Are you sure that your listcontrol has a valid handel when you are callin=

your method?
Yes after reading these comments I added the following lines to test
if the ListCtrl does have a valid handle. It seems to have one. Thanks
for the reply.
if(!ref_listCtrl)
return FALSE;
BOOL CMyListView::GetSysImgList()
{
SHFILEINFO shFinfo;
HIMAGELIST hImgList = NULL;
CListCtrl& m_listCtrl = GetListCtrl( );
m_ is generally only used for member variables, it is confusing when you
give m_ names to stack variables.
I learn fairly quickly and I am certain that I won't make the same
mistake. Thanks for the reply.
if ( m_listCtrl.GetImageList( TVSIL_NORMAL ) )
m_imgList.Detach();
why are you detaching whats in your m_imgList? Should you destroy it i=
f you
don't want to use it anymore?
The reason that I am detaching the image list is so that I can ensure
that the image list contains only the built in system list and not any
other list that may have been used somewhere in the code elsewhere. If
you mean "detach" of this list then I believe that I have in the
destructor of my derieved ListView class. Thanks for the reply.
hImgList = (HIMAGELIST)SHGetFileInfo( _T("C:\\"), 0, &shFinfo, si=
zeof
( SHFILEINFO ), SHGFI_SYSICONINDEX | SHGFI_SMALLICON);
if ( !hImgList )
{
m_strError = "Cannot retrieve the Handle of SystemImageLis=
t!";
return FALSE;
}
if ( !m_imgList.Attach( hImgList ) )
{
m_strError = "Cannot Attach SystemImageList-Handle";
return FALSE;
}
m_listCtrl.SetImageList( &m_imgList, LVSIL_SMALL );
return TRUE; // OK
}
