[RESOLVED] Help!!!! Please !!

Hi, right now im working on just a super simple - basic program. I would explain it but it really doesnt matter all that much....

so what i need help with is, i need to get ALL the words/items in the listbox to go INTO a textbox... i know how to do it the opposite way with lstbox1.items.add(txtbox1.text) - etc.... but it need to figure out how to make it go from LISTBOX to TEXTBOX. i've already tried stuff like "txtbox1.text = lstbox1.text" - that doesnt work, i've also tried "txtbox1.text = lstbox1.items", and just stuff like that, i've probably tried like 10 different things but none of them work :(

im using VB 2008 Express Edition

PLEASE HELP, i'll put lots of <3<3<3<3<3<3's if you do :)

Re: Help!!!! Please !!
this should be simple enough
i assume listbox is called ListBox1 and textbox is called TextBox1 and also that ur textbox is multiline
vb Code:
```
For Each item In ListBox1.Items
            TextBox1.Text = TextBox1.Text & item & Environment.NewLine
        Next
```

Re: Help!!!! Please !!
I've asked the mods to move this thread to the VB.NET forum. Always post in the most specific forum appropriate to the topic. Also, please provide descriptive titles for your threads. If everyone who wanted help use "Help" as the title then every single thread would be entitled "Help" and there would be nothing to distinguish them so we'd have to open every single one to know which was relevant.

vb_ftw's code will get the job done but it's not the best option. If you need to update a control its preferable to do it only once, so if you have multiple data items, you should combine them into one first, then update the control. There are various ways you could go about this but, assuming that there's either no data already in the TextBox or you want to replace the existing text, I'd do it this way:
vb.net Code:
```
Dim lines(Me.ListBox1.Items.Count - 1) As String
 
Me.ListBox1.Items.CopyTo(lines, 0)
Me.TextBox1.Lines = lines
```

Welcome to VBForums :wave:

It isn't clear from your post which version of VB you are using for this... can you tell us which version the Help -> About screen shows? (likely to be something like: VB 6.0, or VB 6.3, or VB 2008, etc)

I've not used VB6 but I don't think "lstbox1.items.add(txtbox1.text)" would be valid in anything other than VB.NET would it?

hmm i tried this just now and this line:

txtalpha.Text = txtalpha.Text & item & Environment.NewLine

got highlighted and an error saying:

Operator '&' is not defined for string "" and type 'ObjectCollection'.

idk what most errors mean, i'm not the best in vb and im still just starting

If you could tell us what VB version you are using, that would be a start.

Re: Help!!!! Please !!

Me.ListBox1.Items.CopyTo(lines, 0)
Me.TextBox1.Lines = lines[/HIGHLIGHT][/QUOTE]

i also tried your code and changed listbox1 and textbox1 to my names of those items

Code:

Dim lines(Me.lstalpha2.Items.Count - 1) As String Me.lstalpha2.Items.CopyTo(lines, 0) Me.txtalpha.Lines = lines

and with that i got this highlighted:

Me.lstalpha2.Items.CopyTo(lines, 0)

with the error message:

"Attempted to access an element as a type incompatible with the array."

the code makes sense though, i just cant figure out whats wrong :(

Re: Help!!!! Please !!

thanks for moving the thread :) i'm kinda new to the forums so i didnt know exactly where to put it :P.

anyways, anyone know how i can do this? the other 2 comments regarding code didnt work :(

Re: Help!!!! Please !!

how do you load your listbox? manually or from a datasource?

here's 3 possibilities:

vb Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    'databound
    TextBox1.Lines = Array.ConvertAll(ListBox1.Items.Cast(Of DataRowView).ToArray, Function(d As DataRowView) d.Item(ListBox1.DisplayMember).ToString)
End Sub
 
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    'integer
    TextBox2.Lines = Array.ConvertAll(ListBox2.Items.Cast(Of Integer).ToArray, Function(i) i.ToString)
End Sub
 
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
    'string
    TextBox3.Lines = ListBox3.Items.Cast(Of String).ToArray
End Sub

[/HIGHLIGHT]

im using a textbox to input what i want into the listbox... then i hit a button to alphabetize the listbox and take the words (now alphabetized) and insert them into the textbox...

I tried to use your code:

Code:

'string txtalpha.Lines = lstalpha2.Items.Cast(Of String).ToArray

because the "string" option seemed most fitting...

anyways once i copied it and inputted the names of my textbox and lstbox and ran the program i got this part highlighted:

txtalpha.Lines = lstalpha2.Items.Cast(Of String).ToArray

and the error read:

Unable to cast object of type 'ObjectCollection' to type 'System.String'.

:( your code seems to make sense to me, but i dont understand why it doesnt work...

Re: Help!!!! Please !!

You can find it in project properties.
It's either 2.0, 3.0, 3.5 or 4 client profile (or something like it).

Re: Help!!!! Please !!

which button should add the list items to the textbox?

Re: Help!!!! Please !!

this worked for me:

vb Code:

Public Class crmalpha
 
    Private Sub cmdalpha_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdalpha.Click
 
        lstalpha2.Items.Add(lstalpha.Items)
 
        lstalpha2.Sorted = True
 
        txtalpha.Lines = lstalpha.Items.Cast(Of String).ToArray
 
    End Sub
 
    Private Sub cmdadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdadd.Click
 
        lstalpha.Items.Add(txt1.Text)
 
        txt1.Text = ""
        txt1.Focus()
 
 
    End Sub
 
    Private Sub cmddelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmddelete.Click
 
        lstalpha.Items.Remove(txt1.Text)
 
        txt1.Text = ""
        txt1.Focus()
 
    End Sub
 
    Private Sub lstalpha_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstalpha.Click
 
        txt1.Text = lstalpha.Text
 
    End Sub
 
End Class

Re: Help!!!! Please !!

ok i found it. you want to display the sorted items from lstalpha2 in the textbox:

vb Code:

Private Sub cmdalpha_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdalpha.Click
 
    lstalpha2.Items.AddRange(lstalpha.Items.Cast(Of String).ToArray)
 
    lstalpha2.Sorted = True
 
    txtalpha.Lines = lstalpha2.Items.Cast(Of String).ToArray
 
End Sub
