Access Privileges By Buttons Enabled/desabled?
Mar 11, 2011
making a program that will have access privileges (for example, some users can add some kind of information but not other, or visualize some pages but not others). I want to make this access control by relating each button in my project and making it enabled or not to the users. For example, if the user can add only information A, the button "Add New A" will be enabled, but not "Add New B". For doing this, as my project have many buttons, i thought about a sub form relating every single button of every form in my project

As i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.

I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?

I'm using a repeater ListOfArticles and have controls inside it like ddlSizes and btnSelectArticle. Normally you can just double click the control and in the aspx.vb page you can specify an action. I have heard something about Findcontrol, but can't figure out or find much information that I understand. I don't want to sound like an ass, but I would really prefer help for the aspx.vb page and not in C# or Javascript.
An example of what I'm trying to do is, once you've clicked btnSelectArticle the label lblSelection receives the following values Amount: txtAmount - Size: ddlSizes.SelectedValue.
<asp:Repeater ID="rptListOfArticles" runat="server" DataSourceID="objdsArticleList">
<asp:DropDownList ID="ddlSizes" runat="server" AutoPostBack="True"

Im am currently coding an application for auto updating ccleaner. Everything worked well until I enabled UAC.. I am using this project: [URL] to schedule the updating process, but when uac is enabled I get every time a message if I would let ccleaner installer make changes to my computer. The auto updating process must be done silently without bugging the user with prompts of uac.
When i manually check the "run with highest priviliges" box in task scheduler it does run without a prompt. But I can't seem to do this programmatically. Or I havent found it yet.

I wrote the code below to switch a user from DHCP to static networking (taking their DHCP assigned address and making it static). However on Vista and Windows 7 machines it does not work unless executed from within an escalated private command shell, even if the user executing it is a member of the local administrator group. I need to be able to email this script to users to execute on their computers (i.e. I have no remote access to them).

I would like to save let's say "HKLM/SOFTWARE" into file using API. First I open the key using RegOpenKeyEx. This works fine as I see that the ReturnPointer is different from zero and differs also when I switch from "SOFTWARE" to other subkey, therefore I assume no problem there.The problem comes when I want to save into the file. It creates only a blank file with return code of 1314. I have googled for this, but only found that this error means that application has no privilege to perform the action and I need to setup "SeRestorePrivilege" & "SeBackupPrivilege" property somehow. I haven't been able to find a good VB.NET example for this and as I am very weak with APIs I wasn't able to construct one of my own, therefore I would like to ask you for advice on this.Could you please help me on how to set the privileges so that I can export/import registry?

I am getting the above error when I attempt to run setup.exe as a non-administrator on Windows XP (sp3). This is for an application I created, and I would like to know what permissions the users need to install the application and updates. I am trying to understand the security issues when installing a vb.net desktop application, the .NET framework, and other resources such as the visual studio crystal reports engine. Any good resource which explains how this works for different operating systems and privilege levels?

I am running a client-server application and am having problems with privileges (I assume). The application is developed using 2005 Express. The Client is running Win XP Home whilst the server is running Win 2003. When the user on the client has Admin rights on the local machine, everything is OK; however when the user has only User rights, an error occurs: VB will not run.

I am trying to create a new folder in C:\Windows\System32\oobe but I cannot get sufficient privileges. Here is the bit of code that has the error
' I have "CreateDirectory("C:\Windows\System32\oobe\info\backgrounds") in the Form load sub
Sub CreateDirectory(ByVal Path As String)
Directory.CreateDirectory(Path)
End Sub
And then in Form Load I have:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
CreateDirectory("C:\Windows\System32\oobe\info\backgrounds")
End Sub
It keeps saying I don't have the privileges. Is there any way around this? I also need to put files in that folder later on.

A few months back I wrote a VB.net console application to migrate a group of about 100+ printers and the 1800+ users that use them from some old HP print appliances to a mixed Print Server and Direct to IP Printing solutions. The application uses a database to compare installed printers and remove old/invalid shares and remap to the new Win2K3 based print server OR create a TCPIP printer port and install the driver for direct to IP printing.
It worked really well, but users needed power user rights to create the TCPIP printer port. For the main campus this wasn't an issue, but the smaller remote sites need a solution that allows the app to be run by users without power user rights.
My solution was to take the "CreatePrinterIPPort" function and put it into it's own wrapper app and then call it as needed from the main app using a hard coded local admin account for the purpose, but I'm running into issues when spawning the createport app. If I run the app standalone it creates the port with no issue, but when I run it in my test app to spawn the createport using the CreateProcessWithLogon API the port creation fails with an "access denied" error. I'm limited to using .net 1.1 as 2.0 isn't in our environment throughly and I was told it wouldn't be pushed just for this app.
