Wat's so tired:#include <windows.h> #include <stdio.h> BOOL CtrlHandler( DWORD fdwCtrlType ) { switch( fdwCtrlType ) { // Handle the CTRL-C signal. case CTRL_C_EVENT: printf( "Ctrl-C event\n\n" ); Beep( 750, 300 ); return( TRUE ); // CTRL-CLOSE: confirm that the user wants to exit. case CTRL_CLOSE_EVENT: Beep( 600, 200 ); printf( "Ctrl-Close event\n\n" ); return( TRUE ); // Pass other signals to the next handler. case CTRL_BREAK_EVENT: Beep( 900, 200 ); printf( "Ctrl-Break event\n\n" ); return FALSE; case CTRL_LOGOFF_EVENT: Beep( 1000, 200 ); printf( "Ctrl-Logoff event\n\n" ); return FALSE; case CTRL_SHUTDOWN_EVENT: Beep( 750, 500 ); printf( "Ctrl-Shutdown event\n\n" ); return FALSE; default: return FALSE; } } int main( void ) { if( SetConsoleCtrlHandler( (PHANDLER_ROUTINE) CtrlHandler, TRUE ) ) { printf( "\nThe Control Handler is installed.\n" ); printf( "\n -- Now try pressing Ctrl+C or Ctrl+Break, or" ); printf( "\n try logging off or closing the console...\n" ); printf( "\n(...waiting in a loop for events...)\n\n" ); while( 1 ){ } } else { printf( "\nERROR: Could not set control handler"); return 1; } return 0; } https://msdn.microsoft.com/ru-ru/library/windows/desktop/ms685049(v=vs.85).aspx

Fun B was a mistake. NO_DATA_FOUND was not generated. It was:BEGIN id_party = (SELECT id FROM "PARTY" WHERE "PARTY".number_party = _number_party); return id_party; EXCEPTION WHEN NO_DATA_FOUND THEN RAISE exception 'Ошибка'; END; When SELECT does not use the STRICT target, it does not generate an NO_DATA_FOUND or TOO_MANY_ROWS. To obtain these exceptions, the request must be rewritten: BEGIN SELECT id INTO STRICT id_party FROM "PARTY" WHERE "PARTY".number_party = _number_party; return id_party; EXCEPTION WHEN NO_DATA_FOUND THEN RAISE exception 'Ошибка'; END; In order to withdraw the exemption from function A, the following should be indicated:BEGIN id = В(data); EXCEPTION WHEN NO_DATA_FOUND then RAISE exception '%', SQLERRM; END;

No, he won't. Method issue .printStackTrace() It's just gonna take out a list of methods challenges before the error. I mean:Class 1 output.Issue of method 2 from method 1.Mistake in method 2 on line 13.The method is erroneous and provides information on its origin.

The problem is described in the very text of the error: in your copy of Sql Server, there is already an online database with the same name. All databases are connected to a copy of Sql Server on your computer, with no two single-name databases.To find and deactivate secondary databases, I recommend the opening of Sql Server Management Studio. https://www.microsoft.com/en-us/download/details.aspx?id=42299 if it is not yet available, and contact the copy (LocalDb)\v11.0. In the left, unleash the database list, find a database with the same name and in the context menu in the target point, press "please."

Well, maybe it's not the best possible option, but it works exactly as I need.OneController.java@FXML public static ImageView image; @FXML public AnchorPane anchorPane; @FXML public void initialize(URL url, ResourceBundle br) { click(); } void click(){ TwoController contr = new TwoController(); image = new Image(); if(image != null){ Image i = null; Image im = contr.setImage(i); image.setImage(contr.setImage(im)); anchorPane.getChildren().add(image); } } TwoController.java.... public Image setImage(Image img){ Image img = null; i = img; i = new Image(String.valueOf(getClass().getResource("logo.png"))); return img; }

(1) No. If it's an exception, we either catch it at some level or our program goes out. But when we caught him, we can check him with other means. For example, if (exc instanceof IOException) ... But usually in practice, it's rare when you need it.(2) Yeah, whatever it is, it'll throw that exception away or we'll do it. We can do this:try { throw new Exception(); } catch (Exception e) { // Этот код будет выполнятся всегда. } But it's not recommended that, because it's against the ideal of exceptions. If we can process a mistake at the current level (though we're in the current function) we're not throwing an exception, but we're in the process. As a consequence, it is better to use if instead of try - catch, because a large number of processing loads the programme, and exemptions are handled at a very slow pace.By the way, the second paragraph, you could've checked yourself, what was the problem of writing such a code and seeing whether it would fly out or not?

