int num = Int32::Parse( textBox1->Text );

But be warned if textBox1->Text contains non-integer characters with will throw an expection so guard such code with an exception handler.

Edit: Realized we were talking about managed C++ not C#

num = atoi(textBox1->Text);

The atoi function converts a string to an integer.

It is in the standard C runtime libraries.

You need to include stdlib.h.
