Code To Check For Duplicates In Column
Jun 10, 2014
Obviously there is the Remove Duplicates option but I want something a bit different plus this option won't be available as the workbook is on complete lockdown.
There will always only be 214 rows to check in column B and the data cannot be sorted or it will mess a lot of things up!
Just wondering if there's some code that can check for duplicate entries because for the workbook to work, each row must have a different entry.
When the user selects this sheet a message box pops up telling them they can't have two or more entries the same but I feel this isn't enough as there's nothing actually stopping them doing this.

I have created a userform that inputs employees names in to a sheet called employee list. It works well, now I want to take it a stage further and check to see if the employee being entered is already in the list and if so let the end user decide whether enter the new data or save the data already in the list.
Private Sub cmdOK_Click()
ActiveWorkbook.Sheets("Employee List").Activate
Range("A1").Select
Do
If IsEmpty(ActiveCell) = False Then
ActiveCell.Offset(1, 0).Select
End If
Loop Until IsEmpty(ActiveCell) = True
ActiveCell.Value = txtName.Value
ActiveCell.Offset(0, 1) = txtLast.Value
ActiveCell.Offset(0, 2) = TxtNum.Value
ActiveCell.Offset(0, 3) = cboCourse.Value
If optIntroduction = True Then
ActiveCell.Offset(0, 4).Value = "Operative"
ElseIf optIntermediate = True Then
ActiveCell.Offset(0, 4).Value = "Team Leader"
Else
ActiveCell.Offset(0, 4).Value = "Manager"
End If
Range("A1").Select
End Sub

I have 3 columns A,B and C and at the end of each column i have the row with total values of A, B and C. So I need to make sure that only one value is posted in one of the 3 column values and also if in the current row if the values are properly entered( that is only one of the 3 values is entered) then insert a blank line just before the Total row. I have this code to insert the new row which is working fine. but i need to validate before i could run the code. that is i need to make sure in the selected row, only one value is entered. Note: I want to validate only for the rows that has the cursor present in it.

I have a distribution list which has names in columns G, H & I (titles in row 2 & 3) data starting row 4. A persons name may appear in any of the 3 columns and may appear only once or many times in the same or multiple columns BUT should not happen in the same row, (rows are cost centres while the columns are types so a person can only get one type per cost centre).
What I need is a formula that will check that there are no duplicate names on a row in columns G:I.
If there were duplicates, is there a formula that would tell me where it is?
The formula could return a result in say G1 which I could format using Conditional Formatting, or would a routine be better for this?
The data could be moved down if more space is needed above the title rows or a separate sheet could be used as a check and query sheet.

I have a workbook where there are around 10 worksheets. All of them are build the same, but only different sheet name (country name)
What I would like to do is use the column A to check if no one did put a duplicate in a differnt sheet. Now I have a formula in each sheet, but it would be great if it would also look in the rest of the sheets if there is no duplicate.

I have a simple spread sheet, as shown below. Each line is on it's own row, and all the info on each line is in the first cell. (A1,A2,A3 etc....) What I require is a macro that will look at the "Code" line, take note of the code and if it finds a duplicate code number, mark the duplicate code with (1)....say up to (5).
In the case below, it would flag the second 07edr code and change it to 07edr(1). If there was a third 07edr code it would mark it 07edr(2) etc.
It needs to look at all the codes as it's possible there will be more then one set of duplicates.
Description = item 1
Code = 07edr
Quantity = 1
Description = item 3
Code = 08geo
Quantity = 2
Description = item 78
Code = 08cpm
Quantity = 1
Description = item 1
Code = 07edr
Quantity = 2
Description = item 39
Code = 16blf
Quantity = 1

I am trying to improve my expense report template and need to check on the load if expense report number has been loaded correctly as well as if this report has been previously loaded. Expense report number format looks like this: AAA-BBBBBB-CC
Where:
AAA – Employee ID #
BBBBBB – End of the week date
CC – Weekly expense report number
For instance, 023-122008-01 means: Employee number 023, week ending date 12/20/2008, weekly expense report number 01. I would like to prevent/give warning of loading incorrect expense report number format, check for possible duplicates, and check if trying to load expense report belongs to the right person (by simply matching previously loaded in different cell of the same sheet employee ID and first three digits of just loaded expense report number. I think I know how to do all of these separate, but have no idea how to combine all three checks for one cell.

