Automation Microsoft SQL Server 2008 R2 using Pyth

Question

I am creating Microsoft SQL Server Management Studio Automation tool using python. The problem is I can't select the Child_tree(Northwind) database It's selecting the Parent_tree(Databases). I need to do much more, clicking the child_tree(Northwind) right click option (Ex. Tasks-> backup). Help me to do the best automation code. Thanks in Advance.

import pywinauto
import socket
import binascii
host = socket.gethostname()   #Getting system host name
n2 = int('0b111000001100001011100110111001101110111011011110111001001100100', 2) #password
n1 = int('0b111010101110011011001010111001001101110011000010110110101100101', 2) # username
n  = int('0b1110011011001010111001001110110011001010111001001101110011000010110110101100101', 2) #servername av
if (host == "systemhostXXX" or host == "systemhostyyy"): # checking the host name 
     try:
        pwa_app = pywinauto.application.Application()
        path = pwa_app.start_(r"C:/Program Files (x86)/Microsoft SQL Server/100/Tools/Binn/VSShell/Common7/IDE/Ssms.exe") #Opening the .exe file

        print("Status: Application Launched successfully!!")
    except:
            print("Error: Applicatin Launching Error!!")
    try:


    pwa_app.ConnecttoServer.ComboBox1.Select("Database Engine")   #Selecting the combobox value 
    pwa_app.ConnecttoServer.edit1.SetText(binascii.unhexlify('%x' % n))
    pwa_app.ConnecttoServer.ComboBox3.Select("SQL Server Authentication")
    pwa_app.ConnecttoServer.edit2.SetText(binascii.unhexlify('%x' % n1))   # convert binary into string
    pwa_app.ConnecttoServer.edit3.SetText(binascii.unhexlify('%x' % n2))
    print("Status: Log-in Process!!")
    pwa_app.ConnecttoServer.Connect.Click()
except:
    print("Error: Log-In Failed!!Please Relaunch!")

try:
    pwa_app.ConnecttoServer.Ok.Click()  #Button click (OK)
    pwa_app.ConnecttoServer.Cancel.Click()
    print("Error: Restoration going-on!!")
except:
    print("Status: Log-in Success!!")

    try:
        w_handle = pywinauto.findwindows.find_windows(title=u'Microsoft SQL Server Management Studio', class_name='wndclass_desked_gsk')[0]
        window = pwa_app.window_(handle=w_handle)
        ctrl = window['TreeView']  
        ctrl.GetItem([u'SQL Server 8.0.2039']).Click() 
        ctrl.GetItem([u'SQL Server 8.0.2039', u'Databases', u'Northwind']).Click() #Selecting the database

    except:
        print("Database selection failed !!")

else: print 'Dear', host,'You are not Authorized to Run this program\n'

Answer 1

As I could understand in comments, you need waiting until main window is open after login.

window = pwa_app.Window_(title=u'Microsoft SQL Server Management Studio', class_name='wndclass_desked_gsk')
window.Wait('ready', timeout=20) # default timeout is 5 sec. if any
ctrl = window['TreeView']
ctrl.GetItem([u'SQL Server 8.0.2039']).Click() 
ctrl.GetItem([u'SQL Server 8.0.2039', u'Databases', u'Northwind']).Click() #Selecting the database

Please check how it works.

EDIT:

It seems you generated the code for 'Microsoft SQL Server Management Studio' window using SWAPY. It means that the window was already open.

But in automated workflow Log-in is quite long operation (may take up to 10 seconds I believe). So when you clicked "Connect" button, 'Microsoft SQL Server Management Studio' is not open yet. You may see some progress window or even nothing for a few seconds.

Function find_windows doesn't wait while the window appears on the screen. It just finds the window at that moment. So when you execute line

window = pwa_app.Window_(title=u'Microsoft SQL Server Management Studio', class_name='wndclass_desked_gsk')

WindowSpecification object is created (window variable). ctrl = window['TreeView'] is also WindowSpecification object. They are just descriptions and are not connected with real window/control. But the following statement

ctrl.GetItem([u'SQL Server 8.0.2039']).Click()

is equivalent to

ctrl.WrapperObject().GetItem([u'SQL Server 8.0.2039']).Click() 

or

ctrl.Wait('visible').GetItem([u'SQL Server 8.0.2039']).Click()

pywinauto hides WrapperObject() call using power of Python. So it's called automatically. Default timeout is 5 seconds in this case. It might be insufficient for long time operations like Log-in. That's why I suggest calling Wait('ready', timeout=20) explicitly. 'ready' means 'exists visible enabled' using logical AND.
