Barcode had all Zeros in Crystal Reports
When a barcode displays all zeros, it means that invalid data has been passed through the function. The latest version of the IDAutomation Crystal UFL will now usually create a barcode containing all zeros rather than causing the report to shut down.
Additionally, IDAutomation offers Crystal Font Formulas, which embed directly into the report. The formulas may solve any UFL related issues because the UFL is not required when they are used.
