Archive: Verifying a directory without using a 'directory' Page


Verifying a directory without using a 'directory' Page
I have a situation that I'm trying to resolve. I have come up with my own 'custom' page instead of using the standard 'directory' page. This is all fine and good. The problem comes when I try to validate the directory path that I get from the custom page. I cannot use DirVerify (because it is not a 'directory' page... (is this getting redundant?)).

So, as I see it, I'm left with one of two options: 1) manually verify if the directory is valid (check for available storage space, read-only dir, etc.) 2) find some way of flagging my custom page as a directory page.

If anyone has any ideas on either 1 or 2, or is far more clever than me and has option 3 that would work. I'd be most appreciative.

Thanks,
Kris


Technically, option 1 is the only option you can use.

Use the leave function of your custom page to verify the path and whatnot.


That has been my observation as well. It's just frustrating to know that there is a bunch of already existing and fully tested directory validation code that I'm not able to use. I'm still searching for a solution.

Thanks for your input Jason.

dang.

me too.


IMHO it is advised to put a feature request in the sourceforge NSIS developent pages. I have to admit, extending the use of dir validation looks like a valid and handy feature to me.


validate_filename is already exposed to plug-ins. Which other function do you think you'd need?


he mentioned the free-space validation...


That's simple enough to do without the internal check. The internal check is just comparing two numbers and is not located in any function to avoid the overhead.

I forgot to mention that you could also trigger validate_filename with $EXEDIR.

Push "C:\Program *Files   "
Exch $EXEDIR
Exch $EXEDIR
Pop $0
