Algorithm To Sort An Array Of Data In Vba

Jun 4, 2007

Im looking for an algorithm to sort an array of data, deleting multiple values whithin the array and shifting the values down the array to leave no gaps. the crude set of loops i am currently using is:

For f = 0 To 100
For g = f + 1 To 100
If LineArray(g) = LineArray(f) Then LineArray(g) = ""
Next g
Next f

which does work and serves my purpose but is messy as it leaves blank gaps in the array.

Sorting Algorithm Doesn't Sort As Needed

Dec 2, 2009

I have this module that is supposed to look in column A and if it sees duplicates it looks in column B (with the date) and erases the entire row where the date is older in column B. I am attaching a sample to better illustrate it.

The highlighted in yellow rows are were I have duplicates and I want the row where the date is in red border to remain.
The module I have so far erases the newer records instead of the older.

This is the file:

Array Cannot Allow To Sort Data?

Jun 30, 2014

Excel file. The file has two tabs: 'Input' and 'Master'. The 'Input' tab is for users to input any new records, and the 'Master' tab is to retrieve data from the 'Input' tab. Given that some users may want to insert a row in between (rather than add at the bottom).

I used arrays in the 'Master' tab such as:

={IF(ISERROR(1/Input!E2:E250),"",Input!E2:E250)}

Now there came the problem: in the 'Master' tab, the data cannot be sorted when the arrays are used. Otherwise, there is a warning message: You cannot change part of an array.

Sort A Array Formula

Sep 27, 2009

On from a solution I am using in the sheet which uses very well an Array Formula.

In the attached book I have a sheet with a bunch of tables called Site Table. In the sheet called Working Sheet I want to get the text Site Names and list them in Column A. Sorted would be nice not required but I can't think of way to avoid blanck rows without a manual sort. I tried many versions of Find without a solution as well.

Range Array Sort

Oct 20, 2009

I am trying sort a bunch of different ranges. So I am trying to use the same sort code but run an array of ranges through. This code is for only two ranges
CA3:CD200 and CF3:CI200. I want to pass the ranges as variables through the sort code but I cannot get it to work.

Sort An Array In VBA Memory

Jul 11, 2007

two parts:

1.
The following is the VBA version of what i've been using:

Range("A1:J1000").Sort Key1:=Range("D2"), Order1:=xlAscending, Key2:= _
Range("E2"), Order2:=xlAscending, Key3:=Range("F2"), Order3:=xlDescending _
, Header:=xlGuess, OrderCustom:=1, MatchCase:=False, Orientation:= _
xlTopToBottom, DataOption1:=xlSortNormal, DataOption2:=xlSortNormal, _
DataOption3:=xlSortNormal
now arrays are bigger than 1000 rows>> even bigger than 65536.

Such an array is stored in "arrBIG" and dimed as (1 to 10, 1 to 100000). The goal is to sort it by the 4'th, then 5th then 6th values in the first dimension - the one that is 1 to 10 - i call this the column.

arrBIG.Sort Key1:=4, Order1:=xlAscending, Key2:= _
5, Order2:=xlAscending, Key3:=6, Order3:=xlDescending _.................

Sort String Array

Nov 18, 2006

I have a string (PreString) that gets its values from a procedure call (PreResult). The string consists of 4 values for each loop which I then split into the y array.

I then want to transpose the array to the worksheet for sorting.

I don't really get the transpose to work as I want to. I want every 4:th y to be printed on a new row (x). I don't really know how to use the Ubound function to get it right.

Should I make a 2 dimensional array instead ? If so, how is that made ?

