Stored procedures
Overview
Two types of procedures are available:
  • Global procedure: can be used in all the processes/events of the project. This global procedure is stored in the project.
  • Local procedure: can be used in all processes/events that depend on the object (window, page or report) in which this procedure was declared. This local procedure is stored in the object.
Important: You must not declare two procedures with the same name (especially a global procedure and a local procedure).
Reminder:
  • In WLanguage, there is no distinction between the procedures and the functions. The syntaxes for declaring and using procedures also apply to functions.
  • Versions 16 and later
    You have the ability to create overloaded procedures. See Prototype overload for more details.

WINDEVUniversal Windows 10 AppJava

Procedures local to a window

The local procedures declared in a window can be called from all processes/events:
  • of the window,
  • of the window controls,
  • of the local procedures associated with the window.
These procedures are stored in the window.
Limits:
  • The local procedures of a window cannot be used by its sibling windows.

Remark: To transform a section of code already entered in a local procedure into a local procedure:
  1. Select the corresponding code.
  2. Select "New .. Create a local procedure containing the selected code" from the popup menu.
  3. Specify:
  4. The procedure is created, the corresponding code is replaced by the call to the procedure with the necessary parameters.

Creation from the "Project explorer" pane

  1. Select the element associated with the local procedure (window, page, report, ...).
  2. Expand the element options and select "Local procedures".
  3. Display the popup menu.

To delete a local procedure from the "Project explorer" pane:
  1. Select the element associated with the local procedure (window, page, report, ...).
  2. Expand the element options.
  3. Expand the "Local procedures" option of the element.
  4. Select the desired procedure.
  5. Display the popup menu of the procedure and select "Delete".
Public or private local procedure
A local procedure is public by default: it is accessible from any code.
In some cases, it may be useful to restrict the access to a local procedure by making it "Private".
Versions 19 and later
When creating a local procedure, you have the ability to specify whether the procedure is public or private.
New in version 19

Remark: External component and private or public local procedures:
The use of private or public local procedures has an impact in the external components. Indeed, only the procedures explicitly declared as public (with the PUBLIC keyword used in their prototype) found in an external component cannot be accessed from the project that includes this component.
