Passing Multidimensional Array To Function
Jul 15, 2014
I'm trying to pass a multidimensional array to a function that I have defined, but I receive an error about an object mismatch. Here is what I have in regards to the array and function. What should I change?
Code:
Dim diffArray() As Integer
Dim countArray() As Integer
Redim countArray(count,2)
diffArray = getRunningSum(countArray)
End Sub
Public Function getRunningSum(ByRef countArray() As Integer) As Integer()
'Code here......
End Function

I want to create a multidimensional array. Basically, I want to tie a file to a sheet. I want to import the following files:
"byemployee.csv",
"byposition.csv",
"Status report.xls",
"bydepartment.csv",
"byband.csv"
to the following sheets in my workbook:
"byEmployee",
"byPosition",
"statusReport",
"byDepartment",
"byBand"
Basically, I would like to pass the array by reference. Basically, the code below imports the file into my workbook, but I since I have several files going into sheets in the workbook, I don't want to write the code 5 times. I figured the best way would be to create a multidimensional array and pass through my procedure below.
Code:
Sub import_Employee_Data()
strSourceFile = ThisWorkbook.Name
strPath = ThisWorkbook.Path & ""
strFirstImportFile = strPath & "byemployee.csv"
sDestSheet = "byEmployee"
If Len(Dir(strFirstImportFile)) > 0 Then
[code]......

Im working on a project where a spreadsheet holds data which is spread over multiple rows. The number of rows can change depending on the case.
Imagine 1 case being 1 row of certain details, then a various number of rows below detailing some different information in different columns.

I'm getting a compile error "Can't Assign to array" when I try to return a multidimensional array from a function. I'm not a VB expert, and I was unable to find any examples of returning a multidimensional array from a function. Here is some sample
Sub someSub
Dim data(1 To 4, 0 To 23) As Integer
For counter = 1 To numSheets
data = processData(counter, data) ' The error happens here
Next
End Sub
Private Function processData(counter As Integer, data() As Integer) As Integer()
Dim dataCopy(1 To 4, 0 To 23) As Integer
dataCopy = data
'modify dataCopy
processData = dataCopy

I have 9 named ranges on worksheet Sheet1. I want to print every combination of every non-singular range on worksheet Sheet2. Below is a simplified version of the scenario.
There are three named ranges: Letters, Colors, Animals. Say the below are the entries for each range.
Letters = {A, B, C}
Colors = {Red, Blue}
Animals = {Dog}I want to print every combination of Letters and Colors but exclude Animals since it only has 1 entry.
Therefore my result would look something like this:
A Red
B Red
C Red
A Blue
B Blue
C Blue
My thought is to make a multidimensional array GrandArray where GrandArray(1) = Letters and GrandArray(2) = Colors, then recursively go back through every combination and print to Sheet 2. I can set up GrandArray, but stepping through each element is creating mismatch errors.
I'm trying to avoid For loops since my real data has 9 ranges which may or may not be included in the final print.

I have data in a dictionary object and need to load it into a two column listbox. The VBA help says you can load data into a multicolumn listbox from a 2D array. So my question is how can I extract the data from a dictionary object directly into a 2D array.
The dictionary object stores data in key and item pairs. So the 2D array would have one dimension for the keys and the other for the items. I want to do this without having to extract the items and keys into separate 1D arrays and then loop through them to build the 2D array.

I need to multiply matrix variable by a constant (each matrix entry has to be multiplied by the constant).
Sub Matrix()
Dim X As Variant, Y As Variant
Dim a As Integer
a = 2
X = [1, 1, 1; 2, 2, 2; 3, 3, 3]
Y = X * a ' Here it writes that type is mismached
End Sub
I read that in cell functions it is possible to do such calculations.

