Learn Ultra-Fast Database App Development With Delphi LiveBindings Sample App

C++ Builder

Connecting to database and data-aware controls was no more a time consuming task for Delphi/C++Builder developers. With Absolute no code you can just and drop components and bind visually to show case your valuable data to the user interface controls faster. BindGridLinkVCL Sample demonstrates the use of a TBindGridLink. You can find Delphi and C++ code samples in GitHub Repositories. Search by name into the samples repositories according to your RAD Studio version. Components used in BindGridLinkVCL App: TStringGrid represents a grid control designed to simplify the handling of strings and associated objects. TBindGridLink: Used when binding controls to grids. TBindGridLink is built on the TCustomBindGridLink class TBindingsList: Built on the TCustomBindingsList component and publishes additional properties that can be accessed from within the Object Inspector. Add a new binding and select TBindGridLink under Quick Bindings. TBindingSourceDB: Nonvisual component that provides a way to make data contained by the specified data source available to all components that want to access it, using LiveBindings. Along with these TDBNavigator, TDataSource,TClientDataset and other UI components such as TLabel, TEdit ,TImage were used. Implementation Details : When you run the application, it shows a string grid with data rows from the connected database. DBNavigator is to navigate among the records in the StringGrid. When you select a record the corresponding fish category and image is populated. Create TBindGridLink Bindings to link the StringGrid Control and TBindSourceDB. Also other bind links such as label, image were made. Set the BindSourceDB’s Dataset with TClientDataset created. Activate the client dataset. Check out the full article in the DocWiki about the BindGridLinkVCL Sample.

Learn How To Embed C Source Code To Delphi FireMonkey Applications

Delphi

In this CodeRage session, you can explore how to embed C code into a Delphi FireMonkey project. The demo was demonstrated by Marion Candau. How to compile C code to embed into Delphi project How to link the C objects to the Delphi units How to call C functions To compile C source code you can go with C++ Builder or other tools for instance Visual Studio. We have 2 options for the resulting format, they are object files and shared libraries. You can use object files for Windows 32 and 64 bits, also macOS 32 and 64 bits. And a shared library for Linux, Android, and iOS. How to link the C objects to the Delphi units? We need to link the C object files for Windows and macOS 32 platforms For mobile platforms, we link each function with its shared library file and need to add the path to the shared library into the Search path. To learn more about how to embed C code on different platforms, be sure to watch the full CodeRage session! Head over and watch the Embed C Source Delphi video on YouTube!

Learn About Quickly Building REST Applications Using The Powerful RAD Server In Delphi/C++ Builder

Delphi

Over a period of years lot of Web Architectural styles were introduced like, Pipe and filter, Uniform Pipe Filter and some hierarchical styles like client server, Client server stateless, cache, etc. But each style has equal strength and limitations which leads to a modern, scalable, stateless architectural style called REST which is widely adopted. The Word REST is the Abbreviation of the Phase ‘Representational State Transfer’ is the Architectural Design Style introduced in year 2000 presentation by Roy Thomas Fielding one of the Co-founder of HTTP Specification. Web services that conform to the REST architectural style, called RESTful Web services, provide interoperability between computer systems on the internet. REST is not a standard or Protocol. Its a style of architecting a Application. REST provides a set of architectural constraints that, when applied as a whole, emphasizes scalability of component interactions, generality of interfaces, independent deployment of components, and intermediary components to reduce interaction latency, enforce security, and encapsulate legacy systems. The constraints are, Client-Server: Separation of Concern is the principle behind this constraint. Separating the user interface concerns from the data storage concerns, can improve the portability of the user interface across multiple platforms and improve scalability by simplifying the server components. Also it allows the components evolve independently. Stateless communication: Client Server communication should be stateless in nature. Each request from client to server must contain all of the information necessary to understand the request, and cannot take advantage of any stored context on the server. Session state is therefore kept entirely on the client. This constraint induces the properties of visibility, reliability, and scalability. Uniform Interface: Implementations are decoupled from the services they provide, which encourages independent evolvability. The trade-off, though, is that a uniform interface degrades efficiency, since information is transferred in a standardized form rather than one which is specific to an application’s needs. The CRUD Operations Create, Read, Update, Delete are the key methods which is reused across all types of objects. Layered System: To improve behavior for Internet-scale requirements, layered system constraints is added. It Allows an architecture to be composed of hierarchical layers by constraining component behavior such that each component cannot “see” beyond the immediate layer with which they are interacting. REST Elements : The key abstraction of information in REST is a resource. More precisely, a resource R is a temporally varying membership function MR(t), which for time t maps to a set of entities, or values, which are equivalent. The values in the set may be resource representations and/or resource identifiers. A resource can map to the empty set, which allows references to be made to a concept before any realization of that concept exist. REST uses a resource identifier to identify the particular resource involved in an interaction between components. REST connectors provide a generic interface(CURD) for accessing and manipulating the value set of a resource, regardless of how the membership function is defined or the type of software that is handling the request. A representation is a sequence of bytes, plus representation metadata to describe those bytes. Other commonly used but less precise names for a representation include: document, file, and HTTP message entity, instance, or variant. Individual resources are identified in requests, for example using URIs in RESTful Web services. The resources themselves are conceptually separate from the representations that are returned to the client. For example, the server could send data from […]

Learn To Use Styles To Create Visual Stunning VCL And FireMonkey Apps With Delphi/C++ Builder

