It's not the Visual Studio code as I have stepped through and look ok.
Shell("C:\Program Files (x86)\Microsoft Office\Office14\MSACCESS.EXE c:\BP Planning by PT_dept\BP Planning by PT_dept_fe.accdb", vbNormalFocus)
It is clearly try to launch the Access DB but failing.
I think there must be an internal path in the FE that tells where the BE lives.
This is now annoying, when it is so close.
Thanks in advance.
