I want to count the unique values of a column therefor I first used a autofilter to get the correct rows that I want to advanced filter.
The result I've assigned to a range using
intersect(Used.range,range.specialcells(xlCellTypeVisible))
This gave me a range say (B10:B20, B75) so it's actually 2 ranges B10:B20 and B75. Therefor I cannot directly apply a advancedfilter on it. Does someone know how to do achieve this?
I've thought of splitting the range into two seperates but then I cannot count the unique values correctly, I'll get a count of one range and a count of the other but it's possible that they have the same values. I've also thought to put the values in a array, but it's not a very efficient way to do it I think.
Thanks.
Advanced Filter is not required if you only need a count of the filtered uniques.
Consider:
Sub Xepos()
Dim N As Long, c As Collection
Dim colid As String, r As Range
colid = "A"
Set c = New Collection
N = Cells(Rows.Count, colid).End(xlUp).Row
On Error Resume Next
For i = 2 To N
Set r = Cells(i, colid)
If r.EntireRow.Hidden = False Then
v = r.Text
c.Add v, CStr(v)
End If
Next i
MsgBox c.Count
End Sub
This assumes that the column is column A and there is a header cell in A1

I have a list of values mentioned in a column. i want to use vba to pick x number of values from that list.the number x is mentioned in another cell. can you help me?
i have tried various formulas but no solution.
assuming myColumnRng is your range of cells in a columns containing your list of values, you can get its first N elements in a Variant array as follows:
myElements = Application.Transpose(myColumnRng .Resize(nElements).Value)
to give a little bit more of context:
Option Explicit
Sub main()
Dim myColumnRng As Range
Dim myElements As Variant
Dim iEl As Long
Set myColumnRng = Range("A1", Cells(Rows.count, "A").End(xlUp)) '<--| set your range as the column "A" one from row 1 down to last not empty row
myElements = Application.Transpose(myColumnRng .Resize(nElements).Value)
For iEl = 1 To UBound(myElements)
Debug.Print myElements(iEl)
Next
End Sub
Pick x values on random, or pick first x values in the list?
I'm a newbie to VBA/coding in general and my usual tactic of sticking bits of pre-written code isn't working for my problem.
I'm looking to create a macro that will do 3 things:
Allow me to find a starting point for the data in a column.
Start counting the number of rows once the cell value has
changed to a constant.
Once the value moves back to the starting point for the count to stop and record the number of cells counted in separate column with positioning of the count in that column at the start point of the count.
Repeat until the end of the data.
For this case the start point will be when the cell has a value of >0.
It will increase to a constant number (300).
Once at 300 the macro will have to count the number of rows that contain the numerical value 300 until the value goes back to 0.
Report count in a separate table on the worksheet with the entry being input at the same relative position in the new table as when the count started from the data.
And finally the loop.
I need to also do a similar count but in the horizontal direction (i.e. counting columns on a row). If anyone can create a code for the vertical/row count problem above I'd really appreciate it if you could annotate it so I can attempt to understand/learn which bits of code carry out each action and thus change it up for horizontal/column count.
I've attached a screenshot of the spreadsheet however as a new user it must be as a link. The blue highlighted table is the data used for the vertical /row count problem I am talking about. The blank table underneath the highlighted table has manually inputted correct answers for the first column of data for what I would like the macro to do in case I haven't accurately described my request.
I have also attached the horizontal table with correct manually inputted answers for row 1 in the separate table for the column count along the row.
Lastly, here is the code that I have written to tackle the problem, however it is very basic and won't run.
Sub Count0()
For Each c In Worksheets("Sheet1").Range("D30:D39")
If c.Value = 0 Then
End If
If c.Value > 0 Then
v = Range(c.Value)
For i = 3 To Rows.Count
If Cells(i, 1).Value <> v Then
MsgBox CStr(i - 2)
End If
Next i
Next c
End Sub
This worked in the limited case I tested (two columns and several rows in different patterns. It's pretty basic--there are more elegant ways to do it.
