There was a problem sending the command to the program

[georgesOne]

Hi All,
I have constructed a hierarchical access database with a form containing the treeview control. The application (DAO)worked fine for months, but from one day to the other (and possibly I have checked some code with ADO in a different database), the Access window closes followed by the above error message: 'There was a problem sending the command to the program.' The record locking information remains and need to be (and can be) deleted.
I checked the code, and obviously when it comes to characterizing and populating the treeview control this fatal error happens. The application can not be used anymore.
This happens for the first time in occasional VB programming over several years.
Looks like I have to construct the form again, or does anybody have a better = less work-intensive tip?
Thanks, georges

On a similar error in Excel, the fix was to go to Tools/Options/Advanced and check "Ignore DDE requests", see if playing with that fixes it, since it seems to be something that is being switched on and off, it may be some software changes are switching those options.
