Note There is a bug in the original release of this sample which prevents the LISTVIEW.SCX form from running in Visual FoxPro 7 - 9. When you run the form in those versions of VFP, you will receive the following error message in the BuildSelectedItemText() method of the form:
Error 107
Operator/operand type mismatch
The bug can be fixed by changing this line in that method:
" ReportIcon: " + loListSubItem.ReportIcon + CRLF + ;
to this:
" ReportIcon: " + IIF(ISNULL(loListSubItem.ReportIcon), "", loListSubItem.ReportIcon) + CRLF + ;
When you save and recompile the form, you may also receive an error message about a missing INCLUDE file. You may receive this message because the form was hard-code to include FOXPRO.H from the VFP6 default installation directory.
To resolve this problem, point the form designer
Include File dialog to
FOXPRO.H in the
HOME() directory of your current VFP version when you are prompted.

The
ListView control is an ActiveX control that provides a visual interface to
display items in table form or in lists with an associated icon. Windows
Explorer is an example of an application that uses a
ListView control.
The
ListView control uses two collections of objects,
ListItems and
ColumnHeaders, to store and display data. The
ListItems collection contains
ListItem objects. Each
ListItem represents an individual item that can be displayed in the
control. Each
ColumnHeader represents a column of
ListItem objects.
A
ListItem has a label represented by the
Text property and an icon represented by the
Icon or
SmallIcon properties. Additionally, a
ListItem has a
Selected property to indicate if a user selects the item. It also has a
ListSubItems collection that you can use to add other information to the
control.
This example contains a project (
ListView) that contains one form (
ListView), two tables, each with an index (.cdx) and a collection of
bitmap (.bmp) and icon (.ico) files. The
ListView form contains a
ListView control and other controls that allow you to manipulate or view
the properties of the
ListView and also the currently selected list item in the
ListView. There are Tooltips that help explain the purpose of the property
that is being controlled or displayed. There are also three
ImageList controls on the form. Both oleImageList1 and oleImageList2
contain icons for the
ListView control to use. The icons for the "large icon" view are stored in
oleImageList1. The icons for the "small icon" and "list" views are stored in
oleImageList2. Both of these image lists are loaded with images through code in
the form's
Init event. Icons used on the Column Headings in the "detail/report"
view are stored in oleImageList3. The images for oleImageList3 are loaded
during design time.
When the form is executed, it loads information
from the Customer table. It uses the Countrys table to find the name of the
Icon file to use for that country. If a country cannot be found, it uses the
default icon (Question.ico) and the
Ghosted property of that
ListItem is set to
True. If the country is USA, the
Bold properties of the
ListItem and the
ListSubItems are set to
True and the
ForeColor properties are set to
Blue.
The default view of the
ListView is the "large icon" view with the icons listed in company name
order in ascending sequence. When the
ListView is in "detail/report" view, you can click the column headings to
set the sort order and sequence. The first click on a column heading sets it in
ascending sequence; the second click sets it in descending sequence.
The
ListView control does have a
Picture property so you can set a wallpaper behind the
ListItems. The Santa Fe Stucco bitmap file has been included so that you
may try this feature out.
