I have a google webpage that has a BROWSE button. When one clicks it an openfile dialog appears and prompts the user to select a file for uploading.
The problem is that the client has a lot of files and field to complete so I first tried to automate this through a browser extension. All worked well besides the file uploading. It seems tht because of security reasons you can't make a browser extension, feed it the path of the filename, and automatically upload it.
I want to automate this upload, field-auto-completion process, INSIDE A .NET APPLICATION, How do I access webpage DOM objects in .NET?
Is there a .NET library that can sweep through and modify DOM nodes as easily as you could inside a browser extension with the added possiblily of automating the BROWSE button openDialog stuff?

I need to download a pdf file with Selenium. This pdf file is downloaded when a button is clicked. The URL of the file isn't accesible, the button submit a form and the server response directly with the file (without confirm dialog).
I'm using PhantomJS WebDriver (the project is in C#) because the application will be an Azure webapp, so I can't use ChromeDriver or similar. The problem is that PhantomJS can't deal with binary files, so when I simulate the click in the button the app doesn't download anything.
Any ideas??
P.D: Selenium is not only for the pdf download, the project do a lot of scrapping with it.
If you are using Azure and you are not able to fidn any solution, I would suggest greating a virtual machine with graphical interface so you can run an instance of ChromeDrive (or another one).
In my project, I have a fileupload control for user to upload their document and I want to provide a link to user to open their files.
steps:
after user upload a file, my web will create a link for it
when user click on that link, the container folder of that file will open.
For example, a file which its path is C:\Users\John\Downloads\jpg\a.jpg uploaded to the fileupload control. when user click on the link of that file, a folder C:\Users\John\Downloads\jpg will be opened.
To get the file path:
string filePath = FileUpload1.PostedFile.FileName; // file name with path.
So, how can I open a folder in client PC by C#?
For security reasons, browsers do not expose the local filesystem to the Javascript sandbox. What you're asking is not possible with Javascript or any other common browser technology that does not require a client install (like Flash or ActiveX). You definitely cannot get it in c# which runs on the server and has no knowledge of the client's filesystem.
I need to automate the download of a file from this site http://stats.smith.com/reports/Default.aspx?btnGo=View+Report. My problem is once I click on the submit buttom I lose control and a download dialog pops up. Is there a way to download the file using c# and avoid the download dialog? I'm currently using the WebBrowser object in the Forms assembly to navigate through the page.
Take a look at the WebClient class
If you want to save a downloaded file to the filesystem from a web browser, there must be user interaction. A web page does not have permission to muck about in a client's file system.
If you want to display the page in the browser, you can try removing the Content-Disposition=attachment;... server response header when the file is downloaded. This will only work if the client has the browser set to display such file types inside the browser.
Your question doesn't specify what you're using to download the file.
If you're asking if you can have a program that runs on a client (either a WinForms app, a console app, or a Windows Service) then you can download a file from a web site using the System.Net.WebClient class and calling the DownloadFile() method.
The accepted answer here (slightly different than you question, so it's not a duplicate) has a link to show how to download a file that requires an HTTP post first.
If you're trying to somehow automate Internet Explorer via a javascript from a web page you're hosting to force a file to download on a user without displaying the dialog box, then no. You can't.
The SL3 DataGrid has a download XLS column to download the details of the record in Excel format. On click of the Download button, first the user is prompted with a SaveFileDialog to select the file and then a WCF call is made to fetch the details of the selected record. Using 3rd party excel helper library, the records are added to an excel sheet and the file is saved.
The problem is that when the Session has timed out (say, due to idleness), the click functions perfectly well, prompting the user to specify the file to save, and then a redirect is made to the login page (as expected, since we are handling the not authenticated errors etc).
However, the user is now in an illusion that an empty Excel file has been downloaded.
So, is there a way to detect from Silverlight page, if the Session has timed out?
And thereby showing the SaveFileDialog only when the Session is available.
You can probably send the heartbeat from Silverlight to ASP.NET. This is very common issues in Ajax world as well. As you can use Javascript in Silverlight as well, you may want to check this solution Keeping ASP.NET Session Open / Alive
If you dont like to JS then you can either use HttpWebRequest or WebClient to communicate with asp.net ...
When you use the C#.Net wpf WebBrowser control to view html pages, and the user clicks on a link to a file with an unknown extension, the webbrowser tries to download this file.
On systems with no pdf viewer installed, webbrowser tries to download pdf files instead of either displaying them or warning the user that they need Adobe, etc.
I would like to detect when a webbrowser tries to download, so I can check if the file is pdf and then provide a download link.
Is this possible?
