Answer 1

接分！ 注册表，HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class
下面依此读取所有的项，直到找到Class键的值为Display（显卡）或MEDIA（声卡），也可通过专有的函数！
 
以下代码获取显卡（前提是你装了Directx9.0):   
                            D3DDISPLAYMODE   primaryDesktopDisplayMode;   
          m_pD3D->GetAdapterDisplayMode(0,   &primaryDesktopDisplayMode);   
    
          D3DAdapterInfo*   pBestAdapterInfo   =   NULL;   
          D3DDeviceInfo*   pBestDeviceInfo   =   NULL;   
          D3DDeviceCombo*   pBestDeviceCombo   =   NULL;   
    
          for(   UINT   iai   =   0;   iai   <   m_d3dEnumeration.m_pAdapterInfoList->Count();   iai++   )   
          {   
                  D3DAdapterInfo*   pAdapterInfo   =   (D3DAdapterInfo*)m_d3dEnumeration.m_pAdapterInfoList->GetPtr(iai);   
                  for(   UINT   idi   =   0;   idi   <   pAdapterInfo->pDeviceInfoList->Count();   idi++   )   
                  {   
                          D3DDeviceInfo*   pDeviceInfo   =   (D3DDeviceInfo*)pAdapterInfo->pDeviceInfoList->GetPtr(idi);   
                          if   (bRequireHAL   &&   pDeviceInfo->DevType   !=   D3DDEVTYPE_HAL)   
                                  continue;   
                          if   (bRequireREF   &&   pDeviceInfo->DevType   !=   D3DDEVTYPE_REF)   
                                  continue;   
                          for(   UINT   idc   =   0;   idc   <   pDeviceInfo->pDeviceComboList->Count();   idc++   )   
                          {   
                                  D3DDeviceCombo*   pDeviceCombo   =   (D3DDeviceCombo*)pDeviceInfo->pDeviceComboList->GetPtr(idc);   
                                  bool   bAdapterMatchesBB   =   (pDeviceCombo->BackBufferFormat   ==   pDeviceCombo->AdapterFormat);   
                                  if   (!pDeviceCombo->IsWindowed)   
                                          continue;   
                                  if   (pDeviceCombo->AdapterFormat   !=   primaryDesktopDisplayMode.Format)   
                                          continue;   
                                  //   If   we   haven't   found   a   compatible   DeviceCombo   yet,   or   if   this   set   
                                  //   is   better   (because   it's   a   HAL,   and/or   because   formats   match   better),   
                                  //   save   it   
                                  if(   pBestDeviceCombo   ==   NULL   ||     
                                          pBestDeviceCombo->DevType   !=   D3DDEVTYPE_HAL   &&   pDeviceCombo->DevType   ==   D3DDEVTYPE_HAL   ||   
                                          pDeviceCombo->DevType   ==   D3DDEVTYPE_HAL   &&   bAdapterMatchesBB   )   
                                  {   
                                          pBestAdapterInfo   =   pAdapterInfo;   
                                          pBestDeviceInfo   =   pDeviceInfo;   
                                          pBestDeviceCombo   =   pDeviceCombo;   
                                          if(   pDeviceCombo->DevType   ==   D3DDEVTYPE_HAL   &&   bAdapterMatchesBB   )   
                                          {   
                                                  //   This   windowed   device   combo   looks   great   --   take   it   
                                                  goto   EndWindowedDeviceComboSearch;   
                                          }   
                                          //   Otherwise   keep   looking   for   a   better   windowed   device   combo   
                                  }   
                          }   
                  }   
  以上是主要代码，不过不是全部代码（太长了），建议你装上DX9，打开VC生成向导，选DX9APPWIZARD，看一下初始过程。

好象只能获取一般的信息吧，不光是显卡和声卡，还包括其它的硬件，那该怎么实现呢，用SETUPAPI能获取吗
