I have written three Program modules in a program.
1. First makes connection to SQL SERVER 7.0 and Fox pro files. Then made some Remote views updatable.
2. Second Program transfers data from Fox Pro to SQL Server 7.0
3. Third Program transfers data from Fox Pro To SQL SERVER 7.0 from other directory.
If I run these three programs individually(manually) it works fine but when I run as a single program in Click event of the Button like :

do connectionhu.prg
Wait Window ' Connections are Established' NOWAIT
do importhcfa.prg
Wait Window ' UBs are transferred' NoWait
do importub.prg
Wait Window ' HCFAs are transferred' NoWait

It runs first two successfully but gives me following error after finishing second program. It gives me this error again if swap the last two programs

"The following system error has been encountered:
Error #1
Message File 'Parent' doesnot exist.
Line : 5
code do importub.prg
Method click
Object: A system error has occured, pls report this problem.

Thanks
