Hi to all VBA programmers,

I have so many excel files in my folder with 20 columns. Now i want to copy copy column B from all these excel files into one single master file because i need only this column from all my excel files in this folder. Now i am using ronde macro Merging a Range from Multiple Workbooks by Column and it is giving error. Here is the code i am using

Rich (BB code):
Sub MergeHorizontally()
    Dim MyPath As String, FilesInPath As String
    Dim MyFiles() As String
    Dim SourceCcount As Long, FNum As Long
    Dim mybook As Workbook, BaseWks As Worksheet
    Dim sourceRange As Range, destrange As Range
    Dim Cnum As Long, CalcMode As Long

    ' Change this to the path\folder location of the files.
    MyPath = "C:\Users\Ron\test"

    ' Add a slash at the end of path if needed.
    If Right(MyPath, 1) <> "\" Then
        MyPath = MyPath & "\"
    End If

    ' If there are no Excel files in the folder, exit.
    FilesInPath = Dir(MyPath & "*.xl*")
    If FilesInPath = "" Then
        MsgBox "No files found"
        Exit Sub
    End If

    ' Fill in the myFiles array with the list of Excel files in 
    ' the search folder.
    FNum = 0
    Do While FilesInPath <> ""
        FNum = FNum + 1
        ReDim Preserve MyFiles(1 To FNum)
        MyFiles(FNum) = FilesInPath
        FilesInPath = Dir()
    Loop

    ' Change the application properties.
    With Application
        CalcMode = .Calculation
        .Calculation = xlCalculationManual
        .ScreenUpdating = False
        .EnableEvents = False
    End With

    ' Add a new workbook with one sheet.
    Set BaseWks = Workbooks.Add(xlWBATWorksheet).Worksheets(1)
    Cnum = 1

    ' Loop through all of the files in the myFiles array.
    If FNum > 0 Then
        For FNum = LBound(MyFiles) To UBound(MyFiles)
            Set mybook = Nothing
            On Error Resume Next
            Set mybook = Workbooks.Open(MyPath & MyFiles(FNum))
            On Error GoTo 0

            If Not mybook Is Nothing Then

                On Error Resume Next
                Set sourceRange = mybook.Worksheets(1).Range("A1:A10")

                If Err.Number > 0 Then
                    Err.Clear
                    Set sourceRange = Nothing
                Else
                    ' If the source range uses all of the rows 
                    ' then skip this file.
                    If sourceRange.Rows.Count >= BaseWks.Rows.Count Then
                        Set sourceRange = Nothing
                    End If
                End If
                On Error GoTo 0

                If Not sourceRange Is Nothing Then

                    SourceCcount = sourceRange.Columns.Count

                    If Cnum + SourceCcount >= BaseWks.Columns.Count Then
                        MsgBox "There are not enough columns in the sheet."
                        BaseWks.Columns.AutoFit
                        mybook.Close savechanges:=False
                        GoTo ExitTheSub
                    Else

                        ' Copy the file name in the first row.
                        With sourceRange
                            BaseWks.Cells(1, Cnum). _
                                    Resize(, .Columns.Count).Value = MyFiles(FNum)
                        End With

                        ' Set the destination range.
                        Set destrange = BaseWks.Cells(2, Cnum)

                        ' Copy the values from the source range 
                        ' to the destination range.
                        With sourceRange
                            Set destrange = destrange. _
                                            Resize(.Rows.Count, .Columns.Count)
                        End With
                        destrange.Value = sourceRange.Value

                        Cnum = Cnum + SourceCcount
                    End If
                End If
                mybook.Close savechanges:=False
            End If

        Next FNum
        BaseWks.Columns.AutoFit
    End If

ExitTheSub:
    'Restore ScreenUpdating, Calculation and EnableEvents
    With Application
        .ScreenUpdating = True
        .EnableEvents = True
        .Calculation = CalcMode
    End With

End Sub
