TimoSoft ExplorerListView 188.8.131.524
ExplorerListView is an ActiveX control that may be used as a common listview as well as for shell-browsing. It is optimized for Visual Basic 6.0, but should also work in any other environment that supports COM controls.
The control superclasses the listview listview window class of Windows:
SysListView32. Although I tried to wrap all features of this window class (status: Windows 10), some things may be missing. In these cases you usually may use the Win32 API and handle the control as a native listview window. One of my goals was it to create a listview control that may be controlled via API as well as via the classes that I implemented.
The control's contained edit and header controls are native edit respectively
SysHeader32 windows of Microsoft Windows and may be controlled via API, too.
By "contained edit control" I mean the label-edit control as well as the filter-edit control.
ExplorerListView Unicode runs on the following operating systems:
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.
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.

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
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. Why can't I compare
ListViewItem objects using VB's
Is operator compares the objects by there memory address. To keep memory usage low and to ease internal item management, ExplorerListView creates objects, that wrap items or item collections, on the fly. Therefore you'll get different objects (with different addresses) for the same item. Because of the different addresses the
Is operator handles the items as different ones.
To compare items, you should use the items' indexes or IDs.
4. The control doesn't seem to have full Unicode support if it is used in Visual Basic 6. Why?
The forms, that Visual Basic 6 is creating, are ANSI windows. Therefore they force the control's underlying native listview window class to use ANSI messages when communicating with the form. This breaks Unicode support in some situations. To work around this problem, the
WM_NOTIFYFORMAT message must be reflected back to the control.
In Visual Basic, you must subclass the control's container window and send
WM_NOTIFYFORMAT back to the window that it was sent for. In C++, message reflection works similar. The sample projects teach you how to reflect the message.
