Include a command line argument in RPTrender.exe for displaying the reports automatically without printing. This could be as follows.
Ideally this command line would only bring up the print preview window and when the preview window is closed the software instance would shutdown automatically. Also an command line option is required to which overwrites an instance of the RPTrender.exe in memory in the case where same report is run twice.
Another way of handling report display would be to include some method of allowing display of a report in a listbox with scroll bars, from a report definition. Live Adjustment report parameters on the display would be a useful feature. This would allow the RPTrender to be used within other packages for display reports.
