From C# console application I need to open the web browser and i want the output. This is the server name in the link. If internet explorer displays nothing then it means server is up. If I get internet explorer cannot display the webpage then it means server is down.
Below is the code to open the IE
Process.Start("https://foo.com");
If internet explorer shows an empty page then server is up else server down.
And want to know how the browser closes automatically?
using(WebClient client = new WebClient())
{
string pageData;
try
{
pageData = client.DownloadString(yourAddress);
}
catch(Exception e)
{
//something went wrong. Maybe the site is down?
}
//does pageData have expected content?
}
If you just need to get the value of a web page, you should use something more lightweight, for example, HttpClient (http://pfelix.wordpress.com/2012/01/11/the-new-net-httpclient-class/). This way you won't have to worry about cleaning up external processes like internet explorer.
If you insist on using IE for this, Process.Start(string) returns an instance of System.Diagnostics.Process, so you can call .Close() on that returned instance.
.
var ieProcess = Process.Start("https://foo.com");
bool isServerUp = IsServerUp(ieProcess);
ieProcess.Close();

When you type javascript:window.open('http://stackoverflow.com') in chrome's navigation bar, it opens new tab. I want same, but when running chrome from cmd:
var process = Process.Start("chrome.exe",
"javascript:window.open('http://stackoverflow.com')");
I'm doing this because I want to close that window later from inside it with window.close(). If I open website directly, error is thrown:
Scripts may close only the windows that were opened by it.
If you just want chrome to open a new tab to a page, why not try:
var process = Process.Start("chrome.exe", "http://stackoverflow.com");
If you just want to close the window later with JS, what about:
window.open(location, '_self', '');
window.close();
Note, you cannot automatically add the javascript prefix to a chrome URL, even with copy and paste - this is a security feature.

i am working on a windows form application in which i have to make an autologin window.i want that when user desktop connects with internet, Automatically login must be occur. My Desktop application is connected with online database.
Can Any body tell me that what is the procedure to do that.
Please help me i am stucked badly in that.
Thanks in Advance,
Take a look at the System.Net.NetworkInformation Namespace. In particular the NetworkChange class.
Example:
NetworkChange.NetworkAvailabilityChanged += (sender, networkAvailabilityEventArgs) =>
{
if (networkAvailabilityEventArgs.IsAvailable)
{
// Network is available
// Try to open a database connection
}
else
{
// Network is not available
// Stop trying to open a database connection, or clean up existing connections
}
};
edit
You can also call NetworkInterface.GetIsNetworkAvailable() to get the same information on-demand.
if (NetworkInterface.GetIsNetworkAvailable())
{
// Network is available
// Try to log on
}
else
{
// Network is not available
// Do nothing
}
Keep trying to connect to the database until you don't get any error (or at least you can reach the database).
You could also try telnet-ing the remote port, but you can't be sure there's one (if you use SQL Server it's possible you're using Named pipes or other protocols)
i have issue in cross browser testing using codedui.
Using below code,
Process.Start("firefox", url);
BrowserWindow.CurrentBrowser = "firefox";
Browser = BrowserWindow.Launch(new System.Uri(url));
Keyboard.SendKeys("^{0}");
all code developed in IE . but now i have to execute code in firefox or chrome.I am going to execute the code in forefox.I am using this code here
Browser = BrowserWindow.Launch(new System.Uri(url));
in this line getting error like "An error occurred while connecting to Firefox".how to resolve this issue?I installed selenium components also. if i remove this line I am getting diffrent error like " Unable to find browser"...Please help.
Out of the box Visual Studio doesn't support cross browser CodedUI testing.
You're going to need to install Selenium components to allow for cross browser testing in Visual Studio.
