广彩大清出口瓷器:（急救）关于CrystalReport显示不出数据问题。。。。。

1.Access+DataSet+CrystalReport
2.通过DataGridView1可用显示数据。
3.在CrystalReportViewer1显示空数据。

dataset数据集

报表设计

最后显示结果，DataGridView1显示正常 ，报表却是空白数据。

代码如下：

Public Class CrystalReportViewer

Private myCon As OleDbConnection
Private mySelect As String
Private myDataAdapter As OleDbDataAdapter
Private objDataSet As DataSet1
'DataSet1是DataSet1.xsd文件
Private myconnstring As String = My.Settings.ryglConnectionString
'My.Settings.ryglConnectionString 是配置文件
Private objPersonCrystalReport As CrystalReport2
'CrystalReport2是我建立的一个CrystalReport2.rpt

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

selectinfo="select * from person"
myCon = New OleDbConnection("")
myCon.ConnectionString = myconnstring
myDataAdapter = New OleDbDataAdapter(mySelect, myCon)
objDataSet = New DataSet1
myDataAdapter.Fill(objDataSet, "PersonCR")

objPersonCrystalReport = New CrystalReport2
objPersonCrystalReport.SetDataSource(objDataSet.Tables("PersonCR"))
DataGridView1.DataSource = objDataSet.Tables("PersonCR")
'DataGridView1显示正常。
PersonCrystalReport.ReportSource = objPersonCrystalReport
End Sub
