Converting Win32 API to VB.NET for Folder Security

[i23bam]

For the record, I am a newbie to API. Anyway, I am trying to use the Win32 API in VB.NET to set NT Security (Administrator ACE) on a remote server folder from within a backup executable I have created. The problem is I am trying to implement my translated version of the NTFS Permission example, at http://www.mentalis.org/apilist/LookupAccountName.shtml, to VB.NET and the code fails at one particular point. (BTW, I have chosen NTFS Permission example because it seems pretty straight forward for a newbie.) I have converted all Longs to Ints and added ByRefs where needed, but the app seems to quit at the AddAce Call (ERROR_INVALID_PARAMETER). Has anyone already converted this code or would anyone have suggestions for a fix?

Did you try the Win32 security library from GotDotNet
http://www.gotdotnet.com/Community/...mpleGuid=e6098575-dda0-48b8-9abf-e0705af065d9
or the stuff Data Marvel has? There isn't much reason to reinvent these
pinvoke declarations.

Joe, Yes. I did come across the wrapper class a couple of weeks ago, although the idea was abandoned because I was unsure how to integrate the c# project with my vb.net solution within Visual Studio.NET 2003. Would I have to compile the c# class into a dll and include the dll in my project to use it as an Imports Win32API? Also, if so would I have to migrate the new c# dlls with my final executable in order for it to run on multiple machines? Thank you for all repies in advance.

Yeah, just include the project in your solution. Then you'll have an exe
(or whatever you were originally building) and another assembly in a DLL
that you need to include with your project.

There is no worry about combining VB and C# projects in the same solution.
I do this all the time when I need to.

Hello,

You may take a look at following article to see if it will help:

Luke. Yes. I have taken this option into consideration, however the executable I am using must be portable, thus it must have .dlls inherent in all Windows 98, 2k and XP PCs to allow for its portability. It is for this reason that I chose the Windows API as the solution. I would hate to have to install the ASDI .dll on all machines wanting to backup. I know, however, the users will have to download the .NET package, but the Windows Update procedures make this task fairly simple. I also know that Visual Studio 2005 will have the Security Objects built in, but if I do not have to wait I would like to program for it now.

Didn't read the rest of the thread, but did you check out the Win32 security
..NET wrapper at gotdotnet or Data Marvel's library?

Are there any other suggestions for a solution?
