How can I programmatically check/uncheck nodes of a CheckBoxTree?

Resolved - assign nodes of the CheckBoxTree to its "SelectedNodes" property.

It is not the "SelectedNodes" property, but rather the "CheckedNodes" property to which you must add or remove nodes. What would be helpful is an example of how to do that.

I'm using app designer and came across this issue. The above answers gave me the idea to simply address them in the 'CheckedNodes' attribute of the tree.
The first entry is put into the 'CheckedNodes' list does not need to be indexed.
app.Tree.CheckedNodes = app.Tree.Children(i).Children(j)
The following code adds the 3rd child of the 5th parent entry (I know it says children twice), to the end of the entries in the 'CheckedNodes' attribute.
app.Tree.CheckedNodes(end+1) = app.Tree.Children(5).Children(3)
then checking the checked nodes:
app.Tree.CheckedNodes
The last entry is there!
You can also add all entries under a "parent" node as follows:
app.Tree.CheckedNodes(end+1) = app.Tree.Children(5).Children
Now to remove a specific entry, as far as I know, you would need to know where it is in the TreeNode array. I was able to uncheck a box by using the following code.
app.Tree.CheckedNodes(2) = '';
The entry was removed and box, unchecked!
Hope that helps!

string compare and everything that ai playground offers as an solution to find the place where the node is in the array doesn't work