Dim x As Integer, z As Integer
Dim var_Status As Integer
Dim var_Week As String
Dim var_HoursPerWeek As Integer
Dim PreString As String

i = var_StartWeekNr
j = var_RangeNumberOfWeeks
z = 0
x = 0
var_Status = 0
var_Week = ""
var_HoursPerWeek = 0
PreString = ""

Algorithm For Addition (operation For Each ID)

Sep 25, 2009

Have an excel table with following data:
- ID
- number of bottles
- number of bottle crates (there are 20 bottles in one one bottle crate)

201688194000bottles
20168819200crates
2016883812000bottles
20168838600crates
201688396400bottles
20168839320crates
201688809000bottles
20168880600bottles
20168880480crates...................

I need to write a macro which will do this operation for each ID:

(bottles/20)-crates = x

and if "x" is not 0 then write down the value of "x".

There are two points I would like to point out:
- One ID may contain 3 or more rows (see 20168880)
- The macro will work with hundreds IDs so the algorithm should be fast (but it is not necessary)

Create Array Of Variables And Sort

Nov 12, 2006

I have a dynamic number of rows each with three colums of values. These varaibles I want to fill an array with but I don't know how.

Now I've just "concated" these three variables into a string and then I intend to split the string into rows by the third comma. (see below)

I think it's easier though to use an array and I really appreciate some assistance. Please tell me also the best way to sort the array. It will be sorted by var_Status which is an integer. (sort order: max positive to max minimum)

PreString = PreString & var_StartWeek & ", " & var_Status & ", " & var_Totalh & ", "

Sort Array In Macro Code

Jun 7, 2008

I have been trying to take a variant array that has 6 columns, output it to a new worksheet (although I would prefer to just sort the array but can't get that working - how I can do this please feel free), sort the worksheet by 2 different columns, and then move these values back into the original array. I think I have the dumping and sorting down but I can't figure out the putting back into the array part. Here is the code I have thus far. varRecords is the array I am dumping to the new worksheet.

Dim dumpSheet As Worksheet
Set dumpSheet = Sheets.Add
Range(Cells(1, 1), Cells(1, UBound(varRecords))) = varRecords
Range("A1:F" & numRows).Sort Key1:=Range("C2"), Order1:=xlAscending, Key2:=Range _
("A2"), Order2:=xlAscending, Header:=xlGuess, OrderCustom:=1, MatchCase _

Table Showing A Basic RSA Algorithm

Apr 8, 2008

I wonder could anyone help me with a problem i'm having, I have a table showing a basic RSA algorithm in excel, for example,

M 13 2197 19 8893887173 13 M
N 14 2744 5 788125 14 N

etc etc,

How the numbers are derived isn't important, what i want to do is create a visual basic form, to allow a user to input a letter, for example M in a text box, click a button, and then the 5 related digits are shown.

So the user inputs M into a text box clicks a button, then 13, 2197, 19, 8893887173 and 13 is output to 5 other text boxes.

Math Algorithm To Solve Puzzles

May 30, 2006

Given a list of numbers and a list of 'allowable' operators, come up with a specific total. ("The numbers game" on countdown on BBC2.... ooooh Carol Voderman)
For example, given the numbers 1, 3, 4 and 5 with valid operators +, -, /, * come up with a solution equal to 15. All numbers must be used once only. Use operators as often as required. The specific example above was given to me and I personally think its not solvable (might be a practical joke). But I am wondering is it possible to prove this through assertions or develop an algorithm to solve such puzzles. I can get 14 and 16, but not 15....

Using Array Formula To Sort Alphabetically Over Multiple Columns

Feb 14, 2014

In the attached example file, I have two tabs: options and sets. The options tab is to be populated from a form. The sets tab is to draw data from the options tab to create teaching sets. I have managed to create an array formula that does this for me, but what I would like it to do is sort my resulting list alphabetically. For reasons that I won't go into, I need the data on the sets tab to remain in three columns: First Name, Surname and Form.

