vb 水晶报表打印

vb里面的水晶报表打印控件：CrystalReportViewer

用到的dll文件：

水晶报表打印其实很简单，只要创建报表对象，再对其传递数据就可以打印出来。当然所传递的数据要与水晶报表设计里面的数据一致：

Public Overloads Sub ShowDialog(ByVal netDs As DataSet, ByVal strPath As String, Optional ByVal showPrint As Boolean = True, Optional ByVal showExport As Boolean = True)
        Try
            If netDs.Tables(0).Rows.Count > 0 Then
                Dim rpt As New ReportDocument
                rpt.Load(strPath)
                rpt.SetDataSource(netDs)

                CRV.ReportSource = rpt
                CRV.ShowPrintButton = showPrint
                CRV.ShowExportButton = showExport
                Dim t As New ComboBox
                t.Visible = True
                ShowDialog()
            Else
                MsgBox("Not print Data！", MsgBoxStyle.Critical)
            End If
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
    End Sub

调用例子：在其他设计界面，当要打印之时，直接传递参数到打印界面即可。

Dim daOM As SqlDataAdapter
    Dim cmbOM As SqlCommandBuilder
    Dim dsOM As New DataSet

    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Try
            daOM = New SqlDataAdapter("select top 5 * from facd321 ", GetConn)
            cmbOM = New SqlCommandBuilder(daOM)

            daOM.Fill(dsOM, "OM")

            With dg
                .DataSource = dsOM.Tables("OM")
                .WindowLaguage = myDataGrid.myDatagrid.LanguageType.English
                .FilterBar = True
                Dim ii As Int16
                For ii = 0 To .Splits(0).DisplayColumns.Count - 1
                    .Splits(0).DisplayColumns(ii).Locked = True
                Next
            End With
        Catch ex As Exception
            MsgBox(ex.Message, MsgBoxStyle.Exclamation, "Error")
        End Try
    End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            Me.Cursor = Cursors.WaitCursor

            Dim f As New Form1
            AddBarcodeImages(dsOM.Tables(0))
            f.ShowDialog(dsOM, Application.StartupPath & "Reportsundle.rpt")
        Catch ex As Exception
            MsgBox(ex.ToString)
        Finally
            Me.Cursor = Cursors.Default
        End Try
    End Sub
