关闭某个进程的声音

wulinqing

我想把我进程声音关闭了[主要是WEBBROWSER发出的声音]（不影响系统声音状态）
在CSDN上看到一个DELPHI的代码：我翻译成VB6的，不过还是不行
VB6代码如下：

1. 
   
2. Sub Mute() '程序静音
   
3.     Dim hDSound As Long
   
4.     Dim pDirectSoundCreate As Long  ': Pointer;
   
5.     Dim lp As Long
   
6.     Dim hWinmm As Long
   
7.     Dim pmidiStreamOpen As Long
   
8.     Dim pwaveOutWrite As Long
   
9.    
   
10.     hDSound = LoadLibrary("DSound.dll") '把当前进程的DX的声音关闭
    
11.     If hDSound > 0 Then
    
12.         pDirectSoundCreate = GetProcAddress(hDSound, "DirectSoundCreate")
    
13.         If pDirectSoundCreate <> 0 Then
    
14.             Call VirtualProtect(pDirectSoundCreate, 3, PAGE_EXECUTE_READWRITE, lp)
    
15.             MoveMemory &HC20C00, pDirectSoundCreate, 3
    
16.             'Move(#$C2#$0C#$00, pDirectSoundCreate^, 3);'估计是这里出问题了，不懂DELPHI这里代表什么意思
    
17.         End If
    
18.     End If
    
19.    
    
20.     hWinmm = LoadLibrary("Winmm.dll")
    
21.     If hWinmm > 0 Then
    
22.         pmidiStreamOpen = GetProcAddress(hWinmm, "midiStreamOpen")
    
23.         If pmidiStreamOpen <> 0 Then
    
24.             Call VirtualProtect(pmidiStreamOpen, 3, PAGE_EXECUTE_READWRITE, lp)
    
25.             MoveMemory &HC20400, pmidiStreamOpen, 3
    
26.             'Move(#$C2#$04#$00, pmidiStreamOpen^, 3);
    
27.         End If
    
28.     End If
    
29.    
    
30.     If hWinmm > 0 Then
    
31.         pwaveOutWrite = GetProcAddress(hWinmm, "waveOutWrite")
    
32.         If pwaveOutWrite <> 0 Then
    
33.             Call VirtualProtect(pwaveOutWrite, 3, PAGE_EXECUTE_READWRITE, lp)
    
34.             MoveMemory &HC20C00, pwaveOutWrite, 3
    
35.             'Move(#$C2#$0C#$00, pwaveOutWrite^, 3);
    
36.         End If
    
37.     End If
    
38. End Sub

以上是我翻译过来的代码!

下面是原贴中的Delphi代码：

1. 
   
2. procedure TForm1.FormCreate(Sender: TObject);
   
3. Var
   
4.   hDSound: Cardinal;
   
5.   pDirectSoundCreate: Pointer;
   
6.   hWinmm: Cardinal;
   
7.   pmidiStreamOpen: Pointer;
   
8.   pwaveOutWrite: Pointer;
   
9.   lp: Cardinal;
   
10. begin
    
11.   hDSound := LoadLibrary('DSound.dll');
    
12.   If hDSound > 0 Then
    
13.     pDirectSoundCreate := GetProcAddress(hDSound, 'DirectSoundCreate');
    
14.   If pDirectSoundCreate <> nil Then
    
15.   begin
    
16.     VirtualProtect(pDirectSoundCreate, 3, PAGE_EXECUTE_READWRITE, lp);
    
17.     Move(#$C2#$0C#$00, pDirectSoundCreate^, 3);
    
18.   end;
    
19.   hWinmm := LoadLibrary('Winmm.dll');
    
20.   If hWinmm > 0 Then
    
21.     pmidiStreamOpen := GetProcAddress(hWinmm, 'midiStreamOpen');
    
22.   If pmidiStreamOpen <> nil Then
    
23.   begin
    
24.     VirtualProtect(pmidiStreamOpen, 3, PAGE_EXECUTE_READWRITE, lp);
    
25.     Move(#$C2#$04#$00, pmidiStreamOpen^, 3);
    
26.   end;
    
27.   If hWinmm > 0 Then
    
28.     pwaveOutWrite := GetProcAddress(hWinmm, 'waveOutWrite');
    
29.   If pwaveOutWrite <> nil Then
    
30.   begin
    
31.     VirtualProtect(pwaveOutWrite, 3, PAGE_EXECUTE_READWRITE, lp);
    
32.     Move(#$C2#$0C#$00, pwaveOutWrite^, 3);
    
33.   end;
    
34. end;

我没装DELPHI所以不知道这个代码是不是用效果..

阿杰

你文件少个 DSound.dll 吧
