HowTo Disable WebBrowser 'Click Sound' in your app only
.net, c#, winforms
Solution
I've noticed that if you use WebBrowser.Document.Write rather than WebBrowser.DocumentText then the click sound doesn't happen.
So instead of this:
webBrowser1.DocumentText = "<h1>Hello, world!</h1>";
try this:
webBrowser1.Document.OpenNew(true);
webBrowser1.Document.Write("<h1>Hello, world!</h1>");
Problem
The 'click sound' in question is actually a system wide preference, so I only want it to be disabled when my application has focus and then re-enable when the application closes/loses focus. Originally, I wanted to ask this question here on stackoverflow, but I was not yet in the beta. So, after googling for the answer and finding only a little bit of information on it I came up with the following and decided to post it here now that I'm in the beta. ``` using System; using Microsoft.Win32; namespace HowTo { class WebClickSound { /// <summary> /// Enables or disables the web browser navigating click sound. /// </summary> public static bool Enabled { get { RegistryKey key = Registry.CurrentUser.OpenSubKey(@"AppEvents\Schemes\Apps\Explorer\Navigating\.Current"); string keyValue = (string)key.GetValue(null); return String.IsNullOrEmpty(keyValue) == false && keyValue != "\"\""; } set { string keyValue; if (value) { keyValue = "%SystemRoot%\\Media\\"; if (Environment.OSVersion.Version.Major == 5 && Environment.OSVersion.Version.Minor > 0) { // XP keyValue += "Windows XP Start.wav"; } else if (Environment.OSVersion.Version.Major == 6) { // Vista keyValue += "Windows Navigation Start.wav"; } else { // Don't know the file name so I won't be able to re-enable it return; } } else { keyValue = "\"\""; } // Open and set the key that points to the file RegistryKey key = Registry.CurrentUser.OpenSubKey(@"AppEvents\Schemes\Apps\Explorer\Navigating\.Current", true); key.SetValue(null, keyValue, RegistryValueKind.ExpandString); isEnabled = value; } } } } ``` Then in the main form we use the above code in these 3 events: - Activated - Deactivated FormClosing ``` private void Form1_Activated(object sender, EventArgs e) { // Disable the sound when the program has focus WebClickSound.Enabled = false; } private void Form1_Deactivate(object sender, EventArgs e) { // Enable the sound when the program is out of focus WebClickSound.Enabled = true; } private void Form1_FormClosing(object sender, FormClosingEventArgs e) { // Enable the sound on app exit WebClickSound.Enabled = true; } ``` The one problem I see currently is if the program crashes they won't have the click sound until they re-launch my application, but they wouldn't know to do that. What do you guys think? Is this a good solution? What improvements can be made?
