Changing places on items in treeview!

Lars Grøtteland

Hello!

During drag&drop of items in a CTreeView - how do I replace items on the
tree which I drag an item on top of.

We can use the example of WindowsXP. In the start menu -> Programs ->
Startup. I can change places on items in that folder. How can I do that in
the treeview? Anyone know?

Use TreeView_Select Item for the drop source and TreeView_Select DropTarget
for the drop target. You may also want the "track select" style turned on
and use TreeView_Create DragImage for the source item.

Use TreeView_GetIte m, then TreeView_Delete Item and TreeView_Insert Item to
move it. (Using TreeView_GetIte m with all the flags set should get you as
much information as you need to re-insert the item without losing
information.)

This still won't quite be like the menus (it will select an item rather than
show an insertion point between items) but it's probably as near as you are
going to get with a tree.

See "CTreeCtrl, drag and drop operations" in MSDN for more information.

Remove items form ListView and Treeview

by: Progalex | last post by:

Hi everybody! I have a listview and a treeview in a form . With an OpenDialog I let the user select multiple files and then these files are added to the listview with the complete pathname, while they are added to the treeview without the path (only file name). I'd like the user would be able to remove multiple items selecting filenames from the listview. So, items should be removed both from the listview and the treeview. How can I do...

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
