Create Folders and Write To Hard Disk Other than C:
in [Visual Basic]
|
From: Bee on 5 Mar 2010 20:36 My app can generate many gigabytes of data files (several megabytes each) per the user choice. For those who wonder, this happens over many hours and or days. I am making XP and up a requirement for using the app. So, for XP and up how do I do the following: (1)Set permissions on a different hard drive (other than C:) to read, write and delete data files. (a)for this user (b)for all users (common data). (2)Create a folder (assumes this is different than "normal"). I may be totally wrong, but I assume that reading, writing and deleting the file in this folder once created is as usual. (3) when I reopen the app, do I need to do anything if I find the folder previously created? e.g. set permissions again? etc.
From: mayayana on 5 Mar 2010 23:23 There's a compact class here that I use for my installers: http://www.jsware.net/jsware/vbcode.php5#perms There are 3 function: 1) Check the partition formatting. (XP is not necessarily on NTFS. It may be on FAT32. And a data partition can be FAT32. Permissions only apply to NTFS.) 2) Get current permissions on a file/folder/Registry key. 3) Set permissions on a file/folder/Registry key. The setting permissions function is basic: add or remove full permission for all. > My app can generate many gigabytes of data files (several megabytes each) per > the user choice.

There is NO reason whatsoever that your app should have to mess around with setting permissions. This is just going to lead to trouble down the road. If it's a "user's choice" then let the user specify where these data files should be created. And to that end, the user should only be specifying a location which he/she already has permissions. -- Mike
From: Bee on 6 Mar 2010 23:35 spankings do not work with me and it did little to help with the question. so how is the home user supposed to know how to set permissions? most of them can barely start an application. people have a right to use their PC as they choose so I am providing a option for them. read OPTION ! so they do not have to deal with the UAC at every mouse click. P.S. logical suggestions work with me.

Maybe I read it wrong, but it sounds to me like he's thinking of providing storage on a non-C drive because the saved files are so bulky. And that storage will sometimes be per-user and sometimes be accessible to all. If D:\MusicStore\ needs to be accessible to all, on an NTFS system, I suspect that *does* need permissions set. Your adamant position of "NO reason whatsoever" needs a qualifier: "....if this is software designed for use by corporate employees on company workstations." My impression is that his software is mainly for home use. Or do you really believe that in no case, on no PC, should people ever be allowed to share files from a common folder? |
