CA 2333613

Controlling the usage of a software component (16) by an application program (12) in an end user computer system (10) includes obtaining an identifier of the application program by a controller computer system (24) and generating a first password from the received application program identifier and an identifier of the component. The component, the component's identifier and the first password are communicated to the end user computer system. The component is registered with the application as a "snap-in" or "plug-in" component. The application program generates a second password from the application program identifier and the received component identifier, compares the first password and the second password, and allows use of the "snap-in" component by the application program on to end user computer system when the first password matches the second password.

L'invention concerne la commande de l'utilisation d'un composant logiciel (16) par un programme d'application (12) dans un système informatique individuel (10), grâce à l'obtention d'un identificateur du programme d'application par un système informatique de commande (24) et la génération d'un premier mot de passe à partir de l'identificateur de programme d'application reçu et d'un identificateur du composant. Le composant, l'identificateur de composant et le premier mot de passe sont communiqués au système informatique individuel. Le composant est enregistré avec le programme d'application comme composant "insérable" ou "enfichable". Le programme d'application génère un deuxième mot de passe à partir de l'identificateur de programme d'application et de l'identificateur de composant reçu, compare le premier mot de passe au deuxième mot de passe, et autorise l'utilisation du composant "inséré" par le programme d'application dans le système informatique individuel lorsque le premier mot de passe correspond au deuxième mot de passe.
