C++/CLI - how to open a new form and back

Question

I am creating an application where the front end has to be a Windows Form using C++/CLI. The form is used for login purpose.

In my form, I have a register button. On

Answer 1

Create a constructor for RegisterForm which accepts a System::Windows::Form ^ object, and pass this to it when you are instantiating it from within the login form class

Form^ rgForm = gcnew RegisterForm(this);
rgForm->Show();
this->Hide();

Assume the login form object is called otherform within the RegisterForm class. Once you're ready to bring it back, just call otherform->Show()

When you hide the form, it still exists, it is just not visible to the user.

EDIT: I got this to work just fine. Here are the modifications (not the full code) that I made to the form

Form2(Registration form)

Form2(System::Windows::Forms::Form ^ frm1)
    {
        otherform = frm1;
        InitializeComponent();

    }

private: System::Windows::Forms::Form ^ otherform;

private: System::Void Cancel_Click(System::Object^  sender, System::EventArgs^  e) {
             this->Hide();
             otherform->Show();

}

Form1(Login form)

#include "Form2.h"

private: System::Void Register_Click(System::Object^  sender, System::EventArgs^  e) {

             Form2 ^ frm2 = gcnew Form2(this);
             frm2->Show();
             this->Hide();
}
