Introduction

The following classes deal mainly with the areas of the shell namespace, links, app and task bars etc.

Links

COXHyperLinkAction class is to some extent a wrapper around the ShellExecute function.

See the Static Hyperlink article for more on this class and its usage.

Application Bar

The COXAppBar class provides the functionality of a Windows shell application bar.

Typically you will derive a class from an instance of the template class after designing the dialog that will be used in the application bar:

class CMyApplicationBarDlg : public COXAppBar<CDialog> {...}

Then in your constructors initialization list you will initialize the base class with the dialog ID and parent window:

CMyApplicationBarDlg::CMyApplicationBarDlg(CWnd* pParent /*=NULL*/)
: COXAppBar<CDialog>(CMyApplicationBarDlg::IDD, pParent)
{

}

To start using your class just call Register(TRUE), which registers/unregisters the app bar with the windows shell.

Shell Namespace

COXShellFolderTree, COXShellNamespaceNavigator, and COXShellObjectList allow for iterating and viewing the namespace aspects of the Windows shell.

In this sample, the CFolderTree class is declared as a COXTreeComboDropdown using COXShellFolderTree:

class CFolderTree : public COXTreeComboDropDown<COXShellFolderTree>  
{
public:
     CFolderTree();
     virtual BOOL CanSelectItem(HTREEITEM hItem);
     virtual ~CFolderTree();
     virtual CString GetSelectedItemText();
};

This class is then declared as a member and created directly - it is then paired with the CComboBox extension class COXComboPickerCtrl to act as the dropdown portion of the control:

// Implementation
protected:
    COXComboPickerCtrl m_pckShell;
    CFolderTree m_cmbShell;

    //initializing shell tree
    VERIFY(m_pckShell.Create(WS_CHILD | WS_VISIBLE | CBS_OWNERDRAWFIXED | 
        CBS_DROPDOWNLIST, 
        CRect(20,30,160,40),this,IDC_PICKER));
    VERIFY(m_cmbShell.Create(WS_CHILD | TVS_HASBUTTONS | TVS_TRACKSELECT | 
        TVS_LINESATROOT | TVS_HASLINES,
        CRect(0,0,0,0),this,IDC_COMBO));

    m_cmbShell.SetOwnerCombo(&m_pckShell);
    m_pckShell.AttachDropDown(&m_cmbShell);
    m_pckShell.SetMaxDropdownHeight(200);
    m_cmbShell.InitializeTree();        // this will initialize the namespace 
                                        // tree beginning with the desktop 
                                        // folder (default)
    ...

Shortcut

COXShortcut provides a wrapper for the IShellLink and IPersistFile interfaces.

The demo simply exercises the COX Shortcut m_scDemo object once opened, calling the specified interfaces:

...
CASE(FN_GETARGUMENTS)
    if (bSuccess == m_scDemo.GetArguments(sBuffer))
        m_sOutput.Format(fmtS, sBuffer);

CASE(FN_GETCURFILE)
    sBuffer = m_scDemo.GetCurFile();
    m_sOutput.Format(fmtS, sBuffer);

CASE(FN_GETDESCRIPTION)
    if (bSuccess == m_scDemo.GetDescription(sBuffer))
        m_sOutput.Format(fmtS, sBuffer);
...

Taskbar

The COXTaskbarIcon class encapsulates Win32 API's Shell_NotifyIcon() function to let you easily show, hide, or change icons in Window 95's or Windows NT's taskbar notification area.

See the Taskbar Icon article for more on this class and its usage.
