1. 选中一个文件夹
程序源码：
/*关键头文件*/
#include <shlobj.h>
#include <atlstr.h>string SelectSingleDirectory()
{CString strPath(_T(""));BROWSEINFO bi;bi.hwndOwner = NULL;bi.pidlRoot = CSIDL_DESKTOP; //文件夹的根目录，此处为桌面bi.pszDisplayName = NULL;bi.lpszTitle = _T("请选择一个文件夹"); //显示位于对话框左上部的提示信息bi.ulFlags = BIF_DONTGOBELOWDOMAIN | BIF_RETURNONLYFSDIRS | BIF_NEWDIALOGSTYLE; //有新建文件夹按钮bi.lpfn = NULL;bi.iImage = 0;LPITEMIDLIST pidl = SHBrowseForFolder(&bi); //调用选择对话框if (pidl == NULL){std::cout << "You havn't chosen any file!" << std::endl;return string(CW2A(strPath.GetBuffer()));}TCHAR strFolder[1024];SHGetPathFromIDList(pidl, strFolder);strPath = strFolder;return string(CW2A(strPath.GetBuffer()));
}使用说明：

2.选中一个文件
程序源码：
/*关键头文件*/
#include <atlstr.h>std::string SelectSingleFile()
{std::string res = "";TCHAR tmp[MAX_PATH] = { 0 };GetCurrentDirectory(MAX_PATH, tmp); //取出当前的工作目录，保存到临时变量tmp中TCHAR szBuffer[MAX_PATH] = { 0 };OPENFILENAME ofn = { 0 };ofn.lStructSize = sizeof(ofn);ofn.hwndOwner = NULL;ofn.lpstrFilter = _T(" *.flt\0*.flt\0 *.osg\0*.osg\0 *.ive\0*.ive\0 All Files(*.*)\0*.*\0"); //要选择的文件后缀 ofn.lpstrInitialDir = _T("F:\\Program\\Creator_flt\\"); //默认的文件路径 ofn.lpstrFile = szBuffer; //存放文件的缓冲区ofn.nMaxFile = sizeof(szBuffer) / sizeof(*szBuffer);ofn.nFilterIndex = 0;ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST | OFN_EXPLORER; //标志如果是多选要加上OFN_ALLOWMULTISELECTif (GetOpenFileName(&ofn) == 1){res = CW2A(ofn.lpstrFile); //将宽字符集（Unicode）转化为多字符集（ASCII）SetCurrentDirectory(tmp); //将tmp中的工作目录恢复，不恢复的后果就是程序运行的默认workspace将变成你刚选择的文件所在的目录下！！}else{std::cout << "You havn't chosen any file!" << std::endl;}return res;

3.选中多个文件
程序源码：
/*关键头文件*/
#include <atlstr.h>vector<string> SelectMultiFiles()
{TCHAR* iter = NULL;OPENFILENAME ofn = { 0 };TCHAR szDirectory[MAX_PATH] = {0}; //存放解析出的目录TCHAR szBuffer[80 * MAX_PATH] = {0}; //在此设置最大支持的文件数vector<string> res; //存放结果ofn.lStructSize = sizeof(ofn);ofn.hwndOwner = NULL;ofn.lpstrFilter = _T("All Files(*.*)\0*.*\0"); //要选择的文件后缀 ofn.lpstrInitialDir = _T("F:\\Program\\Creator_flt\\"); //默认的文件路径 ofn.lpstrFile = szBuffer; //存放文件的缓冲区ofn.nMaxFile = sizeof(szBuffer) / sizeof(*szBuffer);ofn.nFilterIndex = 0;ofn.Flags = OFN_EXPLORER | OFN_ALLOWMULTISELECT;if (GetOpenFileName(&ofn) == 1){lstrcpyn(szDirectory, szBuffer, ofn.nFileOffset);lstrcat(szDirectory, _T("\\"));iter = szBuffer + ofn.nFileOffset; //把指针指向第一个文件while(*iter){CString path = szDirectory;path += iter;string tmpPath = CW2A(path.GetBuffer());res.push_back(tmpPath);iter += (lstrlen(iter) + 1); //移至下一个文件}}else{std::cout << "You havn't chosen any file!" << std::endl;}return res;

4.查找文件夹下指定格式的文件
程序源码：
/*关键头文件*/
#include <io.h>vector<string> findFilesFrom(string directory)
{directory += '\\';string fileName;vector<string> res;struct _finddata_t fileInfo;string targetFormat = directory + "*.cpp"; //目标格式long findHandle = _findfirst(targetFormat.c_str(), &fileInfo);if (findHandle == -1){cout << "There dont have any target format files existed!" << endl;_findclose(findHandle);return res;}do{fileName = directory + fileInfo.name;if (fileInfo.attrib == _A_ARCH){res.push_back(fileName);}} while (_findnext(findHandle, &fileInfo) == 0);_findclose(findHandle);return res;
}
