Also, the more tests you are performing, the slower your app might become. For more information regarding Regular Expressions, you are welcome to look at these two MSDN articles: Because it is always easy to learn by doing things practically, you will be creating an app that makes use of Regular Expressions to determine valid input. NET application and design the form to resemble Figure 1. Obviously this only works for the formatting of the email. This means that as a programmer, you have the power to supply the exact pattern for the input you desire in any text input field. Again, certain special characters are obviously not allowed. They make use of a pattern matching system to match the input with a certain pattern of data.Figure 1 - These objects will determine if all our data is valid or not. Clear() 'Clear Text Box Name Valid = False 'Boolean = False Else Name Valid = True 'Everything Fine End If End Sub Easy one to start with. Focus() 'Set Focus To Text Box End If End Sub Private Sub txt Email_Lost Focus(sender As Object, e As System. Lost Focus Validate Email() 'Check Email Validity End Sub The expression may look horrible to the layman's eye, but look closer. To check if the user has entered an email that actually exists, you will have to find a different way such as to send a of some sorts.Maybe i am reading this post wrong but it looks like you are hard coding the user name and password into the code??? The function validates a username and password for a domain, and you can pass in all 3 params. What if my password changes or i want to give more than one person access to use my application? I added a demo call, which does have the params "hard coded", but you would just take these values from a UI input...which is simple to do. That may seem like Captain Obvious speaking, but you'll be amazed at some of the data that gets entered into a name field. I then created an If statement to determine how the input data was formatted and whether or not the data is only alphabetic. Sometimes people are just trying to be funny, or they are literally trying to break your program. If the data is indeed only alphabetic letters (no symbols, no numbers or any other punctuation characters) the test succeeds and stores True inside the Name Valid variable. This is because it becomes more legible than just a normal set of numbers.

Add the following inside your name Textbox's Leave event: Private Sub txt Name_Leave(sender As Object, e As System. Leave 'If Not A Matching Format Entered If Not Regex. If you are uncertain about the pattern I supplied, have a look here. Just a note, some surnames contain spaces and even hyphens. Sometimes there are even brackets surrounding the code.

My surname contains a space and it can get quite frustrating if I am not allowed to enter my correct surname, or that I have to edit my surname not to include a space. In certain cases the international dialling code will also need to be supplied. Compiled _ ) Dim bln Possible Match As Boolean = re Email. Text) If bln Possible Match Then 'Check If Entered Email Is In Correct Format If Not txt Email.

So, what I am trying to say is: make sure you understand other cultures, or be aware of people with uncommon names. Using Regular expressions here, is basically the standard, even though it is a bit messy. Focus() 'Return Focus End If End Sub Here, I created a separate function to do all the work.

Ok i am new to biiiiiiiiiiiiiig time, got kind of comfy with vbscript but realise how lazy a coder it makes you. But before you do that you much loop through the search results..user object can be found in the results object.

Anyway i am using 2005 and i have used the built in login form that i would like to use. Close() End Sub Private Sub Cancel_Click(By Val sender As System. Once you have this then you need to loop through it's children and find the group. Ok thought i would share back this code with others. Click Dim isauthenticated As Boolean = Authenticate User() If isauthenticated Then Progress Bar1. Enabled = True 'Msg Box("YOU HAVE BEEN AUTHENTICATED") Dim frm As New Main_Menu frm.
