IDEJA: Tač skrin meni u restoranima

 

 

 

Uvek se iznerviram u restoranu zbog konobara koji vas ostavljaju da čekate i čekate i čekate. . . da biste naručili ono što želite. Predlažem da svaki sto u restoranu ima tač srkin meni tako da ne morate da mašete konobaru dok vas ruka ne zaboli, več odaberete i pritisnete ono šta želite a konobar samo treba da vam donese narudžbinu. Da li i Vi imate neku ideju? Izvor: Whynot. net Pripremio: Milenko Kusurović

Istraživanje poboljšanja jezika C# 7.2 i 7.3 za kupce knjige

 

 

 

Namenjeno kupcima knjige C# 7. 1 i . NET Core 2. 0 – Moderno međuplatformsko programiranje - Treće izdanje LINK KA KNJIZI With the C# 7 generation, Microsoft has decided to increase the cadence of language releases, releasing minor version numbers, aka point releases, for the first time since C# 1. 1. This allows new features to be used by programmers faster than ever before, but the policy poses a challenge to writers of books about C#. Introduction One of the hardest parts of writing for technology is deciding when to stop chasing the latest changes and adding new content. Back in March 2017, I was reviewing the final drafts of the second edition of my book, C# 7 and . NET Core – Modern Cross-Platform Development. In Chapter 2, Speaking C# I got to the topic of representing number literals. One of the improvements in C# 7 is the ability to use the underscore character as a digit separator. For example, when writing large numbers in decimal you can improve the readability of number literals using underscores, and you can express binary or hexadecimal number literals by prefixing the number literal with 0b or 0x, as shown in the following code: // C# 6 and earlier int decimalNotation = 2000000; // 2 million // C# 7 and 7. 1 int decimalNotation = 2_000_000; // 2 million int binaryNotation = 0b0001_1110_1000_0100_1000_0000; // 2 million int hexadecimalNotation = 0x001E_8480; // 2 million  But in the final draft I hadn't included code examples of using underscores in number literals. At the last minute, I decided to add the preceding examples to the book. Unfortunately, I assumed that the underscore could be used to separate the prefixes 0b and 0x from the digits, and did not check the code examples would compile until the following day, after the book had gone to print. I had to release an erratum on the book's web page before it even reached the shelves. I felt so embarrassed. In the third edition, C# 7. 1 and . NET Core 2. 0 – Modern Cross-Platform Development, I fixed the code examples by removing the unsupported underscores after the prefixes since they are not supported in C# 7 or C# 7. 1. Ironically, just as the third edition was due to go to print, Microsoft released C# 7. 2, which adds support for using an underscore after the prefixes, as shown in the following code: // C# 7. 2 and later int binaryNotation = 0b_0001_1110_1000_0100_1000_0000; // 2 million int hexadecimalNotation = 0x_001E_8480; // 2 million Gah! Clearly, I wasn't the only programmer who thought it is natural to be able to use underscores after the 0b or 0x prefixes. For the third edition, I decided not to make any last-minute changes to the book. This was partly because I didn't want to risk making a mistake again, and also because the code examples do work, they just don't show the latest improvement. Maybe in the fourth edition I will finally get the whole book perfect! But, of course, in the programming world that's impossible. Since the third edition covers C# 7. 1, I have written this article to cover the improvements in C# 7. 2 that are available today, and to preview the improvements coming early in 2018 with C# 7. 3. Enabling C# 7 point releases Developer tools like Visual Studio 2017, Visual Studio Code, and the dotnet command line interface assume that you want to use the C# 7. 0 language compiler by default. To use the improvements in a C# point release like 7. 1 or 7. 2, you must add a configuration element to the project file, as shown in the following markup: <LangVersion>7. 2</LangVersion> Potential values for the  markup are shown in the following table: LangVersion Description 7, 7. 1, 7. 2, 7. 3, 8 Entering a specific version number will use that compiler if it has been installed. default Uses the highest major number without a minor number, for example, 7 in 2017 and 8 later in 2018. latest Uses the highest major and highest minor number, for example, 7. 2 in 2017, 7. 3 early in 2018, 8 later in 2018. To be able to use C# 7. 2, either install Visual Studio 2017 version 15. 5 on Windows, or install . NET Core SDK 2. 1. 2 on Windows, macOS, or Linux from the following link: https://www. microsoft. com/net/download/ Run the . NET Core SDK installer, as shown in the following screenshot: Setting up a project for exploring C# 7. 2 improvements In Visual Studio 2017 version 15. 5 or later, create a new Console App (. NET Core) project named ExploringCS72 in a solution named Bonus, as shown in the following screenshot: You can download the projects created in this article from the Packt website or from the following GitHub repository: https://github. com/PacktPublishing/CSharp-7. 1-and-. NET-Core-2. 0-Modern-Cross-Platform-Development-Third-Edition/tree/master/BonusSectionCode/Bonus In Visual Studio Code, create a new folder named Bonus with a subfolder named ExploringCS72. Open the ExploringCS72 folder. Navigate to View | Integrated Terminal, and enter the following command: dotnet new console In either Visual Studio 2017 or Visual Studio Code, edit the ExploringCS72. csproj file, and add the  element, as shown highlighted in the following markup: <Project Sdk="Microsoft. NET. Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>netcoreapp2. 0</TargetFramework> <LangVersion>7. 2</LangVersion> </PropertyGroup> </Project> Edit the Program. cs file, as shown in the following code: using static System. Console; namespace ExploringCS72 { class Program { static void Main(string[] args) { int year = 0b_0000_0111_1011_0100; WriteLine($"I was born in {year}. "); } } } In Visual Studio 2017, navigate to Debug | Start Without Debugging, or press Ctrl + F5. In Visual Studio Code, in Integrated Terminal, enter the following command: dotnet run You should see the following output, which confirms that you have successfully enabled C# 7. 