I thought I found the solution to my problem when I found this, but it didn't work for me.
When I run in debug mode, my WcfTestClient does not retrieve any data and I receive the error:
A first chance exception of type 'System.NotSupportedException' occurred in System.Data.Entity.dll
The thread '<No Name>' (0x1b50) has exited with code 0 (0x0).
The program '[7040] WCFTestClient.exe: Managed (v4.0.30319)' has exited with code 0 (0x0).....................................
What WILL retrieve data is the following method:
public List<WShortDeal> Test()
{
try
{
return entities.ProductInstance_Deal
.Select(d => new WShortDeal()
{
Id = d.Deal.Id
// ,
// Name = d.Deal.Deal_Language.SingleOrDefault(l => l.Language.Id == 1).Name**
,
NewPrice = (double)d.ProductInstance.Price * (1 - d.Deal.SalesPercentage / 100)
,
OldPrice = (double)d.ProductInstance.Price
,
Valuta = d.ProductInstance.Valuta.ValutaCode
,
Type = d.Deal.Type
,
IdCompanyAccount = d.ProductInstance.IdCompanyAccount
})
.ToList();
}
catch (Exception)
{
return null;
}
}
If I uncomment the two lines that are now commented out, though, I stop receiving data and receive the error message mentioned above in my output window.
Also if I add this line
,ProductCategory = d.ProductInstance.ProductType.ProductCategory.ProductCategory_Language.Where(pcl => pcl.IdLanguage == idLanguage).Single().Name
instead of the line
, Name = d.Deal.Deal_Language.SingleOrDefault(l => l.Language.Id == 1).Name
to my original SELECT-statement, it will also return no data. So I guess maybe it has something to do with all the tables that represent the many-to-many-relationship with my Language-table(??). Because whenever I forget about the join with the "ProductCategory_Language"-table, I can retrieve data again.
Could someone please help? Is there another solution for my problem? I've been struggling with this problem for days now :(
Thanks in advance.
What if the line returns a null before selecting the name?
Try
Name = d.Deal.Deal_Language.Where(l => l.Language.Id == 1)
.Select(s=>s.Name).SingleOrDefault()

It's me again, Van.
Hi everyone,
I hope you're doing well!
I am doing a tutorial on a chat application using Codeigniter 4 with Ajax.
Everything worked fine until I applied the following code in the Model below
public function load_chat_data($sender_id,$receiver_id) {
// $where = ['sender_id' => $sender_id, 'receiver_id' => $receiver_id];
$where1 = "sender_id = $sender_id OR sender_id = $receiver_id";
$where2 = "receiver_id = $receiver_id OR receiver_id = $sender_id";
$builder = $this->db->table('chat_messages');
// $builder->where($where);
$builder->where($where1);
$builder->where($where2);
$builder->orderBy('chat_messages_id','ASC');
$results = $builder->get();
$rows = $results->getResultArray();
if($rows > 0)
{
return $rows;
}
else
{
return false;
}
}
The lines that I commented worked well before they were commented but it was not enough data I wanted to get so I tried to get both data of sender and receiver to display on the view by adding more code. However, when I tried $where1 and $where2 for the WHERE clauses, it didn't work. I think it must be the syntax error. Please correct my codes or any ideas on how the codes work with the same meaning supposed.
Thank you so much!!!
I tried as below, but it still didn't work.
$where1 = "sender_id={$sender_id} OR sender_id={$receiver_id}";
$where2 = "receiver_id={$receiver_id} OR receiver_id={$sender_id}";
Also, I tried:
$where1 = "'sender_id'=$sender_id OR 'sender_id'=$receiver_id";
$where2 = "'receiver_id'=$receiver_id OR 'receiver_id'=$sender_id";
I think you are trying to receive the messages of the conversation between two people. Can you try the following code for this?
$builder->groupStart(); // or $builder->orGroupStart();
$builder->where('sender_id', $sender_id);
$builder->where('receiver_id', $receiver_id);
$builder->groupEnd();
$builder->orGroupStart();
$builder->where('sender_id', $receiver_id);
$builder->where('receiver_id', $sender_id);
$builder->groupEnd();
To start off, here's my main bot.js code (Sorry if it seems like code spaghetti. I'm not the best with javascript):

I'm creating a bot that should be pretty simple:
The bot is a RankBot (at least that's what i dubbed it as), which is supposed to track the amount of wins in battles (since this is for a discord about a fighting game) using a special role that manually increments those wins with a command, then being able to pull up a leaderboard embed showing the people with the most wins. I'm testing it in a discord separate from the one it's for with a friend, and it seemingly worked until we commanded the bot to open the leaderboard. Nothing was shown. We thought it was strange, since it worked before when only one user was in the database, and I went to the PowerShell Command Line to see if there was an error message, and this showed up.
