Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the HtmlWindow.Error event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type HtmlWindow named HtmlWindow1. Then ensure that the event handler is associated with the HtmlWindow.Error event.

private void HtmlWindow1_Error(Object sender, HtmlElementErrorEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Description", e.Description );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "LineNumber", e.LineNumber );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Url", e.Url );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "Error Event" );
}

Private Sub HtmlWindow1_Error(sender as Object, e as HtmlElementErrorEventArgs) _ 
     Handles HtmlWindow1.Error

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Description", e.Description)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Handled", e.Handled)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "LineNumber", e.LineNumber)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Url", e.Url)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"Error Event")

End Sub

Remarks

If you are hosting an HTML document that contains frames, it might not be evident which frame is responsible for generating the error. Use this property to provide debugging information so that a developer can better narrow down the problem.
