Dynamic lookup on forms

To create a custom dynamic lookup on a form, override the lookup method on the control, and add the following code. This code allows you to select a year, but it should be clear what you need to modify to show something else:

public void lookup()
{
    Counter yearCount;
    List    valueList = new List(Types::String);

    for (yearCount = 0; yearCount < 5; yearCount++)
    {
        valueList.addEnd(strFmt("Year %1", year(SystemDateGet()) - yearCount));
    }

    SysLookup::lookupList(this, valueList, "List of years");
}
