opening a window form from another form programmatically

Question

I am making a Windows Forms application. I have a form. I want to open a new form at run time from the original form on a button click. And then close this new form (after 2,3 sec) programatically but from a thread other than gui main thread.

1. Can anybody guide me how to do it ?
2. Will the new form affect or hinder the things going on in the original main form ? (if yes than how to stop it ?)

Answer 1

To open from with button click please add the following code in the button event handler

var m = new Form1(); m.Show(); 

Here Form1 is the name of the form which you want to open.

Also to close the current form, you may use

this.close(); 

Answer 2

I would do it like this:

var form2 = new Form2(); form2.Show(); 

and to close current form I would use

this.Hide(); instead of

this.close();
