smo database herstellen

Ik heb met succes SMO gebruikt om de database te herstellen. Ik zal mijn code delen. Hoop dat het helpt. Deze oplossing heeft echter één voorbehoud, het is van mening dat u slechts één primair gegevensbestand hebt. Het is erg lastig om de log- en gegevensbestanden op elkaar af te stemmen en er kan op veel manieren iets misgaan. Hoe dan ook, probeer het me te laten weten, dit helpt.
