ESRI LicenseControl

Description

Use the LicenseControl to initialize each application with a suitable license(s) in order for it to run successfully on any machine it is deployed on to. The LicenseControl will configure the licenses at application start time when the form or dialog containing the LicenseControl is loaded.

All applications need to be configured with a license except when the application is not a stand-alone executable i.e. if it's a dll that will be incorporated into an application that will itself perform the license configuration.

There are two types of license to consider when initializing an application, product licenses and extension licenses if an application uses any of the ArcGIS extensions. These licenses can be Engine Single Use, Desktop Single Use or Desktop Concurrent licenses.

• Engine Single Use provides access to either the ArcGIS Engine or ArcGIS Engine Enterprise GeoDatabase licenses.
• Desktop Concurrent licenses provide access to the Desktop concurrent ArcView, ArcEditor and ArcInfo licenses.
• Desktop Single Use licenses use the same technology as Desktop Concurrent licenses and provide access to Single Use ArcView, ArcEditor and ArcInfo licenses. The LicenseControl does not differentiate between a Single Use and a Desktop Concurrent license so they should be treated as the same.

Once an application has been initialized with a license it cannot be re-initialized (with a new license); an application is initialized with a license for the duration of its life. When initializing an application with a license the following must be considered:

• The types of product license that the application can run with. For example, an enterprise geodatabase editing application will not be able to run with an ArcGIS Engine license or an ArcView license. However, it will be able to run with an ArcGIS Engine Enterprise GeoDatabase license, an ArcEditor license or an ArcInfo license.
• The types of product license available to the application. For example, an application that can be run with an ArcGIS Engine license will also run with an ArcView, ArcEditor and an ArcInfo license. However, it may not be desirable to consume more than the minimum required license as doing so would lock the license for the lifetime of the application.
• Using an ArcView license on an ArcGIS Engine application will give you access to all the functionality available to a standard Engine license. Likewise, using an ArcEditor license on an ArcGIS Engine application will give you access to all the functionality available to an ArcGIS Engine Enterprise GeoDatabase license.

Use the LicenseControl to automatically perform license initialization within simple graphical user interface applications using the ArcGIS MapControl, PageLayoutControl, TOCControl, ToolbarControl, SymbologyControl, SceneControl or GlobeControl. If greater control is required over license initialization, particularly when checking out and in extension licenses (the LicenseControl will check out extension licenses for the duration of an application's life) use the AoInitialize object to programmatically perform license initialization.

Using the LicenseControl in an application that programmatically initializes a product license is not recommended, because the LicenseControl may initialize a product license before the initialization code executes. However, the LicenseControl can be used to initialize an application with a product license, and any required extension licenses can be checked out and in programmatically.

Use the License Property Page to select the product licenses the application can be initialized with, select the extension licenses required by the application and to set whether the application is shutdown automatically if license initialization fails.

Products

Select at least one product license the application can be initialized with. By default the LicenseControl will try to initialize the application with the ArcGIS Engine product license.

If the product you require is not licensed you may optionally initialize the application with a higher product license. For example, if you select the ArcGIS Engine license and the ArcView license, the LicenseControl will initially try to initialize the application with an ArcGIS Engine license (the lower license). If that license is not available the LicenseControl will try to initialize the application with an ArcView license (the next higher level license selected). If no product licenses are available then the application will fail to initialize. Note, that once an application is initialized with a product license it is not possible to re-initialize the application for the duration of the applications life.

Extensions

Select the extension licenses required by the application. Not every extension license is available with every product license, as such the list of available extension licenses will change as different product licenses become selected. If the ArcGIS Engine product license is selected and an ArcGIS Desktop product is selected, only the ArcGIS Engine extension licenses will display.

The availability of each extension license is checked in conjunction with the product license that the application will ultimately be initialized with. If any of the selected extensions are not available the application will fail to initialize. The LicenseControl will check out extensions directly after the application is initialized and will check in extensions when the application is shutdown.

If a SceneControl or GlobeControl (requiring the 3D Analyst extension) is embedded within the same container as the LicenseControl, the 3D Analyst extension will automatically be checked.

Shutdown

Set whether the LicenseControl will automatically shut down the application if license initialization fails. If the LicenseControl handles license initialization failure a 'License Failure' dialog box will be displayed to the user before the application is shutdown. If the developer handles license initialization failure the ILicenseControl interface members can be used to obtain information on the nature of the failure before the application is programmatically shut down.

The status of the LicenseControl initialization.

Description

Returns the Status of the LicenseControl when it initially tried to initilaize the application. If license initailization was successful the Status will return esriLicenseCheckedOut.

Remarks

If no product licenses were checked in the LicenseControl property pages, the Status returns esriLicenseFailure.

A summary of the status of the LicenseControl initialization.

Description

Returns a summary of the license status after the LicenseControl has tried to initialize the application with a license. Use the Summary property when license initialization fails, to give information to the user on the nature of the failure, before programmatically shutting down the application.

The possible descriptions returned from the Summary property are as follows:
- "Successful license initialization."
- "No licenses were requested."
- "Failed to initialize license, required products are not available."
- "Failed to initialize license, required extensions are not available."
- "Failed to initialize product license."
- "Failed to checkout extension license."

Remarks

The default behaviour of the LicenseControl is to allow the developer to programmatically check for and shutdown an application when license initialization fails. To override this behaviour so the LicenseControl automatically shuts down an application when license initialization fails, check the "Shutdown this application if the selected licenses are not available" check box in the property pages of the LicenseControl.

                             AutomationException

Shows a dialog displaying the LicenseControl status and the current license availability.

Description

Opens a modal dialog specifying the current availability of the specified product and extension licenses. Use the ShowStatusDialog method when license initialization fails, to give information to the user on the nature of the failure, before programmatically shutting down the application. Alternatively, use the Status, Summary and LicenseAvailability members to create your own dialog.

esriLicenseStatusRequested returns the availability of those product and extension licenses checked in the LicenseControl property pages. Use this option when license initialization fails, to give information to the user on the nature of the failure, before programmatically shutting down the application.

esriLicenseStatusAll returns the availability of all product and extension licenses. Use this option when debugging.

By default the modal dialog will have a window title of "License Status" and a heading of "Requested License Status".

Remarks

The default behaviour of the LicenseControl is to allow the developer to programmatically check for and shutdown an application when license initialization fails. To override this behaviour so the LicenseControl automatically shuts down an application when license initialization fails, check the "Shutdown this application if the selected licenses are not available" check box in the property pages of the LicenseControl.
