I've read the post on this VBA problem, but my VBA script is still not working.
Public Sub Test()
Dim arrNames As Variant 'Declare array named "arrNames"
arrNames = Sheet1.Range("F2:F1000") 'Array filled with column F
intN = Application.CountIf(arrNames, "*") 'does not work intent: count cells w/info
'intN = Application.CountA(arrNames) 'works but MsgBox displays value of 999
MsgBox (intN)
End Sub
How do I get the number of cells in my array containing any value?
EDITED version after help
Public Sub Test()
Dim arrNames As Variant 'Declare array named "arrNames"
Dim i As Long
arrNames = Sheet1.Range("F2:F1000") 'Array filled with column F
For i = LBound(arrNames) To UBound(arrNames)
If (arrNames(i,1) = "") Then
EmptyCounter = EmptyCounter + 1
End If
Next i
End Sub
There is no direct way to do it, as far as I understand. But you could run a simple loop to check if the values are equal to "" assuming string data.
For e.g.
For i = LBound(ArrayName) to UBound(ArrayName)
If (ArrayName(i) = "") Then
EmptyCounter = EmptyCounter + 1
End If
Next i
If it's numeric or other type of data, you may try variations of the above loop using functions such as IsEmpty(VariableName) etc.
You can try this:
intN = Worksheets("Sheet1").Range("F2:F1000").Cells.SpecialCells(xlCellTypeConstants).Count
MsgBox intN
100% it works.

I have been struggling with this for quite some time, but the error dialogue box that pops up isn't exactly the most helpful. I'm trying to extract a list of names from the worksheet and assigning them to an array using the range function. I tried and tried, but I couldn't seem to get it to work, so I tried reading in the cells 1 by 1 instead, using the Do Until Loop. I didn't expect to be posting this here, so the code of what I was doing before, is already gone, but here's an example:
Dim RangeList As Variant
RangeList = ThisWorkbook.Worksheets("Plan").Range("H1:H132").Value2
I switched it to the next method in hopes that it would lead to a more straightforward approach:
ReDim ResourceList(ResourceLength - 1)
I = 1
Do Until ThisWorkbook.Worksheets("Plan").Cells(I, 8).Value = ""
ResourceList(I) = ThisWorkbook.Worksheets("Plan").Cells(I, 8).Value
Workbooks("NEW PROJECT PLAN").Worksheets("Console").Cells(I, 2).Value = Resource
I = I + 1
Loop
The first one returns an empty range that 'Can't find any cells' and the second one gave me an array of empty strings 169 items long. I feel like I'm pounding my head against a brick wall on this one, any help would be appreciated.
Here is the entirety of the code that I'm trying to troubleshoot:
'Collects the List of Resources
Dim ResourceLength As Long, I As Integer
Dim ResourceList() As String
ResourceLength = ThisWorkbook.FinalRow(8, "Plan")
MsgBox ("Final Row is: " & ResourceLength) 'The Last row used in column 8
ReDim ResourceList(ResourceLength - 1)
I = 1
Do Until ThisWorkbook.Worksheets("Plan").Cells(I, 8).Value = ""
ResourceList(I - 1) = ThisWorkbook.Worksheets("Plan").Cells(I, 8).Value
Workbooks("NEW PROJECT PLAN").Worksheets("Console").Cells(I, 2).Value = Resource
I = I + 1
Loop
ResourceList = ThisWorkbook.FilterArray(ResourceList)
Dim myCount As Integer
Dim Source As Variant
For Each Source In ResourceList
Worksheets("Console").Cells(myCount, 1).Value = Source
myCount = myCount + 1
Next Source
Here is the FilterArray Function:
Public Function FilterArray(UnsortedArray As Variant) As Variant
Dim Intermediate() As Variant
Dim UItem As Variant
' Runs through each item and compares it to the list of items found, if it finds repeats, it throws them out.
