As I see it,  a snapshot is some information retrieved from a table that cannot be updatable and a dynaset can be updatable.
Well, in the relation of this two tables can i retrieve information of the first one (by a snapshot) for some fields (that I don't want to update) and relate them to the  second information of a second table that I must update ?
Another question: How can I format a text box for currency?

I don't understand what you mean by 'relate'.  Are you planning on opening up a 3rd recordset equal to a join of the two tables?  Are you going to loop through one table, finding related values in another table?  More information would be helpful.

Also -- you probably want to post the text box question seperately.

Open the snapshot first, loop through it a record at a time and create new dynasets for each record in the snapshot.

DIM SS as RecordSet
DIM DS as RecordSet
Dim WS as WorkSpace
Dim DB as Database
' Create Microsoft Jet Workspace object.

Set ws = CreateWorkspace("", "admin", "", dbUseJet)
Set db = ws.OpenDatabase("MY.mdb", True)
'Open Snapshot first
sql = "SELECT * FROM tblTableA"
Set SS = DB.OpenRecordSet(sql, dbOpenSnapshot)
Do until SS.EOF
  sql = "SELECT * FROM tblTableB WHERE tblTableB.Key = " & Cstr(SS!tblTableA.Key))
  Set DS = DB.OpenRecordSet(sql, dbOpenDynaset)
  ' look at your dynaset here
 If DS.EOF Then
    ' nothing found
  Else
    ' something found
    DS.Edit
    DS!FieldA = "new value"
    DS.Update
  Endif
 DS.Close
  Set DS = Nothing
  SS.MoveNext
 ' go to next record in snapshot
Loop

Hi asimoes,
Regarding the second question, try this one.

MyStr = Format(5459.4, "$##,##0.00") returns $5,459.00

Also go to keypress event of text box and write code so that it allows only numbers to be keyed in the text box.

Regards,
mskannan
