>I have tried your coding but I still get the error msg 'ole IDispatch exception code 0 from Nodes:element not found' and I click on the ignore button. The tree only list out the Name that i keyed, it childs not listed out.

I think that the error maybe being caused because you where trying to add a child of a node that was not there. If you have the debugger up while running the code you can check for this. Make sure that the table is ordered to ensure that a parent is created before you try to create any of its children.
