listbox used to display program status

[xzzy]

I have an app that uses a listbox to display program status messages, and a
public function to be used by the solution to update the listbox.

I do not know how to make the listbox public so it can be updated by that
function.
public class frmMain : System.Windows. Forms.Form{
public System.Windows. Forms.ListBox listBox1;
I would like to access the listbox to do something like this ( this code
does not work ):
public class ListboxOne{
public void AddMsg(string xMSG) {

PagingDN.frmMai n.listBox1.item s.add(PagingDN. frmMain.listBox 1.Items.Count,x M
SG);
if(PagingDN.frm Main.listBox1.I tems.Count>100) {
PagingDN.frmMai n.listBox1.Clea r();
}
}
}

you could try passing a reference to the listbox as shown below:

public class ListboxOne{
public void AddMsg(System.W indows.Forms.Li stBox listBox1,
string xMSG)
{

listBox1.items. add(listBox1.It ems.Count,xM
SG);
if(listBox1.Ite ms.Count>100){
listBox1.Clear( );
}
}
}

hope it helps :)

System.Windows. Forms.ListBox listBox1

of

public class ListboxOne{
public void AddMsg(System.W indows.Forms.Li stBox listBox1, string
xMSG) {

defines a listBox, but doesn't reference namespace.frmMa in.listBox1
