0	Hi "frm" is ambiguous Because for all the three forms(FORM1, FORM2, FORM3) you are creating the same object name(frm) at that point of time if u call frm.message function(frm.message()) it will be ambiguous ------------------------------------------------ Learn throughout life Naraayanan, if this helps please login to Mark As Answer. \| Alert Moderator

Hi,
Yes , This is my error "Object reference not set to an instance of an object."

I tried the following code when form3 button event.But form1 will display one more time.

 Form1 frm1 = new Form1();

            frm1.Show();

I just show the form1.so form1 displays.

 Form1 frm1 = new Form1();

            frm1.message();

I just try the above code.It will get "Object reference not set to an instance of an object." .So How to do this?Please give me a solution .
