I currently developing a ASP.NET web application.
The application is designed for Google Chrome. I would like to pop out IE when printing is involved because Chrome lack preview etc. at a button click the IE should open. Here's the code:
protected void btn_print_Click(object sender, EventArgs e)
{
System.Diagnostics.Process.Start("http://localhost/storeapp/printpage.aspx?orderno=" + Request.QueryString["orderno"].ToString() + "");
}
Here I have passed a particular orderno to the URL. But when I click nothing happens. I have set IE as default web browser. Why is this?
There is no error shown? Any ideas?
What you are trying to do will only open an IE window on the SERVER not on the client machine. You cannot (for obvious security reasons) start a process on the clients machine.
You cannot force a client browser to open a link in a different browser.
You cannot force server to open process on Client side, what you have now is opening it on the Server side which is not desired behavior I believe.

The WebBrowser control shipped with .NET 4.7 is throwing lots of JavaScript errors. For example, we tried with www.yahoo.com and we get multiple JavaScript errors. One such example is shown below:
If we browse the same link in internet explorer 11, we are not getting any error and browsing session goes smooth. Note that we already set Browser Emulation registry setting for IE 11. Used the Link to Set IE 11 Emulation. The Registry Key for the Emulation is:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
(For 64 bit machine)
Re-production steps
Create a Visual C# Windows Forms Application
Place Web-Browser Control and a Command Button in the Form
Add the Following code in the command button Handler:
private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Navigate("http://www.yahoo.com");
}
That is all. Once we click the command button, we have to respond to multiple JavaScript errors. How do we resolve this issue?
Note that we already have Browser Emulation for IE is set to 11 (in Registry). We do not want to suppress the Error, as we lose the service provided by the JavaScript. For example, click the “Cricket” button in the very top of the Yahoo page:
What I'm trying to do is to, from a Web Service (WCF), give a remote computer (the Web Service Consumer) the instruction to open its default Web Browser (be it Internet Explorer, Firefox, Chrome, etc.), navigate to a certain web page and keep monitoring the events of that browser so that I can capture a certain value from the Document Title at a certain point, and do stuff with it.
I'm already able to send the command to open Internet Explorer and navigate to a URL, from the Web Service to the remote computer (my consumer), but I don't like the approach since I can't monitor the Document.Title property for changes nor access its value at any given time. Here is an example:
using System.Diagnostics;
public void DoIt();
{
Process batchProcess = new Process();
batchProcess.StartInfo.FileName = "iexplore.exe";
batchProcess.StartInfo.Arguments = "http://whatever.com";
batchProcess.Start();
}
This opens up Internet Explorer on the remote machine and navigates to the Url I give it, but I can't keep watch for the Browser's Events or Properties Values....
Can somebody help? ;-)
I don't think you can access information in one application (the web browser) from another (the WCF client) like that, and it's certainly not possible to do it without knowing what the user's default browser is.
You might have more luck using a WebBrowser control (WPF or Windows Forms), which embeds Internet Explorer's engine into the application and allows you access to the document title.
I want to write a program which recognizes when a browser is open and which do every time an action, when the user went to a website. For example:
The program is running as a system tray and starting automatically on windows startup. (this works)
Now the program runs an function, if the client open a random internet-browser (IE, Chrome, ...) which have the example-code MessageBox.Show("You opened a browser!").
If the user types for example "www.google.com" in the address bar and push [enter] the program should open an example-function like MessageBox.Show("You entered " + enteredURL) before the Website is loaded.
Thanks in advance for your help!
Take a look at the Navigating event:
Occurs before the WebBrowser control navigates to a new document.
It is possible to connect to an existing instance of IE, but you'll need to work with underlying the COM API (see here).
For other browsers there is no general mechanism: you'll need to work out if some API even exists browser by browser.
I'm using Selenium and NUnit to test multiple browsers - FF and Chrome work fine, but IE just opens up the browser to my Login page and just proceeds to hang there doing nothing.
I'm using the most recent versions of the Drivers. Anyone else have this problem, and hopefully a solution? IE is the browser that we really need to test.
Thanks much. :-)
Disable protected mode in IE browser and disable it for all four icon
1) Internet
2) trusted
3) Local Intranet
4) restricted site

I am working on a windows application, where i have to provide the user, a way to change the proxy settings by opening the IE settings window. Google chrome uses the same method, when you try to change the proxy settings in chrome, it will open internet explorer properties window with the connection tab selected.
I have observed that chrome is running run32dll.exe to achieve this, but it is also passing some arguments along with it
System.Diagnostics.Process.Start("rundll32.exe", "SomeArgumentsHere");
my only problem is i don't know what arguments it is passing.
To simplify my question, i want to know a way to open IE settings window with the connection tab selected, from my C#.net application
Update the following code worked for me
System.Diagnostics.Process.Start("inetcpl.cpl", ",4");
This is the complete command passed by Google chrome (obtained using Process Explorer):
"C:\Windows\system32\rundll32.exe" C:\Windows\system32\shell32.dll,Control_RunDLL C:\Windows\system32\inetcpl.cpl,,4