For Each UItem In UnsortedArray
If Not ArrayItemExist(Intermediate, UItem) Then
' The Item does not Exist
ReDim Intermediate(UBound(Intermediate) + 1)
Intermediate(UBound(Intermediate)) = UItem
End If
Next UItem
' Returns the Sorted Array.
FilterArray = Intermediate
End Function
Private Function ArrayItemExist(TargetArray() As Variant, TargetItem As Variant) As Boolean
'Searches an Array for TargetItem and returns a boolean stating whether it exists within the Array or not.
Dim ItemFound As Boolean
Dim SItem As Variant
ItemFound = False
For Each SItem In TargetArray
If TargetItem = SItem Then
ItemFound = True
Exit For
End If
Next SItem
ArrayItemExist = ItemFound
End Function
Public Function FinalRow(Column As Integer, Sheet As String) As Long
' Finds the last Row used in the spreadsheet.
FinalRow = Worksheets(Sheet).Cells(Rows.Count, Column).End(xlUp).Row
End Function
When I try to run the software, I receive an error that the For Loop is not initialized, which I traced back to the 'ResourceList' Array/Range being empty.
[Edit]
This function is used to prep an array of names that are extracted from a list of dropdown box resources. This list may contain multiple instances of the same name, so it's sent to the FilterArray function to sort the array into an array with just one instance of each name. Example:
Before and after sorting
After this, it's sent to a module that will inject each name into a dictionary with a corresponding amount of hours that the person is scheduled to work.
I'm very new to VBA, to bear with me here.
I want to assign a set of variables the value of a set of ranges ie. run a brief code to simplify the following
Dim Sample 1 as string
Sample1 = activeworksheet.range("C17").value
Dim Sample 2 as string
Sample2 = activeworksheet.range("C18").value}
and so on
Following an excelfunctions.net tutorial, I know that I can shorten the declaration to
Dim Sample(1 to 20) as a string
But the tutorial drops it there(because it's a tutorial about names), suggesting I populate it as follows
sample(1)=activesheet.range("C7").value
sample(2)=activesheet.range("C7").value
and so on
I found the discussion below to be on the right track to answer my quest, but I am having trouble applying it to my situation. (Excel VBA Array Ranges for a loop)
As a follow up note, I am ultimately trying to assign values to these variables for use in the following procedures, rather than declaring and assigning them each time.
Thanks!
Try something like this:
Sub test()
Dim sampleArr(1 To 20) As String
Dim i As Integer
Dim rng As Range, cel As Range
i = 1
Set rng = Range("C1:C20")
For Each cel In rng
sampleArr(i) = cel.Value
i = i + 1
Next cel
For i = LBound(sampleArr) To UBound(sampleArr)
Debug.Print sampleArr(i)
Next i
Also, if you know the range you want to put into an array, you can simply set an array to that range:
Sub test()
Dim sampleArr() As Variant
Dim i As Integer
Dim rng As Range, cel As Range
i = 1
Set rng = Range("C1:C20") ' Note, this creates a 2 Dimensional array
sampleArr = rng ' Right here, this sets the values in the range to this array.
For i = LBound(sampleArr) To UBound(sampleArr)
Debug.Print sampleArr(i, 1) ' you need the ",1" since this is 2D.
Next i
End Sub
You should :
Define the range you want to retrieve data
For each cell of the range, retrieve your datas
dim tab() As string, cell as range, i as integer
i = 0
redim tab(0)
for each cell in ActiveWorksheet.Range("C1:C20")
tab(i) = cell
i = i + 1
redim preserve tab(i)
next
edit : I indent the code to display it correctly
Additional way to the above you can only use:
Arr = ActiveWorksheet.Range("C1:C20").Value
Then you can directly use:
Arr(i,1) where i is C1 to C20 range!
I have a sub which reads an Excel file (X rows by 5 columns) and make a copy of its data into a String array called 'matrix' in VB.NET. I do need, however, to access of this array in some other subs as well. I was hoping to pass the array to a class level array variable and then retrieve info from that one instead. But I don't how to achieve this goal.
