It is very difficult to answer such a question without seing Your 
code so please show the code You are using. 
There is nothing in the code I wrote that gives that exception.

But if You are doing something with visible as responce to that
message You need to make sure that the form is finished creating.

You can set a bool in the form show event and then chek it in 
the message or You can check the ComponentState to make sure that
the form is created.
You can also check the Parent property if that is NULL don't 
do anything.

if You want to adjust the size or pos of the form You shuld chage 
the the values in the WINDOWPOS structure and not use the properties 
of the form.

Kind regards
Asger
