CListBox::SetItemHeight 

Sets the height of items in a list box.


int SetItemHeight(
   int nIndex,
   UINT cyItemHeight 
);

Parameters

nIndex

Specifies the zero-based index of the item in the list box. This parameter is used only if the list box has the LBS_OWNERDRAWVARIABLE style; otherwise, it should be set to 0.

cyItemHeight

Specifies the height, in pixels, of the item.

LB_ERR if the index or height is invalid.

If the list box has the LBS_OWNERDRAWVARIABLE style, this function sets the height of the item specified by nIndex. Otherwise, this function sets the height of all items in the list box.

// The pointer to my list box.
extern CListBox* pmyListBox;

// Set the height of every item to be the
// vertical size of the item's text extent.
CString str;
CSize   sz;
int     dx=0;
CDC*    pDC = pmyListBox->GetDC();
for (int i=0;i < pmyListBox->GetCount();i++)
{
   pmyListBox->GetText( i, str );
   sz = pDC->GetTextExtent(str);

   pmyListBox->SetItemHeight( i, sz.cy );
}
pmyListBox->ReleaseDC(pDC);
