I am trying to create an array of a user set length that users can add values to that will be saved and output on multiple sheets. I am very new to VBA so I do not know if what I am trying to do is possible but I have tried a few methods unsuccessfully.
This is the code I have so far
Sub addCost()
Dim costArray() As Variant
ReDim Preserve costArray(1 To Range("b2").Value)
For i = 1 To Range("b2").Value
costArray(i) = 0
Next i
Dim newCost As Variant
Dim costYear As Variant
newCost = InputBox("New cost amount:")
costYear = InputBox("Year new cost is active:")
costArray(costYear) = newCost
End Sub
Here is what the input tab looks like in excel
With the length of the array being the project lifespan and the add new cost activating the code, clear costs are still in progress. Is there a way for the array to store after multiple executions of the addCost sub?
Thanks!
This link Microsoft shows some methods of store values after the macro ending (in your case, sub addCost)
I think the first solution will be good for you.
Other solutions is use Access to store data (specially if you need these data over time) or a new and clean worksheet where you can store array entries in a cell (This is a very practical solution if the number of entries does not get too big)
I have a sheet that the values of a range change each time I change a specific cell. Let's say that the cell C8 is an indentity of a person and column H the scheduled monthly repayments. I need to find the aggregate monthly repayments, hence on each possible value of C8 (and that actually means for every person as you can think of different values of C8) I need the aggegate of repayments, hence the aggegate of cell Hi Hence, keeping row i constant and changing cell C8, I always need to sum Hi. So I actually need sum(Hi) (i constant and the index of the sum is cell c8, so if c8 takes value from 1 to 200, I need the sum(Hi(c8)), again row i . Hi(c8) it is just a notation to show you that Hi depends on the value of c8. The actual formula in cell H10 is INDEX('Sheet2'!R:R,MATCH('Sheet1'!$C$8,'Sheet2'!F:F,0)))). H11 and onwards have the same formula with slight twists for the fact that the repayments are not always equal, but the index function remains the same.
Then, the total of H10 for all possible values of c8 is pasted in c17, the total of H11 is pasted in C18 etc. Please find some images below, maybe that helps to support what I try to achieve. enter image description here
I have the following code for that purpose. Note that the above example was just to explain you a bit the background, the cells and the range that changes are different.
sub sumloop()
Application.ScreenUpdating = False
Application.DisplayStatusBar = False
Sheets("Sheet1").Range("C8").Value = 1
Dim i, k As Integer
i = 1
k = Sheets("Sheet1").Range("C9").Value
Dim LR As Long
LR = Sheets("Sheet1").Range("C" &
Sheets("Sheet1").Rows.Count).End(xlUp).row
Sheets("Sheet1").Range("C17:C" & LR).ClearContents
Do While i <= k
If (Sheets("Sheet1").Range("J9").Value = "") Then
Sheets("Sheet1").Range("h10:h200").Copy
Sheets("Sheet1").Range("c17").PasteSpecial
Paste:=xlValues, Operation:=xlAdd, SkipBlanks:= _
False, Transpose:=False
Else
Sheets("Sheet1").Range("h9:h200").Copy
Sheets("Sheet1").Range("c17").PasteSpecial
Paste:=xlValues, Operation:=xlAdd, SkipBlanks:= _
False, Transpose:=False
End If
Sheets("Sheet1").Range("C8").Value = Sheets("Sheet1").Range("C8").Value+1
i = i + 1
Loop
Sheets("Sheet1").Range("C8").Value = 1
Application.ScreenUpdating = True
Application.DisplayStatusBar = True
End Sub
The if inside of the loop is needed as the location of the first value of the range depends on some criteria which have not to do with the code. Also k denotes the maximum number of possible values. What I need is approximately 250.
While the code works, it takes approximately 40 seconds to run for 84 values of cell C8 and approximately 1.5 minute for 250. I tried some things, changed do while to for but nothing significant, used variable ranges instead of fixed ones like h10:h100, very similar to what I do with Sheet1.Range(C17:C&LR). Again no significant changes. As I am very new to vba I don't know if 1.5 minutes are a lot for such a simple code, but to me it seems a lot and this analysis is needed for 10 different combinations of 250 different values for cell c8, which means 15 minutes approximately.
