桌面及开始菜单快捷方式图标的更新

        基本思路：找到桌面和开始菜单快捷方式文件路径，然后用指定的图标来更新快捷方式的图标即可。注意当前登录的用户是否是管理员，这与快捷方式的路径有直接的关系，找到路径后才能更新图标。

        相关代码如下：

void UpdateFileOperator::UpdateXXXXXXShortcutIcon(){char printInfo[MAX_PRINT_INFO_LEN] = {0};// 获取当前路径TCHAR achModuleName[MAX_PATH] = _T("");CString strCurPath = _T("");GetModuleFileName( AfxGetInstanceHandle(), achModuleName, sizeof (achModuleName) );strCurPath = achModuleName;strCurPath = strCurPath.Left( strCurPath.ReverseFind('\\') + 1 );// 检查图标文件是否存在char szIconPath[MAX_PATH] = {0};sprintf( szIconPath, "%sTrueLink.ico", strCurPath );if ( _taccess( szIconPath, 0 ) != 0 ) // 图标文件不存在{return;}CoInitialize(NULL); BOOL bIsAdmin = FALSE; // 标记当前登录系统的用户是否是管理员if ( IsAdmin() ) // 判断当前登录系统的用户是否是管理员{bIsAdmin = TRUE;}// 更新桌面快捷方式图标    char szDeskShortCutPath[MAX_PATH] = {0};    char szDeskTargetPath[MAX_PATH] = {0};// 当前登录用户是否是管理员与目标路径有直接的关系int nType = 0;if ( bIsAdmin ){nType = CSIDL_COMMON_DESKTOPDIRECTORY;}else{nType = CSIDL_DESKTOP;}BOOL bRet = GetTargetPath( szDeskTargetPath, nType ); // 获取桌面路径if ( !bRet ){return;}sprintf( szDeskShortCutPath, "%s\\桌面快捷方式1.lnk", szDeskTargetPath ); // 对应桌面快捷方式名称if ( _taccess( szDeskShortCutPath, 0 ) == 0 ){UpdateShortcutIcon( szDeskShortCutPath, szIconPath );}else{sprintf( printInfo, "桌面快捷方式路径：%s不存在\r\n", szDeskShortCutPath );_fileLog.WriteData( printInfo, strlen(printInfo) );}    // 更新开始菜单主程序快捷方式图标    char szStartShortCutPath[MAX_PATH] = {0};    char szStartTargetPath[MAX_PATH] = {0};// 当前登录用户是否是管理员与目标路径有直接的关系if ( bIsAdmin ){nType = CSIDL_COMMON_PROGRAMS;}else{nType = CSIDL_PROGRAMS;}bRet = GetTargetPath( szStartTargetPath, nType ); // 获取开始菜单路径if ( !bRet ){return;}sprintf( szStartShortCutPath, "%s\\XXXXXX\\开始菜单快捷方式2.lnk", szStartTargetPath ); // 对应的快捷方式名称if ( _taccess( szStartShortCutPath, 0 ) == 0 ){UpdateShortcutIcon( szStartShortCutPath, szIconPath );}else{sprintf( printInfo, "开始菜单快捷方式路径：%s不存在\r\n", szStartShortCutPath );_fileLog.WriteData( printInfo, strlen(printInfo) );}// 更新开始菜单卸载快捷方式图标    char szUninstallShortCutPath[MAX_PATH] = {0};sprintf( szUninstallShortCutPath, "%s\\XXXXXXX\\tools\\卸载 XXXXXXX.lnk", szStartTargetPath ); // 对应的快捷方式名称if ( _taccess( szUninstallShortCutPath, 0 ) == 0 ){UpdateShortcutIcon( szUninstallShortCutPath, szIconPath );}else{sprintf( printInfo, "开始菜单快捷方式路径：%s不存在\r\n", szUninstallShortCutPath );_fileLog.WriteData( printInfo, strlen(printInfo) );}CoUninitialize(); }// 获取 桌面、开始->程序组 的路径  BOOL UpdateFileOperator::GetTargetPath( char *pszTargetPath, int nFolder ){  if ( pszTargetPath == NULL ){return FALSE;}LPITEMIDLIST  ppidl;  if ( SHGetSpecialFolderLocation( NULL, nFolder, &ppidl ) == S_OK )  {  BOOL flag = SHGetPathFromIDList( ppidl, pszTargetPath );  CoTaskMemFree(ppidl);  return flag;  }  return FALSE;  } BOOL UpdateFileOperator::UpdateShortcutIcon( char* pszShortcutPath, char* pszIconPath ){if ( pszShortcutPath == NULL || pszIconPath == NULL ){return FALSE;} HRESULT hr;  IShellLink     *pLink;  IPersistFile   *ppf; // 创建IShellLink对象  hr = CoCreateInstance( CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER, IID_IShellLink, (void**)&pLink );  if (  FAILED( hr ) )  {return FALSE;}// 从IShellLink对象中获取IPersistFile接口  hr = pLink->QueryInterface( IID_IPersistFile, (void**)&ppf );  if ( FAILED( hr ) )  {  pLink->Release();  return FALSE;  }  WCHAR  wsz[MAX_PATH];  // 使用宽字符wmemset( wsz, 0, MAX_PATH );MultiByteToWideChar( CP_ACP, 0, pszShortcutPath, -1, wsz, MAX_PATH );hr = ppf->Load( wsz, STGM_READ ); // 通过快捷方式文件路径打开快捷方式if (  FAILED( hr ) )  {ppf->Release();pLink->Release();  return FALSE;}hr = pLink->Resolve( NULL, SLR_UPDATE );if (  FAILED( hr ) )  {ppf->Release();pLink->Release();  return FALSE;}hr = pLink->SetIconLocation( pszIconPath, 0 );if (  FAILED( hr ) )  {ppf->Release();pLink->Release();  return FALSE;}ppf->Save(wsz, TRUE);ppf->Release();pLink->Release();  return TRUE;}// 当前登录用户是否具有管理员权限 BOOL UpdateFileOperator::IsAdmin()            {      #define ACCESS_READ         0x01    #define ACCESS_WRITE        0x02HANDLE hToken;  DWORD  dwStatus;  DWORD  dwAccessMask;  DWORD  dwAccessDesired;  DWORD  dwACLSize;  DWORD  dwStructureSize = sizeof(PRIVILEGE_SET);  PACL   pACL = NULL;  PSID   psidAdmin = NULL;  BOOL   bReturn = FALSE;  PRIVILEGE_SET       ps;  GENERIC_MAPPING   GenericMapping;  PSECURITY_DESCRIPTOR           psdAdmin                       =   NULL;  SID_IDENTIFIER_AUTHORITY   SystemSidAuthority   =   SECURITY_NT_AUTHORITY;  //   AccessCheck()   requires   an   impersonation   token.
