I am working on a C# project where I am trying to send a excel file by WhatsApp. The problem is that whenever I run the code a new instance of command window is open, and a new window is opened for chrome every time I ran the code. Before running the code, I have already log-in to my WhatsApp account and wants to use the same window and tab to avoid logging each time. I have tried to use several ways to stop this but failed to achieve the result. Please correct the code. Please don't mind my bad English.
var options = new ChromeOptions();
options.AddArguments(#"user-data-dir=C:\Users\Umesh Aggarwal\AppData\Local\Google\Chrome\User Data");
IWebDriver driver = new ChromeDriver(#"C:\Users\Umesh Aggarwal\Desktop\chromedriver_win32", options);
////// Navigate to Whatsapp web
driver.Navigate().GoToUrl("https://web.whatsapp.com/");
IReadOnlyCollection<string> windowHandles = driver.WindowHandles;
// Find already opened window with Chrome
string chromeWindow = "";
foreach (string window in windowHandles)
{
driver.SwitchTo().Window(window);
if (driver.Title.Contains("Google Chrome"))
{
chromeWindow = window;
break;
}
}
// Switch to Chrome window
driver.SwitchTo().Window(chromeWindow);
// Get all open tabs in Chrome window
IReadOnlyCollection<string> tabHandles = driver.WindowHandles;
// Find already opened tab of Whatsapp web
string whatsappTab = "";
foreach (string tab in tabHandles)
{
driver.SwitchTo().Window(tab);
if (driver.Title.Contains("Whatsapp"))
{
whatsappTab = tab;
break;
}
}
//// Switch to Whatsapp tab
driver.SwitchTo().Window(whatsappTab);
Here is my selemium test:
[Test]
public void RunStepsTest()
{
using (var driver = new InternetExplorerDriver())
{
driver.Navigate().GoToUrl(Url);
ExecuteStep(driver, "start");
ExecuteStep(driver, "step1");
ExecuteStep(driver, "step2");
ExecuteStep(driver, "finish");
}
}
private void ExecuteStep(InternetExplorerDriver driver, string stepName)
{
var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
wait.Until(x => ExpectedConditions.ElementIsVisible(By.Id(stepName)));
var scrrenshot = driver.GetScreenshot();
scrrenshot.SaveAsFile(Path.Combine(ScreenshotDirectory, stepName + ".jpg"), ScreenshotImageFormat.Jpeg);
var link = driver.FindElement(By.Id(stepName));
link.SendKeys(Keys.Enter);
}
Most of time this test fails on line
scrrenshot.SaveAsFile(Path.Combine(ScreenshotDirectory, stepName + ".jpg"), ScreenshotImageFormat.Jpeg);
with message "Paramter is not valid". What do I do wrong?
In Internet Explorer driver, it's intended to throw this error .
From Github bug tracking :
Because of the limitations of how the IE driver is forced to work in
order to take full-DOM screenshots, screenshots are only supported for
browser windows viewing HTML documents. This is entirely as intended
by the driver (regardless of the behavior of Chrome or Firefox). The
driver is forced by the constraints of the IE browser itself.
Accordingly, I'm closing this as "working as intended".
If you are allowed to use other driver, you can try Firefox or Chrome Driver to have screenshot.
Try this code like this:
Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
ss.SaveAsFile("e:\\pande", System.Drawing.Imaging.ImageFormat.Jpeg);
I've read all prior posts and tried all suggestions. I've verified the page is loading via taking a screenshot. It's there. I have a 30 second implicit wait in place, which PhantomJS waits for. I have a fully qualified URL. And i've tested the same simple code snippet below with ChromeDriver and it works by flipping to that driver. Any ideas?
[TestClass]
public class UnitTest1
{
[TestMethod]
public void TestMethod1()
{
var d = new PhantomJSDriver();
//var d = new ChromeDriver();
try
{
var s = "abc";
d.Manage().Window.Maximize();
d.Manage().Timeouts().ImplicitlyWait(System.TimeSpan.FromSeconds(10));
d.Navigate().GoToUrl("http://www.google.com");
var e = d.FindElement(By.Name("q"));
e.SendKeys(s);
e.Submit();
Assert.AreEqual<String>(s + " - Google Search", d.Title);
}
catch(Exception e)
{
((ITakesScreenshot)d).GetScreenshot().SaveAsFile("c:\\exception.png", System.Drawing.Imaging.ImageFormat.Png);
Console.WriteLine(d.PageSource);
throw e;
}
finally
{
d.Quit();
}
}
Google may response with different HTML code depending on user agent and/or viewport size. Set a viewport of a desktop browser (like 1280x1024) to get a desktop version, whereas default PhantomJS viewport of 400x300 gets a lighter mobile version.
