  Sorry guys, i close this topic.
  
  I've found what causes the problem, it is function GetFieldNames from my own component.
  
  Thanks anyway.

  Hi,
  
  I designed my own TDataset descendant component, i have planned to use FastReport for data reports. I am trying to play with it to see how it works, i found an error when generating preview. When i investigate it, the error come from event AfterOpen on unit data.db.
  
  So my question, What procedure or function should i provide in my component to make it compatible with FastReport.
  
  Almost forget to mention, i use fastReport 4.6 that comes with Delphi XE2.
  
  Below is the error message,

  Debugger Exception Notification

  Project Project1.exe raised exception class $C0000005 with message 'access violation at 0x004082b3: read of address 0xbaadf00d'.
  
  
  
  Thanks.
