I'm developing an installer, and I would like to write to a folder accessible only to administrators. So, I need to display the UAC dialog and authenticate as an administrator. I know I could do this by having a separate executable that I run from the installer GUI, but I'd rather a solution that allows me to authenticate whenever I want in the application. Is this possible in .NET?

I am writing a very specific program that checks and changes some registry keys in the HKEY_CURRENT_USERControl PanelDesktop key. I've had no issues with this in vista or xp. but windows 7 gives me permission errors. the problem is that Administrators group is missing from the permissions table in the registry for this key. I can fix this by opening regedit and right clicking permissions for this key and adding Administrators to the table. However I don't want the end user to have to do this.so how can I add administrators group to the permissions table of this key using vb.net code?Everywhere I look online people say don't write to this part of the registry if I don't have to. well I have to as it is a windows key that I must change. all permissions are set correctly for the program I just need to know how to add administrators to the permissions list in the registry in windows 7 using vb.net?
View 4 Repliesto add a windows user.The problem is i need to add the user to a group, but the groupnames are localized.E.g. the MS-example uses an english computer, which means you can get the guest group like this:
grp = AD.Children.Find("Guests", "group")
But on a non-english computer, the 'Guest' groupname is localized, meaning for example on my german language OS, the group name for Guests is "Gäste".Which means for the support example to run on my computer i need to change that line to
grp = AD.Children.Find("Gäste", "group")then it works.Now if the OS is any other language, how can I find the name for the guest user ?Or how can i get the guest user name from a sid ?
Dim Principal As New System.Security.Principal.WindowsPrinipal(New ystem.Security.Principal.WindowsIdentity(My.User.Name))I'm using My.User.Name in the example. I'm aware the My.User namespace has a IsInRole method, however, I well need to check a list of users and not just the current user so can't just use that or WindowsIdentity.GetCurrent. This exception is being thrown when declaring the Principal variable:"There are currently no logon servers available to service the logon request"

View 3 RepliesI am using System.DirectoryServices.AccountManagement to try to add a local account to the local administrators group with the following code but am getting the error below on the group.Members.Add(usr) line. Both usr and group are created as objects and if I create a Test group, I can add the user to the Test group. I know the group object is the local administrators group and not the domain group because i changed the description on the local administratrors group and the group object is correct so it appears to be something specific to the local administrators group.

I am trying to write a VB Script that will cycle through a folder in Outlook and take the body of the emails and format them to send to a MS Access database.
View 3 RepliesI've looked for code on this, and it seems needlessly confusing to me. I've tried some code I found and it doesn't return the proper value (I can't find the link to it now). So, I'm attempting to avoid that which I do not understand by writing a function that creates then deletes a file:
Friend Function GetFolderAccess(ByVal sDirectory As String) As Boolean
Try
Dim fs As New FileStream(sDirectory & " estfile.test", FileMode.OpenOrCreate, FileAccess.ReadWrite)
Dim s As New StreamWriter(fs)
[code]....
Through testing, this appears to work for both read and write access. I originally had a File.Exists before the File.Delete, but the function would sometimes return True when it should have returned False.

All i am trying to do is read and write files to a shared folder on a network in visual basic (VS 2010). I can go to the folder through windows without a problem and without being prompted for a password. However when i try to do it through visual basic, it cant find the directory. Here is my small snippet of code that i (hope) is telling me that the program cannot connect to the folder. [code] Are there any known issues with VS 2010 that may cause this? Maybe something else in my code that could have an effect? This is in my form_load event though, so it is literally one of the first things that runs.

Im trying to write a loop that will read through a number of *.csv files in a folder and then stuff the data into SQL. The code works and will happily put the data i want for a named file into SQL no problems. So when i had that working i then tried to loop it so that it would do the same for all files in the folder until all files had been done, and not error out if there where no files etc.
Maybe im tired (well, i am) or not had enough coffee but i just cant get this to work, it should be simple - i know it is infact, but its making ME feel simple.i think i should have an integer count in there, but similar examples ive seen dont use one. Also when trying to open the path i get an error at runtime "the path is not of a legal form"

I have a video encoder app made with VB6 that users frequently have issues with. The problem that people encounter is that files do not show up in the output folder where my application is set to write them. The output folder is located in C:Program FilesMyAppOutput. Vista users can sometimes click "Compatibility Files" and see the outputted files. Sometimes I must tell users to "Run As Administrator.."

View 7 RepliesI have a link on a VB.net aspx page that needs to open a folder in a subdirectory of a web site and provide read and write permissions so that files can be copied into and read from as well as deleted. ONLY from this folder.I have this funtionality working on a dev and demo PC but they are both on my domain. Clicking the link opens Windows Explorer and I can copy /cut & Paste, etc.The public/production PC is on the LAN, but not part of the domain. I know there are ways to allow folder read/write permissions on a public server like this but I am not too sure on the safest way to do this. The upside, the only users that need to have read/write/delete access are employees. Forms Authentication, ASP Membership directs non-employees to other pages within the site. Likewise, the membership directs employees to an admin section of the site.

View 20 RepliesI have a class library written in .Net that I would like to make available to VB6/VBA. What I tried did not work (obviously as I am asking this question). Here is what I did:
I Created a Class Library Project in Visual Studio 2010 Express and put the code in a Class Module.I opened the project properties and went to "Assembly Information" and checked "Make COM Visible". I went to "Advanced Compile" options and targeted .Net 2.0 (it's very simple code).I then removed all references expect for "System".I built the project (no warnings or errors) and copied the DLL out of the Bin folder into C:WindowsSystem32 I ran RegSvr32 to register the DLL and got the error: The module "MyDll.dll" was loaded but the entry-point DLLRegisterServer was not found. Make sure that "MyDll.dll is a valid DLL or OCX file and then try again.
Is it possible to have method have methods that are only callable externally and never callable internally?
Public Class Foo
Public Sub New()
Bar ' Should fail to compile as Bar is only accessible externally.'
End Class
Public External Sub Bar()
End Sub

I have a .exe program which has an embedded webservice running on port 800.I can access it locally via 127.0.0.1:800 just fine once the program is executed.I need to be able to send the service commands such as: * 127.0.0.1:800/dev * will get a list of devices attached to the program.
To my knowledge i need to forward port 800 on my router and then access my internet IP externally and I should be able to view/access this web service? am i correct?I am then wanting to create a PHP site which will send the desired commands back to the web-service running on my home pc.
