Wait for shell command to complete

Does anyone know of VBA code that waits for the WinSCP shell command to finish executing before proceeding to run vba code after the shell?

Would this help?

The solution suggested seems to be for MS Excel VBA.
I am looking for a solution for MS Access VBA.
Below is the shell call that I use.
I cannot see where the shellandwait function integrates with this.

Do you have any reason to believe that the code won't work in Access? I'm quite sure it will work.
