<div class="symptoms_section">

SYMPTOMS
CListCtrl member functions GetItem and SetItem lack an Indent parameter.

<div class="cause_section">

CAUSE
The LVITEM structure was modified with version 4.70 of ComCtrl32.dll to include an indent parameter. This parameter specifies how many image widths to indent an item. However, there is no place to specify this parameter in the form of the CListCtrl member function SetItem that takes a list view item's attributes.

<div class="resolution_section">

RESOLUTION
You can set the value of the iIndent member of the LVITEM structure by using the form of the CListCtrl member function SetItem that accepts a pointer to a LV_ITEM structure. For example: void CMyCListCtrl::SetItemIndent( int nItem, int nIndent ) {     LV_ITEM lvi;

lvi.iItem = nItem; lvi.iSubItem = 0; lvi.mask = LVIF_INDENT; lvi.iIndent = nIndent;

VERIFY( SetItem( &lvi ) ); } Likewise, to obtain the indentation of an item in a CListCtrl, use the form of the CListCtrl member function GetItem that accepts a pointer to a LV_ITEM structure: int CMyCListCtrl::GetItemIndent( int nItem ) {     LV_ITEM lvi;

lvi.iItem = nItem; lvi.iSubItem = 0; lvi.mask = LVIF_INDENT;

VERIFY( GetItem( &lvi ) );

return lvi.iIndent; } Note that because iIndent specifies the number of image widths to indent the item, you must associate an image list of small images with the items.

<div class="status_section">

STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

<div class="moreinformation_section">

MORE INFORMATION
CListCtrl::SetItem has two forms: one that takes a pointer to an LV_ITEM structure and one that takes individual parameters. The second form does not have a parameter representing the number of image widths to indent an item.

Additional query words: LVITEM LV_ITEM LVM_SETITEM LVM_GETITEM CListView
