Read A Range Into An Array

Aug 10, 2007

In a Worksheet named "Input" and in Cells "B3:G?" I have 6 number groups. How can I ...

( 1 ) Put each of the 6 number groups into an array when I don't know what the last row number is.

( 2 ) Find the maximum value in any of those cells and attach it to a variable named MaxVal.

... so once I have done this I can then loop through each 6 number group and perform some calculations.

Object Required Passing Range To Function

Sep 28, 2007

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?

Passing Named Range Into User Defined Function?

Dec 4, 2012

Passing Named Range into User Defined Function | 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))

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.

Passing Array To OFFSET - Array Height Parameter

Aug 5, 2014

I want to pass an array to Offset in the "Height" parameter, without having to type the array.


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)??

VBA Custom Function To Sort And Average Two Numbers Of A Range

May 7, 2013

I need to create a custom function that can do the following without modifying the selected range. If I have data in a row, I need a function that can give me the following result:

Original unsorted data:


The custom formula will not modify the selected range, and after saving it or copying somewhere and sorting it, it will provide the following result: if N or count(range)=5 , and p=1, average(second and third smallest values of the range)=34; and if N=4 (lets say that we errase the number 1 data point in the range), average(third and fourth smallest values of the range)=67.5 So it is basically a sort and then getting the averages of specified row numbers depending on N or count(range) Here is what I have.

I'm missing how to create a variable with the sorted range and how to use an index to refer to the rows I want to average:

Function CSORT(r, p)
'rs or something similar that will contain the sorted range r
Dim rs As Range
'Sort rs (The following line one doesn't work, so I need one that does)
rs = Application.Range(r).Sort
Dim p As Integer

Return Cell Address That Falls Within A Range Of A Custom Lookup Function

Jul 3, 2009

I am performing a lookup using the populare user defined function nlookup, which does not take a lookuparray argument to find lookup values. But I only want to return lookup values that fall into a certain array. To accomplish this, I figured out that I need a way to specify a condition of the type "if cell address of lookup value falls within range"

It should be possible if I find a way to return the cell address of the nlookup value, but as nlookup is not limited by a lookuparray argument, so I was not able to use the address/index/match that come up in similar questions.

Passing Array Between Userforms

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?

Passing Array Variables In Functions?

Sep 15, 2012

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.

Passing Array Losing Items: Lost 'control'

Mar 9, 2007

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..."

Autoselect Range/Row Reference For Linest Array Function

Dec 31, 2007

I have set up regression in excel using the linest array function which automaticly updates whenever the data it is references changes. Currently the formula in K3 =

Only the Y range in column K changes and then the formula automaticly recalculates the regression parameters. However sometimes the range of valid data changes with each new update so currently K8 to K50 contains valid values and so the formula works. But if the range of valid data now ends at say K45, and the remaining rows (K46- K450) contains #DIV/0!. In this case the formula does not work and I need to go in manualy into K3 and reselect the range to get it to work (in the baove case to =LINEST(K8:K45,M8:N45,TRUE,TRUE)

Is there anyway I can get the formula to update the range (the number of rows to use) in the calculation automaticly so I don't have to go into the formula in K3 and change the range manually everytime the data changes? Basicly I like to use all rows in column K (from K8 to K50) where there is a values and ignore cells with #DIV/0!

I'm guessing the easiest way to do this would be to set up a dynamic range of some sort that feeds into the linest array function so that the end row reference for columns K and M & N changes depending on where the first #DIV/0! occurs in column K.

Read Entire Row Into An Array

Oct 9, 2007

I have a workbook with about 700 rows and about 40 records on each row. about 2-7 a day of these.
The procedure I currently use a loop for does 2 different things.

1 I collect only a few of the records from the line and place them in a separate sheet .I collect the individual data, identify the ID ( cell F) and then search for the corresponding ID on a nother sheet when I do find it I add the info to the sheet on the last + next row. (I sort later)

2 I collect the entire row and place it on yet a nother sheet.
The whole row has information that is categorised by the content of Cell A (name) so I copy the row and paste it into a separate sheet.

What I would idealy like to do is to copy the entire source sheet into an array once, and then copy the data into each target sheet using a loop to get each record from the array. Using only 1 loop to first read the separate data from the " array row" and place it into the first target sheet (procedure 1) and then switch the workbook and copy the whole "array row" into the target sheet there (procedure 2).

At the moment I read info on 1 row switch to the target sheet and place the information there, then I "copy" the row and switch to the next workbook and paste it there then I go back to the source and do the next row.

Obviously Im no programer and that was the best way of doing what I didnt know how to do better .

Is there a way that a whole row can be stored in an array and then 'copied' onto another row on a nother sheet without reading in the individual cells into separate elements. That would be the worse case scenario but a much faster way of doing what I curently have.

Unable To Set Formula Array Property Of Range Class - Using Replace Function

Mar 3, 2014

I'm looking to loop a comparison code. I'm using dynamic referencing (using x and y) to find maximum values for specific time intervals. The code works on a cell to cell basis, meaning if I input the formula and change the cell referencing manually then the equation will give the desired results. However when I attempted to create a VBA code to speed up the process I kept getting a 1004 Unable to set FormulaArray Property of the Range Class error, I later figured out that the Formula Array function is limited to a certain number of characters so I split up my function into 3 different string formulas. I still get the same error.
