Prevent Duplicates In Random Generations
Oct 3, 2006
How do I keep the same names from coming up on the same column when randomly generated there (I hit f9 and names randomly generate on my sheet)? I'm trying to integrate this fix into =IF(Override!G5>0, Override!G5, Shuffle!A34) formula. That formula is the formula that recieves the randomly generated names into the cells I have chosen. The override is so I can do just that if I dont like the generation of names.
example:
name 1
name 2
name 3
name 1 <---if that happens I want this cell to respond by reshuffling until it equals a name that is not in its column, but just that one cell, not the others.

I have 2 sheets, List 1 and List 2 Both lists contain generic part numbers in column A, so because there could be 2 manfacturers of the same part there will be duplication of the generic part number.
What I want is to prevent someone entering a generic part number in list 1, which already exists on list 2.
I there any cde which can be put in the sheet which will show an error message for this?

I want to set up a column of numbers that will be random without any repeating numbers.
Example: If I set up for 1,000 rows, I would like the random numbers to be 1 to 1,000, but the catch would be to have no duplicates in the column.
It has been several years since I worked with Excel and I am sure this can be done with a macro, but I am not sure how to go about it right now.

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.

I am trying to prevent/remove duplicates and blank rows from occuring in a spreadsheet which is being populated via a Userform. The user must be able to add items to the spreadsheet during the normal course of work, so I guess that the blank line removal should occur when they exit the module or application.
However, duplicate prevention is particularly important as the data being captured pertains to products. Column A of the spreadsheet contains the product code and that will be the "watch" column. I have tried various options, particularly for removing blank rows and have so far have not had success.
Something that I have noticed is that when a new item is 'added' to the spreadsheet and the job is either cancelled or not saved, that a simple resize of the range through a recount of the rows to the first one empty does not remove the blank lines which is interesting too.

The following attacted program is a name generator. It randomly generates names from the Roster sheet to the shuffle sheet (to be randomized) then displays it on the watchbill sheet. The problem I'm having is that the names seem to be repeating themselves before the entire list is used at least once from the roster sheet. I need all the names to generate at least once then have it fairly repeat the names (but not in the same columns on the watchbill sheet). Can this be done using the formulas I have? I've been trying to figure this out forever, its just a little beyond my level.

I need the easiest way to randomize or generate team numbers in a league. Using COL A assign numbers between 1 & 8 without duplicates. Then repeat 5 more times. This has to be done on the spot and has time constraints as the players will be waiting for their team assignments.
EXAMPLE: I have 48 players which will be assigned to 8 teams of 6. I want to randomize the drawing so the same players don't play on the same teams each week. Also to be able to adjust number of teams determined by how many players are present. either 6 , 8, or 10 teams.

I'm needing to generate a unique random value for a database with 3546 cases. The unique random values cannot be duplicates of each other. I tried the =RANDLOTTO function that I learned of in an old post on this board, but that results in "#NAME?" appearing in the first cell. I tried to install the Add-Ins (both the Analysis ToolPak and the Analysis ToolPak - VBA, but nothing seems to happen. Is there another way to generate these numbers?

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

I am working on a Random Cycle Count Generator that provides random SKU#s based on 3 separate columns of SKU listings. The user clicks a button to generate the SKU#s to cycle count for that day. What I would like to see is a date stamp in the columns next(B,D,F) to the referenced SKU listing(A,C,E) based on which SKU#s are generated. This will let me see the last date that the SKU was generated. I would also like it to automatically save after generating.

In short, I would like a pivot table to only count unique values, but when I click into the pivot I would like to show all instances of that value. For example:
I have a table of data that I am creating a pivot table from. There are fields for Customer ID, Task Name, Age, and Notes. There will be multiple records for a single Customer ID each time it has new notes.
I would like to create a pivot table that has Task Name in the Row Labels, Age in the Column Labels, and count of Customer ID in the Values, so that, for example, I can see how many accounts have been in the Design task for 2 days. However, when I do this it counts each record, but I would like it to count each unique Customer ID. Also, when I click into the pivot, instead of pulling up one line per Customer ID, I would like it to pull up each instance of Customer IDs in that Task Name/Age combination (similar to doing a DISTINCT in SQL).

