STL (standard template library STL) is a general term for a series of software developed by the HP lab. It was developed by Alexander Stepanov, Meng Lee, and David R musser while working at the HP lab. Although it mainly appears in C ++, this technology has existed for a long time before it was introduced into C ++. STL code is broadly divided into three types: algorithm (algorithm), container (container), and iterator (iterator ), almost all code uses the template class and template function, w

The code is as follows, if L is displayed, the left button is pressed, the R is displayed, the right button is

　　ATL can be used as a complete control development framework. Its main goal is to provide convenient development methods and generate smaller target files. Because ATL can be removed from MFC, its execution speed and loading speed are faster than those developed by MFC. Of course, you can also use MFC in ATL, but this will lose the advantages of

M_pfncreateinstance (punkouter, riid, ppvobj); now everything is clear, The layer-by-layer packaging of ATL for creating class factories has been opened, and the rest of the process for creating components is already We are very familiar with the process! However, we still need to query an iunknown pointer for the class factory object. We can see in the previous pentry-> PCF. 6: stdmethod (QueryInterface) (refiid IID, void ** ppvobject){Return _ int
