1. Creating the "RAD Pattern" project.
2. Creating the different pattern windows.
   • Form window (with link buttons if necessary).
   • Table window (with link buttons if necessary).
   • Relation window (with link buttons if necessary).
   • Vision Plus buttons and window.
   • 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 relation window RADFileB/RADFileD.

Standard to follow

Overview

• select an element of RADFileA from a form on RADFileB.
• select an element of RADFileB from a form on RADFileC.

• in the form window: a combo box and a button.
• a Vision Plus window.

Creating the Vision Plus window

• a table.
• buttons used to select and handle the elements in the table.

1. Click in the quick access buttons:
   • The creation window appears: click "Window" then "Window".
   • The window creation wizard starts.
   • In the wizard, select "Blank" and validate.
2. In the description window, enter the following information:
   • The window name. This name must necessarily contain the name of the file displayed in the table (some examples: WIN_Vision_RADFileA, WIN_Vis_RADFileA, ...).
   • The window title. If the title must display the name of the file, use the name of the "RADFileXX" file (for example, "RADFileA: Vision plus").
3. Save the window.
4. Create a Table control in the window: on the "Creation" tab, in the "Data" group, expand "Table and List Box" and select "Table (Vertical)".
5. In the table creation wizard, specify the following characteristics:
   • Select "Display data from a file or existing query".
   • Select the base file of the table (RADFileA for example).
   • Keep the proposed item as well as the search item.
   • Specify the source for the fill operation: "File with direct access".
   • Validate the name of the table.
6. Position the Table control in the window and define its size.
7. Create and position the different buttons of your window: OK, Cancel and New.
   Caution: if the user is allowed to apply a skin template to the windows created by RAD, you must define the type of button that must be used in the skin template. This information can be defined in the modifier ("Skin template" category).
8. Case of the OK button.
   This button will be used to validate the selection in the table. The code of the OK button is as follows:
   
   // Return value
   MyWindow..ReturnedValue = True
   
   
   This button is associated with the preset action "Close the window and return a value", the value being specified in the code by ReturnedValue.
9. Case of Cancel button
   This button is used to cancel the selection. This button is associated with the preset action "Close the window and return a value", the value being specified in the code by ReturnedValue.
10. Case of New button
    This button is used to create a new record by opening the corresponding form window. The code of the New button can be:
    
    // Reset the record of RADFileA
    HReset(RADFileA)
    // Open the form of RADFileA
    IF Open(WIN_Form_RADFileA) THEN
    // Refresh the table
    TableDisplay(TABLE_RADFileA, taCurrentFirst)
    END
    
11. Initialization code of window:
    
    // Position on the current record
    TableDisplay(TABLE_RADFileA, taCurrentFirst)
    // Default return value
    MyWindow.ReturnedValue = False
    

Creating the necessary elements in the form window

• Form on RADFileB
• Form on RADFileC
• Relation window with form on RADFileB

1. On the "Creation" tab, in the "Usual controls" group, click "Combo Box". The Combo Box control creation wizard starts.
2. In the combo box creation wizard, select the following options:
   • "I want to enter a list of values or populate the combo box programmatically".
   • the combo box is linked to no item
   • the expanded control is a list
   • the name of the control is "COMBO_IDRADFileX" (COMBO_ is the prefix defined in the code style: it is not required if no code style is used). For example, for the RADFileB form, the combo box will be named COMBO_IDRADFileA.
3. Validate. The Combo Box control is created.

1. On the "Creation" tab, in the "Usual controls" group, click "Button".
2. In the control description window, specify the name of the button. This control has a name in the following format: "BTN_VISION_RADFileX" (BTN_ is the prefix defined in the code style: it is not required if no code style is used). For example, for the RADFileB form, the button will be named BTN_VISION_RADFileA.
   Caution: if the user is allowed to apply a skin template to the windows created by RAD, you must define the type of button that must be used in the skin template. This information can be defined in the modifier ("Skin template" category).
3. The click code of the button is as follows:
   
   // Open the vision window of RADFileA
   IF Open(WIN_Vision_RADFileA) = True THEN
   // Refreshes the content of the RADFileA combo box
   ListDisplay(COMBO_IDRADFileA, taCurrentFirst)
   END
