W7 isn't letting me delete a dll due to access rights (see FAILS HERE). You see, I need to talk to 2 pieces of hardware (both with same dll name). For XP I have been copying the dll at startup (based on my hw type) without issues.
Public Sub SetCorrectHardwareDLL()
Dim dll As String = Application.StartupPath & "vxlapi.dll"
Dim vec As String = Application.StartupPath & "vxlapi.vector.dll"

What type of coding requires administrative rights? Does deleting files or copying files or using the shell / system.diagnostics.process.start()
View 1 RepliesI developed a windows application that uses a SQL Express database. I created a Setup project as well. When I install the application, the database is deployed with read only rights causing errors in the program. Of course, I manually change the rights to Full Control and the application works great. How do I get the database to deploy with Full Control?

The problem is that the acceess rights are not recognized correctly. If I log in manually with the same credentials then the rights are set correctly. Is there something else that need to be set for this towork correctly? I just realized I clicked VS.net instead of VB.net (moderator move this to correct area.)
Background: I have 2 Apps. One spawns the other as a 2nd process. Both need Adminstrator rights to run.The below code (which spawns the 2nd app from the 1st) works just fine from my released Application (when I right click the 1st app icon and start as Administrator).
Problem is, from within the VB Express environment it does not. The 2nd app starts, then complains about Access Rights.Can I start a process with Administrator rights in Windows 7 from within the environment?

I'm trying to make my application compatibile with Vista/7 UAC so I created a manifest file that gives me adminstrator rights which works great but the only problem that when my application tries to run with windows (via registry key I added) the application just won't run, and ideas how to run my application with admin rights when it loads up with windows?
View 7 RepliesI want a sure-shot method to test if the application was run via the UAC box and has full administrative rights. Earlier, I thought of making a folder in C:Windows for testing but running it on other computers proved to be a failure!
The UAC box provides all administrative rights to the computer to do anything(including making folders and creating files in places which needs there rights) and also makes sure that any child program so called or created also does have the same rights as the parent.Is there a sure-shot way to test if my application has been provided all the administrative rights that I can maximum get by the user while running the application or not? If yes, I would be glad to have to piece of code-work!
I am trying to read some data from the MBR using CreateFile, but I cannot get it to work without admin rights. The code I am using is like this:

Is it possible to read data from the MBR without admin rights?

View 8 RepliesI have a .net Windows Service developed in VB.net. I have a settings file in the root directory called Connections.XML and I am setting the basedirectory [code]...
When I schedule the service this is working absolutely fine in my Windows XP machine. But when I installed the same service in our development server (Windows 2003 64 bit Server) for some reason it is not able to locate this file.
I am having a windows application. That downloads files from server and write into the local directory. It works fine. When we try the same appliication in Windows 7. IT shows an error Access to the path denied (While writing to the local directory).
View 1 RepliesI've written a service in VB and a config app for the service which has a service start/stop button. In order to start and stop the service you need admin rights, under Windows 7 you right click on the exe and "run as administrator". This works ok, I've used the Visual Studio Installer to also create a desktop shortcut, but if you right click on the shortcut there is no way to run as administrator.
The question therefore is, how to run the shortcut as an admin user? Edit, if you hold shift down whilst right clicking you get the "Run as administrator" option, but you still can't change the advanced property to tick the box as its grayed out.

I have a VB.Net program which reads and writes to an Access database. I am trying to deploy the program using a setup (created with INNO Setup). Upon installation on a Windows 7 computer, Windows 7 is preventing it from writing data without changing the permission settings. It reads data but it doesn't write data. This problem doesn't happen in Windows XP. My question is: is there any way to make the Visual Basic .Net program write data to an Access database on Windows 7 from the setup without the user having to change permission settings?

I'm working on a simple data logging program, and I have little to no database experience. I wrote a little VB forms app to log the data to ms access and then graph the data, but I'm having trouble with adding records to the database. First, I created a simple one table database in access. Then, I added the database to the project as a data source, and gave it a data set using the wizard. Right now my code looks like this:

View 1 RepliesI'm trying to do a simple select query from a MS access database from my service. Has anyone managed to do this in the past using their Jet eninge?
I had originally debugged and tested the code in a windows form and it worked fine. Once I moved the code into a windows service and installed it, it bombs out and doesn't generate any errors.
Thing is, I just found a .mdb file on the net so not entirely sure of the database version. I'm running office 2007 and read that if you used the .accdb version on a machine that didn't have access 2007 installed (which is going to be 99% likely), you had to install some drivers etc. in order for it to work. That is not an option unfortunately which is why I went with the old .mdb that could use Microsoft.Jet.OLEDB.4.0 without any drivers to be installed.
Do I need to import something into this project to get this to work? I've attached the code below. I've added a comment after the problematic line.
Dim con As New OleDb.OleDbConnection
Dim dbProvider As String
Dim dbSource As String

I'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. The program that uses this code is a file-backup application, so it's important it can access everything. The app has admin rights, using this line:requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
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. Here is the file-size calculation code (that I found online:) Function GetFolderSize(ByVal DirPath As String, ByVal includeSubFolders As Boolean) As Long

View 1 RepliesI have programs written in VB2005 accessing mdb database in server. When the server run XP, it was never a problem (at the time, the folder was shared to all). There is a new rule in the company and we have Win 2003 server, and my mdb file must be stored in a folder in the server that the administrator (not I) have installed password. And clients are supposed to access it as user only. I can ask password as administrator, but the users of my program must not have the administrator password (which I can included in my program if necessary). How can I modify my program so that it can access the database? I assume I must modify my connection string, but I do not know how. I am currently using this:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source= C:Integrity ERPPBF.mdb;Jet OLEDB:Database Password=ABC"