This is the array formula I am using at the moment: AliGW - Example.xlsx

Speeding Up Macro Process (Graph Algorithm Stuff)

Jul 7, 2009

i'm working on floyd algorithm macro for a project,
problem is, the spreadsheet matrix is huge, it's a 1043 x 1043 spreadsheet
And this is taking wayyy too long, i've been waiting for almost 2 days already..
here's the file :
http://ifile.it/6v2j39f
(You start the macro using "run" command in "input" sheet)

So is there any way to speed it up?
Or if anyone got a supercomputer, could you help me process this? :p

I'm thinking about changing the 10^5 value into infinite value, but i can't find a way to display infinite value..

And here's some reference for Floyd's algorithm,
http://ifile.it/12p5zle

I have tried to split the algorithm to make it process one iteration at a time, but i've been waiting like 2 hours with no result,
and that's for 1 iteration, can't imagine how long it takes for 1043 iterations
You can do this by deleting the.

Formula / Algorithm For Identifying Minor Changes In Text Strings?

Feb 17, 2012

I have a database of approximately 250000 email addresses and I would like to see if there is some way to use Excel to analyse the strings in order to identify potential 'non-unique' individuals.

For example, if I have the following email addresses:
12345@example.com
12346@example.com
12347@example.com
or
example1@example.com
example2@example.com
etc

Is there some way of extracting common text strings, lets say where there is a difference of 1 character / digit between strings (rather than alphabetising and searching manually)?

Display The Path Result From A Floyd Algorithm Matrix Output

Aug 8, 2009

I want to display the path result from a Floyd Algorithm matrix output..

You can download the excel file here : http://ifile.it/lw4tgic
It consists of 1044 nodes, and we need to find the path between 2 nodes for ALL pairs..

Now, to find the path between 2 nodes, we need to :
1. Find the resulting cell of corresponding 2 nodes (y to x = z)
2. Update the path with that value (y z x)
3. For all the direct pairs in the current path (yz, zx), find the resulting cell
4. If destination (x) not the same with result (z) then repeat step 1 for that pairs.
5. repeat until x = z for all pairs.

Maybe it's better if i use an example....
we'll use T01 to E78 as an example

T01-E78 = if you look in the table,
y (vertical) = T01,
x (horizontal) = E78
z (result) = E77, so

T01-E78 = E77, so path = T01-E77-E78

check if result of T01-E77 = E77 (x = z?)...........................

Extract Unique Distinct List From Two Columns With Array Formula And Sort From A To Z

I have two lists in different columns, which are defined ranges. I want to extract them to a unique list with an array formula and at the same time sort albafetically, without duplicates, like this:

List1
List2

Final List

Audi
Ford

So far, I have this formula which is working in what concerns removing duplicates and exctract a unique list. But it is not ordering alfabeticaly.

{=IFERROR(IFERROR(INDEX(List1, MATCH(0, COUNTIF($D$1:D1, List1), 0)), INDEX(List2, MATCH(0, COUNTIF($D$1:D1, List2), 0))), "")}

Looking Up Row Array Data In Column Array

Jul 11, 2007

On one sheet (KPI) I have either the values "x" or "" in the range A84:A89 to mark wheter to use the corresponding project in the range B84:B89. On the sheet X-ref I have the same project names in range T4:Y4 and a corresponding target value in T8:Y8

What I want is the sum (or average) of the marked-projects target-values. The result should end up in KPI!G31.
In other words I want

=sumif(A84:A89;"x";'X-ref'!T4:Y4)

but it doesn't work since the first range is an column-array and the second range is an row-array.

Excel 2010 :: How To Filter / Sort Data Based On Partial Match Of Data In Cell

Apr 16, 2013

I am using Excel 2010. I am a novice user.

I have a lot of data to filter / sort. I want to initially to create a filter for a column of data - which has the format similar to hierarchical paths to files. The data is a mix of text/numbers. e.g.

pathA/path_X/path_Y/path_Z/lso0_rxs_reg_254__5_0/d
pathA/path_X/path_Y/path_Z/lso0_rxs_reg_253__5_0/d
pathA/path_123/path_456/data_out_reg_17_0/d
pathA/path_123/path_456/data_out_reg_0_0/d
pathA/path_X/path_Y/path_Z/lso0_rxs_reg_255__5_0/d

[Code] .........

