Question

我一直在尝试使用wininet.dll api来搜索ftp网站以查找匹配的文件，但由于某些原因它无法运行。这是我一直在使用的方法。

Private Sub DoStuff()
     Dim hConnection As Long, hOpen As Long, sOrgPath As String, lRes As Long
     Dim scUserAgent$

    scUserAgent$ = "vb wininet"
    hOpen = InternetOpen(scUserAgent, INTERNET_OPEN_TYPE_PRECONFIG, vbNullString, vbNullString, 0)
    hConnection = InternetConnect(hOpen, mServer$, INTERNET_DEFAULT_FTP_PORT, mUserid$, mPassword$, INTERNET_SERVICE_FTP, INTERNET_FLAG_PASSIVE, 0)

    ''//set the current directory to 'root/testdir/testdir2'
    FtpSetCurrentDirectory hConnection, "testdir/testdir2"

    ReDim matchingFiles$(1)
    Call SearchForFiles(hConnection, ".txt", matchingFiles$)


    ''//Close the connections
    InternetCloseHandle hConnection
    InternetCloseHandle hOpen
End Sub

这是SearchForFiles函数

Public Sub SearchForFiles(hConnection As Long, fileExtension$, matchingFiles$())
    Dim pData As WIN32_FIND_DATA, hFind As Long, lRet As Long
    Dim i%

    ReDim matchingFiles$(1)

    i% = 1

    ''//create a buffer
    pData.cFileName = String(MAX_PATH, 0)
    ''//find the first file
    hFind = FtpFindFirstFile(hConnection, "*." + fileExtension$, pData, 0, 0)

    ''//if there is no file, then exit sub

    If hFind = 0 Then Exit Sub
    ''//show the filename

    matchingFiles$(i%) = Left(pData.cFileName, InStr(1, pData.cFileName, String(1, 0), vbBinaryCompare) - 1)

    Do
        i% = i% + 1
        ''//create a buffer
        pData.cFileName = String(MAX_PATH, 0)
        ''//find the next file
        lRet = InternetFindNextFile(hFind, pData)
        ''//if there is no next file, exit do
        If lRet = 0 Then Exit Do
        ''//show the filename
        ReDim Preserve matchingFiles$(UBound(matchingFiles) + 1)
        matchingFiles$(i%) = Left(pData.cFileName, InStr(1, pData.cFileName, String(1, 0), vbBinaryCompare) - 1)

    Loop
    ''//close the search handle
    InternetCloseHandle hFind
End Sub

我不断得到的只是“。”和“..”用于从SearchForFiles函数返回的文件。我做错了吗？

谢谢！

".txt"例程fileExtension$ SearchForFiles "*." "*..txt" {{1}} {{1}} {{1}} {{1}}也许这会困扰你的计划？我不知道为什么“。”使用这种模式可以找到“......”，但是......
