我正在使用以下函数枚举一个 ftp 目录：

Public Sub EnumFiles(hConnect As Long)
Const cstrProcedure = "EnumFiles"
Dim pData As WIN32_FIND_DATA, hFind As Long, lRet As Long
Dim strSubCode As String
Dim sql As String
On Error GoTo HandleError

sql = "INSERT INTO tblIncomingFiles (AvailableFile) Values ('" & pData.cFileName & "')"
'get sub code to search with
strSubCode = GetSubscriberCode
'create a buffer
pData.cFileName = String(MAX_PATH, 0)
'find the first file
hFind = FtpFindFirstFile(hConnect, "*" & strSubCode & "*", pData, 0, 0)
'if there's no file, then exit sub
If hFind = 0 Then Exit Sub
'show the filename
Debug.Print Left(pData.cFileName, InStr(1, pData.cFileName, String(1, 0), vbBinaryCompare) - 1)
CurrentDb.Execute sql
Do
    'create a buffer
    pData.cFileName = String(MAX_PATH, 0)
    'find the next file
    'lRet = FtpFindNextFile(hFind, pData.cFileName)
    'if there's no next file, exit do
    If lRet = 0 Then Exit Do
    'show the filename
    'Me.Print Left(pData.cFileName, InStr(1, pData.cFileName, String(1, 0), vbBinaryCompare) - 1)
    CurrentDb.Execute sql
Loop
'close the search handle


HandleExit:

    Exit Sub

HandleError:
    ErrorHandle Err, Erl(), cstrModule & "." & cstrProcedure
    Resume HandleExit
End Sub

我在这一行中不断收到数据类型不匹配（错误 13）：

hFind = FtpFindFirstFile(hConnect, "*" & strSubCode & "*", pData, 0, 0)

它突出显示了 pData。我已经在函数的顶部将 pData 声明为 WIN32_FIND_DATA，并且 WIN32_FIND_DATA 在此模块中被声明为一个类型。

Public Declare Function FtpFindFirstFile Lib "wininet.dll" Alias "FtpFindFirstFileA" _
(ByVal hFtpSession As Long, ByVal sSearchFile As String, ByVal lpFindFileData As Long,   _
ByVal lFlags As Long, ByVal dwContext As Long) As Long

Private Type WIN32_FIND_DATA
dwFileAttributes As Long
ftCreationTime As FILETIME
ftLastAccessTime As FILETIME
ftLastWriteTime As FILETIME
nFileSizeHigh As Long
nFileSizeLow As Long
dwReserved0 As Long
dwReserved1 As Long
cFileName As String * MAX_PATH
cAlternate As String * 14
End Type

知道为什么我可能会收到该错误吗？

我在这里找到了一个工作示例，我的FtpFindFirstFile声明与您的略有不同。我的是

Private Declare Function FtpFindFirstFile Lib "wininet.dll" Alias "FtpFindFirstFileA" _
(ByVal hFtpSession As Long, ByVal lpszSearchFile As String, lpFindFileData As WIN32_FIND_DATA, _
ByVal dwFlags As Long, ByVal dwContent As Long) As Long
