Visual Basic

hello dear all the best programmer,

this is my first posting or maybe a question but hopely although i am the beginner and newbie in vb .net you would like to help for solving my problem.

i get some problem when i was making a report application with crystal report in vb.net using sql server database. i make simple application that consist one button "show report" and one crystal report viwer. i put code to the button "show report" :
<pre lang="vb">Imports CrystalDecisions.CrystalReports.Engine

Public Class Form1

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim cryRpt As New ReportDocument
        cryRpt.Load(&quot;Data Source=(localdb)\Projects;Initial Catalog=crystaldb;Integrated Security=True&quot;)
        CrystalReportViewer1.ReportSource = cryRpt
        CrystalReportViewer1.Refresh()

    End Sub

End Class</pre>



and when i run the program, actually there is no problem but why i must first ly to do an action login. the action login consist of some field , they are server name, databse , id and pasword. the server name was automatically filled and the database field was empty and but i can't fill in it. and for id and password that were empty to and i must and able to fill that.

for the id and pasword field, i don't know what thing i must to fill in that field. hopely anybody can understand my question and problem clearly and as soon as possible would like to help me.


thanks and best regards,
