Hi,

your first invoke of frmmater is nearly right.

C#

frmmaster obj_co = new frmmaster();

Your second piece of code makes no sense for me.

Usually you use a own dll-File like this. You have to declare your method public to use from outside.

in your dll:

C#

public class Calculator
{
        public double Add(double val1, double val2)
        {
            return val1 + val2;
        }
}

Usage of this dll in anyone Form:

C#

Calculator.Calculator calc = new Calculator.Calculator();
MessageBox.Show(calc.Add(9, 6).ToString());

Best Regards
