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.

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.

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).

I have 4 names, and a grid of 100 boxes. I need those 4 names randomly deposited in the 100 boxes, making sure each name is displayed an equal number of times (25 each) Is there an Excel formula to compute this?

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.

Private Sub CommandButton1_Click() Dim x As String, i As Byte Randomize x = Format$(Int(Rnd * 1899) + 1, "0000") For i = 1 To Len(x) Me.Controls("TextBox" & i).Value = Mid$(x, i, 1) Next End Sub

I have code that generates random numbers 1 - 90, what I would like is when the command button is pressed the numbers are generated every 5 seconds, I have attached the workbook.

I have a set of data with index numbers and the percentage of their occurrence. I want to use this percentage to weight the occurrence of the index numbers and create a random list of say 500 occurrences.

how to go about generating random numbers based on Weibull distribution in VBA? I had a rough idea for Normal (from link below) which i later extended to Lognormal but am having difficulty with Weibull and Gamma will appreciate any help.

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 6 7

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.

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.

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.

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.

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)))..............

I need a formula that can randomly pick a persons dependent on the amount of entries they have in a competition. For Example

PersonEntries Andrew10 Jake15 Louisa4 Fuffy33

In the above case there is 62 entries into the draw. Andrew has 10 chances to win. Is there a formula that I can use that will decide a winner for me dependent on how many chances they have.

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

i want is a way, on clicking a button on my userform, where i can bring up a quote randomly picked from a list of quotes and sayings which I will input.

I know you can make a random number generator pretty easily in excel...but is it possible to make a random word generator? I will give the words I want randomly generated.

I have a database of at least 350 products, and would like to know how I can use a form button, when clicked it will randomly display a picture of one of the list of products. I want to use this method for a mystery prize draw.
