VBA Code - 3 Second Cycle For Lucky Draw Random Number
Sep 20, 2012
I have the below code that i am using to generate a random number between a user defined lower limit and upper limit (these limits are set in cells "B3" and "B4" in worksheet "DRAW"), the random number that is generated displays in cell "B7" on worksheet "DRAW".
The code also allows for the draw result to be stored on a second sheet called "DRAW HISTORY", on this sheet the draw result, date and time are recorded (the date and time are stored on sheet "DRAW" in cells "C20" & "C21" and these values are pulled to the result sheet by the macro).
What i would like to happen though is instead of the random number displaying instantly i would like the numbers to cycle for 3 seconds before stopping and the result being recorded. A much better visual effect than an instant BANG here is the winner.
here is the code i am using to generate the random number and record the result:
Sub testRandom()
Dim aRow As Long
Sheets("DRAW").Range("B7") =
I was looking for some code to randomly generate a number for a prize draw I am doing. I found a great piece on this site, which I have slightly changed to give me what I have below.
It works great except for one thing I cannot work out, I have the code below working on cell "C1", I would like it to work in cell "C5", but I can't seem to work this out.
Sub SlotsNum() Dim w As Long, x As String, y As Long Randomize x = Format(Int((Range("B2") - Range("B1") + 1) * Rnd + Range("B1")), "0000") For y = 1 To 1 For w = 1 To 250 Range("C" & y) = Int(8000 * Rnd) Next w Range("C" & y) = CInt(Mid(x, y, 4)) Next y End Sub
Also, whilst here. i will have one other problem, with it being a prize draw I do not want to draw the same number twice. At the moment I have a small macro that copies the winning name that appears on the main screen (via a vlookup) onto a winners spreadsheet. I am thinking of then creating another macro that replaces the winning name on the master list with an "Already Won" entry, so we can just select again.
I'm trying to get a random prize draw working with in excel. My worksheet structure as follows.
A1 person's name B2 points obtain by the person.
A1 B2 John 10 points Ken 20 points Amy 30 points
1st draw. If random number result between 1 and 10 display John wins then delete John's entries.
2nd draw etc... and delete anyone that has already won a prize.
With the following code I found on this forum it partly works. It only randomly select a cell but missing displaying the winner and removing it afterwards.
I am trying to get a sheet to automatically calculate week numbers from a given date (start) and the current date, the problem I am having is I only want to cycle 18 weeks not 52.so weeknum wont work
ie 10 weeks after start date would return Week 10 18 weeks after start date would return Week 18 19 weeks after start date would return Week 1 25 weeks after star date would return Week 6 37 weeks after start date would return Week 1 etc...
I'm working on a spreadsheet to compile and print checks. All the check information except the date and first check number is contained in a Wins sheet. I also have a Checks sheet which contains a master check. I used text boxes on the master check to contain individual check information. Each text box is filled in from the Wins sheet by means of formulas. The problem I'm having is how to modify the formula entries in the following code to cycle or loop through all checks required. A sample spreadsheet is attached.
I have a list of 10 of my favorite/lucky numbers that I want to play in the lottery. The lottery picks 5 numbers total. I need a way to show me all the possible combinations of my 10 numbers picked in a 5 number draw (hope that makes sense). There are no repeat combinations- for example- I DO NOT WANT 1-2-3-4-5 and 5-4-3-2-1 to come up as separate combinations- so each of my favorite #s needs to be used only once in each combination, and each set used once.
I have searched this board for 2 hours now- read tons of other posts, but not finding a real solution. The output will be a list of all the possible combinations (no repeats, and no permutations) using my 10 favorite numbers. Another example- 1-2-3-4-5 1-2-3-4-6 1-2-3-4-7 1-2-3-4-8 1-2-3-4-9 1-2-3-5-6 1-2-3-5-7 and so on.
How do I create this? I realize the resulting table will be quite a large number of combinations- but we're going to have fun with it and pick a few at random.
There is definite problem, as the "Code execution has been interrupted" error message appears seemingly at random (although if the workbook doesnt change it is the same points), and for no reason.
If I click the continue button the macro runs exactly as planned, but still there seems to be no rhyme or reason as to why this happens!
How do I make a row of 5 random numbers in A2:A6 that are not the same as each other. It's basically for a Bingo card. I have a formula that can calculate the random numbers =INT(RAND()*15)+1 under the B's for example, but I can't seem to figure out how to make it so they are not the same.
