Question

我有一个用python编写的程序，我用pyinstaller转换为exe文件。现在我想通过使用VBA代码调用它在不同的PC上运行它。为了直接从程序中获取输出，我使用了我在互联网上找到的这段代码：

Private Declare Function CreatePipe Lib "kernel32" (phReadPipe As Long, phWritePipe As 

Long, lpPipeAttributes As SECURITY_ATTRIBUTES, ByVal nSize As Long) As Long
Private Declare Function CreateProcess Lib "kernel32" Alias "CreateProcessA" (ByVal lpApplicationName As Long, ByVal lpCommandLine As String, lpProcessAttributes As Any, lpThreadAttributes As Any, ByVal bInheritHandles As Long, ByVal dwCreationFlags As Long, lpEnvironment As Any, ByVal lpCurrentDriectory As String, lpStartupInfo As STARTUPINFO, lpProcessInformation As PROCESS_INFORMATION) As Long
Private Declare Function ReadFile Lib "kernel32" (ByVal hFile As Long, lpBuffer As Any, ByVal nNumberOfBytesToRead As Long, lpNumberOfBytesRead As Long, lpOverlapped As Any) As Long
Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Declare Function WaitForSingleObject Lib "kernel32" (ByVal hHandle As Long, ByVal dwMilliseconds As Long) As Long
Private Declare Function GetExitCodeProcess Lib "kernel32" (ByVal hProcess As Long, lpExitCode As Long) As Long
Private Declare Sub GetStartupInfo Lib "kernel32" Alias "GetStartupInfoA" (lpStartupInfo As STARTUPINFO)
Private Declare Function GetFileSize Lib "kernel32" (ByVal hFile As Long, lpFileSizeHigh As Long) As Long

Public Function Redirect(szBinaryPath As String, szCommandLn As String) As String

Dim tSA_CreatePipe              As SECURITY_ATTRIBUTES
Dim tSA_CreateProcessPrc        As SECURITY_ATTRIBUTES
Dim tSA_CreateProcessThrd       As SECURITY_ATTRIBUTES
Dim tSA_CreateProcessPrcInfo    As PROCESS_INFORMATION
Dim tStartupInfo                As STARTUPINFO
Dim hRead                       As Long
Dim hWrite                      As Long
Dim bRead                       As Long
Dim abytBuff()                  As Byte
Dim lngResult                   As Long
Dim szFullCommand               As String
Dim lngExitCode                 As Long
Dim lngSizeOf                   As Long

tSA_CreatePipe.nLength = Len(tSA_CreatePipe)
tSA_CreatePipe.lpSecurityDescriptor = 0&
tSA_CreatePipe.bInheritHandle = True

tSA_CreateProcessPrc.nLength = Len(tSA_CreateProcessPrc)
tSA_CreateProcessThrd.nLength = Len(tSA_CreateProcessThrd)

If (CreatePipe(hRead, hWrite, tSA_CreatePipe, 0&) <> 0&) Then
    tStartupInfo.cb = Len(tStartupInfo)
    GetStartupInfo tStartupInfo

    With tStartupInfo
        .hStdOutput = hWrite
        .hStdError = hWrite
        .dwFlags = STARTF_USESHOWWINDOW Or STARTF_USESTDHANDLES
        .wShowWindow = SW_HIDE
    End With

    szFullCommand = """" & szBinaryPath & """" & " " & szCommandLn

    Debug.Print szFullCommand

    lngResult = CreateProcess(0&, szFullCommand, tSA_CreateProcessPrc, tSA_CreateProcessThrd, True, 0&, 0&, vbNullString, tStartupInfo, tSA_CreateProcessPrcInfo)

    If (lngResult <> 0&) Then
        lngResult = WaitForSingleObject(tSA_CreateProcessPrcInfo.hProcess, WAIT_INFINITE)
        lngSizeOf = GetFileSize(hRead, 0&)
        If (lngSizeOf > 0) Then
            ReDim abytBuff(lngSizeOf - 1)
            If ReadFile(hRead, abytBuff(0), UBound(abytBuff) + 1, bRead, ByVal 0&) Then
                Redirect = StrConv(abytBuff, vbUnicode)
            End If
        End If
        Call GetExitCodeProcess(tSA_CreateProcessPrcInfo.hProcess, lngExitCode)
        CloseHandle tSA_CreateProcessPrcInfo.hThread
        CloseHandle tSA_CreateProcessPrcInfo.hProcess

        'If (lngExitCode <> 0&) Then Err.Raise vbObject + 1235&, "GetExitCodeProcess", "Non-zero Application exit code " & lngExitCode

        CloseHandle hWrite
        CloseHandle hRead
    Else
        Err.Raise vbObject + 1236&, "CreateProcess", "CreateProcess Failed, Code: " & Err.LastDllError
    End If
End If
End Function

但每当我用

打电话时

output = Redirect("[path to my program.exe]", arguments)

我收到错误：

Error loading Python DLL: [program path]\python26.dll (error code 14003)

当我直接从windows cmd调用它时，该程序运行良好。我还检查了program.exe.manifest的c ++运行时依赖项，所有都在那里。很抱歉这段代码很长，但我觉得包含它是件好事。

感谢您的帮助。

要运行使用python创建的程序，您需要使用相同版本的python来创建安装在该PC中的程序。就像使用visual studio创建的程序需要可再发行以便工作一样，python也是如此。你可以在官方网站上找到python 2.6：https://www.python.org/download/releases/2.6/

加载python26.dll发生错误（14003）
