I can generate the PDF from the code below:
fdm.frxPDFExport.FileName := 'C:\PASTA_TESTE\ARQUIVO_TESTE.PDF';
frxReport.PrepareReport();
frxReport.Export(fdm.frxPDFExport);
The detail is that it shows me the screen to choose where to save the file.
I would like to save without user intervention, since I have determined the path and file name.
