I have a problem in adding/creating a new user to the system. The data entered didn't successfully inserted into database. It didn't show any errors too.
Protected Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim cmdInsert As OleDbCommand
Dim strInsert As String
[code]...
Username:
Password:
Login
Create Username
Exit
The login button
If TextBox1.Text = "Admin" And TextBox2.Text = "ABC123" Then
Police.Show()
Me.Hide()
[code].....
That it saves the Username and Pass so the next time I login, it can use this Username and Pass.
I'm trying to create a simple user tracking system so whoever has the program open can see who else has the program open. I know how to retrieve the username and everything. What I was doing was updating (loading and saving) a listbox with a text file on the network with the usernames in it. I can't get it to work right and I think its because the simultaneous opening and saving of the same text file by multiple users. I know this isn't technically the best way to go about doing this but it seemed like it should be the easiest. I don't want to make a huge project out of this because it isn't that important, it would just be nice.

I need some trick to make some good and safe "Login" to application system with username and password.
Can anyone help me to break down the instructions for this assignment.Create an application that allows the user to type in a 32 bit number using the binary system, and convert that number into the decimal numbering system.For example, the user types 000000000000 0010 (where there are 30 leading 0's, 1 then 0 from left to right), and the output would be 2.The user will type a string that is 32 characters in length.A For loop 'reads' each character using the x.substring(i,1) where i is the current character we are reading and 1 means one character only,and x is the entry the user typed (use a Textbox to get the entry but Inputbox is also ok).When you start at the first character (from the right) then that value is to be * 2 ^ 0 then the second character is to be * 2 ^ 1, then the third character is * 2 ^ 2, hence:( x.substring(i,1) converted to Integer ) * 2 ^ j represents the decimal value of the current number (0 or 1) we are reading.A variable is needed to accumulate all those values.After the loop is done, display the accumulated value.To test this code on a simple version, enter a 4 digit binary number, where 0010 is decimal 2, 0110 is decimal 6, 0111 is 7, and 1000 is 8.
My understanding is the user must enter 32 digits into a textbox. The textbox should place limitations that only allow the digits "0" and "1". This error could be displayed to the user with a messagebox that then asks to reset the value orginally inputted into the textbox. My understanding is I should continue creating the formula of the position of each character where the third character is *2^2, fourth is *2^3, fifth is *2^4 and so on? I don't understand the formula and how it works.
I try to create a form that managing the access level of user management system.The model I use is the following :I create a connection to database I create a DataAdapter to transfer the data from the database I create a Dataset to hold my data My form consists of the following :A ListBox that list all the access level namesThree text boxes: the first for the record ID The second for the access level name And the third for the discription of the access level Five check boxes:One for writing rights One for the deleting rights One for the Updating rights One for Printing rights And one for Special area access rightsSo what i do is the following :I create a connection string I create a new connection to my database server I create the DataAdapter I initializing the DataAdapter command such as SelectCommand, DeleteCommand, e.t.c.I fill my DataSet with the data DataAdapter get from DataBase I binding my controls to DataSet I setting the DataSource property of the ListBox to my DataSet I setting the DisplayMember to the ACCL_NAME column of the DataTable inside the DataSet I setting the ValueMember to ACCL_ID column of the DataTable inside the DataSetUntil this time all are fine ! ! !The question is :When i try to add a new row to dataset by using the following code i have a problem :
Dim newRow As DataRow = Dataset.Tables("TableName").NewRow newRow("COLUMN_NAME") = Binded Control Value DataSet.Tables("TableName").Rows.Add(newRow)
I need to create a notification system for my application that will alert the user once new items have been sent to their queue, which is made of up database entries. The latter part of this question may need to be asked in the database forum, but I guess we'll figure that out First, since I haven't created anything like this before, I need some direction on what the best possible solution would be.The notification system should always be running and work independently of the main app. With this requirement, I thought a Windows Service would be best.
The notification itself will just be a quick form that alerts the user. I'm sure most of that will be fairly easy to create. The only issue I'm wondering about is how to constantly check the database and determine a new record has been inserted.Would a windows service have a timer or something that allows me to constantly check?If it does, how would I determine a new record has been inserted?

I'm writing an application which has user authentication system, basically, when the user open the software, he has to enter his/hers username and password which are retrieved form a access data base, and if the user is set as admin then it enable some features, I couldn't figure out how to read the column lets say, IsAdmin table, which will store an value of 1 or 0 for example. I need a concept of how build a login system with levels or whatever you guys call it...
View 2 RepliesI have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.

I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.

View 2 RepliesI need to define some roles in my program with defined permissions. Let's say the administrator can have access only to certain features. The officer in charge to certain features and the user as well. for example, I have several group boxes and the user can access one of it only. So how i do manage these permissions? What I want do is have the roles already with the defined permissions. When I create the user and assign the role, the user should get the permission automatically.

Background: I need to create a user account and Modify it's registry before the user logs on the first time. Creating the account is done by using the Winnt provider (works great). To create the profile I'm trying to use Process.start to launch a process as the newly created user. With the use of loaduserprofile property the users profile gets created and i can do my regwrites without problem.

Using the .net 3.5 framework and C# I'm trying to add a new user to AD from C# and can't find any examples. I see that the PrincipalCollection object has an overloaded 'add' method but can't seem to figure out how it works. Can anyone help?
How create a new user object, add it into AD. Secondly, the user that will be adding in new people may not actually have the security to do this. Is there a way that I can impersonate another user account that will have permissions and add the account that way?

View 8 RepliesI created a Login system using the Login Form from VB 2010 and connectected to a DB table called "Useri" with 4 columns: "ID_U" , "UserName" , "Password" , "UserType". The login form works to authentificate user, and my application starts. My app has 5 buttons and i want them to be restricted by user type
If admin - full acces
if Operator - 1 button(that leads to a form with 4 textboxes that edit a row from a database)
if guest - 1 button that leads to a form with a datagrid
So, if a guest user clicked a resticted button a msgbox appears.
My login form code looks like this.

View 8 RepliesI have a pretty extensive application that has been built to provide SSO to several web applications via OID. The problem is that we have seen some users getting "orphaned" on a role for one of the applications. I have written a method that returns the distinguished name for all of the users with access to that role. To perform the cleanup, I am trying to make sure that the users returned in the previous step actually exist in OID. I have been using the System.DirectoryServices.Protocols.SearchRequest class when searching for users or roles, but it is not working for a distinguished name. Below is my method. It has been changed a couple of times to try different ways to make it work.
