转载两篇方法，一个是Win7,一个是WinXP, 如果哪位实验了Vista 和 Win8,请告知结果~ XP: HKEY hkRoot,hSubKey; //定义注册表根关键字及子关键字 char ValueName[256]; unsigned char DataValue[256]; unsigned long cbValueName=256; unsigned long cbDataValue=256; char ShellChar[256]; //定义命令行 DWORD dwType; //打开注册表根关键字 if(RegOpenKey(HKEY_CLASSES_ROOT,NULL,&hkRoot)==ERROR_SUCCESS) { //打开子关键字 if(RegOpenKeyEx(hkRoot, "htmlfile//shell//open//command", 0, KEY_ALL_ACCESS, &hSubKey)==ERROR_SUCCESS) { //读取注册表，获取默认浏览器的命令行 RegEnumValue(hSubKey, 0, ValueName, &cbValueName, NULL, &dwType, DataValue, &cbDataValue); // 调用参数（主页地址）赋值 strcpy(ShellChar,(char *)DataValue); strcat(ShellChar," www.neaase.net/~xiaohui"); // 启动浏览器 WinExec(ShellChar,SW_SHOW); } else MessageBox("WEB浏览器打开错误！","错误",MB_OK); } else MessageBox("WEB浏览器打开错误！","错误",MB_OK); //关闭注册表 RegCloseKey(hSubKey); RegCloseKey(hkRoot);
Win7: void LaunchDefaultBrowser() { HKEY hDefBrowserPos = NULL; wstring wstrDefBrowserPath = L"iexplore.exe"; WCHAR wszBuffer[MAX_PATH + 1] = {0}; DWORD dwDataSize = sizeof(wszBuffer); if (ERROR_SUCCESS == ::RegGetValueW( HKEY_CURRENT_USER, L"Software\Microsoft\Windows\Shell\Associations\UrlAssociations\Ftp\UserChoice\", L"Progid", RRF_RT_REG_SZ, 0, wszBuffer, &dwDataSize )) { wstring wstrDefBrowserPos = wszBuffer; wstrDefBrowserPos += L"\shell\open\command\"; dwDataSize = sizeof(wszBuffer); if (ERROR_SUCCESS == ::RegGetValueW( HKEY_CLASSES_ROOT, wstrDefBrowserPos.c_str(), NULL, RRF_RT_REG_SZ, 0, wszBuffer, &dwDataSize )) { // 解出exe 路径. wstrDefBrowserPath = wszBuffer; wstring::size_type leftQuotation = wstrDefBrowserPath.find(L'"'); if (leftQuotation != wstring::npos) { wstring::size_type rightQuotation = wstrDefBrowserPath.find(L'"', leftQuotation + 1); if (rightQuotation != wstring::npos) { wstrDefBrowserPath.assign( wstrDefBrowserPath.begin() + leftQuotation + 1, wstrDefBrowserPath.begin() + rightQuotation ); } } } } ::ShellExecuteW( NULL, L"open", wstrDefBrowserPath.c_str(), NULL, NULL, SW_NORMAL); }
