then directly double-click the exe file. A window came out! What's the difference? There is no difference in running, but we know that this window is implemented in this DLL! We want to add a button to the window? No problem, just add it! After the addition of a new DLL, copy to the Exe folder overwrite the old, the modification is complete! We don't need to modify this exe.This time we recall that when we use the DLL we created, is it the same as using QtGui.dll? Only QtGui.dll has been placed

Link: https://code.google.com/p/nll/ NLL is a multi-platform the open source project entirely written in C + +. Its goal are to propose generic and efficient algorithms for machine learning and more specifically computer. It is intended to being very easy to integrate and it are mainly composed of header files with no dependency on any library bu t the STL. Architecture NLL implements generic algorithms usi

iOS Learning: Common third-party libraries (Gdataxmlnode:xml parsing library)Parsing XML usually has two ways, DOM and SAX:When the DOM parses the XML , it reads into the entire XML document and constructs a tree structure (node tree) that resides in memory, which can be retrieved from any XML node by traversing the tree structure to read its properties and values. And, in general, you can query XML nodes d

It's been a while since I've been learning and using the boost library for a while, and the boost has been a great convenience for my daily development, and it's made me more reliant on the boost library. But the boost function is too much, every use still has to look over the previousInformation, so in order to later can be more convenient to use, in this genera
