Check/verify SQL Permissions For A User?
Mar 8, 2010
I am writing an Excel addin to read/insert/update/delete SQL data. I am looking for tips or code samples to check if the user running the addin has select/insert/update/delete permissions. this would work on SQL 2000, 2005 and 2008. I have found the following which works for SQL 2005 (and likely 2008, though I have not tested).
Use AdventureWorks
Go
SELECT * FROM fn_my_permissions('Sales.vIndividualCustomer', 'OBJECT');
Go

Dim l_managemantObject As ManagementBaseObject() = CType(securityDescriptor.Properties("DACL").Value, ManagementBaseObject())
For Each mObject As ManagementBaseObject In l_managemantObject
l_name = CType(mObject.GetPropertyValue("Trustee"), ManagementBaseObject).Properties("Name").Value.ToString
If CType(mObject.GetPropertyValue("Trustee"), ManagementBaseObject).Properties("Domain").Value IsNot Nothing Then

I have not been able to successfully verify a user with LDAP for an ASP.NET web application. I have done so on our own network against Active Directory, but this is against a server outside of our network that is OID (Oracle Internet Directory).Usually, I use the following code with no problem.
Dim myDirectoryEntry As New System.DirectoryServices.DirectoryEntry("LDAP://1.2.3.4:999/OU=SomeOU,DC=Something,DC=com")
myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Sealing
myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Secure
Try

After that, I haven't been able to find a method to verify a user's log in information with their password and then pull back some information.

I have a Session value that stores an integer representing what permission a user has to perform tasks in my application. For some reason now however, the function to check the permissions is not working. On the line indicated by the comment, the CTYPE action always returns the integer value, and not the list of Enum values. Can anyone please see what's going wrong here.

I have several text boxes which a user is supposed to input a numeric value and the program will use an array to verify whether the input in each text box falls within the numeric range allowed for that text box. So one text box will only accept number 3-7 and i'm supposed to create an array that will verify the input in that text box falls within that range. Personally, I would just do:
Dim intInput1 as Integer
intInput1 = CInt(txtInput1.Text)
If intInput1 >= 3 or <= 7 Then
messagebox.show("Input Verified")
Else
messagebox.show("Input must be a numeric value between 3 and 7")
End If
But this isn't what the assignment asks.

I'm trying to write vb code to verify a password input by a user to known table passwords in access database. The form has a drop down combo box that has userID's that are selectable. I'm trying to get the index number out of the combo box selection and use that to look up what the password should be. With that information i can then compare the stored password with the password typed into the text box below the combo box. All of the examples i've found that direct me show the code in regular Visual Basic. I'm using Visual Basic 2010 with the .net architecture.

I want to limit and verify the textboxes data which enter by the user i want to make a class in which i pass the textfield and the methods in that class return boolean value . First method check only numbers with decimal point. second method check only A to Z or a to z with some specify charecters. In java it is very easy by the parse INt methods or use class.

I have a simple .NET 3.5 app for changing some database fields using an ODBCDataSet. Now the Feature Creep is asking if I can hide or show tabs and other controls based on the user's database permissions. Ideally, I would like to control the permissions only on the SQL Server using Windows user groups, and the app would not have any built-in authentication or permission system--it simply uses the logged-in user's Windows account for the database connection. So thus it would have to "test" the permissions to determine whether or not to show the tabs for the user. For example, if they have "write" permissions to a certain table, then the tab for editing it would be visible; if not, the tab never loads for them. How can I list or test the user's permissions to the ODBCDataSet?

I've developed a Windows Form application that contains a function where a user will query AD using a users last name in an attempt to get a list of all domain users that contain all or part of the last name. This function works well if the user is an administrator, however in some cases a department manager, who only exist in the Domain User AD group, needs to use this function. When the user with only Domain User rights uses the function all queries come back empty. I can take the same application to another domain and user with just Domain User rights can use the function just fine.
I assume that the first domain that I mentioned might be using Group Policy to prevent Domain Users from making a query against AD.
Is it truly a Group Policy or some other setting within the domain that prevents this?
The current administrator of the first domain I spoke of is fairly new and has no idea of the workings of AD or Group Policy. All domains that I mentioned here I believe are running Windows 2003 Domains.

I am creating a multi-user application using VB 2005 Pro and SQL Server 2005.I would like to know what your ideas are when it comes to managing user permissions in regard to being able to view, add, edit and delete information in the database? Do you think I should have the end user type in the information into the VB application which then will create an SQL server user and then apply permissions to that security user or should I fine-grain the application by allowing groups to be created and then assigning permissions and users to those groups?

I have some code that queries all the printers on our print server and returns a list. I need this code to work so please don't reply with comments asking why I am using it when you can simply type \Server to list the printers (I know this, but need the code to work as part of a larger application). When running the following code on an IT PC with admin rights, it works. When running on a restricted user PC, it doesn't. How can I add permissions in code to elevate the EXE to 'run as administrator'? [Code]

I'm writing and application that creates a home folder for a given user. I can set the permissions fine, but on some of the folders I need to remove a specific group/user, "Everyone" would be an example for one of the folders. I can make it so that they are denied from all the permissions on the folder, but I can't actually get the group/user remove.

I'm creating an application that works with another I have no control over. My application needs to be able to create a user and change share permissions. Currently I am able to make a share, but I can't figure out how to set access permissions for that share.
The idea is that the newly created user (w/ password) will have permissions on the share I create.

I am using Microsoft visual basic 2010 for a asp.net site using c#.I am using the asp.net configuration for user registration. I have a comments form which I want to appear only if a user is logged in.I now there is a toolbox helper thing called Login View which does exactly what I want but as soon as I put a form inside the code won't compile because it cannot find the textbox fields.
I have the following in NewsArticle.aspx:
<asp:LoginView ID="LoginView1" runat="server">
<AnonymousTemplate>
<div class="postcomment">

If I take the form out of asp:LoginView it works fine. Inside I get the following:

Error 3 The name 'txtComment' does not exist in the current context NewsArticle.aspx.cs 59 68 Figmentville
