Hi,

I have 2 WinForms for my MDI app. One is ParentForm; another is 
ChildForm. Below is part of my code in the ParentForm. What I 
am trying to do is that after clicking NewChild menu item, 
check if any Child instance is created. If so, bring the 
existing Child to front. If not, create a new Child instance. 
But the problem is when I click Close menu item to close the 
Child, it is never closed. 

*********************************
private frmChild g_objfrmChild;

//Event when click the NewChild Menu item
private void miNewChild_Click(object sender, System.EventArgs e)
{
  frmChild objfrmChild = GetfrmChildInstance();
  objfrmChild.MdiParent = this;
  objfrmChild.Show();
  objfrmChild.BringToFront();
}

//Check if any Child instance is created
public frmChild GetfrmChildInstance()
{
  if (this.g_objfrmChild == null)
  {
    //if not created yet, Create an instance
    this.g_objfrmChild = new frmChild();
  }

  return this.g_objfrmChild;
}

//Event when click Close menu item
private void miClose_Click(object sender, System.EventArgs e)
{
  if(this.ActiveMdiChild.Name == "frmChild")
  {
    this.g_objfrmChild.Close();
  }
}
*******************************************************

Thanks in advance,
Peter
