调用从电子表格返回自定义类型的VBA函数 [英] Call VBA function that returns custom type from spreadsheet

问题描述

我有一个vba函数返回自定义数据类型，定义如下：

I have a vba function that returns a custom data type, defined as:

Public Type stockValue
        stock As String
        value As Double
End Type

我的问题是如何当我从电子表格单元格调用函数时处理这个问题？例如，我想要单元格显示股票值，我试过 = function（）。stock 不起作用

My question is how do I deal with this when i call the function from a spreadsheet cell ? for example, say i want the cell do display the stock value, i tried =function().stock and it doesn't work

任何帮助都不胜感激，谢谢！

any help is appreciated, thanks !

Function getLowestPnl(strat As String, rank As Integer) As stockValue

    Call Conecta_DB(conexao)
    Set registros = New ADODB.Recordset

    strSQL = "SELECT stock,sum([value]) FROM Reports.dbo.Entry WHERE idStrategy='" & strat & "' and idType=1 GROUP BY stock  ORDER BY sum([value])"
    'strSQL = "SELECT [finance],[sales],[management],[research],[administration] FROM [COS].[dbo].[Complementarity] WHERE [idCompany] =" & idCompany & " and [year]=" & year & " and [CEO]=1"

    registros.Open strSQL, conexao, adOpenStatic, adLockOptimistic

    parar = False
    If Not registros.EOF Then

        x = registros.GetRows()
        i = 0
        Do While parar <> True

            If i = (rank - 1) Then
                getLargestShortExp.stock = Trim(x(0, i))
                getLargestShortExp.value = x(1, i)
                parar = True
            End If
            i = i + 1
        Loop

    End If

    registros.Close
    getLowestPnl = ret
End Function

推荐答案

只返回Excel从用户定义的函数中理解的数据类型。 Excel不了解自定义数据类型。

You can only return data types that Excel understands from a user-defined function. Excel does not understand custom data types.

相反，您必须从自定义数据类型返回包含2个值的变体数组。然后你可以将数组输入到2个单元格中，或使用其他函数（如INDEX）从返回的数组中检索所需的值。

Instead you would have to return a variant array containing the 2 values from your custom data type. Then either you would array enter the function into 2 cells, or use another function such as INDEX to retrieve the value you wanted from the returned array.