I have a list of isometric drawing numbers ending with a [underscore]weld number e.g. 1692-SG-0040-04_05.
Some welds are repaired--in that scenario the amended weld number will be 1692-SG-0040-04_05R1, and even 1692-SG-0040-04_05R2 if repaired for a second time.
On occasion a weld may be cut out entirely and a new weld done. The weld number for that will be 6317-FG-1690-02_06C1.
And here's a wrinkle I've just verified...a cut weld may also be repaired so the weld number will look like 1698-SG-0077-01_04C1R1.
Is there a formula to count these as one weld:
1692-SG-0040-04_05
1692-SG-0040-04_05R1
1692-SG-0040-04_05R2
This as one weld:
6317-FG-1690-02_06
6317-FG-1690-02_06C1
6317-FG-1690-02_06C2
...and this as one weld:
1698-SG-0077-01_04
1698-SG-0077-01_04C1
1698-SG-0077-01_04C1R1

I am having trouble creating a function to count duplicates of duplicates.
An example of the data table 1 is:
Product 1 2nd
Product 1 2nd
Product 1 New
Product 1 New
Product 1 Flt
Product 2 2nd
Product 2 New
Product 2 New
Product 2 Flt
Product 2 Flt
Product 3 2nd
Product 3 2nd
Product 3 2nd
Product 3 New
Product 3 Flt
I created a new table (table 2) and made a list of all the Products on table 1 and removed the duplicates. I now have 3 columns with titles New, 2nd and Flt as follows:
New 2nd Flt
Product 1 XX XX XX
Product 2 XX XX XX
Product 3 XX XX XX
I am trying to count the duplicates for each product (XX), but I can't seem to work it out. I've tried the MS help function, but unsure of the actual formula I need to be using.
I am using Windows 7 and MS Office 2010.

I'm trying to Count duplicate text on sheet 2 and populate the number of times repeated on sheet 1.
On sheet 1 I have A3:A128 and would like the number of times these respective cost centers are repeated in Sheet 2 to populate Column B of Sheet 1.
File attached.
Not sure which formula to use. I tried CountIF but didn't work with 2 sheets.

When user presses "ESC" key on an open userform, data he has changed in controls (simple textbox for example) gets resetted. Right? I'm seeing such behavior in Excel 2003. How about other versions?
I'd like to see some documentation about what exactly is going on, and how to prevent such unexpected feature (that forces data loss), but could not find.
I mean that i have no commandbutton with cancel=true. By default I want to keep the data user has entered/changed. Unfortunately this data reset finds place before any trappable event, or am i wrong?
I have not found any working way to capture keypresses on userform level. Userform has _KeyPress and other events, but those are not firing? If there is one, that would be helpful. Perhaps even on system level with some APIs? Altough that sounds way too complicated for a problem that should need only one little-known flag set. Perhaps there is such property somewhere?

I made up a small subprocedure that searches through a large list of zipcodes (These zipcodes are in a separate sheet). Whenever I execute my subprocedure in another sheet, it jumps to the zipcode sheet and then goes back to where I originally executed the subprocedure.
Is there any way that I can prevent the sheets from switching back and forth?

am trying to create a workbook template which collects data from users with user forms and some macros. Users assign a project name when workbook opens and then they are able to save as the workbook with name of project name. But i don't want them to save on my template mistakenly. How do i prevent this? I tried workbook_before close sub but i can manage that it recommends to save workbook with project name and if you don't want, it still asks you if you want to save workbook before close

I've got the following code which opens/gets the excel files from a specified directory and imports them into an open workbook. I've added a GoTo Error before my loop which checks if there are any files in the directory and shows an error message if it's the case. Problem is since the loop goes on till there are no more files in the directory, it goes back to the error. How to change that ?

I have 2 workbooks open. In the workbook that I am working in I run a macro from a userform to copy a worksheet from the other workbook that is idle in the back ground. I also display another user form that says "please wait" while the macro is running.
The problem I have is even though screen updating is set to false the screen switches over to the other workbook while it is copying the desired sheet and switches back to the workbook I am copying to after the macro completes. Also the "Please Wait" userform disappears while the other workbook is displayed and reappears when the initial workbook returns.
Below is my code which works without issue but perhaps there's a better way to copy between workbooks that would prevent the screen changes?

I use a few Functions in my VBA code. All these functions, are declared as "Public", and reside in a single module. However, they are called from many different modules during code execution. (i.e. many functions called from many modules - hence the "Public" declaration).
My issue is that in addition to being available to different VBA Modules, these Functions are also available on the worksheet as a UDF (so if a user presses "=" in the formula bar, the auto-complete shows these functions when the first characters match). Is there a way to remove the availability of the function on user worksheet? i.e. to allow a Function to be called from different modules in VBA, but prevent it from being available on the worksheet.
My current work-around is to prefix all Public Function names with letter "j" - as no excel formula seems to begin with it - none of them show up as auto-complete options. Nevertheless, the Functions are still available to the user - which is what I would like to prevent.
