Excel Loop Through all filled cells in row 1 - excel

Question

I'm sure this is possible, im just not sure what the code should be. i have 2 sheets: (1)Component which has all the Component Names where an analyst got marked down on, including dates of when the call occurred, and (2)Calculator, which counts the number of times a specific component appeared in a specific week number.
ive created a code which gets the distinct Component Names from the Component Sheet, and then copies and transpose them to the Calculator sheet. all the Component Names are in Row 1 starting from Column D1 then goes to E1, F1, and so on. i want row 2 to display the count or the number of times the component(listed in row 1) appeared in a week.
The code i have only works for columns, i do not know how to make it get the non-empty values of an entire row.
'//here the code i used to transpose Distinct Components from the Component sheet to the Calculator Sheet
Public Sub GetDistinctComponents()
Application.ScreenUpdating = False
Dim lr As Long
lr = Sheets("Components Data").Cells(Rows.Count, "F").End(xlUp).Row
Sheets("Calculator").Unprotect Password:="secret"
Sheets("Components Data").Range("F1:F" & lr).AdvancedFilter Action:=xlFilterCopy, _
CopyToRange:=ActiveSheet.Range("DW1"), Unique:=True
With ThisWorkbook.Worksheets("Calculator")
.Range(.Range("DW1"), .Range("DW1").End(xlDown)).Copy
.Range("DX1").PasteSpecial xlPasteValues, Transpose:=True
.Columns("DW").EntireColumn.Delete
End With
Sheets("Calculator").Protect Password:="secret", DrawingObjects:=False
End Sub
Here's my Component sheet
And below is my Calculator sheet. as you can see, the code to transpose the distinct Components works fine. i just do not know how to get the value of Row 1 starting from DX so i can store it in a variable which i will use in counting the number of times that component appeared in a week . I'm thinking it should go like this
Component = wsCalculator.Cells(i, "D").Value
But this code only works if i want to get the Values of all cells in Column D, not the values of the cells next to D1
and here's the code i currently have
Public Sub CountComponent()
Application.ScreenUpdating = False
Sheets("Calculator").Unprotect Password:="secret"
Set wsComponentData = Sheets("Components Data")
Set wsCalculator = Sheets("Calculator")
Dim ComponentCount As Integer
'//Get the index of the last filled row based on column A
LastComponentRowIndex = wsComponentData.Cells(Rows.Count, "A").End(xlUp).Row
'//Get Range for ComponentData
Set ComponentRange = wsComponentData.Range("F2:F" & LastComponentRowIndex)
'//Get the index of the last filled row based on column C
LasttotalauditRowIndex = wsCalculator.Cells(Rows.Count, "C").End(xlUp).Row
'//Get range for Calculator
Set MyRange = wsCalculator.Range("C2:C" & LasttotalauditRowIndex)
TotalCalls = WorksheetFunction.Sum(MyRange)
'//Looping through all filled rows in the Components Data sheet
For i = 2 To wsCalculator.Cells(Rows.Count, "A").End(xlUp).Row
'//Get Component from cell in column "DW"
'Component = wsCalculator.Cells(i, "DW").Value
'//Count the # of calls that got hit in the corresponding Component
If wsCalculator.Cells(i, "DW").Value <> "" Then
ComponentCount = Application.WorksheetFunction.CountIf( _
ComponentRange, component)
wsCalculator.Cells(i, "DX").Value = ComponentCount
End If
Next
End Sub

I'll take a crack at this. I'm not 100% sure what you are doing, but I'm going to assume you will have soon calculations in cells D2, down, and to the right. Is that correct? Try this small code sample to copy from D2 (down and right) on the "Components Data" sheet, and transpose to your "Calculator" sheet.
Sub TransposeThis()
Set Rng = Sheets("Components Data").Range("D2:D7") 'Input range of all fruits
Set Rng_output = Sheets("Calculator").Range("B2") 'Output range
For i = 1 To Rng.Cells.Count
Set rng_values = Range(Rng.Cells(i).Offset(0, 1), Rng.Cells(i).End(xlToRight)) 'For each fruit taking the values to the right which need to be transposed
If rng_values.Cells.Count < 16000 Then 'To ensure that it doesnt select till the right end of the sheet
For j = 1 To rng_values.Cells.Count
Rng_output.Value = Rng.Cells(i).Value
Rng_output.Offset(0, 1).Value = rng_values.Cells(j).Value
Set Rng_output = Rng_output.Offset(1, 0) 'Shifting the output row so that next value can be printed
Next j
End If
Next i
End Sub

