Thread: DialogResult

ok I really dont get why this isnt working for me since I have read about 3 sites that say im doing it right

heres what ive got

Code:

private: System::Void openbut_Click(System::Object^  sender, System::EventArgs^  e) {
			if( openFileDialog1->ShowDialog() == DialogResult::OK )
			{
				openbox->Text = "Testing";
			}
		 }

I get these errors

Code:

error C2039: 'OK' : is not a member of 'System::Windows::Forms::Form::DialogResult'
error C2065: 'OK' : undeclared identifier

whats wrong here?
