View 4 RepliesCannot Remove Rows In Datagridview
Aug 11, 2011My datagridview is bound to a data table. I want to filter the datagridview without affecting data table. I know one way is to use bindingsource, but binding source will use column names in its filter. But I want to enable users to enter any string in a textbox to filter. So I pass datagridview by reference to a function PassFilter which removes unwanted rows in datagridview. I can see that it does execute rows removal in datagridview. But the problem is that when datagridview is shown on the form, it is unchanged, the same as the data table. I do not understand why rows are not removed on datagridview The code is as follows:

This code seems right but its not working. It's giving me an "Index out of range" error. If I change the upper bound of the loop to "(Count - 2)" the code works, it just deletes all except 1 selected row. So can't figure out why "(Count - 1)" doesn't work.

[2008] Duplicate Rows In DataDridView?
May 26, 2008I am looping through a file and I am populating a datagridview with values. I have this part done, and it works just fine. My problem comes in when I try to remove duplicate rows from the DataGridView. I would like the code to increment a cell if a duplicate row is found and then remove the duplicate cell. For instance if the program comes across 2 instances of "duplicated value" in the DateGridView, I would like the second instance to be removed and then a value of 1 added to the first instances row, 4th column. I understand most of it, but I just can't get the darn loop(s) working correctly. Iguess my theory is to compare the first row to the last row. if there is a duplicate, then remove the duplicate and add "1".Then I should move onto the next item from the top. This would loop until all items have been checked. I have been messing with this for a while now and I just keeps getting worse.

Array - Remove Duplicate And Original?
Apr 11, 2010I've come unstuck on a certain point. I am trying to find a way to compare two lists and output only lines which are unique. In other words, remove both occurrences of duplicate lines.I'm relatively inexperienced with VB.NET, but this is how far I have managed to come;
Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim LinksList1, LinksList2 As String
LinksList1 = Replace(RichTextBox1.Text, "#vch", "") : LinksList2 = Replace(RichTextBox2.Text, "#vch", "")
[code]....
1) search the array to find duplicates and add them to a second array, then have a second pass to remove anything which matches the second array.
2) search the array for one duplicate and store it, then search the array again to remove the duplicates, and run that process until there are no more duplicates.
Then again, I could be going about this completely the wrong way. If that's the case, feel free to knock some sense into me.

View 7 RepliesLINQ To DataTable, Finding Duplicate Rows?
Jul 5, 2011Using the following DataTable:

d.Columns.Add("Product", GetType(System.String))
d.Columns.Add("Value", GetType(System.Double))
[code]....
I'm trying to use LINQ to identify if there are more than one of any type of product. In SQL, this would work something like:
SELECT Product FROM SOME_TABLE HAVING COUNT(*) > 1
I can't for the life of me work out how to do this in LINQ. I was following someone who did something like this:
Dim q = From row In d.AsEnumerable()
Group row By New { column1 = row("Product"), column2 = row("Value") }
Into grp

But I get an error when I try to actually use 'q'. how I can make this work?
Removing Duplicate Rows In A Textfile Then Add To Datatable?
Aug 16, 2010I am reading a textfile and extracting information from each line. For example string1 and string2. I am then writing these string to a datatable.
However, sometimes there will be repeats in string1 and string2.
If there are repeated lines I would like to be able to delete the repeating line and add a counter to find the total number of repeating lines.
so if a string repeates 3 times I would like there to be a column with a 3 displayed next to the line in my datatable.

C# - Remove Duplicate Char On String (more Than 3 Occurrences) Using Regex?
Jan 13, 2012I'm sorry if it's a duplicate of some question but this is specific on Vb.Net Regex function.
I need to remove any occurrence of 3 or more duplicate characters on a given string. For example:
Dim strTmp As String = "111111.......222222 and 33"
Dim output As String = Regex.Replace(strTmp, "????", "")
Debug.Print(output)
The "????" part I guess should be the Regex expression, which I must assume I know almost nothing about.
I don't know if that's the correct syntax. But I need the output to come as:
"1.2 and 33"
