Extra word appear in visual c++ output window

Everytime I compile and run a program, these extra 2 lines will appear in the beginning of the output window:

输入文件 0006E67C不存在

输入文件 00AB1514不存在开发者_开发问答

what should i do to clear it ? tq

On Google translate this is translated into:

0006E67C input file does not exist

00AB1514 input file does not exist

Do you have any files that are added to the project but does not exist on disk?
