{
// Get the currently selected manufacturer from the combo box
var selected = comboBoxCorporation.SelectedItem;
buttonProductStatsAndRetailerStats.Enabled = false;
buttonSummariseRetailerStats.Enabled = false;
buttonSummariseProductStats.Enabled = false;
// Do we have one?
if (selected != null)
{
// Extract the combo record
var corporation = (ComboBoxCorporrationItem)selected;
// Do we have one?
if (corporation.Corporation != null)
{
// yes
// Make this on a seperate thread so that the UI continues
to work
var thread = new Thread(MigrateProductStats);
thread.Start(corporation.Corporation.Id); // This enables me
to pick the manufacturer that we are summarizing for
}
}
}
private void MigrateProductStats(object corporationIdObj)
