Store / Retrieve Arrays Within Single Cell?
Aug 31, 2012
I have created a number of complex functions that use or create 1-dimensional numeric arrays in VBA, and I would like to store and retrieve some of these arrays within single cells of a worksheet so that I can use them in dependent functions without having to store and display the entire array with one element per cell, and without having to recalculate the same intermediate array multiple times within VBA.
Are there any existing worksheet or VBA functions (or is it possible to create two functions) that can convert and store an entire numeric array within a single cell of a worksheet (e.g., as text), and then convert this back into a form which can be read and recognized as a numeric array by another function?
Or is there any other way to avoid filling my worksheet with arrays, or having to recalculate them each time within VBA?

I have {1,2;3,4} in *one* cell, and {9,7;8,10} in another cell. How can I sum those arrays? The result may be in one cell, or in a 2x2 range. Plain Excel, no VBA.

I have 2 sheets recording feedback and summarising the overall percentages for each trainer.
My boss wants me to do this by month!?!?!
I have created a third sheet but I am not sure how to do the following:
Look up the trainer name
Look up the month
identify the percentages for each category
create an overall average of these percentages
So for example if Jon smith trained twice in JAN getting 100% and 50% in cat1, it would display 75% in the cat 1 cell and so on.

Look at the tab "testing-allproduct" cell C2. If that value exists in the tab name "store-allproduct", cell c2, then take the value from "store-allproduct" cell a2, and put that value into "testing-allproduct cell" A2.

I am retrieving a CSV file from the net. In this file there are 'x' amount of row data and 7 columns. I only care about the values in the 7th column for each row. I also don't care about the entire first row. A graphical version would be represented something like this, with the values I want colored in orange:
|---,---,---,---,---,---,---|
|---,---,---,---,---,---,---|
|---,---,---,---,---,---,---|
|---,---,---,---,---,---,---|
|---,---,---,---,---,---,---|
|---,---,---,---,---,---,---|
|---,---,---,---,---,---,---|
.
. extending until the end of the data set
.
I've managed to dice this thing into a jagged array by first splitting it using vbLf as a delimiter, and therefore adding those to an array called Lines(). Then I split Lines() up using commas as the delimiter and threw those into a jagged array, let's call it Breadcrumbs()(). I want to throw all the values from Breadcrumbs(i)(6) into an array of its own. Here's my code so far:
Code:
Public Sub CSVparser(file As String)
Dim Lines As Variant
Dim j As Integer
Lines = Split(file, vbLf)
ReDim breadCrumbs(UBound(Lines)) As Variant
For i = 1 to UBound(Lines) - 1
breadCrumbs(i) = Split(Lines(i), ",")
Next i
End Sub

I'm sure this is a very easy question, but I have been having trouble finding the answer on this and other forums.
Our macro has a search routine where it looks through a column for particular cell contents. Once those contents are found, we want it to save that cell's location, go do something else, and then return to that location afterwards. How would we go about doing this?

What I am trying to do is during a loop operation, which subtotals variable ranges, I want to store the locations of the cells that it puts the sum function into. I.E. if based on criteria it determines that range E4:E12 is summed into E13, I need to save E13 to use in a formula once I'm out of the loop. I don't know how many instances it will find and there's the possibility in the future that not only will the number of instances increase, but the location could always be different as well. Any way to do this without a million lines of code.

1. Store the value in Cell A1 to a text file located in C: with name TEXTFILE.TXT (Replace the existing value)
2. Store the value to the text file as additional line item (append records)

way to store a cell's location to variables.
Something like:
int a, b
Cell(a, b) = ActiveCell
I'm currently working with a fairly large worksheet, and I'm using Cells. Find to look for a specific cell. Then I want to Filter that column, but I can't figure out what column Selection.AutoFilter Field:=? should be.