On how to change viewport size, see https://stackoverflow.com/a/23840494/2715393
I can't seem to get past this exception on my coded UI project for a window dialog box. I've tried using always search and some other options. I was trying to use the option of open a window dialog button but that didn't seem to work since i did not see the open button only "OK" and a few ones that didn't pertain to what i was trying to do.
I see one of my window is returning 5 windows, I'm trying to use the code Order Of overcation but that doesn't seem to work.
Currently here is my latest code which is still not working and still giving me the same exception error
WinWindow myDialogBox = new WinWindow();
myDialogBox.FilterProperties.Add(WinWindow.PropertyNames.OrderOfInvocation, "5");
myDialogBox.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
myDialogBox.SearchProperties[WinWindow.PropertyNames.ClassName] = "DirectUIHWND";
myDialogBox.SearchProperties[WinWindow.PropertyNames.ControlId] = "0";
myDialogBox.DrawHighlight();
WinWindow MyOpbenButton = new WinWindow(myDialogBox);
// myDialogBox.SearchProperties.Add(WinWindow.PropertyNames.OrderOfInvocation, "0");
MyOpbenButton.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
MyOpbenButton.SearchProperties[WinWindow.PropertyNames.Name] = "&Open";
MyOpbenButton.SearchProperties[WinWindow.PropertyNames.ClassName] = "Button";
//MyOpbenButton.SearchProperties[WinWindow.PropertyNames.ControlId] = "0";
MyOpbenButton.DrawHighlight();
//Testing this window produces 5 window with the same name and
control ID.
WinWindow matchingWindows = new WinWindow(myDialogBox);
matchingWindows.SearchProperties.Add("Name", "&Open");
// matchingWindows.SearchProperties.Add("ControlId", "0");
matchingWindows.SearchProperties.Add("ClassName", "Button");
UITestControlCollection windowsFound = matchingWindows.FindMatchingControls();
WinPane MyOpbenPane = new WinPane(MyOpbenButton);
MyOpbenPane.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
//MyOpbenPane.SearchProperties[WinPane.PropertyNames.Name] = "Open";
MyOpbenPane.SearchProperties[WinPane.PropertyNames.ClassName] = "Button";
// var myDialog = sharedControls.UIWindowsInternetExploWindow.UIWindowsInternetExplo_Open_Save_Dialog_LinksPage.UIItemWindow;
MyOpbenPane.DrawHighlight();
return MyOpbenPane;
The error message that this is producing is the following:
Another control is blocking the control. Please make the blocked
control visible and retry the action. Additional Details:
\r\nTechnologyName: 'MSAA'\r\nName: '&Open'\r\nClassName:

I used the test builder to get around this issue.
I found that the dialog screen was being captured with the
classname of 32770. I also found that i could not pass off my browser window to window from there i hand coded the remaining screen using the test builder.
here is the code below.
WinWindow window = new WinWindow();
window.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
window.SearchConfigurations.Add(SearchConfiguration.VisibleOnly);
window.SearchProperties[WinWindow.PropertyNames.ClassName] = "#32770";
window.SearchProperties[WinWindow.PropertyNames.Name] = "Windows Internet Explorer";
window.WindowTitles.Add("Windows Internet Explorer");
//window.DrawHighlight();
WinCustom myDialogBox = new WinCustom(window);
myDialogBox.SearchConfigurations.Add(SearchConfiguration.VisibleOnly);
myDialogBox.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
myDialogBox.SearchProperties[WinCustom.PropertyNames.ControlType] = "Dialog";
myDialogBox.SearchProperties[WinCustom.PropertyNames.Name] = "Windows Internet Explorer";
myDialogBox.WindowTitles.Add("Windows Internet Explorer");
//myDialogBox.DrawHighlight();
WinWindow myDialogwindow = new WinWindow(window);
myDialogwindow.SearchConfigurations.Add(SearchConfiguration.VisibleOnly);
myDialogwindow.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
myDialogwindow.SearchProperties[WinWindow.PropertyNames.AccessibleName] = "Windows Internet Explorer";
myDialogwindow.SearchProperties[WinWindow.PropertyNames.ClassName] = "DirectUIHWND";
myDialogwindow.WindowTitles.Add("Windows Internet Explorer");
return myDialogwindow;
I run into this a lot. I have an application on which the tabs always get reported as hidden, even though they're clearly visible. What has worked well for me so far has been to use keyboard.sendkeys to send keystrokes that select the tab.
