    In This Topic

    The ActiveReports provides the Windows Forms Viewer application ActiveReports.Viewer.exe, bundled with the ActiveReports installer. The app can be launched by installing the ActiveReports installer package.

    You can run the application by selecting the ActiveReports 18 Viewer from the Start menu, or by running the ActiveReports.Viewer.exe from the C:\Program Files (x86)\MESCIUS\ActiveReports 18\Tools\ location.

    Report readers wanting to quickly preview a report in WinForms platform can use WinViewer sample. You just need to load the report you want to view in the viewer control. The Windows Forms Viewer with a report loaded looks like the following.

    WinForms Viewer

    The Windows Forms Viewer is basically a Windows Forms application with an ActiveReports Viewer control in it. The default user interface of this application provides an ActiveReports Viewer control along with a menu bar.

    You can open a .rdlx or .rpx report in the standalone viewer application, by going to the File menu > Open menu option and selecting a report to load in the viewer. Unlike the Viewer control, no code implementation is required to load the report in the standalone application.

    Please note that any additional features activated through code like the annotation toolbar, are not available in the standalone viewer application.
