篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了安装包设计-------打包（MFC）---------知识总结相关的知识，希望对你有一定的参考价值。
目录：
1、选择文件夹
2、判断文件夹或文件是否存在
3、通过cmd命令行向程序中传递参数。
4、路径处理
5、文件夹以及文件的删除
6、复制文件
7、创建目录
8、从当前的应用程序中抽取资源
9、引用的别人的抽取等程序
10、压缩解压，引用别人的
11、添加资源到工程中
实现：
1、选择文件夹
CDirDialog dlg; dlg.SetWindowTitle(_T("选择待打包文件夹")); if(dlg.DoModal() == IDOK) { CString Path = dlg.GetPathname(); CString m_selectdir = Path; }
2、判断文件夹或文件是否存在
BOOL FolderExist(CString& strPath) //strPath 文件夹路径 { CString sCheckPath = strPath; if(sCheckPath.Right(1) != L"/") { sCheckPath += L"/"; } sCheckPath += L"*.*"; WIN32_FIND_DATA wfd; BOOL rValue = FALSE; HANDLE hFind = FindFirstFile(sCheckPath, &wfd); if ((hFind!=INVALID_HANDLE_VALUE) && (wfd.dwFileAttributes&FILE_ATTRIBUTE_DIRECTORY) ||(wfd.dwFileAttributes&FILE_ATTRIBUTE_ARCHIVE)) { //如果存在并类型是文件夹 rValue = TRUE; } FindClose(hFind); return rValue; }
3、通过cmd命令行向程序中传递参数
在命令行窗口输入： Package.exe 文件名 版本号
__argc = 3;
__argv[0]="Package.exe";__argv[1]="文件名";__argv[2]="版本号";
4、路径处理
在windows平台上获得的路径一般是这种形式：c:\\Test\\demo.exe,是以\\来区分目录级别，linux平台上是不能识别这种形式的路径，只能识别c:/Test/demo.exe，这一种形式，windows也识别这种形式。所以在以后的路径处理上要使用c:/Test/demo.exe这种形式。
5、文件夹以及文件的删除
CFile::Remove(LPCTSTR lpszFileName, CAtlTransactionManager* pTM) 删除单个文件，但在实际过程中需要删除当前目录以及目录下的所有文件。
bool MyDeleteFile(CString &Path) { SHFILEOPSTRUCT FileOp={0}; FileOp.fFlags = FOF_ALLOWUNDO | //允许放回回收站 FOF_NOCONFIRMATION; //不出现确认对话框 FileOp.pFrom = Path; FileOp.pTo = NULL; //一定要是NULL FileOp.wFunc = FO_DELETE; //删除操作 return SHFileOperation(&FileOp) == 0; }
6、复制文件
CopyFile(LPCTSTR lpExistingFileName,LPCTSTR lpNewFileName,BOOL bFailIfExists) bFailIfExists=false时，如果文件已经存在则覆盖文件。
7、创建目录
bool CreateDir(CString strPath) { char* temp=strPath.GetBuffer(strPath.GetLength()); std::string Directoryname = temp; if (Directoryname[Directoryname.length() - 1] != \'\\\\\') { Directoryname.append(1, \'\\\\\'); } std::vector< std::string> vpath; std::string strtemp; BOOL bSuccess = FALSE; for (int i = 0; i < Directoryname.length(); i++) { if ( Directoryname[i] != \'\\\\\') { strtemp.append(1,Directoryname[i]); } else { vpath.push_back(strtemp); strtemp.append(1, \'\\\\\'); } } std::vector<std::string>:: const_iterator vIter; for (vIter = vpath.begin();vIter != vpath.end(); vIter++) { bSuccess = CreateDirectory(vIter->c_str(), NULL) ? TRUE :FALSE; } return true; }
8、从当前的应用程序中抽取资源
bool GetResourceFromLocal(CString &DesPath) { //从本地应用获得资源文件.zip CString tempPathPro = DesPath + "/" + "Resource.zip"; //输出路径 HRSRC hrSrc = FindResource(AfxGetResourceHandle(), MAKEINTRESOURCE(IDR_AFX_RESOURCE), "AFX_RESOURCE"); if(hrSrc == NULL) { return false; } HGLOBAL hGlobal = LoadResource(AfxGetResourceHandle(), hrSrc); if(hGlobal == NULL) { return false; } LPVOID lpExe = LockResource(hGlobal); if(lpExe == NULL) { return false; } CFile file; if(!file.Open(tempPathPro, CFile::modeCreate | CFile::modeWrite)) { return false; } else { file.Write(lpExe, (UINT)SizeofResource(AfxGetResourceHandle(), hrSrc)); file.Close(); } return true; }
9、引用的别人的抽取等程序
