怎么列举计算机安装了那些ACTIVEX组件？(100)

怎么列举计算机安装了那些ACTIVEX组件？ 类似于DELPHI编译器自带的安装ACTIVEX组件界面的效果，类似于菜单Component->Import ActiveX 那个界面的效果。

我看了一下MSDN的OLEView源代码，居然用注册表搞的。我试过WIN 7下的TComAdminCatalog组件，不过不行。不过效果还一般。不知道有没有代码给我参考一下。我贴出代码，大家看看。 HKEY hkCLSID ; if (RegOpenKey( HKEY_CLASSES_ROOT, _T("CLSID"), &hkCLSID) == ERROR_SUCCESS) { CObjectData* lpOD ; LONG cb ; TCHAR szBuf[_MAX_PATH + 1] ; TCHAR szName[64] ; TCHAR szCLSID[64] ; DWORD dwIndex ; for ( dwIndex = 0 ; RegEnumKey( hkCLSID, dwIndex, szCLSID, sizeof(szCLSID)) == ERROR_SUCCESS ; ++dwIndex ) { lpOD = NULL ; cb = sizeof(szName); if (RegQueryValue( hkCLSID, (LPTSTR)szCLSID, szName, &cb) == ERROR_SUCCESS) { lpOD = new CObjectData ; lpOD->m_nType = CObjectData::typeObject ; ASSERT(lpOD) ; ::CLSIDFromString( CT2OLE(szCLSID), &lpOD->m_clsid); lpOD->m_szProgID[0] = '/0' ; // Assume it's an object lpOD->m_uiBitmap = BMINDEX(IDB_OBJECT) ; // Now find out more about it. // // #1 Look in CLSID/{clsid} for the /Control key // #2 Assume it is an 'non-embeddable' OLE 2.0 object // #3 If /<progid>/NotInsertable exists we'redo

void CObjTreeView::ExpandClassification( NM_TREEVIEW* pnmtv )。不过效果和DELPHI自带的，Visual Studio 2008自带的有差距，还有一大片空的呢。有没有简单一点的？给位仁兄。
