selection in CTreeCtrl
I have a Tree Control in my application that displays two types of items:
type A and type B.
I want to implement the following:
1. When user clicks on any item of type A it should be shown as selected and
the previously selected item will be deselected - it is actually the default
2. When user clicks on any item of type B - nothing should happen: the
previously selected item remain selected and the clicked item remains
deselected. So, actually, I want that the items of type B will never
highlighted with a blue band.
How can do it?
Please ...Removing Item Highlight from CListCtrl
Hi I use MFC VC++ 4.2.
I have a CListCtrl, a few CEdit, a Clear Button and a few buttons.
Clear button function is to clear all CEdit and also clear the highlight
from the selected item.
My question is:
1. How to remove the highlight from the selected item?
2. I also need to disable a few buttons if there is no item selected.
How to do those things?
Thank you very much.

I am using CListCtrl within CListView. The first column of the list

...non-XP CListCtrl with groups
I like the grouping feature in MFC's CListCtrl, but it only works for XP.
Has anybody seen any code that implements this feature for previous OS's? I
searched around for quite a while and came up empty.
I'm looking to do it for an icon view. So, I'd have labeled groups of
thumbnails in a scrollable window.
...? Images in Subitems but Not Column 0 of CListCtrl
I've put an image in column 1 of a list control, but using SetImageList to
activate images also puts one in column 0.
I've tried setting the item's image to I_IMAGENONE aka -2, (which is only
available with _WIN32_IE >= 0x0501), but while that prevents the icon from
showing, it leaves a blank space the width of the icon next to the label-which
is particularly annoying since I've used SetColumnOrderArray to put column 1
with the image to the left of column 0.
Is there a way to disable images for column 0?
On Tue,...CTreeCtrl ::EnsureVisible
I've been using a tree ctrl in a modeless dialog to display some data.
When I call ensurevisible(treeitemhandle) from outside the dialog it
works really well except if the handle is for a child item...
If the handle is for a child item then the scroll only goes to the
root node leaving the child hidden below the node.
this behavior still happens with the node expanded or collapsed before
No difference if I use SelectSetFirstVisible(treeitemhandle) still
only scrolls to the node.
Any ideas what might be happening or someway to make it work right?

When I do a HitTest() from within OnDragOver() there are several things
that make no sense.
1) When I drag a file over the column headers in LVS_REPORT style,
HitTest() reports real list items that are hidden under the header bar,
rather than -1. When the list is scrolled to the top, it reports Item 0
as being under the header making its hit area twice as big as other

I have a CTreeCtrl and a 3D render view.
With the mouse, I create elements picking in the 3D render view. This
elements must be showed in the CTreeCtrl.
What is the process to do it?
I think 3D render view must send a message to the CTreeCtrl. CTreeCtrl
captures it and update itself.
But what kind of message and how?

I've encountered a situation where calling SortChildren (or SortChildrenCB)
centers the scrollbar of my CTreeView pane for the selected item (even if
the scrollbar was all the way to the left)
I can't find anything in the knowledge base on microsofts site about this at
Anyone have any ideas?
If I was to guess at what you are trying to say, seems like that your
Horizontal Scrollbar gets centered when you sort your treectrl. That's
because the selected item at the time of SortChildren call is larger than
the width of the window.
