Most definitely not. You'll earn an access violation error and the app
will be terminated. In Win32 the address space of each process is
~private~. The OS provides a number of alternate methods for
marshalling shared data cross-process including...
COM
WM_COPYDATA
DDE
Pipes Api functions
Api functions to create and manage a shared mem block manually.

If you create a variable of a UDT and if that UDT contains a standard variable length string then VB will leave the four "string pointer" bytes filled with zeros unless you assign something to the string, or unless you have previously done so and it is not a "fresh copy". ... Even if those bytes contain a valid pointer to a string they will cause a serious problem, because the pointer in the UDT data which VB passes to the SHFileOperation function is not in the place where SHFileOperation expects it to be, and is in fact offset by two bytes because of the "Integer padding" I mentioned. ...
