关闭某个进程的声音
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：
Sub Mute() '程序静音
Dim hDSound As Long
Dim pDirectSoundCreate As Long': Pointer;
Dim lp As Long
Dim hWinmm As Long
Dim pmidiStreamOpen As Long
Dim pwaveOutWrite As Long
hDSound = LoadLibrary("DSound.dll") '把当前进程的DX的声音关闭
If hDSound > 0 Then
pDirectSoundCreate = GetProcAddress(hDSound, "DirectSoundCreate")
If pDirectSoundCreate <> 0 Then
Call VirtualProtect(pDirectSoundCreate, 3, PAGE_EXECUTE_READWRITE, lp)
MoveMemory &HC20C00, pDirectSoundCreate, 3
'Move(#$C2#$0C#$00, pDirectSoundCreate^, 3);'估计是这里出问题了，不懂DELPHI这里代表什么意思
End If
End If
hWinmm = LoadLibrary("Winmm.dll")
If hWinmm > 0 Then
pmidiStreamOpen = GetProcAddress(hWinmm, "midiStreamOpen")
If pmidiStreamOpen <> 0 Then
Call VirtualProtect(pmidiStreamOpen, 3, PAGE_EXECUTE_READWRITE, lp)
MoveMemory &HC20400, pmidiStreamOpen, 3
'Move(#$C2#$04#$00, pmidiStreamOpen^, 3);
End If
End If
If hWinmm > 0 Then
pwaveOutWrite = GetProcAddress(hWinmm, "waveOutWrite")
If pwaveOutWrite <> 0 Then
Call VirtualProtect(pwaveOutWrite, 3, PAGE_EXECUTE_READWRITE, lp)
MoveMemory &HC20C00, pwaveOutWrite, 3
'Move(#$C2#$0C#$00, pwaveOutWrite^, 3);
End If
End If
End Sub
以上是我翻译过来的代码!
下面是原贴中的Delphi代码：
procedure TForm1.FormCreate(Sender: TObject);
Var
hDSound: Cardinal;
pDirectSoundCreate: Pointer;
hWinmm: Cardinal;
pmidiStreamOpen: Pointer;
pwaveOutWrite: Pointer;
lp: Cardinal;
begin
hDSound := LoadLibrary('DSound.dll');
If hDSound > 0 Then
pDirectSoundCreate := GetProcAddress(hDSound, 'DirectSoundCreate');
If pDirectSoundCreate <> nil Then
begin
VirtualProtect(pDirectSoundCreate, 3, PAGE_EXECUTE_READWRITE, lp);
Move(#$C2#$0C#$00, pDirectSoundCreate^, 3);
end;
hWinmm := LoadLibrary('Winmm.dll');
If hWinmm > 0 Then
pmidiStreamOpen := GetProcAddress(hWinmm, 'midiStreamOpen');
If pmidiStreamOpen <> nil Then
begin
VirtualProtect(pmidiStreamOpen, 3, PAGE_EXECUTE_READWRITE, lp);
Move(#$C2#$04#$00, pmidiStreamOpen^, 3);
end;
If hWinmm > 0 Then
pwaveOutWrite := GetProcAddress(hWinmm, 'waveOutWrite');
If pwaveOutWrite <> nil Then
begin
VirtualProtect(pwaveOutWrite, 3, PAGE_EXECUTE_READWRITE, lp);
Move(#$C2#$0C#$00, pwaveOutWrite^, 3);
end;
end;
我没装DELPHI所以不知道这个代码是不是用效果.. 你文件少个 DSound.dll 吧
