对于在excel vba中的目录中进行选择性循环，哪种方法是最好的

IO希望检查路径主目录/ABC*/Y/XY*/*.edf中的所有edf文件，然后检查文件中的特定短语，如果找到，则检查其他短语，依此类推，然后在电子表格中填充数据。我试图通过三种方法来实现这一点，但在每种方法中都遇到了一些问题。你们中的任何人都可以通过代码告诉我哪里错了，哪种方法最好（如果有的话）。正如我之前的问题所造成的误解，我不希望任何人为我编写代码。我已经开始在vba上工作了三天，我有五天的时间来完成这个项目。这就是为什么如果有人能看一眼并告诉我哪里出了问题，我将不胜感激

通过简单目录命令接近1 在FCS*的第一个循环中工作得很好，但第二个循环根本不工作，在第一次迭代时出现运行时错误。我知道这不是一个好方法，但万一其他方法不起作用

 Sub Iterate_Folders()
        Dim ctr As Integer
        Dim ctr1 As Integer
        ctr = 1
        ctr1 = 1
        Paths = "C:\Users\sobiakanwal\Downloads\QSHWRA\QSHWRA\ "   ' Path should always contain a '\' at end
        FirstDir = Dir(Paths, vbDirectory)   ' Retrieving the first entry.
        Do Until FirstDir = ""   ' Start the loop.
            If (FirstDir Like "FCS*") Then
                ActiveSheet.Cells(ctr, 15).Value = Paths & FirstDir
                Path1 = Paths & FirstDir & "\FUNCTION_BLOCK\DR*"
                ActiveSheet.Cells(ctr, 20).Value = Path1
                'ActiveSheet.Cells(ctr, 25).Value = SecondDir
                SecondDir = Dir(Path1, vbDirectory)
                Do While SecondDir = ""
                    ActiveSheet.Cells(ctr, 30).Value = "Hi"
                    If (True) Then
                        ctr1 = ctr1 + 1
                    End If
                    SecondDir = Dir()
                Loop
                ctr = ctr + 1
            Else

            End If
            FirstDir = Dir()   ' Getting next entry.
        Loop
        MsgBox (ctr1)
    End Sub

通过递归实现方法2 我在一个教程中找到了这方面的基本代码，然后对其进行了一些编辑，使其对我有利。这不是一般的工作方式，但以某种硬编码的方式给出了正确的答案。但是我想让你检查一下我在递归函数中遇到的问题，在这里我需要添加文件处理代码

Public Count As Integer

    Dim myFile As String, text As String, textline As String, posLat As Integer, posLong As Integer
    Dim k As Long, i As Long
    ReDim temp(2, 0)
    Count = 1
    If Right(FolderPath, 1) <> "\" Then
        FolderPath = FolderPath & "\"
    End If
    Recursive FolderPath
    k = Range(Application.Caller.Address).Rows.Count
    If k < UBound(temp, 2) Then
        MsgBox "There are more rows, extend user defined function"
    Else
        For i = UBound(temp, 2) To k
              ReDim Preserve temp(UBound(temp, 1), i)
                temp(0, i) = ""
                temp(1, i) = ""
                temp(2, i) = ""
        Next i
    End If
    ListFiles = Application.Transpose(temp)
    ReDim temp(0)

Sub-main（）
Dim fm为长，sFM为字符串，vFMs为变体，sMASK为字符串
Dim fn作为变体，dFNs作为新脚本。字典
sFM=Environ（“TMP”）和“\QSHWRA\FCS*\FUNCTION\u BLOCK\DR*\*.edf”
如果UBound（Split（sFM，Chr（42））<2，那么退出Sub'，我建议您检查主目录下的所有子文件夹，只收集符合条件的文件。我可能会将WindowsShell与
Dir MainFolder\*.edf/B/S
（设置了裸格式和递归开关）一起使用，只需保存或收集所需子文件夹中的文件即可。但是您也可以对DIR或FileSystemObject和递归执行类似的操作。
您的DIR请求是否解析为
basefolder/X*/*.edf
或等效文件？在
CMD
窗口中，该语法类型无效。通配符似乎只允许出现在路径的最后一段。我不明白。我的路径是这样的，但我在代码中所做的。我给出的基本路由是主目录。例如，在您的第一个代码中，
SecondDir
的值可能是多少？FirstDir的值是
main directory/FSC*
一次一个。SecondDir是
{FirstDir&“/FUNCTION\u BLOCK/”
，通过运行循环，它应该迭代到以“DR”开头的所有目录但循环不起作用。主目录是代码中的
C:\Users\sobiakanwal\Downloads\QSHWRA\QSHWRA\
。因此，如果SecondDir=`Main Directory\FSC*\FUNCTION\u BLOCK`在最后一节之外有通配符，则无效。
