When trying to generate the crystal report without direct connection string using C# which has UFL functions in the custom formulas, getting below shown error.
Please advise or suggest me where and what I have missed.
Try this sample UFL. Read the info, it specifies how to register it:
And use SP 35 CR for VS:
Note you must run the EXE to integrate into VS, don't install the MSI packages, doesn't work for VS.
Must right click on EXE and select Run as Administrator.
At the end of the install it will prompt for 32 or 64 bit, click OK, you want them both.