Doing an alphabetical sort of this date would return the following order. As you can see while each strings in unique - there are many instances where they are simialr - if you ignore the unique numeric values at the end of the string.

pathA/path_123/path_456/data_out_reg_0_0/d
pathA/path_123/path_456/data_out_reg_17_0/d
pathA/path_123/path_456/data_out_reg_4_0/d
pathA/path_X/path_Y/path_Z/lso0_rxs_reg_230__6_0/d

[Code] ......

So what I want to do is to create a filter for the strings - but ignoring the numeric bits at the end i.e.

reg_[0-9]+_+[0-9]+/d

The strings are obviiously of varying length and the number of hierarchical paths is different, so I can't split string on "/".

Similarly folder paths names can contain "_" so can't split string on this either.

As I don't know how many "/" or "-" instances there will be in the string I don't believe I can use the find function. Also as the amount of number will be different i don't think I can use =right(a1,X) either.

I may be able to search for the pattern above - as this is probabay unique - so maybe it's something like the following pseudo code:

Function GetString(txt As String) As String
With CreateObject("VBScript.RegExp")
.Pattern = "reg_d+(_)+d+//d"
GetString = .execute(txt)(0)
End With
End Function

If I do require VBA code - how do I then use this for creating a column filter? Or will I have to extract the filtered data first from the column (and its associated row data) into another worksheet to use?

Once I have the filter in place I want to create tables using the filtered data - so for example each column value above has a lot of associated data values in each row e.g

26 pathA/path_123/path_456/data_out_reg_0_0/d
32 pathA/path_123/path_456/data_out_reg_17_0/d
8 pathA/path_123/path_456/data_out_reg_4_0/d

So my table would show the name "data_out_reg" and the range of values 8-32

Automatically Sort Data And Ranking Based On Sorted Data?

In the attached spreadsheet I track the performance of my team. I enter the AHT for my team in the work sheet named "AHT Summary".I keep updating this data every month. automatically sort the updated data and rank the agents based on their average AHT. The person with the lowest AHT should be ranked 1. Column is highlighed in green for your reference. Based on this ranking the work sheet named "Ranking" should be updated automatically. Since I am taking a weighted average for all agents, the one who gets the lowest AHT should be ranked 1st . In the ranking work sheet the agent with ranking 1 should be given 100, the second highest ranked person should get 98,third 96,fourth 94 etc.

Generate List Of Data Based On Sort Data From Another Worksheet

Feb 25, 2014

I have Sheet1 "MASTER" and Sheet2 "Area1" and Sheet3 "Area2" etc...

My MASTER sheet has a list of employee names and the areas they work in. I have employees working in different areas, and I want to pull a list of employee names from the MASTER working in Area1 (sorted on the MASTER sheet) to column A on Sheet2, then pull a list of employee names working in Area2 to column A on Sheet3, etc...

I want it to do this in such a way that if I add an employee to Area1 on the MASTER data, it will populate that employee in the Area1 Sheet.

So basically, I'm looking at one column on the MASTER sheet to see if the area matches. Then looking at another column on the MASTER sheet to get the name. Then taking that name and transposing it to a new sheet corresponding to the area they work in.

I've attached a sample sheet. I want Column A in the Area1 sheet to reflect all names that show up on the Area1 LIST on the MASTER sheet, and nothing else. I'm using VLOOKUP to pull the rest of the data from the MASTER table.

There is a new sample workbook up now. Couldn't update it sooner due to site outage. I've removed irrelevant data to improve readability and focus on what I'm trying to achieve. Again, the main issue is scraping column E from the Master, and populating a list of all employees who match certain values in Column E on the Master in Column A of the other tabs.
