Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ChangeUICues 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 ToolStripDropDown named ToolStripDropDown1. Then ensure that the event handler is associated with the ChangeUICues event.

private void ToolStripDropDown1_ChangeUICues(Object sender, UICuesEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ShowFocus", e.ShowFocus );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ShowKeyboard", e.ShowKeyboard );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ChangeFocus", e.ChangeFocus );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ChangeKeyboard", e.ChangeKeyboard );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Changed", e.Changed );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ChangeUICues Event" );
}

Private Sub ToolStripDropDown1_ChangeUICues(sender as Object, e as UICuesEventArgs) _ 
     Handles ToolStripDropDown1.ChangeUICues

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ShowFocus", e.ShowFocus)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ShowKeyboard", e.ShowKeyboard)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ChangeFocus", e.ChangeFocus)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ChangeKeyboard", e.ChangeKeyboard)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Changed", e.Changed)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"ChangeUICues Event")

End Sub
