I have an application that is writing a comma separated values file. How would I go about altering the permissions of that file from .NET - for example to give read-only permissions to a particular active directory group?

I'm trying to set ACL's on a folder using Directory.SetAccessControl. More specifically, I want to grant "Users" full control on a folder. AddFileSecurity works perfectly. AddFolderSecurity does not. It's result is that "Users" will get added to the folder's ACL but "Full Control" is not checked off (nor are any other permissions).

View 3 RepliesI have some code that queries all the printers on our print server and returns a list. I need this code to work so please don't reply with comments asking why I am using it when you can simply type \Server to list the printers (I know this, but need the code to work as part of a larger application). When running the following code on an IT PC with admin rights, it works. When running on a restricted user PC, it doesn't. How can I add permissions in code to elevate the EXE to 'run as administrator'? [Code]

This program is a small ADOX database with a single data entry Form. Originally written in VB 2005, it was copied into the VB 2008 Project folder. Opening the file in the IDE, it went through the Conversion process, nevertheless, because of the following error detailed below, the program will not accept any changes.
Error List: Warning 1 Unable to find manifest signing certificate in the certificate store. AppointmentsMissed (<the project's name) Under Security in the project's Properties Window these suggestions are made: Visual Studio was unable to determine the Code Access Security (CAS) permissions that are applicable to your project. The most likely cause is that your project references a strongly-named assembly that defines custom permissions, but that is not properly installed in the global assembly cache (GAC).
To correct this, try the following: 1. Ensure that any custom permissions defining assemblies referenced by your project have been properly installed to the GAC. If any of these assemblies have been rebuilt or have had their version numbers modified, you must install the new assemblies in the GAC. 2. Restart Visual Studio.

View 4 RepliesI've added an FTP client to a batch publishing program that I wrote about a year ago. The batch program "publishes" CAD files from "Pro/E" to "eDrawings". Upon publishing, some of "eDrawings" files are automatically uploaded to an external server via the newly written FTP client.The publisher and FTP client are working great.I'd like to add functionality that automatically changes the permissions on the files I'm uploading to our unix server (RHEL5). When I do this via SSH, I simply utilize a chmod command (i.e. chmod 0755 file.htm).I'm using VB.Net's DirectCast in my FTP Client.Is it possible to change the permissions on the files I'm uploading via FTP once they're on the server as part of the file uploading process?

Ever since I upgraded to Windows 7 Professional I've had constant build problems with VS 2008. I can't use the Hosting Process (not that I normally do) because at build I'll be notified VS could not copy a support file (the hosting exe). In addition, every time I build I'm told my previous exe is in use by another process and cannot be accessed. My only recourse is to manually delete the file. That works a few dozen times but eventually Windows stops letting me delete it and tells me that I require permission from an Administrator to make changes to the file (I'm the administrator,

View 1 RepliesI've got two programs, one is the main and the other is the updater. So far iv'e got it so that the main program checks for an update by comparing its version number with the latest one that's stored as a text file on the server. If there's a newer one, the update program is started and the main one closed. The update program will then use a web browser component to navigate to the download link and download the new version. The only problem I'm having at the moment is, How can I get the new downloaded version to replace the current one in Program Files? and will this cause permission problems?

View 1 RepliesI've been struggling with this problem in VB.net for a while: whenever I try to access the My Documents, My video's or simular in Windows 7, I get an access denied error.

To confirm, I also get a nice UAC popup when starting.The app accesses the files twice. Once to calculate the file size, and once to actually copy the files.
