it sounds like you've got a good start... this is roughly what I would do... private void GenerateStatement_Click(object sender, EventArgs e) { formGenerateStatement tmpfrm = new formGenerateStatement(Account a); tmpfrm.Show(); } then on your GenerateStatement form, create a constructor that takes the Account object as a param.

i have to do a credit card application. I have a abstract class Account which is inherited by a RegularAccount, SilverAccount... etc, and its methods are overriden by coresponding methods in the child classes, the new objects are created by clicking a AddAccount button. By clicking a button in lets say GenerateStatement, I want to open a new form which displays account information(balance, payments..etc). How can I pass the attributes of the newly created object to the form. TY , I really apreaciate your help.

That would violate the rules of object oriented programming, you need to design your forms (which are objects themselved) to stand alone, and any resources that they need should be passed in as parameters in the constructor, or set as properties. you really want to stay away from trying to implement the equivilant to global variables in an object oriented language.
