Este projeto também possui um programa base, onde é possível testar a conexão e compreender um pouco melhor como que a biblioteca funciona.
Ele está disponível na pasta "Sample program" do repositório do projeto, podendo ser acessado via: https://github.com/Nintersoft/DBManager/blob/master/sample%20program/. Lá, é possível baixar o código fonte que está contido em um arquivo zipado ou ainda explorá-lo no próprio GitHub.
Caso queira dar uma espiada, este é o exemplo compatível com a versão 2.0.5.6 da biblioteca (note que o repositório possui todas as dependências necessárias para compilá-lo):