I would appreciate if anyone can suggest me something faster.
Thank you very much in advance.
Here is a complete solution, with explainations in comments.
Because we do not have you source spreadsheet, I could not run any tests on this.

OK, A few things.
Firstly, Dim i, k As Integer doesn't do what you think it does, you need to do: Dim i As Integer, k As Integer
Secondly don't use Integer in VBA use Long so Dim i As Long, k As Long
Third the calculations are killing you. Turn them off with Application.Calculation = xlCalculationManual at the start of your code and back on with Application.Calculation = xlCalculationAutomatic at the end of your code.
Now we are presented with really fast code but the problem that it doesn't update on each iteration which you need it to do. You can calculate just a range like so: Sheets("Sheet1").Range("h10:h200").Calculate so put that in just before you copy the range
There will be an even faster way to do this but I just can't seem to wrap my head around your requirements so I am unable to assist further.
Welcome to StackOverflow.
I must admit I got a bit confused by your narrative, as I did not fully understand if you are doing a sum(a,b,c) or a sum(sum(a,b,c), sum(d,e,f), ...).
In any cases, a trick that will dramatically accelerate your script is the use of arrays.
Performing calcs with VBA is not slow, but retrieving the data from Excel (communicating with the application) IS slow, and pretty much depending on the number of "requests", rather than the quantity of data requested.
You can use arrays to request the data from a range all at once, isntead of requesting the value of each cell separately.
Dim Arr() As Variant
Arr = Range("A1:E999")
It is as simple as this.
Give it a try and if you are still struggling let us know.
BONUS
If you are new to Arrays, keep in mind you can have a two-dimmensionnal array:
Dim 2DArray(0 to 10, 0 to 50)
Or a stacked array (an array of arrays):
Dim MyArray() as String
Dim StackedArray() as MyArray
Dim StackedArray() as Variant
You will need a 2D-Array for extracting the data from a range, but I feel you may need an Array of 2D-Arrays for your Sum of Sums.

How to achieve the same through pivot charts (no VBA)
Step 1
First, you must organize your data in a specific way, where each column is a field, and each row is a data entry. If you are not familiar with databases, this is the most tricky point as you may arrange your data in different ways.
Long story short, we will take an example where you have 3 customers and 4 dates.
So that is 12 data entries, which will provide the repayment value for each of the possible customer ID and date.
Step 2
Select that data and insert a PivotChart.
Note: you could insert a PivotTable alone, or a PivotChart alone. I recommend the option hwere you insert both, as managing your data will be more intuitive when working on the Chart. The table is updated at the same time you update the chart.
Step 3
Make sure the all your data is selected, including the top row which will dictate the name of each field (the name of each column).
Step 4
A new sheet has just been create, and you can see where both your PivotTble and PivotCharts will appear. Select the chart.
Step 5
A menu to the right will appear (it might have already been there, so make sure you selected the Chart and not the Table, as that menu would be slightly different).
Step 6
Drag and drop the field names into the categories as shown.
What you are doing here is telling Excel what data you want to see (Values) and how you want to break it down (per date, and per customer).
Step 7
By default dates data is always groupped quartile and year. To be able to see all the date we have data for, you can click the [+] near the data on the Table: this will show more details for both the table and the chart.
Step 8
But we want to get completely rid of the quartils and years. In order to achieve this, you need to right click any value of your date column in the Table, and choose "Ungroup" as displayed.
Step 9
Your data now looks like this.
Note the time axis is not on scale. For example if you hae monthly data and a month is missing, there will be no gap. This is one of the difficulties with Pivot data. This can be overcomes, but it is off topic here.
Step 10
Now we want to have a cumulative view of the data, so we want to play with the way the values are proessed by Excel.
Select the chart, then in the right panel: right click on the "Sum of Repayment" field, and select "Value Field Settings".
Step 11
In the "Show Values As" tab, select "Show values as" "Running Tital In".
Then choose "Date".
Here we are telling Excel that the value to display should be a cumulative total, cumulated according to the "Date" field.
Press OK.
Step 12
You now have what you are looking for. If you look in the Table, you have one column per Customer ID, and one row per date. For a given Date, you have the cumulative repayment made by a given Customer ID. At the very right, you have the Grand Total, which is, for a given date, the sum of all the Customer ID values.
