В каком это смысле?? 
Так, как ты написал, тоже пробовал - ошибка! Решение нашел все-же в гугле, но вот по этой ссылке: http://social.msdn.microsoft.com/Forums/eu/Vsexpressinstall/thread/c97c2d37-c56a-4213-a889-4cc9e2ca259c

Hi I'm working with C++ Express, I'm new to Windows Forms and the namespaces used but not to C++. I'm having difficulties with DialogResults:
The MSDN documentation gives examples like this:
System::Windows::Forms::DialogResult result;
result = MessageBox::Show( this, message, caption, buttons );
if ( result == ::DialogResult::Yes )
Yet when I compile I get the following errors (for the if line) :
error C3083: 'DialogResult': the symbol to the left of a '::' must be a type
error C2039: 'Yes' : is not a member of '`global namespace''
error C2065: 'Yes' : undeclared identifier
So I also try without the leading :: and get:
error C2039: 'Yes' : is not a member of 'System::Windows::Forms::Form::DialogResult'
see declaration of 'System::Windows::Forms::Form::DialogResult'
error C2065: 'Yes' : undeclared identifier
Finally I try with the whole namespace (is that the right terminology ?) and it compiles:
if (result == System::Windows::Forms::DialogResult::Yes )

Make sure you have both the #using and the using namespace directives to ensure the compiler understands your references.
For example -
#using <System.DLL>
#using <System.Drawing.DLL>
#using <System.Windows.Forms.DLL>
using namespace System;
using namespace System::Drawing;
using namespace System::Windows::Forms;
