how to wait for an event?

Question

I have this problem with a Form : In the main class a create a Form and then show it: Global.f = new Formulario(); Application.Run(Global.f); in my form i have an event, when you press a button i call a method called "llamadas" where i have several calls to some methods. I can intercept those calls, so right after every execution i have this method: public override object Action(object target, object[] parameters) { //what i want to do here is modified the form showing the parameters of the method //and wait for the button "continue", then return the control here and execute the /method. return null; // execute the method } I can't use ShowDialog because it says the form is already visible. I would appreciate your suggestions. Thanks a lot.
