Method and apparatus for launching computer applications
View Patent ↗Method and apparatus for launching applications on a computer. A launcher allows a user to quickly determine which applications are installed and to start one or more selected applications. The launcher accesses an operating system registry to determine which applications are installed and where each application is installed. The launcher presents information in a file formatted using a scripted language such as hypertext markup language (HTML), so that the file can be read by a standard web browser application, such as the well-known Netscape Navigator™ or Microsoft Internet Explorer™. Thus, a user is presented with a standard graphical user interface that he or she most likely knows. The user makes the selection by clicking with his or her mouse. The display may simply list the installed applications, or it may list all known applications, showing unavailable applications with a different visual attribute than installed applications, for example, dimmed or grayed out text. When the user selects an application, the launcher determines the location of the selected application from tags in the HTML file and launches the selected application, suppressing any browser dialog boxes normally associated with remotely starting applications by preventing the browser from navigating to the selected application.
1. A method of launching a selected application on a computer, the method comprising the steps of:
accessing the operating system registry to determine which applications are installed and where each application is installed;
creating a hypertext markup language (HTML) file specifying the applications that are installed;
displaying the HTML file in a browser so that a user can select any one of the applications that is installed as a selected application to launch; and
if the user selects an application as the selected application, determining the location of the selected application from tags in the HTML file and launching the selected application without allowing the browser to navigate to the application.
2. The method of claim 1 wherein the HTML file lists applications that are known but not installed and the file is displayed in the displaying step so as to show applications that are known but not installed with a specific visual attribute.
3. A computer program product for launching a selected application on a computer, the computer program product including a medium having a computer program embodied thereon, said program comprising:
instructions for accessing the operating system registry to determine which applications are installed and where each application is installed;
instructions for creating a hypertext markup language (HTML) file specifying the applications that are installed;
instructions for displaying the HTML file in a browser so that a user can select any one of the applications that is installed as a selected application to launch; and
instructions for determining if an when a user as selected an application as the selected application, and determining the location of the selected application from tags in the HTML file and launching the selected application without allowing the browser to navigate to the selected application.
4. The computer program product of claim 3 wherein the HTML file lists applications that are known but not installed and the file is displayed by the instructions for displaying so as to show applications that are known but not installed with a specific visual attribute.
5. Apparatus for launching a selected application on a computer, the apparatus comprising:
means for accessing the operating system registry to determine which applications are installed and where each application is installed;
means for creating a hypertext markup language (HTML) file specifying the applications that are installed;
means for displaying the HTML file in a browser so that a user can select any one of the applications that is installed as a selected application to launch; and
means for determining if an when a user as selected an application as the selected application, and determining the location of the selected application from tags in the HTML file and launching the selected application without allowing the browser to navigate to the application.
6. A programmed computer system, the programmed computer system operable to launch a selected application on a computer by performing the steps of:
accessing the operating system registry to determine which applications are installed and where each application is installed;
creating a hypertext markup language (HTML) file specifying the applications that are installed;
displaying the HTML file in a browser so that a user can select any one of the applications that is installed as a selected application to launch; and
if the user selects an application as the selected application, determining the location of the selected application from tags in the HTML file and launching the selected application without allowing the browser to navigate to the application.
7. The computer system of claim 6 wherein the HTML file lists applications that are known but not installed and the file is displayed in the displaying step so as to show applications that are known but not installed with a specific visual attribute.