Details on that can be found here:
http://blogs.msdn.com/b/visualstudioalm/archive/2012/10/30/introducing-cross-browser-testing-with-coded-ui-tests.aspx
Selenium components can be found here:
http://visualstudiogallery.msdn.microsoft.com/11cfc881-f8c9-4f96-b303-a2780156628d
Looks like CodedUI doesn't support playback on very many different browsers http://msdn.microsoft.com/en-us/library/dd380742(VS.100).aspx
There are some other tools out there http://watin.org/ is one, but I can't find anything myself that will really solve your problem.
Try
BrowserWindow.CurrentBrowser = "firefox";
BrowserWindow WebApp;
WebApp.CopyFrom(BrowserWindow.LaunchUrl(new System.Uri(url)));
I set up something similar to the following and it works well (I hand code everything, bypassing the UIMap).
public class WebApp : BrowserWindow
{
private string _url;
public WebApp(string url)
{
//define search properties using this keyword so the web application can be treated as a browser
_url = url;
BrowserWindow.CurrentBrowser = "Chrome";
this.CopyFrom(BrowserWindow.Launch(new Uri(url));
}
}
You can overload the constructor, of course, by adding a parameter for the browser to use or whether to start up the browser or not.
By setting up the web application as a BrowserWindow, you can have one open and ready and the playback engine should find it. I find this helps when working on tests (in IE).
Just a reminder, you do need the Selenium plug-in and that plug-in will only work for playback, not recording.
Cheers!
In our environment, we set up the Launch() method by doing the following:
public void LaunchBrowser(string uri)
{
BrowserWindow.CurrentBrowser = "firefox";
BrowserWindow myBrowser = BrowserWindow.Launch(new System.Uri(uri));
}
One thing to note is that if there is a firefox process already running in the background, the WebDriver will not launch a new instance, so be sure that all instances of firefox are shut down before the LaunchBrowser() is called. I've found that there are Java plugins that can keep it running in the background, so try to disable those that you don't need. Another good place to look, if you check your Task Manager and this is the case, is here.
I'm trying to use Selenium WebDriver to automatically login in to a site with a user-name and password. I've done my research and I don't believe this feature is supported by WebDriver, so I need to find another way. The site I'm trying to automate logging into is located here.
When prompted to login a popup window comes up that doesn't seem to be part of the browser. I'm using Firefox and Chrome. It seems Windows API may be required? I already tried passing the credentials in the URL but that didn't work. Also tried sendkeys, but received a Windows exception that the application was not accepting Windows messages. I also tried switching the current handle using driver.windowhandles but the popup doesn't seem to be a new handle.
Does anybody have any ideas? I'm kinda stuck. The preliminary code to get to the popup window is:
IWebDriver driver = new FirefoxDriver();
driver.Navigate().GoToUrl("http://www.portal.adp.com");
string currentWindow = driver.CurrentWindowHandle;
IWebElement userLogin = driver.FindElement(By.Id("employee"));
userLogin.Click();
The popup you are seeing is prompted by web server and is a authentication prompt. Selenium doesn't support this operation.
One of the way to handle this limitation is to pass user and password in the url like like below:
http://user:password#example.com
More info available here : http://aleetesting.blogspot.in/2011/10/selenium-webdriver-tips.html
I wanted my answer out there because I think I've solved it. This answer does not require passing the credentials through the URL (for those of you that are unable to like me). It also does not require any custom Firefox Profiles or extensions to be installed or included with the solution or installed onto the browser eliminating cross-machine compatibility issues.
The issue with me was that the authentication could not be completed via passing the credentials through the URL because the login was behind a proxy.
So, I turned to windows automation toolkits and found AutoIT. Using AutoIT and Selenium, you can login automatically by sending the username and password to the windows dialog that appears. Here's how (note the steps below are for c#:
1 - Download AutoIT from http://www.autoitscript.com/site/autoit/downloads/
2 - Add the autoit .dll to your project references.
Right click on references, select Add Reference. Next click the browse button and browse to the dll location (most default installations it will be c:\Program Files (x86)\AutoIt3\AutoItX\AutoItX3.dll), and add to project.
