Function called by relation event after taking a photo.


PUBLIC FUNCTION dlgEvent__action_action_AfterPhoto( 
   dlg ui.DIALOG, errNo INTEGER, errMsg STRING, photoPath STRING )

The action part of the function name is defined by the Action property of the relation (under Source UI Settings) . If the Action property is not set, an error will occur at compile time.

The function has four parameters:

  1. dlg. This is a ui.DIALOG object referencing the current dialog. The dialog can implement an INPUT, INPUT ARRAY, DISPLAY ARRAY, MENU, or CONSTRUCT. For more information, see The Dialog class in Genero Business Development Language User Guide.
  2. errNo. This is an SQLCA.SQLCODE error.
  3. errMsg. This is the SQLERRMESSAGE message.
  4. photoPath. This is the path where the photo is stored.


When you select the After Taking Photo property for the creation of the event, a function shell is created. Enter your code in the function.

This function is called when a photo is taken.

Example: After Taking Photo

This example uses the After Taking Photo code event on a relation. The Action property of the relation is set to takePhoto. Every time a user takes a photo, a message is displayed.

PUBLIC FUNCTION dlgEvent__action_takePhoto_AfterPhoto(dlg ui.Dialog, errNo INTEGER, errMsg STRING, photoPath STRING)

        DISPLAY "Photo saved to: " || photoPath 
        DISPLAY "ERROR: [" || errNo || "] " || errMsg
    END IF
