VBA to delete selected item in list box

I want to delete items selected from a list box in my form.
I have a piece of code that worked well in another form and tried to make it work here, but it isn't working.
I get the following error message "You can't assign a value to this object"

Am I missing something really simple?

Private Sub btnDelete_Click()

Dim frm As Form
Dim ctl As Control
Dim db As DAO.Database
Dim strsql As String

Dim i As Variant
Set frm = Forms("frm_SubTaskOrders")
Set ctl = frm![lstSubTaskOrders]


Set db = CurrentDb




For Each i In ctl.ItemsSelected
     strsql = "DELETE FROM SubTaskOrders WHERE"
                [STOid] = " & ctl.Column(0, i)" & " AND [STONo] = " & ctl.Column(1, i) & " AND [STOName] = " & ctl.Column(2, i) & " And [Toid] = " & ctl.Column(3, i)
     db.Execute strsql, dbFailOnError
Next i
ctl.Requery



CurrentDb.Execute strsql, dbFailOnError



End Sub

Open in new window


Thank you!

Try this
 strsql = "DELETE FROM SubTaskOrders WHERE " & _
                "[STOid] = " & ctl.Column(0, i) & " AND [STONo] = " & ctl.Column(1, i) & " AND [STOName] = " & ctl.Column(2, i) & " And [Toid] = " & ctl.Column(3, i)
 

Open in new window

If any of parameters is string, double quotes before and after it:
chr(34) &  ctl.Column(2, i) & chr(34)

Now I am getting a different error:

Syntax error (missing operator) in query expression '[STOid] = 9 AND [STONo] = 2 AND [STOName] = Tech Coordination AND [TOid] = 1 AND [OrderNumber]=2'

It appears to be pulling information from the table in this error.

Also, I forgot that I had one more field I needed to delete information from in this table (OrderNumber), so I added it to the list box and to the code. So this is what I have:

Private Sub btnDelete_Click()

Dim frm As Form
Dim ctl As Control
Dim db As DAO.Database
Dim strsql As String

Dim i As Variant
Set frm = Forms("frm_SubTaskOrders")
Set ctl = frm![lstSubTaskOrders]


Set db = CurrentDb




For Each i In ctl.ItemsSelected

 strsql = "DELETE FROM SubTaskOrders WHERE " & _
                "[STOid] = " & ctl.Column(0, i) & " AND [STONo] = " & ctl.Column(1, i) & " AND [STOName] = " & ctl.Column(2, i) & " And [Toid] = " & ctl.Column(3, i) & " And [OrderNumber] = " & ctl.Column(4, i)
 

     db.Execute strsql, dbFailOnError
Next i
ctl.Requery



CurrentDb.Execute strsql, dbFailOnError



End Sub

try changing your strsql with this


strsql = "DELETE FROM SubTaskOrders WHERE " & _
                "[STOid] = " & ctl.Column(0, i) & " AND [STONo] = " & ctl.Column(1, i) & " AND [STOName] = '" & ctl.Column(2, i) & "' And [Toid] = " & ctl.Column(3, i) & " And [OrderNumber] = " & ctl.Column(4, i)
