Prevent Duplicate Entry From Textbox Into Different Worksheet
Jun 12, 2009
I have a entry form in which i want to register customers. the first field is the customer number (which is unique(created by me) for every customer). This is TextBox 1 in the document. I would like to search for duplicates in worksheet 2, collumn A, when pressing "enter" to move from TextBox 1 to TextBox 2. A search for duplicates should start and a message should appear " duplicate found" if found, otherwise continue to TextBox 2 for further entry of information.
Please see my attached document for clarification.

I have a huge worksheet with 26 columns and 1200 rows. This worksheet is updated by 4 people everyday. Column C, H, N & R are updated daily by these 4 people so these are dynamic columns so to speak. I would like to have a VBA that informs that particular individual when he enters a duplicate data, maybe a popup saying duplicate entry.

I have created a userform with 3 text boxes. It also has three buttons - clear, Cancel and Generate record button.
User form takes entries in the three text boxes and on clicking the Generate Record button, the values of the three Text Boxes are inserted in Column A, B and C of sheet1. The columns keep on populating with new data on each submit in the row below the last record.
Now it is required to enter data only if the value entered in TextBox1 is new and has not been entered previously in column A. If textbox entry is already aviailable in column A, a message box of 'Record available' shoud be prompted and the text entry must not be allowed until the data entered in TextBox1 is not unique.

I have a userform with several textboxes and 2 comboboxes. The data that I need protected from duplication is based in the comboboxes. If I ignore the other fields and presume the following it may be easier to understand:
The comboboxes are populated by the data stored in sheet1 and when the userform is complete, the OK button populates all the data into sheet2
Combobox1 contains names eg, John, Julie, Bob etc
Combobox2 contains colours eg, Red, Blue, Green etc
I want the userform to allow the data to be entered into sheet2 only if it is not an exact duplicate of the choices in BOTH of the comboboxes
For Example
John Red
Julie Red
Bob Blue
John Blue
These are all ok, however, to try and enter John Red again would bring up a message box indicating a duplicate entry and prevent the data from being entered.

I have multiple worksheets of computer equipment, each worksheet is a group/department. Column H is the serial number column and the entries have to be unique. I have managed to create the code below which does find duplicates across worksheets.
When error message pops up about which sheet the duplicate already exists on, the duplicate entry is deleted and the cell is blank but the error checks again and reports the blank existing on another worksheet and then it is stuck in a loop. How can I ignore the blank or null.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim I As Integer
I = Sheets.Count
If Not Intersect(Target, Range("H2:H200")) Is Nothing Then
Do Until I = 0
If Application.IsError(Application.Match(Target, Sheets(I).Range("H2:H200"), 0)) Then
Else
MsgBox "That entry already exists in the " + Sheets(I).Name + " sheet"
Target.ClearContents
End If
I = I - 1
Loop
End If
End Sub

I am attempting to pick up a date with time entry on a worksheet and place it into a TextBox on a UserForm. Format on the sheet is mm/dd/yyyy h:mm AM/PM. The UserForm is placing the value as mm/dd/yyyy 12:00 AM. here is the
Private Sub UserForm_Initialize()
If Not Range("dDate").Value = "" Then
TextBox2.Value = Range("dDate").Value
TextBox2.Text = Format(DateValue(TextBox2.Text), "mm/dd/yy h:mm AM/PM")
Else
TextBox2.Value = ""
TextBox2.SetFocus
End If
End Sub
"dDate" is the named range where the date is sitting. The format is also set on the TextBox2 exit event. Can anyone see why only the date portion is being transfered with the default 12:00 AM for no time component of the value?

Is there a formula that will allow me to look for the existence of any number value in a row of one worksheet and then return a specific number value in a cell on another worksheet? For example, if the formula finds any number value it will always return the number 15 to a cell on another worksheet.

