6 IntelliSense: a value of type "void" cannot be used to initialize an entity of type "int" d:\c++\ugs\common\connection.cpp 18
7 IntelliSense: the #endif for this directive is missing d:\c++\ugs\common\connection.h 1
8 IntelliSense: this declaration has no storage class or type specifier d:\c++\ugs\common\connection.h 26whats wrong and how can i fix it thanks
i appreciate it.
