Few Questions...

Hey guys, i want to ask you few questions...

1.In my program I have 2 textboxes.In first textbox user need to put some number.Let's say he put number 10, then in other textbox program need to write numbers from 1 - 10, like this:

Code:

---

1,2,3,4,5,6,7,8,9,10

---

If he put 20 in first textbox, in second textbox it should be:

Code:

---

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20

---

2.I need to do this...
Import text file to listbox.
Export items in listbox as text file.

I don't see one question let alone a few.

You've told us what you want to do, what are you struggling with?

You can use a for loop to create the output you are looking for. Take a look at an example here:

The my.computer.filesystem can help you read and write files:

Will the user ever edit that sequence of numbers 1,2,3...etc? If not, the second textbox should actually be a label.

That doesn't work because between every number i need comma.

to output a sequence of numbers:

vb Code:

textbox2.text = "1"
for x as integer = 2 to cint(textbox1.text)
    textbox2.text &= "," & x.tostring
next

to load a listbox from a txt file:

vb Code:

listbox1.items.addrange(io.file.readalllines(filename))

to save a listbox contents to a txt file:

vb Code:

Dim items(listbox1.items.count - 1) As String
ListBox1.Items.CopyTo(items, 0)
IO.File.WriteAllLines(filename, items)

Thank you Paul it worked!

Now I have one more questions....

1.Is this possible....

I have a textbox and button.

Starting text in textbox is:

Code:

---

I am from Croatia

---

Is it possible that when i press button that it removes word "Croatia" and every word after word "Croatia" from this textbox.

Example:

This is in textbox:

Code:

---

I am from Croatia vdvhdfgdsfgsd

---

I need to remove word "Croatia" and every word after it(In this case it is "vdvhdfgdsfgsd")

Have a look for the IndexOf and SubString functions of a string. Look them up in MSDN or similar and you will get enough examples to help you.

If the user isn't going to select the word, you can do this, if not, just tweak it a little bit ;)

vb.net Code:

Public Sub DeleteWords()
        Dim sentence As String = "I'm hot Croatia and I'm bored as hell"
        Dim words As String() = sentence.Split(New Char() {" "c})
        Dim check As Integer = 0
 
        For i As Integer = 0 To words.Count - 1
            If words(i) = "Croatia" Then
                check = i - 1
            End If
        Next
        For c As Integer = 0 To check
            MsgBox(words(c) & " ")
        Next
    End Sub

Hope it helps :)

That's way more complicated than required. All you need to do is check the position of the word "Croatia" in the string using the IndexOf method, and then extract the first part using the SubString method. It can be done in one line.