2 for this project: I was born in 1972. In Visual Studio Code, note that the C# extension version 1. 13. 1 (released on November 13, 2017) has not been updated to recognize the improvements in C# 7. 2. You will see red squiggle compile errors in the editor even though the code will compile and run without problems, as shown in the following screenshot: Controlling access to type members with modifiers When you define a type like a class with members like fields, you control where those members can be accessed by applying modifiers like public and private. Until C# 7. 2, there have been five combinations access modifier keywords. C# 7. 2 adds a sixth combination, as shown in the last row of the following table: Access modifier Description private Member is accessible inside the type only. This is the default if no keyword is applied to a member. internal Member is accessible inside the type, or any type that is in the same assembly. protected Member is accessible inside the type, or any type that inherits from the type. public Member is accessible everywhere. internal protected Member is accessible inside the type, or any type that is in the same assembly, or any type that inherits from the type. Equivalent to internal_OR_protected. private protected Member is accessible inside the type, or any type that inherits from the type and is in the same assembly. Equivalent to internal_AND_protected. Setting up a . NET Standard class library to explore access modifiers In Visual Studio 2017 version 15. 5 or later, add a new Class Library (. NET Standard) project named ExploringCS72Lib to the current solution, as shown in the following screenshot: In Visual Studio Code, create a new subfolder in the Bonus folder named ExploringCS72Lib. Open the ExploringCS72Lib folder. Navigate to View | Integrated Terminal, and enter the following command: dotnet new classlib Open the Bonus folder so that you can work with both projects. In either Visual Studio 2017 or Visual Studio Code, edit the ExploringCS72Lib. csproj file, and add the  element, as shown highlighted in the following markup: <Project Sdk="Microsoft. NET. Sdk"> <PropertyGroup> <TargetFramework>netstandard2. 0</TargetFramework> <LangVersion>7. 2</LangVersion> </PropertyGroup> </Project> In the class library, rename the class file from Class1 to AccessModifiers, and edit the class, as shown in the following code: using static System. Console; namespace ExploringCS72 { public class AccessModifiers { private int InTypeOnly; internal int InSameAssembly; protected int InDerivedType; internal protected int InSameAssemblyOrDerivedType; private protected int InSameAssemblyAndDerivedType; // C# 7. 2 public int Everywhere; public void ReadFields() { WriteLine("Inside the same type:"); WriteLine(InTypeOnly); WriteLine(InSameAssembly); WriteLine(InDerivedType); WriteLine(InSameAssemblyOrDerivedType); WriteLine(InSameAssemblyAndDerivedType); WriteLine(Everywhere); } } public class DerivedInSameAssembly : AccessModifiers { public void ReadFieldsInDerivedType() { WriteLine("Inside a derived type in same assembly:"); //WriteLine(InTypeOnly); // is not visible WriteLine(InSameAssembly); WriteLine(InDerivedType); WriteLine(InSameAssemblyOrDerivedType); WriteLine(InSameAssemblyAndDerivedType); WriteLine(Everywhere); } } } Edit the ExploringCS72. csproj file, and add the  element to reference the class library in the console app, as shown highlighted in the following markup: <Project Sdk="Microsoft. NET. Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>netcoreapp2. 0</TargetFramework> <LangVersion>7. 2</LangVersion> </PropertyGroup> <ItemGroup> <ProjectReference Include=". . \ExploringCS72Lib\ExploringCS72Lib. csproj" /> </ItemGroup> </Project> Edit the Program. cs file, as shown in the following code: using static System. Console; namespace ExploringCS72 { class Program { static void Main(string[] args) { int year = 0b_0000_0111_1011_0100; WriteLine($"I was born in {year}. "); } public void ReadFieldsInType() { WriteLine("Inside a type in different assembly:"); var am = new AccessModifiers(); WriteLine(am. Everywhere); } } public class DerivedInDifferentAssembly : AccessModifiers { public void ReadFieldsInDerivedType() { WriteLine("Inside a derived type in different assembly:"); WriteLine(InDerivedType); WriteLine(InSameAssemblyOrDerivedType); WriteLine(Everywhere); } } } When entering code that accesses the am variable, note that IntelliSense only shows members that are visible due to access control. Passing parameters to methods In the original C# language, parameters had to be passed in the order that they were declared in the method. In C# 4, Microsoft introduced named parameters so that values could be passed in a custom order and even made optional. But if a developer chose to name parameters, all of them had to be named. In C# 7. 2, you can mix named and unnamed parameters, as long as they are passed in the correct position. In Program. cs, add a static method, as shown in the following code: public static void PassingParameters(string name, int year) { WriteLine($"{name} was born in {year}. "); } In the Main method, add the following statement: PassingParameters(name: "Bob", 1945); Visual Studio Code will show an error, as shown in the following screenshot, but the code will compile and execute. Optimizing performance with value types The fourth and final feature of C# 7. 2 is working with value types while using reference semantics. This can improve performance in very specialized scenarios. You are unlikely to use them much in your own code, unless like Microsoft themselves, you create frameworks for other programmers to build upon that need to do a lot of memory management. You can learn more about these features at the following link: https://docs. microsoft. com/en-gb/dotnet/csharp/reference-semantics-with-value-types Conclusion I plan to refresh this bonus article when C# 7. 3 is released to update it with the new features in that point release. Good luck with all your C# adventures!
 
