Answer 1

string myType = "MyAssembly.MyType";

Assembly asm = Assembly.LoadFrom("MyAssembly.dll"); // creating instance by loading from other assembly
//Assembly asm = Assembly.GetExecutingAssembly();  // for creating instance from same assembly
//Assembly asm = Assembly.GetEntryAssembly(); // for creating instance from entry assembly
Type t = asm.GetType(myType);

Object obj = Activator.CreateInstance(t, null, null);

since it is a System.Windows.Form if u want to show the form u can do like

Form frm = obj as Form; // safely typecast
if (frm != null) // kewl it is of type Form
{
    //work with your form
    fmr.Show();
}

System.Reflection.Assembly.GetExecutingAssembly();
  Form frm = (Form)asm.CreateInstance("WindowsFormsApplication1.<string>");
  frm.Show();

add this to your code.