How to apply a filter over the array "a" shown below and get the result in a new array "b" containing the filtered values based on the following conditions (the conditions criteria could be 1, 2 or 3. In this case only 2):
Criteria1 in Column 4="yellow"
Criteria2 in Column 3="ggg"
And only show values of columns 1 and 3.
If were using an SQL query would be something like this:
Code:
SELECT F[1],F[3] FROM "Table" WHERE F[4]="yellow" and F[3]="ggg"
The output array would be as below:
Code:
b=[{12,"ggg";140,ggg}]
this is the array:
Code:
Sub test()
a = [{"122","53","ggg","yellow";"140","9","ggg","yellow";"16","-22","ddc","yellow";"127","-37","ddc","green";"53","-28","ggg","grey"}]
'Filter code to get array b
'

I want to pass an array to Offset in the "Height" parameter, without having to type the array.
{=MAX(SUBTOTAL(9,(OFFSET(A1,ROW(1:5),,{1,2,3,4,5}))))}
I can't seem to figure out how to build the {1,2,3,4,5}. I've tried another ROW(1:5) and have tried nesting that like N(ROW(1:5)) but nothing works.
How I can get the {1,2,3,4,5} without having to type it out (so that I can expand this to a larger list)??

I'm trying to pass an array from one userform to another. When I run the script, it says: "Constants, fixed-length strings, arrays, user-defined types, and Declare statements not allowed as Public members of an object module". It explains further that you cant make an array public. How can I pass my array between forms? It suggests using an varient that contains an array, I tried doing this, heres my
Dim multiAry(15) As Range
Public vmultiAry As Variant
'... and later:
vmultiAry = multiAry
'... and on the next userform:
Dim multiAry(15) As Range
multiAry = UserForm1.vmultiAry
With this, I get an error saying "Compiler error: Cant assign to array" with "multiAry =" selected. Am I doing it totally wrong? How can I pass an array between forms?

Okay, I made an epic fail on a previous post that i turned to Solved, a real error on my part of not fully testing before i posted Solved, basically i was so excited that i'd solved it myself, well partially.
I have the following code in the first sub routine that collects which option button has been selected.
[Code] .....
The second sub routine is per following.
[Code] .......
Unfortunately when i tested this with only one variable myRev(1) it worked fine but when i added more myRev variables 2 thru 4 if failed, so is there a trick to passing an array variable between sub routines?

What I am trying to do is to automatically build a "tree" diagram representing the links in a huge model which is dynamically configured. What I have a problem with is the following:
The tree consists of layers, I start off with the top layer and for each entry in the top layer I can add all its subsidiary layers and draw links between them, this uses a function which takes as its arguments the node name and its layer number (how far down the tree it is) and the number of items in that layer so far.
So I start at the first item in Layer 1 and there are as yet no layers below it. I start at the first one and add the first item in layer 2 then I kick the function off again and that adds the first item connected to item 1 in layer 2 in the layer below (3) starting at the first one, and so on. When I reach the bottom I go up one layer and add the second item in the bottom layer and so on. When I have added all the connctions to the first item in the next to bottom layer I go up one layer and add the second item connected to the first item in that layer and then add all the items connected to it and so on and so on.
In this way I build up the network exhaustively (to make things more complex more than one item in a layer may connect to the same item in the layer below).
I can do almost all that, the issue I am struggling with is I need to keep track of how many items there are in each layer (as some layer 1 items connect to 1, 2, 3 ...8 layer 2 items and so on). my idea is to keep a running total of these in an array LevelCount(1), LevelCount(2) etc. so when I add a new item to a layer I know where to put it. However I cant workout how to do this final step.
Currently I have a function that draws the nodes below a specified node this and takes the correct value from the array LevelCount(n) by passing Levelcount(n) (where n represents how far down the tree you are) into the function and the function then updates the value of LevelCount(n) (ByRef) so that next time I use it it is correct. That is fine but what I want to do is to is to call the same function from within itself when it adds each node which would make it work automatically - it would keep calling instances of the function until it reached bottom and then go back one step at a time to the top but I cant work out how to reference the right value in the array to pass into the second (and subsequent) instances of the function.
I don't think I can simply pass (n) into the function and in the body of the function set LevelCount(n) = LevelCount(n)+1
I also dont know ahead of time how many layers the model will have, nor can I tell which layer a node sits in as it depends on the links that are dynamically configured.
Beyond this a node can also be subsidiary to nodes in more than one level so it needs to sit at the lowest level - but I suspect if I can work out how to do the first bit i can do this too.

