Introduction

ComboListBoxControls is a collection of combo and list box ActiveX controls. The ComboBox control wraps the ComboBox window class, the DriveComboBox and ImageComboBox controls wrap the ComboBoxEx32 window class and the ListBox control wraps the ListBox window class.
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: ComboBox, ComboBoxEx32 and ListBox. Although I tried to wrap all features of these window classes (status: Windows 2008 R2), 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

ComboListBoxControls 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
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

Although there's no entitlement to support, you've good chances to get help if you either post to the forums or send me a mail.
Bugs and feature requests should be entered into the bug tracking system.

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.
