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.exe file contains the following files:

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.
