I believe the OP wanted both scripts to reside in the same file, rather than
in two files with the same base name and location.

If so, there are a couple of approaches:

- write a batch script that creates the vbscript file to be called. This
should be located in %temp% where the user will have the required
permissions, and where two concurrent users (if on a shared folder) will not
interfere with each other.

- write a vbscript that creates the batch script file to be called. This
should be located in %temp% where the user will have the required
permissions, and where two concurrent users (if on a shared folder) will not
interfere with each other.

It might be possible to avoid having to create the second script file to be
called altogether, but that would require two things:

- combining the two scripts syntactically in such a way as to cause each
scripting host (vbscript and batch) to ignore as comments or skip over the
script of the other language without throwing errors. I have seen examples
of this with other language combinations.

- getting one of the scripting hosts to accept script in a file with an
unexpected file type. This might be possible with WSH, however, I have not
tried it myself.


Yes, I am looking for a trick along these lines and would prefer not
to have to write out any files.

OK, then, all you need to do is to find a way to combine both languages into a .cmd file, run it as a batch script, and have the following batch command to re-launch the vbscript code in the script:

cscript.exe //nologo /e:vbscript "%~dpnx0"

We will be interested in seeing what you come up with...
