How to handle Windows authentication dialogue using selenium webdriver? - selenium-webdriver

I have requirement of opening share point URL and it looks for credential through windows authentication. So I read some where to use AutoIt with seleniun webdriver but how we can call this AutoIt script because my web driver script will wait until window dialogue is get off. So cursor will not go to next line to execute AutoIT script and finally we will not be able run our script.

Not sure if you are using Java or C#. In C#, I would go with MSUIA. Write a method to deal with the Windows dialogues and run it on a separate thread. This method should act as a listener to the Desktop tree and whenever encounters a control that it needs to work on, does its job. Have the method scan the Desktop tree once every 5 seconds or so and put it to sleep if no object is found.
In Java, using AutoIt should do the trick, not that it won't in C#

How to make WebDriver operate browser in background?

I have a python script which uses Selenium WebDriver to start a Chrome, open an URL, enter simple captcha, check if some data available (time for visit government organization) and repeat this process in 5 minutes.
I want it work in background. Headless mode is not an option because site would show DDos Guard in that case.
I have tried to use driver.minimize_window() but the windows activates for short periods for number input and click of button which is annoying when I work on PC.
Is it possible to make it work completely in background without activate Chrome window?
You can packaging your script using PyInstaller, then run it with Windows Task Scheduler (assuming you are using Windows)
Install pyinstaller
pip install -U pyinstaller
2. Packaging your script (run in cmd)
pyinstaller --onefile --name=your-package-name yourscript.py
Check pyinstaller docs and make sure add --hidden-import or --collect-data flag if needed.
Setup your task scheduler:
Create basic task, choose task name, and description (if needed)
Create trigger
Set action to start a program then define your script name in Program/script and make sure put your script folder path in Start in
Then voila. You can custom the trigger more detail in task properties (creating multiple triggers, specific conditions, etc...)
You could try to start your exe file as process manually using cmd/powershell like this SO answer, and some kind of process/service manager but I have never tried it yet.
When I use selenium and headless option don't work with me, I always do this trick by changing the window size and just leave it.
So, set the window size in the driver itself, like this:
driver.set_window_size(1, 1)
Or, set it as an argument, like this:
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument('window-size=1,1')
Or use both.
I hope this helps you.

Running a VBscript with system account

I have a VBScript which basically calls some Informatica CLI commands. These commands will take a long time to execute and the script runs in a Windows 2003 server.
cscript //B //Nologo <script> params...
Actually, I am calling this script from a .NET Winforms application. The idea is, even when form is closed, the script continues to run. It works fine, as long as user is logged on, i.e. even when winform is closed, the script runs as a (user) process and execute the command.
The problem is however when the user logs off (or) remote system (MSTSC) times out, the (cscript) process is killed.
Is there anyway this can be run as a system process so that even when user logs off, the script continues to run?
(Please note that running the .NET EXE as a Windows service is a last option, which is currently not viable..)
Only way I know to do this is a pretty dirty hack so you should at least consider the .NET service approach... Visual Studio offers great tools which allow you to make a Windows service very easily.
What you can do if that is really not an option is using the task scheduler. As long as you do not need user interactivity you can say a task should be "Run whether a user is logged on or not". If you do this you are allowed to use "SYSTEM" as the account to run the task with. So you can create your task executing your script without any trigger, and then manually trigger the task from the program.
There is no nice way to do this from C# but you can just execute schtasks /run /tn <taskname> or do a quick google search for some of the wrappers people wrote for this. The script will run (invisibly) in the background and survive user logoff if started that way.

Start Play Application and Close Window

I have a play application on a Windows 7 machine which I want to start via double click on a batch file.
This batch file starts a service. Calls the play application to run in production mode, waits for 5 seconds and open a browser with a specified url.
Therefore I used the following script:
call net start service1
CALL "D:\play-1.2.5\play.bat" start --%%%%prod -Dprecompiled=true
TIMEOUT /T 4
call "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" localhost:9000
exit
Now when I start the batch file the window opens and all commands are executed. Sadly Play is still writing his output to cmd and the window is not disappearing. If I close the window manually play is stop executing.
If I run play with "play start" from cmd, play is starting in the background and everything is fine. Play still runs even if I close the window.
I want to have exactly this behaviour when I start the application with my batch file.
Thanks
If you were using a linux-like environment, I' d recommend you to use 'nohup' command and a '&' sign in the end. However, as far as I know there is no direct equivalent of beautiful 'nohup' command on Windows, unfortunately. So, what I can think of is, you can create a tiny win api application that utilizes CreateProcess command and give it the required parameter to hide command line window as soon as the process is created. There are also other process creation functions such as WinExec that you can use to hide command line.
I don't know what Play is so I can only take a guess :) but try using the batch without the call's as I don't think they are necessary, and you never know, might fix the issue.
1) You see Play's output because ot redirect only system.out but write system.err to the same console.
2) I also have this problem and looking for a solution. As a workaround you could try to use some Java Wrapper and install your Play! application as a Windows Service.
3) Play! app could be started via Ant task. I haven't tried this yet.

