Download pdf with WebBrowser without opening a new browser

Hi,

I'm trying to use a webbrowser in a C# MVC web application to download a pdf file.

I have to login and after logging in I must emulate the click of a button to download the pdf which is generated in the moment.

My problem is that the program tries to open a new webbrowser and I lose the login credentials, so I need to download the pdf without opening a new webbrowser.

Can anyone please help me?

Thank you very much.

hi

You are using windows forms app and need to download from the server. if it is use webclient
using System.Net;


string remoteUri = "http://www.contoso.com/library/homepage/images/";
string fileName = "ms-banner.pdf", myStringWebResource = null;
// Create a new WebClient instance.
WebClient myWebClient = new WebClient();
// Concatenate the domain with the Web resource filename.
myStringWebResource = remoteUri + fileName;
Console.WriteLine("Downloading File \"{0}\" from \"{1}\" .......\n\n", fileName, myStringWebResource);
// Download the Web resource and save it into the current filesystem folder.
myWebClient.DownloadFile(myStringWebResource,fileName);
Console.WriteLine("Successfully Downloaded File \"{0}\" from \"{1}\"", fileName, myStringWebResource);
Console.WriteLine("\nDownloaded file saved in the following file system folder:\n\t" + Application.StartupPath);

Hi,
I want to download because this are forms for paying taxes for several customers.
The actions are:
login to the site press the button to download the pdf file
logoff
login again with the credentials of another customer, press the button to download the pdf file
logoff
and so on

I may have to do this 1, 2, 50 times in a row, it depends. This is supposed to be an automated action

I send you the code I'm using in the next file.
Once again, thank you for your time.

Kindly display some code that you have.

Hi,
Thank you for your answer.
I can't attach the url of the file to download to the iframe because the file doesn't exist yet. When I click the button to download, the pdf is generated then, and opened in a new webbrowser.
In a web browser like chrome, for instance, I can configue the browser to not open pdf files in a new tab and the pdf is immediately downloaded. This is what I needed to do. So, what I needed to know is if it is possible to configure the WebBrowser component to not open pdf files in a new window and immediately download them.
Thank you very much.