I have been struggling with a problem passing a small array to be used in a form and I hope that somebody can help me. I cannot get the array into the form.
In the main module code I have an array containing information on a book reference:
Private Function PresentForm1(ByRef iID() As String, sBookRef() As String) As Boolean
Dim iCounter As Integer
For iCounter = LBound(iID) To UBound(iID)
Form1.ListBox1.AddItem iID(iCounter)
Next
Form1.ListBox1.Selected(0) = True
For iCounter = 0 To 2
MsgBox sBookRef(iCounter) ' This bit works fine

Passing an array from a sub to another sometimes works, sometimes not. But when I call the same sub twice, it definately gets stuck at least at the second time. Seems as if I tend to lose some of my items of the array. And I cannot figure out why it happens, at what pace it happens or how I could stop this from happening.
1.Could it be that a control perishes as soon as it is set to 'ctrl.enabled=false'? 2.Or could it be that a declared array 'ary=array(tb1,cb1,frm1)' can not be handled without having had its items initialized with some lines of code, although the items visibly exist within the user form? 3. Can it be that a Sub 'remembers' the former values passed to it, if set to 'optional'?
However, I have added a cleared/minimized version of my userform as a file to this post, hoping that some of you out there might find the time to have a look at it.... I would really appreciate it. I have added the decisive parts of the macro below here, as well,
Private Sub UserForm_Initialize()
Dim elem As Variant
Dim wSht As Worksheet
Dim ctrl As Control
'set control arrays
'[...]
ctrlAllStep2 = Array(cbTimeOnly, cbIntensityOnly, cbAreaOnly) '[...]
ctrlAllStep3 = Array(tbIntensityTotal, tbIntensityBleached) '[...]
MsgBox "Two Controls exist now: 1." & ctrlAllStep2(0). name & ", 2. " & ctrlAllStep2(1).name, vbInformation, "Note: controls exist..."
'disable Controls in Step2 and in Step3....................

I will post my code and point out where the error occurs.
Sub GetProd()
'Averages Daily Production over the month
Dim WellRange, MonthRange As Range
Dim Month_ As Integer
TotWells = Sheets("R").Cells(1, 2)
TotMonths = Sheets("R").Cells(1, 4)
Month_ = Sheets("R").Cells(2, 4)
For Flag = 1 To TotWells
Set WellRange = DefineWellRange(Flag)
WellRange.Select <-----Used this To check If Range gets passed back properly.
For c = 1 To TotMonths
Set MonthRange = DefineMonthRange(Month_, (WellRange)) <---Error Here
Next c
Next Flag
End Sub ...
So the error occurs in the main "GetProd" Sub at the point when it calls the DefineMonthRange Function, its a 424 "Object Required" Error. Just before this is called I have a "WellRange.Select" which I was using to make sure that WellRange is in fact a range, and it does select the appropriate area.
So My question is of course, why I get an object error even though I am passing a range to a function which is expecting a range?

see the attached. The array formulas in B2:C3 are operating on the table in E2:F5. These are quite simple formulas as you'll see.
The formula in B3 is identical to that in B2 apart from the fact that the first array is wrapped in an IFERROR (there are actually no errors in the array, but that's not the point).
As you can see, the formula in B2 evaluates E3 as ="", and so the corresponding entry in F3 is ignored in the sum. Quite normal.
However, the identical formula, but with an IFERROR first acting on Array1 now evaluates the same cell as <>"", and so F3 is this time included in the sum.
What action has the IFERROR had on this array? Clearly, E3 is not an error, so a "blank" should still be passed, unchanged, to the function.
I have included identical versions of the formulas, but with Named Ranges replacing the actual range references. The reason is that, with these versions, if you step through the formulas with Evaluate Formula, for example with the formula in C2, you can see that Excel "temporarily interprets" the blank in E3 as a zero (this is nothing new, though I've never fully understood why it can't display a "" here as well) before then equating this "zero" as being a "blank".
Perhaps somehow, after being passed to the IFERROR, this "zero" is processed so that, when passed on, even though it still “displays” as a zero, for some reason it is no longer considered equivalent to "".