Running console app with parameters from NSIS installer

I am creating one installer for my project. Deployment of project needs some changes that are too complex with NSIS.
So for making it easy I have written one console app in C#. This app will do all the complex changes required with use of some parameters.
I just want to ask what is the way to call this console app with some parameters from my installer?
Is it possible by creating some batch file or what?
ExecWait '"$instdir\myapp.exe" /foo "hello world" /bar' is the basic method.
Use nsExec if you want to hide the console window and ExecDos or ExecCmd if you need more control...
You have several options to execute programs from NSIS, as documented here: http://nsis.sourceforge.net/Docs/Chapter4.html#4.9.1.2
Exec : Execute the specified program and continue immediately
ExecShell: Execute the specified program using ShellExecute
ExecWait: Execute the specified program and wait for the executed process to quit
the last solution is probably what you need.

How do I launch a WPF app from command.com. I'm getting a FontCache error

I know this is not ideal, but my constraint is that I have a legacy application written in Clipper.
I want to launch a new, WinForms/WPF application from inside the application (to ease transition). This legacy application written in Clipper launches using:
SwpRunCmd("C:\MyApp\MyBat.bat",0)
The batch file contains something like this command:
C:\PROGRA~1\INTERN~1\iexplore "http://QASVR/MyApp/AppWin/MyCompany.MyApp.AppWin.application#MyCompany.MyApp.AppWin.application"
It is launching a WinForms/WPF app that is we deploy via ClickOnce. Everything has been going well until we introduced WPF into the application. We were able to easily launch from the legacy application.
Since we have introduced WPF, however, we have the following behavior. If we launch via the Clipper application first, we get an exception when launching the application. The error text is:
The type initializer for 'System.Windows.FrameworkElement' threw an exception.
at System.Windows.FrameworkElement..ctor()
at System.Windows.Controls.Panel..ctor()
at System.Windows.Controls.DockPanel..ctor()
at System.Windows.Forms.Integration.AvalonAdapter..ctor(ElementHost hostControl)
at System.Windows.Forms.Integration.ElementHost..ctor()
at MyCompany.MyApp.AppWin.Main.InitializeComponent()
at MyCompany.MyApp.AppWin.Main..ctor(String[] args)
at MyCompany.MyApp.AppWin.Program.Main(String[] args)
The type initializer for 'System.Windows.Documents.TextElement' threw an exception.
at System.Windows.FrameworkElement..cctor()
The type initializer for 'System.Windows.Media.FontFamily' threw an exception.
at System.Windows.Media.FontFamily..ctor(String familyName)
at System.Windows.SystemFonts.get_MessageFontFamily()
at System.Windows.Documents.TextElement..cctor()
The type initializer for 'MS.Internal.FontCache.Util' threw an exception.
at MS.Internal.FontCache.Util.get_WindowsFontsUriObject()
at System.Windows.Media.FontFamily.PreCreateDefaultFamilyCollection()
at System.Windows.Media.FontFamily..cctor()
Invalid URI: The format of the URI could not be determined.
at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)
at System.Uri..ctor(String uriString, UriKind uriKind)
at MS.Internal.FontCache.Util..cctor()
If we launch the application via the URL (in IE) or via the icon on the desktop first, we do not get the exception and application launches as expected.
The neat thing is that whatever we launch with first determines whether the app will launch at all. So, if we launch with legacy first, it breaks right away and we can't get the app to run even if we launch with the otherwise successful URL or icon. To get it to work, we have to logout and log back in and start it from the URL or icon.
If we first use the URL or the icon, we have no problem launching from the legacy application from that point forward (until we logout and come back in).
One other piece of information is that we are able to simulate the problem in the following fashion. If we enter a command prompt using "cmd.exe" and execute a statement to launch from a URL, we are successful. If, however, we enter a command prompt using "command.com" and we execute that same statement, we experience the breaking behavior.
We assume it is because the legacy application in Clipper uses the equivalent of command.com to create the shell to spawn the other app. We have tried a bunch of hacks like having command.com run cmd.exe or psexec and then executing, but nothing seems to work.
We have some ideas for workarounds (like making the app launch on startup so we force the successful launch from a URL, making all subsequent launches successful), but they all are sub-optimal even though we have a great deal of control over our workstations.
To reduce the chance that this is related to permissions, we have given the launching account administrative rights (as well as non-administrative rights in case that made a difference).
Any ideas would be greatly-appreciate. Like I said, we have some work arounds, but I would love to avoid them.
Thanks!
It sounds like the Presentation Font Cache service has trouble starting when the app is launched in this way.
If you have control over the client environment, you could try setting the Windows Presentation Font Cache startup to automatic instead of manual.
This is a shot in the dark made with incomplete information:
command.com and cmd.exe are quite different. AFAIK, command.com exists for legacy compatibility, so applications you run from it will run differently. I can't test anything to complete my post because I believe that command.com runs in 16-bit mode and 64bit versions of Windows (on which I'm running) don't support that mode anymore so no more command.com for me.
That being said, there should be no difference when trying to run 32-bit applications (including managed applications).
I'm not aware of what are the limitations of your environment, but some things you may try are:
Rename you .bat into .cmd to make sure it starts with cmd.exe rather than command.com
Make your .bat start the program using the start console command
Have a non-WPF program to invoke your WPF one with a more sane environment
The problem is that the windir environmental variable is not set when using command.com.
So, in your case, adding the line set windir=C:\Windows to the beginning of the bat file will solve the problem (assuming that you have your Windows instalation in C:\Windows.
An additional issue might be that the host application is running command.com in compatibility mode. The best is to list all the environmental variables after running cmd.exe (using the set command) and comparing it to the output of the set command that you set in your bat file
