Question

祝新年快乐。

我目前有一段代码可以读取大多数音频文件（包括wav，mp3，midi ......），但如果路径或文件名中有空格，它就无法使用。

所以我必须恢复我接受它的其他代码，但只读wav文件......

这是用于阅读所有类型音频的代码：

Option Explicit

Private Declare PtrSafe Function mciSendString Lib "winmm.dll" Alias _
   "mciSendStringA" (ByVal lpstrCommand As String, ByVal _
   lpstrReturnString As Any, ByVal uReturnLength As Long, ByVal _
   hwndCallback As Long) As Long

Private sMusicFile As String
Dim Play

Public Sub Sound2(ByVal File$) 

sMusicFile = File    'path has been included. Ex. "C:\3rdMan.mp3

Play = mciSendString("play " & sMusicFile, 0&, 0, 0)
If Play <> 0 Then 'this triggers if can't play the file
    'Play = mciSendString("'play " & sMusicFile & "'", 0&, 0, 0) 'i tried this aproach, but doesn't seem to work
End If

End Sub


Public Sub StopSound(Optional ByVal FullFile$)
Play = mciSendString("close " & sMusicFile, 0&, 0, 0)
End Sub

任何帮助非常感谢，（我不希望与外部播放器弹出窗口一起解决，也不希望我无法停止使用vba）

Answer 1

去老派......想想DOS 例如：
＆＃34; C：\ Way Too Long \ Long Directory \ File.mp3＆＃34;
成为
＆＃34; C：\ WayToo〜1 \帝〜1 \ File.mp3＆＃34;

诀窍是摆脱空格并保持目录和文件名不超过8个字符。要执行此操作，请删除所有空格，然后在前6个字符后截断并添加波形符（〜）加上数字1。我尝试了这种方法，它对我来说很有效
需要注意的一件事是，如果缩短的目录名称中存在歧义（例如＆＃34; \长文件路径\＆＃34;和＆＃34; \长文件路径\＆＃34;和＆＃34; \长文件路径1436 \＆＃34;）然后你需要在波形符号后调整数字（＆＃34; \ LongFi~1 \＆＃34;＆＃34; \ LongFi 〜2 \＆＃34;和＆＃34; \ LongFi~3 \＆＃34;，按照创建目录的顺序）。

因此，可能会调用前一个文件夹＆＃34; FilePa~1＆＃34;并被删除时，一个类似名称＆＃34; FilePa~2＆＃34;被留下。因此，您的文件路径可能不会自动以＆＃34; ~1＆＃34;为后缀。它可能是＆＃34; ~2＆＃34;或更高的东西，取决于有多少类似命名的目录或文件名
我发现令人难以置信的是，35年前发布了dos，VBA程序员仍然不得不处理目录中这个问题的恐龙！

我找到了解决方法，在路径名中更正空格（和（编辑）文件名（使用没有空格的文件副本，丑陋但有效（name as不是一个好的解决方案）：

首次尝试播放声音后，如果失败，我将当前目录更改为声音目录（临时）：

If Play <> 0 Then 

    Dim path$, FileName0$
    path = CurDir

    If InStr(sMusicFile, ":") > 0 Then ChDrive (Left(sMusicFile, 1))
    If InStr(sMusicFile, "\") > 0 Then
        ChDir (Left(sMusicFile, InStrRev(sMusicFile, "\") - 1))
        FileName0 = Mid(sMusicFile, InStrRev(sMusicFile, "\") + 1)
        If InStr(FileName0, " ") > 0 Then
            FileCopy FileName0, Replace(FileName0, " ", "")
            sMusicFile = Left(sMusicFile, InStrRev(sMusicFile, "\")) & Replace(FileName0, " ", "")
            Play = mciSendString("play " & Replace(FileName0, " ", ""), 0&, 0, 0)
        Else
            Play = mciSendString("play " & FileName0, 0&, 0, 0) 
        End If
    Else
        FileName0 = Replace(sMusicFile, " ", "")
        If sMusicFile <> FileName0 Then
            FileCopy sMusicFile, FileName0
            sMusicFile = FileName0
        End If
        Play = mciSendString("play " & sMusicFile, 0&, 0, 0)
    End If

    ChDrive (Left(path, 1))
    ChDir (Left(path, InStrRev(path, "\") - 1))

End If

注意：对于名称中的空格，我还有一个新方法：Filecopy sMusicFile replace(sMusicFile," ","%")然后播放这个新文件

Answer 3

尝试：

Public Sub Sound2(ByVal File$)

If InStr(1, File, " ") > 0 Then File = """" & File & """"

sMusicFile = File

...

如果有空格，这将把路径包装在引号中，这是某些API函数所必需的。

以下解决方案无需复制文件即可运行。

它将您的代码与来自Get full path with Unicode file name的osknows的代码以及上述Jared的想法结合在一起......

Option Explicit

Private Declare PtrSafe Function mciSendString Lib "winmm.dll" Alias _
   "mciSendStringA" (ByVal lpstrCommand As String, ByVal _
   lpstrReturnString As Any, ByVal uReturnLength As Long, ByVal _
   hwndCallback As Long) As Long

Private Declare Function GetShortPathName Lib "kernel32" Alias "GetShortPathNameA" _
    (ByVal lpszLongPath As String, ByVal lpszShortPath As String, ByVal lBuffer As Long) As Long

Private sMusicFile As String
Dim Play, a

Public Sub Sound2(ByVal File$)

sMusicFile = GetShortPath(File)

Play = mciSendString("play " & sMusicFile, 0&, 0, 0)
If Play <> 0 Then 'this triggers if can't play the file
   'Play = mciSendString("'play " & sMusicFile & "'", 0&, 0, 0) 'i tried this aproach, but doesn't seem to work
End If

End Sub


Public Sub StopSound(Optional ByVal FullFile$)
Play = mciSendString("close " & sMusicFile, 0&, 0, 0)
End Sub


Public Function GetShortPath(ByVal strFileName As String) As String
    'KPD-Team 1999
    'URL: [url]http://www.allapi.net/[/url]
    'E-Mail: [email]KPDTeam@Allapi.net[/email]
    Dim lngRes As Long, strPath As String
    'Create a buffer
    strPath = String$(165, 0)
    'retrieve the short pathname
    lngRes = GetShortPathName(strFileName, strPath, 164)
    'remove all unnecessary chr$(0)'s
    GetShortPath = Left$(strPath, lngRes)
End Function
