How to Close() the MDIChild -during its Form_Load()

[Paraman]

Hi, I wish to close the MDI-Child Form during its Form_load(). Is it possible?

My Codes

private void Form_BooksMaster_Load(object sender, EventArgs e)
{
    if (MyDBConnector == false) {
        this.Parent = null;
        //this.Close();  ?? Error : Value Close() cannot be called while doing CreateHandle()
        //this.BeginInvoke(new MethodInvoker(this.Close)); ?? Error C3867 'System.Windows.Forms.Form.Close': non-standard syntax; use '&' to create a pointer to member
        return;   
    }
}

Thanks Again !
