Error detected in export .dll - Crystal Reports
When exporting Crystal Reports to a .pdf format, the great error message "Error detected in export .dll" started popping up. It took a while to track down, but the cause was this:
An image field was on the report, but the data was null. Worked fine in the viewer, but just not on the export.
Set "Suppress" to isnull(image_field_here).

If the problem persists, (the error msg), it could be because the particular image that is being displayed is incompatible (unknown) to the export utility and/or report. For example, if there IS data in the field (is not null), it could be BAD data or an incompatible image type. Check to see if 'isnull(image_field_here)' returns false. If so, open the image (from the image data) in paint, save as a plain .jpg (also try .bmp) and reupload to the report and try exporting again. Certain image types are not handled by the export utilities, and will give this error.
