Passing data between class and form in C # using delegate parameter
I need to pass a value to RichTextBox from a class. Here is my code. I have to pass values to any tools like textbox, list, but I don't know how. I have to use delegates to pass the md value to both methods and to the same richtextbox.
namespace delegateEx2
{
public class MyClass : Form1
{
delegate void MyDelegate(string MyString);
public void ShowThoseMessages()
{
MyDelegate md = new MyDelegate(log1);
md += log2;
md("Error Log Text");
}
public void log1(string message) {
//what can I write here to pass the md into the RichTextBox on Form1.cs
//I tried something like Systems.Windows.Form.rtxblog but did not work
//......................................
}
public void log2(string message2)
{
//.....................................
}
}

I should have seen this before. Here is some sample code ...
TheClass.cs
using System.Windows.Forms;
...
public bool validateForm(TextBox txtTitle, TextBox txtPath, CheckedListBox ckList)
{
bool title = false;
bool path = false;
if (txtTitle.Text == String.Empty)
{
title = false;
txtTitle.Text = "Title is empty!";
paintred(txtTitle);
} else { title = true; paintwhite(txtTitle); }
if (txtPath.Text == String.Empty)
{
path = false;
txtPath.Text = "Path is empty!";
paintred(txtPath);
} else { path = true; paintwhite(txtPath); }
bool ckItem1 = ckList.GetItemChecked(0);
bool ckItem2 = ckList.GetItemChecked(1);
bool ckItem3 = ckList.GetItemChecked(2);
bool ckItem4 = ckList.GetItemChecked(3);
bool ckItem5 = ckList.GetItemChecked(4);
if (title && path && ckItem1 && ckItem2
&& ckItem3 && ckItem4 &&
ckItem5 )
return true;
else
return false;
}
Then in my form I ...
if (TheClass.validateForm(txtBox, txtBox2, listCheckList))
{
txtBox3.Text = TheClass.generateItem1(something, something2);
txtBox4.Text = TheClass.generateItem2(something, something2, txtPath.Text, txtTitle.Text, listCheckList.GetItemChecked(5));
}
else
{
MessageBox.Show("Please check fields marked in red, if any. Double check your Check List required items.", "Title Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
