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?

Ok here is the problem. I have created an owner drawn tree
(CCheckTree). Each node in the tree has a check box beside it. I have
derived (CEditableCheckTree) from (CCheckTree). CEditableCheckTree has
the edit labels style. When I call the EditLabel function the edit
control shows up but when I left click in the edit control the caret
isn't placed in the control, I can't select the text, or type into the
control. I can right click and paste into the control, but that is just
about all. Also if I call the edit control's SetFocus function it never
receives focus. I know that I'm o...CTreeCtrl

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?

I have a CTreeCtrl and a 3D render view.

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.
I think there is only one way...Vector CTreeCtrl

I created a simple dialog project to learn how to use images with a
CTreectrl object. Below is the code that I am using to load the images and to

of the one indexed. What am I missing? My image list is 15 pixels high and 90
pixels wide, containing 6 images.

I have a very strange problem.
I have a function that will fill a CTreeCtrl for me. In this function there
is a call to DeleteAllItems() before I start to add new stuff. When
DeleteAllItems() get's called, it causes the OnSelectionChange() event to
fire. This is where stuff get's weird.
In my OnSelectionChange() event, I get a void* to the selected Item's data,
then I pass that ptr to the properties controls to display info about the
selected item. No big deal. However, I have been getting trashed ptrs in
the OnSelectionChange() event and I can't really see why. One thin...Subclassing CTreeCtrl in CTreeView
