This topic explains how to migrate the ActiveX viewer included in ActiveReports 3, 2, and 1.
In ActiveReports 6 or above, ActiveX viewer (ARVIEW2.CAB) is not provided with the product installer. You need to migrate a web application that includes ActiveX viewer on the Web form or contains the WebViewer with ViewerType property set to ActiveXViewer. In ActiveReports 18, you can use the PDF export feature instead of ActiveX Viewer.
If the ViewerType property is set to ActiveXViewer, you need to change it to AcrobatReader. For example, modify the code marked in red like the following code.
Before migration
Visual Basic |
Copy Code
|
---|---|
' Set the type of the selected view in ViewerType property of the WebViewer. Dim selection As String = Me.cboViewerType.Items(Me.cboViewerType.SelectedIndex).Text Select Case selection Case "AcrobatReader" Me.arvWebMain.ViewerType = DataDynamics.ActiveReports.Web.ViewerType.AcrobatReader Case "ActiveX viewer" Me.arvWebMain.ViewerType = DataDynamics.ActiveReports.Web.ViewerType.ActiveXViewer Case "HTML viewer" Me.arvWebMain.ViewerType = DataDynamics.ActiveReports.Web.ViewerType.HtmlViewer Case "RawHtml" Me.arvWebMain.ViewerType = DataDynamics.ActiveReports.Web.ViewerType.RawHtml End Select |
C# |
Copy Code
|
---|---|
// Set the type of the selected view in ViewerType property of the WebViewer. { string selection = this.cboViewerType.Items(this.cboViewerType.SelectedIndex).Text; switch (selection) { case "AcrobatReader": this.arvWebMain.ViewerType = DataDynamics.ActiveReports.Web.ViewerType.AcrobatReader; break; case "ActiveX viewer": this.arvWebMain.ViewerType = DataDynamics.ActiveReports.Web.ViewerType.ActiveXViewer; break; case "HTML viewer": this.arvWebMain.ViewerType = DataDynamics.ActiveReports.Web.ViewerType.HtmlViewer; break; case "RawHtml": this.arvWebMain.ViewerType = DataDynamics.ActiveReports.Web.ViewerType.RawHtml; break; } } |
After migration
Visual Basic |
Copy Code
|
---|---|
' Set the type of the selected view in ViewerType property of the WebViewer. Dim selection As String = Me.cboViewerType.Items(Me.cboViewerType.SelectedIndex).Text Select Case selection Case "AcrobatReader" Me.arvWebMain.ViewerType = GrapeCity.ActiveReports.Web.ViewerType.AcrobatReader Case "HTML viewer" Me.arvWebMain.ViewerType = GrapeCity.ActiveReports.Web.ViewerType.HtmlViewer Case "RawHtml" Me.arvWebMain.ViewerType = GrapeCity.ActiveReports.Web.ViewerType.RawHtml End Select |
C# |
Copy Code
|
---|---|
// Set the type of the selected view in ViewerType property of the WebViewer. { string selection = this.cboViewerType.Items(this.cboViewerType.SelectedIndex).Text; switch (selection) { case "AcrobatReader": this.arvWebMain.ViewerType = GrapeCity.ActiveReports.Web.ViewerType.AcrobatReader; break; case "HTML viewer": this.arvWebMain.ViewerType = GrapeCity.ActiveReports.Web.ViewerType.HtmlViewer; break; case "RawHtml": this.arvWebMain.ViewerType = GrapeCity.ActiveReports.Web.ViewerType.RawHtml; break; } } |
Re-create the application by referring the following basic operation or sample. Note that you don't need to re-create everything.
The basic difference between ActiveX viewer and PDF export is in the format of the data received from the web server to the client. An RDF file is generated on the Web server with ActiveX viewer and binary data of PDF format is created on the web server with PDF export. The other operations are common in ActiveX viewer and PDF export, there is no need to re-create the existing applications that are created using the ActiveX viewer. See CustomPreview sample for more information.
