Creating a List View Control

To create a list view control, use the CreateWindowEx function, specifying the WC_LISTVIEW window class. The list view window class is registered in the application's address space when the common controls dynamic-link library (DLL) is loaded. To ensure that the DLL is loaded, call the InitCommonControls function before creating the control.

When you call CreateWindowEx, you can specify a combination of list view window styles to control the appearance and attributes of the control. For a complete list of the list view window styles, see List View Window Styles.

The following example creates a list view control and then calls application-defined functions that add image lists, columns, and list view items. The window style specifies the list view control's initial view and other options. This example specifies report view, which enables the user to edit the labels of list view items.

// CreateListView - creates a list view control.

// Returns the handle of the new control if successful or NULL

// otherwise.

// hwndParent - handle of the control's parent window

// pfData - file containing list view items

HWND WINAPI CreateListView(HWND hwndParent, FILE *pfData)

{

HWND hwndLV;

// Force the common controls DLL to be loaded.

InitCommonControls();

// Create the list view window.

hwndLV = CreateWindow(WC_LISTVIEW, "",

WS_CHILD | LVS_REPORT | LVS_EDITLABELS,

0, 0, CW_USEDEFAULT, CW_USEDEFAULT,

hwndParent, NULL, g_hinst, NULL);

if (hwndLV == NULL)

return NULL;

// Call application-defined functions to initialize the

// image lists, add columns, and add some items.

if (!InitListViewImageLists(hwndLV) ||

!InitListViewColumns(hwndLV) ||

!InitListViewItems(hwndLV, pfData)) {

DestroyWindow(hwndLV);

return FALSE;

}

return hwndLV; // return the control's handle

}

    Nostalgia .Net     .Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More »