3 - use AutoIT and Selenium like this (assuming your web driver is already initialized):
//Initialize AutoIT
var AutoIT = new AutoItX3();
//Set Selenium page load timeout to 2 seconds so it doesn't wait forever
Driver.Manage().Timeouts().SetPageLoadTimeout(TimeSpan.FromSeconds(2));
//Ingore the error
try
{
Driver.Url = url;
}
catch
{
return;
}
//Wait for the authentication window to appear, then send username and password
AutoIT.WinWait("Authentication Required");
AutoIT.WinActivate("Authentication Required");
AutoIT.Send("username");
AutoIT.Send("{TAB}");
AutoIt.Send("password");
AutoIT.Send("{ENTER}");
//Return Selenium page timeout to infinity again
Driver.Manage().Timeouts().SetPageLoadTimeout(TimeSpan.FromSeconds(-1));
Anyway, that's it, and it works like a charm :)
Also note that there are some special characters that need to be escaped in AutoIT using the sequence "{x}". For example, if your password is "!tRocks", you'd need to pass it into AutoIT as "{!}tRocks".
Happy automating.
FirefoxProfile profile = new FirefoxProfile();
profile.SetPreference("network.http.phishy-userpass-length", 255);
profile.SetPreference("network.automatic-ntlm-auth.trusted-uris", hostname);
Driver = new FirefoxDriver(profile);
hostname is your URL (example.com) then try to
Driver.Navigate().GoToUrl(http://user:password#example.com);
I just got done working on a prototype project that is supposed to handle exactly this kind of situation.
It utilizes BrowserMob, a popular open source proxy, to perform the authentication.
SeleniumBasicAuthWrapper Hope it helps! It is still a work in progress, but hopefully we'll get any kinks or defects ironed out in the near future.
Is there a way I could change the download folder of the default web browser using c#.
Concurring with other's comments, you can only do it in a desktop app if you have the right permissions.
Here's some sample code to find out the default browser of the system (from this post):
private string getDefaultBrowser()
{
string browser = string.Empty;
RegistryKey key = null;
try
{
key = Registry.ClassesRoot.OpenSubKey(#"HTTP\shell\open\command", false);
//trim off quotes
browser = key.GetValue(null).ToString().ToLower().Replace("\"", "");
if (!browser.EndsWith("exe"))
{
//get rid of everything after the ".exe"
browser = browser.Substring(0, browser.LastIndexOf(".exe")+4);
}
}
finally
{
if (key != null) key.Close();
}
return browser;
}
However, things get tricky from here. Different browsers have different ways of saving the default location.
E.g.,
IE may store it in registry (usually under HKEY_CURRENT_USER\ Software\ Microsoft\ Internet Explorer)
FF stores it in prefs.js in Profile folder (checkout this post to get to it via code)
Not sure about Chrome and Safari
but you get the idea.
Not sure what your end goal is, but from a UX standpoint, I think the best thing to do would be to ask user to specify the Download directory (in other words, you expose a Setting in your App for the default download location).
To expand on Ash's comment - if you're within a web app, no. If you're a desktop app, and you have sufficient permissions (i.e. running as Administrator), probably. But you'd need to find the default browser (from the registry presumably) and know how to set the download folder for each popular browser, or every browser you want to work with.
Where are you trying to do this from? If you mean "someone hits our website and ...", the answer is no, as anything you run is in a security context. You can certainly suggest the user changes the folder, but you are stuck.
Assuming you are not a web application, you have options. The main user download directory is located at X under the key {374DE290-123F-4565-9164-39C4925E467B}. Yeah, that sounds like a lot of fun. You can learn how to hack the registry programatically here. But, the user can specify a specific folder in the browser, as well. This means you have to know what browser the user is using and hack it, or you can attempt to hack all.
The bad news is the app, running (most likely) in the user context, may not have administrator rights and be able to whack the registry keys to change the folder.
