Its always better not to pass control instances across classes but just send string values as I mentioned before and use the string to display in the form..

I suppose you are calling this function from a form for displaying error... I would suggest you to return the error msg in the function and assing this to the label control in the form as you will have that use in that only but not in the class public string errRaise(string msg) { if (error == ) { error = msg; } return error;// I would like to write on a label1 on Form1 a msg. } and in form class you can have label1.Text = errRaise(ur msg);
