At 1:15 AM, he wrote a dirty, beautiful hack. He created a new unit, QRCompatPatch.pas :
Or he could do what real Delphi developers do:

It was a memory leak waiting to happen. He didn't care. It was 1:30 AM.
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.
He ran the application. He clicked "Print Preview." Quickreport For Delphi 11 Alexandria UPD

At 12:03 AM, Marco opened the source. Not the application source—the QuickReport source. He’d kept a copy of the full source code for QuickReport 6, a relic from the CodeGear era. He dropped the QR6 folder into his project’s search path, bypassing the precompiled DCUs provided by the GetIt package manager.
The screen flickered. For one gut-wrenching second, the report preview was a scrambled mess of pixels and overlapping fonts. His heart sank. Then, as if waking from a coma, the TQRPreview component redrew itself. Line by line. Invoice number, date, item description, amount. function TQRPrinterHack
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.
type TQRPrinterHack = class(TQRPrinter) private function GetCanvasHack: TCanvas; public property CanvasHack: TCanvas read GetCanvasHack; end;
Marco exhaled. He saved the modified QuickReport source to a new folder: QuickReport_D11_UPD_Stable . He zipped it. He uploaded it to the company’s internal NuGet-style Delphi repository. He added a single comment in the team’s commit log: Patched QuickReport for Delphi 11 UPD. Replaced direct Canvas access with Win32 DC handle hack. Disabled GDI+ type checking in QRExpImg. Use {$DEFINE DELPHI11_UPD} in project settings. Works on my machine. Don't touch. He closed the IDE. The clock on the wall said 5:14 AM. He had just enough time for a double espresso before the client’s 8:00 AM validation call. He created a new unit, QRCompatPatch
He smiled. Delphi wasn't dead. It was just... veteran . And so was he.
