'UnauthorizedAccessException' - Create The Username And Password In The Same .txt File
Jul 3, 2009
I knew that what I have doesn't create the username and password in the same .txt file. when i create a new user they both get thier own file with no text in them. When I tried to get the streamreader to access the previously created accounts, the only password acceptable is 'password'. I think it only accepts 'password' because 'Password.Read()' and it only created a .txt file Password when I typed it in. (I can't be for sure though). The top code is my Create User and the bottom code is my OK(accept created user).
Private
Sub CreateUser_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CreateUser.Click
If Not My.Computer.FileSystem.DirectoryExists("C:Documents and SettingsAll UsersStart MenuProgramsLogin Text To Speech") Then

I tried the following:
Public Function User_Login(ByVal unam As String, ByVal pwd As String) As Boolean

Now i called this function on the button click of my login form and passed the values of username and password textboxes as parameters to it. But the problem arising is that it is logging in by simply clicking the button irrespective of what is entered in the username and password textboxes.
I think this is because ds.Tables.Count is never 0(whether the username and password match or not) Use code tags when posting your code. Code tags are used like so =>

I am creating a winforms document manager. I would like to allow the user to upload to and open documents from a protected network drive. A specific username and password will be setup for the application so that only the application can access the files.
Normally when I allow the user to open a file I use the OpenFileDialog command. How do I add the username and password?

I have a winforms application and would like to allow the application to open and save files from/to a folder on the network (acting as a document manager). Only one user has access to the folder and I can hard code that users credentials into the application. Where using AD on windows server.How do I allow the application to do this?I would prefer not to use impersonation but from my research it appear I may have to. I would welcome suggestions for alternative methods. I do have some code for impersonation which seems to work. However I cannot open the file using process.start I get access denied.

1) I have a chat Program.
2) To access the Chat Program one has to put in ones Username and password in a Login Form.
3) TextBox1 = Username TextBox2 = Password
4) One clicks the "Log In" button.
5) HERE is the problem. I do not know how to check if the specific username and the password are correct. I have a file called "Users.dat". In there every valid Username(marked with a *) and it's Password(marked with a #) is contained e.g.*Username#Password.
I want my "Log In" program to check if the Username matches one of the usernames and if the username is found in the file, if the password provided is the same as the one standing behind the Username in the file.
6) If both the Username and Password are valid, the Chat Programs shows up.

basically i want to create a login to my program which uses the same username and password as windows login.I already know how to retrieve username and auto place it in the username box using
TextBox1.Text = Environment.UserName.ToString
i wondered is there an easy way to only allow access if the password matches up to their logon? i dont know about setting up databases but i dont think this option would work because each member of staff can personally choose their password.

While a web page -which needs login- is opened in my browser, if I close browser and re-open, I have to write username password again. But, sometimes when I close browser and re-open for the same page, it isn't needed username and password again? Is it about Session, Cookie? If yes, why are there different conditions?

when you log in a username and a password a msgbox will show that you are log in, and then when you enter the same username and password, the program will identify that the username and password is log out. no button will be use in here.