Passing Named Range into User Defined Function
MrExcel.com | Excel Resources | Excel Seminars | Excel Products mcm91201
Depending on time of day and computer I am sitting in front of I am using:
WinXP Pro SP2 with Excel 2003
Win7 Pro SP2 Excel 2007
Win7 Pro SP2 Excel 2010 on PC
Win7 Pro SP2 Excel 2010 on Mac Mini running Boot Camp
OSX Excel for Mac 2011
I have only tried this on Win7 Pro SP2 Excel 2007 but need it to work on all.
I enter the values 0, 1, 2 ... 89, 90 in cells A1 to A91
I select A1:A91 and name the range 'angle'
I create a user defined function:
Public function sindeg(value As Double) as Double
sindeg = sin(worksheetfunction.radians(value))
end
I want 'value' for the function in a cell to be replaced by the corresponding value in the same row (or column) in the named range 'angle'. For example (using commas as column separators). This works for Excel functions like sin, cos, radians, etc.
********** Worksheet Contents **********
A1 = 00, B1 = sin(radians(0)), C1 = sin(radians(A1)), D1 = sin(radians(angle)), E1 = sindeg(0), F1 = sindeg(A1), G1 = sindeg(angle)
A2 = 01, B2 = sin(radians(1)), C2 = sin(radians(A2)), D2 = sin(radians(angle)), E2 = sindeg(1), F2 = sindeg(A2), G2 = sindeg(angle)
A3 = 02, B3 = sin(radians(2)), C3 = sin(radians(A3)), D3 = sin(radians(angle)), E3 = sindeg(2), F3 = sindeg(A3), G3 = sindeg(angle)
......
A91 = 90, B91 = sin(radians(90)), C91 = sin(radians(A91)), D91 = sin(radians(angle)), E91 = sindeg(90), F91 = sindeg(A91), G91 = sindeg(angle)
Column A = input. Columns B, C, D, E and F all calculate the same value by row. Column G fails with a #VALUE. In row 1 the value of angle[1] = 0 therefore column D = C = B = sin(0) = 0. In row 2 angle[2] = 1 therefore B = C = D = 0.017452
How can I get the user defined function sindeg(value) in column G to accept the named range variable 'angle' like the Excel function radians(value) accepted it in column D?
This functionality should work horizontally as well as vertically. For example enter 'angle' A1 to CM1 then have sindeg(angle) filled from A2 to CM2. It should also work in the case where the named range 'angle' is a single cell.
I am sure that this is a simple variable type definition problem in my user defined function: should the input variable be defined as type Range? Or something more exotic?
The brute force approach is to have the function determine the input value by passing in the named range, working out dimensions, calculating offset between the cell the function is in and top (left) of named range, then counting down (right) to pick the correct value. However I cannot see adding all that code to EVERY function. Occam's Razor says there has to be an easier way since Excel built in functions seem to do it readily.

I'm using Excel 2003 and I'm trying to make my LINEST function and the source cells for a scatter graph use the cell range specified in another cell in the document. I figured out that it was simple to do the following:
I250 contains: 10, shows: 10
I251 contains: ="I"&I250, shows I10
But I can't figure out how to do this in a larger function. I've tried a few things but none of them work. Here is an example where I want it to do a LINEST with y values in cells Ja - Jb and x values in cells Ia - Ib (where a and b are integers specified in cells I250 and J250 respectively):

how to tackle a piece of work that I really don't want to do.
We have extracted some summary information on one of our products. The workbook has 10 sheets, one for each of our 10 main sales channels. Each sheet has the same layout of information on. There are 7 tables on each sheet, and each one cuts the data in a different way (eg one summarises by age of purchaser (in age bands), another by demographic group etc). Each table then has the same 14 columns of key data (eg number of sales, average order value).
I've been asked to analyse this information "for anything interesting". At the moment, the only way I can think to do this is to print out the 10 sheets, sit down with a highlighter, and try to visually identify trends and anomalies. The idea fills me with dread, and I suspect will be quite inefficient.
I've asked whether I can get the data in a pivot table or some other format that might be more conducive to analysis, and have been told no. (There will easily be more than 100,000 lines in the original data (we're using Excel 2003)). To be honest, I'm not sure that I'd really be that much better off, even if it were in a pivot table.
