true if the control displays script error dialogs; otherwise, false. The default is false.

A reference to an implementation of the IWebBrowser2 could not be retrieved from the underlying ActiveX WebBrowser.

Set this property to true to debug Web pages that you display in the WebBrowser control. This is useful when you use the control to add Web-based controls and scripting code to your application. It is less useful when you use the control as a generic browser. When you have finished debugging your application, set this property to false to suppress script errors.

The following code example demonstrates how to use the ScriptErrorsSuppressed property to configure a WebBrowser control that has been added to a form.

For the complete code example, see How to: Add Web Browser Capabilities to a Windows Forms Application.

this->WebBrowser1->AllowWebBrowserDrop = false;
this->WebBrowser1->ScriptErrorsSuppressed = true;
this->WebBrowser1->WebBrowserShortcutsEnabled = false;
this->WebBrowser1->Dock = System::Windows::Forms::DockStyle::Fill;
this->WebBrowser1->IsWebBrowserContextMenuEnabled = false;
