这是一个要列出本机上所有控件的vc程序,与com有关,我不太懂,请高手指点一下,我想把它转成c#,要怎样对应起来啊,请大家不吝赐教,谢谢//Initialise COM libraries
CoInitialize (NULL);//The Component Category Manager implemented by System implements
//this interface
ICatInformation *pCatInfo=NULL;//Create an instance of standard Component Category Manager
HRESULT hr=CoCreateInstance (CLSID_StdComponentCategoriesMgr ,
NULL,
CLSCTX_INPROC_SERVER,
IID_ICatInformation ,
(void **)&pCatInfo);//Increase ref count on interface
pCatInfo->AddRef ();//IEnumGUID interface provides enumerator for enumerating through
//the collection of COM objects
IEnumGUID *pEnumGUID=NULL;//We are intersted in finding out only controls so put CATID_Control
//in the array
CATID pcatidImpl[1];
CATID pcatidReqd[1];
pcatidImpl[0]=CATID_Control;//Now enumerate the classes i.e. COM objects of this type.
pCatInfo->EnumClassesOfCategories (1,
pcatidImpl,
0,
pcatidReqd ,
&pEnumGUID);//Enumerate as long as you get S_OK
CLSID clsid;while( (hr= pEnumGUID->Next( 1, &clsid, NULL ))==S_OK )

USERCLASSTYPE_FULL The full type name of the class.
USERCLASSTYPE_SHORT A short name (maximum of 15 characters) that
is used for popup menus and the Links dialog
box.
USERCLASSTYPE_APPNAME The name of the application servicing the class
and is used in the Result text in dialog boxes.

OleRegGetUserType (clsid,USERCLASSTYPE_FULL,&bstrClassName);
CString strControlName(bstrClassName);
//Add string in our listbox
m_list1.AddString (strControlName);
}//we are done so now release the interface ptr
pCatInfo->Release ();CoUninitialize ();另外它引用了"comcat.h",这个文件是做什么用的啊

那个代码怎么看不懂亚/
另外,引用计数不正确,“pCatInfo->AddRef();”语句不需要。
