How Do I Use VBA Timer Subroutines To Start And Stop Random Number Generator

Oct 6, 2008

As you can see below, I've written code that writes random numbers into three columns of a spreadsheet (10 numbers in each column).

What I want to do is create code that will run the random number generator for a period of 1 minute and then stop. I know that I will need to write a timer subroutine to do this but I'm how unsure how to do this.

Start/Stop Timer For Hours Worked To Include Break Time

Oct 15, 2007

I have a timesheet where user updates start and end time for various tasks.

I have placed a time capture button in the excel sheet (which is simply a macro saying =now() function)

The user clicks it before starting and after finishing the task. The start and end times are captured in adjacent cells.

If the user starts the work, and goes on a lunch break say for 20 min, comes back finishes the task and captures end time, the time difference will not consider break time which is non productive.

How can I incorporate something like 'pause' option so that before he goes for lunch he can temporarily pause the time.

Random Number Generator From 1 To 7 Other Than Cell Value

May 12, 2007

I have a range of cells that have values from 1 to 7 in them. What I would like to do is to have the next column generate a random number from 1 to 7 that does not generate the number that the cell next to it has. for example if cell A1 has 6 in it, I would like cell b1 to generate a random number other than 6 in it. if cell A2 has 3 in it then cell B2 would generate a number other that 3 (1,2,4,5,6, and 7).

Random Number Generator Macro

Feb 27, 2007

What I'm trying to do is as follows:

Sheet 1
A1 through A6 has STR, DEX, CON, INT, WIS and CHA. B1 through B6 is waiting for results from sheet 2.

Sheet 2
A1 is data validation of d4, d6, d8, d10, d12, d20 and d100. A2 through A7 are currently Rand formulae triggered by A1 with B1 adding number of dice (minimum 1) and B2 a modifier value add to the rolled result. D2 through D7 are data validation modifiers of -10 to +10 (0 included). E2 through E7 is the result of A2+C2. The Rand works fine, but every time data is changed Rand recalculates. I'm hoping for a macro executed by a button to generate six random numbers based on the chosen die value of A1 ranging from 1-4 to 1-100. The die roll can never be below 1 and no higher than the chosen die. I then want to transfer the result from E? To sheet 1 B1 to B6 matching its appropriate atribute. I named them Char01_STR, etc on sheet 1 A1 to A6.

Fill Number Series Based On Start / Stop Of 2 Cells

Jan 18, 2008

I have a excel sheet of data numbers which blongs a packet of inventory where i found number series like this:

Start Range End Range Qty
2101200 2101499 300

I have to draw this onto a series like 2101200 then 2101201 then 2010202 etc.
but some time these numbers are in qty 30000 or more. I have questions

1- If any macro colud fill series suppose if write number in A2 and qty in B2 so it reads the qty of b2 and fill the series in A. If i write 1 in A2 and write 50 in B2 so the series should be auto fill 1 to 50.

My Second question is opposit of my above question.

2- if i have different number series in column a and i want them to be as start number in column b and end number in column c and qty in column d based like mentioned below example.
Series [b]Start Range End Range Qty
1 1 1 1
3 3 3 1
5 5 7 3

Random Team Generator?

Jul 11, 2013

I am organizing a sports tournament and would like excel to randomly generate the teams for it.

We have 20 people who will be organized into 10 teams of two. how to setup the formula to have two people randomly paired together without duplication. The names will be further used in other formulas for points calculations.

So, I have the names as A1:A20 and then would like the teams generated from B1:B10 and C1:C10 with the team being the row and the team members in the B and C columns.

Create Random Name Generator?

I am trying to create a random name generator. I have tried something like this...

=INDEX('TM Names'!$A$2:$A$36,INT(RAND()*35+1))

But sometimes it will give you the same name 2 or 3 times in a row. I need it to pull up a different name each time, from a list of names I already have.

Random Generator With No Duplicates

Apr 18, 2013

In Column A I have a list of 8 team names.

In column AB I have a list of 28 weeks written in date format.

In column B I'd like to chose one week from the 28 weeks listed in AB at random. But B2 - B9 can not have the same date (ie could not have two dates for the 19th of April).

How exactly is that done?

Alternatively - is it possible to have in Column AA the 8 team names. In Column AB the 28 weeks. In Column A a random team picked from column AA and in Column B a random date picked from Column AB. Both column A and Column B can not have duplicates... There's 28 weeks with 8 teams - therefore I only need 8 unique weeks.

Random Word Generator

Aug 22, 2007

Has anyone seen an Excel program that will generate words based on letters entered. For example, if I had 10 cells in a row, and each cell contained a letter (duplicates are okay), what words could be derived from arranging those letters in random sequences.

It would need the ability to accept any letter of the alphabet, A thru Z

E A L R C T S S U C
___ ___ ___ ___ ___ ___ ___ ___ ___ ___

How many words could it generate, and what are the words?
I assume it would have to reference a spelling dictionary.

It could be used as a spelling learning game, etc.

Then if I need to want that list to only randomize B2 to thru B28

And so forth.

Sort of being able to pick from a pop up message box or userform that will ask you how many names to randomize in that list.

Random Password Generator

Jul 2, 2008

I wrote this to help me generate a random password for a workbook. I am happy with it so far, but I was wondering if there is a way, to shuffle the order of the variables? So, instead of MyPassword always being A, B, C, D, E etc

Sub RandPass()
Dim A As String, B As String, C As String
Dim D As String, E As String, F As String
Dim H As String, I As String, J As String
Dim K As String, L As String, M As String
Dim MyPassword As String
Dim v

ReDim v(33 To 47) As Variant
A = Chr(Int((UBound(v) - LBound(v) + 1) * Rnd + LBound(v)))..............

Random Generator With Several Outputs

Feb 14, 2007

I need a formula to create random letters down a column: A-F. Probability of A=3%, B=6%, C=8%, D=11%, E=14%, F=16%. I've got it worked out to where each letter is a header of a column ("A" is in A1, "B" is in B1, etc.). My question is: how do I consolidate that in one column, so that, "A" for example, reads ABFCBACFBFBECEABCEABCEAFBCEFBCAFEBCFAEBFC...? I'm using the random number generator for the 6 columns...thx