Step 13
The Chart keeps showing the cumulative payment per CUstomer ID, and we cannot see the grand total.
In orer to achieve this, simply remove the "Customer ID" field from the "Legend (Series)" category area in the Fields Panel, as shown. (you can untick the Customer Id [x] box, or you can drag and drop it from the category area to the main list area).
Step 14
Now we only have the Grand total in the chart. But why?
If you display the "Value Field Settings" of Sum of Repyament" (Step 10), the first tab "Summarize Values By" will tell Excel what to do when several value meet the same Legend and Axis values.
Now that we removed the Customer ID field from the Legend area, for each date, we have 3 repayment values (one for each Customer ID). In the field settings, we tell Excel to use a "Sum". So it returns the sum of the 3 values.
But you could play around and return the Average, or even use "Count", which will show you how many records you have (it will return 3).
That is why pivot charts are so powerful: with only a few clicks and/or drag and drop, you can display a myriad of different graphics for your data.
For future interest, you should look online for Filters, and "Insert Slicer" (which is equivalent to filtering, but will add button directly on your chart: great when showing the data to colleagues and switch from one setting to another)
Hope this helped!
I have a script (thanks to SO for the help with that one!) to allow a user to select a number of discontinuous columns and insert their indexes into an array. What I need to be able to do now is efficiently select the remaining columns i.e. the ones that the user didn't select into another array to perform a separate action on these columns.
For example, the user selects columns A,C,F,G and these indexes are put into the array Usr_col(). The remaining columns (B,D,E) need to be stored in the array rem_col()
All I can think of right now is to test every used column's index against the array of user-selected columns and, if it is not contained in that array, insert it into a new array. Something like this:
For i = 1 to ws.cells(1, columns.count).end(xltoright).column
if isinarray(i, Usr_col()) = false Then
rem_col(n) = i
n = n+1
end if
next
I am just looking for a more efficient solution to this.
I agree with #ScottHoltzman that this site wouldn't normally be the arena to make working code more efficient. However, this question puts a different slant on your previous one, as the most obvious solution would be to assign column numbers to one or other of your arrays in one loop.
The code below gives you a skeleton example. You'd need to check the user's selection for proper columns. Also, it isn't great form to redimension an array within the loop, but if the user selects adjacent columns then you'd need to acquire area count and column count to get the array size. I'll leave that to you if rediming within the loop jars with you:
Dim targetCols As Range, allCols As Range
Dim selColNum() As Long, unselColNum() As Long
Dim selIndex As Long, unselIndex As Long
Set targetCols = Application.InputBox("Select your columns", Type:=8)
For Each allCols In Sheet1.UsedRange.Columns
If Intersect(allCols, targetCols) Is Nothing Then
ReDim Preserve unselColNum(unselIndex)
unselColNum(unselIndex) = allCols.Column
unselIndex = unselIndex + 1
Else
ReDim Preserve selColNum(selIndex)
selColNum(selIndex) = allCols.Column
selIndex = selIndex + 1
End If
Next
I have List A and B in excel and would like to compare ALL the items in List A with ALL the records in List B and if they match or partial match return the value of B in 3rd column. Hopefully demonstrated in the attached.
example
The easiest way to achieve it is to use VBA. Please find below example function which you can use in the same way as Excel functions:
Public Function findArea(item As String, areaRng As Range) As String
Dim i As Long
Dim ARR_area() As Variant
ARR_area = areaRng.Value2
For i = LBound(ARR_area) To UBound(ARR_area)
If (item Like "*" & ARR_area(i, 1) & "*") Then
findArea = ARR_area(i, 1)
GoTo endFunc
End If
Next i
endFunc:
End Function
Where:
item - Item which you want to check vs. areas
area - range of areas you want to check.
See usage example:
To achieve this result without you would need to format table to pivot view, where in rows you would have item and in rows area - as the value you can check matching for each combination. Nevertheless in this particular example I would recommend to use VBA.
Hope it helped.
VBA is not my particular strength, but here we go:
I would like to trigger a macro once a group of columns is hidden or shown. How can I archive this?
