Re: How to define the input type in TextBox?

Dear David,

Thanks for you reply! I have following the book to write the program, it is
show follow;

-----------------------------------------------------------------------------------------------------------------------------------
 private: System::Void txtQty_TextChanged(System::Object^ sender,
System::EventArgs^ e) {
     int n500, n100, n50, n10, n1, amt, change;
     try
    {
     amt=txtPrice->Text->ToInt32(0)*txtQty->Text->Text->ToInt32(0);
     txtSum->Text=amt.ToString();
     txtChange->Text=(txtPay->Text->ToInt32(0)-amt).ToString();
     change=txtChange->Text->ToInt32(0);
     n500=change/500;
     change%=500;
     n100=change/100;
     change%=100;
     n50=change/50;
     change%=50;
     n10=change/10;
     change%=10;
     lbl500->Text=n500.ToString();
     lbl100->Text=n100.ToString();
     lbl50->Text=n50.ToString();
     lbl10->Text=n10.ToString();
     lbl1->Text=n1.ToString();
    }
     catch(Exception *err)
     {
      return;
     }
    }
-----------------------------------------------------------------------------------------------------------------------------------

ToInt32(0)<------ From book explain, it is a 32-bit Integer when I input the
number, but I can not run it on my computer.

The book is Visual C++ 2003. Can it running on Visual C++ 2008? If no,
please give my any suggestion!

Thanks!
Ricky
