How do I show a MessageBox when a print job is canceled in FastReport's Print Job Dialog?

推荐答案

当frxReportPrint.Print返回false时，它是用户取消操作或打印错误.因此，您需要检查Errors.Text是否为空，例如:

When frxReportPrint.Print returns false, it is either user cancel or error in printing. So you need to check Errors.Text is empty or not, like:

if not frxReportPrint.Print then
  if frxReportPrint.Errors.Text = '' then
    UserCancel := true
  else
    Abort; // something wrong during printing.
