Visual Basic and Crystal Reports
Note: 32-bit Support Only. U2LCOM.DLL is a 32-bit UFL only and, therefore, supports only 32-bit Automation Server DLLs. To create User-Defined Functions for Crystal Reports, you must have the 32-bit edition of Visual Basic 4.0 or Visual Basic 5.0 (or another 32-bit development environment that supports the creation of COM-based Automation Servers).
