MFC 目录选取，指定类型文件查找复制

目录选取：

BROWSEINFO bi;

ZeroMemory(&bi, sizeof(BROWSEINFO));

bi.hwndOwner = m_hWnd;

bi.ulFlags = BIF_RETURNONLYFSDIRS;

bi.lpszTitle = _T("Browse A Input Path");

LPITEMIDLIST pidl = SHBrowseForFolder(&bi);

BOOL bRet = FALSE;

TCHAR szFolder[MAX_PATH*2];

szFolder[0] = _T('/0');

if (pidl)

{

bRet = TRUE;

IMalloc *pMalloc = NULL;

if (SUCCEEDED(SHGetMalloc(&pMalloc)) && pMalloc)

{

pMalloc->Free(pidl);

pMalloc->Release();

}

}

if(bRet)

{

m_strInputPath = szFolder;//选择的文件夹路径

SetDlgItemText(IDC_EINPUT,m_strInputPath);

递归查找指定类型的文件：

}

else

//MessageBox(strDstFileName);

if(0 == strCurrFileExt.Compare(strExt))

//MessageBox(str);

//复制该文件

PathFileExists的头文件和库：
