.NET Secure Login USING MD5 AND MYSQL?
Oct 3, 2009
I have login form, and it works. but only if passwords are not MD5. I would like to ask how to improve my code, so my application can use MD5 instead of normal text password stored in my MYSQL database.
This is the code I;m using now.
Dim mMySQLConnectionString As String = E3MCEncrypter.Decrypt(My.Settings.MySetting)
Dim MyADOConnection As New MySqlConnection
MyADOConnection.ConnectionString = mMySQLConnectionString
[Code]...

I'm having a problem submitting:
<input type="submit" value="Secure Login">
How can I submit by value"secure login". Is it possible?
I have tried something like this:
WebBrowser1.Document.Forms.GetElementsByName("input").Item("Secure Login").InvokeMember("click")
And all the variations with it and no luck.

I would like to create a secure login page for a pre-defined set of users (so no creating username/passwords by the users themselves). I've looked up a few sites and they all seem to suggest using Microsoft's Membership or something. I am not very sure as to why that's used, but all you need to know is that I will be creating the login details. I just need to make the login secure, ie, no duplicate logins, no logins from different browsers and cookies and sessions and encryption and all that. Any one have the code/links to where I can get all this?

I am trying to create a script that can login to a secure (HTTPS) website using credentials I supply then use MS' bitsadmin tool to download a report from the website. Once I automate this, I can then automate some processes of handling that report. So I am taking this step by step and trying to focus on getting the autologin portion to work before taking any other steps. The website I am logging into is not your typical site, it requires 3 fields 1) Organization 2) User Name 3) Password. See attached image as a reference. Also I have attached a text file with the source code of the relevant portion of the website login page.
So I hunted around and built a script off of a couple others I found and I am very close. See below for my script. The main problem I think I am running into is the stupid security alert popup I get from IE. I have no idea how to use the "sendkey" function on this popup to send "y". If I did, I think the script would work. When I run the script IE opens up and the security alert popup appears. I can wait as long as I want, but the popup doesn't go anywhere and IE just seems to sit there. [Code]

The GetMD5Hash's method is using for to decrypt the MD5 hash to turns into the actual strings and MD5Hash's method is using for encrypt the strings into md5... However, the connection strings can be sniff the packets sent out. How to decrypt the MD5 hash and how to blocked the connection strings in the packets sent out??

I'd like to be able to to login to a secure website directly from within my VB.Net 2005 app.
I can use the following to open the page in the user's default web browser
System.Diagnostics.Process.Start("http://www.xxx.com/login") When you visit this webpage you're prompted for a username and password (using the .htaccess/.htpasswd method).
I'd like to be able to bypass the login popup and go straight to the logged in form (I have username and password stored in my.settings

I have the lines above to login by database. However, I really don't know why always give me the error: "Incorrect fields". 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.
Try
Dim MySQLConnection As New MySqlConnection("server=localhost; user id=root; password=; database=DB")
Dim MySQLQuery As String = "SELECT * FROM TableLogin WHERE Username = @username AND Password = @password"
[CODE]...
I already tried to show the data of the database into a Datagridview and it works fine, it displays to me all the rows that I had add in the database.

Simple question (I think)Is it possible to create a login system interact with a MySQL database through a PHP script? the only tutorial I have found on the web is this, but its not a login and I dont understand it very well.[URL]..basicly I have created the login to directly connect to the MySQL, and since this project will be going live, my host does not allow me to connect remotely to the database, so I have only got a php script to do that with.
I already have a simple function on the php side, all I need the script to do is return a value to vb.net to tell it that its correct or its incorrect.And I need the vb.net application to get the value and login with the provided username and password and if its incorrect to show a message box and if its correct show a different form.

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.

i recently added a login that uses mysql database now it use to pull data from text file but as i said i made it use mysql now..it works great locally but when i sent it to a friend to test the login he got this error. unhandled exception has occurred in the your application. if you click continue, the application will ignore this error and attempt to conttinue. if the click quit, the application will close immediately could not load file and assembly 'MySql.Data. version=5.1.7.0 Culture=neutral, public key token=c5687fc88969c44d' or one of its dependencies. this system cannot find the file specified.not sure what to do i was thinking about having him install the MySQL Connector net but i thought i would come here first and ask..and can someone also help me on how can i retreive data from the login part? i can get it to keep the username but for some reason i can pull the rest of the data here is the login script.[code]
