Why do i get a System.NullReferenceException?
Good Day,
I have a dll that disables/enables the keyboard using the SetWindowsHookEx, CallNextHookEx and UnhookWindowsHookEx api's. Now when i run my program, at first it does what its suppose to do, for about 2 minutes more or less, my apllication will generate this error:
/*
An unhandled exception of type 'System.NullReferenceException' occurred in system.windows.forms.dll
Additional information: Object reference not set to an instance of an object.
*/
The error points to this part of my code:
static void Main()
{
try
{
Application.Run(new Form1());
}
catch(Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message); <------------- error
}
}
Does this have anything to do with garbage collection?
