System.AccessViolationException was unhandled

Question

Hi,

My C# app throws the following exception:

System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

1. static void Main()
2.         {
3.             Application.EnableVisualStyles();
4.             Application.SetCompatibleTextRenderingDefault(false);          
5.             Application.Run(new Login());  // get exception at this line(wen i try to enter details in text box)        
6.  
7.         }

The stack trace is as follows :