C:\Users\USER\Documents\OF_RankBot\bot.js:89
battleleaderboard.addField(client.users.get(data.user).tag || client.members.get(data.user).tag, `${data.points} Win(s)`);
^
TypeError: Cannot read property 'tag' of undefined
We were confused by what happened, so I removed the tag part of the command and used it again. The embed showed up this time, but it looked like this.
I assumed that what went wrong was that since they both had the same number of wins listed, the part of the bl command that sorts the users was confused. I then went and used bl_add_point on me and tried again. The near exact same embed was shown.
My guess as to what went wrong was that I messed up at some point when setting up the bl_add_point command, but I'm not sure how to fix the issue.
This isn't part of the main problem, but I can't seem to get bl_delete working either. No errors are shown when I use it. In fact, seemingly nothing happens. I'm not sure if these issues are connected, but I really only need the main issue fixed.
Thanks in advance.
edit: I found out partially what happened with the bl_delete issue, which was I simply put the prefix into the case when the prefix was already defined. Now when I put in the command, the PowerShell responds with:
C:\Users\USER\Documents\OF_RankBot\bot.js:72
client.removeScore.run(`${member.guild.id}-${member.id}`)
^
TypeError: Cannot read property 'id' of undefined
Im trying to create an email function that sends a file attached.
I've created the function and added attach() with the route of file I want to attach as follows:
public function newMonthlyBillingRegister(Clinic $clinic, ClinicMonthlyBilling $clinicMonthlyBilling)
{
$countryAdmins = $clinic->findCountryAdmins($clinic->country->id);
$adminEmails = [];
foreach ($countryAdmins as $admin) {
$adminEmails[$admin->email] = $admin->fullName;
}
/** #var BaseMailer $mailer */
$mailer = Yii::$app->mailer;
$mailer->htmlLayout = 'layouts/standard_html';
//$mailer->htmlLayout = 'layouts/invoice_html';
// $mailer->textLayout = 'layouts/invoice_text';
try{
return $mailer
->compose(
['html' => 'newMonthlyBillingRegister-html', 'text' => 'newMonthlyBillingRegister-text'],
[
'clinic' => $clinic,
'clinicMonthlyBilling' => $clinicMonthlyBilling,
]
)
->setFrom([Yii::$app->params['supportEmail'] => Yii::t('app', 'support-email-name', ['appName' => Yii::$app->name])])
->setTo($adminEmails)
->setSubject(Yii::t('app', '[CLINIC][BACKOFFICE] A clinic has upgraded its information in Guarantee Fund Modal.'))
->attach('app/media/uploads/clinic/monthly-billing/'.$clinicMonthlyBilling->trimestralBillingFile)
->queue() && YII_DEBUG && Yii::$app->mailqueue->process();
}
catch(\Exception $e){
LogService::getLogger()->error("Error while sending mail.","EmailService:newMonthlyBillingRegister()",$e->getMessage());
}
}
It gave me an error, but the problem comes when I delete attach() from my code, reverting all my changes on this email function, and when I try to send again the email the following message appears:
PHP Warning: fopen(app/media/uploads/clinic/monthly-billing/user_1_clinic_1_trimestral_billing_file_2019_05_09_08_22_35): failed to open stream: No such file or directory in /app/vendor/swiftmailer/swiftmailer/lib/classes/Swift/ByteStream/FileByteStream.php on line 142
The user_1_clinic_1_trimestral_billing_file_2019_05_09_08_22_35 file doesnt exist in app/media/uploads/clinic/monthly-billing/ folder and even in my database
...what's wrong?¿ I know is in my local but I dont know the reason of trying to search a file that doesn't exist and I didn't code anything to search it,
Anyone can help? Im using PHPStorm,
Thanks a lot for your attention!
I had to clean my email queue and it worked!! Thanks a lot Insane Skull for your help ;)
it is very first time i'm messing with sockets , and read many quotes that this is not for newbies.
so problem is i'm using php smpp library for sending SMS which works fine but after delivering two to three SMS delivery fails with following warning
Warning: stream_socket_sendto() [function.stream-socket-sendto]: An existing connection was forcibly closed by the remote host', and to make it work again i need to restart` apache.
Following is write function which throwing exception
public function write($buf) {
$null = null;
$write = array($this->handle_);
// keep writing until all the data has been written
while (strlen($buf) > 0) {
// wait for stream to become available for writing
$writable = #stream_select($null, $write, $null, $this->sendTimeoutSec_, $this->sendTimeoutUsec_);
if ($writable > 0) {
// write buffer to stream
$written = stream_socket_sendto($this->handle_, $buf);
if ($written === -1 || $written === false) {
throw new TTransportException('TSocket: Could not write '.$written.' bytes '.
$this->host_.':'.$this->port_);
}
// determine how much of the buffer is left to write
$buf = substr($buf, $written);
} else if ($writable === 0) {
throw new TTransportException('TSocket: timed out writing '.strlen($buf).' bytes from '.
$this->host_.':'.$this->port_);
} else {
throw new TTransportException('TSocket: Could not write '.strlen($buf).' bytes '.
$this->host_.':'.$this->port_);
}
}
}
Please anyone can put some light
It was the bug which i won't able to identify/ rectify. then i used an other library from http://www.codeforge.com/read/171085/smpp.php__html and it really saved me.
I am learning to use the Rx extensions for a Silverlight 4 app I am working on. I created a sample app to nail down the process and I cannot get it to return anything.
Here is the main code:
private IObservable<Location> GetGPSCoordinates(string Address1)
{
var gsc = new GeocodeServiceClient("BasicHttpBinding_IGeocodeService") as IGeocodeService;
Location returnLocation = new Location();
GeocodeResponse gcResp = new GeocodeResponse();
GeocodeRequest gcr = new GeocodeRequest();
gcr.Credentials = new Credentials();
gcr.Credentials.ApplicationId = APP_ID2;
gcr.Query = Address1;
var myFunc = Observable.FromAsyncPattern<GeocodeRequest, GeocodeResponse>(gsc.BeginGeocode, gsc.EndGeocode);
gcResp = myFunc(gcr) as GeocodeResponse;
if (gcResp.Results.Count > 0 && gcResp.Results[0].Locations.Count > 0)
{
returnLocation = gcResp.Results[0].Locations[0];
}
return returnLocation as IObservable<Location>;
}
gcResp comes back as null. Any thoughts or suggestions would be greatly appreciated.
The observable source you are subscribing to is asynchronous, so you can't access the result immediately after subscribing. You need to access the result in the subscription.
Better yet, don't subscribe at all and simply compose the response:
private IObservable<Location> GetGPSCoordinates(string Address1)
{
IGeocodeService gsc =
new GeocodeServiceClient("BasicHttpBinding_IGeocodeService");
Location returnLocation = new Location();
GeocodeResponse gcResp = new GeocodeResponse();
GeocodeRequest gcr = new GeocodeRequest();
gcr.Credentials = new Credentials();
gcr.Credentials.ApplicationId = APP_ID2;
gcr.Query = Address1;
var factory = Observable.FromAsyncPattern<GeocodeRequest, GeocodeResponse>(
gsc.BeginGeocode, gsc.EndGeocode);
return factory(gcr)
.Where(response => response.Results.Count > 0 &&
response.Results[0].Locations.Count > 0)
.Select(response => response.Results[0].Locations[0]);
}
If you only need the first valid value (the location of the address is unlikely to change), then add a .Take(1) between the Where and Select.
Edit: If you want to specifically handle the address not being found, you can either return results and have the consumer deal with it or you can return an Exception and provide an OnError handler when subscribing. If you're thinking of doing the latter, you would use SelectMany:
return factory(gcr)
.SelectMany(response => (response.Results.Count > 0 &&
response.Results[0].Locations.Count > 0)
? Observable.Return(response.Results[0].Locations[0])
: Observable.Throw<Location>(new AddressNotFoundException())
);
If you expand out the type of myFunc you'll see that it is Func<GeocodeRequest, IObservable<GeocodeResponse>>.
Func<GeocodeRequest, IObservable<GeocodeResponse>> myFunc =
Observable.FromAsyncPattern<GeocodeRequest, GeocodeResponse>
(gsc.BeginGeocode, gsc.EndGeocode);
So when you call myFunc(gcr) you have an IObservable<GeocodeResponse> and not a GeocodeResponse. Your code myFunc(gcr) as GeocodeResponse returns null because the cast is invalid.
What you need to do is either get the last value of the observable or just do a subscribe. Calling .Last() will block. If you call .Subscribe(...) your response will come thru on the call back thread.
Try this:
gcResp = myFunc(gcr).Last();
Let me know how you go.
Richard (and others),
So I have the code returning the location and I have the calling code subscribing. Here is (hopefully) the final issue. When I call GetGPSCoordinates, the next statement gets executed immediately without waiting for the subscribe to finish. Here's an example in a button OnClick event handler.
Location newLoc = new Location();
GetGPSCoordinates(this.Input.Text).ObserveOnDispatcher().Subscribe(x =>
{
if (x.Results.Count > 0 && x.Results[0].Locations.Count > 0)
{
newLoc = x.Results[0].Locations[0];
Output.Text = "Latitude: " + newLoc.Latitude.ToString() +
", Longtude: " + newLoc.Longitude.ToString();
}
else
{
Output.Text = "Invalid address";
}
});
Output.Text = " Outside of subscribe --- Latitude: " + newLoc.Latitude.ToString() +
", Longtude: " + newLoc.Longitude.ToString();
The Output.Text assignment that takes place outside of Subscribe executes before the Subscribe has finished and displays zeros and then the one inside the subscribe displays the new location info.
The purpose of this process is to get location info that will then be saved in a database record and I am processing multiple addresses sequentially in a Foreach loop. I chose Rx Extensions as a solution to avoid the problem of the async callback as a coding trap. But it seems I have exchanged one trap for another.
Thoughts, comments, suggestions?
