This walkthrough is split up into the following activities:

• Adding a new Windows Form and ActiveReports WinForm viewer control
• Adding code for the viewer's setReport event
• Adding code for the viewer's showReport event
• Adding code for frmPrintPreview Load event

Adding a new Windows Form and ActiveReports viewer control

To add a new form and viewer control

1. Add a new "Windows Form" to your Visual Studio project.
2. Change the name of Form1 to frmPrintPreview.
3. Click on the ActiveReports viewer control in the appropriate toolbox and drag it onto Form1.
4. Set the viewer control's Dock property to Fill.

Adding code for the viewer's SetReport event

To write the code in Visual Basic

• Right-click in any section of frmDesigner, and click on View Code to display the code view for the Windows Form. Add the following code to create the SetReport event.

To write the code in C#

• Double-click on frmDesigner to see the code view for the Windows form. Add the following code to create the SetReport event.

  The following example shows what the code for the method looks like.

  ' Visual Basic
  Public Sub SetReport(ByRef report As DataDynamics.ActiveReports.ActiveReport)
          Try
              m_rpt = report
          Catch ex As Exception
              MessageBox.Show("Error: " + ex.Message + "\n" + "Stack:\n" + ex.StackTrace + _
  	"\n" + ex.Source)
          End Try
  End Sub

   

  //C#
  public void SetReport(DataDynamics.ActiveReports.ActiveReport report)
  {
  	m_rpt = report;
  }

Adding code for the viewer's showReport event

To write the code in Visual Basic

• Right-click in any section of frmDesigner, and click on View Code to display the code view for the Windows Form. Add the following code to create the showReport event.

To write the code in C#

• Double-click on frmDesigner to see the code view for the Windows form. Add the following code to create the showReport event.

  The following example shows what the code for the method looks like.

  ' Visual Basic
  Private Sub showReport(ByRef reportObject As DataDynamics.ActiveReports.ActiveReport)
          Try
              Dim rpt As New DataDynamics.ActiveReports.ActiveReport()
              rpt = reportObject
              Me.Viewer1().Document = rpt.Document
              rpt.Run()
          Catch ex As Exception
              MessageBox.Show("Error:\n " + ex.Message + "\nStack:\n" + ex.StackTrace + _
  	"\nSource:\n" + ex.Source)
          End Try
  End Sub

   

  //C#
  private void showReport(DataDynamics.ActiveReports.ActiveReport report)
  {
  	try
  	{
  		DataDynamics.ActiveReports.ActiveReport rpt = 
  			(DataDynamics.ActiveReports.ActiveReport)report;
  		viewer1.Document = rpt.Document;
  		rpt.Run();
  	}
  	catch(Exception ex)
  	{
  		MessageBox.Show("Error:\n " + ex.Message + "\nStack:\n"+ _
  			ex.StackTrace + "\nSource:\n" + ex.Source);
  	}
  }

Adding code for the frmPrintPreview_Load event

To write the code in Visual Basic

• Right-click on frmPrintPreview, and click on View Code to display the code view for the form. At the top left of the code view for frmPrintPreview, click the drop-down arrow and select (Base Class Events). At the top right of the code window, click the drop-down arrow and select Load. This creates an event-handling method for the frmPrintPreview_Load event.

To write the code in C#

• Click on the blue section at the top of frmPrintPreview to select the form. Click on the events icon in the Properties window to display available events for frmPrintPreview. Double-click Load. This creates an event-handling method for the frmPrintPreview_Load event.

  The following example shows what the code for the method looks like.

  ' Visual Basic
  Private Sub frmPrintPreview_Load(ByVal sender As System.Object, ByVal e _
  	As System.EventArgs) Handles MyBase.Load
          If m_rpt Is Nothing = False Then
              Me.showReport(m_rpt)
          End If
  End Sub

   

  //C#
  private void frmPrintPreview_Load(object sender, System.EventArgs e)
  {
  	if(m_rpt != null)
  	{
  		this.showReport(m_rpt);
  	}
  }
