I am trying to serialize/deserialize a class (for the first time), and the serialization works fine, but as soon as I try to deserialize it, it gives me the exception:
System.Reflection.TargetInvocationException was unhandled
Message="Exception has been thrown by the target of an invocation."
Message="Member '' was not found."
at Trainer.BoostedClassifier..ctor(SerializationInfo info, StreamingContext context)
The class I'm serializing contains a List<int> type, could this be the source of the error?
I would appreciate any ideas to what this exception might be hinting at. (let me know if more info is needed)
You will have to either
1) Keep a reference to the original form and pass it to the new form when you create it, and before you hid the original.
2) hook into an event from the second form to the original form which causes the original to re-display itself.
The second is better practice as it doesn't require form2 to know anything outside itself - it just throws an "I'm done" event.
Niether is too complex, the second is a few extra lines of code.

OriginalGriff is Correct, if you want to edit the gridview in ASP.net, you must enable the appropriate properties that will show you the edit,Delete and update per row and if you click on Edit,you do not need to write a code to do that, ASP.NET already will do it for you. The Values will be Presented in a Textbox , and in edit more for you to edit and the Update and Cancel Button will be available options for you.

i have two forms
i want after 3 seconds the first form is hiden and the second one is appeared
sorry for that silly question but the first form has user control that playing a movie
i trying to use the usually code to hide the first one
it is not disappeared and the second is appeared
thanks very much
I believe Form1 is your start-up form. When Application.Run(new Form1()) is executed, it sets the Form1's visibility to true. This happens after your call to this.Hide() in Form1's constructor. This is the reason why first form is still visible.
Are you looking to implement a splash-screen? If yes, this is not the correct method. Try the following points
Show the Form1 before the call to Application.Run
Keep a timer on Form1 with interval as 3secs and when timer ticks, unload the form.
Instantiate Form2 and start message loop on that. Application.Run(new Form2()).
