Salutare,
Sper sa gasesc o solutie aici ca imi storc creieri si google ul de 3 zile in speranta de a gasi o solutie.
Folosesc un datagridview pt afisarea unor date stocate intr o baza de date MySql

Totul merge ok. mai putin refresul informatiilor din view.
Informatiile sunt aduse din baza interogate in imidiate window dar nu sunt afisate.
codul arata cam asa

Public Shared Sub OnTimedEvent(ByVal source As Object, ByVal e As ElapsedEventArgs)
    Dim query As New imp_SQL
    Dim impDATA As New imp_SQL()
    Dim BindingSource1 As New BindingSource()
    Call query.ValuesSQL(1)
    BindingSource1.DataSource = imp_SQL.lvi
    FormAdmin.DataGridViewDataReq.DataSource = BindingSource1.DataSource
    BindingSource1.ResetBindings(False)
End Sub
lvi este o globala care stocheaza inf din baza de date.

O zi buna.

Cred ca m am grabit putin.
Cand interoghez BindingSource1.DataSource, este ok toate informatiile sunt acolo si sunt modificate (valorile le modific manual in baza MySQL).
imp_SQL.lvi este un DataTable.
Vre o idee ?

S a rezolvat.
Deci cand apelam functia OnTimedEvent o faceam printr un
Dim Timer As New Timers.Timer(60000) '1000 ms
    Timer.AutoReset = True
    AddHandler Timer.Elapsed, AddressOf qrt.TimerElapsedHandler
    Timer.Start()
care cred ca crea un Thread si bloca toata aplicatia.

Solutia una neasteptat de simpla :
Din toolbox => Components exista un Timer care poate fi setat sa declanseze la un interval stabilit.
