The first error hit: E2003 Undeclared identifier: 'Canvas' in QRPrinter.pas . Delphi 11 UPD had changed the accessibility of the TCanvas object in the TPrinter device context. The old code was poking directly at memory handles that UPD had politely locked away for security.
Perfect.

Marco Santini stared at the Delphi 11 Alexandria IDE, the blue glow of his monitor the only light in the office at 11:47 PM. The deadline for the accounting module’s reporting suite was 8:00 AM. And QuickReport—the venerable, crusty, old-warhorse reporting engine—was throwing a fit. Quickreport For Delphi 11 Alexandria UPD
Or he could do what real Delphi developers do:
{$IFDEF DELPHI11_UPD} // Use legacy GDI calls for backward compatibility DrawTextA(Canvas.Handle, PAnsiChar(AnsiString(Text)), -1, Rect, DT_LEFT); {$ELSE} // Normal modern code Canvas.TextOut(X, Y, Text); {$ENDIF} At 3:45 AM, the compile succeeded. No errors. No warnings. The EXE was built.
He leaned back, the ergonomic chair groaning in sympathy. The problem wasn't just that QuickReport was broken. The problem was that QuickReport was abandoned . The last official update for Delphi 11 had been a community patch held together with duct tape and anonymous FTP links. The official Qusoft site hadn't been updated since 2015. The first error hit: E2003 Undeclared identifier: 'Canvas'
He ran the application. He clicked "Print Preview."
His hands hovered over the keyboard. He could rewrite the entire reporting module in FastReport. That would take three weeks. He could export everything to PDF via a third-party library. That would take two days, but the client’s internal audit required raw, printable QRP formats.
uses Winapi.Windows, Vcl.Graphics, Vcl.Printers, QRPrinter; Perfect
He commented out the entire DrawText block. He replaced it with TTextMetric calls that were deprecated in Windows 10 but still worked . He added compiler directives:
Marco wasn't just a developer; he was the caretaker of legacy. He’d inherited the Silverpoint Logistics codebase from three generations of programmers who had all sworn the same oath: “Don’t touch the reports.”
He recompiled the entire QuickReport source with this patch injected. The E2003 vanished. But then came the avalanche: E2010 Incompatible types: 'HPEN' and 'TFont' in QRExpImg.pas . The image exporter was trying to use GDI pens on GDI+ fonts. UPD’s updated TMetafile handling had stricter type checking.
It was a memory leak waiting to happen. He didn't care. It was 1:30 AM.
Marco picked up a red marker, crossed it out, and wrote underneath: "No. We can't even migrate it to a patch."
