VS 2008 Log-in User Levels
Jan 10, 2010
i have a login form and it has 3 user levels - admin, manager & accountant - which have limited privileges using the system. For ex., if admin logged in, this user can access the whole system; if manager logged in, this user can only access the employee records; & accountant user can only access the payroll.
i actually have the idea but because i lack knowledge about vb.net, i don't know how to code it.
[code..]
At the main menu, buttons are enabled & disabled depending on the user level that was entered.

I need to create an application that allows staff members to login and see different things.I need to be able to have different user levels for this so that certain staff can see some things and other staff can't.I would like the login system powered by the MS SQL Database that the rest of the programs data is stored in.

I have my forms all set up, I want a button on my main form that says Volume. When clicked it either opens a window above the current form with a volume control. Or opens another form that has the volume control in the center. When the slider is moved up to 100% windows is at 100% volume, when moved down windows volume moves down also.

I'm trying to make a game in Visual Basic, but I can't figure out how to add in different levels.
Essentially, what I'm looking for is the Tab Control, minus the tabs. On a different note, is there a way to make a group of controls? Like instead of
TextBox1.Text = "Hello"
TextBox2.Text = "Hello"
I could have something along the lines of TextBoxGroup.Text = "Hello"

I'm looking for a recursive subroutine.I have the dataset from sql-server with in the datasource-table a parent- and a child-column.
I made a routine to put the parent-nodes in the tree.The problem starts with the childs over so many levels.I can write it out but it is to much code, I'm sure it can be done more efficient with a recursive subroutine.
.tv_Ana.Nodes(A).Nodes(B).Nodes(C).Nodes(D).Nodes(E).Nodes(F).Nodes(G).Nodes(H).Nodes.Add(Trim(sLev_nI + "-" + row_nI("MidCod").ToString()))
The tree will be about 25 levels deep.A few days ago I saw a recursive subroutine to fill the childnodes without the above difficulty to write alle the levels in code.That example I cannot find it any more, but it had a line of code more or less like this here below:
Dim
Nodes As TreeNodeCollection = tv.Nodes(A).Nodes
but it doesn't work yet!

I have a requirement to create a multi level treeview in ASP.Net (with VB) but I am completely stuck on how to start this. Currently my treeview is a fixed 2 level approach but now I need to rewrite this to be more dynamic and support extra levels being added into our database tables.So this treeview needs to support as many levels as needed without having to rewrite any code each time we want to add new level, Ideally we will just insert the data at the database level.I think I have the database part designed correctly, I created 2 tables Menu and MenuItemsMenu has 2 columns ItemID and ChildIDMenuItems has 2 columns ItemID and Description Doing this query:
SELECT
menu.Item_ID,
menu.Child_ID ,

Let's say I have three lists: Departments, Divisions, and Groups. A Department is made up of Divisions, which in turn is made up of Groups.The Divisions have the Department ID as a foreign key. The Groups have the Division ID as a foreign key.I'd like to produce a report that looks like this:

But since I can't include a subreport within a subreport, I'll need to go about it some other way. Is there a way to do this?

I want to use a DataGridView to show parent-records that are expandable to show children records. Basically, the top-level data shows class names, and expanding each class name shows the students enrolled in that class... that kind of thing.

With a steady tone feeding my audio input jack, the VU meters jump and bounce about 30%. I can also see the problem in the byte array of the capture buffer. I am running 8 bit mono so there isn't a chance that I'm getting a byte swap in a 16 bit word. My on board sound card is "Realtek HD Audio Input", direct sound 1.0.2902.0 and XP. Here is the real kick in the head, if I run anything that captures sound using the winmm library or if I use the winmm library in my application along with direct sound, the meters become stable. No errors are reported. Although I have written this in vb.net, I download another persons application that was written in C++ that uses direct sound with the same bouncing meters. I used the VU meters in Audacity to look at my audio levels and they are stable.

