dll - VB6 .dll 获取调用应用程序路径

Question

我正在从 VB6 制作一个 .dll。我需要知道将使用该 .dll 的应用程序的路径，但我不知道如何直接从 .dll 执行此操作。有人知道该怎么做吗？

提前致谢

好吧，这似乎可以用作 DLL:

Option Explicit

Private Const API_NULL As Long = 0

Private Declare Function GetCurrentProcess Lib "kernel32" () As Long

Private Declare Function GetModuleHandle Lib "kernel32" _
    Alias "GetModuleHandleA" ( _
    ByVal lpModuleName As Long) As Long

Private Declare Function GetModuleBaseName Lib "psapi" _
    Alias "GetModuleBaseNameA" ( _
    ByVal hProcess As Long, _
    ByVal hModule As Long, _
    ByVal BaseName As String, _
    ByVal nSize As Long) As Long

Private Declare Function GetModuleFileNameEx Lib "psapi" _
    Alias "GetModuleFileNameExA" ( _
    ByVal hProcess As Long, _
    ByVal hModule As Long, _
    ByVal FileName As String, _
    ByVal nSize As Long) As Long

Public Function ExeBaseName() As String
    Dim Size As Long

    ExeBaseName = Space$(256)
    Size = GetModuleBaseName(GetCurrentProcess(), _
                             GetModuleHandle(API_NULL), _
                             ExeBaseName, _
                             256)
    ExeBaseName = Left$(ExeBaseName, Size)
End Function

Public Function ExeFileName() As String
    Dim Size As Long

    ExeFileName = Space$(256)
    Size = GetModuleFileNameEx(GetCurrentProcess(), _
                               GetModuleHandle(API_NULL), _
                               ExeFileName, _
                               256)
    ExeFileName = Left$(ExeFileName, Size)
End Function

调用适当的方法获取主程序的基本名称或完整文件名。