I have one main tab which I pull data from other various tabs. To match data the data, I create a "common unique ID", in other words I create a column on each tab and connect various cells with the ampersand.
So in each of the various tabs (and the main tab), I'll have a column with something like =A2&B2&C3
If the "unique ID" matches between the tabs it will pull back the desired phrase, or it will be left blank. (Just using an =IF(ISNA) formula)
If you have followed so far, on my main tab, I have a column for each of the various tabs. The information I am trying to match could be on any of the tabs, so I need a column using an =IF(ISNA) formula to attempt to match each tab. So, on the main tab, there are several columns which might have the phrase I am looking for. I use another ampersand function to add those columns. My problem is that occaisionally, what I am looking for is on multiple tabs. So, if I am normally pulling the phrase "Pending Loans Report" when a match is made, if it is on two tabs, the cell will add it twice "Pending Loans ReportPending Loans Report"
I realize this is confusing, so I attached a spreadsheet. The "main" tab I was referring to is sheet1. I really simplified it down to post here, but I think the main idea of my problem is still evident. The problem is line 15. Note how column M has "Pending Loans ReportPending Loans Report" - I'd like it to only say this phrase once. The macro pastes special values at the end, but I've highlighted some cells in red which show the formulas I used for that column. Columns N, O, P, Q, etc. all have virtually the same formula.

I have a worksheet that you can enter in
Forename, Surname, Area, D.O.B
This has a macro assigned that copies the data and pastes it into another worksheet at the next available row.
Now this works fine, but I want to be able to identify if the data already exists in the other worksheet then prevent it from being pasted and give an error message that the person already exists in the database.
Is this possible?

Option Explicit
Dim myCount As Byte
Dim myColumn As String
Dim myRow As Long
Sub Worksheet_Change(ByVal Target As Range)
myCount = 0
If Range("B" & myRow).Value <> "" Then myCount = myCount + 1
If Range("C" & myRow).Value <> "" Then myCount = myCount + 1
If Range("D" & myRow).Value <> "" Then myCount = myCount + 1
If Range("E" & myRow).Value <> "" Then myCount = myCount + 1
If myCount > 1 Then....................
The above code pops up the message box when a second entry is made within the specified range, but OK button does not function, contents are not cleared, and Excel locks up.

I tried to solve above problem using Data Validation formula. Data validation does not work if somebody copy paste the duplicate values,it works when somebody types duplicate values in next column. So if I want to enter lot of urls to a column then it is completely impossible to type so must have to copy paste from the browser. I have attached a sample sheet, howl to solve this problem either using formula or using Data validation in sample 1 and sample 2 respectively.

I am using a macro that copied a string from another app, and I would like to know if there is a way to remove the sign "_" (underscore) before it paste to the TextBox1?
I declare the textbox as : TextBox1.Value = DATA
When the macro run, it takes the info from the app and send the string DATA to the TextBox1.Value, however there is ugly _ from the data. I want to be able to remove that sign right after it paste into the TextBox1.

I have a created recording sheet (attached) for the purpose of recording moths. I send this sheet out to those recorders who live in my county and at the end of the year they send the filled in sheet back to me. Over time I have put safeguards onto the sheet to ensure that I get the cleanest data returned to me. However, there is still one area which is giving me problems - users entering duplicate records.
Some formula which will stop recorders from entering those duplicate records. There are many columns on the sheet which recorders have to fill in with information, but as far as the duplicate records are concerned it is where the same information is entered into columns C, F and J that I'm having a problem with. It would be great if, when the same information was entered in these columns that the affected cells were highlighted in some way and if an error message appeared saying 'Duplicate record, either delete or alter grid reference'
I have entered two test duplicate record on the 'macro moths' sheet of the attached file : Test Recording sheet.xls

I am working pivot tables off of one large excel spreadsheet for my data. I have multiple pivot tables on each of 5 worksheets. The problem is this. Every other week I am sent an updated spreadsheet with the same column names each week which I then copy and paste it into the spreadsheet of the last one. When I refresh the pivot tables, I end up with duplicate field sets. For example, on column in the original data sheet is gender. On the first sheet I went through and renamed the "M"'s and "F"s to be "Male" and "Female" so that it is better looking when printed. Now when i get the new information and copy and paste it to rplace the old, and refresh the pivot tables, I end up with "Male" "Female" AND "M" "F". Now the "Male" and "Female" fields are empty and the "M" and "F" fields have the information. Is this a result of me renaming the fields?

I have a form that information is entered in. At the end the user can then save the information in a spreadsheet by pressing a command button. The updating to the spreadsheet works, it is the part where the last entry is tested against the info on the form to prevent a duplicate entry that do not work.
I have tested that the program reads the info from the spreadsheet (see the commented lines).
I can attach the whole spreadsheet, but some of the entries on the form are linked to another spreadsheet that make it a bit cumbersome to attach two files.
VB:
Private Sub cmdUpdate_Click()
Dim lRow As Long
Dim ws As Worksheet
Set ws = Worksheets("TonnageInput")
