How to get the value of the prompt environment variable
in [Visual Basic]
|
From: Leo on 14 Jul 2010 02:53 I need a way to get the value of the %prompt% environment variable. I would prefer it actually if I could get the value from a more reliable source as this is a console app I'm writing. -- ClassicVB Users Regroup! comp.lang.basic.visual.misc Free usenet access at http://www.eternal-september.org

Scrap the more reliable way section as it is one of the few environment variables that I don't mind changing. I forgot to mention I have tried Environ and GetEnvironmentVariable. I think it has to do with the fact the prompt environment variable is hidden according to http://ss64.com/nt/prompt.html. -- ClassicVB Users Regroup! comp.lang.basic.visual.misc Free usenet access at http://www.eternal-september.org

That, of course, has the problem of whether that gets executed in the current shell or a spawned one and whether they're the same or not.