Sub Count0()
'To hold the current cell
Dim current As Range
'To hold the total number of rows and columns having data
Dim rows As Long
Dim cols As Long
'To iterate across rows and columns
Dim r As Long
Dim c As Long
'Flag/counter variables
Dim found As Long 'Saves row on which first "constant" was found
Dim count As Long 'Saves count of "contants"
'Use SpecialCells method to obtain the maximum number of rows and columns
' that have data.
cols = Worksheets("Sheet1").Cells.SpecialCells(xlCellTypeLastCell).Column
rows = Worksheets("Sheet1").Cells.SpecialCells(xlCellTypeLastCell).Row
'Increment through all columns that have data. This is a bit inefficient
' because it really isn't necessary to go through all the empty cells,
' but it works.
For c = 1 To cols
'Initialize flag/counter
found = 0
count = 0
'Increment through all rows for the current column.
For r = 1 To rows
'Examine the current cell
Set current = Worksheets("Sheet1").Cells(r, c)
'For positive values, save the first row that has the value
' and count the number of values.
If current.Value > 0 Then
If found = 0 Then found = r
count = count + 1
End If
'When the next non-positive value is reached--OR the end of the
' row is reached--and there was a constant found, write the count
' to the next worksheet in the cell corresponding to the row and
' column having the first instance of the constant.
If (current.Value <= 0 Or r = rows) And found > 0 Then
Worksheets("Sheet2").Cells(found, c).Value = count
'Reset the flag/counter
found = 0
count = 0
End If
Next r
Next c
End Sub
I was struggling with what you had written, and ended up doing this in the end. I left you variables for changing the sheets to read from and print to (assuming you can print the results to another sheet- if not it should be easy enough to change).
This should also work for all cells in your range, assuming that there are values in all boxes.
Problems I noted with your original code were:
The first if did nothing
I'm pretty sure you shouldn't use numbers in sub/function names
Dimensioning no variables is a bad idea
Anyway, give me a comment if you need any help (and well done for writing a good first question).
Sub CountZero()
Dim SourceSheet As Worksheet, SummarySheet As Worksheet
Dim CurrentCell As Range
Dim FirstRow As Long, LastRow As Long
Dim FirstColumn As Long, LastColumn As Long
Dim TotalValues As Long
Set SourceSheet = Worksheets("Sheet1")
Set SummarySheet = Worksheets("Sheet2")
FirstRow = 1
LastRow = SourceSheet.Range("A" & rows.count).End(xlUp).row
FirstColumn = 1
LastColumn = SourceSheet.Cells(1, Columns.count).End(xlToLeft).column
For col = FirstColumn To LastColumn
For Rw = FirstRow To LastRow
Set CurrentCell = SourceSheet.Cells(Rw, col)
If CurrentCell <> 0 Then
TotalValues = ProcessSection(CurrentCell)
SummarySheet.Cells(Rw, col).value = TotalValues
Rw = Rw + TotalValues
End If
Next Rw
Next col
End Sub
Function ProcessSection(FirstCellWithValue As Range) As Long

As a small disclaimer, I haven't tested this, let me know if there are problems.
I've been working on a user-defined function in VBA to find a certain count. For background, "raw" is a worksheet that refers a sheet that has genres in column B and an artist ID in column C. The sheet that I'm working in has combinations of two genres: first in column A, second in column B.
Anyway, the function that I'm trying to build should do the following:
Take two inputs as strings. Check the genre column in "raw" for matches with the first input. Then, take that ID and find a cell that matches the ID and the second input. If there is one found, add one to a running count. Whether or not it is found, move onto the next match. The function will return an integer that indicates the number of times the two genres had the same artist ID.
Now, my function is returning #VALUE.. no syntax errors, no compiling errors. Just the error in returning the value. I've looked it over, googled like crazy, and I just can't figure it out. I'm new to VBA, so maybe I'm just missing something really obvious or I've defined something wrong. Either way, I just need another set of eyes to look over it. Any suggestions for improvement are much appreciated, so thank in advance for your time and help!!
Here is the code. I know it isn't the prettiest, but it's short and the logic should make sense.
