Error DB Cannot Be Found.No Username Or Password On The DB
Jun 22, 2010
I can insert into my table by the bindingnavigator and dragging textboxes straight from the DataSet entering them and saving. But I want to insert into the DataBase via code and in order to do this I have used the below code to connect. I use this code to test the connection and cannot get it to connect. Just get the error to say the DB cannot be found.No username or password on the DB
Private Sub btnDB_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDB.Click
Dim connString As String = "Data Source=C:Visual Studio 2008ProjectsCollegeBetfairBetfairDB.sdf"
Dim myDB As New SqlConnection(connString)

I have a login in system that i'm creating for a game. I have this code for checking to see if the username and password are correct in the text file.[code]I want to know how to make the for loop stop once the username and password have been found correctly.Also, where would I put a message box saying that the username or password are not correct if they don't match up or they're not in there at all?
It has been giving me a huge headache since last night. Anytime I try to add new record into my database,this error message keeps coming up: "Error: INSERT INTO Customer(Cust_ID, Name, Address, Username, Password) VALUE. I don't know where the problem lies.
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.
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?

i am trying to do a for loop to give the user 3 trys to get the login username and password right. the username is User and the Password is VB. the code i got so far is a if function Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
i have a problem when adding username in my registration form..registering same username is allowed in my program..i dont want to allowed this. How can i make it using SQL..if the username exist dialog box will appear that the username exist
the below code is the login form. If type wrong username and password, MsgBog will pop up. So, my question is how to reset the password and username after the wrong username and password. I try to put Me.ResetText() but still can nt function because the old usename and password still remain at there.
I have been coding a Reset Login Details form, the user needs to enter the new Username, the new Password and the Current Password.Here is my code below - something in the form is not working as i am getting an error when i fill in the form about the INSERT INTO statement.
Imports System.Data.OleDb Public Class frmChangeLoginDetails Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
I'm currently working on a library system. i have a registration table. there are my fields in that table as well as username and password. then i have a login form. i want to use the same username and password as in the Registration table for the user to login.
in my login form there are 2 txtboxes namely txtUsername.text and txtPassword.text
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.
I have a form just like the login form in VB.Net. The usernames are prepopulated on a combobox with datas from the SQL DB backend, and the text box for the password entry is empty. My code is working but what I need help is, for the code to validate the username and password entered against that stored on the SQL DB backend. Like when the user selectes a wrong username but the password entered is correct, there shld be a messagebox like "The username selected is wrong", or if the username is correct and the password entered is wrong then the msg is "The password entered is not correct, please type you password using the right case".
Try conn.Open() Dim SelectStm As String = "SELECT * FROM tblStaff WHERE UserName = @UserName AND Password = @Password" Dim objCmd As SqlCommand = New SqlCommand(SelectStm, conn)
I have successfully saved account details to a .dat file (username, password, account type).the issue is however, that any username works with any password, for example, if the file were "user1 password1 user2 password2".I would be able to log in using "user1" as the username and "password2" as the password, i think i'm missing something?
I had one user in my db and when using this code it validates my username and password, but when I added a second user, it does not validate the second user, only the first one. I removed the first user and added it to my db after the new user, but it did the same. What can I do to make sure it actually runs through rows in the db and compare the information in the text box with the information in the database?
Dim sqlStatments As New SqlClient.SqlCommand( _ "SELECT * FROM Users", UCSMISDB)

I want to read some data from a website using a user and pass. Actually the website is accessible without user and pass but I want some data which is only accessible with my user & pass (consider yahoo.com which is accessible even if you're not signed in). I don't know whether vb can do this or not.
The lbl text should show "Incorrect Username/Password" if the Username and Password do not match.
Code:
Protected Sub btnLogin_Click(sender As Object, e As System.EventArgs) Handles btnLogin.Click Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:UsersBrianDocumentsVisual Studio 2010WebSitesPetLandiaApp_Datadb.mdb")
