1. Creating the "RAD Pattern" project.
2. Creating the different pages of the pattern.
   • Form pages.
   • Table page.
   • Relation page.
   • Buttons and Vision Plus page.
   • Menus.
3. Generating the RAD pattern.
4. Using the RAD pattern.

The files to create

• A form for RADFileA.
• A form for RADFileB. A Vision Plus button (or a popup combo box) must allow you to select an element of RADFileA.
• A form for RADFileC. A Vision Plus button (or a popup combo box) must allow you to select an element of RADFileB.
• A table for RADFileA.
• A table for RADFileB.
• A table for RADFileC.
• A RADFileB/RADFileD relation page.

Standard to follow

Overview

• A supercontrol: This supercontrol contains the controls of the form to display. This supercontrol is linked to the file to display.
• Buttons used to validate or to cancel (back button).
• Vision Plus buttons used to select elements of another file in a specific page (for the forms regarding RADFileB and RADFileC only).

Example of Form page for the Intranet pattern:

To create a form page:

1. Click in the quick access buttons.
   • The window for creating a new element is displayed: click "Page" then "Page".
   • The page creation wizard opens.
   • Select "Blank". You can select the template used in your pattern.
2. In the description window, enter the name of the page. This name must contain the name of the file displayed in the file (examples: PAGE_Fiche_RADFichierA, PAGE_Fic_RADFichierA, ...)..
   Note: If you want to specify the name of the current file to the user, use the name of the file (RADFileA for instance) in a caption. The RADFileX term will be automatically replaced with the caption of the file described in the analysis.
3. Save the page.
4. Create a supercontrol on the page: under the "Creation" pane, in the "Containers" group, click on "Supercontrol".. This supercontrol will display the controls found in the form. Position this control in the page and define its size. Scrollbars will be automatically displayed if some of the controls cannot fit in the specified size.
5. In the supercontrol description window, specify the name of the supercontrol. This name must be SC_Fiche (SC_ is the prefix of the programming guidelines: it is not necessary if you are not using programming guidelines).
6. In the "Content" tab of the supercontrol description window, specify:
   • the data file browsed: RADFichierXX (e.g. "RADFichierA").
   • the item browsed: IDRADFileXX ("RADFileAID" for example).
7. Create and position the various buttons on your page: validation button, back to previous page button, etc. These buttons can have any name.
8. Case of validation button ("OK" or "Validate" button for example).
   In the validation button code, it is advisable to activate automatic error handling (Option "If Error: ", with automatic processing "Execute error handling ("ERROR CASE:" in code)").
   The code of the validation button can be (for a form on RADFileA):
   

   // Read the information entered 
   PageToFile()
   // If it's a new record
   IF RADFileA..NewRecord = True THEN 
   	// Add it
   	HAdd(RADFileA) 
   ELSE 
   	// Modify it 
   	HModify(RADFileA) 
   END
   // Back to the previous page
   IF PreviousPage() = "" THEN
   	PageDisplay(PreviousPage)
   ELSE
   	PageDisplay(PAGE_Home)
   END
   
   CASE ERROR:
   	Error("An error occurred during the validation.", HErrorInfo())
   	RETURN

9. Case of return button ("Back" button for example).
   

   // Are we coming from a page?
   IF PreviousPage() = "" THEN
   	// Yes, display this page
   	PageDisplay(PreviousPage())
   ELSE
   	// No, go back to the home page
   	PageDisplay(PAGE_Home) 
   END

   
   Remark: This code requires the presence of a page named "PAGE_Home" in the RAD pattern.. This page can be the home page of the site and it can contain the main menu of the site. For more details, see Menu page.
10. Enter the initialization code of the page. Example:
    

    // Display the records 
    FileToPage()

    
    This code is used to display the value of the records in the form.
11. Add the Vision Plus buttons if necessary (for the RADFileB and RADFileC forms).

Case of print buttons

• The name of these reports must contain RADFileX. For better readability, we recommend that you use "Form" or "Table" in the name of the form to easily identify the type of the report.
• This name must be used in the code of the print button:
  

  // Create a unique file name
  sFile is string = fDataDir() + "\" + DateSys() + TimeSys() + ".pdf"
  // Print the report in a PDF file
  iDestination(iPDF, sFile)
  // Generate the report
  iPrintReport(RPT_List_RADFileA)
  // Display the report in PDF format
  FileDisplay(sFile, "application/pdf")
  // Delete the file
  fDelete(sFile)
