Where are you initializing frm?

Also make sure that your parent form has MdiContainer = True

the sequence of my code is like this :
private void InitializeComponent()
{ ...
this.IsMdiContainer = true; // it is
already exists
....}

Form1 frm = new Form1(); //here frm is created
frmAlarmBox AlarmBox = new frmAlarmBox();
TcpIpConnection TCPListen;
bool blnAlarmState = false;

private void frmMdiMain_Load(object sender, System.EventArgs e)
{
frm.MdiParent = this;
frm.Show();
}

static void Main()
{
Application.Run(new frmMdiMain ());
}
