Cmarkup生成、解析xml资料
【分享一下】 里面内容很多。。 觉得好就下吧 Cmarkup是依据EDOM的,这是这个简单XML分析的关键。EDOM是操作XML元素、属性和数据的简明方法集。当你不需要复杂的XML特性时,它避免你读大量的DOM和SAX文档。 如果你希望

Windows资源管理器(MFC)
MFC写的资源管理器,含注释 帖点代码片段出来 // 获取盘符到目录树,作为根目录下一级节点 void CwinResManagerDlg::GetLogicalDrives(HTREEITEM hRoot) { size_t szAllDrivesStrings = GetLogicalDriveStrings(0,NULL); //获取驱动器
字符
长度 char* pDriveStrings = new char[szAllDrivesStrings + sizeof(_T(""))]; //定义
字符
串存储驱动器
字符
pDriveStrings GetLogicalDriveStrings((DWORD)szAllDrivesStrings,pDriveStrings); //获取驱动器
字符
到pDriveStrings //截取单个驱动器
字符
出来添加到目录树上 //定义临时

指针指向驱动器

串方便,如果直接移动
字符
串指针,后面调用delete释放
字符
串资源的时候会报错) char* pTempDrive = pDriveStrings; size_t szDriveString = strlen(pTempDrive); while(szDriveString>0) { m_Tree.InsertItem(pTempDrive,hRoot); //加载解析后的一个驱动器信息到目录树 pTempDrive += szDriveString + 1; szDriveString = strlen(pTempDrive); } delete pDriveStrings; }
