Hello Héctor.

>Hi, how can I make a pass for all the nodes in a treeview no matter the deep or how many they are.

The following code is untested and off the top of my head, but it should get you pointed in the right direction. If you have a form with a TreeView on it, just add this line of code to a command button that can kick off the process:

LOCAL loParentNode
loParentNode = Thisform.oTree.Nodes( 1 )
DO WHILE VARTYPE( loParentNode ) = [O]
  Thisform.ProcessNodes( loParentNode )
  loParentNode = loParentNode.Next
ENDDO

This code in ProcessNodes()

LPARAMETERS toNode
LOCAL loChildNode
? toNode.Text
IF toNode.Children > 0
  loChildNode = toNode.Child
  DO WHILE VARTYPE( loChildNode ) = [O]
    Thisform.ProcessNodes( loChildNode )
    loChildNode = loChildNode.Next
  ENDDO
ENDIF
