Fala pessoal, boa tarde, tudo bem?

Bom, o que eu estou precisando, basicamente, é fazer a diferença entre duas matrizes que contém texto e obter como resultado a diferença entre elas. Pra exemplificar melhor, eu tenho uma lista de itens (Matriz 1) que é uma lista fixa. Daí a Matriz 2 vai ser sempre uma lista variável que contém obrigatoriamente algum item da Matriz 1, mas não necessariamente todos.

Ao pesquisar na internet um código ou função que tivesse esse objetivo, me deparei com a seguinte função, porém não consigo fazer ela funcionar. Aparece o erro "Erro de compilação: Sub ou Function não definida" e as 5 primeiras linhas são marcadas em amarelo


Public Function GetArrayDifference( _
      ByVal SourceArray1 As Variant, _
      ByVal SourceArray2 As Variant, _

   ) As Variant

' for the parameter Sorted. The returned array is always sorted in ascending
' order.

Boa tarde Felipe....

É um pouco mais complicado analisar o problema apenas visualizando o código, sobretudo quando é um código extenso assim....

Mas de qualquer forma, posso adiantar que seu código está incompleto... existem funções sendo chamadas aí que não fazem parte do código.. por exemplo a função IsOneDimensionArray, que não encontrei em nenhum lugar do código.

Provavelmente está faltando uma parte dessa programação.

Tente enviar o arquivo para análise ou verifique se o código que vc enviou está completo...

Abraços...

Espero ter ajudado.

Se ficou como vc queria... não esqueça de marcar essa mensagem como tópico resolvido e mandar um TKS.

Abraços

Como disse o colega, somente pelo código e um tanto quanto dificil ; porem no chutometro; acho que (por exemplo) IsOneDimensionArray e SortArray são functions auxiliares que deveriam ser incorporadas/copiadas ao seu projeto. Verifique na origem essas funções

Existem mil maneiras de preparar Neston. Invente a sua!

Pessoal, obrigado pelas respostas.

Vocês tinham razão, existiam funções sendo chamadas que não faziam parte do código.

Eu consegui o código completo, ele constrói 4 funções relacionadas a Matrizes. A que me interessava era justamente essa, de achar a diferença entre as matrizes, porém quando eu executo ela, ela não se propõe a fazer oque fala, somente retorna o primeiro valor. Vou colar o código aqui caso vocês queiram testar. Para que as fórmulas funcionem, é só colar ele inteiro no VBA
