CItemIDList class helps manage ITEMIDLIST more easily

Introduction

This is a class helps you manage ITEMIDLIST easier. The CItemIDList class holds a pointer to a ITEMIDLIST structure (the pointer is in CItemIDList::m_pidl). It also has public static member functions which you can use as global functions.(Version 2.0)

Constructors

CItemIDList(LPCTSTR pcszPath);   

Construct with a path string.

CItemIDList(LPITEMIDLIST pidl);   

Construct with LPITEMIDLIST.(Copy it,and free on destruct)

CItemIDList(CItemIDList& iidl);   

Construct with another class object.

CItemIDList(void);   

Construct class instance with m_pidl empty.

Member functions

int GetIconIndex(void) const;

Get folder item's icon index in system image list.

BOOL GetDisplayName(LPTSTR pszBuf,DWORD dwFlags=SHGDN_NORMAL) const;   

Retrieve pidl's dislpay name.

CItemIDList Duplicate(UINT nCount=-1) const;   

Copy a pidl due to the count number.

inline BOOL IsEmpty(void) const;   

Whether m_pidl is NULL.

CItemIDList GetAt(UINT nIndex) const;   

Return a relative pidl at specified index.

BOOL Create(LPITEMIDLIST pidlf);   

Create from a LPITEMIDLIST.

inline UINT GetCount(void) const;   

Get pidl count.

inline UINT GetSize(void) const;   

Get pidl's size,in byte.

inline void Empty(void);   

Free m_pidl and set to NULL.

void GetPath(LPTSTR pszPath) const;   

Retrieve full path.(only available for full-quality pidl)

inline HRESULT GetUIObjectOf(REFIID riid,LPVOID* ppOut,HWND hWnd=NULL);   

Retrieve other shell interface.Same as IShellFolder::GetUIObjectOf.

inline void Split(LPSHELLFOLDER& lpsf,CItemIDList& ciid) const;   

Get IShellFolder interface and the tail pidl cell from a full-quality pidl.

CItemIDList GetLastPidl(void) const;  

Retrieve the tail pidl cell.

void GetToolTipInfo(LPTSTR pszToolTip,UINT cbSize) const;  

Retrieve the tooltip info of the m_pidl.

void Attach(LPITEMIDLIST pidl);  

Attach a pidl.

LPITEMIDLIST Detach(void); 

Detach a pidl.

Operators

CItemIDList operator+(CItemIDList& piidl);   

Concat two pidls.

operator LPITEMIDLIST(void) const;   

Get m_pidl.

operator LPCITEMIDLIST(void) const;   

Get m_pidl convert to LPCITEMIDLIST.

const CItemIDList& operator=(CItemIDList& ciidl1);   

Copy from another class instance.

const CItemIDList& operator=(LPITEMIDLIST pidl);   

Copy from a LPITEMIDLIST.

operator+=(CItemIDList& ciidl);   

Add a new pidl to m_pidl's tail.

BOOL operator==(CItemIDList& ciidl);   

Query whether two pidl's name is same.

CItemIDList operator[](UINT nIndex);   

Return a relative pidl at specified index.(Same as CItemIDList::GetAt(UINT nIndex))

Example

#include "ItemIDList.h"
#include <windows.h>
#include <iostream.h>

//Some test code...
void main()
{
	char szFile[MAX_PATH];
	ZeroMemory(szFile,MAX_PATH);

	OPENFILENAME info;
	ZeroMemory(&info,sizeof(info));

	info.lStructSize=sizeof(info);
	info.lpstrFile=szFile;
	info.hwndOwner=NULL;
	info.nMaxFile=MAX_PATH;

	if(GetOpenFileName(&info))
	{
		CItemIDList item(szFile),item2;
		char szName[MAX_PATH];
		item.GetDisplayName(szName);
		cout<<szName<<endl;

		item.GetToolTipInfo(szName,MAX_PATH);
		cout<<szName<<endl;

		item2=item;
		item2.GetPath(szName);
		cout<<szName<<endl;

		item2=item[item.GetCount()-1];
		item2.GetDisplayName(szName);
		cout<<szName<<endl;

		item2=item.GetAt(0);
		item2.GetDisplayName(szName);
		cout<<szName<<endl;

		CItemIDList item3;
		item3=item.Duplicate(item.GetCount()-1);
		item3.GetPath(szName);
		cout<<szName<<endl;

		item3=item.Duplicate(item.GetCount()-1)+item2;
		item3.GetPath(szName);
		cout<<szName<<endl;
	}
}
