eWriter Help System for Delphi / RAD Studio

(Update December 2022 for eViewer 3.x)

[All Delphi versions from XE]

eWriter Viewer

This is an implementation of the eWriter help format as a replacement for HTML Help (.chm) files in Delphi applications.

EWriter eBooks are the modern alternative to the obsolete CHM format for local application help. They offer full support for context-sensitive help and file links. They combine the benefits of CHM and WebHelp and eliminate the disadvantages of both.

The package includes the unit Vcl.EwriterHelpViewer.pas which implements support for the eWriter help format in Delphi's help system. Applications currently using CHM files for application help can switch to eWriter help with basically no changes.

Zooming in on HTML Help: Get Microsoft HTML Help (.chm) ready for 4K!

(Released June 2015)

This tutorial focuses on application documentation in HTML Help (.chm) format and is made for all Windows developers, whether you work with Visual Studio or Delphi or any other Windows desktop development tool.

DPI-awareness: when your application is 4K-ready

DPI-awareness is when you have prepared your Windows desktop application to shine on ultra-high resolution ("4K") monitors. It needs a lot of details to make this work well. Once your application is DPI-aware, the Microsoft HTML Help viewer invoked via the HTML Help API, will be DPI-aware, too! With unexpected consequences...

In this tutorial, you learn what to take care of in HTML Help on 4K monitors, what to avoid, and how to get things right!

OpenOffice 3 Spell Checker for Delphi

Version: 1.1  (updated March 2011)

Open source component to implement spell checking using OpenOffice 3 dictionaries.


This is a spelling checker based on the NHunspell project from Thomas Maierhofer (also open source). It is the first Delphi implementation to directly support the latest OpenOffice 3 dictionaries and uses the Hunspell spell checking engine, which is being used in OpenOffice, Firefox and many other software programs.
