Syntax

Syntax of new User Groupware Hide the details

<Result> = gpwOpen([<Directory of groupware files>])

<Result>: Integer constant

Result regarding the opening of login window/page.
gpwCancel The user clicked the "Cancel" button found in the login window of Groupware.
gpwError An error occurred. For more details, use ErrorInfo.
gpwInvalidPassword The password is not valid. It does not correspond to the user password described in the groupware database.
gpwOk The user is connected.
gpwUnknownUser The user is not referenced in the database of user groupware.

<Directory of groupware files>: Optional character string

These data files are used to manage the 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_<Project name>.

If this parameter corresponds to an empty string ("") or if it is not specified, the default directory of the user groupware will be used.
If this parameter corresponds to a dot ("."), the data files of user groupware will be created on the server at the root of 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 <Procedure name>(<Connection> is boolean)

The <Connection> is a boolean:
True if the user is connected,
False if the user is not connected.

<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 GO mode (Go simulator or Go on phone with WMDev), the test database will be used as the database of users and rights.
if the application is launched from the version deployed on the mobile device, or an Android emulator, the production database will be used as the database of users and rights.
gpwDatabaseProduction Forces the use of the user and production rights database regardless of the application start mode.
gpwDatabaseTest Forces the use of the user and test rights database regardless of the application start mode.

Syntax of the former User Groupware (kept for backward compatibility) Hide the details

<Result> = gpwOpen([<Directory of rights file> [, <User files directory>]])

<Result>: Integer constant

Result regarding the opening of login window/page.
gpwCancel The user clicked the "Cancel" button found in the login window of Groupware.

<Directory of rights file>: Optional character string

These data files are used to manage the rights granted to the users for the different windows of the application. These files are specific to the application. 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_<Project name>.

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

<User files directory>: Optional character string

These data files can be common to several applications. By default, these data files are created in a subdirectory of your project (EXE\GPW_<Project name> directory). You can define the location of the User Groupware files common to several applications. In this case, you must specify the path of data files to use.
By default, these data files are created on the server in a subdirectory of your database: directory .\GPW_<Project name>.

Remarks

How to use gpwOpen?

gpwOpen allows you to define the User Groupware startup mode. This allows you to perform other actions before opening the User Groupware login window or page: execute code, open windows or pages, etc.

Usage example of this function: in a multilingual application that is using the User Groupware, the first window or page of the application is used to choose the runtime language. When creating the application, you must:

choose not to automatically run the User Groupware during its integration
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 run" mode, the following operations must performed:

Do not define a first project window.
Call gpwOpen in the "Initializing" 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 "Initializing the project after connection to the site" event.
