Fig. 1 shows described according to an embodiment of the invention browser control part restoration methods process flow diagram, and as shown in Figure 1, described method comprises step:
S100: intercept and capture the process of the page process creation moving object of browser, create agent object and replace the actual moving object that will create, described agent object moves in page process.
Wherein, described moving object is exactly real browser control part, for example real ActiveX object, i.e. ActiveX control; Described agent object can be the browser control part of simulation, the ActiveX control of for example simulating, and described agent object moves in page process.
The present invention is as follows in the concrete example explanation:
In webpage, have in the situation of ActiveX control, when browser creates ActiveX control, can be according to control CLSID or ProgID inquiry registration table, wherein can obtain CLSID by CLSIDFromProgID, whether the system of checking has thus installed corresponding control, then can continue constructive process if install.Browser obtains the IUnknown pointer of corresponding control by calling CoGetClassObject, then carry out mutual operation by standard interface.The CoGetClassObject implementation is, go to registry query ActiveX path by CLSID, after obtaining the ActiveX path, call LoadLibrary and load ActiveX control, call its derivative function DllGetClassObject and obtain class factory's pointer (IClassFactory), the CreateInstance method of then calling IClassFactory obtains IUnknown pointer corresponding to ActiveX control.
When loading ActiveX control, interception CoGetClassObject creates an ActiveX control agent object, and this ActiveX control agent object comprises a series of interfaces, IUnknown pointer a lot of standard interfaces that will call for example, such as IOleObject, IViewObject etc.Then when calling the CreateInstance of IClassFactory, the ActiveX control agent object that creates is returned to the IUnknown pointer of ActiveX control.
S200: in the detached process that is independent of the browser page process, create the described actual moving object that will create, described moving object is moved in detached process.
Still concrete example explanation the present invention is as follows: when the page activates described ActiveX control, extract the relevant informations such as attribute, URL, size of this control, then create a detached process.Specifically, create a file (document), insert therein an object, this detached process is called CoGetClassObject, tackle this CoGetClassObject, create another ActiveX control moving object again, this ActiveX control moving object comprises a series of interfaces, IUnknown pointer a lot of standard interfaces that will call for example, such as IOleObject, IViewObject etc.Then when calling the CreateInstance of IClassFactory, this another ActiveX control moving object that creates is returned to the IUnknown pointer of the ActiveX control of detached process.
S300: agent object judges by communicating by letter with detached process and/or its moving object whether moving object interrupts, and if so, agent object sends active information to detached process, activity of constructing object again in detached process, process ends; Otherwise, direct process ends.
Concrete example explanation the present invention is as follows: create respectively a window related with this control object and communicate being used in two ActiveX control objects that create.Specifically two control object can be for size, focus, refresh, script and other information carries out alternately.The method according to this invention can be tackled all requests in above two processes, realizes information interaction between these two processes by two ActiveX control objects that are pre-created.The concrete computation process of ActiveX control is carried out in detached process thus, thereby can not affect the process of former webpage.
Described step S300 further comprises:
S310: agent object judge by communicating by letter with detached process and/or its moving object moving object whether stuck and/or detached process whether collapse.Particularly, agent object is regularly inquired the running state information of detached process and/or its moving object, and according to described running state information judge moving object whether stuck and/or detached process whether collapse.If find following at least one according to described running state information: the message circulation inertia of moving object place thread, the window of moving object is hung up, and always hurrying of moving object thread judges that then moving object is stuck; If find following at least one according to described running state information: the main window in the detached process does not exist, and the window in the moving object does not exist, then judge the detached process collapse.
Agent object is regularly inquired the running state information of detached process and/or its moving object, can realize this supervisory control action with a lot of modes specifically, for instance, can be message window of each moving object binding in the detached process of opening; Make the agent object of page process inquire about termly this message window, to monitor the whether normally operation of this moving object.
S320: if moving object is stuck, then agent object stops and the communicating by letter and send described moving object from active information to detached process, activity of constructing object again in detached process.
S330: if detached process collapse then creates new detached process, agent object sends active information to detached process, activity of constructing object again in detached process.
By the execution of said method step, the in time interruption of identification activity object, and in moving object, have no progeny it is in time reactivated, shorten the response time.
In addition, can also comprise step after the described step S200:
P1: agent object is regularly inquired the operation information of moving object, and preserves described operation information.
Correspondingly, among the described step S300, described agent object sends active information to detached process, and activity of constructing object again in detached process further is:
Agent object sends described active information and described operation information to detached process;
According to described active information, activity of constructing object again in detached process;
According to described operation information, obtain the interruption position of former moving object, the new moving object that creates of order continues operation at described interruption position place.
Wherein, described active information mainly is: the information such as the attribute of moving object, URL, position, size; Described operation information is the operation progress msg of moving object.By adopting described step P1, and described step S300 is changed accordingly, can guarantee that moving object can begin to rerun at the interruption position place, restart completely in compared to existing technology, obviously further improved response efficiency.
Can also whether reactivate the moving object of having interrupted to improve the interactive performance with the user by user selection among the described step S300, particularly, it may further include:
Described agent object judges by communicating by letter with detached process whether moving object interrupts, and if so, the prompting user moving object is interrupted;
Receive user's reactivation instruction;
Agent object sends active information to detached process, activity of constructing object again in detached process.
Can also comprise step after the described step S300:
