I've started programming my own telegram-bot in cpp with tgbot-cpp and I've done the code for the ban. When the code checks if the user has the power to ban, it finds the needed power for admins, but not for the owner of the group. I looked in the documentation if there was a way to find the owner of the group, but I couldn't find it. This is the code section that checks the power.
/* Checks if the client has the permission to ban */
bool hasPermission = false;
for (unsigned i = 0; i < admins.size(); i++) {
if (admins[i]->user->id == message->from->id) {
printf("Admin username: %s\n", admins[i]->user->username.c_str());
printf("Can Restrict: %d\n", admins[i]->canRestrictMembers);
if (admins[i]->canRestrictMembers) {
hasPermission = true;
}
break;
}
}
if (!hasPermission) {
return;
}
When an admin uses the ban command, I get a Can Restrict: 1 in the console, but when the owner uses the command I get a Can Restrict: 0.
Is there a reason why the bot doesn't see the owner's power? Is there a way to look for the owner?
After looking better in the documentations, there is a value status for ChatMember that is setted to creator for the owner of the group. That seems to be the way for checking if someone is the owner or not, avoiding the permission issue

I'm trying to convert an existing Alexa app to Google Actions wherein I need to implement session and persistent data values. My understanding from https://developers.google.com/assistant/conversational/df-asdk/save-data is that conv.data and conv.user.storage are intended for this purpose. However, making any attempt to assign values to either results in the error "Error: Unauthorized, Your client does not have permission to the requested URL", and also a reference to the offending key which points to this in the firebase console log: https://us-central1-hello-world-e37ec.cloudfunctions.net/cf-p7ROQlBMjQId9Cws6XdJBA-name. Similar issues here in stackoverflow seem to indicate that I need to grant the appropriate function to all users, but I don't know which function is being called. I'm new to Google Actions, so apologies if I'm overlooking something obvious. Code is very similar to the example offered on google's doc.
const {conversation} = require('#assistant/conversation');
const functions = require('firebase-functions');
const app = conversation();
...
app.handle('status', async conv => {
conv.overwrite = false;
if (conv.user.verificationStatus === 'VERIFIED') {
conv.user.storage = {};
conv.user.storage.sum = 69;
conv.add(`Alright, I'll store that for next time. See you then.`);
} else {
conv.add(`I can't save that right now, but we can add ` +
`new numbers next time!`);
}
});
I found the answer for this issue. Appears that I was not in the correct area of documentation for the "conversation" object/app. Correct method is described here: https://developers.google.com/assistant/conversational/webhooks#read_and_write_storage.
Using my example
app.handle('status', async conv => {
conv.overwrite = false;
if (conv.user.verificationStatus === 'VERIFIED') {
conv.session.params.sum = 69; //within session
conv.user.params.sum = 100; //across sessions
conv.add(`Alright, I'll store that for next time. See you then.`);
} else {
conv.add(`I can't save that right now, but we can add ` +
`new numbers next time!`);
}
});
I am new to C++ and Qt, but I have been playing around with it for a couple of days and I need to come up with a basic prototype of my product by Friday, so there is not much time to convert my 7 years of PHP knowledge into C++ knowledge, as I am sure that it takes a lifetime to master C++. I am getting stuck from time to time in the last couple of days due to non-existing knowledge about the small bits and bytes. At this time I have even no idea what to look for on the Internet.
First of all, I am using Qt as my framework to do a simple GUI network client that can talk to my PHP application. I wanted to create a very simple WebAPI class in this application and have the class "webapi". The scenario is very simple, the user starts the application and the applications checks if the user is logged in or not. If not, then it opens up a login dialog. After entering the information (username / password) into the dialog the user object is filled and the method "authenticate" is called.
The authenticate method then calls the fUser method in the webapi class to make a request to the server holding some information to authenticate the user against the server's database.
