Managed Code with Crystal Reports
The Crystal Reports UFLs are not Managed Code in Visual Studio .NET. The UFLs contain functions created in Visual C++ or VB 6, which link into the Crystal Report Designer.
To use a managed code solution with Crystal Reports, use IDAutomation’s C# class library (source code included) to encode the data. This class library will encode the data and add the start, stop, and check characters to the data. The encoded data can be moved directly into the Crystal Report field, which has the appropriate barcode font applied to it.
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.
