Trying to do this within Excel VBA but having a problem with the following
shell command. The command line switch can't open the named file.

Dim retVal
retVal = Shell("C:\Program Files\Microsoft Office\Office\MSACCESS.EXE
S:\My
Folder\MyFile.mdb", 1)

The problem stems, I assume, from the space in the pathname (something
over
which I have no control)

Give this a try...

retVal = Shell("""C:\Program Files\Microsoft Office\Office\MSACCESS.EXE""
""S:\My Folder\MyFile.mdb""", 1)
