Example

The following sample C# code illustrates how to define, query, and use the wwActualChar object.

The example searches for Lot_123 of the Vinegar material in the BulkTk1 unit and changes the value of the actual pH characteristic to 4.3.

private void ChangeButton_Click(object sender, EventArgs e)

if (LocMatUnits == null)

return;

for (int ut = 1; ut <= LocMatUnits.Count; ut++)

{

MatUnit = (wwMaterialUnit)LocMatUnits.Item(ut);

if (UnitsLsb.Items.Count > 0)

if (MatUnit.UnitName == UnitsLsb.SelectedItem.ToString())

break;

}

MatUnit.QueryCLBs();

MatClbs = (wwMaterialCLBs)MatUnit.MaterialCLBs;

for (int i = 1; i <= MatClbs.Count; i++)

{

MatClb = (wwMaterialCLB)MatClbs.Item(i);

if (i == (System.Convert.ToInt16( lotTrackingLsv.SelectedItems[0].SubItems[0].Text)))

break;