I would like to record the address of the last set of cells that data was input into to a variable so that a user can choose to delete the last entry. An 'Undo' button really.
What I have is a user form that writes different materials to thier respective sheets in the database. (Material1, Material2, etc.) Some materials have a different number of variables (some have a width and some don't, but all have a quantity.)
This is the code I have for adding the material to the database (each material has it's own button with material specific code.)
Private Sub AddToMaterial1_Click()
Set c = Worksheets("Material1").Range("a65536").End(xlUp).Offset(1, 0)
Application.ScreenUpdating = False
c.Value = Me.Material1Quantity.Value
c.Offset(0, 1).Value = Me.Material1Description.Value
c.Offset(0, 2).Value = Me.Material1Length.Value
Dim lastenty1
lastentry1 = c.Address
Dim lastentry2
lastentry2 = c.Offset(0, 1).Address
Dim lastentry3
lastentry3 = c.Offset(0, 2).Address
Dim lastentry4
lastentry4 = c.Offset(0, 3).Address
Dim lastentry5
lastentry5 = vbNullString
Dim lastentry6
lastentry6 = vbNullString
Application.ScreenUpdating = True
End Sub
The following code is what I am trying to do for a single button to clear the last entry to the database.
Private Sub RemoveLastEntry_Click()
Range(lastentry1).ClearContents
Range(lastentry2).ClearContents
Range(lastentry3).ClearContents '(There is always at least 3 cells to clear)
If lastentry4 = nullstring Then Exit Sub
Range(lastentry4).ClearContents
If lastentry5 = nullstring Then Exit Sub
Range(lastentry5).ClearContents
If lastentry6 = nullstring Then Exit Sub
Range(lastentry6).ClearContents
End Sub

I am trying to use the Indirect function to use the value in a cell to select a sheet with the same name as the value of said cell. I have looked at several posts and attempted multiple methods. I still get an error. I cannot find a thread describing exactly what I am trying to do, which is:
reference a cell value to direct the formula to the correct sheet to then complete an array Sumproduct formula.
Since this description barely makes sense to me reading it, I have attached an example. The problem is in cell C7. Basically, I want cell c7 to look at cell c1 and then go to the tab with the matching name as cell c1 and complete the calcuation.

I do data entry for a webstore and one cell is used to map out the exact product category/subcategory path. I currently have to copy the appropriate path from a long list on one page and then paste it into the cell. I have to do this a hundred times a day. It would be nice if each cell within that column can have these values stored in them so I can just click on the cell and open up a drag down box and select the needed value. Is this possible to do in Excel?

I have in column B, cells that have any number, one number or several like B2.
#
A
B
C
D
E
[Code]...
Thinking that I have a loop for rows 1 to 3:
When in column "A" is "No", I want to consider values in C and D to get:
Code:
a[1]=Cells(1,"C") & "-" & Cells(1,"D") & "-" & "ABC"
But when in column "A" is "Yes", I want to store in array each value within cell in B (in this example B2) to apply later a For/For Each
over each number (in this example are 3 values only within cell B2), something like:
Code:
a[1]=Value_In_B2[1] & "-" & "ABC"
a[2]=Value_In_B2[2] & "-" & "ABC"
a[3]=Value_In_B2[3] & "-" & "ABC"

I am having trouble using the find function. I need to store a date as a variable and then find this date on another worksheet. The date is in the following format:
dd-mmm-yy
This is what I currently have which gives me a run time error 91:

Dim DateSearch As Date
DateSearch = Range("C3").Value
Cells.Find(What:=DateSearch, After:=ActiveCell, LookIn:=xlValues, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _

I have a table in which I have a "patient" column and a "page" column. The macro searches for a patient's number, then looks if this patient has the page "900.--". A patient may have more than one page, which will result in many rows with the same patient number. So far, my macro uses the search function to find a patient number, then compares the cell next to the active cell to see if it contains the page "900.--". If not, then my macro searches for the next patient and so on until the page is found and noted into another workbook or none is found.
In order to stop the loop, I am trying to store the address of the first cell found into a variable "rFirstCell" so that it can later on be compared to another variable, "rSecondCell", which represent the active cell. When both are the same, it means all the available search results have been tested and the loop should stop.
Sub testing()
Dim rRng As Range, rFirstCell As Range, rSecondCell As Range
Set rRng = Worksheets("Overview").[a1]
Dim sDeath As String
sDeath = "death"
ActiveSheet.AutoFilterMode = False
If LCase(rRng(2, 15).Value) = "x" Then
If LCase(rRng(2, 9).Value) = sDeath Then
Workbooks("DM Endpoint pages_test.xls").Activate
Range("A1").Select...........................

