fatal error C1010

Hi can anyone help me with my problrem. I am trying to make OCR system using neural networks. I am using classes made by other programmer.
I get the following error when including his classes to my project:

fatal error C1010: unexpected end of file while looking for precompiled header directive

The other programmer made these classes and used them as an example in a console application. This error happened when i tried to use these classes in a windows application.
If any one can help me please respond.
thanx in advance
bye.
