I do not know why after entering the second number for the second time, it always gives the same result

All you have to do is put a breakpoint and watch and see what is happening. You'll have it fixed in no time.

There are two kinds of people in the world: those who can extrapolate from incomplete data.

Hello

i'm trying to make a form to upload an image.
So i combined two events in one just to click only once an upload the file.
But when i click and choose the file, the tmp file is not uploaded.
here's my code, do you have an idea of why? Thank you in advance.

<form target='_self' action='upload.php' method='post' enctype='multipart/form-data'>
        <div class = 'testocentrato'>
        <input style='display:none' type='file' accept='.jpg' name='file' id='file'/>
        <input style='display:none' type='submit' id='caricaimmagine' name='caricaimmagine' />
        <input class='inputfile' type='button' value='Scegli file da PC' onclick='document.getElementById('file').click(); document.getElementById('caricaimmagine').click();' />
        <input style='display:none' type='submit' />
        <input class='inputfile' type='submit'  name='eliminaimmagine' onclick='document.getElementById('eliminaimmagine').click();' value='".$lang['TASTO_ELIMINA_FOTO']."' />
        <input type='hidden' name='id_utente' value='".$user['id']."' />        
        </form></div>

Well, a lot of it has to do with the fact that you're applying a synchronous methodology to an asynchronous construct. Event handlers do not block the main thread, they run in their own context.

That means that the form is being submit before any file is actually chosen.The better route is to use an event handler.

JavaScript

$('#file').change(function(){
   $('#theForm').submit();
});

Then your HTML could look something like:

HTML

<form id="theForm" target='_self' action='upload.php' method='post' enctype='multipart/form-data'>
        <input style='display:none' type='file' accept='.jpg' name='file' id='file'/>
        <input type='hidden' name='id_utente' value='".$user['id']."' /><br />
        <input type='button' value='Scegli file da PC' onClick="$('#file').trigger('click');" /><br />
</form>

HI, ok i understand the 2 asynchronous construct,
but the code you wrote is not working.
Maybe that i need to raise first event to choose the file and then the second event
(the button "upload image") is raised still before the load of image.

the change event is not working, it seems.
Thank you

WCF Service consumed through browser but NOT with WCFClient

I have a strange problem and i'm looking for solution a few days now.

this is my Tools :

my own Webservice Configurator : create webservice with certificate on IIS
my own client (WCF client) which consume this webservice

1.I create the wcf web service with certificate.
2.I run it on browser and show its wsdl (it is ok)
3.I try to open the channel to it but NOT WORKS

Up to now it seems a problem with my WCF Client Smile | :)

BUT no, because when I do the First point (1) on other machine with same tool and try to do the 2 and 3 points , it works fine and the same WCFClient works with the service created on other server (other machine and other iis)

have you an idea about this please ?

Best Regards,

Permissions, firewalls, User Rights Assignments, missing DLLs....

If it works in one place and not in another, it's generally one of two things: configuration or runtime support

The Event Viewer is your friend. You can also drop some debug lines into your client to find your failure point.

As I say the same WCF client works with the same webservice in other machine
But with the one created and hosted (which works on browser !!!! ) in my machine it not works and I have the Exception "EndpointNotFoundException"

Yeah....that's why I suggested that you have an environmental factor. Check the firewall.

SignalR on IIS Not Working

Kevin Marois5-Jan-17 13:08

5-Jan-17 13:08

I have a simple SignalR app that runs fine when self hosted or hosted in VS2015's IIS.

