private void addNewVendorToolStripMenuItem_Click(object sender, EventArgs e)
{

        Vendor frm = new Vendor();
        frm.MdiParent = this;
        frm.Show();
      
    }

    private void purchaseToolStripMenuItem1\_Click(object sender, EventArgs e)
    {
        Purchase frm = new Purchase();
        frm.MdiParent = this;
        frm.Show();

    }

Before "frm.Show();", add "this.Hide();" Unless you are looking for a modal window that blocks the old window,then I think you change "frm.Show();" to "frm.ShowModal();"

Opacity, the new Transparency.
