So I have including the files to my projects by simply : #include myheader.hpp and adding the headers into the solution explorer.But recently I have realized that I may omit the step of adding the headers to the solution explorer because it does not change anything. The only important fact is to define proper include directories in project properties. Am I missing something here ? Can someone clever explain this to me ? 
What is the purpose of including header files in the solution in Visual Studio?
c++;visual studio;headers
Mainly just to give you single click editing.The solution explorer doesn't effect the dependancy of the build/compiler.edit. Sometime's it's necessary if you need to 'compile' a header eg. a COM .idl or some Qt moc header file.
