hi all,

im creating a windows application in C#.net.in that,

im having form1 with listbox.

im calling form2 from form1.

in form2 i want to populate the list box of form1 and activate form1


(if i use
form1 fn=new form1();
fn.show();
---> it creates a new instance of form1.that i dont want.i want to populate the listbox of already existing form1 and activate that form)
(ie)i want to access the parent form1 from child form2.

There is no "already existing" form1 in C# like there was in VB6. You always need to create an instance of a form before using it.

However, once instantiated you can hold the reference to that form, and use it when and as needed. Displaying it and hiding it as needed.
