RE: Special charaters are displayed in inverted order by CTreeCtrl

I build a file browser like tree with CTreeCtrl. Now, if the control has to
display a drive like "C:", it instead displays ":C". The same happens with
"Program Files (x86)" which is displayed as ")Program Files (x86". So, it
seems that if the the last character is a special character, it becomes the
first character in display name.
Is this a unicode problem? Anyway, very strange.

Here is my coding:

CFileSystem fs;
    wchar_t d[3];
    LPTVINSERTSTRUCTW itemstruc = NULL;
    CString text;

    //Load static images
    m_FileViewImages.Create(IDB_FILE_VIEW, 16, 0, RGB(0,0,0));
    //Set image list
    this->SetImageList(&m_FileViewImages, TVSIL_NORMAL);
    //Set 24 bit bitmaps for static images
    this->ChangeVisualStyle( );

    int num = fs.GetNumberDrives( );
    for(int j = 1; j<num+1; j++){
      //Get drive name
      fs.GetDriveByNumber(j,d);
      text = CString(d);
      if(fs.IsDriveActive(d)==TRUE){
        itemstruc = new TVINSERTSTRUCTW;
        itemstruc->hParent = NULL;
        //Set item mask
        itemstruc->item.mask = TVIF_CHILDREN|TVIF_HANDLE|TVIF_IMAGE|
                               TVIF_STATE|TVIF_TEXT|TVIF_SELECTEDIMAGE;
        //Set state mask
        itemstruc->item.stateMask = TVIS_BOLD|TVIS_OVERLAYMASK|TVIS_SELECTED;
        itemstruc->item.cChildren = 1;
        itemstruc->item.pszText = (WCHAR*)text.GetBuffer( );
        itemstruc->item.cchTextMax = 3;
        itemstruc->item.iImage = 3;
        itemstruc->item.iSelectedImage = 3;
        HTREEITEM item = InsertItem(itemstruc);
        SetItemState(item,TVIS_BOLD,TVIS_BOLD);
        //SetItemState(item,TVIS_SELECTED,TVIS_SELECTED);
        delete itemstruc;
      }
    }

Any ideas are really appreciated.
