VC：遍历文件夹下所有文件和文件夹（CFileFind类、树视图控件、图像链表、HTREEITEM句柄、TV_INSERTSTRUCT 结构体）

1、添加变量：

       HTREEITEM hDad;

       HICON hIcon;

       TV_INSERTSTRUCT tvinsert;

       CImageList m_imagelist;

2、OnInitDialog()中初始化：

       // TODO: Add extra initialization here

       m_imagelist.Create(16,16,0,8,8);

       hIcon=AfxGetApp()->LoadIcon(IDI_ICON1);

       m_imagelist.Add(hIcon);

       CTreeCtrl * pTree=(CTreeCtrl *)GetDlgItem(IDC_TREE);

       pTree->SetImageList(&m_imagelist,TVSIL_NORMAL);

       //开始显示树视图控件

       tvinsert.hParent=NULL;

       tvinsert.hInsertAfter=TVI_LAST;

       tvinsert.item.mask=TVIF_IMAGE|TVIF_SELECTEDIMAGE|TVIF_TEXT;

       tvinsert.item.hItem=NULL;

       tvinsert.item.state=0;

       tvinsert.item.stateMask=0;

       tvinsert.item.cchTextMax=6;

       tvinsert.item.iSelectedImage=1;

       tvinsert.item.lParam=0;

       //显示第一层

       tvinsert.item.pszText="D:\\VC";

       tvinsert.item.iImage=0;

       tvinsert.item.iSelectedImage=0;

       hDad=pTree->InsertItem(&tvinsert);

       CString filepath="D:\\VC\\*.*";

       //调用自定义函数：

       Findfile(filepath,hDad);

3、添加自定义函数：

void CFileFindDlg::Findfile(CString str, HTREEITEM h)

{

       CTreeCtrl * pTree=(CTreeCtrl *)GetDlgItem(IDC_TREE);

       CFileFind filefind;

       CString filepath=str;

       CString filename;

       tvinsert.hParent=h;

       tvinsert.item.iImage=0;

       tvinsert.item.iSelectedImage=0;

       BOOL flag=filefind.FindFile(filepath);

       while(flag)

       {

              flag=filefind.FindNextFile();

              if(filefind.IsDots())

              {

                     continue;

              }

              else

              {

                     if(filefind.IsDirectory())

                     {

                            filename=filefind.GetFileName();

                            tvinsert.item.pszText=strdup(filename);

                            tvinsert.hParent=h;

                            hDad=pTree->InsertItem(&tvinsert);

                            Findfile(filefind.GetFilePath()+"\\*.*",hDad);//递归查找文件

                     }

                     else

                     {

                            tvinsert.hParent=h;

                            filename=filefind.GetFileName();

                            tvinsert.item.pszText=strdup(filename);

                            pTree->InsertItem(&tvinsert);

                     }

              }

       }

}
