Problem CheckedListBox

Hello,

So my problem is this. I am inspired by a code on another site, but I understand that. The problem is in this code, to manage a list, the code uses the ListBox, but the disadvantage is that you can select only one box, or I need to select multiple CheckedListBox so I replaced, I am is perfect, BUT I can not update the code. These are the two errors obtained:


Error: "

Code:

---

Error 3 'Items'is not a member of 'System.Windows.Forms.GroupBox'.
Error 2 'SelectedItem'is not a member of 'System.Windows.Forms.GroupBox'.

---

Here is the corresponding source code (an example is because there are more lines in the same genre):

Code:

Code:

---

Me.list_cc.Items.Clear()
Me.list_cc.SelectedItem

---

How can I get the same effect as 2 functions with CheckedListBox? Many thank you

list_cc is obviously your groupbox + not your CheckedListBox
use the right name + it'll work

Thanks but have you a example , i don't understand

it's basic beginners vb. if you don't understand you should try a tutorial first:

http://www.homeandlearn.co.uk/NET/vbNet.html

Yes but my CheckedListBox's name is list_cc . And i want a fonction in CheckedListBox = Items or SelectedItem'

i can't give you an example because it really isn't clear what you're trying to do.
if you want to upload your project i'll have a look

Yes i want a example please . It's clear but i don't see how do .

please read post #6 again

i said i can't give you an example

Sorry but for my code :

vb Code:

Me.list_cc.SelectedItem

How i can do now ?

ok post your full code

This is my code for error error 'SelectedItem' :

VB Code:

If Not Me.list_cc.SelectedItem Is Nothing Then
            'Retrouve le film avec ce nom
            For Each ccALister As ccinfo In _Listecc
                If ccALister.Nom = Me.list_cc.SelectedItem.ToString Then
                    'L'insère dans une variable globale
                    Me._ccEnVisualisation = ccALister
                End If
            Next
        End If

This is my code for error error 'Item' :

Vb Code:

Me.list_cc.Items.Clear()

My code is too long for post

i think we have a language barrier.
we need to see the relevant code if you have any chance of help + if it's all in french, i probably won't be able to help you

Code in english :

Vb Code:

If Not Me.list_cc.SelectedItem Is Nothing Then
            'Found the movie with that name
            For Each ccALister As ccinfo In _Listecc
                If ccALister.Nom = Me.list_cc.SelectedItem.ToString Then
                    'Inserts in a global variable
                    Me._ccEnVisualisation = ccALister
                End If
            Next
        End If

that isn't the relevant code

we need to see the lines that are causing the errors

also if vb says list_cc is a groupbox it probably is a groupbox

It's the only code for error SelectedItem

Vb Code:

If Not Me.list_cc.SelectedItem Is Nothing Then
            'Found the movie with that name
            For Each ccALister As ccinfo In _Listecc
                If ccALister.Nom = Me.list_cc.SelectedItem.ToString Then
                    'Inserts in a global variable
                    Me._ccEnVisualisation = ccALister
                End If
            Next
        End If

The rest is much too long for post . If you explain me the error , i can solve
the error for the rest of the code

in your form designer, click on the list_cc listbox(???) + take a screenshot that shows the selected listbox + the properties window + post it in this thread

Like paul said, unless you debug the code and locate the error, we won't be able to know the cause of error. You have something like " .Nom " in your code. What is it ?

Forget it, thank you but it's too complicated .. By cons how do I select all the boxes. I have this function but it does to selection:

CheckedListBox1.SetItemChecked (0, True)

Seconde question, I have fichier.vb [Design] but i have delet onglet , how I can to re-open this ?

i take it you solved the list_cc problem then?

vb Code:

For x As Integer = 0 To CheckedListBox1.Items.Count - 1
    CheckedListBox1.SetItemChecked(x, True)
Next

what's that in english?

I had a tab Fichier.vb [Design]. But without express I cancel tab, how to restore?

in your designer you have a project explorer window on the right. doubleclick Fichier.vb

Yes of course ^^ Thanks you . Sorry for my bad english .
