I am using the Crystal Reports v10 VCL component (with C++ Builder 6) to setup and generate my reports but when I try to set the formulas at run time using the code samples supplied with the Crystal Reports help I get Access Violation errors when accessing the Formula Properties. He is an example: CrpeTest->ReportName = "My Report Name"; CrpeTest->FormulaByName("MyFormulaName")->Formula->Text = "My Formula Value"; CrpeTest->Execute(); The code generates and ACCESSS VIOLATION when trying to set the formula... has anyone else seen this and know how to fix it? Thanks Scott Back to top Scott Kent-Collins Guest Posted: Sun Feb 20, 2005 9:56 pm    Post subject: Re: VCL Formula Access Violation. OK, some further testing shows that the DELPHI version of the code and Crystal VCL component works fine. It is only the C++ Builder 6 version that has problems. I think it is because the "UCrpe32.hpp" file that Crystal supplied is incorrect/corrupted and does match the "UCrpe32.pas" file. Is there and easy way to regenerate the HPP file based on a PAS file?
