Abstract

A method for automatically registering resources required for an application program module to execute. After the application program module is booted, a registration cache, which is stored in association with the application program module, is examined to determine its status. It indicates whether a registry on the computer system needs to be updated, e.g., after the user has moved files or renamed files. If so, a search is made through a predetermined directory to look for an application file or a dynamic link library file. If either is found, a resource fork in association with the file is opened, and it is determined whether there is a self-registration resource or an Object Linking and Embedded (OLE) Type Library (OTLB) in the resource fork. If found, any self-registration resource is registered by initiating a self-registration dynamic link library, and any OTLB resource is registered by initiating an OLE call.

Claims

1. A method for automatically updating a portion of a system registry of a computing device based upon an occurrence of a predefined event that affects the proper functioning of an application program module in the computing device, comprising the steps of:

building a portion of self-registration data into a resource fork of the application program module, the self-registration data being automatically updatable to be in sync with one or more corresponding linking files of the application program, the self-registration data being part of the resource fork of the application program module such that explicit calls to separate self-registration files are avoided;

determining that the predefined event that affects the proper functioning of the application program module in the computing device has occurred; and

if so,

determining whether the portion of the system registry of the computing device needs to be updated because at least one of the following conditions exists;

any information in a registration cache has changed; and

a registration cache does not exist; and

if so,

automatically updating the portion of the system registry by referring to the corresponding self-registration data built into the resource fork of the application program module.

2. The method of claim 1, wherein the step of determining that the predefined event that affects the proper functioning of the application program module comprises one of the steps of:

determining that a condition of at least one of an application program module folder, and a file, and a directory has changed;

determining that a storage path for at least one of the application program module folder, and the file, and the directory has changed;

determining that at least one of the application program module folder, and the file, and the directory has been modified;

determining that at least one of the application program module folder, and the file, and the directory has been renamed;

determining that a hard drive of the computing device has been renamed;

determining that a new operating system has been installed;

determining that an operating system has been reinstalled;

determining that the application program module has been executed;

determining that an installer application program module has been moved to a different hard drive on the computing device;

determining that a system administrator has pushed the application program module to a user;

determining that a modification date of at least one of the application program module folder, and the file, and the directory has been changed;

determining that a variable specified by a developer of the application program module has changed; and

determining that a different application has been loaded on the computing device.

3. The method of claim 1, wherein the registration cache IS specific to the application program module.

4. The method of claim 1, wherein the step of determining whether the portion of the system registry of the computing device needs to be updated comprises the step of examining the information in the registration cache that has changed, to determine if the change should be reflected in the system registry.

5. The method of claim 1, wherein the step of determining whether the portion of the system registry of the computing device needs to be updated comprises the step of accessing the portion of the system registry in order to change that portion to include the change in the information stored in the registration cache.

6. The method of claim 1, wherein the step of updating comprises the step of updating the portion of the system registry such that it substantially matches the information of said registration cache that has changed.

7. The method of claim 1, wherein the step of updating comprises the steps of:

searching through a predetermined folder for one of an application file and a dynamic link library file;

upon detecting one of the application file and the dynamic link library file, opening a resource fork in association with the application file;

determining whether there is a self-registration resource in the resource fork; and

if there is a self-registration resource in the resource fork, then automatically registering the self-registration resource in the system registry.

8. The method of claim 7, wherein the step of registering the self-registration resource comprises the step of initiating a dynamic link library routine.

9. The method of claim 8, wherein the dynamic link library routine is selfreg.dll.

10. The method of claim 7, further comprising the steps of:

determining whether there is an Object Linking and Embedding (OLE) Type Library (OTLB) resource in the resource fork; and

if there is an OTLB resource III the resource fork, then automatically registering the OTLB resource in the system registry.

11. The method of claim 10, wherein the step of automatically registering the OTLB resource comprises the step of initiating an OLE call.

12. The method of claim 10, wherein the OLE call is RegisterTypeLib.

13. A memory medium having machine executable instructions for carrying out the steps of claim 1.

14. A system for automatically updating a portion of a system registry based of the system upon an occurrence of a predefined event that affects the proper functioning of an application program module in the system, comprising:

a memory that stores;

a system registry;

a registration cache; and

the application program module; and

a processor coupled to the memory, wherein the memory stores machine instructions causing the processor to;

build a portion of self-registration data into a resource fork of the application program module, the self-registration data being automatically updatable to be in sync with one or more corresponding linking files of the application program, the self-registration data being part of the resource fork of the application program module such that explicit calls to separate self-registration files are avoided;

determine that the predefined event that affects the proper functioning of the application program module in the system has occurred; and

if so,

determine whether the portion of the system registry of the system needs to be updated because at least one of the following conditions exists;

any information in a registration cache has changed; and

a registration cache does not exist; and

if so,

automatically update the portion of the system registry by referring to the corresponding self-registration data built into the resource fork of the application program module.

15. A computer program product for implementing a method for automatically updating a portion of a system registry of a computing device based upon the activation of a user-defined trigger, the computer program product comprising one or more computer-readable media having thereon computer-executable instructions that, when executed by one or more processors of the computing system, cause the computing system to perform the method, the method comprising:

building a portion of self-registration data into a resource fork of the application program module, the self-registration data being automatically updatable to be in sync with one or more corresponding linking files of the application program, the self-registration data being part of the resource fork of the application program module such that explicit calls to separate self-registration files are avoided;
