Mappoint and VFP

does anybody help me to use the mappoint control in a VFP form.
When close the form I cannot close VFP an it appear the message cannot quit VFP

Can you deinstantiate or destroy the MapPoint object during the Form Close event?

PMFJI,
we had a similar problem and found that if you instantiate the Mappoint object and don't use it , it sometimes doesn't release properly resulting in the "cannot quit" message.

But I use the control; I close the map and I remove the object in the container...
... the result its the same "Cannot quit VFP"

There is a demo on using MapPoint and Foxpro:

Perhaps there are some pointers in there?

Did you ever see a solution for this? I get the same problem when I use the Mappoint ActiveX control (but not using automation, which is what the example by Fowler Software uses, so it does not apply).

We use MapPoint extensively in our VFP commercial applications and have found that the "cannot quit message" is usually related to object reference issues of one kind or another. We have also noted that in some cases you will need to issue "THIS.activemap.saved = .T." before the close of the map in order for it to release properly. You may also need to play with the VFP.AUTOYIELD parameter setting (depending on what you're doing).
Hope This Helps

Try putting the command

ON SHUTDOWN QUIT

near the top of the program code
