>It works only in VFP environment. I want to make a tool like dbu, that i can modify database on my client pc.

Sorry you're right for a moment I mixed that with modi structure.
dbu is like more 'modi stru' as I remember, isn't it ?
You can't use 'modify database' in exe but a DBC could be build or altered from top to bottom programmatically. All you don't have is the designer interface :(