The results of my previous research
The only good hint about this I could find is this discussion at MSDN. Here, a solution is using the following way is drafted:
From the root dir of the xlsx file create a file customUI\customUI.xml with the content
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" >
<commands >
<command
idMso="ColumnsHide"
onAction="ColumnHide_onAction"/>
<command
idMso="ColumnsUnhide"
onAction="ColumnUnhide_onAction"/>
</commands >
</customUI >
and add
<Relationship Id="edTAB" Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="customUI/customUI.xml" />
to the _rels\_rels.xml. (All this probably is much easier using Visual Studio, but I have no access to such sophisticated tools in the microsoft world...) Now, the macro can be used the following way:
Public Sub ColumnHide_onAction(control As IRibbonControl, ByRef cancelDefault)
'
' Code for onAction callback. Ribbon control command
'
MsgBox "Ribbon Column Hide"
cancelDefault = False
End Sub
Public Sub ColumnUnhide_onAction(control As IRibbonControl, ByRef cancelDefault)
'
' Code for onAction callback. Ribbon control command
'
MsgBox "Ribbon Column Unhide"
cancelDefault = False
End Sub
This approach perfectly catches hiding and unhiding of columns, but not hiding and unhiding of groups. So, close, but not quite there.
Downloading the possible idMso values from here, I got notice of the GroupViewShowHide control. Using this the same way as ColumnsHide or ColumnsUnhide does not archive the desired result, though.
Any ideas?
For hiding groups of columns, I've noticed you haven't used the .Hidden property in your code example. It can be quite useful, especially if you define a group of columns in an array. For example:
For byti = 0 To UBound(cols())
If Hide Then
ActiveSheet.columns(cols(byti)).EntireColumn.Hidden = True
...and so on.
To check if a group of columns is already hidden or not, you could also use an array. Group your columns by assigning them to an array, then compare your worksheet's current status (what columns are hidden, what are not) to that array.
The code below is a suggestion for starting, and you could adapt to your project. It doesn't require the customUI.xml file you mentioned in your question.
The key parts are the MyColumnCheck variant, which is used to check if columns are hidden, and the .Match method. This is the VBA equivalent of the Match spreadsheet function.
Working on this code taught me much about how to search within arrays, and the ups and downs of using Match versus other methods - such as Find and just looping through an array! This has been discussed in several posts already, see this one for a good example. I chose to do Match rather than a For...Next loop, although it would be easy to include a For..Next loop that checks if a hidden column is in a group you assign.
If you're wondering about the IfError statement:
Application.IfError(Application.Match(MyColumnCheck.Column, MyColumnArray, 0),...
... this is because using Match in VBA code is often somewhat tricky as mentioned here. Also, as #Lori_m wrote here, "Using Application without .WorksheetFunction returns a variant which allows for arrays in arguments and results."
Also, I chose to change the values of the group array to -1 as they were checked, so when the procedure was done a little simple math would reveal if all the columns referenced by the array were hidden. A negative number is better for this check because I'm assuming you would refer to an actual column with only positive numbers.
So, to sum up, .Match can be used effectively to check if the hidden columns on a worksheet match a group of columns defined by an array.
'the column group you're looking for, dim as a dynamic array of column numbers
Dim MyColumnArray(1) As Long
'MyColumnArray(0) is column 2 or "B", MyColumnArray(1) is column 3 or "C", etc
MyColumnArray(0) = 2
MyColumnArray(1) = 3
Dim MyColumnCheck As Variant 'column check
For Each MyColumnCheck In Worksheets("Sheet1").columns
'if the column is hidden and exists in MyColumnArray array...
If columns(MyColumnCheck.Column).EntireColumn.Hidden = True And _
Application.IfError(Application.Match(MyColumnCheck.Column, MyColumnArray, 0), 0) > 0 _
Then
MyColumnArray(Application.Match(MyColumnCheck.Column, MyColumnArray, 0) - 1) = -1
'... set that element of the MyColumnArray array to -1.
End If
Next
If WorksheetFunction.Sum(MyColumnArray) = 0 - (UBound(MyColumnArray) + 1) Then
Debug.Print "group MyColumnArray is hidden"
'execute code here for when the group is hidden
Else
Debug.Print "group MyColumnArray is visible"
'execute code here for when the group is visible
End If