I want to create a simple worksheet that takes a list of names (All of the members of my family) and Randomly selects another name from that same list and matches them to it ( I don't want to say "paired" because I want each person to have a one way relationship to the other, in other words just because personA is matched to personB, i don't want personB to automatically be paired to personA) I hope that makes sense. Once every name on the list is matched with a person I would like to move that name to a database that I can track each year. The practical application of it is this: Each year our family randomly draws names and we are tasked to buy a new x-mas ornimate for that person, ideally you would not get the same person 2 years in a row, and the person that you have does not have you in return simply to add more variety and the database would track who had who each year.
Code: Sub test() Dim a, i As Long, temp, n As Long a = Range("b2", Range("b" & Rows.Count).End(xlUp)) Randomize With CreateObject("System.Collections.SortedList") For i = 1 To UBound(a, 1)
This would generate a random number into RPlayerNum variable, based on the list in sheet RPlay, missing off row 1 as the header.
However we have noticed a massive flaw in this code.... It works as long as the excel file is open, each time run it gives a different random number. However if you close the excel file and open it, then run it, it ALWAYS gives the same number first run, every time.
If I generate a random number in cell A1 ranging from 1 to 3. Can I count how many times the result is equal to 2 if I was to run it 100 times and then show the results in cell A3.
I need a macro that will select a random number between 1 and 6. ie select the number of a dice. It needs to input 1 random value into one cell and another random value into another. Like the dice values of a monopoly game.
is if there is a way to generate random numbers between 0001 and 9999. I always need to always have 4 digits. The first couple of numbers can be 0 so that I can maximize the number of variations.
I get the following error whenever I try running a Monte Carlo simulation with iterations in excess of 64000 (The MC simulation calls the 'NormSInv' worksheet function at least once per iteration, and the argument to the 'NormSInv' function is always a standard normal RANDOM number also generated by Excel VBA): Run-time error '1004': Unable to get the NormSInv property of the WorksheetFunction class Why do I inevitably encounter this error ONLY when the number of iterations exceeds 64000, for instance? Simulations with iterations < 64000 run smoothly without a glitch.
I am using the data analysis add-in to generate a random number (using the random number generation) using a normal distribution. The problem is, i want it to recalculate these numbers every time the worksheet is recalculated but the numbers seem to be values only.
i have worked in access using vba procedures. i can easily create a form in access that generates a random integer number between 0 and 20 and the user will guess the number between 1 to 20 if the random number is 16 and the user enters 14 the program will display a msg box saying too low or too high. here is the code .
Option Explicit Private Const MAX = 20 Private Const MIN = 1 Private iKey As Integer Private lTries As Long
Private Function Random() As Integer Random = CInt(Int((MAX - MIN + 1) * Rnd() + MIN)) End Function
Private Sub cmdGuess_Click() Dim lGuess As Long
now i have to do the same thing in excel create a program that will ask the user to enter numbers between 0 to 20 and see if the random number and user guess is same or not. but i have never worked in excel using vba procedures how can i achieve the same thing in excel using a vba procedures.
I have a random number generater but it creates a new random number whenever I recalculate the sheet or enter something in another cell. I would like it to choose a random number once and not do it again until a condition, specificaly a date, is met.
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 two worksheets. ws1 contains a large number of dates on column 3. ws3 contains around 20 dates on column 3.
I want to pick two dates randomly in ws1 that does not already exist in ws3.
Here is my working code, but it is really slow to process. How to optimize this code? Also I would like to add a function where if the macro is not able to find two random dates that aren't already in ws3 then exit loop.
VB: Set ws1 = thisworkbook.sheets(1) Set ws3 = thisworkbook.sheets(3)
lr = ws2.Cells.Find(What:="*", After:=[A1], SearchDirection:=xlPrevious).Row Set rvis = ws2.Range("c2:c" & lr).SpecialCells(xlCellTypeVisible) mynodate = 0
is there any rule for random number to be picked up? Any Rule, Any Formulae, Any Calculation Anything, Any authentic routine which may guess what would be the next random number? for example if first random number is 825587 then what would be the next?
I understand how RAND and RANDBETWEEN work, but have a slightly more complicated random number generation problem that requires a number that isn't solely between two numbers.
I have one cell that is randomly generating a number between 0 and 350 (we'll call this value A) and another randomly generating a number between 0 and 15 (value B). Then, I have a third cell (value C) that equals 15 minus B. Where I am having trouble is with a fourth cell (value D). This cell I want to have randomly generate a number between 0 and 350 but it needs to be D less than the value in A or C more than the value in A. Is there an advanced random number generation technique that can solve this?
I have a spreadsheet of 1000+ companies and I want to take a random sampling of 100 of them. I would assume this could be accomplished by auto-filling a numerical value to each line of data (which I did), then scrambling only the column with the numbers (which I can't figure out), and then selecting the entire text and resorting it to put the numbers back in order and then just work with the first 100 rows (which I can do, if I knew how to make the numbers random).
