I'm trying to download some PDF's using a WebBrowser. This URL contains an iframe with the src attribute set to this other URL, which in turn has a 302 redirect to this URL, which is a PDF file.
When I visit the first URL with a WebBrowser, it downloads and opens the file using Acrobat Reader. I would like to prevent this from happening because I'd like to automate the WebBrowser to visit many of these pages programmatically and don't want a bunch of Adobe Acrobat launching all over.
I have access to the DWebBrowserEvents2 and all of its events. One of the events getting fired was NavigateError, with the URL parameter pointing to the PDF file. I tried setting cancel to true, but the file was still being downloaded.
Is there any other way I can programmatically cancel the download?

I'm working on an Internet Explorer addon (IE11), using C#. I have by BHO & Button registered, and working. I'm trying to get the contents of the current tab when my button is pressed, WITHOUT issuing a second request for the resource.
With HTML, this is easy, I'm just using execScript to run some JavaScript which gets the page HTML.
Preferably, there would be a way to get the current pages content as a binary stream without issuing another request that works for HTML or PDF files (assuming the Adobe reader extension is installed), but I can't find any information about it.
I use WebBrower of microsoft to log into a website. I have no problem with logging in. I don't have the downloadable file url because the file is generated automatically.
How should I download file with out Save As popup to show ?
Work with the DOM (document object model) of the website find your download link via traversing the DOM exposed by the browser control via it's property
Document
it is a tree of elements that your after-login page consists of. There should be some element that you should invoke click on it and then handle OnNavigating (https://msdn.microsoft.com/en-us/library/system.windows.forms.webbrowser.onnavigating(v=vs.110).aspx) event of the control to get the generated download URL.
I have url like this
http://domainname.com/view/downloadfile?uname='ddd'&id=4
if we type the above url (not exactly the same ) in browser address bar it prompts open/save file dialog
my requirement is in button click without open/save dialog i need to download the file to my local disk location
Actually am working with webbrowser control .button is outside the webbrowser control
You could use the WebClient.DownloadFile method. Or if you don't want to save the file on the disk but manipulate it in memory you could use the WebClient.DownloadData method.
I need to automate downloading of a file from this site http://stats.smith.com/reports/Default.aspx using C#. The problem is that a web-form needs to be submitted first then the download takes place immediately. I can simulate the web form submit and the buttom clicks. However, once the form is submitted I don't know how to capture requested file. There is no redirection to the uri of the downloaded file. If there was I would have used function download(uri, filename) in webclient or webbrowser.
If you use the WebRequest Class you can receive the response and save it as a file.
I want to stream a pdf from a directory on the server using an ASP.NET page. This works fine. The catch is that I want to pass Adobe Open Parameters to land on a specific page.
Adobe has parameters for this: http://url/filename.pdf#page=XX
But, I can't find out how to stream the file rather than call it through a URL and get the #page= param to work.
Anyone ever done this?
For anyone having the same problem, I was able to solve this issue. If you change the content disposition in the Response.AddHeader from attachment to inline, then setup your url as:
http://url/Downloader.aspx?fileid=XX#page=YY
This will work. Your aspx page will render the pdf in the browser and the page parameter will navigate to the appropriate page. Hope this helps!
