Sorry ..I am nglish is not good. I am just learning c + +, I downloaded the visual studio 2010 When I create MFC project, compile time, the program prompts the project resource.h file is not created by the visual studio, When I open the resource.h view, we found, I change the MFC interface controls, resource.h not all statements of the control variables change. Still retained the way when it was established!!! What trouble you help me solve the problem. Thank you!!
