if (IsFormAlreadyLoaded("frmTest") == true)
            { return; }

private bool IsFormAlreadyLoaded(string formToLoadName) //formToLoadName is the name of the form to be checked
{
    foreach (Form frmChild in this.MdiChildren)
        {
            if (frmChild.Name == formToLoadName)
            { frmChild.Activate(); return true; }
        }
            return false;
