Hi

I would like to create a report based on a database query using a windows form programmed with vb.net.

How can I do this using crystal reports in vs.net 2003?

I simply want to query the database and display it in crystal report format on the form.

Thanks

I made all of the reports in crystal reports and saved them off onto a network share in their .rpt format making sure to NOT save data with report when I was complete.
You can hook up whatever database/query to the report at time of creation in crystal reports. Just be sure if you use DNS that the target machine has the same DNS.
I then wrote a small app in VB.net that opens a dialogue box, the user selects the report, it then opens the report using the crystal report viewer the user then puts in their selection criteria into the crystal report (or can you already have your query doing that). All you need to add to your form is the crystal report viewer

Here's the code my app uses:

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim openDialog As New OpenFileDialog
        Me.Cursor = Cursors.WaitCursor
        openDialog.DefaultExt = "rpt"
        openDialog.Filter = "Report Files(*.RPT)|*.rpt|All Files(*.*)|*.*"

        Try
            If openDialog.ShowDialog = Windows.Forms.DialogResult.OK Then
                sReport = openDialog.FileName
                loadReport()
                Me.Cursor = Cursors.Default
            Else
                Me.Cursor = Cursors.Default
                End
            End If

            Me.Cursor = Cursors.Default
        Catch ex As Exception
            MsgBox(ex)
            Me.Cursor = Cursors.Default
            End
        End Try

    End Sub

    Private Sub Form1_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Resize
        cView.Height = Me.Height - 30
        cView.Width = Me.Width - 10
        cView.Left = 0
        cView.Top = 0
    End Sub


    Private Sub loadReport()

        Dim cRpt As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
        cView.ReportSource = sReport
        cRpt.Load(sReport)
        cView.Show()

    End Sub
