使用方法，如要注册 ".abc" 类型的文件：

RegisterShellFileType(".abc", "abcfile", "abc文件", "c:/abc/abc.exe", NULL, "c:/abc/abc.exe", 0);

 

代码：

void RegisterShellFileType(
    string ext_name, string type_name, string description,
    string exec, string args, string icon_file, int icon_index)
{
    HKEY hKey;
    char szIndex[32] = {0};

    RegCreateKey(HKEY_CLASSES_ROOT, ext_name.c_str(), &hKey);
    RegSetValue(hKey, "", REG_SZ, type_name.c_str(), type_name.length());
    RegCloseKey(hKey);

    RegCreateKey(HKEY_CLASSES_ROOT, type_name.c_str(), &hKey);
    RegSetValue(hKey, "", REG_SZ, description.c_str(), description.length());
    RegCloseKey(hKey);

    RegCreateKey(HKEY_CLASSES_ROOT, (type_name+"//DefaultIcon").c_str(), &hKey);
    itoa(icon_index, szIndex, 10);
    icon_file = icon_file + "," + szIndex;
    RegSetValue(hKey, "", REG_SZ, icon_file.c_str(), icon_file.length());
    RegCloseKey(hKey);

    RegCreateKey(HKEY_CLASSES_ROOT, (type_name+"//Shell//Open//Command").c_str(), &hKey);
    exec = exec + " " + args + " /"%1/"";
    RegSetValue(hKey, "", REG_SZ, exec.c_str(), exec.length());
    RegCloseKey(hKey);

    //刷新系统图标缓存
    SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_DWORD, NULL, 0);
}
