Pass A Built Array Back To Formula

Nov 11, 2009

Iím trying to send an array of values INTO a user defined function, do a little math on it, and then send the resulting array back to the caller. The caller in this case is an array formula in an excel cell.

I can get it to build an array after the math, but I canít get it to pass the resulting array back to the formula. The following snippet is a simple version of the code. Here I am building the incoming array in the macro, but same difference at the end. The outgoing Oil_spgr variable never seems to contain the full, final array.

Pass Values From An Array To A Range

Nov 21, 2008

You have an array and a range of the same size and you have to put the array values into the range, something like this:

Dim i As Integer
Dim myCell As Range
Dim myArray(10) As Double

i=0

For Each myCell In Range("A")

myCell.Value = myArray(i)
i = i + 1

Next myCell

except that this code looks a bit awkward to me.

Pass Array Variables Between Modules

Jun 8, 2007

I am trying to pass a public variable to another module in the same workbook. On Module1 I declare at the top

Public stores
Sub Main()
Dim stores(1 To 100, 1 To 10, 1 To 10)

Reader

...which then calls the procedure Reader in Module2

Sub Reader()
let x=1
let y=1
let z=1
let stores (x,y,z)=activecell.value

I've left out the portions of code that seem irrelevant. When the macro runs, I get a type mismatch error on the "let stores" line. If I move the code from Reader into the procedure Main, it works, so it seems to be an issue with passing the variable. I haven't used multiple modules very often so this is probably a very basic issue.

Pass Variable Into Array As Element

Oct 2, 2007

I am trying to pass information that is filled by user in a userform into an excel sheet. Let's say a user would click on a control button in a userform and Macro would ask him what value to store for the first variable. If user clicks one more time then Macro would identify that it was a second click and ask what value to set for a second variable. It is easy to do with limited number of variables, but is it possible that the variable which stores a number of clicks would become a number for variable to store the value?

1 click - a1 = ..
2 click - a2 = ..
....
n click - an = ..

If not possible - which way to search a solution?

Pass Array Elements To Private UserForm Module

Mar 28, 2008

I am trying to pass a string array into a form. I have added a member string array to the form, and a property to "Let" the array in the the member array.

Private sFormString() As String

Property Let FormString(value() As String)
sFormString = value
End Property

I can pass a string in using a procedure:

Sub StringArrayTest1()

Dim TestString() As String
Dim frmString As FString

but I cannot "modulate" the code, or else I get an internal error (error 51). I.e. this code doesn't work:


Sub StringArrayTest2Mod(TestString() As String, frmString As FString)

frmString.FormString = TestString

End Sub

Sub StringArrayTest2()

Dim TestString() As String
Dim frmString As FString

Set frmString = New FString
Redim TestString(1 To 2)
TestString(1) = "Cat"
TestString(2) = "Dog"

Call StringArrayTest2Mod(TestString, frmString)

End Sub

Does anyone know why this happens? Obviously, in the example code its not an issue, but the application I'm using this for is more complex, and some modulation here would be good.

Excel 2010 :: Transferring Array Back To Worksheet?

Jun 20, 2014

I have a workbook that is doing something I don't understand. In several places I am using arrays to transfer/modify information, then placing the array back onto the worksheet, and this works perfectly. The following code... doesn't.

(I've cut out unnecessary code like variable declarations - all my integer items are declared as Long)

Code:
Dim varA As Variant, varB(10000, 1) As Variant
Set wkDest = Sheets("a")
erB = 0
For lpTerm = 1 To 4

[Code]...

and several other ways. What happens is just null output, a full column of nothing. However, when I expand my worksheet range to two columns, all the data from varB appears - it is shifted down one column and row. So my data starts at .cells(2,2) instead of .cells(1,1). The data is all perfect, I've verified it left and right.... I just can't figure out why it's getting shifted like this.

Pass Formula Result To Variable

Jul 26, 2007

I have come up with the following formula to pull sums of data by month. I am using this because it is inconvenient to use the DSUM formula (I can't put all the criteria together in a simple way):

{=SUM(IF('Sheet1'!$B$2:$B$20="Person1",IF( DATE(YEAR('Sheet1'!$A$2:$A$20),MONTH('Sheet1'!$A$2:$A$20)+1,)=C2,'Sheet1'!$D$2:$D$20,0),0))}

I would like to, in a macro, assign a variable to this result - but cannot figure out the VBA code for it.

Calculating Distances Between Back-to-back Locations

Aug 11, 2012

I have a layout something like the following:

A1
A2
A3

[Code]....

