1.打开文件GetOpenFileName

OPENFILENAME ofn;WCHAR szFile[100];ZeroMemory(&ofn, sizeof(ofn));ofn.lStructSize = sizeof (ofn);ofn.hwndOwner = NULL;ofn.lpstrFile = szFile;ofn.lpstrFile[0] = '\0';ofn.nMaxFile = sizeof(szFile);ofn.lpstrFilter = L"文件夹\0*.*\0";ofn.nFilterIndex = 1;ofn.lpstrFileTitle = NULL;ofn.nMaxFileTitle = 0;ofn.lpstrInitialDir = NULL;ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;if (GetOpenFileName(&ofn))<span style="white-space:pre"></span>{//todo ofn.lpstrFile}

2.保存文件GetSaveFileNam

 OPENFILENAME ofn = { OPENFILENAME_SIZE_VERSION_400 };//or  {sizeof (OPENFILENAME)}     ofn.hwndOwner =GetForegroundWindow();// 打开OR保存文件对话框的父窗口   ofn.lpstrFilter = TEXT(""All\0*.*\0Text\0*.TXT\0");    //过滤器 如果为 NULL 不使用过滤器   lstrcpy(szPathName, TEXT(""));   ofn.lpstrFile = szPathName;   ofn.nMaxFile = sizeof(szPathName); ofn.lpstrTitle = TEXT("选择文件"); TCHAR szCurDir[MAX_PATH];   GetCurrentDirectory(sizeof(szCurDir),szCurDir);   ofn.lpstrInitialDir=szCurDir;//设置对话框显示的初始目录   ofn.Flags = OFN_EXPLORER |OFN_ALLOWMULTISELECT| OFN_FILEMUSTEXIST;//如果需要选择多个文件 则必须带有  OFN_ALLOWMULTISELECT标志  BOOL bOk = GetSaveFileName(&ofn); if (bOk)   {    CString strFile = _T("");  strFile.Format(_T("Save file %s"),szPathName);    MessageBox(strFile); }

3.浏览文件夹SHBrowseForFolder

#include <ShlObj.h>//必须包含此头文件 TCHAR szPathName[MAX_PATH];  BROWSEINFO bInfo={0};   bInfo.hwndOwner=GetForegroundWindow();//父窗口   bInfo.lpszTitle=TEXT("浏览文件夹");   bInfo.ulFlags=BIF_RETURNONLYFSDIRS |BIF_USENEWUI/*包含一个编辑框 用户可以手动填写路径 对话框可以调整大小之类的..*/|    BIF_UAHINT/*带TIPS提示*/ |BIF_NONEWFOLDERBUTTON /*不带新建文件夹按钮*/;    LPITEMIDLIST lpDlist;   lpDlist=SHBrowseForFolder(&bInfo);   if (lpDlist!=NULL) {    SHGetPathFromIDList(lpDlist,szPathName);   CString strFile = _T("");  strFile.Format(_T("Select path %s/n"),szPathName);    MessageBox(strFile); }