I'd advise you to use the emulsor of genymotion, the difference is great at once, and there's no malfunction. But first download the project, and then turn on the emulator.P.S.: free emulsion. https://www.youtube.com/watch?v=63T-8YRlFmE

The change should be announced if there are plans to use it. If only the fact of interception is important, it is sufficient to indicate only the type. Differences catch(Exception) and empty catch There is a case where there is a need to intercept non-CLS-coordinated exceptions. More detail on this can be read https://msdn.microsoft.com/en-us/library/bb264489.aspx ♪ The reference just shows that there's a point in that code:catch(Exception) { ... } catch { ... }

I just had to turn off the log. Thank you.ws.Log.Output = (LogData data, string path) => { };

I've been working with emails recently, so it's like this. In my big code, only the port line and you don't have a smtp. EnableSsl = true. public static void SendEmail(string email, string text, string subject) { MailAddress from = new MailAddress("aspnet.confirmation@yandex.ru", "ASP.NET Blog"); MailAddress to = new MailAddress(email); MailMessage message = new MailMessage(from, to); message.Subject = subject; message.Body = text; message.IsBodyHtml = true; SmtpClient smtp = new SmtpClient("smtp.yandex.ru", 25); smtp.Credentials = new System.Net.NetworkCredential("aspnet.confirmation@yandex.ru", "yourpassword"); smtp.EnableSsl = true; smtp.Send(message); } Further on SSL SMTP-server Yandex, please read https://habrahabr.ru/post/237899/ ♪

The mistake is, in your class, you're declaring the method defined in your classroom: the name and list of formal parameters coincide, but the value is different. You can't do that.While returnable types of overloaded methods may vary, the type of return is not sufficient to differentiate the two versions of the method. To solve the problem, you may change the name of your method. Or make the list of formal parameters different from the list of formal parameters of the super-class method (in this case, it is not empty).

The exception is corrected as follows:string answer = answ.Remove(answ.IndexOf('\t'), 3); Regex reg = new Regex("|"); if (reg.IsMatch(answer)) { string[] users = answer.Split(new char[] { '|' }); int i = 0; foreach (string user in users) { if (user == "") { return; } string[] data = user.Split(new char[] { ':' }); Temp.topUsers[i] = data[1] + ":" + data[21]; i++; if (data[1] != "") { gtlist.Items.Add((string)data[1]); } } }

Well, I figured out a question without asking. Maybe someone needs it. Added to <bean class="org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver"> <property name="messageConverters"> <array> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> value>text/plain;charset=UTF-8</value> <value>text/html;charset=UTF-8</value> <value>application/json;charset=UTF-8</value> <value>application/x-www-form-urlencoded;charset=UTF-8</value> </list> </property> </bean> ...And the necessary dependence in maven:<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.8.3</version> </dependency>Then I finally got the desired Russian language on the client.

Look. exemptionslike a disguised non-local Goto (longjmp()). That is, if the processing should be interrupted and a small number of algorithm points should be removed (or a new processing phase should be started (or completed carefully)), the deletion of mb is more convenient.In the case of a logical branch of the normal course of IMHO inspection of the flags (return code), i.e. if Better.

When you push Ctrl+C♪ it's a default python ♪ KeyboardInterrupt exception. When input is provided type E |♪ sys.stdin.read() Reading the whole introduction and coming back: you probably can't press. Ctrl+CThat's why, print() and myParser.print_help() performed.If you push. Ctrl+C As long as the code sys.stdin.read()the code jumps in. except KeyboardInterrupt block: All intermediate lines are not implemented, i.e. print() and myParser.print_help() not implemented at all (not earlier, not later).

Design is used to process the exception https://msdn.microsoft.com/en-us/library/0yd65esw.aspx that you used.Word https://msdn.microsoft.com/en-us/library/1ah5wsex.aspx used to generate an exception. That's what's going on in your code:After the block. try There is an exceptional situation, the control is moving the block catchwhere you generate a manually new untreated exception.(Because inside the block catch No further design try♪ It doesn't really need to be in there because writing an exemption processor is stupid.If I understand your purpose correctly, you want to write something like a logger that's going to fold it up in the xml/drive it on the ecran/ send it on the network.Here's an example of an elementary logger, and to modify it further, you can be dissolved. :using System; namespace ConsoleApplication3 { public static class Logger { public static void Log(string message) { Console.WriteLine(message); } public static void Log(Exception ex) { Console.WriteLine(ex.Message); } } class Program { static void Main(string[] args) { try { throw new Exception("pew pew"); } catch (Exception e) { Logger.Log(e); } } } } Well, I think we can find a lot of options for ready-to-read loggers on the Internet, one of which is exactly what you need.

Actually, it's a very complicated and magnificent question! Of course, there's no C++ speech. The whole API kernel is written on pure C.In general terms, the solution can be described as follows:You write a nucleus module that in the initialization section of the module records the interruption processor (linux/interrupt.h);In addition, the module should describe the function of the lower half, which will do all the useful work in the nucleus mode;The interruption function, after being operated from the kernel, collects the necessary information and activates the delayed launch of the lower half function. Then it just ends.Somewhere... You can write a dozen pages of details for each item! Well, for example, read Oleg Cylaric, "Programming Linux Cycle modules."

No. Installation requires the correct connection ip and port♪ If one of them is unfaithful, you can't say why it didn't come to the base. It is not possible to distinguish the following possible errors (in any case, it will simply not be possible to connect with the TCP/IP server):It's not the server.It's the right server, but it's not the port. This is the right server and port, but mysql is not launched.It's the right server and port, but it's closed.

Exempting is a delicate process, and taking std:string to create problems. The thing is, the exception can jump out of std:string, and what are you gonna do then?Remove the use of STL containers and dynamic memory in the processing of exemptions.
