If you're using OCX version 6 then you have a forecolor property:

* here is the call to set the node's forecolor ..
setNodeEnableColor(oTV.Nodes(cTheSelectedNodeKey),.f.)

PROCEDURE setNodeEnableColor(oNode,llEnabled)
oNode.forecolor=IIF(llEnabled,RGB(255,0,0),RGB(0,0,255))
ENDPROC &&setNodeEnableColor(oNode,llEnabled) 

* Then at top of your node click
PROCEDURE  NodeClick(node)
IF node.forecolor=RGB(0,0,255) && Disabled
   node.selected=.f.
   * do disabled node house keeping here
ELSE && it's enabled
   node.selected=.t.
   * do enabled node processing here
ENDIF &&node.forecolor=RGB(0,0,255) && Disabled
ENDPROC &&NodeClick(node)

We don't have forecolor in OCX version 5.
If you are attempting to prohibit a process when a "cluster" node is selected (as opposed to a "leaf" node), then you could simply reset the state. In this presentation (download #16575) there is a demonstration on applying different house keeping rules based on cluster or leaf selection.
