Ive been struggling with finding the checked items inside a checklistbox

So far i only figured out how to use a selected (the blue select) instead of the checkboxes to drag out information from these, how do i use the check function? :)

Below is the code for selected type
Dim valgetkunde As String = Me.checkedlistbox.SelectedItem

You can access the checked items using the CheckedItems collection.  :)
For Each CheckItem As String In Me.CheckedListBox1.CheckedItems
    Debug.WriteLine(CheckItem)
Next

Dim strArray(CheckedListBox1.CheckedIndices.Count()) As String

        For intCount As Integer = 0 To CheckedListBox1.CheckedIndices.Count - 1
            If CheckedListBox1.GetItemCheckState(intCount) = CheckState.Checked Then
                strArray(intCount) = CheckedListBox1.Items(intCount).ToString

            End If

You have to reference each string array item individually.

msgbox(strArray(0)), msgbox(strArray(1)), etc...

I still dont understand how this will make a variable with the data from the checklistbox

I need the checked item data (or values)

I have customers in the checkedlistbox, when i check "Jimbo Jupiter" in my checked listbox i need a variable that contains this string

Your checkedlistbox can hold more than one checked item.  Thus it is exposed as a collection.  Since you wish to load all items from chdlistkunde into an array named kundetabell, you can do that without splitting from a string.
Dim kundetabell(chdlistkunde.CheckedItems.Count - 1) As String
chdlistkunde.CheckedItems.CopyTo(kundetabell, 0)

If your checkbox has type different than string then you will need to declare the array as a differant type.
Dim strArray(CheckedListBox1.CheckedItems.Count - 1) As String
CheckedListBox1.CheckedItems.CopyTo(strArray, 0)
