Managing key events in a WebBrowser control?

Question

I am currently using an application that plays ppt and performs flash control in WebBrowser Control.

In WebBrowser, I can hide the context menu with

 this.IsWebBrowserContextMenuEnabled = false; 

and capture the key event using

 this.PreviewKeyDown += new PreviewKeyDownEventHandler(IWebBrowser_PreviewKeyDown); 

but when playing ppt , both the context menu and the keystroke events do not work, that is, I see the context menu and arrow to make ppt change the slide.

Again, during flash playback, the context menu is displayed, and I can handle the key event. is there any other setting for it, is the same for any ( HTML , ppt , Flash , PDF ) reproduced in webBrowser?

Edit: 1 Here is my existing code

 class IWebBrowser : WebBrowser public IWebBrowser(RegionOptions options) { try { this.Width = 600; this.Height = 400; this.IsWebBrowserContextMenuEnabled = false; this.ScrollBarsEnabled = false; this.ScriptErrorsSuppressed = true; this.WebBrowserShortcutsEnabled = false; this.AllowNavigation = true; CreateContextMenu(); this.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(IWebBrowser_DocumentCompleted); this.PreviewKeyDown += new PreviewKeyDownEventHandler(IWebBrowser_PreviewKeyDown); } catch (Exception ex) { log.Error("IWebBrowser - ctor ", ex); } } private void CreateContextMenu() { ContextMenuStrip myContextMenu = new ContextMenuStrip(); this.ContextMenuStrip = myContextMenu; ToolStripMenuItem myFirstTooltip = new ToolStripMenuItem(); ToolStripMenuItem mySecondTooltip = new ToolStripMenuItem(); ToolStripMenuItem myThirdTooltip = new ToolStripMenuItem(); myFirstTooltip.Text = "Item One"; mySecondTooltip.Text = "Item Two"; myThirdTooltip.Text = "Item Three"; myContextMenu.Items.Add(myFirstTooltip); myContextMenu.Items.Add(mySecondTooltip); myContextMenu.Items.Add(myThirdTooltip); }

Follow these steps to get rid of the default context menu.

• Do what you did to hide the default context menu

  this.IsWebBrowserContextMenuEnabled = false;

• Add a ContextMenuStrip control to your window and give a name (say MyMenu)

• Set the ContextMenuStrip property for MyMenu for your browser

Now, regardless of the type of document displayed in your browser, it will only display your user menu.

Hope this helps!

All the best

You have to catch the PreviewKeyDown event in your WebControl where your ppt / flash is playing, and pick it up on the content page or something else.
