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)

make a calculation(addition) and use the answer to multiply against another addition calculation....
The sum of (Monday!A1:A4) multiplied by the sum of (Monday!B1:B4) plus (Tuesday!A1:A4) multiplied by the sum of (Tuesday!B1:B4) and so on.

This just a shot in the dark, but does anyone have a custom function that calculates the check digit for a cusip? http://en.wikipedia.org/wiki/CUSIP
The algorithm is listed above.

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.

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....

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.

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:

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.

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)?

I have an issue with the Data - Text to Columns operation.
I paste some data into a sheet that is comma delimeted. I have a macro that runs the Data - Text to Columns operation and then moves the data to another sheet.(The data I need to paste is coming from a non-Excel application.)
I then copy a second set of data to another sheet and when I paste it, it automatically does the Data - Text to Columns operation but I do not want it to. I have seen this several times before and when I am manually manipulating the data it isn't a problem. When I use macros to manipulate the data, I don't get the desired results because my macro includes this operation.
I have done a little testing and this issue doesn't seem to always present itself. How can I paste the data without Excel trying to out-think me and just leave the data in the comma delimeted format it is in when I paste? What causes this? Its seems like Excel is seeing similar data and "assuming" I want to perform the same operation I just performed.

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?)...........................

I have two tables excel: Table1 and Table2, as shown in the attachment below. I wish that: in Table 2 to be filled in each cell how many hours (eg. 0.166 hours) worked every train. There is an Excel function to look in Table 1, reading time intervals and automatically fill them in each cell of Table 2?

I am not too sure what this is called but I am using Excel 2010 and need particular document that I use repeatedly. Basically, if a particular cell in the document does not contain a phrase then I want Excel to automatically change the text in that cell to bold and red and 2 other cells in Excel to bold and red as well. For more information, the cell is 19–20 and K–O and the phrase in the cell is "No Inconsistency".
So if "No Inconsistency" is not found in that cell then it automatically changes the text in that cell to bold and red, and it also changes two other cells that are found in that document to bold and red as well. The coordinates of those two other cells are 19 with H–J, and the other one is 17 with H.

Using Excel 2007.
My vba code seems to be dividing a range by 1M more than 1 time
My initial value is 51543942
After by code runs the display is 0.00 MB and the value in the formula bar is 0.000000000051543942 or 5.15439E-11
I would like the final display to be 51.54 MB
what I might be doing wrong?
Code:
'Format columns
r = .Cells(Rows.Count, 1).End(xlUp).Row
Set rng = .Range("C2:C" & r)
.Range("IV1").Value = 1000000
.Range("IV1").Copy

I have a workbook that I would like the same operation on all sheets except the first sheet in the book every time I update it (which is once a week).
I get data (currency format) for all of my employees on a weekly basis. Unfortunately this data is shown as a negative number and I need to invert these values. (So I use the formula below)... but I have to do this manually for about 35 sheets and I figure I could automate this somehow with a macro. Here's what I do usually and what I would like the macro to do automatically:
I want to insert a column after column G.
I would like to enter the following formula into H2:

I am running a script that populates about 70 or so workbooks based on information from the database. Naturally this script is quite slow but what seems to take the most time is opening and closing workbooks. Is there a way to "hide" the workbook opening/closing operation on the screen? I have tried using the
Application. ScreenUpdating = False
this sped the code up but you still see the workbooks opening on the screen.

I would like to perform a sum of randomly generated numbers between 0 and 6, but I want the number of independent random numbers to be dependent on another cell. I have =SUM(RANDBETWEEN(0,6) and then I get stuck. Is there a way to perform the RANDBETWEEN(0,6) a number of times stated in another cell? In this case that value is 67 but it will vary from around 5 to 150. I think there is a way to do this with macros, but I am not versed in visual basic. I am using Excel 2003.

I wanted to have the weeks of the month down one column = 52 week.
down the next column I have different amounts of money in that week.
some months have 4 weeks and other have 5. I wanted a program to say:
If you see a month "x" look at the next column and take that amount. Then on the next row you have month "x" again (week 2) go to the next column and take that amount and add it to week one. And so on until all 4/5 week are added to give on result.
Then the same for the next month...
month amount/week amount/month
05-Mar 0
12-Mar 70
19-Mar 210
26-Mar 350 1050
02-Apr 420

I am hoping someone with excel experience can be of help to me with an unusual request for excel.
Assume cell A1 = 2, B1 = 3 and i wish the sum of this (5) to appear in cell C1. Very straight forward so far, however i wish the result to appear in C1 when i left click on a cell other than C1, say for example D7.
I can't use any macros for this.

I've got a column of numbers that represent the number of overs bowled in games of cricket. Whilst these are whole numbers (eg. 34 overs + 34 overs) the addition isn't a problem, but when they are incomplete overs (eg. 34.4 overs + 34.5 overs) then the addition if out of kilter as it sums them in base 10, and not in base 6. (As there are six balls in an over, not ten for anyone who doesn't know!)

I have multiple ranges in a spread sheet. I am trying to write a formula that will go out to each range in succession and look for a part number, upon finding return a quantity and them move on to the next range duplicating the above process. The formula should tally the grand total of all numbers found. I have it working except that not all of my items are in all ranges. If the item that I am searching for is in all ranges my formula works but if there is one or more of the ranges that doesn't have that particular value it returns an #n/a instead of totalling those that do have it. If I use a true instead of false in my [range_lookup] I get an incorrect answer. My formula for a given cell is listed below. This is with the true argument which does not work....

I am a new excel user. I a trying to write a certain formula but am having trouble. I want to write the formula to add a column of numbers, say H-10 through H-15. Each cell will have a number in it, but I want only to add the cells if the cell precedding it in the G-10 through G-15 Collumn is blank. For example if cells G-12 and G-14 have an "X" in them, then I do not want Cells H-12 and H-14 to be added. I only want the formula to add cells H-10,H-11,H-13, and H-15. I used just 6 cells for example, the column of cells to be added will be a lot longer.

I obviously know less about functions than I thought I did. I've got the attached spreadsheet set up except getting totals at the bottom. The production total L44, would be column A multiplied by the quantity entered in columns L and summed. Same for Total SF, square footage in column B times quantity in L and summed at the bottom. This would continue daily, needing sums under each column.

I wish to sum specific rows in a spreadsheet as a Grand Total. I eventually end up with a string variable called "GrandTot" that holds "=C3+C13+C25+C31+C39+C50+C53"
This formula is correct, but when I insert it into the spreadsheet it totals zero. Only when I manually write the formula does it recognize the cells it supposed to add. I am very confused as to why this is happening.
On a possibly related note, when I highlight a column in the spreadsheet, the count is including blank cells.
