Call Form2 property in main form(Form1)

Question

I have tried others suggestion for using this type and somehow manage to run it, but now I have using the same way but having an error as

Error :' FYP.Form6.listBox1' is inaccessible due to its protection level

I am enclosing code below

Form6 frm4 = new Form6(this.listbox1);

  for (int i=0;i<frm4.listBox1.Items.Count;i++)
  {
   // <P>
   xmlWriter.WriteStartElement("P");
   xmlWriter.WriteAttributeString("","DISP","",frm4.listBox1.Items[i].ToString());
   xmlWriter.WriteString(frm4.listBox2.Items[i].ToString());
   // </P>
   xmlWriter.WriteEndElement();
  }

Answer 1

My guess, the Modifiers property of listBox1 control of the Form6 form is set to 'private'. Up it to internal or public.

Answer 2

Thanx bro. I really appreciate it.