Public Sub ReadFromExcel()
Dim excel As Application = New Application
Try
Dim wrkbook As Workbook = excel.Workbooks.Open(IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly.Location) & _
"EXCELFILE.xls")
Dim sheet As Worksheet = wrkbook.Sheets(1)
Dim cell As Range = sheet.UsedRange
Dim LastRow As Long = 0
sheet.Activate()
With sheet
LastRow = .Cells(.Rows.Count, 1).End(XlDirection.xlUp).Row
End With
Dim matrix(LastRow - 1, 4) As String
For i As Integer = 2 To LastRow
For j As Integer = 1 To 5
matrix(i - 1, j - 1) = cell(i, j).VALUE
Next
Next (i)
wrkbook.Close()
excel.Quit()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub
You might try this:
Public Class Sample
Private xlsFileContents(0,0) as String
Public Sub ReadFromExel()
Dim excel As Application = New Application
Try
'all of your code here up to "excel.quit"
'now redim the class array to match your matrix array
'<array>.GetUpperBound gets the integer value of the highest index in that dimension of your array.
'It accepts a zero-bound integer to determine which dimension you are referring to.
ReDim xlsFileContents(matrix.GetUpperBound(0), matrix.GetUpperBound(1))
xlsFileContents = matrix
Catch
'your code here
End Try
End Class
I tried this in a simple console application where I manually entered data into the matrix array, and it worked for me.
I would like to count the number of matching items in an array. I tried using
Application.Countif
MyCount = Application.WorksheetFunction.CountIf(Myrange, val)
but this returns an array full of errors rather than a simple count. I have also tried using Application.WorksheetFunction.Countif but this causes a 424 error.
I currently am testing on a worksheet with a short list of names in cells A1:A20, but ultimately I plan to use this code with a very large CSV file and I want to load the information into an array before using CountIf (rather than using the range).
Sub TestCount()
Dim MyCount
Dim Myrange As Variant
Dim val As String
val = "Addison"
Myrange = ActiveSheet.Range("A1").CurrentRegion.Value
MyCount = Application.WorksheetFunction.CountIf(Myrange, val)
MsgBox (MyCount)
End Sub
Can anyone suggest what I did wrong?
You have several problems.
Using CountIf
First, if I understand right, you are intentially trying to use the Application.WorksheetFunction.CountIf statement on an array. That will only cause trouble, since CountIf (as the statment suggests) is a "worksheet function" not a "VBA Array function".
Ditto has created a solution that uses CountIf correctly, by setting a range in the worksheet on which the CountIf statement performs its job. If all you want is a way to count the value within that range, that is the way to go.
Creating an array from a range
Second, if you really need to get the items out of the worksheet and into an array (for example, if you plan to work with those values in ways you don't want to effect the worksheet), you should know that you have only partially solved the question of creating an array of values from a range selection.
You are correct that to establish an array by assigning a range to a variable you need a variant, but you have forgotten the parenthesis, which are an essential part of denoting an array.So, instead of Dim Myrange As Variant you should use Dim Myrange () As Variant
Having established MyRange as an array, you can now assign the array values by saying MyRange = Range("x") where x is the area being captured. You do not need to (or want to) use .Value for this. VBA will automatically do that for you. So, in your case you want to use the CurrentRegion for Range("A1") which is done like this: MyRange = Range("A1").CurrentRegion. You could also use a closely defined range like this: MyRange = Range("A1:A12") or MyRange = Range("C7:F14"). Note: I left off the ActiveSheet because it does not work when assigning ranges to arrays. The assumption is that you are using the active sheet, and the current region is for the cell indicated in the Range("x") statement.
Counting values within the array
Third, once you have succeeded in creating an array, you won't be able to use Countif (as noted above). You'll need to create a method of counting that value within the array. There are several considerations in doing this.
