I have listBox control of user objects where each object has userName and Password.What I want to do is when a user enters userName and Password a method goes through the listBox checks for whether userName exists or not and if userName exists then matches the password.What I have in my mind is that to use for each loop but I think it would become complex so is there any better way?
View 2 RepliesOkay, I will be using Username &'Type' through out my project to verify certain things. On workbook open, I grab the username. Now I want to put the username list and type into a public array. The username list has a range name of UID and the type has a range name of UIDType. The combined list has a range name UIDCo. Which will be more 'resource' friendly? To load UID into one array and UIDType in another or to load the UIDCo into one all encompassing array? I will very rarely use either list alone, it will almost always be a combination of UID and Type verification.
2nd question is, I've only really used 1 dimensional array's before, any help on where I can research more about multi-dimensional arrays. I can pretty much figure out the what it does and how to use them. I'd be more interested in the actual syntax or coding samples.
I've see this application which can dig out our User Name from somewhere and asks our password. To be on the safe side, I typed my wrong password and it could cross-check that it was a wrong password and it asked me to type the right password. My question is:
How do you dig out logged in user's User Name?
How do you verify if a password given matches with the one really used to log into windows?
How do we auto-login by providing these verified details you say at a specific time by regularly checking the time using a timer?
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.

View 3 RepliesI 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

Does anyone know how to determine if the user password is empty?[code]
View 9 RepliesI'm working on a vb.net application connecting to mysql db which will have alot of users using it.
How should I deal with the user registration?I mean, I used to create a table with a username and password fields to store the users data in it, but in this case all the users will connect to the database with the same username and password of the server (in the connection string)
I need a pointer on how to do this thing right.What would happen if many connections established from many computers with the same user and password in the connection string?

I am writing a program that accepts a user name and password (the password must show up as *s). The user gets three tries to enter the correct information before the program is closed. So far I have the password showing up as the password in clear text the first time and in *s the next two times. The authentication also fails even when I use the correct user name and password which are password and user for now.

My problem is that I'm not sure where I should put the code. Should I use a module and set it as the opening form, or shall i put the code in the first form the viewer sees, which I tried and due to other situations the form has several different appearances, a this is causing a problem.

View 9 RepliesI am using VB.NET 2008.
On this Windows 7 Professional SP1 machine, when I run the following code in the program
FileCopy(sServer & "loglog.txt", Application.StartupPath & "log.txt")
I got the error "Logon failure: unknown user name or bad password."
sServer is 1 of our server machine.
The Windows 7 machine already logged in to the sServer as administrator, and it also login to the Windows 7 machine as administrator. I run the VB program as Administrator (right click - Run as Administrator).
In the Windows 7 machine I can go to Windows explorer and copy the file manually from the sServer machine to the Application.StartupPath folder.
When my application starts, one of the first thing it does is load a list box with data from an Excel file stored on our server.To prevent an issue I had with two or moreengineers trying to load the data from the same file at the same time, I added code that copied the Excel file to a temporary file (which is,hen, deleted when the data load is done).This has been working fine up until last week. Last week our company moved to a new building.The move included servers and all. Suddenly I'm getting inundatedwith complaints from engineers about my application.It seems that they started getting the following error
