First and foremost, this is a VB.Net question (Not ASP.Net since you are using Win Forms) second in your app.config you need a < connectionStrings > < /connectionStrings > section (like below) then add your connection string as I have. The weird thing about your post is you ask how to make it work in the app.config in Windows Forms then you ask how to call it on every "page" taht needs it, Windows Forms dont have "pages". The below example will work in Windows Forms (which is what you asked).
As for the 2nd part of your question, the easiest way to call it is to write a function like below:
'This returns the connection string
Public Shared Function GetConnectionString(ByVal strConnection As String) As String
Dim strReturn As New String("")
'If you have multiple connection strings then you can pass it a connection name otherwise it defaults to your default connection
If Not String.IsNullOrEmpty(strConnection) Then
strReturn = ConfigurationManager.ConnectionStrings(strConnection).ConnectionString
Else
strReturn = ConfigurationManager.ConnectionStrings("MyConnectionName").ConnectionString
End If
Return strReturn
End Function
Then on the form that needs a DB connection call it like this:
Dim oConnection As New SqlConnection(YourClassName.GetConnectionString("MyConnectionName"))
<connectionstrings>
<add name="MyConnectionName">
connectionString="Persist Security Info=False;Data Source=localhost;Initial Catalog=db;Integrated Security=SSPI;Trusted_Connection=TRUE;Application Name=AppName"
providerName="System.Data.SqlClient" />
</add>
</connectionstrings>
If you mis-worded your question and need this for an ASP.Net application (not Windows Forms) reply and let me know and I'll help as much as I can

I made a page using CreateUserWizard but I restrict it for Admins only. The problem is when an Admin create an account for the new user, after completing the steps, it automatically change the logged in Admin to the new created account. Is there anyway not to login after creating an account? Except for the Security setup wizard on ASP.NET Configuration. 
Thanks!

I'm using Visual Studio 2005 and I'm writing ASP.Net pages. CreateUserWizard is very easy to use but I don't know how to change the settings so that after creating a new User, it will not automatically log-in on the user... Only Admins could create a new user.

You'll need to embedd an activeX or .NET control into your page in order to offer this functionality, you can't do it otherwise.

A button event generates a postback. There is no way you're getting two click events for one click, there's something wrong in your code. Try posting it.

Whenever I try to connect to the PUBS.MDF database, a login failed error message will appear.
I defined the connection string in the web.config file under the connectionstrings section like this:
[code]
add name="Pubs" connectionString="Data Source = localhost\SQLEXPRESS; Initial Catalog=Pubs;Integrated Security=SSPI"
[/code]
And setup the connection in the click event of a button:
[code]
Dim connectionString As String = WebConfigurationManager.ConnectionStrings("Pubs").ConnectionString
Dim myConnection As New SqlConnection(connectionString)
myConnection.Open()
..........
[/code]
And I put the PUBS.MDF file in the same folder as the vb source files.
How do I connect to the database correctly?

This looks for a named instance of SQL Server called SQLEXPRESS, and then tries to find a DB called pubs in there. It sure as hell isn't going to find a file called 'pubs.mdf' ( which is an access database )

Not sure exactly what you mean - for a client to download a program, they need to request it from a web page, or connect to a site via an FTP program. You can't download a program without a program on the client end attempting the download, via HTTP or FTP, or via a web service call ( which is HTTP anyhow )

1 - never post personal messages as new posts, the odds are that navneeth won't see this, because of other posts that will occur
2 - Goodness knows what you're talking about here. I am sure the terminology he used was correct, it's not his fault you didn't understand it ( assuming I've read you right ).
3 - If you google, you'll find out how to use regex in javascript, it's widely documented.

Hi, the following code shows how to write Binary files to the browser using ASP.NET.
<br />
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)<br />
'Set the appropriate ContentType.<br />
Response.ContentType = "Application/pdf"<br />
'Get the physical path to the file.<br />
Dim FilePath As String = MapPath("acrobat.pdf")<br />
'Write the file directly to the HTTP content output stream.<br />
Response.WriteFile(FilePath)<br />
Response.[End]()<br />
End Sub<br />
Do I need the line Response.ContentType = "Application/pdf" in order to write the binary files to the browser? If so, how do I modify it so that it would aslo support other binary file types? Please show a sample code if you can. Thanks for your help.

If it's a PDF, yes.

Google for the list of MIME types that IE supports, and change your text according to the file type you're trying to send.