   

KAKO DA – zaštita dokumenata, Word

 

 

 

MS Word omogućava svojim korisnicima da na više načina zaštite vlastite dokumente. M icrosoft Word vam omogućava da sve svoje radove zaštitite od neovlašćenog pristupa, i to na više načina. Postoje u osnovi dva načina za zaštitu dokumenata: • Zaštita lozinkom za otvaranje dokumenta - Ovim načinom nike neće moći da uopšte otvori dokument u Word-u, tj. otvaranje je moguće samo povlašćenima koji imaju lozinku. Ovde imamo dav tipa lozinke:- Lozinka za samo otvaranje dokumenta(Password to Open) - ovde korisnik pre otvaranja dokumenta dobija dijalog prozor u kome mora da unese lozinku. - Lozinka za izmene u dokumentu(Password to Modify) - ovde postavljate lozinku da bi obezbedili dokument kako bi samo odabrani mogli da prave izmene u zaštićenom dokumentu. Postavljanje lozinke ide tako što izaberete “Tools > Options”, pređete na karticu “Save” u okviru dijalog prozora “Options”. U sekciji “File sharing options for” unesite lozinke dužine do 15 karaktera. Pri unosu pazite na mala i velika slova, pošto je ovo polje Case-sensitive. Kliknite na kraju “OK”, dobićete dijalog prozor “Confirm Password” u kome ćete ponoviti prethodno unetu lozinku (dobićete poruku o grešci ako pogrešite unos drugi put). Kada konačno kliknete OK snimite dokument da bi ste aktivirali lozinku za dati dokument • Zaštita dokumenta davanjem atributa-statusa “Read-Only” - Ovim načinom dati dokument se može učitati u Word, ali samo za čitanje. Bilo kakve izmene nisu dozvoljene. Da bi aktivirali ovu opciju pozovite meni “Tools > Options” i potvrdite poslednje polje za potvrdu “Read Only Recommended”. Na ovaj način će svako ko otvara dotični dokument videti dijalog prozor koji predlaže da se dokument otvori u Read Only režimu. Ako kliknete na Yes, dokument se otvara kao Read Only. Ako izaberete No dokument će se otvoriti kao i svaki dokument. Znači, ova opcija zaštite se svodi na volju korisnika dokumenta kako će ga učitati. Da bi dokument prebacili u potpuni “Read Only” status, pređite u Windows Explorer, klinite na ime dokumenta denim tasterom i izaberite opciju “Properties”. U novom dijalog prozoru potvrdite (chek-irajte) polje za potvrdu “Read-Only”. Na ovaj način neće biti dozvoljene nikakve izmene na dokumentu. Pripremio: Milenko Kusurović
 