I currently have the code below, and it checks if there are duplicates of the entered value on all sheets. I would also like to prevent users from entering a value that is not within a certain range. How to add this to my code? I've tried to add another If, but it just ended up looping.
Maybe it would be good to make something like:
1. first check if value is within range (between 1000000 and 3999999). if not within range: msgbox and delete entry.
2. then check for duplicates
Here is the code I have so far:

I’m looking for a code that finds all duplicate words in column A & B and change the font of the found duplicate word in column B to ColorIndex = 11 and .FontStyle = “Bold”
I need this code to run frequently and possibly we can combine it with http://www.mrexcel.com/board2/viewto...272792#1272792
The wb is a dictionary and as I’m adding new words in new rows the wb needs to update. It is of course mostly important it updates when I open the wb, but it would be interesting if it could update for every new row (word) added as I might not want to close and re-open the wb just for this.

I have a table that looks like this:

I would like to obtain a table in the following format where I can find
ID HostLocation NDaysinHost
marina.silva USA, Norway, Bolivia, Italy, Ecuador... 100,45,67,8,9...
tatiana.gottig Venezuela, Chile, Peru, Canada 89,54,32,6
Searching in the net I found the following code:
VB:
Sub groupConcat()Dim dc As Object
Dim inputArray As Variant
Dim i As Integer
Set dc = CreateObject("Scripting.Dictionary")
inputArray = WorksheetFunction.Transpose(Sheets(1).Range("A2:C9").Value)
[Code]....
However I only obtain the first two columns concatenated. It says that for more columns repeat the loop, however I did and the result was not the expected, it returned me the same two columns again concatenated. How can I arrange this to fit my criteria?

I have a set of text in rows which includes duplicates like this:
Column A
Text 1
Text2
Text1
Text500
Text500
I then need to remove the duplicates and put them in column B. I normally use the remove duplicates button in Excel to do this but seeing as I have to do this task every day, I was hoping there would be either a formula or VBA solution which automatically does this?

I love this forum, and am usually able to find the help I need without bothering anyone However this one has me stumped and I wonder if anyone can help. It feels like it should be a fairly simple solution, but they can often be the ones that are most eluding LOL!
I have two columns; in column A are incoming telephone numbers and in column B are the date and time the calls were made. (I've put a few hashes in column A just to maintain confidentiality of the numbers, but in reality the cell is formatted as text in order to maintain the leading zero, and entries will follow the format 01234567890)
A sample would look like this:
0##6270####01-Mar-2009 00:01:440##6271####01-Mar-2009 00:03:020##6271####01-Mar-2009 00:03:040##6272####01-Mar-2009 00:16:330##6273####01-Mar-2009 00:30:490##6274####01-Mar-2009 00:55:470##6274####01-Mar-2009 01:06:170##6274####01-Mar-2009 01:07:420##6275####01-Mar-2009 01:08:360##6275####01-Mar-2009 01:11:410##6276####01-Mar-2009 01:13:45
Some numbers only call in once, I need to identify them as only called once.
Some numbers call twice, if they do I need to be able to show time it took between call 1 and call 2.
Some numbers call more than twice. For each successive call I need to be able to show the time since the previous call.
In my mind, the results table would need to look something like this:
NumberTime of callTime between
1st and 2nd call
Time between
2nd and 3rd call
Time between
3rd and 4th call
0##6270####01-Mar-2009 00:01:44Only called once0##6271####01-Mar-2009 00:03:0200:00:020##6272####01-Mar-2009 00:16:33Only called once0##6273####01-Mar-2009 00:30:49Only called once0##6274####01-Mar-2009 00:55:4700:10:3000:01:250##6275####01-Mar-2009 01:08:3600:03:050##6276####01-Mar-2009 01:13:45Only called once