I am working on a multiple choice quiz, admin screen, student login screen where they choose their level of difficulty. I have been able to start the quiz, have the questions and answers filled, user answers question, check if correct or not, if correct then the score is incremented.I am able to set up a variable for 'level' and want to write some code so that whatever is selected then that table / questions will be selected and displayed to the user.
The way I'm thinking at the moment seems very long winded. I think I'll have to write an IF ELSE statement/case statement for each of the 'navigaterecords' and the sql statment for beginners, intermediate and advanced.Assume there is a variable 'LEVEL' - have not actually done this yet. Where the code refers to 'advanced' is where I have been trying it out to select questions from the advanced table.

I want to make different levels of access for a vb.net program i'm writing.I have a database called "stratocast". I want to show a specific form for entries in this table with "IsManager" checked and another specific form for those with "IsAdmin" checked.Im using MySql server and visual basic 2010 express
EDIT:To clear up any misconceptions about my post, ill explain further: In my vb.net application i have a login form with two textboxes; One for the username and one for password. I also have three other forms, one is called "frmAdmin", another called "frmManager" and another one called "frmEmployee".
On my database i have a table called "employee" with columns called "name", "title", "IsManager", "IsAdmin", "Username" and "Password".
IsManager and IsAdmin are both Boolean columns
This means that their values can only be 0 or 1 and the result is displayed as a checkbox.When the employee logs into this applcation i want it to check whether or not the employee is a manager, an administrator, or just a regular employee with no additional rights. If the employee is a manager, i want to show "frmManager". If the employee is an Administrator i want to show "frmAdmin". And if the employee has no additional rights then i want to show "frmEmployee".
I'd like to keep the configuration for access level checking confined to the one table but if it's better to have separate tables for each level of access (ie: tables called Admin,Manager, and Employee) then ill consider that too.

I have multiple TcpClient connections to my program. The connections exist as instances of a UserConnection class, that fires events on logon attempt and when receiving messages. My program also holds a Users object, which is a list of a User class objects, holding saved data (username, password etc) for each user that is allowed to log in.
It seems convenient to put a reference object of the respective user, in the UserConnection class (when successful login is verified). Hence, when an event is raised by the connection, the connection object will hold the user reference. As any event handler logic will need to know which user is responsible for the event.
If I don't make a user reference in the UserConnection class, then I need to loop through the users (less than 20) each time, to find the correct user. Not a big deal maybe, but i'm looking to understand how it would be done by an experienced programmer.
When data needs to be sent to a user, I need to access a UserConnection object. Hence the User class also holds a reference to the UserConnection class.

There's a table Category with a pk idCategory and a self-referencing foreign-key fiCategory.That means categories are "main-categories" when fiCategory is null. If fiCategory links to another category, it is a sub-category of it. But it's also valid that this sub-category also has 1-n sub-categories(with fiCategory linking to it's idCategory).Q: How can i get a list of main-categories,sub-categories,"sub-sub-categories", ...etc. with LINQ?I'm using typed DataSets to compare data from Server1/MySQL with data from Server2/MS SQL-Server.After normalizing and cleaning(there are several inconsistencies) i want to import the new data into SQL-Server. First of all i have to import the main-categories, then the sub-categories and so on. Otherwise SQL-Server would throw a constraint exception when i would try to insert a row with a foreign-key to a category that is yet not inserted.

I'd like to know how to do some basic calculations with functions.I'd have a texbox where a user would input a function eg:
x^3 + 2x^2 +2
I'd then want to display different values Eg, the X would be one, so the label shows something like
"X=1 => 5"
How would I do this?

If someone has any knowledge on how the following works, please advise as to why I can sucessfully Load a user token, Set token privileges to load the profile, impersonate the logged on user, create the environment block, obtain the roaming profile path, and load the profile perfectly fine as long as the application calling the functions is running as an admin. The application runs as a service on the local machine. As soon as I try to run the exact same code under the SYSTEM account, LoadUserProfile returns error 5. What must I have to change in order to allow the SYSTEM account on the local machine to perform the same tasks?

How would I be able, with the click of a button, allow the user to draw on the form? Maybe as if, taking a screen shot of the whole form, and then drawing on top of it? Dose not have to be a lot of colors, just a simple way to draw a line.
