How do I pass strings (Username and Password) in the default web browser installed instead of using Web Browser Control

I am actually working on a login project for a specific website, instead of going to the website to enter the login credentials (Username an Password) It would be much easier for my customer to enter those credentials from my Windows Forms Application C#. I have accomplished this using the built in feature of Windows Forms Application using the WebBrowser Control. However, I want to go further and do this in a customer's default web browser rather than taking advantage of the Web Browser Control that is inside WinForms Application. DropBox has done this in their Windows and Mac applications. How can I do this?

The following code implemented in C# with WebBrowser Control feature enabled:

Username box taken from the site: "_ctl0_PlaceHolderMain_Loginapp2_txtLoginUsername"
Password box taken from the site: "_ctl0_PlaceHolderMain_Loginapp2_txtLoginPassword"

Login Button taken from the site: "_ctl0_PlaceHolderMain_Loginapp2_btnLoginLogin"

C#

using System.Windows.Forms.HtmlElement;


HtmlElementCollection theElementCollection;
                    theElementCollection = Browser.webBrowser1.Document.GetElementsByTagName("input");
                    foreach (HtmlElement curElement in theElementCollection)
                    {
                        if ((curElement.GetAttribute("id").ToString() == "_ctl0_PlaceHolderMain_Loginapp2_txtLoginUsername"))
                        {
                            curElement.SetAttribute("Value", id.Text);
                        }
                        else if ((curElement.GetAttribute("id").ToString() == "_ctl0_PlaceHolderMain_Loginapp2_txtLoginPassword"))
                        {
                            curElement.SetAttribute("Value", pw.Text);

                        }
                    }
                    theElementCollection = Browser.webBrowser1.Document.GetElementsByTagName("input");

                    foreach (HtmlElement curElement in theElementCollection)
                    {
                        if (curElement.GetAttribute("id").Equals("_ctl0_PlaceHolderMain_Loginapp2_btnLoginLogin"))
                        {
                            curElement.InvokeMember("click");

                        }
                    }

Thanks Wes Aday, but I'm asking for the implementation, not an overview.

Right. As you have been told before, we don't write code to order.

Well why did CodeProject existed if that's the case?

CodeProject - For those who code, not for a lazy look for someone to code something for him

There is no universal method for doing this. Not every browser exposes an API to use to inject values into a loaded page.

How come DropBox has done something similar to what I was asking for?

Dave Kreskowiak 15-Jul-14 23:48pm

I don't use DropBox.

Probably because they went through the pain of researching every browsers support for this an implemented separate support modules for each browser they wanted to support.

Hmmm you're right