I have a worksheet where some cells contain a comment. I don't know beforehand how many of those cells are present, nor their address. I want to write a macro that stores the values of only the cells that contain a comment into an array (of course the size of the array is not known beforehand). This should be done by scanning through those special cells in a given order (by rows, by columns, whatever).

How to store a value in variable after concatenation of two values and putting it into the same cell.
Let assume, in cell A1, we have value 1 (numeric). And in code i have a variable with stored value as "%".
Now i want to concatenate 1 and % and put it back into cell A1 as 1%.
I have a written a code, but seems to be wrong one.
Sub Percentage()
Per = "%"
lr = Sheets("Process Overview").Cells(Rows.Count, 3).End(xlUp).Row
For i = 10 To Sheets("Process Overview").Cells(Rows.Count, 3).End(xlUp).Row
If Cells(i, 4).Value = "p" Then

I have a spreadsheet with near 300 tabs, each with a picture in the tab. The main tab has a list of all other tabs, the goal is to allow the user to click on a cell next to an entry, and have Excel flash the referenced tab to allow the user to see what the entry is referencing. I have written a simple macro that activates a desired tab, unhides it, displays a message box to pause the macro, rehides the tab, then returns the user to the main tab.
Rather than creating a macro for all 300 tabs and creating buttons I would love to use the Private Sub Worksheet_SelectionChange(ByBal Target As Range) or some variation thereof, to make my life much easier. The name of the tab is in cell A2, so I would want to have the user click on cell A1, activate the macro, then take A1 to A2 with something like A1 = A(x+1)->A2, then display the tab listed in A2. So rather than have 300 macros with Sheets("XYZ").Visible = True, I would love it to read Sheets(contents of referenced cell).Visible = True. with the contents of referenced cell coming from some manipulation of the cell I clicked on...

I am trying to loop through column A and I want to store in an array where I find "App" within the cell value. I am trying to find "App" but will store the whole cell value in the array. I could not figure out the Find method, so I tried the MID function but am having no luck.
Here is my code:
Code:
Sub Arraytest()
Dim arr As Variant, lastrow As Long, i As Long, f As Long, l As Long
f = 0
lastrow = Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).Row
ReDim arr(1 To 1, 1 To lastrow)

I get a report each day with a list of issues. the "group" that works the issue and the "priority". Based on these two factors, i need to do a double lookup (vlookup?) to another tab or file to match the priority and group and see what value should be brought back for each lines results. For example, if group1 had a prority3 issue, the lookup would find the value from the other sheet or file and bring back the value and put it at the end of the row where the formula is.
Attached are examples of the sheets.

I was just wondering if it was possible to only allow cells in a worksheet to only allow values that are a combination of 2 arrays whether it be through data validation or other means. For example, if I have an array that has a b and c and a second one with 1 2 and 3, is it possible to only allow values a1 a2 a3 b1 b2 b3 c1 c2 c3?

Is there a way I could achieve copying cell's content minus some characters?
For example in the cell A1 would be: "two apples"
I would put into the B1 cell something like =A1(-4charactersincludingspace) - the result in B1 should be "apples"
Is it understandable what I mean?

I am trying to get a formula that will return the immediately adjacent value to a cell that is "lookup-ed". However, the Lookup cell is not in a constant column?
I tried Vlookup though this needs to specify a column, however i don't know the column until initial data is entered. if there's a formula that enables something along the lines of the 'thelookup cell plus one" that would likely work?

How would one retrieve an email address in a cell if it appears randomly ?
In Cell A1, let's say the content is:
Hi My name is Peter, my email is peter@mrexcel.com
In Cell B2, let's say the content is:
Good morning, you can reach me at isabelle@yahoo.com
What I was thinking is maybe start by finding the @ with =Find("@",A1) this will give me the position of the "@".
How can I tell excel to give me the string before and after the @?

I have a large table with data to which I want to retrieve a name to the left of a certain cell.
Clear as mud so far!
I've put together a small example of what I'm after. In cell F9 is the MAX of cells F2:F7. In cell H3 I then want a formula that will find the MAX of F2:F7 and return the text five rows to the left of that cell. In this example it would be Fred.
The second part of this question is how could I get it to display if more than one person had the same total....