When I attempt to host it in full IIS I don't get very far. Here's my connect code:

public void Connect()
{
    _connection = new HubConnection(ServerUri);

    if (_enableDebugging)  //<== is True for debugging right now
    {
        _connection.TraceLevel = TraceLevels.All;
        _connection.TraceWriter = Console.Out;
    }

    _hubProxy = _connection.CreateHubProxy(HUB_NAME);

    _hubProxy.On<string>("EchoMessage", EchoMessage);
    _hubProxy.On<AssayDashboardInfo>("ResultsAdded", ResultsAdded);
    _hubProxy.On<AssayDashboardInfo>("ResultsChanged", ResultsChanged);

    _connection.Error += _connection_Error;
    _connection.StateChanged += _connection_StateChanged;

    try
    {
        _connection.Start();
    }
    catch (Exception e)
    {
        _logger.Error("*** Connection failed", e);
    }
}

I get no error messages or exceptions. What I DO get is some output in the Console Window:

23:57:41.8538683 - null - ChangeState(Disconnected, Connecting)
23:57:42.0208850 - null - Disconnected
23:57:42.0208850 - null - Transport.Dispose()
23:57:42.0218851 - null - Closed

Again, with no exception or error info I can only assume that it's not finding the hub. The _connection_StateChanged event is called twice - first with "Connecting" then immediately with "Disconnected." And that's as far as I get.

At this point I'm reaching out to see of anyone know what these messages mean or what I'm doing wrong.

Thanks

Just a guess, but it is probably a permissions issue related to the account that is running your Application Pool in IIS. That is the account the code will execute as.

You have to look at the application pool's identity.

If they truly are the same, then I'm not sure where to look next. Event logs?

The app is using the DefaultAppPool, and it's Identity is set to ApplicationPoolIdentity under Build-In Account.

How do I know what account VS's IIS is running under?

Perhaps try an account that is a domain admin account or at least an admin on the machine. Your account that you log onto the machine with might work.

Kevin Marois wrote:

Because it runs under the context of VS, which is loaded as a UI app using your account.

No. That's been a real problem as there are no tutorials that I can find that ACTUALLY show a SignalR service being hosted in IIS. Google and other people point to this which shows how to CREATE an app that runs in IIS, but doesn't actually SHOW you how to host it in IIS.

One thing I did discover is that I was not Awaiting the Connect method nor the _connection.Start. Once I did that I now get an exception:

StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

  Cache-Control: private

}

Which is just as useless as the prior message.

SignalR Error Handling Problem

6-Jan-17 7:34

I've already been through that page. It doesn't really apply as I'm not doing a web app. My client is WPF. I did had the Config item, but everything else doesn't apply.

Thing is, I have this running on my home sever. I just can't get it to run on IIS on my Dev PC here at the office.

Re: SignalR Error Handling Problem

3-Jan-17 12:00

I'm trying to set up error handling in my SignalR app.

This leads me to believe that when I call a method on the server that doesn't exist, I should be able to CATCH an exception for it.

I've done exactly what the example code shows, yet neither the Error event nor the try/catch ever fire:

My Connect method:

public void Connect()
{
    _connection = new HubConnection(ServerUri);
    //TODO: Turn off for production
    _connection.TraceLevel = TraceLevels.All;
    _connection.TraceWriter = Console.Out;
    _hubProxy = _connection.CreateHubProxy("DashboardHub");
    _hubProxy.On<string>("EchoMessage", EchoMessageReceived);
    _hubProxy.On<AssayDashboardInfo>("ResultsAdded", ResultsAdded);
    _hubProxy.On<AssayDashboardInfo>("ResultsChanged", ResultsChanged);
    _connection.Error += ex => Console.WriteLine("ERROR!!!!!!!!: {0}", ex.Message); // <==== NEVER FIRES
    _connection.StateChanged += _connection_StateChanged;
    try
    {
        _connection.Start();
    }
    catch (Exception e)
    {
        throw;  //<==== NEVER FIRES
    }
}

then later I do:

try
{
    // There is no method named NotARealMethod on the server
    _hubProxy.Invoke("NotARealMethod");    
}
catch (Exception e)
{
    throw e;  //<== NEVER FIRES
}

What I DO get is a bunch of text in the Console window which includes

"OnMessage({"I":"0","E"
:"'NotARealMethod' method could not be resolved. No method found with that name.
","T":" at Microsoft.AspNet.SignalR.Hubs.NullMethodDescriptor.<get_invoker>b__

Anyone have an ideas on what's wrong?
