C++.Net Open Window Form

[schwarem]

I have been forced to use C++ to create a GUI for an application. I normally use VB.Net or C#. I cannot open a form from the main form. Here is the code I am using.

frmNewScenario * NewScenario = new frmNewScenario();
NewScenario->ShowDialog();

It says frmNewScenario is an undeclared identifier. How do I get it to see my other form to recognize it as an identifier?
