Wt

Visual Studio 2012's compiler gives this performance related warning.

warning C4800: ' *const ' : forcing value to bool 'true' or 'false' (performance warning)

C:\Users\hp\WtCommunityCMS\src\Wt/Dbo/ptr(335) : while compiling class template member function 'bool Wt::Dbo::MetaDbo::isLoaded(void) const'

It's nothing serious, just annoying. You can use this line instead.

bool isLoaded() const { return obj_ != 0; }
