Make The Login Form More Secured?
Oct 6, 2009
I have taken this code from this forum and what I can see is that when the application is run and enter a username and password, it will compared with the username and password that is exactly the same as the database. What i want is that when the user enter the password, like it prompt out like "invalid password","the password must be not more that 8 characters". So how could I make it? Here is the code that I have used:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim con As New OleDbConnection("Provider=Microsoft.jet.oledb.4.0;data

this is my first time making an application so I would like to make a Login form in VB. I haven't gotten into any problems so far but my question to you are the following1) Is it possible for me to make an event/action that will allow it to work with the script that is php? IE: Application has a button that will scan all files in /public_html for viruses, when the button is clicked, it will send the event to cPanel and make it scan all files.2) Once the user has connected and all information has been verified make another window show and the new application will be the new window.Another question I have isRight now I'm using WHMCS(url..) for my billing system they have an intergtation code that I use for my web page and it goes like this
<form method="post" action="http://www.orionconn.com/clients/dologin.php?goto=clientarea"> Email Address: <input type="text" name="username" size="50"><br> Password: <input type="password" name="password" size="20"><br> <input type="submit" value="Login"> </form>

I've been trying to make a app that logs into a website. So far it didn't work for me.I have trouble because:
- The "pin" (username) box on the site doesn't have an ID. (Can't use getelementbyid)
- The picture doesn't have an ID either
Codes I've tried:
With WebBrowser1.Document
.All("pin").InnerText = "mypinhere"
End With
End Sub
This should have, in my opinion, filled in the textbox. Now I need to click the login button?Also I found this in the source of the site:
<img src="/media/img/text_AccountPin.gif" alt="Account Pin" width="93" height="10" border="0"> <input type="text" name="pin" class="form" size="15"> </p>
As we can see, it says
name="pin"
So I should be able to use "getelementbytagname" right?Also, the formId is logmein (log me in)
<form id="logmein"....
This is what I came up with:
Dim webbrowserDocForm As HtmlElementCollection = WebBrowser1.document.GetElementsByTagName("logmein")
For Each curElement As HtmlElement In webbrowserDocForm
Dim controlValue As String = curElement.GetAttribute("Value").ToString
[code]....
in the next code it's tagname is "input" or "text"? Because I found:
<input type="text" name="pin" class="form" size="15"> </p>
Code for filling in:
webbrowserDocForm = WebBrowser1.document.GetElementsByTagName("text")
For Each curElement As HtmlElement In webbrowserDocForm
Dim controlName As String = curElement.GetAttribute("name").ToString
[code]....
It doesn't give me any errors no more, but it doesn't work either.

I have a question in security programming. As all of us know, when we have a database with passwords or anything sensitive, we would like to encrypt it so it is not readable by other. Now I want to know, which of the method is secured or less secured. Is it Iterative Salting (1000x iterative) or Encryption method such as SHA 256, MD5, and all others. Kindly give me your opinion on this please.

I am trying to access a FTP secured site (SSL/TSL) and transfer a file in VB.Net using FTPRequest. When I try to complete the transfer I get an error back "The remote certificate is invalid according to the validation procedure". However when I connect to the same FTP site with FileZilla UI, I can transfer files with no problem. Why can do transfers with FileZilla and not in VB.Net? Does FileZilla have its own Certificate?

I'm trying to access a secured website using vb 2005 and webbrowser control. I've got the credentials, the script can pass the login page but when trying to navigate to the second page within, the page is being redirected back(to the first page after logging in). The second page I'm trying to get to retrieves the data from a database and displays some options for the user to select in order to prepare a report which can be downloaded after the fields selections. And I wanted my script to do this automatically without user interaction.
Public Class Form1
Private Sub TestButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TestButton.Click
Dim wb As WebBrowser = WebBrowser1

know open an xml file into a datagrid. The xml file is stored in a secured ftp with username and password. Just as an example if the site ftp.mysitesite.com, with username "xxx" and the password "XXX" has the file 123.xml, then how do I load 123 into a datagrid. Is it possible to store these info to a variable in app.Config and use that variable to access the site?

we do have incidents that two different users signing on the same website and seeing other's account, one possible reason is the session id assigned to each sign on user got a collision - although the possibility could be extremely low, but in our case it is not acceptable as long as it is possible. So I am looking for a 100% absolutely secured session id?