In code it looks like this:
Savor.cpp:
user = new User();
while ( user->isLoggedIn() != true )
{
LoginDialog loginWindow;
loginWindow.setModal(true);
int result = loginWindow.exec();
if ( result == QDialog::Accepted )
{
user->authenticate(loginWindow.getUsername(), loginWindow.getPassword());
if ( !user->isLoggedIn() )
{
loginWindow.setUsername(loginWindow.getUsername());
loginWindow.exec();
}
}
else
{
exit(1);//exit with code 1
}
}
User.cpp:
void User::authenticate(QString username, QString password)
{
qDebug() << username;
qDebug() << password;
if ( username != "" && password != "")
{
webapi wapi;
loggedIn = wapi.fUser(this);
}
else
{
loggedIn = false;
}
}
webapi.cpp:
/**
Represents the fUser method on the server,
it wants to get a user object
the user will need to be authenticated with this
then all infos about user are transfered (RSA Keypair etc)
* #brief webapi::fUser
* #param username
* #param password
* #return User
*/
bool webapi::fUser(User baseUser)
{
return true;
}
Now you can clearly see that I am not doing anything at the moment in the webapi::fUser method. In fact, I am not even returning what I would like to return. Instead of a boolean I would like to return a User object, actually the same that I got in the first place through the parameter. However, i get a copy constructor error when I do that. (In my savor.h file I have declared a private attribute as a pointer => User *user;)
So the question is, what am I doing wrong when I call the fUser method? Why can I not simply pass the user object itself to the method ? I have not got around to fully understand const, and pointers and when to use what.
With Qt creator I actually use the MS Visual C++ compiler which throws the error as in the title:
C2664 'webapi::fUser' : cannot convert paramter 1 from 'User *const' to 'User'
I have read http://msdn.microsoft.com/en-us/library/s5b150wd(v=vs.71).aspx this page explaining when this happens, the only solutions is the conversion of the object itself.
If thats the case I might approach the entire problem in the wrong way.
I am looking forward to your tips and help on this matter.
Thank you very much.
webapi::fuser takes a User by value, but you are passing it a User* here:
wapi.fUser(this);
Either pass a User:
wapi.fUser(*this);
or change webapi to take a pointer to User.
Im building a prestashop catalog, but it needs to be visible to logged in customers only. Is this possible. It would be nice if the built in prestashop login is used for this.. any help is appreciated.
I have a suggestion. You can use the Customer Groups feature in PrestaShop 1.5 and only allow logged in customers to see the prices. For every Customer that is grouped in Visitor, they would see your website in Catalog Mode.
Prestashop 1.5 solution:
Simply upload the original file:
classes\controller\FrontController.php
into:
override/classes/controller/FrontController.php
Next, rename the class. Final code should look like this:
class FrontController extends FrontControllerCore
{
public function init()
{
parent::init();
if (!$this->context->customer->isLogged() && $this->php_self != 'authentication' && $this->php_self != 'password')
{
Tools::redirect('index.php?controller=authentication?back=my-account');
}
}
}
The last step is to manually delete the following file so prestashop is aware of the overriden class (It will be re-generated automatically):
cache/class_index.php
And voilà, functionality achieved without overwriting core files.
It'll be easy.
Use this code:
if(!self::$cookie->isLogged(true) AND in_array($this->step, array(1, 2, 3)))
Tools::redirect('authentication.php');
In the preprocess of your indexController
Here’s my solution, it works like a charm and is a very easy fix!
In classes\Configuration.php (around line 114) it looks like this
static public function get($key, $id_lang = NULL)
{
if ($id_lang AND isset(self::$_CONF_LANG[(int)$id_lang][$key]))
return self::$_CONF_LANG[(int)$id_lang][$key];
elseif (is_array(self::$_CONF) AND key_exists($key, self::$_CONF))
return self::$_CONF[$key];
return false;
}
change it to this:
static public function get($key, $id_lang = NULL)
{
//Grab access to the $cookie which is already loaded in the FrontController as global $cookie;
global $cookie;
if ($id_lang AND isset(self::$_CONF_LANG[(int)$id_lang][$key]))
return self::$_CONF_LANG[(int)$id_lang][$key];
elseif (is_array(self::$_CONF) AND key_exists($key, self::$_CONF))
//If the system is trying to find out if Catalog Mode is ON, then return the configuration setting,
//but override it with the user logon status
if($key == 'PS_CATALOG_MODE')
{
return !$cookie->logged || self::$_CONF[$key];
}
else
{
return self::$_CONF[$key];
}
return false;
}
Essentially, I wanted to force the system to display the “Catalog Mode” when the user is not logged in, and to turn this off when he is logged in.
I can guarantee this works for v1.4.3.0 and the code for the current version 1.4.8.2 (at the time of this post) has not changed, so it should work there.
