I want to create a VBA function that can calculate the CRC32 checksum for a file.
I found this webpage which looks promising: http:[url].....
The only catch is that the code provided is VB not VBA. How hard would it be to tweak this code to run in VBA?
I have around 300 7 digit numbers prefixed with a letter. Two examples X4032818 G8007700 The letter is a form of checksum to check if the numbers are correct. I have tried a number of Chksum algorithms but stuck on this one. The letters I and O are not used leaving 24 letters. I have used MOD with a divisor of 24 and compared it with a table, 0=A thru to 23=Z

I suspect there is some kind of checksum built into the cardnr. Any tips on how to check for the validity would be appreciated, including links to relevant sites.

What I'm trying too do is open a file, make an exact copy and save it under a new file name.
My problem is in the date formula the day is not always the same. In the sample case it's 03 at other times the day will change.
is there a way too get this too work irregardles of what the day might be?
I have a base excel file for summarizing some data, the problem is that the data comes from a different excel spreadsheet. What I want to do is make a function that pulls the data from another spreadsheet into my base file. It would be easy if it were just one excel sheet, but this job would require where the data is pulled from a data file which has many modified versions.
Can anyone tell me how to do this? The files with the data will be structured the exact same but with different data entered in. I just want a button so I can click the file I want the data from and have it show up on my summarizing base file.
Formula which can calculate how many days in a month and create a column for each day. Columns for day 28, 29, 30 or 31 also need the formulas in columns 1 to 27 copied over automatically. [sheet name "LARSheet1 to 1" ]
I'm trying to build "Leave, Attendance Management" system using Excel. I am about 40% there so far.
The basic structure of the workbook is as follows:
12x main monthly "Leave Attendance Record" worksheets (i.emonths April 2012 through to March 2013). [I will refer to these sheets asLARSheet1 to LARSheet12 ].
1 x worksheet which holds "data validation" list andvlook up info. ["FormulaListSheet"]
1 x worksheet acting as a database of staff details andpay numbers. ["StaffdBaseSheet"]
1 x summary page which shows staff reaming leaveallocation. ["SummaryLeaveSheet"]
What I'm having problems with at the moment is as follows:
A formula or a macro which works out how many days are present in a given month [starting date of month located in CELL B10].
Days 1-27 will be already set up on the sheet. Based upon the monthly value I would like a solution which can calculate how many days are in a month and create a column for days 28, 29, 30 or 31 (depending on the month).
I would like it to work like this:
When the user opens a new worksheet, they first entre the month start date in CELL B10. Hopefully this will trigger columns E13:AH22 to update with the relevant week day & date.
I also need the formulas and formatting in cells AH13:AH100 (column for day 27) to copied over automatically.

I need to do the following and can't figure it out. How do I create a running average that will only calculate the averages in % each month. Example: Opt 1 for Jan, Feb, Mar =1 each= 3 total = 100%; OPt 2 for Jan, Feb, Mar =1,0,1= 2 = 66%; Opt 3 for Jan, Feb, Mar = 0, 0, 1 = 1 total = 33%. My problems is I want monthly running average that shows the yearly percentage up to date but only for the months there is a value 1 or 0. How can this be done because the way I have it now, those % are being divided by 12 and that isn't the correct %

I am trying to create a spreadsheet to calculate the macro nutrient ratio of foods based on carbohydrates, proteins, and fats and how many units/servings I eat of each. I've attached the file I've started. It's fairly straightforward and simple, thus far.
I would like to be able to associate a food with its various nutritional data in its row (fat, carbs, sugar, fiber, sat. fats, protein.. etc.). With all of my food items entered, I would like to be able to choose from a list, have it prompt me for how many units I've eaten then plug it into my formula to calculate totals and ratios.. The final flow should go soemthing like this...
1. Select a food from a list (each food on the list has its associated characteristics)..
2. Select how much ( each food will have an associated serving size i.e. 1/2 cup, 1oz..) ---- (4) oz VS. entering each unit in A1
3. Make these totals of each characteristic feed into my final chart with which to track and graph.
I have a workbook that calculates a RAND function based on input in another cell. Specifically, the formula in E2 selects a random text string from another range depending on data entered in D2. I want to be able to fill this formula down for use multiple times.
The formula works fine on its own, but the problem comes when I, say, move on to D3 to input more data. E3 does its random calculation as it should, but E2 also recalculates; I want E2 to remain static once it calculates the first time.
I'm attaching the workbook in question. The calculation I'm referring to is in the 3rd worksheet.

