try this, add a combo,listbox,command button

Code:

---

Dim Myvar()
Dim i, j As Integer

Private Sub Command1_Click()
List1.Clear
For j = 0 To i - 1
    List1.AddItem Myvar(j)
Next
i = 0
End Sub

Private Sub Form_Load()
Combo1.AddItem "a"
Combo1.AddItem "b"
Combo1.AddItem "c"
Combo1.AddItem "d"

For i = 0 To Combo1.ListCount - 1
    ReDim Preserve Myvar(i)
    Myvar(i) = Combo1.List(i) 'storing values
Next
End Sub

now if i again select the first column say description then the option hide should be cheked.
i.e how to maintain the previous state...

One easy way is to use bitwise operations
Supress=1:Hide=2:Lock=4
Each time one of the checkboxes are clicked, update the itemdata for the combobox item...

I don't know if your checkboxes are arrayed or each is an individual control name. I will assume the former. Adjust code as needed for control names

Code:

---

Private Sub chkOptions_Click(Index As Integer)
    ' each check box is indexed: 0, 1, 2
    ' update the itemdata to the new options
    Dim lOptions As Long
    if cboItems.Tag = "no update" Then Exit Sub ' see cboItems_Click()
    If cboItems.ListIndex = -1 Then Exit Sub
    lOptions = cboItems.ItemData(cboItems.ListIndex)
    Select Case Index ' toggle options
    Case 0 ' suppress
        lOptions = lOptions Xor 1
    Case 1 ' hide
        lOptions = lOptions Xor 2
    Case 2 ' lock
        lOptions = lOptions Xor 4
    End Select
    cboItems.ItemData(cboItems.ListIndex) = lOptions
End Sub

Private Sub cboItems_Click()
    Dim lOptions As Long
    cboItems.Tag = "no update" ' prevent checkboxes from updating itemdata
    lOptions = cboItems.ItemData(cboItems.ListIndex)
    chkOptions(0).Value = (lOptions And 1) ' supress
    chkOptions(1).Value = (lOptions And 2) \ 2 ' hide
    chkOptions(2).Value = (lOptions And 4) \ 4 ' lock
    cboItems.Tag = ""
End Sub

Edited: If you are already using the itemdata property of the combobox items, then an array would be a good alternative.
