View 2 RepliesI am trying to make a login system mysql try to connect to a mysql database.
Here is my code:
Imports MySql.Data.MySqlClient

MySqlConnection = New MySqlConnection()

I am trying to make a login screen that is connected to a mysql database. I cant seem to get it to work it keeps giving me an error that says ("there is already an open datareader associated with this connection which must be closed first")

Public Class SalePersonLogIn
Dim con As MySqlConnection = New MySqlConnection("Data Source=localhost;Database=testdatabase;User ID=fvfvxcv;Password=cxxvx;")
[Code] .....
After I send a post request to login to a site (using httpwebrequest), how do I check if the login is valid?
One way to do it is to read the whole html using
dim reader as new streamreader(response.getresponsestream) dim str as string = reader.readtoend and then check the html for any unique string (e.g. "log out"), to tell if the login is successful.
But reading the entire html is too long, so how do I shorten the process?
I tried
Dim str as string = response.getresponseheader("Set-Cookie")
But str is a blank string.

I am 120% sure that all the fields of the table are right, including the text that I put into my textboxs. I have already add a user into the database. I can make login in PHP but in VB.NET I just can't.

Dim MySQLQuery As String = "SELECT * FROM TableLogin WHERE Username = @username AND Password = @password"

im trying to let users login to an application i created in vb.net using the user table of the application's database in mysql i heard that The usual way to do this is to have just one MySQL user called "[my_app_name]" with the relevant permissions. Then my application uses it's own user table to control access to the application, and the one MySQL user to access the database.
View 2 RepliesI'm working on an application in VB.NET that has to connect to a MySQL database and FTP. How secure is it if I used it in an application that I gave to other people. E.g. if I was to let other people use this application would they be able to find out the MySQL and FTP connection details through intercepting packets or something like that? If that's the case how can I work round this? Also, part of my application is an uploader for users to upload files, is FTP secure for that or are there better alternatives ways in doing that? My server is a Windows Server 08 if that makes any difference.

I have written a new app in VB.net as a front end to a mySQL database held on a PC on the LAN running Windows XP. This worked fine for a while. The PC running the mySQL server started locking up (XP errors, not mySQL errors according to the event logs), so I decided to have a go installing Ubuntu to run the mySQL server to see if that was more stable.Ubuntu 11.10 is now installed, and mysql server is also running. I have imported the old sql database files and the mySQL workbench shows all tables are imported successfully.
HOWEVER, I cannot get my VB application to connect to the database now it resides on Ubuntu - just returns "Unable to connect to any of the specified MySQL hosts" when i try to open a connection. I am fairly new to Ubuntu and MySQL, and don't know if the fault lies with the O/S (a firewall config problem perhaps?) or if I need to do something different with mySQL.I can ping the Ubuntu pc from the client pc and vice versa.I have used ufw to open port 3306 on the server The ufw logs do not show any errors when I try to connect from the client pc, so I don't think it's a firewall problem (but could be wrong). I thought it may be something to do with the usernames I use in the connection string, but when I change these (deliberately use the wrong password for example) I get the same message, rather than a username/password error Is anyone else using a client PC running Windows (W7 or XP) to connect to a mySQL database running on a Ubuntu server?
I'm using the latest version of the MYSQL DotNet Connector (currently 6.3.7) and I am unable to connect to my database at all with it. It keeps giving me an error. I can connect the the database using SQLyog with the exact same information but not with this.
This is the error:
