EditControls Documentation

Introduction

EditControls is a collection of edit control-like ActiveX controls. The HotKeyBox control wraps the msctls_hotkey32 window class, the IPAddressBox control wraps the SysIPAddress32 window class, the TextBox control wraps the Edit window class and the UpDownTextBox control combines the Edit and msctls_updown32 window classes.
The controls are optimized for Visual Basic 6.0, but should also work in any other environment that supports COM controls.

Basics

The controls superclass the mentioned native window classes of Windows: msctls_hotkey32, SysIPAddress32, Edit and msctls_updown32. Although I tried to wrap all features of these window classes (status: Windows 10), some things may be missing. In these cases you usually may use the Win32 API and handle the controls as native windows of the corresponding class. One of my goals was it to create controls that may be controlled via API as well as via the classes that I implemented.

Requirements

EditControls Unicode runs on the following operating systems:

  • Windows XP (SP3 or later)
  • Windows Server 2003 (SP2 or later)
  • Windows Vista (SP2 or later)
  • Windows Server 2008 (SP2 or later)
  • Windows 7 (SP1 or later)
  • Windows Server 2008 R2 (SP1 or later)
  • Windows 8
  • Windows Server 2012
  • Windows 8.1
  • Windows Server 2012 R2
  • Windows 10
  • Windows Server 2016
  • Systems supported by Wine (Wine is a Win32 subsystem for alternative operating systems) - limited support
  • ReactOS (a free Windows XP clone) - limited support

Some features have additional requirements which are mentioned in the affected feature's documentation.
Limited support means, that I won't invest much work to support those systems. If a feature works on a system tagged with "limited support" - fine; if it does not and it's easy to fix, I'll fix it, but if it's difficult to fix, I probably won't fix it. Also I will test the control much less on those systems.

Support

There's no entitlement to support. Period. However, you have good chances to get help if you post your questions on GitHub or in the forums.
Also the project is open source, so feel free to have a look at the source code. You may modify it, but please consider sharing your changes with the rest of the world.

FAQ

1. Why is the Font property ignored?
It isn't. My controls have a property UseSystemFont which defaults to True. This property tells the control to use the system font rather than the font set by the Font property.
Why is this property's default True? Well, if I set system wide settings (like fonts) I expect all applications to follow them. Unfortunately ignoring system wide settings seems to be trendy, so see my decision as an educational measure.

2. Why is event xyz not fired?
Firing an event is relative time-consuming, even if the event isn't handled by the application at all. Therefore I implemented a DisabledEvents property which can be used to deactivate certain events.
By default many events are deactivated.

3. What is the maximum length of the text that the TextBox control can handle?
The magical value is 65535. This is the maximum number of characters that the TextBox control can handle without problems. The control can display longer texts, but some features (e. g. drag'n'drop) won't work correctly then. This is due to limitations of the native Edit control.
