BUILDING APPLICATIONS WITH ACTIVEX When developing a standalone executable using ESRI ArcObjects, it is the responsibility of the application to check and configure the licensing options. A license can be configured either using the LicenseControl or using the coclass AoInitialize and the IAoInitialize interface it implements that are designed to support license configuration. License initialization must be performed at application start time, before any ArcObjects functionality is accessed. Failure to do so will result in application errors. For more information about licensing see the ‘Licensing and deployment’ chapter. The LicenseControl will appear on a form at design time so that it can be selected and its property pages viewed. However, at runtime the LicenseControl is invisible so its position on the form is irrelevant. LICENSE CONFIGURATION AND DEPLOYMENT To successfully deploy this application onto another machine, the application must configure a license. First, it must check that the product license is available, and second, it must initialize the license. If this license configuration fails, the application cannot run. License configuration can be performed either using the LicenseControl or programmatically using the AoInitialize object. For the purpose of this application, the LicenseControl will be used to handle license configuration. 1. Open the Visual Basic Form. 2. Double-click the LicenseControl button in the Visual Basic toolbox to add the LicenseControl to the form. This application can be initialized with an ArcGIS Engine license, but you may optionally initialize the application with a higher product license. For example, if you check 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 checked). If no product licenses are available, then the application will fail to initialize. In this application the LicenseControl will handle license initialization failure. If the application cannot be initialized with an ‘ArcGIS Engine’ product license, a License Failure dialog box will be displayed to the user before the application is automatically shut down. Alternatively, a developer can handle license initialization failure using the ILicenseControl interface members to obtain information on the nature of the failure before the application is programmatically shut down. 3. Right-click on LicenseControl and click Properties to open the LicenseControl property pages. 4. Check the ArcGIS Engine product license and check ‘Shutdown this application if the selected licenses are not available’. Click OK. 5. Compile the application into an executable. 302 • ArcGIS Engine Developer Guide
BUILDING APPLICATIONS WITH ACTIVEX To successfully deploy this application onto a user’s machine: • The application’s executable and the DLL containing the custom command will need to be deployed onto the user’s machine. • The user’s machine will need an installation of the ArcGIS Engine Runtime and a standard ArcGIS Engine license. ADDITIONAL RESOURCES The following resources may help you understand and apply the concepts and techniques presented in this scenario. • Additional documentation available in the ArcGIS Engine Developer Kit including ArcGIS Developer Help, component help, object model diagrams, and samples to help you get started. • ArcGIS Developer Online—Web site providing the most up-to-date information for ArcGIS Developers including updated samples and technical documents. Go to http://arcgisdeveloperonline.esri.com. • ESRI online discussion forums—Web sites providing invaluable assistance from other ArcGIS developers. Go to http://support.esri.com and click the User Forums tab. • Microsoft documentation on the Visual Basic 6 development environment. Chapter 6 • Developer scenarios • 303
