Dateset中的数据无法加载至报表并显示出来，以下是我的代码：（myReportDoc.SetDataSource(ds)中ds里是有数据的）
Imports System.Data.SqlClient
Imports CrystalDecisions.CrystalReports.Engine

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim myconnection As New SqlConnection("SERVER=Local;database=jiankong;uid=sa;pwd=")
Dim mycommand As SqlDataAdapter
Dim ds As DataSet = New 监控
Dim stringsql As String
stringsql = "select * from zidongjiankong where (occur_day> =('" + 开始日期 + "') and occur_day<=('" + 结束日期 + " ')) "

mycommand = New SqlDataAdapter(stringsql, myconnection)
Try
mycommand.Fill(ds, "jk")
Catch ex As Exception
MessageBox.Show(ex.ToString)
End Try

Dim itest As Int32 = ds.Tables("jk").Rows.Count
Dim myReportDoc As New ReportDocument
Try
myReportDoc.Load(Application.StartupPath & "\监控日志.rpt")
Catch ex As Exception
MessageBox.Show(ex.ToString)
End Try
myReportDoc.SetDataSource(ds)
CrystalReportViewer2.ReportSource = myReportDoc
End Sub

Dim ds As DataSet = New 监控 ??這是什麼意思
DataSet不是自己定義的吧，是已經存在的DataSet1.xds

我给自已定义的DataSet和和数据集DataSet1搞晕了~!有的表用Dataset没问题,有的用又不行,而有的又用Dataset1就可以~
