Count Number of Rows based on Parameter. (Excel VBA) - vba

I need to count the number of rows depending on the week and type of the data. I have the excel formula but I want to make it as a VB code yet I don't have that much idea and it is not working.
=IF(AND($N$4="All",$N$5="All"),SUM(('SD'!$I$2:$I$99538='Source'!$B6)*('SD'!$A$2:$A$99538='Source'!C$5)),IF(AND($N$4="All",$N$5<>"All"),SUM(('SD'!$I$2:$I$99538='Source'!$B6)*('SD'!$A$2:$A$99538='Source'!C$5)*('SD'!$B$2:$B$99538='Source'!$N$5)),IF(AND($N$4<>"All",$N$5="All"),SUM(('SD'!$I$2:$I$99538='Source'!$B6)*('SD'!$A$2:$A$99538='Source'!C$5)*('SD'!$K$2:$K$99538='Source'!$N$4)),IF(AND($N$4<>"All",$N$5<>"All"),SUM(('SD'!$I$2:$I$99538='Source'!$B6)*('SD'!$A$2:$A$99538='Source'!C$5)*('SD Raised'!$B$2:$B$99538='Source'!$N$5)*('SD'!$K$2:$K$1048576='Source'!$N$4))))))
I have a sheet where in all datas are captured (SD) and the second one will be the sheet(Source) where i need to count the number of rows available based on the parameter as follow; The week where data belongs and the category of the data.
Edit:
This formula* does not count the data i needed to count. And if possible I want to make it as a VBA code.
This is where the counted data should go. "Weeks are changing depending on the dropdown iput (Max of 4 weeks below from the selected week)"
This image shows the data where i need to capture and count the number of category based on the weeks and category. (Sample only)

I guess, if it's the right point you're hitting DoktorOSwaldo, better use the Range().Rows.Count property rather than scrolling through allRows.
Hope this helps.

so i have to guess a bit what you want, but if you want to Count specific rows in Excel vba you can use something like this:
Dim allRows As Variant
Dim i As Long
Dim count as Long
count = 0
allRows = Tabelle5.Range("A" & start_row, end_column & last_row)
For i = 1 To UBound(allRows)
If allRows(i, 1) = *category* and allRows(i,2) = *week* Then
count = count + 1
End If
Next
To find right range, there are multiple possible solution. I use this, maybe it is not the best, but works fine for me:
Private Function last_row() As Integer
Dim rangeObj As Range
Set rangeObj = Tabelle5.Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious)
If rangeObj Is Nothing Then
last_row = start_row
Else
last_row = rangeObj.row
End If
End Function
Public Function start_row() As Integer
start_row = 2
End Function

VBA: Syntax for dynamic CountIf Ranges

I'll do my best to try and explain my problem, but it's still a bit fuzzy in my mind so this might not be as clear as it should be, for which I apologize in advance.
Here's the part of my code I'm having trouble with:
If Application.WorksheetFunction.countif(Range("D:D"), Cells(x, firstcolumn).Value) _
And Application.WorksheetFunction.countif(Range("F:F"), Cells(x, firstcolumn).Value) _
And Application.WorksheetFunction.countif(Range("H:H"), Cells(x, firstcolumn).Value) Then
The idea behind this project is to check if the values in "Cells(x, firstcolumn)" are present in columns D, F and H at the same time, and then paste the values somewhere else.
However the number of columns to check for the "Cells(x, firstcolumn)" values could be changed, so values would need to be checked in any number of columns (2, 10 etc). My code works perfectly for the specified Ranges but if one is missing or more are added then it stops working.
The columns to check against are always offset by 2 from the firstcolumn and firstcolumn is always B, it will be checked against D, F, H and so on while columns C,E,G etc have other data not relevant for this part.
My best guess is to have the countif Ranges changed dynamically but I'm at a loss of when and how this should be done...
Could anyone point me towards the right direction in order to achieve this? I can post the full code if needed.
Cheers!
You need to extract a function here. Something like this:
Private Function IsPresentInRange(ByVal source As Range, ByVal value As Variant) As Boolean
IsPresentInRange = Application.WorksheetFunction.CountIf(source, value) > 0
End Function
And then you need a way to figure out what ranges you need to give it for a source parameter - that can be a function of its own, or you can hard-code them somewhere; basically you want to have a concept of a group of ranges to call that function with - this would be the simplest:
Private Function GetSourceRanges() As Collection
Dim result As New Collection
result.Add Range("D:D")
result.Add Range("F:F")
result.Add Range("H:H")
'maintain this list here
Set GetSourceRanges = result
End Function
Ideally you would have some logic coded there, so that you don't need to manually add ranges to that collection every time.
And then you can just iterate these ranges and determine if you get a count > 0 for all of them:
Dim sources As Collection
Set sources = GetSourceRanges
Dim result As Boolean
result = True
Dim sourceRange As Range
For Each sourceRange In sources
result = result And IsPresentInRange(sourceRange, Cells(x, firstcolumn).Value)
Next
If result Then
' whatever you had in that If block
End If