Since an array created from a range will be two dimensional and may have more than one column, you should not assume just one column. You will want to create a variable that holds the number of rows and number of columns, so you can loop through the entire array. Something like this:
Dim Row As Long
Dim Col As Long
You will want to define the limits of your loops using the UBound of the array dimensions. Something like this:
Dim RowNumber As Integer
RowNumber = UBound(MyRange, 1)
Dim ColNumber As Integer
ColNumber = UBound(MyRange, 2)
Code for using an array to find your count
I think the following code will do what you want using an array created in the manner you were attempting:
Sub TestCount()
Dim MyCount As Long
MyCount = 0
Dim MyRange() As Variant
MyRange = Range("A1").CurrentRegion
Dim val As String
val = "Addison"
Dim Row As Long
Dim Col As Long
Dim RowNumber As Long
RowNumber = UBound(MyRange, 1)
Dim ColNumber As Long
ColNumber = UBound(MyRange, 2)
For Col = 1 To ColNumber
For Row = 1 To RowNumber
If MyRange(Row, Col) = val Then MyCount = MyCount + 1
Next Row
Next Col
msgbox MyCount
End Sub
Just because this horse hasn't been beat enough already..here is a 1 liner
Sub Button3_Click()
MsgBox Application.WorksheetFunction.CountIf(Range("A1:a20"), "Addison")
End Sub
Try this:
Sub TestCount()
Dim MyCount
Dim Myrange As Range
Dim val As String
val = "Addison"
Set Myrange = ActiveSheet.Range("A1:a20")
MyCount = Application.WorksheetFunction.CountIf(Myrange, val)
MsgBox (MyCount)
End Sub
1) define "Myrange" as a RANGE, not a variant.
2) use "set" keyword to assign range to Myrange
3) give it the range you want: "a1:a20", not just "a1"
Yes, you didn't declare you range as a range type, so you didn't set the range.
Sub Macro1()
Dim val as String
Dim r As Range
Set r = Range("a1:a20")
val = "Addison"
MsgBox Application.WorksheetFunction.CountIf(r, val)
End Sub
or
Sub CritSrh_Column()
Dim cell As Variant
Dim counter As Integer
For Each cell In Range("A1:A20")
'could use ("A:A") to search the whole column #not recommended#
'for dynamic rows, use end.xl('direction')
If cell.Value = "Addison" Then
counter = counter + 1
End If
Next
MsgBox counter
End Sub
I'm pretty new to visual basic, but I'm having trouble assigning cell values to members of an array. Basically what I am doing is looping through a column and assigning each cell to a new part of the array. Test code is posted below:
Sub Test()
Dim List(5) As String
Dim celltext As String
For i = 1 To 5
celltxt = ActiveSheet.Range("K" & i).Text
List(i) = celltext
MsgBox List(i)
Next i
End Sub
Each time the message box pops up though, it is blank, meaning that the assignment didn't work. The cells at those coordinates DO have values. Any clues?
You are assigning to "celltxt" but reading from "celltext".
Add Option Explicit at the top of every module -- that will make these types of errors more obvious.
When you Dim List(5) As String. The lowest element in the array is 0 and not 1. You might want to change that to Dim List(1 to 5) As String else your first element will always be blank in the array.
You are using ActiveSheet. Are you sure it is the right sheet?
Try this code
Sub Test()
Dim List(1 To 5) As String
Dim ws As Worksheet
Dim i as Long
Set ws = ThisWorkbook.Sheets("Sheet1")
For i = 1 To 5
List(i) = ws.Range("K" & i).Value
MsgBox List(i)
Next i
End Sub
You might also with to try:
Dim List As Variant
Dim i As Long
List = ActiveSheet.Range("K1:K5")
For i = 1 To UBound(List)
MsgBox List(i, 1)
Next i
This will add performance by only reading from the worksheet once instead of each time the loop is looped.