   

Veb razvoj na strani klijenta

 

 

 

IZ XIV POGLAVLJA KNJIGE C# 7. 1 I . NET. CORE Kada gradi veb aplikacije, programer treba da zna više, a ne samo jezik C# i . NET Core. Na strani klijenta (odnosno u veb pretraživaču) upotrebićete kombinaciju sledećih komponenata: - HTML5 - Koristi se za sadržaj i strukturu veb stranice. - CSS3 - Koristi se za stilove koji su primenjeni na elemente na veb stranici. - JavaScript - Koristi se za proceduralne akcije veb stranice. Iako su HTML5, CSS3 i JavaScript osnovne komponente čeonog veb razvoja, postoje mnoge biblioteke koje čeoni veb razvoj mogu da učine produktivnijim, uključujući sledeće: - Bootstrap - Ovo je CSS3 biblioteka za implementiranje prilagodljivog dizajna na veb stranice. Opciono, može da koristi jQuery za dodavanje naprednih dinamičkih funkcija. - jQuery - Ovo je popularna JavaScript biblioteka. - TypeScript - Ovo je jezik koji je kreirao „Microsoft“, a prihvatio ga je „Google“; jezik dodaje funkcije tipa jezika C# u JavaScript jezik. TypeScript fajlovi (*. ts) mogu da budu kompajlirani u JavaScript fajlove (*. js) u toku procesa izgradnje. - Angular - Ovo je popularna biblioteka za izgradnju jednostranih aplikacija (SPA) pomoću TypeScripta. - React - Ovo je popularna biblioteka za izgradnju jednostranih aplikacija (SPA). - Redux - Ovo je biblioteka za upravljanje stanjem. Kao deo procesa izgradnje i primene, verovatno ćete upotrebiti kombinaciju ovih tehnologija: - Node. js - Ovo je JavaScript biblioteka na strani servera. - NPM - Ovo je Node Package Manager, koji je postao glavni upravljač paketima za JavaScript i mnoge druge module veb razvoja. - Bower - Ovo je upravljač paketima na strani klijenta za Veb. - Gulp - Ovo je komplet alatki za automatizaciju napornih ili dugotrajnih zadataka. - Webpack - Ovo je popularni softver za pakovanje modula - alatka za kompajliranje, transformisanje i pakovanje izvornog koda aplikacije.

Vreme je za kalendare u obliku prstena

 

 

 

Malo, malo pa je sreda. Eto kao juče je bio oktobar 2007. A, davnog oktobra 1975. sam u Zemunu prošao hotel JUGOSLAVIJU, da bih u jednom od tri solitera ušao u svoju studentsku sobu. Vreme se okreće i na časovniku prstenu. Dani su krugovi koji se najbrže okreću. "Ovaj beskrajni zidni kalendar vas neće samo informisati već će vam pružati i svakodnevno zadovoljstvo dok ga gledate. A, vreme dok ga ne sredite izgleda haotično. Dizajner je Sebastian Bergne. Pogledajte njegove radove. Inspirišite se. Počnite da radite. Svaku vašu ideju ćemo promovisati.
