Accessing Elements Within Arrays
Nov 10, 2009I've been teaching myself VBA for the purpose of processing some time resolved data from an instrument. I've come up against a problem and I just can't work out why the code is failing. (using excel 2007, VBA 6.5)
I declare some arrays as dynamic, then ReDim them to a user defined number (with Option Base 1) and input data from a spreadsheet into the array. I can then output the data into the spreadsheet again and the lbound and ubound functions return the correct values for the array. What I cannot do is actually access individual elements. If I specify array(i) I get the "Subscript is out of range" error. The code relevant to this problem is as below (simplified as there are more arrays):
Reference Individual Elements From Non-Contiguous Range Name
Jun 29, 2012I have several tables on one sheet, each of which has a Grand Total value at the bottom right of the summed data range
I have manually selected (using ctrl + left mouse click) each Grand Total cell and defined all these cells as a Named Range called Grand_Totals
I thought it would be possible to reference each of the cells in the Grand_Totals range individually.
The =Index function works fine if the data is contiguous but I can't figure out how to get anything other than the first element of the Grand_Totals range
So for example
Lets say the cells of the Grand_Totals non-contiguous named range are F10,N10,F30,N30,F50,N50
How would I reference the third element/cell (F30) in this range. I should point out that I actually need to reference all the cells in the Grand_Totals range and the range has a lot more than 6 cells
Nested Looping For Comparing
Mar 31, 2007I'm working on a VBA program to find matching data which will work something like this;
ColA = DocumentTitle
ColB = Filename
ColC = ReferenceNumber
an oracle database stores a list of Documents, I have already written the code to pull the needed DB columns into excel as ColD,ColE respectively. it gets tricky here because ColA needs to find a match in ColD and then compare ColB to ColE (on the same rows as ColA and ColD) and if they match ColC's cell will change to green to show a match. Alternately Colc can be thrown into ColG as a flag... I'm not sure what is easier, color would save on cells and is all that is needed. I can think how how it should work, but I'm new to VBA programming and am having difficulty doing the full comparison the way I'd like.
Mod Function For Comparing Looping Values

Slicing And Dicing CSV Files - Involves Arrays And Jagged Arrays
May 8, 2013I 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
VBA Code To Get Individual Values In A List Placed Into Individual Cells
Apr 7, 2014My current project involves sorting a spreadsheet, selecting specific qualifying data from the sheet, storing it into a variable, the pasting the individual values from the list into individual cells on a different sheet within the same workbook. Here is the code I have so far...
Code:
Sub Test()
'' freeze screen updating to remain on main worksheet
Application.ScreenUpdating = False
'' move to Avaliable worksheet
[Code] ..
When this code runs the first item in the list pastes into Sheet10 A1, but no other values from the list are placed into Sheet10. Previous to this I had been using a variation of this code to push the list into a combobox list within a userform. In that case instead of
Code:
ThisWorkbook.Worksheets("Sheet10").Range("A1") = x
I had
Code:
Combobox1.list = x
And this worked perfectly; creating a list within the combobox (in fact I can use this modification to interrogate my code to determine if the list is being properly generated, and it is).

Empty The All Elements In An Array
Dec 11, 2008If I have say several hundred elements stored in an indexed array and I want to clear them each time the sub or function holding them is called, is there a way to erase the contents of the entire array without having to loop through each element.
Something like array().clear? Note that each time the sub is called, they are also redimed to some reference.

View 3 Replies View RelatedRemoving Duplicates With Less Elements In A Row
Nov 22, 2011Writing macro for "Removing duplicates with less elements in a row."
I am trying to remove duplicate entries from a file based on the number of data present in a row. Please see below
Example:
Name Col-1 Col-2 Col-3 Col-4
abc 1 3 4
abc 1 2 3 4
abc
abc 1 4
I want to retain the row with maximum elements(row 2 in above eg.).
Result should be:
Name Col-1 Col-2 Col-3 Col-4
abc 1 2 3 4
Currently I am doing this manually, by adding countA at the end of each row, then arranging them in descending order. That will make sure that the row with more data comes first n hence gets retained, while other rows gets deleted.
Can this be done using Macro?
Below macro just deletes the rows,
Public Sub DeleteDuplicateRows()
Dim R As Long
Dim N As Long
Dim V As Variant
Dim Rng As Range

View 9 Replies View RelatedRank Elements Of 2D Array
Sep 1, 2007I am trying to present a 10X10 Matrix Range (A1:J10) full with UNIQUE INTEGER random numbers. I thought to use an Single Dimension Array (100 deep) and fill it with the Rnd() Function.
Then, I thought to check the RANK of each element of that Array and transfer it to 100 cells (10X10) in the Sheet (assume A21:J30) with the help of 2 nested loops.
My problem is: How to find the Rank of each element within ARRAY1. Is there a way to refer to an Array as to a Range in a Worksheet. (I do not want to transfer 100 values from the Array to the Sheet - I rather prefer to check the Rank WITHIN(!) the Array).

Address Elements In A Range In A Formula
Mar 1, 2009I have a named range, called 'event' relating to cells a2-a200, I have a named cell, 'eventcounter'. I was hoping that I would be able to use the named cell eventcounter in formulae on the cells in the event range rather than having to use the cell address. So instead of having a formula that was something like this, =if(a3= etc etc.
I could refer to the range event and eventcounter. Eventcouter gets its value simply by counting the number of non blank cells in the event range, so consequently - I can only figure out how to address the last entry in the event range in the manner that i wish.

Deselecting Selected Elements In A Listbox?
Oct 25, 2013I have a listbox on a userform, with multiselect set to 2 (Multiselect extended). When the listbox is displayed for the first time, no elements are selected. At a certain point in this application, I want to get back to the original state and deselect all items.
I do that with the statement Listbox1.listindex=-1. I hope that is the right thing to do. However, the elements that originally were selected are still blue-coloured, like they became when the user selected them. How do I do to make them look deselected?
It also seems to me that the array Listbox1.selected(x) still holds the value "true" for elements that were selected. Is it so that in addition to say listbox1.listindex=-1, you have to loop through the elements in listbox1 and set all of them to false?
How To Select Last 90 Elements In Filtered Column VBA

Column A is the key where i filter between a lot of duplicates
If i filter on X100000 there is about 432 elements (rows)
if i filter on Y100100 there is only 43 elements (rows)
The problem is i only want to copy the last up to 90 element to another sheet. I can copy all 432 rows to a second sheet and then copy last up to 90 rows thats what im doing now. And i am familiar with
"Selection.SpecialCells(xlCellTypeVisible).Select"
But still cant figure out haw to do it directly in the filtered sheet.