The code below is your own code, in part, which I commented, and of my own making for those parts where you seemed to have lost your way.
Public Sub CountComponent()
' Locations:-
Dim WsComp As Worksheet
Dim WsCalc As Worksheet
Dim CompRng As Range ' column A
Dim CalcRng As Range ' Calculator!D1:D?)
Dim Rt As Long ' Target row (in WsCalc)
' Helpers:-
Dim Cell As Range
Dim R As Long
Set WsComp = Sheets("Components Data")
Set WsCalc = Sheets("Calculator")
WsCalc.Unprotect Password:="secret"
Application.ScreenUpdating = False
'//Get the index of the last filled row based on column A
With WsComp
' observe the leading period in ".Rows.Count"
'LastComponentRowIndex = .Cells(.Rows.Count, "A").End(xlUp).Row
'//Get Range for ComponentData
'Set CompRng = .Range("A2:A" & LastComponentRowIndex)
' avoids the need for decalring LastComponentRowIndex
Set CompRng = .Range(.Cells(2, "A"), _
.Cells(.Rows.Count, "A").End(xlUp))
End With
With WsCalc
' set a range of all criteria to look up
Set CalcRng = .Range(.Cells(1, "D"), _
.Cells(1, .Columns.Count).End(xlToLeft))
'//Get the index of the last non-empty row in column B
' loop through all rows in WsCalc
For R = .Cells(.Rows.Count, "B").End(xlUp).Row To 2 Step -1
If Val(.Cells(R, "B").Value) Then ' presumed to be a week number
'//Loop through all audit criteria
For Each Cell In CalcRng
With .Cells(R, Cell.Column)
.Value = WorksheetFunction.CountIfs( _
CompRng, Cell.Value, _
CompRng.Offset(0, 1), WsCalc.Cells(R, "B").Value)
.NumberFormat = "0;-0;;" ' suppress display of zero
End With
Next Cell
End If
.Cells(R, "C").Value = WorksheetFunction.Sum(CalcRng.Offset(R - 1))
Next R
End With
Application.ScreenUpdating = True
End Sub
Frankly, I couldn't understand all of your intentions. I presumed that column B in your Calculations sheet would contain a week number and that this week number would also be found in the Components Data (in column B). If so, you would be counting the occurrences of each component by week, and that is what I programmed.
I think it doesn't matter if I got that part wrong. Your main question was how to look up each of the Components in Calculations!D1:??. That method is very well demonstrated in my above answer and I feel confident you will be able to transplant the useful bits to your own project. Good luck!

I suggest taking a look at VBA dictionaries. In this case, you could store each component as a key and for the value you can accumulate the number of occurrences of the component for a given week.
I don't have a VBA editor available on my computer at the moment to test this, but it would likely look something along the lines of what I've got below. Also, I'll admit that I may not have fully understood the layout of your sheets, but the general principle here will definitely apply.
For a pretty full overview of dictionaries in VBA, here's a good resource that'd I'd recommend: https://excelmacromastery.com/vba-dictionary/
Public Sub CountComponent()
Application.ScreenUpdating = False
Sheets("Calculator").Unprotect Password:="secret"
Set wsComponentData = Sheets("Components Data")
Set wsCalculator = Sheets("Calculator")
'//Get the index of the last filled row based on column A
LastComponentRowIndex = wsComponentData.Cells(Rows.Count, "A").End(xlUp).Row
'//Get Range for ComponentData
Set ComponentRange = wsComponentData.Range("A2:A" & LastComponentRowIndex)
'//Get the index of the last filled row based on column C
LasttotalauditRowIndex = wsCalculator.Cells(Rows.Count, "C").End(xlUp).Row
'//Get range for Calculator
Set MyRange = wsCalculator.Range("C2:C" & LasttotalauditRowIndex)
TotalCalls = WorksheetFunction.Sum(MyRange)
'// Declare a new dictionary
dim componentDict as New Scripting.Dictionary
'// First loop through the Calculator sheet to get each component
'// and set initial value to zero
dim i as Long, lastCalcColumn as Long
lastCalcColumn = wsCalculator.Cells(1, Columns.count).end(xlToLeft).Column
for i = 4 to lastCalcColumn
'// Adding each item to dictionary, a couple of ways to write this,
'// but this is probably the easiest
componentDict(wsCalculator.Cells(i, 1).Value) = 0
next i
'//Looping through all filled rows in the Components Data sheet
'// I changed this to loop through each row in your component sheet
'// So that we can accumulate the total occurences
dim current_key as String
For i = 2 To LastComponentRowIndex
If wsComponentData.Range("G" & i).Value <> "" Then
'// assuming component names are in the "G" column
'// change this as needed
current_key = wsComponentData.Range("G" & i).Value
componentDict(current_key) = componentDict(current_key) + 1
end if
Next i
'// now back to the Calculator sheet to enter the values
for i = 4 to lastCalcColumn
current_key = wsCalculator.Cells(i, 1).Value
wsCalculator.Cells(i, 2).Value = componentDict(current_key)
next i
End Sub
