<Result> = gpwOpen([<Groupware files directory>])

<Result>: Integer constant

Result when the login window/page opens.
gpwCancel The user clicked the "Cancel" button in the Groupware login window.
gpwError An error occurred. For more details, use the ErrorInfo function.

gpwUnknownUser The user is not listed in the User Groupware database.

<Groupware files directory>: Optional character string

These data files are used to manage users and their rights. By default, these data files are created in a subdirectory of your project (EXE\GPW_<Project name> directory).
By default, these data files are created on the server in a subdirectory of your database: directory .\GPW_ DIRECTORY<Nom du projet>.

If this parameter is an empty string ("") or is not specified, the default directory of the User Groupware will be used.
If this parameter is a dot ("."), the User Groupware data files will be created on the server at the root of the database.

Specific syntax for Android and iOS applications Hide the details

gpwOpen(<WLanguage procedure> [, <User database>])

<WLanguage procedure>: Procedure name

Name of the WLanguage procedure ("callback") called when the login window is closed.
This procedure has the following format:
PROCEDURE <Nom de la procédure> (<Connexion> est un booléen)
The <Connection> is a boolean:
True if the user is logged in,
False if the user is not logged in.

<User database>: Integer constant

Database of users and rights to use:
gpwDatabaseDefault The database of users and rights depends on the application start mode:
if the application is launched in test mode (via the simulator or directly on the device with WMDev), the test database will be used.
if the application is launched from the version deployed on the mobile device, or an Android emulator, the production database will be used.
gpwDatabaseProduction Forces the use of the production database regardless of the application start mode.
gpwDatabaseTest Forces the use of the test database regardless of the application start mode.

Remarks

How to use the gpwOpen function?

gpwOpen allows you to define the User Groupware startup mode. This enables you to perform a number of actions before launching the user Groupware connection window or page: execute code, launch windows or pages, etc.

An example of how to use this function: in a multilingual application using user Groupware, the first window/page of the application lets you choose the runtime language. When creating the application, you must:

choose not to automatically start the User Groupware when it is integrated
open the window or page for language selection as first application window, then call the login window or page with gpwOpen.

If the User Groupware is enabled in "Manual start" mode, the following operations must be performed:

Do not define a first project window.
Call gpwOpen in the "Initialization" event of the project.
Open the first project window from the WLanguage code of the procedure passed as a parameter to gpwOpen.

Pre-launched sessions

If your project uses pre-launched sessions, this function must not be used in the project initialization event. This function must be used in the "Initialization in pre-launched session mode" event.
