cViewIMAGE.SingleImage | Operation | Sample report This is the recommended driver for processing a single image file name. It was developed after feedback from our users. This driver is fast and easy to use. Create a new report or subreport, and select a COM data source. In CR8.5 this is listed in the data explorer under "More Data Sources", "Active Data". If you do not see COM data listed, you can install the COM driver using these instructions.
Specify a COM Program ID of cViewIMAGE.SingleIMAGE.
You will then be prompted for the name of an image file.
This can be used to retrieve a single image in a main report, but would be more useful in a subreport where the parameter was loaded from a field or formula in the main report.
A sample report and data has been included with this application. The report is SingleImage.rpt and uses the Images.MDB table. You are welcome to add your own images to this database. The only difficult thing to do with this report was linking the field in the main report to the cViewIMAGE parameter asking for the file name. By default Crystal Reports wants to create a new parameter in the subreport. You must override this, and select the ?ImageFile parameter using a very small scroll box.
