Hello...
What I would like to do is similar to FolderBrowserDialog1 with the same behavior.
I found this code, which allows to build, folder browser, but I can't get the folder path when selecting the desired item.

Often people have a fundamental problem to solve and they think they have a solution to the fundamental problem but then they need help with that solution. Every time I have seen that the person has chosen the wrong solution. In this case, you are trying to get the files in a directory (or something like that) and put them in a tree control and you are trying to do it the hard, very low-level way. You need to describe (1) what you need to do and ask (2) how to do it using managed classes.
Hello
The code creates a TreeView with the INameSpaceTreeControl interface.
Example
Now what I want is, when I select the node / item from the created TreeView, it shows me the folder path in a MessageBox.Show as a result.
Thank you
I had posted a method in this thread : Populating a listbox with files / folders from a root folder path
with WM_NOTIFY (not the best way as I wrote...) to get the current selected item
I get the name in the sbItemName variable
Great, but, I would like to adapt it, that when I press a Button1 it shows me its folder path in MessageBox.Show.
is there any way to do that?
Also, is there a way to create a new folder in the TreeView created by pressing Button2?
example
If possible could you help me with an example please.
> Great, but, I would like to adapt it, that when I press a Button1 it shows me its folder path in MessageBox.Show.

I don't see the problem : just display the variable sbItemName (by making it global or with another global variable), which contains the current selected folder, in a MessageBox
But why do you want to reprogram all the FolderBrowserDialog ? (it is re-inventing the wheel...)
Thank you.
I tried to customize the FolderBrowserDialog control, which would do the copy operation in a project that I am doing, but it seemed very difficult, so I decided to make my own FolderBrowserDialog for my purpose.
Maybe you could customize SHBrowseForFolder, like in this article FolderBrowserDialogEx: A C# Customization of FolderBrowserDialog
but it depends on what you want to add to the standard DialogBox.
Thank you.