I need to remove the duplicates under column B for each item under column A and I can't seem to figure out how to do it.
I'm using Excel 2007; I would prefer a VBA solution, as I have to do this on a monthly basis. However, if a formula is the best way to go, then that's just fine. Either way, I'm preparing the data for a pivot table. I am unable to post the actual document in the interest of data protection.
Essentially, I'd like to turn this-
_ A B
1 Paris Bill
2 Paris Bill
3 Paris Mike
4 Paris Derek
5 Paris Derek
6 London Mike
7 London Bill
8 London Mike
9 London Bill
10 London Derek
11 Tokyo Derek
12 Tokyo Derek
13 Tokyo Derek
into this-
_ A B
1 Paris Bill
2 Paris Mike
3 Paris Derek
4 London Mike
5 London Bill
6 London Derek
7 Tokyo Derek
In other words, each city should have only one instance of any name that accompanies it; not all names will accompany each city.

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

For example a17 a50000 the user will enter the date of the order. and in column B has the order number. I want the formula to count the order numbers for a data range in column A.
Here is what I have but it is counting the dates in col A not the order numbers in B?

I use a userform to make sales data entries into a database. The userform contains textboxes for:
Invoice No.Invoice DateGrossVatNet The Invoice No. is the first entry box on the userform and it is important that users enter the correct format (which is alphanumeric).
It is also important that a checking is carried out to ensure that the Invoice Number being entered has not already been used.
I use the following code to ensure that the numbers are entered in the desired format:
Code:
Private Sub txtInv_Exit(ByVal Cancel As MSForms.ReturnBoolean)
If txtInv.Value = vbNullString Then Exit Sub
If (Not UCase(Me.txtInv.Value) Like "ST###") And (Not UCase(Me.txtInv.Value) Like "ST####") Then
MsgBox "Non Valid Invoice Number.â€
Cancel = True
End If
End Sub
And this code is pasted lower down the VB editor window. And it seems to be working fine!
For the checking to ensure that the invoice number being typed into the textbox has not already been used, I use the following two codes combined together:
a) to check for invoice No.:
Code:
check for Invoice Number
If Trim(Me.txtInv.Value) = "" Then
Me.txtInv.SetFocus
MsgBox "Please Enter Invoice No."
Exit Sub
End If
b) And to it I add the following additional code for CHECKING that the no. does not already exist in the database (the invoice nos are located in Column A of the database):
Code:
Dim x
X= Application.Match(Me.txtInv.Value, Columns(1),0)
If Not IsError(x) Then
MsgBox Me.txtInv.Value & "Invoice Number Is Already Used"
Me.txtInv.SetFocus
Cancel = True
Exit Sub
End If
My problem with the second set of codes in (a) & (b) (for the Checking of already existing No.) is that the code allows the user to key in the Invoice No. and go through filling in the other textboxes. It is only after clicking the ‘Add’ button that a msgbox comes up to indicate that the ‘invoice no. is already used’.
I need a tweaking of the codes so that the moment an invoice no. that has already been used is typed into the textbox and the TAB button pressed, a msgbox will show up at that stage to indicate that the ‘Invoice no. is already used’. This will reduce time and avoid filling in the other textboxes and clicking the ‘Add’ button before the checking is done.

I have some code that will Kill a DB if it already exists, but I want to check if it exists and warn the user before this happens.
I am not that familiar with ADO, so I was fumbling through the Help topics trying to learn about ADO type names, etc. b/c i thought I could use something like:
If TypeName(MyDB) = "ADODB" Then . . .
but even if that ran, the argument in parentheses would be a string and not the actual DB object, so I am at a loss.
