// This example demonstrates how to use the KeyUp event with the Help class to display // pop-up style help to the user of the application. When the user presses F1, the Help // class displays a pop-up window, similar to a ToolTip, near the control. This example assumes // that a TextBox control, named textBox1, has been added to the form and its KeyUp // event has been connected to this event handler method. private: void textBox1_KeyUp( Object^ /*sender*/, System::Windows::Forms::KeyEventArgs^ e ) { // Determine whether the key entered is the F1 key. Display help if it is. if ( e->KeyCode == Keys::F1 ) { // Display a pop-up help topic to assist the user. Help::ShowPopup( textBox1, "Enter your first name", Point(textBox1->Right,this->textBox1->Bottom) ); } }