Where each (i.e., A1) represents a location. I have tried to use a coordinate system but this will not work for the back-to-back locations. (Assuming each location is 2 feet wide, For example A1 to C1 is 4 feet apart, not 2 feet (as Euclidean or rectilinear would calculate it as).

Would there be a way to incorporate an if statement for those locations that are back-to-back? As a rectilinear distance calculation would work as long as the locations are not part of the same "block".

Ultimately I am looking to have a matrix which contains all the distances between each location:

A1
A2
A3
B1

Change Sheet Name In Cell And Pass Through Formula

Mar 23, 2007

I can't use code for this problem as I need to give this to someone who doesn't know VBA. They will need to use it in several different reports, so I can't produce something in VBA very easily. I have three worksheets, Summary, Year1 and Year2.

I want to display either Year1 or Year2 data in the Summary sheet depending on what the user enters in a cell in the Summary sheet. For example, if the user enters "Year1" in cell E2 then I want to point to a cell in the Year1 spreadsheet.
I tried using formula: =E2 & "!B3" but this doesn't work. Is there another solution? I have attached an example.

Formula Keeps Bringing Back Offset?

May 30, 2014

Here is my formula:

=IFERROR(INDEX(Stored!$D$22:$AN$795, MATCH(D11,Stored!$E$22:$E$795,0), MATCH(E10,Stored!$C$22:$AN$22,0)),0)

For some reason it keeps pulling back the value that is one cell to the right, so one column off.

What could it be.

In this example it should pull back N363 and it is pulling back O363.

Formula For Counting Back A Year?

Jan 17, 2012

know if there is a formula for counting back a year from a date?

Basically what I have is we operate a rolling absence/ sick year and so what happens is on a staff members return from absence/ sick we look back exactly one calendar year from the last day of absence and count the number of days off absent in that period for comparison against their paid allowance.

I have posted a mock up sheet and what I am looking for is a formula for column C. The highlighted cells are the period it would be if today was the last day of absence.

Sheet1  ABC1Days AbsentDateRolling2201/01/2010 3302/02/2010 4403/03/2010 5207/06/2010

I want the code to say, If Qtr = 1 And Year = 2007, then bring back Org Name, If Qtr = 2 And Year = 2006, then bring back Org Name and so forth.

The code should loop through a range of constant data (Region Name), until the Region Name is blank.

Dim OrgCell As Range
Dim OrgTargetCell As Range
Dim RegionCell As Range
Set OrgCell = Sheets("DATA Removed").Range("A2")
Set OrgTargetCell = Sheets("Overdue").Range("A3")
Set RegionCell = Sheets("DATA Removed").Range("C2")
i = 0

OrgCell.FormulaR1C1 = _

cell AT7 is a formula which brings back a numerical value i.e. 15.

in cell AS7 i need a formula that displays the value of cell AT7, as long as that value is less than 15, if the value is 15 or higher then 0 should be displayed.

I dont know why i cant get this, seems like a simple IF statement to me, but who knows.

Once this formula is done i need to drag it down about 2500 cells and autosum to get a column total...

Converting 3x10 Array To A 1X30 Array To Run A Match Formula

Apr 7, 2009

Say I have 3 columns of data: A1:C10 and I want to run a Match() function on them all together to see if I get a match any one those cells, say the value of have in X1.

Since, Match only allows a One-Column lookup array.. is there a way to "concatenate" or "append" the 3 columns together within a formula so now I would be looking to Match in an array that is 1 column * 30 rows?

Basically want to convert =Match(X1,A1:C10,0) to =Match(X1,A1:A30,0) without moving around the raw data in the sheet.

And I want to avoid doing an AND or OR formula that uses 3 separate MATCH() for each column.

I have a hunch that the MMULT or MMULT/TRANSPOSE functions are involved, but can't seem to get it right.

Formula To Count 12 Months Back For Finance Calculation

Mar 24, 2009

I have a spreadsheet that each month, we populate a new row of data. The rows are already set up in the spreadsheet, but we just populate the new row.

We are calculating a rolling 12 month total. Each month, we have to modify the formula below to pick up the last 12 months.

For example, next month we will populate data into cell M91, then we need to manually modify our formula to read M80:M91. Wondering if there is a way to have the formula below to look at a range, such as M100:M1, and count the last 12 months? This would eliminate us having to change this each month on several spreadsheets.

In Summary: I would like to replace the M79:M90 to count the last 12 months instead of changing the formula each month.

Here is the formula:
=(FVSCHEDULE(1,M79:M90/100)-1)*100