I installed and configured the Poll Module to work fine. The website I am working on will have a Poll instance on a page either as a left rail or a right rail item. The Polls would be setup in a separate folder. On the page item there will be a multilist field which will point to the Polls folder and the user can select whichever poll they choose to. The folder will also contain different sublayouts which will could be selected to be displayed on the rail. I have some custom code which will look at the above mentioned multilist field and show these rail items.
I don't know how to display a Poll programmatically. I haven't found any code samples and also not sure where to set the sublayout. Should I set it on the Poll template itself and then let use code to display it? How can I achieve this in code? Any code samples would be helpful.
Hoping that you will this time accept the answer, I wrote the following for you (based on the OMS Poll module:
Read out the field on your item:
Sitecore.Data.Fields.ReferenceField selectedPoll = (Sitecore.Data.Fields.ReferenceField)Sitecore.Context.Item.Fields["Poll"];
Get the pollItem:
if (selectedPoll.TargetItem != null)
{
Item pollItem = selectedPoll.TargetItem;
if (pollItem != null)
{
Check if the poll is opened or closed and place:
Sitecore.Data.Fields.CheckboxField pollClosed = (Sitecore.Data.Fields.CheckboxField)pollItem.Fields["Closed"];
if (pollClosed.Checked == false)
{
// Set the header of the snippetBlock
ltPollHeader.Text = pollItem.Name;
PollVotingSublayout pollSublayout = (PollVotingSublayout)LoadControl("/sitecore modules/Shell/Poll Module/Controls/PollVotingSublayout.ascx");
pollSublayout.Attributes.Add("sc_parameters", "PollPath=" + pollItem.Paths.FullPath);
pollSublayout.CurrentPoll = (PollItem)pollItem;
this.pollRegion.Controls.Add(pollSublayout);
phPollSnippet.Visible = true;
int blockPos = 0;
if (snippetField != null)
{
if (snippetField.GetItems().Any())
{
blockPos = 1;
}
}
string cssClass = String.Empty;
if (blockPos == 0)
{
cssClass = "snippetColHomeFirst";
}
this.SetClass("snippetColHome", cssClass);
}
Hope that you can make up something using this snippets. Good luck!
There should be a user account called "poll" on the sitecore domain. This account is normally used internal by the poll. In the comment of this account is stated: "Please do not remove this account". the account should have the Sitecore Minimal Page Editor role. I don't know the poll user credentials, but you might find that by either using reflector or opening cs files that you can get by downloading the source.
I want to get the process's user name and check if it is a local administrator . Or check directly if the current procees user is a local administrator
Get the current username with GetUserName(), then call NetUserGetInfo() with the server name (NULL for local) and username you just got. Pass it a USER_INFO_1 structure, and then access usri1_priv in the structure. If the value is USER_PRIV_ADMIN, then you'll know that the username is an admin.
Tested on Windows XP SP3, Windows 7 32 bit and 64 bit with admin user and non-admin user.
Code ported from equivalent C# and uses ATL windows security wrapper classes.
#include <atlbase.h>
#include <atlsecurity.h>
// The function returns true if the user who is running the
// application is a member of the Administrators group,
// which does not necessarily mean the process has admin privileges.
bool IsAdministrator(HRESULT &rHr)
{
bool bIsAdmin = false;
try
{
// Open the access token of the current process.
ATL::CAccessToken aToken;
if (!aToken.GetProcessToken(TOKEN_QUERY))
{
throw MAKE_SCODE(SEVERITY_ERROR, FACILITY_WIN32,
::GetLastError());
}
// Query for the access token's group information.
ATL::CTokenGroups groups;
if (!aToken.GetGroups(&groups))
{
throw MAKE_SCODE(SEVERITY_ERROR, FACILITY_WIN32,
::GetLastError());
}
// Iterate through the access token's groups
// looking for a match against the builtin admins group.
ATL::CSid::CSidArray groupSids;
ATL::CAtlArray<DWORD> groupAttribs;
groups.GetSidsAndAttributes(&groupSids, &groupAttribs);
for (UINT i = 0; !bIsAdmin && i < groupSids.GetCount(); ++i)
{
bIsAdmin = groupSids.GetAt(i) == ATL::Sids::Admins();
}
rHr = S_OK;
}
catch (HRESULT hr)
{
rHr = hr;
}
return bIsAdmin;
}
Presuming you're on a Window OS there's a shell function: IsUserAnAdmin
See MSDN article
This article does suggest rolling your own function though, use CheckTokenMembership. There is even a code example to help you along.
