c# - NHibernate or FluentNHibernate doesn't seem to handle NpgsqlException [Resolved] -

-

I try to connect with both PostgreSQL and SQL Server databases with Fluent NHibernate I think this user is likely to handle a When I run the trial when I run the trial, I receive a message like "NGPsqlException is not a user code" when I use PostgreSQL when I try with SQL Server, then fix SqlException PostgreSQL handles with 

  Try {this.sessionFactory = Fluently.Configure (). To have the connection code in your application, I host name + "; port =" + this.iGreffeDesktop.Port + "; database =" + this.iGreffeDesktop.Database + "; User ID =" + this.iGreffeDesktop.Username + " ; Password = "+ this.iGreffeDesktop.Password +"; "). Mappings (M => M. Fullent Mappings.AdphomasankAfFlt; compacts & gt; ()). Build Sessions ();} Grip (Exception E) {This. Terror = "Connection Error !!!"; }

and try 

  for SQL Server {this.sessionFactory = fluently.Configure (). Database (MsSqlConfiguration.MsSql2005.ConnectionString (@ " Server = "+ This.iGreffeDesktop.Hostname +"; Initial list = "+ this.iGreffeDesktop.Database +"; user = "+ this.iGreffeDesktop.Username +"; password = "+ this.iGreffeDesktop.Password +"; " Show SQL (.) Mappings (M => M. Fullent Mappings.AdformAssankAffplette  Cottages & gt; ()). Build Session ();} Grip (Exception e) {This.error = "Connection Error !!! "}}

I used the NHibernate 2.1.2.4 on Net 3.5 I tried to handle NpgsqlException but the error message still appears whether something in my code is missing or is it a NHibernate bug?

Edit: It seems that there is a small problem originally.I have written a connection form with Visual Studio C # which is running inside the AutoCAD environment. The user enters the connection information inside the form and my script T tries to connect to the database. The purpose of the above code is to try to connect to a database and if not, then gives the error message to the user.

I have tried the code above by changing the "Comptes" class by "ComptesMap" class to see what happened to the NHibernate Comptes mapping class. I found that for the first time I run scripts inside AutoCAD , Then the script connects to any database, even that which does not exist !!! After closing the AutoCAD and reopening it, I run the script again and then I get the NPGXx access on any PostGrace SQL database, even if there is anything !!!

I really have trouble. It suggests an environmental problem. I'm a novice to use NHibernate. I try to connect to the code found on the web. I do not understand that my code What's wrong in

I have the persistence of the object in my script, which is related to this question and which states that Why do I get successful connections for the first time, others are also successful

But I found out how to handle flute NIBNET exception in this article:

I just change my code by: 

  Try ... constructing session to factor both types of databases (fluenNHbernnet.f.fluent configuration option e) {This.error = e.InnerException.Message; }

And now, it shows the user whether the connection has failed or not.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
