hi, I'm a newbie of asp.net developer, and I have face a problem when creating a asp.net crystal report. The way i created the crystal report is same as i created in VB
.NET windows desktop application. But it seemed doesn't work in ASP.NET. When the Page_Load() executed, there is an error message shown as "An object is not set as an instance of an object". I know the code is slightly different between asp.net and vb
.net when creating the crystal report.
My environment as below:
1. using Microsoft visual studio.net 2002
2. Database, MS Access 2000
3. WinXP professional (OS)
4. Code below is from the web form
I hope there is someone can provide me some complete example or provide me some guidelines of how to develop crystal report in asp.net if you are experienced in this issue.
Thanks and hope can hear from you all soon.
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
Dim aPrintMonthlyPC As New ReportDocument()
PrintMonthlyPCAdapter1.SelectCommand.CommandText = _
"SELECT * FROM Employee "
Dim aPrintMonthlyPC As ReportPrintMonthlyPC
aPrintMonthlyPC = New ReportPrintMonthlyPC()
Me.PrintMonthlyPCViewer1.DisplayGroupTree = True
Me.PrintMonthlyPCViewer1.ReportSource = aPrintMonthlyPC
