LPITEMIDLIST pidl;
LPITEMIDLIST pidlRoot;
LPMALLOC lpMalloc; TCHAR pszPath[MAX_PATH];
_tcscpy(pszPath, ""); BROWSEINFO bi = { m_hWnd, NULL, (char *)(LPCTSTR)pszPath, "请选择存放的路径：", BIF_BROWSEFORCOMPUTER  | BIF_RETURNONLYFSDIRS, NULL, 0L, 0};

if (0 != SHGetSpecialFolderLocation(HWND_DESKTOP, CSIDL_DRIVES, &pidlRoot)) 
{
return;
} if (NULL == pidlRoot) 
{
return;  
} bi.pidlRoot = pidlRoot;  pidl = SHBrowseForFolder(&bi); 

if (NULL != pidl)
{
SHGetPathFromIDList(pidl, pszPath);  m_strFilePath = pszPath;
}
else
{
return;
}

// Get the shell's allocator to free PIDLs 
if (!SHGetMalloc(&lpMalloc) && (NULL != lpMalloc)) 
{ 
if (NULL != pidlRoot)
{ 
lpMalloc->Free(pidlRoot); 
}  

if (NULL != pidl) 
{ 
lpMalloc->Free(pidl); 
}

lpMalloc->Release(); 
}

void CSelFileDlg::OnAdddir() 
{
// TODO: Add your control notification handler code here
LPMALLOC pMalloc;
BROWSEINFO bi;
LPITEMIDLIST pidl; 
         TCHAR m_directory[MAX_PATH];

::ZeroMemory(&bi, sizeof(bi));

// Gets the Shell's default allocator
if (::SHGetMalloc(&pMalloc) == NOERROR)
{
// Get help on BROWSEINFO struct - it's got all the bit settings.

bi.hwndOwner=NULL;
        bi.pidlRoot=NULL;//为NULL,则已桌面为根,
bi.lpszTitle=_T("请选择文件夹");//
bi.ulFlags=BIF_RETURNONLYFSDIRS;
bi.lpfn=NULL;
bi.lParam=NULL;
bi.pszDisplayName = m_directory; 
// This next call issues the dialog box.
if ((pidl = ::SHBrowseForFolder(&bi)) != NULL)
{
if (!::SHGetPathFromIDList(pidl, m_directory)) 
pMalloc->Free(pidl); 
//m_directory 就保存了你选择的文件夹
}  
pMalloc->Release();
} // 
    m_bdirectory = true;
}

Answer 4

CString sFolder;  //存放选定一个文件夹
    LPMALLOC pMalloc;    // Gets the Shell's default allocator
    if (::SHGetMalloc(&pMalloc) == NOERROR)
    {
        BROWSEINFO bi;
        char pszBuffer[MAX_PATH];
        LPITEMIDLIST pidl;        bi.hwndOwner = GetSafeHwnd();
        bi.pidlRoot = NULL;
        bi.pszDisplayName = pszBuffer;
        bi.lpszTitle = _T("Select a directory...");
        bi.ulFlags = BIF_RETURNFSANCESTORS | BIF_RETURNONLYFSDIRS;
        bi.lpfn = NULL;
        bi.lParam = 0;        // This next call issues the dialog box.
        if ((pidl = ::SHBrowseForFolder(&bi)) != NULL)
        {
            if (::SHGetPathFromIDList(pidl, pszBuffer))
            { 
            // At this point pszBuffer contains the selected path
sFolder = pszBuffer;
            }            // Free the PIDL allocated by SHBrowseForFolder.
            pMalloc->Free(pidl);
        }
        // Release the shell's allocator.
        pMalloc->Release();
    }
