访问特定文件的代码，但用户的机器已设置

Question

这是我面临的问题。

通常情况下，用户的机器会设置一个记录在C:\Users\User name\Signature 文件夹下的用户图形签名文件，作为在某些Excel 进程中使用它的安全位置。但并非所有用户的签名文件都可以使用，因为以下代码并不总是正确报告文件夹路径。由于配置文件重建，我有一些用户在C:\Users\ 文件夹下的机器设置有两个不同的配置文件 - 在查看 Excel 正在使用的特定图形文件的位置时会引起头痛。我附上了用于搜索正确文件夹的代码示例。

那么，您能否向我提供有关必须设置哪些设置、必须对代码进行哪些更改以确保可靠访问图形文件的信息，但用户的配置文件是在计算机上设置的？

您可以通过Environ()获取它

Function MyDocs() As String
    Dim strStart As String
    Dim strEnd As String

    strStart = Environ("USERPROFILE")
    strEnd = "\Signature\"

    MyDocs = strStart & strEnd
End Function
