Hi, all. Please, Help me. Its very important for me. I try to output a variable, type string, in TextBox. I tried everything that I could. But always the mistake. And i show you a file Form1.h in which i have got a problem.

That's my project

Code:
private: System::Void button20_Click(System::Object^  sender, System::EventArgs^  e)
        {
        adding();
        textBox1->Text = b.ToString();
  

        }

Code:
void adding()
{
  b = (textBox1.Text).ToString();
// b = (richTextBox1->Text).ToString();

/*CLargeNumber oLN1 = CLargeNumber(1000000);
oLN1 -= CLargeNumber(2000000);
cout << "Answer " << cout << oLN1.ToString() << endl;
system("pause");*/
 
//Testing the LargeNumber class
CLargeNumber oLN1(a);
CLargeNumber oLN2(B);
b=(oLN1+oLN2).ToString();
}
