How do you know SMS belong to which folder in MAPI?

Well,somethimes you might want to know that this SMS is in which folder,for example in Drafts folder,in Inbox folder or...?
A quick not is that never rely on results from PR_DISPLAY_NAME because names like "Inbox","Drafts Folder" can be localized.
Here is the code snippet i use.
You have to use it like this.

if (isFolderTypeSame(pSession,pFolder,PR_CE_IPM_INBOX_ENTRYID))

You can use these values for third parameter.
PR_CE_IPM_DRAFTS_ENTRYID
CE_IPM_INBOX_ENTRYID
PR_IPM_OUTBOX_ENTRYID
PR_IPM_WASTEBASKET_ENTRYID
PR_IPM_SENTMAIL_ENTRYID

bool isFolderTypeSame(IMAPISession *m_pSession,LPMAPIFOLDER pFolder,ULONG _PR_FOLDERTYPE)
{
    HRESULT hr = E_FAIL;
    CComPtr<IMsgStore> pms ;
    ULONG cItems;
 SizedSPropTagArray(2, rgtagsFldr) = {2 , PR_OWN_STORE_ENTRYID,PR_ENTRYID};
 ULONG entryid[] = { 1, _PR_FOLDERTYPE };
    LPSPropValue fldrprops=NULL,msgstoreprops = NULL;
 ULONG result=0;

    // This method assumes that the CALLER already logged on to a MAPISession
    if (!m_pSession)
        CHR(E_FAIL);  

    // Now request the PR_OWN_STORE_ENTRYID on the folder.  This is the
    // ENTRYID of the message store that owns the folder object.
    hr = pFolder->GetProps((SPropTagArray *) &rgtagsFldr, MAPI_UNICODE, &cItems, &fldrprops);
    CHR(hr);


    // Now open the message store object.
    hr = m_pSession->OpenEntry(fldrprops[0].Value.bin.cb,(LPENTRYID)fldrprops[0].Value.bin.lpb,NULL, 
  0, NULL, (LPUNKNOWN*)&pms);
    CHR(hr);


    // Get the ENTRYID of the wastebasket for the message store
    hr = pms->GetProps((LPSPropTagArray)entryid, MAPI_UNICODE, &cItems, &msgstoreprops);
    CHR(hr);


 m_pSession->CompareEntryIDs(fldrprops[1].Value.bin.cb,(LPENTRYID)fldrprops[1].Value.bin.lpb,msgstoreprops[0].Value.bin.cb,(LPENTRYID)msgstoreprops[0].Value.bin.lpb,0,&result);

Error:
    MAPIFreeBuffer(msgstoreprops);
    MAPIFreeBuffer(fldrprops);
 return result;
}
