System variables in path controls.

[Bryan]

.. or should I say the ability to use them in path controls.

I.e. for windows NT machines entering "%SystemRoot%" in a path variable would return "C:\WINNT" at runtime.

Hmmm.....

Methinks that the near term way to get this is to create a VI that parses an input text path, makes some system calls and/or calls to the registery to get that requested variable, then inserts and converts to path.

Since the syntax of environment variables varies between systems it might be best to directly call into platform specific APIs. On Windows this would be ExpandEnvironmentStringsA in kernel32.dll.