VBA - merge set number of rows in first column

I have seen some VBA examples on here allowing one to merge set numbers of cells, but none exactly as I need it.
What I would like to do is go down the entire column A:A and merge every four rows, starting with cell A4. I know this involves changing the reference cell but I'm not skilled enough with the language to know how to do this without screwing up the cycle.
Here is an example of the data I would like to format. Thanks in advance for any and all help with this.
Simply set Count to the number of merged cells that you want and run the MergeColA.
Sub MergeColA()
Dim Count As Integer
Count = 10
MergeCells (Count)
End Sub
Sub MergeCells(Count As Integer)
For i = 4 To 4 * count Step (4)
Dim r As Range
Set r = Range("A" & i, "A" & i + 3)
r.Merge
Next i
End Sub

Macro to run through 3 conditions and provide value

This is my first time using VBA for Excel (I usually code Java and C++), and I was hoping to get some tips to start out.
I want to write a macro for a large data set that will proceed through the following list of conditions to provide a dollar result:
Collect unit size from column A (Possible values 0-8)
Determine whether single or family unit from Column B (Single- 1, Family- 0)
Collect utility code from Column C (code for type of product being assessed)
From this information, a new value will be placed in the row which determines utility costs by taking into account unit size, type of unit, and the product in question. I have thought about using nested Select Case or nested conditionals in a loop, but overall I am pretty lost.
It seems like a worksheet formula might do the trick, but it's hard to tell without knowing what the calculation is. Below is a user-defined function (UDF) that you would put in a standard module. You would call it from a cell like:
=computecosts(A2,B2,C2)
Obviously the code would change depending on how your data is laid out and what your calculation is.
Public Function ComputeCosts(rSize As Range, rFamily As Range, rCode As Range) As Double
Dim lSizeFactor As Long
Dim lFamilyFactor As Long
Dim dCodeFactor As Double
Dim rFound As Range
Const lFAMILY As Long = 0
'Size factor is a function of 0-8, namely adding 1
lSizeFactor = rSize.Value + 1
'Family factor is computed in code
If rFamily.Value = lFAMILY Then
lFamilyFactor = 3
Else
lFamilyFactor = 2
End If
'Code factor is looked up in a different sheet
Set rFound = Worksheets("Sheet2").Columns(1).Cells.Find(rCode.Value, , xlValues, xlWhole)
If Not rFound Is Nothing Then
dCodeFactor = rFound.Offset(0, 1).Value
End If
'do the math
ComputeCosts = lSizeFactor * lFamilyFactor * dCodeFactor
End Function
Thanks for the responses, they were helpful in understanding VBA for Excel. I just ended up putting possible values in a table and then using Match functions within an Index function to pick out the right value.

