item creates a new child window how do i make a checkmark appear when the
child form is loaded and have the checkmark dissapear when the childwindow
is closed? and how do i stop a child window from being created more than
once (if the user selects it more than once)?

Hi Blah,

I think you can create 2 public method in MainForm which functions are make
and cancel the checkmark of menuitem.
Then, in child form's load and closing event, you can invoke these 2 method.
Sample code snippet:

///////////////////////Main form//////////////////////////////////
//View->Source menuitem click event
private void showsource_Click(object sender, System.EventArgs e)
{
if(showsource.Checked==false)
{
Form2 f2=new Form2();
f2.MdiParent=this;
f2.Show();
}
}

public void open_childwnd()
{
this.showsource.Checked=true;
}

public void close_childwnd()
{
this.showsource.Checked=false;
}

//////////////////////child form/////////////////////////
private void Form2_Closing(object sender,
System.ComponentModel.CancelEventArgs e)
{
Form1 f=(Form1)this.MdiParent;
f.close_childwnd();
}

private void Form2_Load(object sender, System.EventArgs e)
{
Form1 f=(Form1)this.MdiParent;
f.open_childwnd();
}

It works well on my machine, if you still have anything unclear, please
feel free to tell me.
Have a nice day.
