Teach Yourself e.net - Syspro

10
Sample Applications
Objectives - This chapter presents code samples that demonstrate the use of e.net
solutions to create an application using ASP.NET. We have presented these code sections
to help you integrate what you have learned and incorporate it into one programming
environment.
One of the difficulties facing us when trying to learn a new system or programming
language is being able to comprehend the big picture of what can be done with the limited
knowledge that we have of the system or language while we are learning it. As you have
read through this book you have learned the basics of the e.net solutions system and how
to begin programming with it in VBScript, and ASP.NET C# and VB. In this section we
take you one step further by providing some simple applications of the knowledge that you
have gained.
10.1. Simple ASP.NET logon
The first step of any application is to provide a way to logon to the SYSRPO application
server. The following ASP.NET script does this with four user entry text boxes and a
submit button.
Example 10.1. Code Sample for logon.aspx in VB.NET
Sub btnlogon_Click(sender As Object, e As EventArgs)
Dim Util As New Encore.Utilities()
Dim uid As String
uid = Util.logon(tbUser.Text, tbUserPass.Text, tbComp.Text, \
tbCompPass.Text, Encore.Language.ENGLISH, 0, 0, "")
lblUid.Text = uid
Util.Logoff(uid)
End Sub
