Excel VBA, nested loops / hide rows based on numbers - vba

Question

Dear stackoverflow community
At work I have to write a macro which should be able to hide rows based on numbers in a column. Those can be multiple ones in one cell and the input should also allow to show more than one number at a time.
for example:
row 1: 20, 30, 15
row 2: 20
row 3: 13, 76
So if I enter 20, 30, it should only show rows 1 & 2)
I usually code with Java / c# and Im new to VBA, so Id really appreciate help:
My plan was to show a input box and split those numbers into an array.
Then i wanna go through each row with a for-Loop, in which i added two for each loops to check if any numbers equal. If not, hide row. If so, show and then i want to exit both for each loops and go to the next row. To exit nested loops, i tried using a do while boolean but it doesnt seem to work.
Right now it only shows the rows with all the input numbers (only row1 in example).
Sub SortingTest()
Dim numbers() As String
myNum = Application.InputBox("Enter BKPS (separate multiples by , )")
numbers = Split(myNum, ",", -1, compare)
'Userinput Vars
Dim row As Integer
row = 1
Dim saveNumber As String
'Looping Vars
Dim existingNum As String
Dim existingNumsArray() As String
Dim checkRows As Long
Dim saveElement As String
Dim done As Boolean
done = False
' Range("B3").Value = 10
' Saves the Input as Array:
For Each Element In numbers
saveNumber = Element
Cells(2, row).Value = saveNumber
row = row + 1
Next Element
Dim b As Integer
Do While done = False
For b = 1 To 100 'hardcoded, should be length of document. b == row;
existingNum = Cells(b, 3).Value
existingNumsArray = Split(existingNum, ",", -1, compare)
' loop thru input numbers
For Each Element In numbers
saveElement = Element
'loop thru given numbers
For Each inputElement In existingNumsArray
If saveElement <> inputElement Then
Rows(b).Hidden = True
ElseIf saveElement = inputElement Then
Rows(b).Hidden = False
done = True
Exit For
End If
Next
Next
Next
Loop
End Sub

Answer 1

Thank you very much for you answer. Yours hid all the rows, so i adjusted it to show them.
Option Explicit
Function ArrOr(a As Variant, b As Variant) As Boolean
Dim runner As Variant
ArrOr = True
If IsArray(a) Then
For Each runner In a
If ArrOr(runner, b) Then Exit Function
Next
Else
For Each runner In b
If Trim(a) = Trim(runner) Then Exit Function
Next
End If
ArrOr = False
End Function
Sub SortingBKPS()
Dim numbers As Variant, vars As Variant, i As Long, xRows As Range
numbers = Split(Application.InputBox("Enter BKPS (separate multiples by , )"), ",")
With Sheets("Sheet1")
vars = .Range("B1", .Cells(.Rows.Count, 2).End(xlUp)).Value2
For i = 2 To UBound(vars)
.Rows(i).EntireRow.Hidden = True
If ArrOr(Split(vars(i, 1), ","), numbers) Then
If xRows Is Nothing Then
Set xRows = .Rows(i)
Else
Set xRows = Union(xRows, .Rows(i))
End If
End If
Next
xRows.EntireRow.Hidden = False
End With
End Sub

Answer 2

By splitting it up it is very easy to do:
Option Explicit
Function ArrOr(a As Variant, b As Variant) As Boolean
Dim runner As Variant
ArrOr = True
If IsArray(a) Then
For Each runner In a
If ArrOr(runner, b) Then Exit Function
Next
Else
For Each runner In b
If Trim(a) = Trim(runner) Then Exit Function
Next
End If
ArrOr = False
End Function
Sub SortingTest()
Dim numbers As Variant, vars As Variant, i As Long, xRows As Range
numbers = Split(Application.InputBox("Enter BKPS (separate multiples by , )"), ",")
With Sheets("Sheet1")
vars = .Range("B1", .Cells(.Rows.Count, 2).End(xlUp)).Value2
For i = 1 To UBound(vars)
If ArrOr(Split(vars(i, 1), ","), numbers) Then
If xRows Is Nothing Then
Set xRows = .Rows(i)
Else
Set xRows = Union(xRows, .Rows(i))
End If
End If
Next
xRows.EntireRow.Hidden = True
End With
End Sub
by running this code line by line, it should be pretty much self explaining (also knowing you have already some knowledge in "coding")
Still, if you have any questions, just ask ;)

You can also do it the following way:
Sub SortingTest()
Dim numbers As Variant
Dim RangeCompare As Range
Dim MyRow As Integer
Dim NumFound As Boolean
numbers = Application.InputBox("Please,list the values in this format: " & _
vbCrLf & "{value, value, value, ...}", _
Default:="{#, #, #}", Type:=64)
For MyRow = 1 To Cells(Rows.Count, 1).End(xlUp).row
Set RangeCompare = Range(Cells(MyRow, 1), Cells(MyRow, Columns.Count).End(xlToLeft))
NumFound = False
For Each rCell In RangeCompare
For Each Element In numbers
If rCell = Element Then
NumFound = True
Exit For
End If
Next Element
If NumFound = True Then Exit For
Next rCell
If NumFound = False Then
Rows(MyRow).Hidden = True
End If
Next MyRow
End Sub
I think it's easy to understand but feel free to ask for explanation.
