【代码备忘】MFC遍历文件夹、删除文件夹、CTreeCtrl使用方法

void CDirTraversal::FindDir(HTREEITEM pItem , const CString &dirPath )//HTREEITEM 为一个CtreeCtel节点，此处实现将文件夹映射到CtreeCtrl控件中去

{
CFileFind tempFind;
BOOL bFound = tempFind.FindFile(dirPath + "\\*.*");

if(pItem == NULL)

}
else
{
pItem2 = m_treeCtrl->InsertItem(dirPath.Right(dirPath.GetLength() - dirPath.ReverseFind('\\') - 1),0,1,pItem,TVI_LAST);//插入子节点
}
while(bFound)
{
bFound=tempFind.FindNextFile();
if(tempFind.IsDots())
continue;

tempFind.IsDirectory() ?
FindDir(pItem2,tempFind.GetFilePath()) : //找到的是文件夹
FindFile(pItem2,tempFind.GetFileName()); //找到的是文件
}
tempFind.Close();
