Can anyone telme whats wrong in this part of code
- by Mobin
string name = ((DateTimePicker)sender).Name.ToString();
name = name.Substring(0, name.Length - 1);
name = name + "4";
TimeSpan duration = new TimeSpan();
duration = ((DateTimePicker)sender).Value - ((DateTimePicker)panel2.Controls[name]).Value;
name = name.Substring(0, name.Length - 1);
name = name + "6";
((MaskedTextBox)panel2.Controls[name]).Text = duration.ToString();
on execution it gives me Object reference not set to instance of an object
similar functionality is used on other places but can't find out what i have to reinitialize here :$