I have a spreadsheet that keeps attendance. Now I need to calculate the
units (1 unit= 15 minutes) the children are actual here. On a normal
schedule they are here for 16 units but if the are late the units get
subtracted. When entering the data, they would like to use letter instead of
numbers.
I am trying to calculate payroll. I have 2 columns where regular hours and overtime hours are manually inputed. They are then multiplied by their respective pay per hour columns to come up with regular and overtime pay. The next column adds these to get total gross pay. That gross pay is then multiplied by the FICA and FICA Med factors to figure those taxes(2 different columns). I then have a column the adds all deductions to get total deductions(Fed,FICA,FICAMed,St). The last column subtracts total deductions from the gross pay column to get net income. My problem is the net pay column is $.01 off sometimes.
I think what is happening is I obviously have all columns in dollar amounts with 2 decimal points. Some function columns have multiple decimal points in the answer and then are only showing the 2 decimal points. When those columns are used in the next equation, instead of using the dollar amount that is showing with 2 decimal points, it is remembering the multiple decimal points. This is resulting in being a penny off when I get to the end. How can I get the equations to use what actually shows in the columns(2 decimal points) instead of remembering multiple decimal places?
I have written the code below. But it didn't work. In my opinion the error is most probably caused by irr worksheet function. Because the code is actually bigger and I tried it all part by part.

create a macro that will find and calculate based on the details of 4 columns on the same spreadsheet.
Basically, here is what I need to do:
1. Need to calculate how many QTY IN (Column F) and PALLETS IN (Column I) of a specific PART# (Column A) and LOT CODE (Column B) For example if enter a PART # and LOT CODE, it will calculate how many QTY IN and PALLET IN of that PART # and LOT CODE.
2. Need to do the same for QTY OUT (Column G) and PALLETS OUT (Column J) also.
3. Output should contain the PALLET # , QTY IN and PALLETS IN based on the PART # and LOT CODE search. I just want to simplify the search function in this spreadsheet because it is very cumbersome if you need to find how many items left for that PART # and LOT CODE.
Attached is the spreadsheet..
I am making an excel sheet which can track the hypothetical effect building an order has on current inventory. The user is to change the quantities in this hypothetical order whenever they want.
It is composed of two sheets, the inventory sheet and the model sheet. The inventory sheet has the costs of every part carried and how many are currently in stock. The model sheet has a breakdown of what parts are required to build the different models.
I am looking for a function or VBA which can take a hypothetical order (build xx of model one + build xx of model two + build xx of model three), see how many total parts are needed, then calculate and display the effect it has on current inventory. This is only to see the hypothetical effect on inventory, not to actually change the inventory in the inventory sheet.
I've attached what I have so far - most everything is completed except for this final calculation. I have tried using the VLOOKUP function in VBA to try and come up with a solution but I couldn't figure out the best way to go about this. I think the hardest part might be that a hypothetical order can be made up of all three models.
I'm trying to calculate the mode for a large data set, but there is no 'mode function' in subtotal. I need to find the mode for each change in day - without having to retype the function.
View 11 Replies View RelatedI'm writing a spreadsheet where I need to calculate a nested IF function (I think), and I am unsure of how to do it.
The problem is this:
The total $ value of the quote is entered, then depending on two variables, a rebate may be deducted from this total value. The first variable is eligibility (a Y/N response), the second is the type of project - there are two types of project and each attract a different rebate amount.
So I have:
A: total quote $
B: Eligibility - 'Y' or 'N' (if 'Y', then value of 'C' is deducted from 'A'), (if 'N', then no value is deducted from 'A')
C: Type - '1' or '2' (if '1', then 'C' = $1000), (if '2', then 'C' = $1600)
D: final result
I'm struggling with the VBA DATEDIFF function. I have a person's DOB and am attempting to determine their age by comparing to a different date. It seems like their age only changes when I change the year, rather than choose a date within the year past their birth date... Here is my code:
Sub Test_click()
DOB1 = #7/19/1930# 'DOB
date2 = #7/18/2012#
Date3 = #7/21/2012#
age1 = DateDiff("yyyy", DOB1, date2) 'age should be 81 (but is 82)
age2 = DateDiff("yyyy", DOB1, date2) 'age is 82 (correct)

