An question about the compiling the new project?

[tjuwangli]

I want to add a new module into the VideoLanClient. So I make a new dll project in VC++6.0 in Win200. But when I compiled the project, it had 102 errors. So I compare the new project with other project. I found that the setting of the new source file(.c) was different from the other source file. In VC++6.0 I found that in the setting of the source file, it has an item named Preprocessor definitions ,It should be fill in the "WIN32,_DEBUG,_MBCS,_MT,_DLL,__VLC__,__PLUGIN__,MODULE_NAME=access_file,MODULE_NAME_IS_access_file" . Please tell me the meaning of this item.Thank you!!!
