Hello. Can you please help me? I just followed the steps but unfortunately it doesnt work on me it says that "An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll" please help me.
When I give a password field value as integer it doesn't show any error msg... Bt when I give a password field value as date format it shows a error msg at Dim count = convert.ToInt32(cmd.ExecuteScalar()) what should want to do??? Did I want to change a code for that particular line..... Can u help me??
"An unhandled exception of type 'System.InvalidOperationException' occurred in System.Data.dll " this shows at the connection state which has connection Closed and connection Open
Kindly, check your code again and make sure you wrote the if condition to check connection state, if not then write it... exp If connection.state = ConnectionState.closed then connection.open()

How to solve connection string property has not initialized error
Assign the connection string to the connection object .
At the moment this only gets the one user name and password from the database, do you know howi could add more usernames and passwords in and use more accounts?
Create sign up page to add more Accounts in Database.