I have just built a spreadsheet to calculate training hours amongst other things. I have used the function NETWORKDAYS which calculates the number of working days between two dates. This works fine on my laptop which has the analysis tools pack installed. Unfortunately my work place IS policy wont allow the analysis pack to be installed so need to find away around this. Does anyone know a formula that will perform the same function as the NETWORKDAYS. THis is crucial to the accurate calculation of training hours.
I have a dataset of students' grades (see sample below) which I need to compute the aggregates for.
Blanks indicate that the student did not take the subject. Aggregate is computed based on 6 relevant subjects, lowest is best.
Rules for computing aggregates:
1st subject: EL or HMT
2nd subject: H1 or H2
3rd subject: M1, M2, S1 or S2
4th subject: H1, H2, M1, M2, S1 or S2 (but not previously used)
5th & 6th subjects: Any other 2 not previously used

I currently have in my equation the trend function to linear extrapolate the date a line would cross either my upper or lower limits (100.1 and 19.9) between 2 data points. However if the 2 data points span both the upper and lower limits (as per the 2 attached examples) then unfortunately the trend function is only able to return the 1 date (where I've specified the x value). Is there any way for the TREND function to trend the 2 values? Do I simply add the 2nd x value to the new x's?

What would the formula be to calculate that array of values = 57% because 4 of them are equal to or greater than 9, and there are 7 of them in total? The formula should accommodate however many numbers are listed and calculate what percentage of them are 9 or 10.
I am using a formula to calculate the last day of the month, using any date of the month in a worksheet in cell A13, this cell is also linked to another worksheet to pick up a date, using the ISBLANK function to prevent a dummy date entry appearing if the field in the linked ASHBY RISE worksheet is blank
=IF(ISBLANK('ASHBY RISE'!$C$5),"",'ASHBY RISE'!$C$5)
The last day of the month function is shown below
=DATE(YEAR(A13),MONTH(A13)+1,0)
This works fine if there is a date in A13, but returns a #VALUE! error if cell A13 is blank. I have tried using the ISBLANK function, but I am still getting the #VALUE! error. Of course I may have the sysntax incorrect.
I want to obtain from some elements the number of cells it takes to appear:
We have for example A,B,C, and D,
and they appear in the next order:
1A
2C
3D
4A
5D
6B
7C
8A
9A
What I want to know is how much last in appear each element.
1A1
2C2
3D3
4A3
5D2
6B6
7C5
8A4
9A1
For example, the first “A” last one in appear, but the next element “C” last two in appear. In the forth line again cames the “A”, then are three cells. The “C” was in the cell2, and cames again in the seventh cell, then it takes five cells. In the cells eight and nine are two “A”, then in the cell nine takes one cell in appear again.
As everyone realizes that WORKDAY function can return a working date that exclude weekends and any dates identified as holidays. However, what if I want to return a working date excluding my designated holidays but including weekends?
For example,
Holidays are 1 Jun 2009, 2 Jun 2009 and 4 Jun 2009
Start Date: ???
Finish Date: 8 Jun 2009
Duration: 5 days
The Start Date should be 30 May 2009.
Seems like I am not able to use WORKDAY function to calculate the start date.
