Windows UI Automation not showing all child elements?

Question

I have a TreeView control on my form, and I\'m recursively going through the elements of another window starting with the window itself. I\'m using this to find the element

Answer 1

Could you give a better example of what fails? Thinking about the problem, it may be that the 'element' in the other form is being drawn manually, and so doesn't have distinct registered handles for everything.
