Abstract

The invention discloses a method and client for using an embedded ActiveX plug-in in a browser. The method comprises: detecting that the browser is to load an ActiveX plug-in; judging whether the ActiveX plug-in has already been installed in a computer system where the browser is currently located; if it is determined that the ActiveX plug-in has already been installed in the computer system, intercepting the loading information about the ActiveX plug-in and loading the ActiveX plug-in embedded in the browser; and if it is determined that the ActiveX plug-in has not been installed in the computer system, generating a specific registry key value related to the embedded ActiveX plug-in, and loading the ActiveX plug-in embedded in the browser according to the specific registry key value.

First claim

The invention claimed is:

1. A method for using an embedded ActiveX plug-in in a browser, comprising:
detecting, by at least one processor, that the browser is to load an ActiveX plug-in;
determining, by the at least one processor, whether the ActiveX plug-in has already been installed in a computer system where the browser is currently located;
if it is determined that the ActiveX plug-in has already been installed in the computer system, intercepting, by the at least one processor, loading information about the ActiveX plug-in and loading the ActiveX plug-in embedded in the browser; and
if it is determined that the ActiveX plug-in has not been installed in the computer system, generating, by the at least one processor, a specific registry key value related to the embedded ActiveX plug-in by placing a storage path of the ActiveX plug-in embedded in the browser under the specific registry key value, and loading the ActiveX plug-in embedded in the browser according to the specific registry key value and based on the storage path of the ActiveX plug-in embedded in the browser, a browser object label obtaining an installation position of the ActiveX plug-in via the specific registry key value by hooking a registry reading function, and accessing the specific registry key value to redirect from the installation position of the Active X plug-in to the storage path of the ActiveX plug-in embedded in the browser, thereby loading the ActiveX plug-in embedded in the browser.

2. The method according to claim 1 , further comprising determining whether the ActiveX plug-in has already been installed in the computer system based on a class identifier of the ActiveX plug-in.

3. The method according to claim 2 , wherein the class identifier is obtained based on a program identifier in a class identifier obtaining function.

4. The method according to claim 1 , wherein the intercepting the loading information about the ActiveX plug-in and loading the ActiveX plug-in embedded in the browser comprises:
obtaining the storage path of the ActiveX plug-in embedded in the browser by hooking a storage path query function of the ActiveX plug-in and according to a class identifier of the ActiveX plug-in; and
loading the ActiveX plug-in embedded in the browser based on the storage path.

5. The method according to claim 4 , further comprising:
invoking a dynamic link library loading function to load the dynamic link library of the embedded ActiveX plug-in;
obtaining a class factory pointer by invoking an export function; and
creating and loading the ActiveX plug-in embedded in the browser based on the class factory pointer.

6. The method according to claim 1 , further comprising: by hooking the registry reading function, accessing the specific registry key value of a program identifier to redirect to the storage path of the ActiveX plug-in embedded in the browser.

7. A client having an embedded ActiveX plug-in, comprising:
a memory having instructions stored thereon; and
at least one processor to execute the instructions to perform operations comprising:
detecting that a browser is to load an ActiveX plug-in;
determining whether the ActiveX plug-in has already been installed in a computer system where the client is currently located;
if it is determined that the ActiveX plug-in has already been installed in the computer system, intercepting loading information about the ActiveX plug-in and loading the ActiveX plug-in embedded in the browser; and
if it is determined that the ActiveX plug-in has not been installed in the computer system, generating a specific registry key value related to the embedded ActiveX plug-in by placing a storage path of the ActiveX plug-in embedded in the browser under the specific registry key value, and loading the ActiveX plug-in embedded in the browser according to the specific registry key value and based on the storage path of the ActiveX plug-in embedded in the browser, a browser object label obtaining an installation position of the ActiveX plug-in via the specific registry key value by hooking a registry reading function, and accessing the specific registry key value to redirect from the installation position of the Active X plug-in to the storage path of the ActiveX plug-in embedded in the browser, thereby loading the ActiveX plug-in embedded in the browser.

8. The client according to claim 7 , the operations further comprising determining whether the ActiveX plug-in has already been installed in the computer system based on a class identifier of the ActiveX plug-in.

9. The client according to claim 8 , wherein the class identifier is obtained based on a program identifier in a class identifier obtaining function.

10. The client according to claim 7 , wherein the intercepting the loading information about the ActiveX plug-in and loading the ActiveX plug-in embedded in the browser comprises:
obtaining the storage path of the ActiveX plug-in embedded in the browser by hooking a storage path query function of the ActiveX plug-in and according to a class identifier of the ActiveX plug-in; and
loading the ActiveX plug-in embedded in the browser based on the storage path.

11. The client according to claim 10 , the operations further comprising:
invoking a dynamic link library loading function to load the dynamic link library of the embedded ActiveX plug-in;
obtaining a class factory pointer by invoking an export function; and
creating and loading the ActiveX plug-in embedded in the browser based on the class factory pointer.

12. A non-transitory computer readable medium having instructions stored thereon that, when executed by at least one processor, cause the at least one processor to perform operations for using an embedded ActiveX plug-in in a browser, the operations comprising:
detecting that the browser is to load an ActiveX plug-in;
determining whether the ActiveX plug-in has already been installed in a computer system where the browser is currently located;
if it is determined that the ActiveX plug-in has already been installed in the computer system, intercepting loading information about the ActiveX plug-in and loading the ActiveX plug-in embedded in the browser; and
if it is determined that the ActiveX plug-in has not been installed in the computer system, generating a specific registry key value related to the embedded ActiveX plug-in by placing a storage path of the ActiveX plug-in embedded in the browser under the specific registry key value, and loading the ActiveX plug-in embedded in the browser according to the specific registry key value and based on the storage path of the ActiveX plug-in embedded in the browser, a browser object label obtaining an installation position of the ActiveX plug-in via the specific registry key value by hooking a registry reading function, and accessing the specific registry key value to redirect from the installation position of the Active X plug-in to the storage path of the ActiveX plug-in embedded in the browser, thereby loading the ActiveX plug-in embedded in the browser.
