Hi Mark, 
I have a sample.py file like this 

imports ....
imports....


Class Test TreeView(UnitTest.testcases) :

 def setUp(self) 
      app= Application()
       app.connect_( ...... ) I connect to application here, that is already opened.

     # get the dialog and ensure it is correct...
     my_dialog = app.window_(class_re = "...")  # there is probably nothing to do with tree view on this line
     my_dialog.DrawOutline("red")  # you should see a red outline around the dialog
 
     # try to get the treeview window...
     my_tree = my_dialog.TTreeView1
     my_tree.DrawOutline("green")    # should see a green outline around the tree view
 
     print my_tree.__class__.__name__  # is maybe printing windowspecification
 
     # force to TreeViewWrapper
     from pywinauto.controls.common_controls import TreeViewWrapper
     my_tree = TreeViewWrapper(my_tree.handle)
 
     print my_tree.__class__.__name__  # IS PRINTING  TreeVIewWrapper
 
        my_tree.Select((0,1))  # 


 def testSelect(self) 
     "Selecting the testcases"

if __name__ == "__main__"
unittest.main()

When I execute this in command prompt using " python samlpe.py "he clicks on TreeNode with no errors.




But when I have the code( with out class and func def) in a separate file called TriewView.py like this 

#  I have the necesay imports here ....
imports ....
imports....

 app= Application()
  app.connect_( ...... ) I connect to application here, that is already opened.

# get the dialog and ensure it is correct...
my_dialog = app.window_(class_re = "...")  # there is probably nothing to do with tree view on this line
my_dialog.DrawOutline("red")  # you should see a red outline around the dialog
 
# try to get the treeview window...
my_tree = my_dialog.TTreeView1
my_tree.DrawOutline("green")    # should see a green outline around the tree view
 
print my_tree.__class__.__name__  # is maybe printing windowspecification
 
# force to TreeViewWrapper
from pywinauto.controls.common_controls import TreeViewWrapper
my_tree = TreeViewWrapper(my_tree.handle)
 
print my_tree.__class__.__name__  # *******************IS PRINTING DIALOGWrapper INstead of TreeViewWrapper**********
my_tree.Select((0,1))  # 



When I try to execute this from cmd prompt it throws an attribute error

Attribute Error:  DialogWrapper object does not have attribute select.

The difference between the two is I have a Class and two functions inside that , I have the code 
in first approach, in the second one i dont have any class definition; 

The mode of execution like shown in second approach is very important for me since I am trying to 
parameterize the execution of python from Boost C++ Library

Could You please tell me where the mistake is ? 

with regards,
Raghav
