Exterior Door Handle Broke Off on 1999 BMW 740iL

My driver's side exterior door handle broke off. I have a 1999 BMW 740iL and I would like to know what I should do to fix it. Can I use glue or can I weld it back on? Also, can someone tell me where I can find the part for the exterior side door handle? I need detailed instructions on how I can fix this.

You will have to get a new door handle from BMW. Once they break, that is it. You will have to remove the inner door panel, with the window in the up position, in order to replace the handle. If you do not have experience with this type of vehicle, I would by the part and have a good German car shop install it, this car is very sophisticated, ( there is a computer for each door ), and you can really do come damage if you don't know EXACTLY what to do.
You may also have to reprogram the door lock adaption once you have put int the new door handle, a German car shop can do this with the GT1 which is the $40K+ scanner for BMWs.
