Problem with class and form

[Naumaan]

Form1.h:

private:

MyClass m_MyClass; // Member variable of Form1 class

Form1() // Constructor 
{
     m_MyClass = gcnew MyClass();

}
private: System::Void PlayBtn_Click(System::Object^ sender, System::EventArgs^ e) {
/*
call class method that increments value
m_MyClass->addVal();
*/
}

private: System::Void StopBtn_Click(System::Object^ sender, System::EventArgs^ e) {
/*
call class method that decrement value
m_MyClass->delVal();
*/
}
