如果工作簿文件始终与CSV文件位于同一文件夹中，则可以使用ActiveWorkbook.Path方法设置相对路径.

If the work book file is always located in the same folder as the CSV file you can utilize the ActiveWorkbook.Path method to set a relative path.

假设csv文件名和连接名相同的示例:

Example assuming csv file name and connection name are the same:

Sub refreshMsgConnection()
    Dim csvFileName As String
    csvFileName = "msg_by_weeks.csv"

    Dim filePath As String
    filePath = ActiveWorkbook.path

    Dim conString As String
    conString = "TEXT;" & filePath & "\" & csvFileName

    With ActiveWorkbook.Connections("msg_by_weeks").Ranges.Item(1).QueryTable
        .connection = conString
        .TextFilePlatform = 437
        .TextFileStartRow = 1
        .TextFileParseType = xlDelimited
        .TextFileTextQualifier = xlTextQualifierDoubleQuote
        .TextFileConsecutiveDelimiter = False
        .TextFileTabDelimiter = False
        .TextFileSemicolonDelimiter = False
        .TextFileCommaDelimiter = True
        .TextFileSpaceDelimiter = False
        .TextFileColumnDataTypes = Array(1, 1, 1, 1)
        .TextFileTrailingMinusNumbers = True
        .TextFilePromptOnRefresh = False
        .Refresh BackgroundQuery:=False
    End With
End Sub

您可能必须根据配置使用某些设置，例如定界符等.如果遇到问题，请在以所需格式设置新连接时记录宏，然后将设置复制到此子目录中

You may have to play with some of the settings based on your configuration such as delimiters etc. If you're having trouble, record a macro while you setup a new connection with the desired format and then copy the settings in this sub.

如果找不到该文件，它将弹出一个文件选择框，供用户查找所需文件.

If the file is not found, it will pop up a file selection box for the user to locate the desired file.
