Nombre del archivo de Ayuda. Puede tener la estructura C:\ruta\ejemplo.chm o /carpeta/archivo.htm.
Ejemplos
En el ejemplo siguiente se muestra cómo usar la HelpProvider clase para mostrar ayuda contextual en un formulario que contiene cuatro campos de dirección. En el SetHelpString ejemplo se usa para establecer el texto información sobre herramientas de ayuda. Al usar el botón Ayuda contextual y hacer clic en el cursor ayuda en un campo de dirección, aparece la información sobre herramientas de ayuda con el texto especificado. Al presionar la tecla F1 con el foco en un campo de dirección, se muestra el mspaint.chm archivo de Ayuda porque la HelpNamespace propiedad se ha establecido mspaint.chmen . Se SetShowHelp llama al método para cada control de direcciones para identificar que tiene contenido de Ayuda disponible.
