Hello! Help me understand the description of the programme structure and type record♪ The thing is, I don't know how to put it into practice, which is a huge minus. Help me look at the example:
Describe the following structure:
Staff
FIO
Date of receipt
with an alternate part of the record:
Student: Middle Bal
Staff member: Personal No.
Other: Comments
Write the procedures for the entry/retraction of the contents of the record.

Internal firebird data storage format is specific to the platform. The base file on x86 will not be valid on x64 and vice versa.You're gonna have to do it for the correct envelope. http://www.firebirdsql.org/manual/gbak.html On x86, and restore on x64. It's just that the database file is downloaded.This is a similar issue in enSO: https://stackoverflow.com/a/9792513/1988244

Attributing it to a variable by reference. This simplifies access and search amount will be greatly reduced.var mi: TMenuItem; begin mi := TMenuItem(fmPrincipal.FindComponent('teste')); if mi <> nil then begin if mi.Visible then ... mi.Enabled:= ... end; end;

As a basis, I would have done this:The pupil gets a file.java with a sword assignment.For this mission, the junit test is ready.The pupil loads the completed assignments into any drone areaThe software checks, raises Docker the java container, connects him through ssl, compils this mission with javac, starts JUnit tests and writes the log.The student receives a processed log.Spring Boot can do this.Docker, in my view, is the best option, because he has all the advantages of a virtual machine not being such. For example, this container may be used: https://hub.docker.com/r/library/java/ If the use of Docker causes problems, you can raise a virtual car with Vagrant, download some Ubuntu from OpenJDK, get onto SSL and do the same thing with the docker.Alternatively, we can try to compil the code directly in the ranks: https://dzone.com/articles/how-to-compile-a-class-at-runtime-with-java-8-and But then you'll have to touch SecurityManager.

It's a literal direct request for "unity face tracking"and the first reference to documentation: https://docs.unity3d.com/Manual/com.unity.xr.arkit-face-tracking.html So what you're looking for is ARKit Face Tracking.

Your function has a parameter. ScanSubFolders who controls whether or not to be searched in the caps. Shut up, search in the caps is on to turn off, give it to the fourth parameter. False:Scaserch(SelectedFolder, '*.txt', ListBox1.Items, False);

In order to create a module, we need to press File-state-NewUnit or File-State-New-Other, and in the open window select the Unit. What's the Delphi version? Something I didn't quite understand: the application couldn't be created or the module? I've always had both. If you're wondering why you have this problem, there may be a few options: a curve may have been set (to complete decommission and reset), a left version may have been caught, maybe your Vinda didn't like it or liked did not like the an (if version 5-7).

For master-detail, no DBGrid1CellClick or anything. It's enough to make a connection once.Q1.sql.text := 'select id, name from groups'; Q2.DataSource := DS1; Q2.sql.text := 'select id, fio from students where group_id = :id'; The link shall be established through DataSource and the parameters in the request. The names of the parameters in the detailed request shall be submitted by the name of the field in the main request, i.e. the main field of id, so the subordinate will have access to the :id.This connection can be established both from the code (see above) and the object inspector's not even written.About writing requests. Never try to set any meanings (except integer may be) by direct modification of the request. Always use the parameters. Your data can and will break your program depending on the introduction.

I can. The point is, you'll never have copies of the basic abstract class. A copy of a specific subsidiary class will be available in which the method is accurately redesigned.This design template, by the way, is called the Shablon Method (Template method): in the basic abstract class, we collect some algorithm from abstract methods. The work of this algorithm will depend on the subsidiaries of specific classes.Example: The TCocktail base class defines the procedure for preparing a cocktail. Sub-grade classes are taking concrete steps in this process.Basic class:type TCocktail = class protected procedure AddFirstIngridient(); virtual; abstract; //Добавление первого ингридиента procedure AddSeconsIngridient(); virtual; abstract; //Добавление второго ингридиента procedure AddDecorations(); virtual; abstract; //Добавление украшений function GetName(): string; virtual; abstract; //Название public procedure Prepare; //Алгоритм приготовления коктейля end; { TCocktail } procedure TCocktail.Prepare; begin writeln('Готовим коктейль ' + GetName()); AddFirstIngridient(); AddSeconsIngridient(); AddDecorations(); writeln('Ваш коктейль готов'); end; First cocktailtype TBloodyMary = class (TCocktail) protected procedure AddFirstIngridient();override; procedure AddSeconsIngridient();override; procedure AddDecorations();override; function GetName(): string;override; end; { TBloodyMary } procedure TBloodyMary.AddDecorations; begin writeln('Добавляем лед'); end; procedure TBloodyMary.AddFirstIngridient; begin writeln('50мл водки'); end; procedure TBloodyMary.AddSeconsIngridient; begin writeln('150мл томатного сока'); end; function TBloodyMary.GetName: string; begin result := 'Кровавая Мэри'; end; Second cocktailtype TIrishCoffee = class (TCocktail) protected procedure AddFirstIngridient();override; procedure AddSeconsIngridient();override; procedure AddDecorations();override; function GetName(): string;override; end; { TBloodyMary } procedure TIrishCoffee.AddDecorations; begin writeln('50 сливки (33%)'); end; procedure TIrishCoffee.AddFirstIngridient; begin writeln('50мл ирландского виски'); end; procedure TIrishCoffee.AddSeconsIngridient; begin writeln('80мл кофе'); end; function TIrishCoffee.GetName: string; begin result := 'Ирландский кофе'; end; Well, the code itself is:var cocktail: TCocktail; begin cocktail := TBloodyMary.Create; cocktail.Prepare; cocktail := TIrishCoffee.Create; cocktail.Prepare; readln; end.

Write everything PC to the mass/ventor/etc and apply https://en.cppreference.com/w/cpp/algorithm/min_element with the relevant comparator, something likemin_element(begin(PCs),end(PCs), [](const PC& a, const PC& b) { return tie(abs(a.yadra-2),a.GHZ) < tie(abs(b.yadra-2),b.GHZ); }); Well, make sure the terator's back, pointing out a two-processary.

A lot of things. Try searching Embarcadero, which has been added. If you need to reduce the size of the completed file, add the following to the project file:programm MyProg; {$IFNDEF DEBUG} {$WEAKLINKRTTI ON} // если вам не нужны новые возможности RTTI! {$RTTI EXPLICIT METHODS([]) FIELDS([]) PROPERTIES([])} // если вам не нужны новые возможности RTTI! {$ENDIF} uses ... Windows; {$IFNDEF DEBUG} {$SetPEFlags IMAGE_FILE_RELOCS_STRIPPED} // Удаление из exe таблицы релокаций. {$SetPEFlags IMAGE_FILE_DEBUG_STRIPPED} // Удаление из ехе Debug информации {$SetPEFlags IMAGE_FILE_LINE_NUMS_STRIPPED} // Удаление из exe информации о номерах строк {$SetPEFlags IMAGE_FILE_LOCAL_SYMS_STRIPPED} // Удаление local symbols {$SetPEFlags IMAGE_FILE_REMOVABLE_RUN_FROM_SWAP} //При запуске exe с компакта, флэшки, других извлекаемых устройств, считать exe в свап и запустить оттуда. Полезно, если нужно запустить программу с компакта, а потом попросить вставить другой... {$SetPEFlags IMAGE_FILE_NET_RUN_FROM_SWAP} // Аналогично предыдущей, только для сетевых дисков {$SetPEFlags IMAGE_FILE_EXECUTABLE_IMAGE} {$ENDIF} File size in configuration Release It's going to decrease significantly.
