John Kouraklis last week announced a new book: MVVM in Delphi.
It will be available early november and is already listed at the APress site: MVVM in Delphi – Architecting and Building Model View ViewModel Applications [WayBack] where you can pre-order.
It’s good to see that the last years more Delphi books have been published and I hope this MVVM book falls in the more advanced category.
Since I’ve given a few Delphi MVVM talks (latest at https://github.com/jpluimers/Conferences/tree/master/2013/20131121-BE-Delphi) I’m genuinely interested. So I will get this book and – time permitting – write a review.
Nick Hodges did the technical review, and since Nick’s book are great I have high hopes (:
From the APress site:
Full Description
Dive into the world of MVVM, learn how to build modern Windows applications, and prepare for cross-platform development. This book introduces you to the right mindset and demonstrates suitable methodologies that allow for quick understanding of the MVVM paradigm. MVVM in Delphi shows you how to use a quick and efficient MVVM framework that allows for scalability, is of manageable complexity, and provides strong efficiency.
One of the biggest challenges developers face is how to convert legacy and monolithic Delphi applications to the MVVM architecture. This book takes you on a step-by-step journey and teaches you how to adapt an application to fit into the MVVM design.
What you’ll learn
- Gain the fundamentals of MVVM
- Visualize MVVM as a design philosophy
- Create easy-to-use frameworks for building your own MVVM applications
- Develop a methodology for converting legacy applications to the MVVM pattern
- Architect cross-platform and multi-lingual applications using the MVVM pattern
Who this book is for
Delphi developers with a good knowledge of Delphi or programming experience in a different language. In addition, this book is attractive to Delphi developers who want to modernize existing applications based on the MVVM design.
and
Table of Contents
1. MVVM as Design Pattern
2. Setting Up the POSApp
3. MVVM as Design Philosophy
4. Two-way Communication
5. MVVM and Delphi
6. Planning the Application
7. Developing the Application
8. How to Convert your App to MVVM
A. Appendix: Other MVVM Delphi frameworks

I’ve published the Delphi version info table as a Gist: https://gist.github.com/jpluimers/b5891600b73642788b492393710c6070.
Note I need help with these:
The updated script that forms the base of this table is here: https://bitbucket.org/jeroenp/wiert.me/src/tip/Native/Delphi/Scripts/List-Delphi-Installed-Packages.ps1
You can pass any of these args to get information
An elaborate wrapper around the Define column is jedi.inc which is used in many projects (both open source and closed source) to distinguish between various Delphi versions, libraries and platforms at compile time (URL: github.com/project-jedi/jedi/blob/master/jedi.inc)

Thanks Primož Gabrijelčič for reminding me on Stack Overflow that Alt + Down opens the dialogs behind ellipsis buttons in the Delphi IDE.
It’s the CUA and Windows short-cut to open drop-down lists (comboboxes) and for opening drop-down list for a property in the object inspector, but I never realised also would work for these ellipsis buttons.
This was my original stack-overflow question: Is there a keyboard shortcut for the ellipsis buttons of the Project Options in the Delphi IDE?
The Project Options in the Delphi IDE has a few option (like the
Search Path) each with an ellipsis button (the one on the right having only three dots...in the image below) to pop-up a dialog.What keyboard shortcut activates that button?

Recently when printing the 3rd time and up, you get this error in many Delphi programs and the Delphi IDE:
Printer is not currently printing.
In the past this only occurred when you used a TPrinter and forgot to call BeginDoc.
But now it always occurs after reusing the same TPrinter instance for the 3rd time and up. Since the Delphi Galileo based IDEs (8 and higher; likely older ones as well: the source code printing hasn’t changed in a long time). The error actually occurs twice: after starting a source code print job, but also after cancelling the same failed source code print job.
The second error stroke me as odd, so I went searching for “printer is not currently printing” “IDE” leading to this stack overflow question: c++builder – Why is TPrinter (XE7) suddenly having problems today? – Stack Overflow [WayBack].
The pattern there is using the
Printer()function which has been the way the (un)official code examples have shown for ages (Delphi 2007 Printers.Printer Function [WayBack]; earlier examples like Delphi 7 [WayBack] usually in PDF files).Like in the Delphi 7 “5-32 Developer’s Guide” page example:
procedure TForm1.Button1Click(Sender: TObject); var r: TRect; i: Integer; begin with Printer do begin r := Rect(200,200,(Pagewidth - 200),(PageHeight - 200)); BeginDoc; Canvas.Brush.Style := bsClear; for i := 0 to Memo1.Lines.Count do Canvas.TextOut(200,200 + (i * Canvas.TextHeight(Memo1.Lines.Strings[i])), Memo1.Lines.Strings[i]); Canvas.Brush.Color := clBlack; Canvas.FrameRect(r); EndDoc; end; end;(Yes, that’s back in the D7 days when examples were still using with and not using try/finally statements for resource cleanup).
The printing problems are caused by various recent Windows updates part of MS16-098:
Though MS16-098: Security update for Windows kernel-mode drivers: August 9, 2016 mentions the issue without a fix, KB3177725 in MS16-098: Description of the security update for Windows kernel-mode drivers: August 9, 2016 mentions both the issue and a permanent fix:
After you apply this security update and you print multiple documents in succession, the first two documents may print successfully. However, the third and subsequent documents may not print.
To resolve this issue, install update 3187022. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
3187022 Print functionality is broken after any of the MS16-098 security updates are installed
This article describes printing issues that occur after any of the security updates that are described in Microsoft Security Bulletin MS16-098 are installed in Windows. You can fix these issues by installing the update that is described in this article. Before you install this update, check out the Prerequisites section.
This update applies to the following operating systems:
- Windows Server 2012 R2
- Windows 8.1
- Windows RT 8.1
- Windows Server 2012
- Windows Server 2008 R2 Service Pack 1 (SP1)
- Windows 7 SP1
- Windows Server 2008 Service Pack 2 (SP2)
- Windows Vista SP2
No solution for Windows 10 yet…
For your own code (Thanks Remy Lebau for your answer), add this code for your BeginDoc call:
MyPrinter.Copies := MyPrinter.Copies;
You might want to keep including this in your code as you’re never sure when the end-users apply which Windows update.
For the Delphi IDE either:
Print Selection dialog
“Print Setup” dialog.
Security Update for Microsoft Windows (KB3177725)
