all values that have a specific criteria in other columns as shown
I have the following:
Sub arytest()
Dim ary()
Dim note2()
Dim lastrow As Long
Dim i As Long
Dim k As Long
Dim eleAry, x
'Number of rows in my data file
lastrow = Sheet2.Cells(Sheet2.Rows.Count, "A").End(xlUp).Row
'The maximum length of my array
ReDim ary(1 To lastrow)
k = 1
For i = 1 To lastrow
If Cells(i, 2) Like "*Note 2*" _ ' Criterias that needs to be fullfilled
And Cells(i, 1) Like "Actuals" _
And Cells(i, 4) Like "Digitale Brugere" Then
ary(k) = Cells(i, 3)
k = k + 1
End If
Next i
End Sub
This code lists all values I need. However some of them are present multiple times. How can I remove duplicates?

Answer 1

Here is another way, so you won't need to remove duplicates later, using Scripting Dictionary (you need to check the Microsoft Scripting Runtime on the libraries for this to work)
Sub arytest()
Dim ary()
Dim note2() 'unsued
Dim lastrow As Long
Dim i As Long
Dim k As Long
Dim eleAry, x 'unused
Dim DictDuplicates As Scripting.Dictionary
Set DictDuplicates = New Scripting.Dictionary
'Number of rows in my data file
lastrow = Sheet2.Cells(Sheet2.Rows.Count, "A").End(xlUp).Row
'The maximum length of my array
ReDim ary(1 To lastrow)
k = 1
For i = 1 To lastrow
' Criterias that needs to be fullfilled
If Cells(i, 2) Like "*Note 2*" _
And Cells(i, 1) Like "Actuals" _
And Cells(i, 4) Like "Digitale Brugere" Then
If Not DictDuplicates.Exists(Cells(i, 3).Value) Then 'check if the value is already on the array
ary(k) = Cells(i, 3)
DictDuplicates.Add Cells(i, 3).Value, i 'if it does not exists, add it to the dictionary
End If
k = k + 1
End If
Next i
End Sub
I've also seen some variables unused on your code, or at least what you posted.
PS: when using the Likeoperator you should use the wildcards* or ?, without them is the same as if you were using the = operator.
