create a dialog with custtable fields

Hi Friends,

         Today we will create  a dialog with custTable fields and auto populate the fields using the methods,

1.  In AOT, create a new class named CustSelect with the following code:
class CustSelect extends RunBase
{
    DialogField fieldAccount;
    DialogField fieldName;
    DialogField fieldGroup;
    DialogField fieldCurrency;
    DialogField fieldPaymTermId;
    DialogField fieldPaymMode;
}
public container pack()
{
    return connull();
}
public boolean unpack(container packedClass)
{
    return true;
}
protected Object dialog()
{
    Dialog          dialog;
    DialogTabPage   tabGeneral;
    DialogTabPage   tabDetails;
    DialogGroup     groupCustomer;
    DialogGroup     groupPayment;

   ;
    dialog = super();
    dialog.caption("Customer information");
    dialog.allowUpdateOnSelectCtrl(true);
    tabGeneral      = dialog.addTabPage("General");
    fieldAccount    = dialog.addField(
        typeid(CustAccount),
        "Customer account");
    fieldName       = dialog.addField(typeid(CustName));
    fieldName.enabled(false);
    tabDetails      = dialog.addTabPage("Details");
    groupCustomer   = dialog.addGroup("Setup");
    fieldGroup      = dialog.addField(typeid(CustGroupId));
    fieldCurrency   = dialog.addField(typeid(CurrencyCode));
    fieldGroup.enabled(false);
    fieldCurrency.enabled(false);
    groupPayment    = dialog.addGroup("Payment");
    fieldPaymTermId = dialog.addField(typeid(CustPaymTermId));
    fieldPaymMode   = dialog.addField(typeid(CustPaymMode));
    fieldPaymTermId.enabled(false);
    fieldPaymMode.enabled(false);
    return dialog;
}
public void dialogSelectCtrl()
{
    CustTable custTable;
    ;
    custTable   = CustTable::find(fieldAccount.value());
    fieldName.value(custTable.Name);
    fieldGroup.value(custTable.CustGroup);
    fieldCurrency.value(custTable.Currency);
    fieldPaymTermId.value(custTable.PaymTermId);
    fieldPaymMode.value(custTable.PaymMode);
}
static void main(Args _args)
{
    CustSelect custSelect = new CustSelect();
    ;
    if (CustSelect.prompt())
    {
        CustSelect.run();
    }
}
