Remove Duplicates From ComboBox


Ok my combo boxes get filled using a database on formload.

Is there a way to see if something is already in the combo box therefore not adding it again ? (Assuming this would be slow?)

or does anyone have a quick function to remove duplicates?

Remove All Duplicates From Array
First...I have an array of a number that varies...between 2 and 14. I want to be able to check if all the current number values in the array are of the same value. Example:
i have an array: Temp(6) as integer
every number in the 7 slots for temp = 9
i need way way to check if all of them are equal. But not always is the number going to be a 9, it could be anything from 1 to 14...Im kinda stumped on this...i think i would have to do some sort of loop...like
for i = 0 to ubound(temp)
if temp(i) = temp(i+1) then
if temp(i+1) = temp(i+2) then
etc
next
but thats not working to well for me...can anyone help me out a bit.
If you need more info, please repond, or if it isnt clear enough, please respond.
THanks for looking

Use Of Group By To Remove Duplicates...?
Hello everyone,

I am a newb at SQL so please bare with me when I ask:
Will using a group by clause in a SQL query return only unique values in the field that the query is being grouped by?

For example If I use:

Code:
select ChipName, WaferName, Date
from tblChipInfo
group by ChipName;

Will my query only display values for WaferName and date where the ChipName is unique?

I have attempted executing a statment similar to this but am getting an error stating that the other field names in the select statement are not part of aggregate functions.

Please help...

Remove Duplicates From A Listbox?
Hi,

Here's an example listbox:

Quote:




Hello World
Hi World
Hello World






How would I go about removing just one of the "Hello World" entries?

And this also needs to work with multiple duplicated text and without me specifying the duplicates.

Basically I need some code to check through a long listbox, find duplicates and remove them. (if there's 2 duplicates, remove 1, if theres 3 duplicates, remove 2 etc. etc.) I hope I've explained that enough for you to understand.

Remove Duplicates In Array
Hi guys i have some code parsing a log i have extracted the lines i want but appart from time stamp there are many duplicates. i have removed the time stamp so now they are duplicates how can i only write to a text file a line from the array if if does not allready exist? but if it does exist then move to next entry so i only end up with one off entries.

like the

21:02:06 11:16:13 john checked in
22:02:06 13:01:59 john checked in

looks like this

john checked in
john checked in

only want to write one entry to the text file and move on to the next.


thanks in advance

Find And Remove Duplicates In 1 Table?
Hi,

The Access table, tblOwners, has about 200,000 owners. It's been filling for a couple of years. I just took over someone's position.

The SQL statement: SELECT DISTINCT OwnerID FROM tblOwners
returned about 180,000 records. So, I've got about 20,000 duplicates!

Question: Before I continue writing a VB .exe that uses the database, I want to remove all the duplicate records from the table.

Is there a way to clean it up?

Many thanks,
Chris.

P.S. I've searched through this post on the subject and found I could place the DISTINCT records into another table, and then delete the tblOwners. Is there another way?

Remove Duplicates And Sort Array
I have a large string array and I need to remove the duplicates and sort the array alphabetically.

I know I could do this through a good bit of code and some loops, but I've found more than a few times what I went about coding from scratch was already available in a function.

My best bet for fastest way to sort is through a list box invisible to the user. Is there a better way?

The only way I know of to remove the duplicates in the array would be with a nested loop searching from the beginning each time until it's determined that the string is unique and then on to the next string.

I'm guessing VB provides a quicker way.

Getting Rid Of Duplicates In ComboBOX
Alright, in my Database I have many samples that are frozen on different dates.

What I'm trying to do is create a combo box with all the dates included. And when a date is selected, display all the samples that were frozen on that date in a listbox.

However, I've run into a problem already in that when I choose to make the combo box from the date column of my table, it takes all the dates, even the duplicates. For example, if there are 3 samples frozen on june 20th. there will be 3 june 20th's in the combo box. How can I get rid of this. I tried the removeitem property but it's not working. It says I'm not able to use this property when the combo box is connected to a data table or something when I go to help. ANY SUGGESTIONS?

Thanks.

