Stored procedures
Changes the values of the attributes in a row of a Looper control.
Remark: It is recommended to use <Looper>.ModifyLine. Indeed, <Looper>.ModifyLine allows you to insert:
  • TAB characters into the attributes/controls.
  • all types of values into the attributes/controls.
WINDEVReports and QueriesUniversal Windows 10 AppAndroidiPhone/iPadJavaUser code (UMC) For Looper controls without attributes, it is recommended to directly change the value of the relevant controls. For more details, see "Modifying a Looper control without attributes.
Example
// Modify a row in a Looper control
LOOP_Looper1.Modify(ProductName + TAB + ProductCode, Index)
// Modifies a value in the Looper control at position 12
LOOP_Looper1.Modify(LastName + TAB + FirstName + TAB + ...
PhoneNum + TAB + FaxNum, 12)
Syntax
<Looper control>.Modify(<Value> [, <Index>])
<Looper control>: Control name
Name of the Looper control to be used.
<Value>: Character string
List of modified values. 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 an attribute, use an empty string ("") or 0 (depending on the type of the attribute).
<Index>: Optional integer
Index of the row to be modified.
  • If this parameter is not specified, the modification will be performed on the current element.
  • If <Index> is greater than the number of rows, <Looper>.Modify is equivalent to <Looper>.Add.
