You're trying to call instance method on class. Class is a type, instance is an object. Only static methods and properties are called on classes; static methods and properties are called on instances. The difference is: each instance method has implied (invisible) "this" parameter which gives access to instance data (and hence other instance methods and properties). You need to declare an object as a variable or create an object with gcnew to have an instance to call instance methods or properties.

I feel you need to step back to basics before you get to UI development.

Solution 2

Below are two examples on how to create an instance of your form2 class.

form2 ^myform = gcnew form2();
myform->Show();

or

(gcnew form2())->Show();