Delphi

What is a Style: A set of graphical details that define the look and feel of a VCL application/FireMonkey Application, Similar to a theme in Windows. A style permits you to change the appearance of every part and state of a control. For instance, a scroll bar has the following parts: frame, slider, and the two side buttons for each direction. The side buttons, for example, have the following states: pressed, disabled, hot, normal. How to apply styles for an VCL Application: To set a style for your VCL application, select the style in Project > Options > Application > Appearance. See Application Appearance for more details. Note: The VCL style changes the appearance of the application in run-time. However, the Form Designer does not show this changes. Location of Style Files (.vsf Files): The VCL styles that ship with the product are available in C:UsersPublicDocumentsEmbarcaderoStudio21.0Styles. Use the Vcl.Themes.TStyleManager class to load, register, and select styles or to get, register, and unregister a style engine. FireMonkey: Uses lightweight GUI controls on top of a cross-platform abstraction, which is implemented for Windows and other platforms. Lightweight controls mean that every pixel is drawn by FireMonkey, no native (heavyweight) controls are used.FireMonkey controls are arrangements of a tree composed of sub controls, primitive shapes, and brushes, decorated with effects. These compositions are defined as styles, stored in a style book. The individual elements of a style are internally called resources; because that term has several other meanings, the term style-resource is used for clarity. Styles provide a great deal of customizations without sub classing. The FireMonkey styles that are provided with the product are saved in .Style files located in C:Program Files (x86)EmbarcaderoStudio21.0RediststylesFmx. You can load these styles with FireMonkey Style Designer. FireMonkey Style Designer: The FireMonkey Style Designer window, in combination with the Structure view and the Object Inspector, helps you create, edit, and test FireMonkey styles. To work with Platform styles, in the Form Designer or Structure View, double-click a style book component. To work with Custom styles, use the following commands of the shortcut menu displayed when you right-clicked a styled component: Edit Default Style: Opens a new FireMonkey Style Designer window in which you can modify the style for the component class. For example, if you right-clicked a button, you can modify the “buttonStyle” object (a default style for the TButton class) . Edit Custom Style: Opens a new FireMonkey Style Designer window in which you can modify the selected control style. For example, if you right-clicked a button, you can modify the “button1Style” object (a style for this button only). Bitmap Style Designer for VCL and FireMonkey: The Bitmap Style Designer enables you to: Create, edit, and test FireMonkey styles (.style files) Create, edit, and test VCL styles (.vsf files) Convert a VCL style (.vsf file) into a FireMonkey style by saving the VCL style as a FireMonkey style (.style file) Watch this video to check Windows 10 look and feel for VCL and FMX.

Quickly And Easily Build A REST Based Notes App With RAD Server In Delphi And C++

C++ Builder

EMS.NotesResource Sample is a server-client EMS demo. It requires InterBase to be installed on the machine or to connect to a remote server. Make sure that the server is running before you run the sample. InterBase is used to store the information with the server connections. Use the RAD Server Console to display the statistics. The first part consists of creating an EMS Package with a new ResourceName (Notes). Once you run the package, the resource is registered on the EMS server and can be accessed by a client application using REST. The client needs a TEMSProvider to connect to the EMS Server and to retrieve the JSON data. How to Use the Sample Run the EMS Package When you run the NotesResourcePackage project, the EMSDevServer starts automatically. If the configuration file is missing, a wizard launches. Navigate to the location given above and open: Delphi: NotesResourcePackage.dpk C++: NotesResourcePackageCpp.cbproj Press Shift+Ctrl+F9 or choose Run > Run Without Debugging. The EMS Development Server opens. If it is the first time you are using EMS on the machine, you need to run the configuration wizard in order to create the EMS server configuration file. When the Confirm dialog opens, click Yes. Leave all the parameters by default and go through the different windows by clicking Next. Click Finish to close the wizard. An Information window appears. Click OK. The server starts automatically. Minimize it. Run the Client Application The client expects the EMSDevServer to be running at localhost:8080. If you are running the server at a different address, modify the properties of the TEMSProvider component. The Delphi supported platforms for this sample are: 32-bit, 64-bit Windows, and iOS Simulator. To run the sample on iOS Simulator, change the URLHost property of the TEMSProvider component to the IP address from the machine you are launching the sample and running the server.Note: The TEMSProvider component is placed in the NotesClientModule unit. The C++ Supported platforms for this sample are: 32-bit and 64-bit. On the Project Manager, right-click on ProjectGroup1. Click Add Existing Project…. Navigate to: Delphi: Start | Programs | Embarcadero RAD Studio Sydney | SamplesObject PascalDataBaseEMSNotesResourceNotesClientProject.dproj. C++: Start | Programs | Embarcadero RAD Studio Sydney | SamplesCPPDatabaseEMSNotesResourceNotesClientProjectCpp.cbproj. Press F9 or choose Run > Run. Insert a User name and Password and click Signup, or Login if you previously created an account. Click Add to add a new note. Write the note and click Save. Implementation EMS Package The Resource Module has code to register a REST OverView API resource. The resource is called “Notes”. The resource defines a Get, GetItem, Post, PutItem, and DeleteItem method. Once you run the package and have the EMS server running, as a test, you can invoke the GET method by using the browser http://localhost:8080/Notes.Note: An error message appears informing that you need to be logged in to access this information. The NotesStorageU file defines the path of the notes.ini file where the created notes are saved. Client Application The client application has a TEMSProvider component. This component identifies the address of the RAD Server Engine (EMS Server) (http://localhost:8080). The client application also has a TBackendEndPoint for each method. This component identifies the name of a resource (Notes), the method used, and the ResourceSuffix. The information is managed with TJSONObject and TJSONArray.