I'm having an issue with automating the process of downloading a file from a website. The website has a Java button, that when clicked, triggers the download of an Excel file. I'm using the most recent build of Watin (v2.1).
I've managed to get Watin to log into the website, navigate to the appropriate page, change parameters on the page, and click the button to start the download.
However, when the download has completed, the IE9 download box appears, and nothing happens, until Watin timesout.
I'd appreciate any suggestions as I can't see any way of downloading a file, or getting it to save the file. Even if it passed 'Alt+S' to the page, that would save it. I've tried running it through WatinTestRecorder and that doesn't prompt for saving.
using (var browser = new IE(sLogin))
{
browser.AddDialogHandler(new OKDialogHandler());
browser.AddDialogHandler(new DialogHandlerHelper());
browser.AddDialogHandler(new ConfirmDialogHandler());
browser.AddDialogHandler(new ReturnDialogHandlerIe9());
browser.TextField(Find.ByName("txtUserID")).TypeText("username");
browser.TextField(Find.ByName("txtPassword")).TypeText("password");
browser.Button(Find.ByName("btnLogin")).Click();
browser.WaitForComplete();
browser.GoTo(targetUri);
browser.SelectList("ctl00_phFormContent_ucOptionParam0_lst").SelectByValue("4");
browser.Button(Find.ByName("ctl00$phFormButtonBar$btnRun")).Click();
browser.WaitForComplete();
//Some code to download the file here!
}
This should be supported since version 1.1.0.4000. The release notes for that version aren't online anymore (http://watin.org/documentation/), but I found it in Googles cache (http://svn6.assembla.com/svn/ci-samples/dotnet/watir/website/releasenotes-1-1-0-4000.html)
It should be something like:
using(IE ie = new IE(someUrlToGoTo))
{
FileDownloadHandler fileDownloadHandler = new FileDownloadHandler(fullFileName);
ie.AddDialogHandler(fileDownloadHandler);
ie.Link("startDownloadLinkId").Click();
fileDownloadHandler.WaitUntilFileDownloadDialogIsHandled(15);
fileDownloadHandler.WaitUntilDownloadCompleted(200);
}
EDIT:
After the comments below, this answer was accepted. So I'm assuming the following code works (which is taken from the link to SourceForge in my last comment, notice the ClickNoWait):
using(IE ie = new IE(someUrlToGoTo))
{
FileDownloadHandler fileDownloadHandler = new FileDownloadHandler(fullFileName);
ie.AddDialogHandler(fileDownloadHandler);
ie.Link("startDownloadLinkId").ClickNoWait();
fileDownloadHandler.WaitUntilFileDownloadDialogIsHandled(15);
fileDownloadHandler.WaitUntilDownloadCompleted(200);
}
The accepted answer did not work for me because IE 9 pops up a "Notification" you have to navigate before you can get to the actual Save As dialog (and WatiN cannot handle notifications automatically). I followed Borris Pavlov's link which did a good job showing the way. I cleaned up the code a bit that was posted there and this was the resulting file:

See the comment in the ControlSaveDialog method for info on how to make this work as a debug build (VS settings).
I actually only tested the "Save As" operation so I hope the other works (it seems that the original poster added the "Save As" as an afterthought so my guess is that he tested the "Save" operation more thoroughly).
To call this you can use some code like:
Link lastMp4Link = mp4Links[mp4Links.Count - 1]; //mp4Links is a WatiN.Core.LinkCollection
lastMp4Link.Click();
browser.DownloadIeFile(string.Format(#"c:\temp\myFile.blah")); //"browser" is a WatiN.Core.IE object
I just got word from the Watin-users mailing list that FileDownloadHandler is broken with IE9. There is no fix yet, however I uninstalled IE9 (roll back to IE8) and it has the old style dialog that is handled by WatiN.
Watin can't find download dialog and dialog buttons. It can resolve with this.
How to test file download with Watin / IE9?

After many revisions using WaitN, I ended up using Selenium. It gives you a ton more control over what is being processed and used and allows you to use more modern web browsers.
