Limit CListCtrl to one column when in LVS_SMALLICON mode

I have CListCtrl that displays text and small icons while in LVS_SMALLICON mode. Occasionally a short text string will result in two list items being displayed on the same row:
Image of CListCtrl with two items on one rowI tried using CListCtrl::SetColumnWidth(), but it doesn't work when in LVS_SMALLICON mode. I tried using LVS_LIST mode and SetColumnWidth() which does fix this problem, but it then only has a horizontal scrollbar and puts information that doesn't fit in the list to the right (whereas I need one long column and a vertical scrollbar).

Thanks.

You could consider using a ListBox (not ListCtrl) instead - that only has one column.  (Except if you instruct it to use multi column that is).

THanks Andy, but list boxes don't support icons (I'd need to do an owner draw which requires signifiantly more code).

Yeah, but I don't think what you want is possible - at least not without a lot of code either.

you could use report style (LVS_REPORT) and have 1 column.

I didn't save the code where I was having this problem, but after a lot of trial-and-error, I now have it displaying in one column. Sara's suggestion was good, because the LVS_REPORT style does allow you to control the number of columns, but we chose to stay with the LVS_SMALLICON style to be consistent with other lists in our app.

COurListCtrl::COurListCtrl(CWnd* pParentWnd)
{
	// Create the CListCtrl
	VERIFY( Create(LVS_AUTOARRANGE | LVS_ALIGNTOP | LVS_SMALLICON | LVS_SINGLESEL | WS_BORDER | WS_CHILD , CRect(0,0,120,300), pParentWnd, ID_OURID_LISTCONTROL ) );

	// Create a list of small icon images.
	VERIFY( (m_pImageList = new CImageList) != NULL);
	VERIFY( m_pImageList->Create(16, 16, ILC_COLOR16, 0, 1) );

	// Attach the image list to the list control.
	VERIFY( SetImageList( m_pImageList, LVSIL_SMALL ) == NULL);
}

See the explantion for why this, and Sara's, solutions both work. My solution was easier to implement, because our code was already based on a small icon list.