Public Function cocount(c1 As String, c2 As String) As Integer
Dim rng As Range
Dim rng2 As Range
Dim cell As Range
Dim cell1 As Range
Dim ID As Integer
Dim Count As Integer
rng = Worksheets("Raw").Range("B2:B183579")
rng2 = Worksheets("Raw").Range("C2:C183579")
Count = 0
For Each cell In rng
If cell.Value = c1 Then
ID = cell.Offset(0, 1).Value
For Each cell1 In rng2
If cell1.Value = ID And cell1.Offset(0, -1).Value = c2 Then
Count = Count + 1
End If
Next cell1
End If
Next cell
cocount = Count
End Function
EDIT: Thanks for viewing my question and being willing to help (And thanks Rdster for attempting a solution). I uploaded pictures of the raw data and the combination, although it won't let me embed the images. Raw Data Combination List
Anyway, I'll try and explain my problem again. In the combination list of genres, each row contains two genres. I want to find how many times those two genres share the same artist ID in the Raw Data sheet. There are 181,000+ combinations, and 183,000+ rows in the Raw Data. Thus, the function needs to be efficient--something that I'm not incredibly great at doing even in other languages.
This can be achieved using built-in several different Excel Worksheet functions.
Excel Formula using COUNTIFS
Define 2 dynamic named ranges that will resize themselves to fit the data. Gendre_2 is defined relative to Gendre_1 this ensures that the ranges are the same size.
Gendre_1 = OFFSET(Raw!$A$1,1,0,COUNTA(Raw!$A:$A)-1,1)
Gendre_2 = OFFSET(Raw!$A$1,1,1,COUNTA(Raw!$A:$A)-1,1)
Formula
=COUNTIFS(Gendre_1,A2,Gendre_2,B2)
Reference: ExcelJet - Excel COUNTIFS Function
COUNTIFS counts the number of cells in a range that match supplied criteria. Unlike the COUNTIF function, COUNTIFS can apply more than one set of criteria, with more than one range. Ranges and criteria are applied in pairs, and only the first pair is required. For each additional criteria, you must supply another range/criteria pairs. Up to 127 range/criteria pairs are allowed.
VBA
Public Function cocount(c1 As String, c2 As String) As Double
Dim rng As Range, rng2 As Range
With Worksheets("Raw")
Set rng = .Range("A2", .Range("A" & .Rows.Count).End(xlUp))
Set rng2 = rng.Offset(0, 1)
cocount = WorksheetFunction.CountIfs(rng, c1, rng2, c2)
End With
End Function
If I understand correctly, you are trying to count the number of times that c1 and c2 = B# and C# where # is the same row.
Public Function cocount(c1 As String, c2 As String) As Integer
Dim Count As Integer, iRow as Integer
Count = 0
For iRow = 2 to Sheets("Raw").Cells(Rows.Count, "B").End(xlUp).Row
If Cells(iRow, "B") = c1 And Cells(iRow,"C") = c2 Then
Count = Count + 1
End If
Next iRow
cocount = Count
End Function
Check the genre column in "raw" for
matches with the first input. Then, take that ID and find a cell that
matches the ID and the second input.
try this:
Public Function cocount(FirstKey$, SecondKey$, FirstRng As Range, SecondRng As Range) As Long
Dim FirstAccurance As Range, ID$
Set FirstAccurance = FirstRng.Find(FirstKey, , xlValues, xlWhole, xlByRows, xlNext, 0)
ID = Cells(FirstAccurance.Row, SecondRng.Column).Value2
cocount = WorksheetFunction.CountIfs(SecondRng, ID, FirstRng, SecondKey)
End Function
test:
So I have a range that will be selected by a user. It will be two columns, usually not next to each other. I need to count the number of cells in each column of the selected range to determine if the number of cells in each column is equal. (If it's not I will need to adjust the range.)
For example, a User may select B5:B10 and D6:D9. So I need the code to return 6 and 4 respectively.
I've tried:
Set rng = Selection
rng.Columns(1).Count
this returns 1, which obviously isn't the number I need.
Thanks in advance!
You can use the Areas method of the Range object to get the areas of the range. Areas are groups of contiguous ranges within a non-contiguous range.
