Adds a row at the end of a Looper control.
Warning
It is recommended to use <Looper>.AddLine. <Looper>.AddLine allows you to add:
  • TAB characters into the attributes/controls.
  • all types of values into the attributes/controls.
Example
// Initialize the Looper control named LOOP_LOOPER1
LOOP_LOOPER1.DeleteAll()
HReadFirst(Product, ProdName)
WHILE HOut() = False
LOOP_LOOPER1.Add(Product.ProdName + TAB + Product.ProductCode)
HReadNext(Product, ProdName)
END
// Add an empty row
LOOP_Looper1.Add()
// Position on the empty row
Index = LOOP_Looper1.Count()
// Then, initialize the attributes
ATT_AttributeLastName[Index] = "Hobbes"
ATT_AttributeFirstName[Index] = "Samantha"
 
// Or initialize the controls
// LOOP_Looper1[Index].ControlLastName = "Hobbes"
// LOOP_Looper1[Index].ControlFirstName = "Samantha"
Syntax

Adding a row to a Looper control with attributes Hide the details

<Result> = <Looper control>.Add([<Value>])
<Result>: Boolean
  • True if the addition was successful,
  • False otherwise.
<Looper control>: Control name
Name of the Looper control to be used.
<Value>: Optional character string
List of values that will be inserted into the new row. This parameter must have the following format:
<Value 1> + TAB + ... + <Value N>

The different values must be specified in the order of the attributes (Looper control description window).
To specify no value for one of the attributes, use an empty string ("") or 0 (depending on the type of attribute).
An empty row will be added if this parameter corresponds to an empty string ("").

Adding a row to a Looper control without attributes Hide the details

<Result> = <Looper control>.Add()
<Result>: Boolean
  • True if the addition was successful,
  • False otherwise.
<Looper control>: Control name
Name of the Looper control to be used.
Remarks

Use conditions

<Looper>.Add can be used on:
  • a Looper control based on a data file,
  • a Looper control populated programmatically.

Adding an empty row

After adding an empty row, each attribute or control must be initialized individually.
For example:
  • For a Looper control with attributes:
    // Add an empty row
    LOOP_Looper1.Add()
     
    // Position on the empty row
    Index = LOOP_Looper1.Count()
    // Then, initialize the attributes
    ATT_AttributeLastName[Index] = "Hobbes"
    ATT_AttributeFirstName[Index] = "Samantha"
    ATT_ColorAttributeFirstName[Index] = LightRed
    ATT_AttributeAddressVisible[Index] = False
  • For a Looper control without attributes:
    // Add an empty row
    LOOP_Looper1.Add()
     
    // Position on the empty row
    Index = LOOP_Looper1.Count()
    // Then, initialize the controls
    LOOP_Looper1[Index].ControlLastName = "Hobbes"
    LOOP_Looper1[Index].ControlFirstName = "Samantha"
    LOOP_Looper1[Index].ControlFirstName.BackgroundColor = LightRed
    LOOP_Looper1[Index].ControlAddress.Visible = False

Characteristics of the row

If a value corresponds to the result of a calculation, the numeric expression must be enclosed in brackets. For example:
LOOP_CalclulationZone.Add((53+29) + TAB + (83-21))

Position of the new row

By default, the row is added at the end of the Looper control.
If the Looper control is sorted (<Looper>.Sort), the added row is positioned in the Looper control according to the current sort.

Handling a binary memo

To add a binary memo into a Looper control, use <Looper>.AddLine.
