MFC 打开保存文件对话框

一、打开文件夹： 1、CFileDialog实现 CFileDialog hFileDlg(TRUE,NULL,NULL,OFN_FILEMUSTEXIST|OFN_PATHMUSTEXIST|OFN_READONLY,        TEXT("支持的图像文件 (*.jpg;*.gif;*.bmp;...)|*.jpg;*.gif;*.bmp|专用Tiff图像文件(*.tiff;*.tif)|*.tiff;*.tif|所有文件(*.*)|*.*||"),NULL); hFileDlg.m_ofn.nFilterIndex=1; hFileDlg.m_ofn.hwndOwner=m_hWnd; hFileDlg.m_ofn.lStructSize=sizeof(OPENFILENAME); hFileDlg.m_ofn.lpstrTitle=TEXT("打开图像文件...\0"); hFileDlg.m_ofn.nMaxFile=MAX_PATH; if(hFileDlg.DoModal() == IDOK) { m_path = hFileDlg.GetPathName(); UpdateData(FALSE); } 2、API实现 OPENFILENAMEA ofn;       char szFile[260];      ZeroMemory(&ofn, sizeof(ofn)); ofn.lStructSize       = sizeof(ofn); ofn.hwndOwner         = NULL; ofn.lpstrFile         = szFile; ofn.lpstrFile[0]      = '\0'; ofn.nMaxFile          = sizeof(szFile); ofn.lpstrFilter       = "音频文件\0*.wma\0"; ofn.nFilterIndex      = 1; ofn.lpstrFileTitle    = NULL; ofn.nMaxFileTitle     = 0; ofn.lpstrInitialDir   = NULL; ofn.Flags = 0; if (GetOpenFileNameA(&ofn)==FALSE) { return S_FALSE; } CString c_save_path=ofn.lpstrFile; 二、保存文件 同上，只不过将 CFileDialog hFileDlg(true,NULL 改为 CFileDialog hFileDlg(false,NULL， 或者将GetOpenFileNameA改为GetSaveFileNameA，即可。 三、浏览文件夹对话框 //回调函数 int CALLBACK BrowseCallbackProc(HWND hwnd, UINT uMsg, LPARAM lParam, LPARAM lpData) { if(uMsg==BFFM_SELCHANGED||uMsg==BFFM_INITIALIZED) {      if(uMsg==BFFM_INITIALIZED)      {        ::SendMessage(hwnd,BFFM_SETSELECTION,TRUE,LPARAM(lpData));      } } return 0; } TCHAR chPath[255]; //用来存储路径的字符串 CString strPath     = ""; BROWSEINFO bInfo; GetModuleFileName(NULL,chPath,MAX_PATH); strPath             =chPath; ZeroMemory(&bInfo, sizeof(bInfo)); bInfo.hwndOwner     = m_hWnd; bInfo.lpszTitle     = _T("请选择路径: ");     bInfo.ulFlags       = BIF_RETURNONLYFSDIRS|BIF_EDITBOX; bInfo.lpfn          = BrowseCallbackProc; bInfo.lParam        = (LPARAM)strPath.GetBuffer(strPath.GetLength()); LPITEMIDLIST lpDlist; //用来保存返回信息的IDList lpDlist = SHBrowseForFolder(&bInfo) ; //显示选择对话框 if(lpDlist != NULL) //用户按了确定按钮 { SHGetPathFromIDList(lpDlist, chPath);//把项目标识列表转化成字符串 strPath = chPath; //将TCHAR类型的字符串转换为CString类型的字符串 m_save_path=strPath; UpdateData(FALSE); } 设置对话框的标题：  dlg.m_ofn.lpstrTitle = _T("Open Image"); http://topic.csdn.net/u/20090306/17/d5b0bac7-8349-400d-a463-ee88d7da71cc.html
