RESUMO<\/b><\/p>\n

Ao utilizar o componente E3DataAccess <\/b>em linguagens sem tipos (typeless), como o VBScript ou o Javascript, as chamadas do m\u00e9todo GetValue <\/i>retornam erro de tipos incompat\u00edveis (type mismatch). O problema acontece porque em linguagens sem tipos, os par\u00e2metros IN\/OUT<\/b> devem ser do tipo VARIANT. J\u00e1 no VBA, por exemplo, onde as vari\u00e1veis possuem tipos definidos, este problema n\u00e3o acontece.<\/p>\n

COMO REPRODUZIR O PROBLEMA <\/b><\/p>\n

Para simplificar, foi utilizado o pr\u00f3prio Elipse E3<\/b> para reproduzir o problema:<\/p>\n

\r\n\r\n\u00a0\u00a0\u00a0 Set <\/span>da = CreateObject<\/span>(\"E3DataAccess.E3DataAccessManager.1\"<\/span>)\r\n\u00a0\u00a0\u00a0 Dim <\/span>r, a, b, c\r\n\u00a0\u00a0\u00a0 r = da.GetValue(\"Dados.Tag.Value\"<\/span>, a, b, c)\r\n\u00a0\u00a0\u00a0 MsgBox <\/span>r\u00a0\u00a0\u00a0 <\/span><\/pre>\n
Uma mensagem de erro ser\u00e1 exibida: ‘Type mismatch: ‘da.GetValue”<\/i><\/p>\n
WORKAROUND<\/b><\/p>\n
    \n
  1. Utilize o controle em um ambiente VBA.<\/li>\n
  2. Atualize o E3 ou o controle para uma vers\u00e3o 4.5 ou superior.<\/li>\n<\/ol>\n

    \nSITUA\u00c7\u00c3O <\/b><\/p>\n
    A Elipse Software<\/b> confirmou que esta limita\u00e7\u00e3o <\/b>existe desde que o componente (E3DataAccess<\/b>) foi criado. O artigo Conectando uma p\u00e1gina HTML a um E3Server com a biblioteca de comunica\u00e7\u00e3o E3DataAccess utilizando JavaScript e VBScript<\/b><\/a> cont\u00e9m a corre\u00e7\u00e3o para vers\u00f5es 4.5<\/b> ou superiores<\/b>.<\/p>\n
    Nas vers\u00f5es 4.5 ou superiores, foram adicionados dois novos m\u00e9todos: ReadValue <\/i>e WriteValue<\/i>. Eles substituem GetValue <\/i>e o SetValue<\/i>, que consequentemente devem ser evitados.<\/p>\n
    ESTE ARTIGO APLICA-SE AOS SEGUINTES PRODUTOS <\/b><\/p>\n
    Vers\u00f5es do componente E3DataAccess <\/b>inferiores \u00e0 vers\u00e3o 4.5.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
