How to create a multicolumn Listbox?

Question

Hi!

I'm working on a program, which should list all files and it's size(for now...). I created a simple application, which should write the data to a listbox. I'm trying to write the data in two columns(the first should be the name, and next to it, in an other column, it's size), but i can't figure out, how should i do this. Can someone help me?

Thanks in advance!

Update:

I try to use ListControl., but unfortunately i can't. I can succesfully compile my App, but i can only see, the empty rectangle. Does someone know what i am doing wrong?

BOOL CGetFileListDlg::OnInitDialog()
{  
CDialog::OnInitDialog();

// Set the icon for this dialog.  The framework does this automatically
//  when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE);         // Set big icon
SetIcon(m_hIcon, FALSE);        // Set small icon

// TODO: Add extra initialization here

LVITEM lvItem;
LVCOLUMN lvColumn;
int nCol;

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;
lvColumn.fmt = LVCFMT_CENTER;
lvColumn.cx = 10;
lvColumn.pszText = _T("Filename");
ListView_InsertColumn( m_List, 0, &lvColumn ); 
ListView_SetItemText( m_List, 0, 0, _T("TEST") );

return TRUE;  // return TRUE  unless you set the focus to a control    
}

Answer 1

Don't use a List Box, use a List Control with LVS_REPORT style.

Answer 2

Maybe to use DataGridView with object as data source.

Answer 3

The list box control does support multiple columns, but it only supports a single series of entries; the multiple column support just makes the items continue onto the next columns so that vertical scrolling is not necessary.

As Kornel has suggested, a list view control may be more appropriate. After creating a list view control, use ListView_InsertColumn to create the columns. Then use ListView_SetItemText to insert items.

EDIT: My apoligies; you should use ListView_InsertItem to insert an item (a row) and then use ListView_SetItemText to alter the subitems (columns). If the list view is still just a blank box without any headings, have you initialised common controls? This can be done using InitCommonControlsEx, specifying the ICC_LISTVIEW_CLASSES constant. This should be done before creating the control.

See Microsoft's documentation on list view controls.
