数组 – VBA函数调用VBA sub将打印数组打印到工作表

目前我有一个用户定义的函数,它运行几个涉及矩阵生成的例程.要检查这些矩阵是否已正确生成,我想将它们放在工作表上.用户定义的函数工作正常,我已经在我想要找出数组中的内容的地方添加了以下内容:

Call CheckArray(TestArray)

上面的’TestArray’取决于我想看的数组.

‘CheckArray’子程序如下:

Sub CheckArray(MyArray As Variant)
MatrixRows = UBound(MyArray, 1)
MatrixCols = UBound(MyArray, 2)

MsgBox MyArray(11, 2)
MsgBox "Matrix size = " & MatrixRows & " rows x " & MatrixCols & " columns"

ActiveWorkbook.Worksheets("Check array").[A1].Resize(MatrixRows, MatrixCols) = MyArray
End Sub

请注意,我在那里放置了两个MsgBox命令来检查sub是否正确调用并且它正在工作,它是什么.此外,它返回了我所请求的特定位置的值,并且还说明了我正在查看的特定矩阵的大小,因此数据似乎确实被正确读取 – 问题在于随后从新子写入.

当我包含最后一行时,它不会将我的数组打印到工作表中,它也会阻止用户定义的函数正常工作.有谁知道为什么这不起作用?

用户定义的函数可以调用打印到工作表的subs吗?有没有办法来解决这个问题?

最佳答案 总结一下:

当我使用在工作表的单元格中输入的用户定义函数时,我无法将数据导出到除该单元格之外的任何位置.但是,我可以在立即窗口中查看数组.

在MS Excel 2010中,可以在VBA编辑器(Alt F11)中找到立即窗口,然后单击视图 – >立即窗口(Ctrl G).

要将我的数组导出到立即窗口,我应该在我要查看的数组之后将其输入到我的代码中:

Call WriteArrayToImmediateWindow(MyArray)

其中’MyArray’是我的数组的名称,无论是什么.

然后,这将调用’WriteArrayToImmediateWindow’子,即:

Sub WriteArrayToImmediateWindow(arrSubA As Variant)

Dim rowString As String
Dim iSubA As Long
Dim jSubA As Long

rowString = ""

Debug.Print
Debug.Print "The array is: "
For iSubA = 1 To UBound(arrSubA, 1)
    rowString = arrSubA(iSubA, 1)
    For jSubA = 2 To UBound(arrSubA, 2)
        rowString = rowString & "," & arrSubA(iSubA, jSubA)
    Next jSubA
    Debug.Print rowString
Next iSubA

End Sub

编辑:

我决定在立即窗口中查看数组并不总是有用,我需要在Excel中查看以逗号分隔的数据.如果您想这样做,请按照以下说明操作:

要将数组导出到文本文件,您应该在要查看的数组后将其输入到代码中:

Call WriteToFile(MyArray)

其中’MyArray’再次是您要查看的数组的名称. ‘WriteToFile宏如下:

Sub WriteToFile(arrSubA As Variant)
'To export array to a text file
    'Setup
    Dim FSO As Object
    Dim ofs As Object
    Dim Output As Variant
    Dim rowString As String
    Dim iSubA As Long
    Dim jSubA As Long
    rowString = ""

    'Create file
    Set FSO = CreateObject("Scripting.FileSystemObject")
    Dim oFile As Object
    Set oFile = FSO.CreateTextFile("C:\Users\" & Environ$("username") & "\Desktop\Array.txt")
    oFile.Close
    For iSubA = 1 To UBound(arrSubA, 1)
        rowString = arrSubA(iSubA, 1)
        For jSubA = 2 To UBound(arrSubA, 2)
            rowString = rowString & "," & arrSubA(iSubA, jSubA)
        Next jSubA
        If Len(Dir("C:\Users\" & Environ$("username") & "\Desktop\Array.txt")) > 0 Then
            Set ofs = FSO.OpenTextFile("C:\Users\" & Environ$("username") & "\Desktop\Array.txt", 8, True)
        End If
        ofs.WriteLine rowString
        ofs.Close
    Next iSubA
End Sub

要在Excel中快速查看输出数组而不使用任何逗号,我建议将以下宏指定给按钮:

Sub OpenArrayFile()
'To open array text file in Excel
    Workbooks.OpenText Filename:="C:\Users\" & Environ$("username") & "\Desktop\Array.txt", Origin:= _
        xlMSDOS, StartRow:=1, DataType:=xlDelimited, TextQualifier:=xlDoubleQuote _
        , ConsecutiveDelimiter:=False, Tab:=True, Semicolon:=False, Comma:=True _
        , Space:=False, Other:=False, FieldInfo:=Array(1, 1), _
        TrailingMinusNumbers:=True
End Sub

希望这对其他人也有用!