Getting Rid Of Duplicates In Combobox
Hi
Well, the title says it all.
I am populating a combobox with the content of a table.
I would like to get rid of all the duplicate entries in my combobox.
Is there a simple way to do so ?

Duplicates In Combobox

Combobox Duplicates After Save...
I have a combobox that is populated with the code below. When the program is first run, the combobox doesn't have duplicates, but after a save is made, it will duplicate each entry once. I'm sure it's something easy I'm missing, I just haven't found it, yet.


Code:
rs.Open "SELECT DISTINCT VENDOR_ID FROM RECEIVING_INSPECTION", conn, adOpenKeyset
If rs.RecordCount > 0 Then
rs.MoveFirst
Do While rs.EOF = False
cmbVendor.AddItem rs!VENDOR_ID
rs.MoveNext
Loop
End If

Prevent Combobox Duplicates
I know how to search both a listbox and a combo box for duplicate entries and remove them.

What I would like to do is prevent a duplicate from ever getting entered in the first place.

How would I do that?

Combobox: Automatch Item, Select In Other Combobox, Remove From Both
I have 2 comboboxes and a listbox. I want the user to select an item from one combo, with then matches the item to its corresponding item in the 2nd combo, then add both to a list box. The user can either select from the 1st combo or from the 2nd...either one will match to the corresponding item in the other. Both comboboxes also have to be autocompleting. Once the selection is added to the listbox, the user can remove it which will delete the item from the list and add them back into the appropriate comboboxes. I have this working except for one thing.

When autocompleting, if the user types in what they want and its found and they hit ENTER, I am getting an error when trying to remove the item from the combos. It tells me the index is invalid and sure enough, when I check what the index is, its -1. It seems that the user isn't selecting an item in the combo even though its matched.

This is what I tried. It works if an item is clicked or chosen by pressing the up/down arrows. It also works if they type what they want, its matched, then they press up/down or some other number but will NOT work if they just type it, its found and they hit enter:


Code:
Private Sub cmdAdd_Click()
List1.AddItem cmbo(0).Text & " " & cmbo(1).Text

cmbo(0).RemoveItem (cmbo(0).ListIndex)
cmbo(1).RemoveItem (cmbo(1).ListIndex)

End Sub

Oddly, if I put the opposite combo item to be deleted, it works...so, if I just selected something from combo 1, the following works:


Code:
Private Sub cmdAdd_Click()
List1.AddItem cmbo(0).Text & " " & cmbo(1).Text

cmbo(0).RemoveItem (cmbo(1).ListIndex)
cmbo(1).RemoveItem (cmbo(1).ListIndex)

End Sub

Any ideas anyone? Perhaps I need to post the function I use for autocompleting? Let me know please...

Checking For Duplicates In Combobox History...
Hi...

I have a combo box which stores the history of folder paths i've browsed to. I have no problems adding paths to a combo box, I just can't get my brain around the code for checking for duplicates...I tried searching the vbCity for an answer to no avail...

This is my code...It doesn't work, because it only checks the current value in the string, not the entire combo box contents:

Code:cboPath.Text = strPathVar
For i = 0 To cboPath.ListCount - 1
    If cboPath.List(i) <> strPathVar Then
       cboPath.AddItem strPathVar
    Else
       'Do nothing
    End If
Next

Thanx in advance...

Remove Item From ListBox Or ComboBox By String
OK,

Believe me, I've looked high and low for a way to do this. I'm stumped. I have the same problem with ComboBox and ListBox.

If I .AddItem ("SomeText"), I need to remove the same item, but with just using the "SomeText" as a starting point.

The .RemoveItem only takes an Integer Index. How can I remove by String instead?

Thanks!

ComboBox Not Working Properly...need To Remove Read-only Property
I have a ComboBox that has the Style set to 2-Dropdown List and I'm very angry with it right now. Cause even tho I can type in a character that would match something on the list, like an a - and the word apple would appear, or b - and the word bear would appear (of course if they were in my list)...I cannot have my ComboBox make it equal to nothing because the property on it is Read-only!

So let's say I start a new order and I have all my text boxes erased with the data...I can't make my
Code:
combo box cmbList.Text = ""
Any help is appreciated!
