我們在編寫ActiveX控件時，如果用在瀏覽器中，經常都會彈出現在運行的腳本不安全的提示， 如果給客戶使用，將會帶來極大不便。按照MSDN的介紹通常有兩種一種是實現IObjectSafe接口，一種是通過修改注冊表的方法。一般如果用ATL開發ActiveX控件，就用實現ObjectSafe接口的方法。如果用MFC開發，我覺得還是用修改注冊表的方法比較方便。下面我們將第二種方法：
要包括兩個文件
1.#include "comcat.h"
2.#include "Objsafe.h"
// 本控件的CLSID,注冊表用
1.const GUID CDECL CLSID_SafeItem =
2.{ 0x7AE7497B, 0xCAD8, 0x4E66, { 0xA5,0x8B,0xDD,0xE9,0xBC,0xAF,0x6B,0x61 } };
// 創建組件種類
01.HRESULT CreateComponentCategory(CATID catid, WCHAR* catDescription)
02.{
03.ICatRegister* pcr = NULL ;
04.HRESULT hr = S_OK ;
05.
06.hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,
07.NULL, CLSCTX_INPROC_SERVER, IID_ICatRegister, (void**)&pcr);
08.if (FAILED(hr))
09.return hr;
10.
11.// Make sure the HKCR\Component Categories\{..catid...}
12.// key is registered.
13.CATEGORYINFO catinfo;
14.catinfo.catid = catid;
15.catinfo.lcid = 0x0409 ; // english
16.
17.// Make sure the provided description is not too long.
18.// Only copy the first 127 characters if it is.
19.int len = wcslen(catDescription);
20.if (len>127)
21.len = 127;
22.wcsncpy(catinfo.szDescription, catDescription, len);
23.// Make sure the description is null terminated.
24.catinfo.szDescription[len] = ''\0'';
25.
26.hr = pcr->RegisterCategories(1, &catinfo);
27.pcr->Release();
28.
29.return hr;
30.}
// 注冊組件種類
01.HRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid)
02.{
03.// Register your component categories information.
04.ICatRegister* pcr = NULL ;
05.HRESULT hr = S_OK ;
06.hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,

08.if (SUCCEEDED(hr))
09.{
