從vb.net的水晶報表中沒有數據顯示，使用SQL的數據集

Question

我正在使用Vb.Net 2010開發具有水晶報告CRforVS_13_0的項目。我連接到sqlserver並使用以下步驟填充我的數據集。

Imports System.Data.SqlClient 
Imports CrystalDecisions.CrystalReports.Engine 
Imports CrystalDecisions.Shared 
Imports CrystalDecisions.ReportSource 
Imports System.Data 

Public Class frmPrinTest 

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 
    Dim cnn As SqlConnection 
    Dim connectionString As String 
    Dim sql As String 
    Dim MyCommand As New SqlCommand 
    Dim myDA As New SqlDataAdapter 

    connectionString = "Data Source=.\SQLEXPRESS;Initial Catalog=stock;Persist Security Info=True;User ID=sa;Password=1234[enter image description here][1];" 

    cnn = New SqlConnection(connectionString) 
    sql = "select Icode,Iname from stockInvt" 

    MyCommand.Connection = cnn 
    MyCommand.CommandText = sql 
    MyCommand.CommandType = CommandType.Text 
    myDA.SelectCommand = MyCommand 
    Dim ds As New DataSet1 
    myDA.Fill(ds, "stockInvt") 

    Dim objRpt As New CrystalReport1 
    objRpt.SetDataSource(ds) 
    CrystalReportViewer1.ReportSource = objRpt 
    'CrystalReportViewer1.Refresh() 
    End Sub 
End Class 

但我不能在我的數據集或數據表中顯示數據在水晶報告。 我也關注這個鏈接。 CrystalReport_ADO_Dataset PDF 請幫幫我。

你必須指定將使用什麼表水晶報表。所以只要將您的代碼從這個objRpt.SetDataSource(ds)更改爲這個objRpt.SetDataSource(ds.tables("stockInvt"))或objRpt.SetDataSource(ds.tables(0))
