Waarde van eigenschap

De naam van het Help-bestand. Dit kan van het formulier C:\path\sample.chm of /folder/file.htmzijn.

Voorbeelden

In het volgende voorbeeld ziet u hoe u de HelpProvider klasse gebruikt om contextgevoelige Help weer te geven in een formulier met vier adresvelden. In het voorbeeld wordt de SetHelpString tekst help-knopinfo gebruikt. Wanneer u de contextgevoelige Help-knop gebruikt en op de Help-cursor in een adresveld klikt, wordt de Help-knopinfo weergegeven met de opgegeven tekst. Wanneer u op de toets F1 drukt met de focus in een adresveld, wordt het mspaint.chm Help-bestand weergegeven omdat de HelpNamespace eigenschap is ingesteld op mspaint.chm. De SetShowHelp methode wordt aangeroepen voor elk adresbeheer om te bepalen of er Help-inhoud beschikbaar is.
