When compiling IE ActiveX, you always want to get the script object in IE to facilitate Script Processing in ActiveX.
1. A widely spread method on the Internet is to obtain the script (JavaScript) object through the top-level method, which is very good at obtaining the top-level script, however, in the IFRAME framework, Javascript in IFRAME cannot be accurately obtained. The following is an example Code : 1 Iserviceprovider * ISP, * Isp2 = NULL;
2
3 Do {
4 Hresult HR = S_ OK;
5
6 M_pclientsite -> Addref ();
7 HR = M_pclientsite -> QueryInterface (iid_iserviceprovider, reinterpret_cast < Void **> ( & ISP ));
8 M_pclientsite -> Release ();
9
10 If (Failed (HR ))
11 {
12 Break ;
13 }
14
15 ISP -> Addref ();
16 HR = ISP -> Queryservice (sid_stoplevelbrowser, iid_iserviceprovider, reinterpret_cast < Void **> ( & Isp2 ));
17 ISP -> Release ();
18
19 If (Failed (HR ))
20 {
21 Break ;
22 }
23
24 Isp2 -> Addref ();
25 HR = Isp2 -> Queryservice (sid_swebbrowserapp, iid_iwebbrowser2, reinterpret_cast < Void **> ( & Pwebbrowser ));
26 Isp2 -> Release ();
27
28 ISP -> Release ();
29
30 If (Failed (HR ))
31 {
32 Break ;
33 }
34
35
36 Pwebbrowser -> Addref ();
37 HR = Pwebbrowser -> Get_document (idispatch ** ) & Phtmldocument );
38 Pwebbrowser -> Release ();
39
40 Isp2 -> Release ();
41
42 If (Failed (HR ))
43 {
44 Break ;
45 }
46
47 Phtmldocument -> Addref ();
48 HR = Phtmldocument -> Get_script ( & Pscript );
49 Phtmldocument -> Release ();
50
51 Pwebbrowser -> Release ();
52
53
54 If (Failed (HR ))
55 {
56 Break ;
57 }
58
59 } While (False ); First query the service interface, and then query the service provider of the top-level browser through the service interface. Then, the server provider queries the browser, obtains the document object from the browser, and then obtains the JavaScript Object. The method is cumbersome, but the overall meaning is clear. 2. If you want to obtain JavaScript objects in the IFRAME framework, you need to use another method. The code is very simple. The key is to be familiar with IE's COM interface. 1 Ccomptr < Iolecontainer > Spcontainer;
2 Hresult HR = M_pclientsite -> Getcontainer ( & Spcontainer );
3 If (HR = S_ OK)
4 {
5 Ccomqiptr < Ihtmldocument2 > Spdoc = Spcontainer;
6 Spdoc -> Get_script ( & Pscript );
7 Theapp. pscript = Pscript;
8 } It is easy to understand. first obtain the container object, that is, the so-called ihtmldocument2 object, and then obtain the script object from the object. Note: Is there any other way to obtain the IE Script object?
