Choose The Same Strings From Two List (Of String)?

Feb 24, 2012

I have two List(Of String).Both Lists contain duplicate strings. I want to pick out all the strings which are contained in both the Lists. For example:

List1 ={"10X100","10X100","10X100","50X100","50X100","100X100"}
List2 ={"10X100","10X100","20X100","50X100","50X100","100X100","200X100"}

So, the result should be: List3={"10X100","10X100","50X100","50X100","100X100"}.How to do this?

Add A String Item, Returned From Another Form To A List Box At A Specific Spot In Place Of Another?

Nov 22, 2010

there's a list-box with items, and say you want to modify an item in the middle of the list. You select that item and click "Modify" button and a new form appears with the previously selected item data from first form ready to be modified in a text-box. After modifying and clicking Ok the second form suppose to return that modified string to the first form and insert the modified string into the same spot instead of the originally selected item, so it looks like it was edited to the user.

Find In List / Remove Item And Ignore Case Of Characters In String

May 20, 2012

I'm having issues with finding something in list, and removing the item, ignoring the case of characters in string.

The code goes:
Dim listItems As New List(Of String)
Dim pattern As String = "AbC"
Dim array() As String
array = {"ABC", "abc"}
listItems.AddRange(array)

Here I'd like to remove all items from listItems, that are abc, no matter what case single characters of item are, including mixed case items. So in this example, every items should be removed
listItems.Remove(listItems.Find(Function(r) r = pattern))

If I change pattern to match the case of item, then item #2 gets removed:
pattern = "abc"
listItems.Remove(listItems.Find(Function(r) r = pattern))
How can I find item in listItems, ignoring the case characters in pattern?

Possible To Make List Box Item Height For Item Depending On Amount Of Lines That Item Contains?

Jan 1, 2012

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

Forms :: Choose Item From ComboBox And Save Selected Value To DataSet

Dec 23, 2009

I have a problem with a combobox. I have a form (with information about clients) with textboxes binded to a dataview. One of the columns in the dataview contains a number that tells me what kind of client it is. I don't my users want that my users have to fill in a number in a textbox, but I want them to choose a item from a combobox. De selected value should be the value that is actually saved in the database.

This is my
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
VerbindingMaken()
cmd.Connection = cnnVraagbaak
cmd.CommandType = CommandType.StoredProcedure
[Code] .....

De Datasource is the information in my combobox. With Databindings I'm trying to bind it to my dataset (or view, that doesn't work either) with clients. Every time I get a NullReferenceExeption. The moment I remove the line cbo.DataSource = dsRelatie.Tables("Relatiesoort"), I don't get an error, but it doesn't work either.

That dataset is filled (I've checked) and also the derived view. The column Relatiesoort exists. What do I have to do to make it possible for my users to choose an item from a combobox and save the selected value to the underlying dataset?

May 18, 2010

I'm relearning VB.net just for fun, so consider me new at this. I'm trying to write a program where the user can input a list of names or numbers, and the program will randomly pick one of those names or numbers. So far, I can get it to randomly generate numbers based on what I put in the code, but I don't know what I should use for the user to input the data, and how to code it so that the program will pick from that data.

Get Selected Item Index Or A Sorted & Grouped List Relative To Item Source?

Feb 12, 2011

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.

What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.

[code]...

As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

Add To A Combobox A List Of Item (not Every Item) In A Txt Located On A Server

Feb 13, 2011

my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".

Now I just want to make 3 radio buttons:

- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).

How can I do so?

To download the entire list in the combobox I do:

Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)

Comparing An Item In A List Against Other Items In The Same List In .NET?

May 30, 2011

I have a List(Of MyObj), and I want to iterate through that list and compare each element to all other elements in the same list, excluding (if possible) the same element. I have a solution that works, but it's slow and uses double For loops. It may possibly have also summoned Cthulhu from his sleep. This below is a sanitized version of what I have:

Dim MyList As New List(Of MyObj)({Obj1, Obj2, Obj3, Obj4, Obj5, Obj6})
If MyList.Count > 0 Then
For i = 0 To (MyList.Count - 1) Step 1
