Object reference not set to an instance of an object.

Crystal Problem : Object reference not set to an instance of an object.

 

The problem is with crystal report web page.

 

The said crystal report web page is working fine upon my development machine but not upon production server.

 

I am using vb.net as code-behind with crystal report bundled.

 

For Example, the following small Crystal report web page is not working upon :->

 

Imports CrystalDecisions.CrystalReports.Engine

Imports CrystalDecisions.Shared

Public Class test

Inherits System.Web.UI.Page

 

Protected WithEvents lblMesg As System.Web.UI.WebControls.Label

Protected WithEvents CrystalReportViewer1 As CrystalDecisions.Web.CrystalReportViewer

 

#Region " Web Form Designer Generated Code "

 

'This call is required by the Web Form Designer.

<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()

 

End Sub

 

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init

'CODEGEN: This method call is required by the Web Form Designer

'Do not modify it using the code editor.

InitializeComponent()

End Sub

 

#End Region

 

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

'Put user code to initialize the page here

If Not IsPostBack Then

lblMesg.Visible = True

lblMesg.Text = "Hello"

End If

End Sub

End Class

 

The Error Message is as below :->

Crystal will only work if the web host company supports them, ask if they do.

[bitelindia]

Although, it is in process to confirm, whether crystal being supported or not upon host from web server administrator.

 

But I have a point, earlier, I was being encountered an error as "can not find keycodev2...error" that has been fixed by me

it indicates that at host there would be crystal reports supported.

 

kindly suggest

 

please help

Can you supply the email or url, the companies who are supporting web cyrstal reports.

 

Is it there is any way to run setup.exe from our side at web server?

 

Our Web host company supports ms visual.net framework and not ms visual studio.net

 

Kindly help