Set rng = Selection
For i = 1 to rng.Areas.Count
debug.print rng.Areas(i).Cells.Count
Next
There is caveat here that you may need to test for, and that is if the user selects, for example, A1:B10, with one mouse drag. Since this is a contiguous range, it will only have one Area and you will not get two distinct numbers. If you need to test for this, you can do something like the below.
Set rng = Selection
'non-contiguous ranges will always return one column, if there are mutiple columns both cell counts are equal by default
If rng.Columns.Count = 1 Then
For i = 1 to rng.Areas.Count
debug.print rng.Areas(i).Cells.Count
Next
End If
Dammit #Scott - just beat me to it.
Although I'm using the Rows property - if the user selects A1:B19 it will return 19 in a single element of the array, if they select A1:A19 and then B1:B19 it will return 19 in two elements of the array.
Using Cells it will return 38 in a single element, or 19 in two elements.
Sub Test()
Dim rRange As Range
Dim lRows() As Long
Dim x As Long
Set rRange = Selection
With rRange
ReDim lRows(1 To .Areas.Count)
For x = 1 To .Areas.Count
lRows(x) = .Areas(x).Rows.Count
Next x
End With
End Sub
Ok I have tried these and grasped some view on variants and I have written these code
Sub main()
Dim Vary As Variant
Vary = Sheet1.Range("A1:D11").Value
For i = 1 To UBound(Vary)
For j = i + 1 To UBound(Vary)
If Vary(i, 1) = Vary(j, 1) Then
'I should delete the vary(j,1) element from vary
'in excel sheet we use selection.entirerow.delete
End If
Next j
Next i
End Sub
This is the sample I tried
A B C D
1 somevalues in BCD columns
2
3
1
Now Delete the 4th row don think I'm working for unique records I'm just learning stuff to do and while I was learning variant I am stuck at this point deleting a complete row stored in variant
I have stored (A1:D11).value in variant
Now how can I delete the A6 element or row in variant so that I can avoid it while I copy the variant to some other sheet?
Can I also delete the C AND B columns in variant so that when i do transpose it wont copy the C and B columns?
I don't know what exactly a variant is - I was thinking to take a set of range and do operations like what we do for an excel sheet then take that variant and transpose it back to sheet.
Is that the right way of thinking or did I misunderstand the use of variants?
`variant(k,1)=text(x)` some array shows mismatch ? whats wrong?
If you are planning on using a varray to look at cells in each row to decide if you should delete the row or not, you should loop through your varray backwards, the same way you would if you did a for loop through the cell range. Since you are starting on row 1, the variable i will always equal the row number the element was located on, so you can use that to delete the proper row.
Here's a sample (more simple than what you are trying to do, though) that will delete each row in which the cells in columns A and B are the same.
Sub test()
Dim varray As Variant
varray = Range("A1:B11").Value
For i = UBound(varray, 1) To 1 Step -1
If varray(i, 1) = varray(i, 2) Then
Cells(i, 1).EntireRow.Delete
End If
Next
End Sub
Notes of interest:
UBound(varray, 1) gives the count of the rows
UBound(varray, 2) gives the count of the columns
One workaround without a second array is to introduce a deliberate error into an element you want to replace, then use SpecialCells to delete the cell after dumping the variant array back over the range. This sample introduces an error into the array position corresponding to A6 (outside the loop as its an example), then when the range is dumped to E1, the SpecialCell error removal shifts F6:H6 into E6:G6. ie
pls save before testing - this code will overwrite E6:H11 in the first worksheet
Sub main()
Dim Vary As Variant
Dim rng1 As Range
Set rng1 = Sheets(1).Range("A1:D11")
Set rng2 = rng1.Offset(0, 4)
Vary = rng1.Value2
For i = 1 To UBound(Vary)
For j = i + 1 To UBound(Vary)
'your test here
Next j
Next i
Vary(6, 1) = "=(1 / 0)"
With rng2
.Value2 = Vary
On Error Resume Next
.SpecialCells(xlFormulas, xlErrors).Delete xlToLeft
End With
End Sub
