Bug fixes and minor enhancements to the control:

The Selected property of a ListItem always returned false, meaning it was impossible to determine which items were selected in a multi-select ListView. Corrected. Same problem with the ItemCut property.

Icon property of ListItem set the icon of the next item along in the control. Fixed.

Position property added to the ColumnHeader object to allow the order of the column headers to be read and set programmatically.

Insert before parameter to the Add method of the ListItems collection was ignored. Corrected.

Setting a column alignment to right caused the column to be centred, and vice-versa. Fixed.

Mouse Up events were only generated for double-clicks. Now corrected.

A KeyDown event was generated when a KeyUp should have been. Fixed

Option to place the background image at a specified location rather than tile it added.

NoColumnHeaders property added to allow column headers to be hidden in Detail view.

Added a call to LoadLibrary on Shell32.DLL to prevent crashes when using a manifest.

Thanks to Ben Andersen, Ian Goodwin, Vasanth Raj, Greg Thomson, Frank Peters for the bug reports and code.

I'm currently trying out the above named control from the vbAccelerator site. Works very well and I commend you on what you have done. I have noticed a slight bug with the columns property - in that remove and clear do not appear to have any effect. I downloaded the source code and was somewhat baffled by the code, but I was able to work out most of it. I see that the clear function has a 'TODO' by it so that explains that. The remove function does not however and I stuck some simple test code in and still can not get columns to be removed. The SendMessage function is probably failing to remove the column (for whatever reason) and obviously it has no way of returning a failure. Has anybody else had this problem? I'm running XP Pro and VB6 SP3. Any suggestions would be very gratefully received.

In the cColumns class, it looks like the remove method was intended to allow removal by name in addition to index; the index (passed to the remove method as a variant) was never actually passed to the method in the control. (fRemoveColumn) - the newly dimensioned long lIdx was instead passed which means it always attempted to remove the zero'th column which the SendMessageLong never accomplished.
