i have a login form in a banking project.i set a userid and password for this login form and i did the code accordingly,it works good.In my form there are two fields namely:Userid and Password and a button named Login.
But i cant get any idea about what to do when the user wants to create their own userid and password?
I think i need to add a few more buttons to enable the user to create their own userid and password but i cant get the idea......i need some help.
Again,if i allow the user to create their own userid and password then anyone can use my project by creating a new account.........
Hence i am totally confused how to go with this.I need some urgent discussion so that i can get through this problem.

I am looking to create a simple password box that will ask the user for a username and pass, if the user is validated against the usernames and passwords in an .ini file the login box will close and launch a program also stated in the .ini file. I would also like to be able to launch different programs for different users.

I'm trying to create a password change form for my company's vendors. There are a couple of scenarios I could encounter doing this:
1 - User enters invalid current password
2 - New passwords do not match
3 - User's account is locked
4 - User cannot authenticate because password is expired
It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.

I have a VB.NET form that contains textboxes for the user to enter his details. I have a delete button in the same form that I want only the administrator or any authorized person to be able to use. Basically, I want to make the delete button password protected so that the normal user can't delete any of his details. only the admin who has the admin password can delete it. Is it possible to create a password protected button?

I have a oracle database. I use the OracleDataAdapter(Oracle.DataAccess.dll) for select, update, insert, delete operations. I don't set any (table) locks on my own(I only start a transaction). I have a oracle table named "test" with the entry "test1".
Now my question: Can Person A read the entry "test1" while Person B is updating/deleting the entry at the exact same time? What happens in the worst case? An old match/empty match or can it cause any kind of exception/error(e.g. "TableLocked-Exception")?

I am designing a fairly small application to manage a waiting area for a clinical department. There will be a receptionist who books appointments and updates exisiting appointments to say that a patient has "Arrived". In seperate rooms will be nurses who call patients who have "Arrived" and update the appointment as "In Session" and finally as "Discharged". The appointments are viewed in a flexgrid with nurses across the top and time down the left, patient names are displayed at the relevant times and the cells are shaded a colour to represent the current appointment status ("Booked", "Arrived", "In Session" and "Discharged").
I am using SQL Server as the back-end and Visual Basic 6 (I know) as my front-end.I have been told that there will be 2 or 3 nurses plus the receptionist logged in to the system but I would like to cater for growth.My question is what is the best mechanism to use in order to reflect the status change made by one user on the screens of the other users currently logged in?
I have been thinking about using a timer to refresh the data at a set interval but I do not want to keep hitting the server excessively (although what is considered excessive? we would be talking about a call for data every 60 secs per user). Plus the server could be serving data for many other applications so this is another consideration.Alternatively I have been thinking about sending some kind of message via Winsock to the other users notifying them of data changes as they happen. I don't have a lot of experience with this and am concerned about clients not receiving messages and users seeing old data. It also seems strange to me that once the days appointments have been retrieved from the database that "in theory" a client could go the whole day without having to query the database again to pick up changes - kind of scary.Some information on the data:We would probably be looking at around 100 appointments per day We capture patient name, date of birth, date and time of appointment and appointment status.What is the standard approach / best practice for this kind of scenario?

I have a button named button1 on form 1 I want it so when I click this button1 it will automatically make another form say form2 with say I dunno a textbox1 on this form2. The reason for this is because I want to make an application which will allow a user to create a form with certain things on it (what ever they choose).

Is it possible for a user to create a new button on the form, and for them to add their own custom code to it (lets say it's a custom toolbar with items)? I'm asking this because I'd like to have some way of creating add-inns for my webbrowser. I wouldn't be surprised if it's impossible in VB, but Firefox can do it, so I guess it's worth a try...

Am trying to create a multipage (or multitab) user form and each one of page (tab) has several textboxes in it. After user enters the input in the textboxes, the data goes into an xml file. All I wannna know is, what is the syntax for getting inputs from a textbox on some tab say Tab1. I tried this,
"
Dim Var as Double
Var = TabControl1.Textbox1.text
"
It doesnt work. "TabControl1" is the name of tabcontrol i have inserted and "textbox1" is the name of textbox, the value from which I am trying to read.

how to create a form that allows a user to load an input file? I'm assuming a form like a windows explorer window will be too difficult, or not? If it is then I guess I could just put a textbox on the form and ask the user to input the directory with file name.

I currently have a program that allows users to download files into a folder of there choice. I currently have 10 different forms all with a text box to show folder location and a browse button for user to find it, but what I want to do is create a form that will appear at the start where the end user can enter the folder location so that they don't have to enter the folder path for every download they want to do. How would I go about doing this I have a textbox, browse button and an OK button but have no idea what to do next.

I am currently creating a tool that can manage local user accounts on Windows-PCs. I am using the functions described on
this MSDN page ; and after some struggling, I got most of them to work.
Unluckily, I haven't found a way to set the option "User must change password at next logon" while creating a new user account. I use the
NetUserAdd -Function to create the new user. I set the level to 1 and supply a
USER_INFO_1 -Structure . This structure accepts flags, and the flag UF_PASSWORD_EXPIRED seems to be exactly what I want - but when I set it, the user can log on without changing the password first...
I'm developing on Windows 7 Ultimate 64-Bit using Visual Studio 2010 Express.
Here's my code:
#Region "Constants"
Public Const UF_PASSWORD_EXPIRED As Integer = &H800000
Public Const USER_PRIV_USER As Integer = 1

I've got a VB.Net form application that dynamically loads user controls based on which navigation link the user clicks on. I'd like to make it easier to use at Design time by putting a link of some sort to open the User Control at design time. The link would go onto the form in the space where the User Control will be going. This just saves a little time from having to browse through the files to open the correct file.
