In the code where you ADD the items to the ListView:

Set li = LV.ListItems.Add(, , rs.Fields(fldname))

you will need to add a field (between the two commas, which is the KEY of
the entry (The Primary Key of the record).

This code asppears to be something that you have copied from soemwhere, and
you are now trying to chang the fuctionality to conform to something that
you need. This is rather dangerous to do when you do not fully understand
what the code is doing in the first palce.(The reason for this guess is that
this is a GETTING STARTED discussion, but this is fairly complex and reasonable
advanced code, so that the code seems somewhat out of place in a GETTING
STARTED discussion).

In the Table, from which you are retrieving the data, theere will be a field
(probbaly the first field in the record) which defines the PRIMARY KEY of
that record (a value which UNIQUELY identifies that record). This field's
value will serve as the KEY of the ListView item, and it is the value in
this field which should be used in the line which adds the line to the ListView
control. If this value is in fact a string, then you can use that value
precisely as is. If that value happens to be a Number (which it probably
is), then you will need to "convert" it to a string, usually accomplished
by simply appending a single character onto the RIGHT END of the value (like
this - assuming that the Primary Key of the record IS IN FACT in Field(0))

Set li = LV.ListItems.Add(,rs.Fields(0) & "K" , rs.Fields(fldname))

Then, in the Delete Line, you would have code like this:

cn.Execute "DELETE from sn where <KeyField> = " & Val(ListView1.SelectedItem.Key)

where <KeyField> is the NAME of the field (in your table) which holds the
Primary Key. This means that you MUST know the names of the fields in the
table, and MUST know which of the fields holds the Primary Key. (Clearly
if you know this field name, then you can use that field-name EXPLICITLY
in the line:

Set li = LV.ListItems.Add(,rs.Fields(<NameOfPrimaryKeyField>) & "K" , rs.Fields(fldname))
