To use the ActiveReports WinForm Viewer to preview report output

1. Add an ActiveReport to your Visual Studio project and rename it rptMain.
2. Add a new "Windows Form" to your project.
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.

To write the code for the viewer in Visual Basic

• Right-click on Form1, and click on View Code to display the code view for the form. At the top left of the code view for Form1, 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 Form1_Load event. Add code to the handler to:
  • Format the viewer to show the report when it is run

To write the code for the viewer in C#

• Click on the blue section at the top of Form1 to select the form. Click on the events icon in the Properties window to display available events for Form1. Double-click Load. This creates an event-handling method for the Form1_Load event. Add code to the handler to:
  • Format the viewer to show the report when it is run

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

  ' Visual Basic
  Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles _
  	MyBase.Load
  	Dim rpt As New rptMain()
  	Viewer1.Document = rpt.Document
  	rpt.Run()
  End Sub

  //C#
  private void Form1_Load(object sender, System.EventArgs e)
  {
  	rptMain rpt = new rptMain();
  	this.viewer1.Document = rpt.Document;
  	rpt.Run();
  }

Note: You need to include references to the RtfExport and TextExport dlls in order to enable the viewer's copy button
