Lesson 7.2. Automatic management of errors
This lesson will teach you the following concepts
  • What is the automatic management of errors?
  • Using the automatic management of errors.
Lesson duration

Estimated time: 10 mn
Previous LessonTable of contentsNext Lesson
Overview
The errors can be automatically managed by WINDEV. This feature helps you reduce the number of code lines while centralizing the management of errors.
The use of this feature also makes the code easier to read.

Operating mode

Two operations are performed when an error is detected by a WLanguage function:
  • an error value is returned by the function (for example, fOpen returns "-1" if the specified file was not opened).
  • WLanguage detects the error (the ErrorOccurred variable is set to True), and its details can be retrieved using ErrorInfo.
This second operation can be automatically managed by the error management of WINDEV.

Implementation

The automatic management of errors can be configured:
  • in the code editor: all you have to do is click the link "If error: By program" in the code editor:
    Configuring the automatic error management
  • by programming with ErrorChangeParameter.

Types of affected errors

Two types of errors can occur in WLanguage:
  • the "non-fatal" errors (also called runtime errors): in most cases, these errors are managed in the code and they do not stop the application. For example, opening a file that cannot be accessed or an archive that does not exist.
  • the "fatal" errors (also called programming errors): in most cases, these errors are linked to a development problem (access to a non-declared file, use of non-existing controls ...). A "fatal" error can also occur after a "non-fatal" error that was not processed properly. In this case, the application will be stopped.
The mechanism for managing errors is used to manage these two types of errors according to different methods in order to specify behaviors adapted to the errors that occur.
Automatic management of errors: a training example
  • To understand the different error cases, we will be using a training example supplied with WINDEV.
    1. Display the WINDEV home page if necessary (Ctrl + <).
    2. On the home page, click "Open an example". The list of complete examples, training examples and unit examples supplied with WINDEV is displayed.
    3. Type "Error" in the search area. Only the examples containing this word are listed.
      Examples from the home page
    4. Select the "WD Auto Error Management" project. The project is loaded.
  • This project presents the management:
    • of a non-fatal error (opening an archive that does not exist).
    • of a fatal error (division by 0).
    • of an error on several levels.
  • Run the project test by clicking Run project test (among the quick access buttons).
    1. Click "Managing a non-fatal error".
    2. The following window is displayed.
      Management of a non-fatal error
    3. Click the "Test this error management" button.
    4. When running the code line that triggers the error, an error message is displayed, allowing the user to retry the operation, cancel the operation or stop the application. The "Debug" option should be used:
      • in test mode, to directly debug the application.
      • in executable mode, to debug an executable directly from WINDEV.
    5. Click "Cancel the operation" and close the window.
  • Click "Managing a fatal error".
    1. The following window is displayed. This window is used to check the error when an integer is divided by 0.
      Management of a fatal error
    2. Click the "Test this error management" button.
    3. When running the code line that triggers the error, a procedure is automatically called. This procedure is used to display the error message and to stop the current process.
    4. Click "OK" and close the window.
  • Click "Managing an error on several levels".
    1. The following window is displayed. This window is used to test an error on several levels (process calling a procedure that opens an archive that does not exist).
      Management of an error on various levels
    2. Click the "Test this error management" button.
    3. When running the code line that triggers the error:
      • the procedure returns "False" to the calling process.
      • the calling process displays an error message and stops the process.
    4. Click the "Cancel the operation" button.
  • Stop the application test.

Example

WINDEV also proposes an automatic management of HFSQL errors. See the "Detecting HFSQL errors" training example (supplied with WINDEV) for more details. This example is accessible from the WINDEV home page.

Lesson 7.1. Overview
This lesson will teach you the following concepts
  • Overview.
  • How to open a training example?
  • How to open a unit example?
Lesson duration

Estimated time: 5 mn
Previous LessonTable of contentsNext Lesson
Overview
This section presents several advanced features. You don't necessarily have to read it but it will allow you to discover some advanced features proposed by WINDEV.
The different lessons found in this section are based on examples supplied with WINDEV.
WINDEV proposes different types of examples:
  • complete examples: these examples correspond to a full application that is using one or more features.
  • training examples: these examples correspond to a small application used to discover a feature.
  • unit examples: these examples correspond to a window used to quickly check the use of function.

Practical example

To simplify the presentation of different features, we will be using unit examples or training examples supplied with WINDEV.
  • To open a complete example, a training example or a unit example from the WINDEV home page:
    1. Display the home page (Ctrl + <).
    2. On the home page, click "Open an example". The list of complete examples, training examples and unit examples supplied with WINDEV is displayed. These examples are grouped by type of example (complete, training, ...).
    3. You can enter a keyword in the search area (for example, enter "Errors"). Only the examples containing this word are listed.
      Examples in the home page
      The icons to the right of the example name indicate the platform for which the example has been created.
      Remark: The buttons to the right of the search area allow you to filter the examples according to the desired platform(s).
    4. To open an example, double-click the example name.
    5. For the complete and training examples, the current project is automatically closed and the sample project is opened.
    6. For the unit examples, the associated window is opened in the current project.
Remark: If you modify a full example or a training example, the next time you open it, WINDEV will automatically ask you which version of the example you want to work on:
  • your modified version. In this case, you will find all your modifications.
  • the original version of the example: In this case, the modified version is deleted and you get all the features of the original example.