Excel VBA - Compare worksheet rows based off of value

Similar issue to these:
Find the differences between 2 Excel worksheets?
Compare two excel sheets
My issue specifically, I have a monthly employee listing with a unique ID and around 30 columns of other data for around 900 employees.
I'm trying to accomplish two things:
Compare if employees were added or dropped between the lists.
Between the sheets for each employee compare what other data for that employee changed. i.e. Job Title changed.
Most compare add-ins/modules I find only compare the specific ranges in order, thus once once difference if found every subsequent row will be different.
First, I'm wondering if there are any existing tools that can do this. If not I was thinking of building my own. I was thinking of doing this by looping through each employee and using vlookup to verify matches. I'm concerned doing this many loops will make the macro difficult to use. Any guidance on how I should go about this? Thanks.
Untested, but will give you a place to start from...
This does not find ex-employees which are on the "old" sheet but not on the "current" sheet.
Sub CompareEmployeeInfo()
Const ID_COL As Integer = 1 ' ID is in the first column
Const NUM_COLS As Integer = 30 'how many columns are being compared?
Dim shtNew As Excel.Worksheet, shtOld As Excel.Worksheet
Dim rwNew As Range, rwOld As Range, f As Range
Dim x As Integer, Id
Dim valOld, valNew
Set shtNew = ActiveWorkbook.Sheets("Employees")
Set shtOld = ActiveWorkbook.Sheets("Employees")
Set rwNew = shtNew.Rows(2) 'first employee on "current" sheet
Do While rwNew.Cells(ID_COL).Value <> ""
Id = rwNew.Cells(ID_COL).Value
Set f = shtOld.UsedRange.Columns(ID_COL).Find(Id, , xlValues, xlWhole)
If Not f Is Nothing Then
Set rwOld = f.EntireRow
For x = 1 To NUM_COLS
If rwNew.Cells(x).Value <> rwOld.Cells(x).Value Then
rwNew.Cells.Interior.Color = vbYellow
Else
rwNew.Cells.Interior.ColorIndex = xlNone
End If
Next x
Else
rwNew.Cells(ID_COL).Interior.Color = vbGreen 'new employee
End If
Set rwNew = rwNew.Offset(1, 0) 'next row to compare
Loop
End Sub
Don't know if there is anything that does that for you or not. But, you can use the Dictionary Object to make this comparison task much easier. You can also take examples from this answer that uses Dictionaries which checked for uniques and is optimized for speed, change it to what you need. Then you can use this fast method to color the cells or whatever you want to do with it.
I know I'm not providing code for you but these pointers will get you started, and if you have more questions I can help you out.

Functions not actualizing

I execute a VBA code that takes a database, treats it and export it into a sheet. This is working fine. However, I have a sheet that produces graphs depending on the data in the particular sheet. The datas does not actualize. I have to enter the cell and click enter to actualize it. I'm pretty sure there is an easier way to do this. Calculation is set to automatic but that doesn't seem to change anything.
In my cell, I have my own vba function that needs to be updated once the report is done. When I click the cell and then enter, the result is updated but I would like this to be done automatically. I hope this is clearer !
Thanks in advance,

HEre is the code of my function
Public Function number_of_appearances(term As String, sheet As String, column As Integer) As Integer
Application.Volatile
Dim number_of_rows As Integer
Dim appearances As Integer
Dim row As Integer
appearances = 0
row = 1
number_of_rows = Worksheets(sheet).UsedRange.Rows.Count
Do While row <= number_of_rows
If Worksheets(sheet).Cells(row, column).Value = term Then
appearances = appearances + 1
End If
row = row + 1
Loop
number_of_appearances = appearances
End Function
A cell example of a user of the function
=number_of_appearances('test';'sheet1'; 3)
Sounds like your UDF might not depend on any cells that change value when your DB is processed.
See This MSDN Link
Post your UDF (or just its header if you prefer) and an example of its use...
EDIT:
Yes, none of the parameters to the UDF are cell references, therefore the UDF is not triggered to recalculate when data on the shet changes.
You have two choices:
1. rewrite your UDF to include parameter(s) that reference cells that change value when the DB is processed
2. make your UDF volitile (include Application.Volatile in the UDF code) WARNING: this can be very inefficient, depending on how many time the UDF is used and how intensive its calculation is
EDIT 2:
Heres a refactor of your udf using the first option mentioned:
Public Function number_of_appearances(term As String, rng As Range) As Integer
Dim v As Variant
Dim i As Long, j As Long
Dim appearances As Long
v = Intersect(rng, rng.Worksheet.UsedRange)
For j = LBound(v, 2) To UBound(v, 2)
For i = LBound(v, 1) To UBound(v, 1)
If v(i, j) = term Then
appearances = appearances + 1
End If
Next i, j
number_of_appearances = appearances
End Function
use like
=number_of_appearances("test";Sheet1!C:C)
EDIT 3:
If all you are doing is counting number of occurances of a string in a range, consider using
=COUNTIF(Sheet1!C:C;"test")
