Question about: My.User.IsInRole

Fri, 11 Apr 2008 15:50:01 Z

I hope this is the right place for this question - I haven't found
any other group whose name even vaguely would seem likely
as a place to ask this question.

I'm working on a (VS2008) VB program. It is likely that any
number of people might be able to access the program but I
wish to control what (specifically) they can do by using their
membership in either a local or domain group.

VS2008 makes available the "IsInRole" construct which when
called returns a T/F if the current authenticated machine user
is a member of one of a set of local, domain, or global groups.

It is used as follows:

     If My.User.IsInRole( _
          ApplicationServices.BuiltInRole.Administrator ) Then
       ' Whatever code is to be executed...
     End If

This works perfectly as long as the "role" is one of the VS2008
(and NT) standard groups - Administrator, BackUpOperator,
etc. Unfortunately, these doesn't seem to be any method/way
to specify a group which might be created for this purpose,
like "SiteCoordinator" or "SeniorMonitor."

Is anyone familiar with either how this construct can be used
to determine membership in a created group or of some other
method (preferably in VB) which can be called via a VB
program and determine whether an individual is a member of
a group - local, domain or global - or not?

Thanks.

Hi ,

You need to use role-based security mechanism in this scenario to authenticate the user. Commonly you can use the following code snippet to authenticate a user.

Dim principal As IPrincipal

principal = System.Threading.Thread.CurrentPrincipal

principal.IsInRole("your group name")

Well, I had a chance to try suggestion which was offered but, while it made good sense I haven't yet been able to get any code working. (I've read and tried most if not all of the on-line examples and they all are either insufficient (in details) or (apparently) flat out don't work. I haven't given up but I will keep working on it although I may move other elements of the project closer to the burner.

My thanks. Maybe there'll be a miraculious (ok spekk since that doesn't look spelled correctly) happening which will pour out perfectly working code.

(Boy I wish this thing had a spelling checker built into it!)

Raquel,

You were kind enough to reply to an earlier question (about role based security - which I still haven't really gotten working, but...) amd I am hoping that perhaps you can direct me on another item.

If you select the "File" option from the system menu and choose to create a new folder (File|New|Folder) you always get a (an empty) folder of the same size (displayed). Are you aware of any method of altering the size (registry or otherwise) of the folder?

In conjunction with that, there are COM items (I suppose) that plave an *.ini* file within the a folder which contains the name of an icon file (or dll and icon number) which is displayed as the folder's icon.

Might there be aware of some means which could store the folder's "height" and "width" in the same sort of file so that it would always be restored hack to the same sife? Being able to post the X and Y
location there as well would be a nice touch.

Thanks.

David
